In the utility model, by setting a combined device, when in use, the insertion rod and the lever body are inserted, at this time the clamping ring is loosened, the pressure spring loses its restraint and generates elastic force to squeeze the auxiliary rod, the auxiliary rod drives the clamping ring to rotate and at the same time resists against the baffle, at this time the lever body is difficult to slide, the auxiliary rod is pulled to drive the clamping ring away from the baffle, and the lever body can be pulled to separate from the insertion rod. By setting the combined device, the lever body is easy to install, the stability of the equipment is increased, the difficulty of operating the equipment is reduced, and the bumper is easy to replace when the bumper fails, thereby improving the safety of the equipment.

[0014] 2. In the utility model, by setting a protective device, when the lever body collides with an object during use, the lever body is sunken. At this time, the lever body squeezes the pressing plate, and the buffer spring generates elastic force to push the moving rod. The moving rod cooperates with the damper to buffer the impact of the lever body. By setting a protective device, it is convenient to protect the lever body, reduce the situation of the lever body being sunken, increase the stability of the equipment, facilitate the operation of the equipment, and reduce the failure rate of the equipment.
