A cable 2 is provided inside the positioning rod 84. The cable 2 is electrically connected to the contact switch 2 85, and the cable 2 is electrically connected to the indicator light 83. A support shaft 86 is installed inside the stamping upper die 6 through a bearing. A winding wheel 87 is fixedly connected to the upper end of the support shaft 86. The winding wheel 87 is in contact with the cable 2. A socket 8 is provided on the surface of the support shaft 86. 9. A fixing plate 890 is fixedly connected to the upper end of the stamping upper die 6 and located in front of the support shaft 86. An insert rod 891 is slidably connected inside the fixing plate 890. The insert rod 891 is slidably connected to the socket 89. A fixing disk 892 is fixedly sleeved on the outer side of the insert rod 891.
