A slide bar 25 is fixedly installed on one side of the block 24 close to the rotating cylinder 23. The slide bar 25 extends to the inside of the processing truncated table 2. An arc groove is provided on the outside of the rotating cylinder 23 for the slide bar 25 to limit the sliding movement. 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 truncated 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 the arc groove of the rotating cylinder 23. A worm 26 is rotatably installed on the inner side of the processing truncated table 2. An oblique rack 27 matching the worm 26 is provided on the outside of the rotating cylinder 23, so that the worm 26 can be rotated. The rotating drum 23 can be driven to rotate by the bevel rack 27.

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 arranged 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, so that the pulley 30 can be pressed 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 positions of the truncated table 2 are aligned, which is convenient for the electric drill 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.

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 outer side of the processing truncated table 2, so that the multiple sliders 24 are located in the inner circle of the racket frame, and the racket rod 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 oblique rack 27, and the rotating drum 23 drives the sliding rod 25 to move through the arc groove. The sliding rod 25 drives the slider 24 to move along the inner side of the moving groove on the processing truncated table 2 and the outer side of the guide rod 34, and the multiple sliders 24 can move synchronously to 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. The inner side of the racket frame is contacted, and the elasticity of the positioning spring 37 is used to make the pulley 30 elastically clamp the inner side of the racket frame, so that the center of the racket frame can be aligned with the center of the processing truncated table 2. Subsequently, the staff rotates the counter-rotating screw 16 to make the counter-rotating screw 16 drive the two moving blocks 17 to approach each other, and the moving blocks 17 drive the moving frame 7 to move synchronously along the sliding groove on the U-shaped plate 6, so that the two moving frames 7 are close to 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, and 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 outer side 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 outer side 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, thereby achieving a safe clamping effect. Finally, the staff starts the gear motor 33, so that the gear motor 33 drives the rotating ring 5 to rotate through the second gear ring 32, and the rotating ring 5 can drive the U-shaped plate 6 to make a circular motion with the processing truncated table 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, and the outer side of the racket frame can be punched by the electric drill 3. In addition, the pulley 30 can provide auxiliary support for the inner side of the racket frame to improve the stability of the electric drill 3 in punching holes. 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 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 punching.
