Four first sliders 15 are arranged inside the first chute 5. A fixing ring 10 is arranged above the installation ring 4, and a plurality of positioning holes 11 are equiangularly opened on the outer side of the fixing ring 10. Second chutes 9 are opened at both ends of the fixing ring 10, and four installation blocks 12 are arranged on the outer side of the fixing ring 10. Second sliders 6 are installed at both ends inside the installation block 12, and a vertical rod 14 is installed at the bottom end of the installation block 12. One end of the installation block 12 away from the fixing ring 10 is installed with a sleeve 8, and a lead screw 13 is arranged inside the sleeve 8. One end of the lead screw 13 penetrates through one end inside the sleeve 8 and is connected with a rotating handle 7, and the other end of the lead screw 13 sequentially penetrates through the sleeve 8, the installation block 12 and the positioning hole 11 and extends into the fixing ring 10;

[0021] The vertical rod 14 is arranged directly above the first slider 15, and the bottom end of the vertical rod 14 penetrates through the top end of the installation ring 4 and is connected to the top end of the first slider 15;

[0025] The inside of the sleeve 8 is in contact with the outer side of the lead screw 13, and the inner wall of the sleeve 8 is provided with an internal thread matching the outer side of the lead screw 13;

[0026] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during the use of this device, first, the machining workpiece to be fixed can be placed inside the fixing ring 10. Then, by utilizing the threaded connection between the sleeve 8 and the lead screw 13, when the handle 7 is rotated, the lead screw 13 can rotate and move inside the sleeve 8, thereby flexibly adjusting the protruding length of the lead screw 13 inside the fixing ring 10. Thus, by using the four lead screws 13 to abut against the outside of the workpiece, it can achieve a good effect. Then, to improve the flexibility of this device, due to the existence of multiple positioning holes 11, the lead screw 13 can be disengaged from the inside of the fixing ring 10 by rotating the handle 7.
