Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Refer to Figures 1-6 A braking mechanism includes a housing 1, a rotating shaft 2 disposed inside the housing 1, a rear end cover assembly 5 disposed at one end of the rotating shaft 2, a brake pad 8 connected to one side of the rear end cover assembly 5, a clamp 7 installed on the outer side of the brake pad 8, a fixing cover 3 also connected to the rear end cover assembly 5, a protective block 9 disposed inside the fixing cover 3, the rear end cover assembly 5 is installed on the rear side of the rotating shaft 2, a front end cover assembly 4 is installed on the front side of the rotating shaft 2, the rotating shaft 2 is connected between the front end cover assembly 4 and the rear end cover assembly 5 to support the rotating shaft 2, and bearings are connected between the front end cover assembly 4 and the rear end cover assembly 5.

[0024] Specifically, the shaft 2 extends to the rear side of the rear cover assembly 5, and two brake pads 8 are symmetrically arranged. The two brake pads 8 are connected to the arc-shaped surfaces on both sides of the tail end of the shaft 2, and the braking effect of the shaft 2 is achieved by the friction between the two.

[0025] Furthermore, the clamp 7 is wrapped around the two brake pads 8 in circles. The tightness of the brake pads 8 can be adjusted by the number of circles, thereby indirectly changing the braking force.

[0026] In this embodiment, two slots 6 are formed through the rear cover assembly 5, and two locking blocks 10 are symmetrically installed on the fixing cover 3. The locking blocks 10 are correspondingly locked in the two slots 6 to facilitate the installation and removal of the fixing cover 3.

[0028] Working principle: The rotating shaft 2 is supported by the bearing of the rear end cover assembly 5. The rotating shaft 2 contacts the inner circle of the brake pad 8 to generate friction. The brake pad 8 is clamped by the protective block 9 in the fixing cover 3 to prevent the brake pad 8 from rotating. The locking blocks 10 on both sides of the fixing cover 3 are locked in the slots 6 on both sides of the rear end cover assembly 5 to prevent rotation. The outer circle of the brake pad 8 is clamped by the clamp 7 to generate friction between the shaft and the brake pad 8.
