[0025] A threaded section is provided at the bottom of the through hole, and a screw plug 1 is threadedly matched with the threaded section, and 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.

[0026] 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 .

[0035] Stable clamping: The cooperation between the cylindrical positioning pin 7 and the positioning plug pin 12 ensures stable clamping of the thin-walled head 23 during the processing, avoiding processing errors caused by vibration.

[0036] Protecting the end cap: The design of the reset spring 2 can automatically reset the locking connecting rod 10 after the processing is completed, thereby protecting the thin-walled end cap 23 from unnecessary pressure.

[0037] Reusability: All parts of the device are standard parts, which are easy to replace and maintain, improving the durability and reusability of the device.
