[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a badminton racket with an adjustable club, comprising a racket hoop 1, a handle 2 connected to the outer edge of the racket hoop 1 and having a telescopic function, and an adjusting assembly 3 for adjusting the telescopic function of the handle 2. The handle 2 is an elastic telescopic structure, and the adjusting assembly 3 comprises a winding roller 31, a traction rope 32 and a locking member 33. One end of the winding roller 31 is rotatably connected to one side of the non-action portion of the handle 2, one end of the traction rope 32 is wound around the winding roller 31 and the other end is fixedly connected to one side of the action portion of the handle 2. When the winding roller 31 rotates forward, the handle 2 contracts, and when the winding roller 31 rotates reversely, the handle 2 extends. The locking member 33 is used to lock the winding roller 31, that is, when the traction rope 32 is wound around the winding roller 31, the handle 2 shortens, and vice versa, the handle 2 extends. At this time, when the bottom of the handle 2 hits the ground, the handle 2 will adaptively elastically contract and buffer, thereby avoiding damage to the handle 2 due to impact. A winding groove 313 is provided on the outer periphery of the winding roller 31 , and the arrangement of the winding groove 313 has the function of preventing the traction rope 32 from being supported in the groove.

[0023] Specifically, the handle 2 includes an inner rod 21, a support spring 22 and an outer sleeve 23. The inner rod 21 is sleeved on one end of the outer sleeve 23, and the other end of the inner rod 21 is fixedly connected to the outer edge of the racket ring 1. The support spring 22 is located in the outer sleeve 23 and one end of the support spring is against one end of the inner rod 21. The support spring 22 continuously applies an elastic force to push the inner rod 21 outward. The outer sleeve 23 is a hand-held component.

[0024] Furthermore, a rotating shaft 311 is provided at one end of the winding roller 31, and the rotating shaft 311 is provided to pass through the inner rod 21. The locking piece 33 is a U-shaped rod structure and a guide shaft 331 is fixedly connected to the middle thereof and slides with one end of the rotating shaft 311. The inner rod 21 passes through the U-shaped inner cavity of the locking piece 33, and a limiting groove 312 is provided at one end of the winding roller 31 to be plugged into the locking piece 33. When the two free ends of the locking piece 33 are inserted into the limiting groove 312, the winding roller 31 cannot rotate. Otherwise, the winding roller 31 can be easily rotated to achieve the function of retracting and releasing the traction rope 32.

[0025] In this embodiment, a guide hole 3111 which is slidably connected to the guide shaft 331 is provided at one end of the rotating shaft 311. A tension spring 5 is provided in the guide hole 3111 to connect the bottom of the guide hole 3111 and one end of the guide shaft 331. The function of the tension spring 5 is to apply a pulling force to the locking member 33 to move in the direction of the winding roller 31, which has the function of preventing the locking member 33 from disengaging from the limiting groove 312 and has a good relaxation effect.

[0026] Furthermore, a pull rod 332 is fixedly connected to the side of the locking member 33 facing away from the guide shaft 331 . The pull rod 332 is a handheld component for manually controlling the locking member 33 to disengage from the limiting groove 312 .

[0027] In this embodiment, a hanging ring 231 near the mouth is fixedly connected to the outside of the outer sleeve 23 , and the hanging ring 231 is connected to the traction rope 32 . This arrangement facilitates the traction rope 32 to be tied through the hanging ring 231 .

[0028] Working principle: When the length of the handle 2 needs to be shortened, manually press the bottom of the outer sleeve 23 against the ground, then press the racket ring 1 downward, and then manually pull the pull rod 332 outward with force. The pull rod 332 will disengage from the limiting groove 312. At this time, the winding roller 31 can be manually rotated to collect the traction rope 32, and then the pull rod 332 can be released. When the locking piece 33 is inserted into the limiting groove 312, the shortening adjustment of the handle 2 is completed, and the outer sleeve 23 can be held by hand for use.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
