DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 - Figure 5 As shown, the embodiment of the utility model provides: comprising a handle 2, a lifting slot 11 is opened in the middle of the handle 2, a support rod 4 is arranged inside the lifting slot 11, a racket head 1 is fixedly installed on the upper end of the support rod 4, a rotating frame 6 is fixedly installed on the upper end of the handle 2, a positioning member 5 is rotatably arranged inside the rotating frame 6, a limiting clamp 12 is fixedly installed on the inner cavity side wall of the positioning member 5, and an adjusting slot 13 is arranged on the side of the support rod 4 at a corresponding position of the positioning member 5;

[0027] The lower end of the support rod 4 is fixedly mounted with a connecting rod 401, the lower end of the connecting rod 401 is fixedly mounted with a lifting rod 9, and the lower end of the positioning member 5 is rotatably provided with an adjusting rotary member 3;

[0028] A square slot is provided on the side wall of the rotating frame 6, and the rotating frame 6 and the positioning member 5 are connected by clamping and rotating. An anti-slip net is provided on the side of the positioning member 5, and the operator can rotate the positioning member 5 from the square slot position of the rotating frame 6, thereby controlling the rotation angle of the limit clamp 12;

[0029] The adjustment slot 13 is a downward stepped slot, and the depth of the adjustment slot 13 matches the length of the limit card 12. The limit card 12 can limit the position of the adjustment slot 13. When the limit card 12 is in the adjustment slot 13 with different step heights, the operator can make fine adjustments within the limited range of the adjustment slot 13, so that the overall badminton racket can be adjusted more accurately.

[0030] A limit member 8 is fixedly mounted in an annular manner on the upper end of the adjusting rotary member 3, and a rotation groove 7 corresponding to the limit member 8 is provided on the lower end of the adjusting rotary member 3. The adjusting rotary member 3 can rotate at the bottom of the handle 2 without being separated from the handle 2.

[0031] An adjusting thread groove 301 is provided in the middle of the adjusting rotary member 3, and a thread groove corresponding to the adjusting thread groove 301 is provided on the lower outer wall of the lifting rod 9. By rotating the adjusting rotary member 3, the internal adjusting thread groove 301 can be driven to rotate synchronously.

[0032] A support spring 10 is mounted on the outer side of the lifting rod 9, the upper end of the support spring 10 is fixedly connected to the bottom of the connecting rod 401, and the lower end of the support spring 10 is fixedly connected to the bottom of the inner cavity of the lifting groove 11. The support spring 10 can ensure that the connecting rod 401 remains stable during the adjustment process to avoid the lifting rod 9 and the adjusting threaded groove 301 from slipping after long-term use, causing shaking between the components.

[0033] The working principle of the utility model is as follows: the limit clamp 12 on the rear side of the positioning member 5 is inserted into the inside of the adjustment groove 13, the adjustment groove 13 is a downward stepped groove, and the depth of the adjustment groove 13 matches the length of the limit clamp 12. The outer side of the lower end of the lifting rod 9 is provided with a thread corresponding to the adjustment thread groove 301. When the adjustment rotary member 3 is rotated, the lifting rod 9 can be adjusted to move up and down. Since the upper end of the lifting rod 9 is fixedly installed with a connecting rod 401, and the upper end of the connecting rod 401 is fixedly installed with a supporting rod 4, when the lifting rod 9 moves up and down, the racket head 1 and the handle 2 can be adjusted. The distance between the racket head 1 and the handle 2 is adjusted. At this time, the limit card 12 can only be moved up and down within the limited position of one step of the adjustment slot 13 to prevent the operator from adjusting the distance between the racket head 1 and the handle 2 by too large an adjustment range, which causes a change in the hand feel. When the distance between the racket head 1 and the handle 2 needs to be adjusted significantly, first rotate the adjusting rotary member 3 until it cannot be rotated, and then adjust the rotating positioning member 5. The limit card 12 can be rotated from one step of the adjustment slot 13 to the next step. At this time, the adjusting rotary member 3 can continue to be rotated to control the lifting and lowering of the lifting rod 9 to change the overall length.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model.
