[0028] When in use, the hydraulic tool handle body 1 is connected to the tool handle joint 5 through the first connecting hole 3 and the second connecting hole 7, and then one end of the axial adjustment screw 8 is extended into the first adjustment hole 4 and abuts against the end surface of the second annular plate 6. When the accuracy needs to be adjusted, the axial adjustment screw 8 is rotated forward or reversely, and the accuracy is adjusted by increasing or decreasing the axial tightening force between the axial adjustment screw 8 and the end surface of the second annular plate 6;

[0029] Through the device described in the present application, the axial precision of the hydraulic tool holder can be adjusted, thereby increasing the overall service life of the hydraulic tool holder.

By rotating the radial adjustment screw 11, radial tightening forces of different magnitudes can be applied to the outer wall of the first annular section 9, thereby achieving a small adjustment of the radial relative position relationship between the hydraulic tool handle body 1 and the tool handle joint 5, so as to achieve the adjustment of the overall accuracy of the hydraulic tool handle.

[0038] Furthermore, the axial adjustment screw 8 and the radial adjustment screw 11 are both tightening bolts.

[0039] Specifically, in this embodiment, the axial adjustment top screw 8 and the radial adjustment top screw 11 are both tightening bolts, and the end face of the axial adjustment top screw 8 matches the end face of the second annular plate 6, for example, both are planes; the end face of the radial adjustment top screw 11 matches the side wall shape of the first annular section 9, for example, both are curved surfaces with consistent curvature, which are conducive to the tightness of the connection between the two.

[0044] Working principle: When in use, first fix the hydraulic tool handle body 1 and the tool handle joint 5 together through the first connecting hole 3 and the second connecting hole 7, and then screw the axial adjustment screw 8 into the first adjusting hole 4 until one end of the axial adjustment screw 8 abuts against the end surface of the second annular plate 6, and by adjusting the axial tightening force between the axial adjustment screw 8 and the second annular plate 6, the hydraulic tool handle body 1 and the tool handle joint 5 are slightly displaced in the axial direction, thereby adjusting the axial accuracy of the hydraulic tool handle; screw the radial adjustment screw 11 into the second adjusting hole 10 until one end of the radial adjustment screw 11 abuts against the outer wall of the first annular division 9, and by adjusting the radial tightening force between the radial adjustment screw 11 and the first annular division 9, the hydraulic tool handle body 1 and the tool handle joint 5 are slightly displaced in the radial direction, thereby adjusting the radial accuracy of the hydraulic tool handle.
