A limiting ring 6 is fixedly connected to the middle section of the pin body of the sliding pin 4, and the limiting ring 6 contacts the inner surface of the tooling base 1. Through the setting of the limiting ring 6, it has a limiting effect on the sliding pin 4. An arc groove is formed inside the rotating disk 8, and the lower section of the rod body of the sliding pin 4 is located in the arc groove. Through the setting of the arc groove, the sliding pin 4 can be subjected to radial pushing and pulling forces from the rotating disk 8.
[0027] Please refer to Figures 5-6 , a locking mechanism 9 is arranged on the outer side of the tooling base 1. Through the setting of the locking mechanism 9, it has an anti-loosening effect on the rotating disk 8. The locking mechanism 9 includes a fixing piece 91 fixedly connected to the outer side of the tooling base 1. A locking pin 92 is slidably connected to the inside of the fixing piece 91. The lower end of the locking pin 92 is inserted into the rotating disk 8. A retaining ring 93 is fixedly connected to the lower section of the pin body of the locking pin 92. A spring 94 is sleeved on the outer side of the pin body of the locking pin 92. One end of the spring 94 is fixedly connected to the retaining ring 93, and the other end of the spring 94 is fixedly connected to the fixing piece 91. Through the setting of the spring 94, the elastic force can act on the locking pin 92 through the retaining ring 93.
[0028] Please refer to Figure 6 , a corrugated sleeve 95 is fixedly connected between the retaining ring 93 and the fixing piece 91 and on the outer side of the spring 94, and the corrugated sleeve 95 is made of rubber material.
