Two positioning seats 5 are symmetrically arranged, and the two positioning seats 5 are slidably connected to the base plate 3 through the longitudinal grooves 7. A third waist-shaped hole 24 is provided on the positioning seat 5. The length direction of the third waist-shaped hole 24 is parallel to the longitudinal groove 7. The third waist-shaped hole 24 is arranged above the transverse groove 6, so that the positioning seat 5 can be fixed by bolts inserted into the third waist-shaped hole 24 and the transverse groove 6.

[0038] A rotating seat 20 is fixed to the base plate 3 by bolts. The rotating seat 20 is arranged between the two groups of horizontal slide grooves 6. A rotating hole is opened on the rotating seat 20. A lower screw 21 is rotatably arranged on the rotating hole through a bearing. Two limit members 22 are arranged on the lower screw 21. The two limit members 22 are respectively located on both sides of the rotating seat 20, and are used to limit the axial movement of the lower screw 21; force blocks 23 are fixed to the two lower mounting seats 4 by bolts. The force blocks 23 are arranged on the side close to the longitudinal slide groove 7.

[0047] First, hang the cylinder 31 onto the support seat 10 of the lower clamping member 2, and the axial direction of the cylinder 31 is parallel to the longitudinal slide groove 7. At this time, the outer wall of the side hole 32 of the cylinder 31 falls on the support seat 10, and then rotate the lower positioning pin 8 to adjust the cylinder 31 to a horizontal state, and rotate the side positioning pin 9 to adjust the axial direction of the cylinder 31. Then use the second waist-shaped hole 17 to extend the clamping block 14 into the side hole 32 of the cylinder 31, and then tighten the tightening member 13 to clamp both sides of the cylinder 31. Finally, install the upper clamping member 1 to the top of the lower clamping member 2, adjust the distance between the two upper pressure plates 26 through the first waist-shaped hole 28, and adjust the height of the upper pressure plate 26 through the vertical screw 27, so that the upper positioning pin 30 is close to the cylinder 31, and rotate the upper positioning pin 30 to fix the top of the cylinder 31.
