[0025] An embodiment of this application discloses an auxiliary fixing tool for stringing a badminton racket. Refer to Figures 1-3 , an auxiliary fixing tool for stringing a badminton racket, including a base 1, two relatively installed clamping assemblies 2 are installed on the base 1, the clamping assembly 2 includes a support 201 installed on the base 1, a rotating notch is opened on the support 201, two clamping arms 202 are rotatably installed in the rotating notch, a T-shaped sliding groove is installed at the end of the clamping arm 202, a fine-tuning assembly 4 is installed in the T-shaped sliding groove, the fine-tuning assembly 4 includes a roller 404 slidably installed in the T-shaped sliding groove, a threaded rod 401 is rotatably installed on the roller 404, a nut 402 is threadedly installed on the threaded rod 401, the top of the threaded rod 401 is installed with a clamping seat 403, and a driving assembly 3 is installed inside the two supports 201. By driving the clamping arm 202 to rotate through the driving assembly 3, the clamping seat 403 fixes the racket frame;

[0026] By adopting the above technical solution, the bidirectional screw 301 is used to drive the moving block 302 and the driving wheel 303 to move, adjust the opening and closing angle of the clamping arm 202, and expand and fix the racket frame through the positioning post 4032 to achieve multi-point clamping. According to the differences of different racket frames, the nut 402 can be loosened, and the relative positions of the support plate 4031 and the positioning post 4032 can be adjusted along the clamping arm 202 to avoid blocking the stringing holes on the racket frame and facilitate subsequent stringing.

[0027] Refer to Figure 3 , a torsion spring 203 is installed between the clamping arm 202 and the inner wall of the rotating notch, and the torsion spring 203 is used to push the clamping arm 202 to reset.

[0028] Refer to Figure 1, the driving assembly 3 includes a bidirectional screw 301, two moving blocks 302 and a driving wheel 303. The bidirectional screw 301 rotates through the two supports 201 and is connected with a wrench for driving the moving blocks 302 to move. The two moving blocks 302 are threadedly sleeved at both ends of the bidirectional screw 301 and are rotatably connected with the driving wheel 303. The driving wheel 303 is located inside the corresponding two clamping arms 202 and is in rolling abutment with the clamping arms 202 for driving the driving wheel 303 to move so as to expand the two side clamping arms 202.

[0029] Referring to Figure 2 , a guide rod 5 is installed on the lower side of the bidirectional screw 301. The end of the guide rod 5 slidably passes through the two moving blocks 302 and is fixedly connected with the corresponding two supports 201.

[0030] Referring to Figure 3 , a slider 405 is slidably installed on the upper side of the roller 404 in the T-shaped chute. The slider 405 is fixedly connected with the threaded rod 401.

The clamping seat 403 includes a support plate 4031 fixedly installed at the top of the threaded rod 401, and a positioning column 4032 is fixedly installed in the middle of the top end of the support plate 4031.

[0031] The implementation principle of the badminton racket stringing auxiliary fixing tool in the embodiment of the present application is as follows: Place the racket frame on the support plate 4031, turn the bidirectional screw 301, drive the moving blocks 302 and the driving wheel 303 to move through the bidirectional screw 301. The driving wheel 303 pushes the moving blocks 302 to expand outwards, so that the positioning column 4032 fixes the racket frame by outward expansion, realizing multi-point clamping. When it is necessary to finely adjust the position of the positioning column 4032 according to the differences of different racket frames, loosen the nut 402 to release the extrusion of the nut 402 on the clamping plate 406 and the clamping arm 202, so that the roller 404 can move along the clamping arm 202, adjust the relative position of the support plate 4031 and the positioning column 4032. After adjusting to the appropriate position, tighten the nut 402 to avoid blocking the stringing holes on the racket frame and facilitate subsequent stringing.
