Detailed implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Figures 1-5 Embodiment

[0028] An adjustable grip-distance rotary brake handle includes a mounting bracket 1. One end of the inner top and bottom of the mounting bracket 1 is respectively provided with a limit chute 2. A fixing bracket 19 is slidably installed inside the two limit chutes 2. One side of the fixing bracket 19 is fixedly installed with an adjusting block 3. A positioning hole 4 is opened at the top of the adjusting block 3. An activity cavity 5 is opened on one side of the mounting bracket 1. A positioning arm 6 is movably installed inside the activity cavity 5. A uniformly distributed spring groove 7 is opened on one side of the bottom of the positioning arm 6. A positioning pin 8 adapted to the positioning hole 4 is slidably installed inside the spring groove 7. One end of the positioning pin 8 is fixedly installed with a spring 9. The end of the spring 9 away from the positioning pin 8 is fixedly connected to the inner wall of the spring groove 7.

[0029] The specific usage process is as follows: According to the size of the user's palm, the brake grip distance in this solution can be flexibly adjusted, so it can meet the usage needs of users with different palm sizes. When adjusting, the user first rotates the positioning arm 6 outward to the outside of the mounting bracket 1 to move it out of the inner cavity of the movable cavity 5. At this time, under the extrusion of the adjusting block 3, the positioning pin 8 will move out of the positioning hole 4 and be first squeezed into the corresponding spring groove 7, while compressing the spring 9. After that, the adjusting block 3 can move to adjust its position, and similarly, the fixing frame 19 installed on the adjusting block 3 can also move to adjust its position. Then, the rotating block 13 and the brake handle part 14 can also move to adjust their positions following the fixing frame 19. Among them, moving in the direction of the grip 16 can reduce the grip distance, and vice versa will increase the grip distance. Specifically, how to adjust is adjusted by the user according to the actual usage needs in real time to meet the actual usage needs, providing convenience for the user's work. Here, only the process of reducing the grip distance will be described. After the positioning arm 6 moves out of the inner cavity of the movable cavity 5, the adjusting block 3 and the fixing frame 19 can move. Then the user moves the adjusting block 3 in the direction of the grip 16, and the fixing frame 19 will also move in the two limit sliding grooves 2 accordingly. In this way, the two limit sliding grooves 2 can also play a role in limiting and guiding the movement adjustment of the fixing frame 19 to ensure the accuracy of the grip distance adjustment work. Among them, the rotating block 13 and the brake handle part 14 will also move and adjust following the fixing frame 19. When the adjusting block 3 and the fixing frame 19 move to the appropriate positions, then push the positioning arm 6 back into the movable cavity 5. During this process, the corresponding positioning pin 8 will also be squeezed by the adjusting block 3 into the corresponding spring groove 7, while compressing the spring 9. As the positioning arm 6 continues to move, at this time, the positioning pin 8 at this position will align with the positioning hole 4, and then under the action of the spring 9, it will pop out of the inner cavity of the spring groove 7 and finally snap into the positioning hole 4 to realize the positioning and fixing of the positioning hole 4 and the fixing frame 19, and also complete the positioning and fixing after the adjustment of the rotating block 13 and the brake handle part 14, so that the brake handle part 14 at the current position can meet the usage needs of the user and provide convenience for the user's work. At this time, it is also necessary to loosen the two locking nuts 12 on the shift lever 11, and then adjust the position of the shift lever 11 to ensure that the shift lever 11 can be adapted to the rotating block 13 and ensure the accuracy of the brake handle part 14 after resetting, so as to facilitate the user's next grasping and use. When working, the shift lever 11 moves in the long sliding hole 10, and after the shift lever 11 moves and adjusts to the appropriate position, it is positioned by tightening the two locking nuts 12. In this way, the position of the rotating block 13 after resetting can be adjusted, so as to be adapted to the grip distance after the adjustment of the brake handle part 14 and ensure that the vehicle can be braked normally, providing convenience for the user's work. Among them, the rotating block 13 and the brake handle part 14 are connected together, and the rotating block 13 is also movably installed in the fixing frame 19. In this way, when adjusting, the rotating block 13 and the brake handle part 14 can follow the fixing frame 19 to adjust and move together, ensuring the normal braking function and providing convenience for the user's adjustment work.When in use, the brake lever 14 is for the user to grip, so that the user can pull the brake cable 15 to work by gripping the brake lever 14, and then can control the braking device to work, realizing the braking of the vehicle, providing convenience for the user's work. The surface of the brake lever 14 is also processed with rounded edges, so that the user will not feel uncomfortable when gripping, providing convenience for the user's work. When braking the vehicle, the user squeezes the brake lever 14, and under the pull of the brake lever 14, the brake cable 15 will drive the braking device to work, realizing the braking of the vehicle.

[0030] Therefore, a structural design that can flexibly adjust the grip distance according to the actual usage situation and the size of the user's palm is adopted. Whether it is a larger palm or a smaller palm, it can comfortably and flexibly grip and operate the brake lever, easily and accurately complete the braking of the vehicle, ensure the safety of the user when driving the vehicle, and provide convenience for the user's work.

[0032] Specifically, due to the arrangement of the long sliding hole 10, the retaining rod 11 and the locking nuts 12, during work, the retaining rod 11 moves in the long sliding hole 10. After the retaining rod 11 moves and adjusts to the proper position, it is positioned by tightening the two locking nuts 12. In this way, the reset position of the rotating block 13 can be adjusted, so as to adapt to the adjusted grip distance of the brake lever 14, ensure that the vehicle can be braked normally, and provide convenience for the user's work.

[0033] A rotating block 13 is movably installed inside the fixing bracket 19. A notch is provided on one side of the rotating block 13, and the retaining rod 11 is stuck in the notch on the rotating block 13.
