Since the second sliding member 5 is configured to slide the second sliding member 5, the first locking member 6 is linked to disengage from the positioning hole 11 and simultaneously drives the second locking member 7 to disconnect from the locking mechanism, that is, when the first locking member 6 is disengaged from the positioning When the hole 11 realizes the length adjustment function of the handle bracket, the second locking piece 7 is disconnected from the locking mechanism that keeps the bracket in the open state and cannot realize the forward adjustment. The folding function of the wheel bracket and the rear wheel bracket; at the same time, when sliding the first sliding part 4, the second locking part 7 drives the locking mechanism to unlock, realizing the folding function of the front wheel bracket and the rear wheel bracket. At this time, the first locking part 6 and the positioning If hole 11 is not matched, the handle bracket length adjustment function cannot be realized. Therefore, one can choose to realize the handle bracket length adjustment function and the front wheel bracket and rear wheel bracket folding function. When realizing one of the handle bracket length adjustment function and the front wheel bracket and rear wheel bracket folding function, it can effectively avoid false triggering. Another feature that avoids the danger of use.

Optionally, the first sliding member 4 is axially slidable on the sliding body 3, the first sliding member 4 is connected to the first pulling wire 41, the first pulling wire 41 is connected to the actuating mechanism, and the actuating mechanism can pull the first pulling wire 41 to move, Thus, the first sliding member 4 is driven to slide. The second slider 5 is axially slidable on the sliding body 3. The second slider 5 is connected to the second pull wire 51. The second pull wire 51 is connected to the actuating mechanism. The actuating mechanism can pull the second pull wire 51 to move, thereby driving the second pull wire 51 to move. The slider 5 slides.

Optionally, a return spring 9 is provided between the second locking member 7 and the first sliding member 4 to drive the second locking member 7 to return.

In the initial state, that is, when neither the first sliding member 4 nor the second sliding member 5 slides, the elastic restoring force of the first elastic restoring member 81 is greater than the elastic restoring force of the second elastic restoring member 82. The elastic return force of 82 is greater than the elastic return force of return spring 9. The elastic restoring force of the maximum compression amount of the restoring spring 9 is smaller than the elastic restoring force of the second elastic restoring member 82 in the initial state. The elastic restoring force of the second elastic restoring member 82 at the maximum compression amount is smaller than the elastic restoring force of the first elastic restoring member 81 in the initial state.

When the second slider 5 is configured to slide the second slider 5 , the first chute 52 drives the first locking member 6 to disengage from the positioning hole 11 , and at the same time the second chute 54 drives the second locking member 7 to disconnect from the locking mechanism. . As shown in Figures 3 and 4, when the first locking part 6 cooperates with the positioning hole 11 and the second locking part 7 cooperates with the locking mechanism, at this time, the first locking part 6 is located at the lowest position, that is, the position closest to the locking mechanism. , when the actuating mechanism pulls the second pull wire 51 to move, it drives the second sliding member 5 to slide, and the first inclined groove 52 drives the first locking member 6 to move radially inward and disengage from the positioning hole 11.
