[0008] In addition, a preferred structure is that a stroke limit block is fixedly connected inside the lower die. Through the setting of the stroke limit block, it has a limiting effect on the reset position of the side push pin.

[0009] In addition, a preferred structure is that a guiding block is fixedly connected to the middle section of the pin body of the side push pin. A fixing block is fixedly connected to the inside of the lower die. A guiding rod is fixedly connected to one side of the fixing block close to the guiding block.
