The moving insertion rod 511 can slide in the sliding hole 509 and slide out of the limiting hole 510, thereby releasing the connection restriction on the card block 507.

[0068] Example 2:

[0069] On the basis of Example 1, in order to be able to adjust the operating angle of the brake handle 302 so that it can adapt to the operating habits and hand postures of different drivers, a rotating structure for adjusting the handbrake angle is arranged on the adjustment structure.

[0070] Among them, the rotating structure includes a connecting seat 6 arranged on one side of the sliding seat 403, a limiting screw 601 threadedly installed inside the connecting seat 6, and multiple limiting screws 601 opened inside the adjusting disk 404. The limiting screw 601 is movably installed in the corresponding adjusting hole 602. By rotating the limiting screw 601 and unscrewing it from the connecting seat 6 and the adjusting hole 602, the angle restriction of the adjusting disk 404 can be released. At this time, the angle and direction of the handbrake seat 301 and the brake handle 302 can be adjusted by rotating the adjusting disk 404.

[0071] Working principle:

[0072] During installation, the fixing screw 402 can be passed through the corresponding mounting seat 401 and screwed into the tricycle chassis 1 to fix the position of the mounting plate 4. When in use, the height of the handbrake seat 301 and the brake handle 302 can be adjusted according to the user's habits. When adjusting, first pull the stopper 512 so that the stopper 512 drives the insertion rod 511 to move and stretch the auxiliary spring 513. The moving insertion rod 511 can slide in the sliding hole 509 and slide out of the limiting hole 510, thereby releasing the connection limit of the block 507. The clamping block 507 is then pulled out from the adjusting socket 508 and the card slot 506. At this time, the restriction on the winding roller 405 can be released. Then, the winding roller 405 can be rotated to release the wound traction rope 303, or the traction rope 303 can be wound. The retraction and release can be adjusted according to the height position of the brake handle 302. After adjustment, the clamping block 507 is reinserted into the card slot 506 and the corresponding adjusting socket 508. When the stopper 512 is released, the auxiliary spring 513 is stretched. The stopper 512 will shrink and drive the stopper 512 to reset, so that the stopper 512 drives the insertion rod 511 to be reinserted into the limiting hole 510, preventing the block 507 from loosening and re-fixing the position of the winding roller 405. Then, the positioning screw 504 is rotated and unscrewed from the threaded socket 502 to release the position restriction of the sliding seat 403. Then, the sliding seat 403 can be pushed to move its position to adjust the height of the brake handle 302 until the traction sling 303 is in a taut state. After the seat 403 is positioned, the positioning screw 504 is re-screwed into the corresponding threaded hole 502 to fix the height of the sliding seat 403 and the brake handle 302. When operating the brake of the electric tricycle, the brake handle 302 is pulled to drive the L-shaped positioning block 505 to rotate, so that the L-shaped positioning block 505 drives the winding roller 405 to rotate on one side of the handbrake seat 301 through the clamping block 507. The rotating winding roller 405 will pull the traction rope 303, causing the traction rope 303 to trigger the brake.

[0073] By rotating the limit screw 601 and unscrewing it from the connecting seat 6 and the adjustment hole 602, the angle limit of the adjustment disk 404 can be released. At this time, the angle and direction of the handbrake seat 301 and the brake handle 302 can be adjusted by rotating the adjustment disk 404 so as to adjust it according to the user's habits. After adjustment, the limit screw 601 is reinserted into the corresponding adjustment hole 602 and screwed into the connecting seat 6 to re-limit the angle of the adjustment disk 404.

[0074] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
