That is, the two pistons 65 of the driving clamp group 60 are actuated in series. In this example, each radial slide groove 67 and the three through grooves 68 constitute a T-shaped groove.

[0056] In this embodiment, the control clamp member 70 is actuated by the driving clamp group 60; the control clamp member 70 has a linkage column 71, three cross bars 72, six first oblique matching parts 73, three upper abutment edges 75 and a lower hole 77. The linkage column 71 is connected to the piston 65 of the driving clamp group 60, and each cross bar 72 is connected to the lower side of the linkage column 71 and is arranged at an equal interval of 120 degrees from each other. Two first oblique matching parts 73 are respectively formed on each cross bar 72, and each first oblique matching part 73 is a slide groove in this embodiment. The upper abutment edge 75 is located above the end of the cross bar 72, and the lower hole 77 is located in the middle of the bottom to accommodate the fixing pin P.

[0057] In this embodiment, the three clamping units 8 are respectively controlled to move by the clamping member 70 , and each clamping unit 8 includes a sliding block 80 and a clamping block 90 .

[0058] In this embodiment, the three sliders 80 each have a radial sliding portion 81, a connecting portion 82, two second oblique matching portions 83, a slot 84, a screw hole 85, and three upper retaining edges 86. The radial sliding portion 81 is arranged in the radial sliding groove 67, the connecting portion 82 moves in each through groove 68 of the driving clamp assembly 60, each second oblique matching portion 83 is a convex rail in this embodiment and is respectively slidably matched to each first oblique matching portion 73 of the control clamp member 70, the slot 84 and the screw hole 85 are located below the connecting portion 82, and the upper retaining edge 86 is located at one end of the second oblique matching portion 83, and the upper retaining edge 86 can be abutted against the upper abutting edge 75 of the control clamp member 70. In this embodiment, the radial sliding portion 81 and the connecting portion 82 constitute a T-shaped block.

[0059] In this embodiment, the three clamping blocks 90 each have a bolt hole 91, a clamping protrusion 92 and a clamping portion 93.

By the relative horizontal movement of the three clamping units 8 in this embodiment, each clamping portion 93 can be accurately parallel to the outer side of the fixed pin P, so the clamping will be more solid. By using the clamping portion 93 of each clamping block 90 in this embodiment as a plane, the three planes clamp the fixed pin at the same time, the center can be kept consistent, the clamping stability is better, and various fixed pins P of different diameters can be clamped more stably. By using the three clamping blocks 90 in this embodiment in a 120 degree orientation, interference with the fixed pins P arranged vertically and horizontally can be avoided. By using the upper abutment edge 75 of the control clamp 70 in this embodiment, it can be limited to the upper stop edge 86 of the driving clamp group 60, which can prevent excessive displacement, that is, stop displacement, and be more secure. By using the lower hole 77 of the control clamp 70 in this embodiment, the fixed pin P can be accommodated, and a longer fixed pin P can be installed.
