[0002] A tennis racket consists of a racket head, a racket throat, and a racket handle. When in use, it also needs to be used with accessories such as tennis strings and shock-absorbing knots. Different tennis rackets are suitable for different people, and most tennis rackets use racket stringing machines during production and processing.

[0003] The existing racket string adjustment and pulling equipment for production is fixed to the ground, and a traction block that moves back and forth is set in front of the racket string reel mounting frame to drag the racket string left and right to form a certain angle with the racket string reel, so that the racket string is arranged on the racket string reel. The traction block mainly drags and supports the racket string through the internal string support wheel, which causes the outer surface of the string support wheel to wear after long-term use, thereby affecting the dragging of the racket string, and in severe cases, the racket string may break. Therefore, after the string support wheel is worn, it needs to be replaced. When replacing the string support wheel, the production machinery needs to be stopped and the string support wheel needs to be replaced, which causes the normal production of the racket string to be delayed when replacing the string support wheel. Therefore, a sports racket string adjustment and pulling equipment is proposed. Utility Model Content
