[0028] Specifically, if Figure 1 、 Figure 3 and Figure 4 As shown, when in use, when the electric push rod 27 is started to extend, the second inclined platform 26 at the front end can be driven to move.

The second inclined platform 26 cooperates with the first inclined platform 25 to push the brake plate 22 to move toward the outside of the support tube 7. When the friction plate 23 on the surface of the brake plate 22 contacts the rotating ring 8 rotating on the outside of the support tube 7, the friction force can assist the rotating ring 8 to perform limit braking. When the rotating ring 8 stops rotating, the friction between it and the conveyor belt can be increased, assisting the conveyor belt and the conveyed objects to perform limit braking.
