`locked, in particular to a retractable handle which can be quickly locked for use on a lawn
`mower.
`
`Background Art
`[0002]
`A lawn mower is a lawn maintenance device, a lawn mower typically comprises a
`cutting device and a chassis carrying the cutting device. The chassis is mounted on a frame
`having four wheels, and one end of the frame is provided with a handle for pushing the mower
`body during operation.
`[0003]
`When a user finishes using a lawn mower, the mower needs to be transported
`from the lawn to the storage place. This involves the storage of the mower. In the existing
`technology, the handle of the mower usually does not have a retractable function, and the handle
`is long. It takes up a lot of space, so it is difficult to adapt from a large volume when used to
`mow a lawn to a small volume at the time of storage.

`If the handle of the mower is provided with a retractable structure, the handle
`portion can be quickly retracted during transportation and storage, and the handle portion can be
`quickly expanded and has sufficient strength and reliability when used as a lawn mower. The
`foregoing is undoubtedly one focus of research and development of lawn mower handles, which
`will bring great convenience to users.

`Description

`Page 5 of 7 pages
`
`The main body portion 35 of the housing is transversely disposed between the two symmetrical
`tubular members of the first handle portion 21. The connecting device 3 comprises a pushing
`driving member 31 which is disposed substantially in the middle of the main body portion 35 and
`can be manually operated by an operator. The pressing driving member 31 can drive each of the
`left and right pressing mechanisms located on the left and right sides. The left and right pressing
`mechanisms each are configured to release or press the tubular free ends of the second handle
`portion 22 into the left and right tubular members of the first handle portion 21. Moreover, the
`left and right pressing mechanisms have the same structure.
`
`The left pressing mechanism is used as one example for detailed description. As
`[0025]
`shown in Figure 3, the pressing mechanism includes a pivoting member 32 that can be driven by
`the driving member 31, a resetting member 33 that cooperates with the driving member 31 to
`pivot the pivoting member 32, and a pressing member 37 abuts against the pivoting member 31.
`The driving member 31 can be connected to the pivoting member 32 in an abutting manner, and
`the pivoting member 32 is pivotally disposed in the housing of the connecting device 3 about the
`pivot 34, and the pivot 34 is directly formed on the housing of the connecting device 3. The
`pivoting member 32 has a first end 321 abutting against the driving member 31 and a second end
`322 pressing the pressing member 37. The pressing member 37 is pressed through a hole 211
`provided on the first handle portion 21 to further press on the tube of the second handle portion
`22. A resetting member 33 is also applied to the pivoting member 32. The resetting member 33
`may preferably be a pressing spring 33a. The pressing spring 33a and the driving member 31 are
`respectively disposed above and below the pivoting member 32. Thus, when it is desired to lock
`the second handle portion 22 relative to its first handle portion 21 of the handle 2, the pivoting
`member 32 pivots about the pivot 34 under the pressing spring 33a and its second end 322
`presses the pressing member 37 on an outer wall of the tube of the second handle portion 22. At
`this time, the pivoting member 32 is in the first pivoting position about the pivot 34. In reference
`to Figure 4, when it is necessary to retract the second handle portion 22 relative to its first handle
`portion 21 of the handle 2, it is only necessary to press the driving member 31 to overcome the
`top force of the pressing spring 33a. Such that the pivoting member 32 pivots in an opposite
`direction about the pivot 34, thereby releasing the pressing member 37 and the second handle

`
`portion 22. At this time, the pivoting member 32 is in the second pivoting position about the
`pivot 34.
`
`In this embodiment, in the locking state, one end of the pivoting member 32
`[0026]
`presses the pressing member 37 firmly against the second handle portion 22, and the pressing
`member is preferably a pressing block having a large contact area with the outer wall of the
`second handle portion 22, which can increase the friction between the pressing member 37 and
`the second handle portion 22; in addition, it may illuminate a radial gap present when the tube of
`the second handle portion 22 and the tube of the first handle portion 21 are connected in a
`sleeving manner, so that the second handle portion 22 does not move relative to the first handle
`portion 21. The pressing member 37 is not limited to the form of a pressing block, and in other
`embodiments, the pressing member 37 may be integrally formed with the pivoting member 32.
`
`The connecting device of the present utility model may also be provided with a
`[0027]
`further locking structure to enhance the strength of the handle and the reliability of the locking
`function. The further locking structure includes a pin 36, a resetting spring 35 for resetting the
`pin. In this case, the pin 36 is inserted into a first insertion hole 212 of the first handle portion 21
`and a second insertion hole 222 of the second handle portion 22. The second handle portion 22
`can be further locked on the first handle portion 21, and the second insertion hole 222 on the
`second handle portion 22 can be arranged as a row of equally spaced holes (not shown). The pin
`36 is optionally placed in one hole among the row of holes. The pin 36 is coupled to the pivoting
`member 32. Preferably, the end of the pivoting member 32 that abuts the pressing member 37
`extends from a projection 323 for pulling the pin 36 out of the insertion hole.
`
`The operation procedure of the lawn mower handle of the present utility model is
`[0028]
`as follows: pressing the driving member 31 to drive the pivoting member 32 to pivot, so that the
`pressing member 37 is released. At the same time, the pivoting member 32 drives the locking pin
`36 to translate, so as to be disengaged from the insertion hole 222 of the second handle portion
`22; so far, the two pressing members 37 and the locking pin 36 are in an unlocked state.
`At this time, the tube of the free end of the second handle portion 22 can slide freely in the outer
`tube of the first handle portion 21. When the user’s hand leaves, the above components are
`

`Page 7 of 7 pages
`
`moved in opposite directions, and the inner tube of the second handle portion 22 can be firmly
`locked with the outer tube of the first handle portion 21 without relative displacement.
`
`The handle for the lawn mower disclosed in the present utility model is not
`[0029]
`limited to the contents described in the above embodiments and the structure represented by the
`drawings. For example, the free end of the second handle portion can also be sleeved over the
`first handle portion. Therefore, correspondingly the hole for accommodating the pressing
`member is disposed on the second handle portion. The resetting member that cooperates with the
`driving member to drive the pivoting member is also not limited to a pressing spring, and may be
`a tension spring. Meanwhile, the resetting member is not limited to being disposed on opposite
`sides of the pivoting member with respect to the driving member, and even the resetting member
`is not required, as manual resetting may be adopted. The first end of the pivoting member can
`also extend out of the housing of the connecting device to operate in place of the driving member.
`The concept of the present invention can also be achieved when the pressing mechanism of the
`above connecting device has only one set instead of two sets on both the left and right sides. In
`summary, obvious changes, substitutions or modifications to the shapes and positions of the
`components of the present utility model are within the scope of the present utility model.
