[0033] Example 3: Please refer to Figure 6-Figure 8, this embodiment is further explained for other embodiments. The inner support mechanism shown in the figure includes a rotating drum 23 arranged on the inner side of the processing table 2. The rotating drum 23 is connected to the inner side of the processing table 2 through a rotating shaft, so that the rotating drum 23 can rotate with the rotating shaft as the center of the circle. A plurality of sliders 24 are provided on the side of the processing table 2 close to the racket body 4. A movable groove for limiting the sliding of the slider 24 is opened on the outer side of the processing table 2. A guide rod 34 is fixedly installed in the movable groove of the processing table 2. The guide rod 34 slides through the slider 24 to provide a guide for the movement of the slider 24, improve the stability of the movement of the slider 24, and provide support for the slider 24. The block 24 is fixedly installed with a slide bar 25 on one side close to the rotating cylinder 23. The slide bar 25 extends to the inside of the processing table 2. The outer side of the rotating cylinder 23 is provided with an arc groove for the slide bar 25 to slide in a limited position. When the rotating cylinder 23 rotates, the slide bar 25 can be pushed to move through the arc groove. The slide bar 25 can drive the slider 24 to move along the moving groove on the processing table 2, so that multiple sliders 24 are synchronously close to the inner side of the racket frame of the racket body 4. The slide bar 25 has a T-shaped structure to prevent the slide bar 25 from falling off from the arc groove of the rotating cylinder 23. A worm 26 is rotatably installed on the inner side of the processing table 2, and a bevel rack 27 that cooperates with the worm 26 is provided on the outer side of the rotating cylinder 23 to make the worm 26 can drive the rotating drum 23 to rotate through the oblique rack 27. Both ends of the worm 26 and the different-direction screw 16 are fixedly installed with handles 35 to facilitate the rotation adjustment of the worm 26 and the different-direction screw 16. The slider 24 is fixedly installed with two symmetrically distributed support plates 28 on the side away from the slider 25. The slider 24 can drive the support plates 28 to move synchronously. A second mounting rod 29 is provided between the two support plates 28. Two symmetrically distributed pulleys 30 are rotatably installed on the outer side of the second mounting rod 29. The distance between the two pulleys 30 is less than the thickness of the racket body 4, which makes it easy for the pulley 30 to press against the inner side of the racket frame of the racket body 4, so that the center position of the racket frame is aligned with the processing The center position of the circular table 2 is aligned, which facilitates the electric drill bit 3 to accurately drill holes on the outer side of the racket frame. A long groove is provided on the outer side of the support plate 28 for the second mounting rod 29 to limit the sliding movement. A support rod 36 that slides through the second mounting rod 29 is fixedly installed on the inner side of the long groove. A positioning spring 37 is provided on the outer side of the support rod 36. The positioning spring 37 is fixedly installed between the second mounting rod 29 and the inner side of the long groove. The elasticity of the positioning spring 37 can be used to elastically clamp the pulley 30 to the inner side of the racket frame, and when the racket frame rotates and moves along the outer side of the pulley 30, the elasticity of the positioning spring 37 can be used to make the pulley 30 press against the inner side of the racket frame, which is suitable for an elliptical racket frame.

[0034] Working principle: First, the staff moves the racket body 4 close to the outside of the processing table 2, so that the multiple sliders 24 are located in the inner circle of the racket frame, and the racket shaft is placed vertically downward between the two moving frames 7. Then, the staff rotates the worm 26, so that the worm 26 drives the rotating drum 23 to rotate through the bevel rack 27, and the rotating drum 23 drives the slide bar 25 to move through the arc groove. The slide bar 25 drives the slider 24 to move along the inner side of the moving groove on the processing table 2 and the outer side of the guide rod 34. The multiple sliders 24 can move synchronously toward the inner side of the racket frame. The slider 24 drives the second mounting rod 29 to move synchronously through the two support plates 28, so that the two pulleys 30 on the second mounting rod 29 are aligned with the racket frame. , and utilize the elasticity of the positioning spring 37 to elastically clamp the pulley 30 to the inner side of the racket frame, so that the center of the racket frame can be aligned with the center of the processing table 2. Subsequently, the staff rotates the counter-rotating screw 16, so that the counter-rotating screw 16 drives the two moving blocks 17 to approach each other, and the moving block 17 drives the moving frame 7 to move synchronously along the slide groove on the U-shaped plate 6, so that the two moving frames 7 approach each other, and the two connecting rods 8 on the moving frame 7 move synchronously, so that the connecting rod 8 drives the clamping roller 10 to contact the outer side of the racket shaft of the racket body 4 through the first mounting rod 9. As the moving frame 7 moves, the clamping roller 10 can rotate and move along the outer side of the racket shaft and drive the connecting rod 8 swings along the outside of the arc rod 13. At the same time, the clamping roller 10 drives the ratchet 11 to rotate synchronously through the first mounting rod 9, and the connecting rod 8 compresses the arc spring 14. The elasticity of the arc spring 14 is used to make the four clamping rollers 10 elastically clamp the outside of the racket rod. When the staff stops rotating the counter-rotating screw 16, the elastic latch 12 can lock the ratchet 11, so that the four clamping rollers 10 provide vertical resistance for the racket rod, achieving a safe clamping effect. Finally, the staff starts the gear motor 33, so that the gear motor 33 drives the swivel 5 to rotate through the second gear ring 32, and the swivel 5 can drive the U-shaped plate 6 to do a circular motion with the processing frustum 2 as the center. The four clamping rollers 10 can drive the racket frame to rotate and move along the outer side of the pulley 30 through the racket rod, so that the outer side of the racket frame can be drilled by the electric drill 3. In addition, the pulley 30 can provide auxiliary support for the inner side of the racket frame, thereby improving the stability of the electric drill 3 in drilling. At the same time, the swivel 5 can drive the driven gear 20 to rotate through the first gear ring 21, so that the driven gear 20 drives the driven rod 18 to rotate, and the driven rod 18 drives the cleaning brush 22 to rotate. The rotation direction of the cleaning brush 22 is opposite to that of the rotation direction of the swivel 5. The cleaning brush 22 can clean the debris on the surface of the racket frame to prevent the debris from blocking the perforations on the racket frame, thereby achieving the effect of safe drilling.
