[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The fixed hook and the movable long hook of the utility model are placed horizontally, and the rotation of the screw rod drives the slide plate to move, so that the movable long hook moves horizontally and stretches the rubber ring. When the unqualified rubber ring breaks, the hook is thinner and the rubber ring can fall directly downward into the collection box for easy collection. In addition, the screw rod is protected by the movable baffle and the fixed plug plate. Even if the broken rubber ring splashes upward, it will be blocked to avoid adhering to the surface of the screw rod and affecting the transmission of the screw rod and the slide plate.
