The driving cylinder is arranged on the other side of the fixed frame. The guide rod passes through the limiting column, the reversing motor and the fixed frame and is linked with the driving cylinder to realize the reciprocating movement of the guide rod up and down. The side wall of the limiting column is provided with four guide holes. The guide block on the support block extends from the outside to the inside into the limiting column through the guide holes and contacts with the guide rod. The guide block and the support block are pushed to move outward through the conical section on the guide rod. The annular elastic belt is sleeved on the outside of the support block to realize the inward movement of the guide block and the support block.
