[0022] A threaded section is provided at the bottom of the through hole, and a screw plug 1 is threadedly engaged with the threaded section. A return spring 2 is provided between the top of the screw plug 1 and the bottom of the locking link 10. A mounting nut 11 is provided at the top of the locking link 10, and the locking disk 9 is fixed to the locking link 10 by the mounting nut 11.

[0023] A lower wedge block 101 is provided on the locking link 10 , an adjustment hole is provided in the vertical through hole in the clamp body 3 , a locking screw 6 is provided in the adjustment hole, an upper wedge block 61 is provided on the locking screw 6 , and the upper wedge block 61 cooperates with the lower wedge block 101 .

[0024] One end of the locking screw 6 extends out of the adjustment hole and is threadedly connected to the locking nut 5 . An adjusting wrench 21 is provided on the outside of the locking nut 5 .

[0025] A positioning pin hole 33 is provided on the clamp body 3 , and a positioning pin 12 is provided in the positioning pin hole 33 .

[0031] Easy to operate: through the threaded connection between the locking nut 5 and the locking screw 6, and the rotation operation of the adjusting wrench 21, the adjustment process of the device is simple and fast, thereby improving work efficiency.

[0032] Stable clamping: The cooperation between the cylindrical positioning pin 7 and the positioning pin 12 ensures stable clamping of the thin-walled head 23 during the processing, avoiding processing errors caused by vibration.

[0033] Protect the head: The design of the reset spring 2 can automatically reset the locking connecting rod 10 after the processing is completed, protecting the thin-walled head 23 from unnecessary pressure.

[0034] Reusability: All components of the device are standard parts, which are easy to replace and maintain, thus improving the durability and reusability of the device.
