The clamping avoidance cylinder 14 is installed on the right side of the one-bar shaft clamping jaw 13 to provide avoidance function when the clamping jaw clamps the one-bar shaft, ensuring the stability of the one-bar shaft at the end of the pressing. The latch avoidance cylinder 15 is installed on the upper side of the clamping avoidance cylinder 14 to control the avoidance of the latch body 12, so that the latch can automatically retreat at the last stage of the pressing.
