[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A fixing fixture for processing a tennis racket comprises a workbench 1, a centering component and a clamping component, wherein the centering component comprises a positive and negative thread screw 2, a slider 3, a motor 5 and a centering plate 6, wherein a slide groove 4 is provided on the workbench 1, wherein the positive and negative thread screw 2 and two groups of sliders 3 arranged symmetrically are provided in the slide groove 4, wherein the output end of the motor 5 passes through the workbench 1 and is connected to the positive and negative thread screw 2, wherein the slider 3 is threadedly connected to the positive and negative thread screw 2, wherein the centering plate 6 is also provided on the slider 3, wherein the centering plate 6 is close to the positive and negative thread screw 2. A receiving groove 7 is provided at one end near the center of the workbench 1, and the clamping assembly includes a movable block 8, a bolt 9, a bearing 11 and a clamping piece 12. A movable groove 13 penetrating the receiving groove 7 is provided on the centering plate 6, and the movable block 8 is adapted to the movable groove 13. The bolt 9 is provided at one end of the centering plate 6 away from the center of the workbench 1, and the bolt 9 extends into the movable groove 13 and is connected to the movable block 8 through the bearing 11. The movable block 8 extends into the receiving groove 7 and is provided with the clamping piece 12.

[0024] At first, the gap between the two sets of centering plates 6 is large. By rotating the bolt 9, the position of the movable block 8 in the movable groove 13 is adjusted, and then the position of the clamping piece 12 in the receiving groove 7 of the centering plate 6 is adjusted. The bolt 9 is connected to the movable block 8 through the bearing 11 to prevent the movable block 8 from rotating with the rotation of the bolt 9. It should be noted that the width of the receiving groove 7 is less than half of the maximum outer diameter of the clamped material to ensure that the equipment can stably center and clamp the material. After adjusting the bolt 9, start the motor 5. The motor 5 drives the positive and negative thread screws 2 to rotate, and the slider 3 moves toward each other under the limit of the slide groove 4 on the workbench 1. The movable groove 13 and the clamping assembly are set to several groups. The two sets of centering plates 6 move toward each other to clamp the material. If the specifications and models of the material are not clear, you can rotate to center and clamp the material first, and then adjust the bolt 9 to ensure the stability of the material clamping. The motor 5 uses a stable servo motor 5.

[0025] If the movable groove 13 and the movable block 8 are both cylindrical, the movable block 8 may still rotate. For this reason, the movable groove 13 and the movable block 8 are both rectangular. After long-term use, or when clamping rackets of different specifications, it is inevitable to replace the clamping member 12. In this embodiment, the movable block 8 is provided with a connecting groove 10 near the end of the bolt 9, the inner ring of the bearing 11 is connected to the bolt 9, and the outer ring of the bearing 11 is connected to the side wall of the connecting groove 10. A magnetic sheet 14 is also embedded in the connecting groove 10, and the magnetic sheet 14 is magnetically connected to the bolt 9, and the movable block 8 is magnetically connected to the bolt 9. The end of the bolt 9 with the bearing 11 is inserted into the movable block 8, which is convenient for assembly and disassembly.
