[0002] With the increasingly wide application of carbon fiber composite materials, more and more waste carbon fiber composite materials are produced, and recycling technologies for the waste carbon fiber composite materials are gradually matured, and thus more and more rackets are made of the waste carbon fiber materials.

[0003] In the process of racket production and processing, the rackets can be threaded only after being punched by a drilling device. The traditional drilling device generally positions and processes the rackets through a racket mold. The mold can only position and process one type of racket. If different types of rackets are positioned and drilled, the mold needs to be replaced, the replacement steps are complicated, and thus the processing efficiency is low. In addition, the carbon racket made of waste carbon fiber composite materials has a large difference in structure from the carbon racket made of brand-new carbon fiber composite materials. Relatively, the structure of the carbon racket made of waste carbon fiber composite materials is weaker, and thus the drilling positioning device for the carbon racket made of brand-new carbon fiber composite materials is not suitable for the carbon racket made of waste carbon fiber composite materials. In addition, after the racket is drilled, the hole needs to be polished to avoid burrs in the hole and affect the threading quality of the racket.
