When the gas cylinder suddenly breaks or the hydraulic cylinder suddenly breaks, the upward force of the spring 34 on the connecting rod 32 can prevent the piston rod 311 from slowly loosening due to the absence of gas pressure or hydraulic pressure, so that the die head mounting frame 2 can continue to move and fly out, thereby avoiding damage to the equipment and injury to the personnel.

Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. Here, all the embodiments need not and cannot be exhausted.
