The top of the fixed column 904 passes through the top of the bent rod 1001. The bent rod 1001 is movably connected to the inside of the positioning cavity 8 through a second rotating shaft. The bent rod 1001 is used in conjunction with the movable column 1002. The top of the movable column 1002 passes through the top of the bent rod 1001.

[0034] The working principle of this utility model:

[0035] When in use, the moving rod 901 is pulled to the right, and the moving rod 901 drives the cross bar 902 to move to the right according to the moving trajectory provided by the limit block 14. The cross bar 902 drives the fixed column 904 to move to the right while stretching the compression spring 903, and the surface of the fixed column 904 squeezes the inner wall of the travel groove 13 so that the two bent rods 1001 rotate to the opposite side with the second rotating axis as the center. During rotation, the inner wall of the travel groove 13 squeezes the surface of the moving column 1002 so that the two moving columns 1002 move to the opposite side. The moving column 1002 drives the positioning rod 1003 to move to the opposite side according to the moving trajectory provided by the limit block 12, so that the positioning rod 1003 moves to the inside of the positioning cavity 8. At this time, the upper clamping block 5 can be adjusted. After completion, the moving rod 901 is released, and the positioning rod 1003 is reinserted into the inside of the fixed groove 11 through the pullback force of the compression spring 903.
