When the acting force of the wedge block on the steel plate is reduced, the piston rod of the driving cylinder stretches out to drive the push rod to move, the push rod pushes the wedge block to push out, the sharp angle at the top of the wedge block continuously props against the steel plate, and the holding force can be effectively increased. Moreover, the sharp angle at the top of the wedge block can be pressed into the surface of the steel plate, so that the reliability of preventing the steel plate from deforming is further improved. Thus, the locking effect of the side locking mechanism on the steel plate is good.
