The length expansion mechanism is arranged at the tail end of the top of the racket handle. The length expansion mechanism includes a sliding cavity, an end cap, a sliding rod, a threaded rod, a screw head, a threaded hole, and an extended handle sleeve. A sliding cavity is arranged in the middle of the top of the racket handle. The bottom end of the end cap is connected with a sliding rod, and the sliding rod is slidably sleeved inside the sliding cavity, so that the end cap is slidably connected to the racket handle. A threaded rod is rotatably installed at the bottom of the sliding rod. The top end of the threaded rod longitudinally penetrates through the sliding rod and the end cap. The top end of the threaded rod is integrally provided with a screw head, and the screw head is located at the top of the end cap. A threaded hole is opened in the middle of the bottom surface of the sliding cavity, and the threaded rod is threadedly connected to the inside of the threaded hole. An extended handle sleeve is nested outside the sliding rod, and the extended handle sleeve is tightly clamped between the racket handle and the end cap.

[0007] Preferably, both the sliding rod and the extended handle sleeve are made of the same material as the racket handle.

[0008] Preferably, the cross-sectional shape and size of the extension handle sleeve are the same as those of the sliding rod.

[0009] Preferably, the cross-section of the sliding rod is of a polygonal structure, and the inner cross-sections of the sliding cavity and the extension handle sleeve match the cross-sectional shape and size of the sliding rod.

[0010] Preferably, the length of the sliding rod is not less than 4 cm.

[0011] Preferably, the threaded rod is made of plastic.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, a length extension mechanism is provided at the tail end of the top of the racket handle. By sleeving the extension handle sleeve outside the sliding rod, then inserting the sliding rod back into the sliding cavity, making the threaded rod contact the threaded hole, and then using a screwdriver to rotate the screw head to control the threaded rod to rotate forward, the threaded rod is screwed into the threaded hole. During this process, the end cap will gradually move closer to the racket handle until the extension handle sleeve is firmly clamped between the racket handle and the end cap, thus completing the extended installation operation. The extension handle sleeve can be used as an additional length to further extend the racket handle, and the length of the racket handle can be adjusted by installing extension handle sleeves of different lengths, making the racket handle have better expandability.

[0019] In order to further explain the technical solution of the present utility model, the following is elaborated in detail through specific embodiments.

[0020] Please refer to Figure 1 , the present utility model provides a grip end cap for a badminton racket, including a racket handle 1 and a length extension mechanism 2, and a length extension mechanism 2 is provided at the tail end of the top of the racket handle 1.

[0021] Please refer to Figures 2 - 4 , the present utility model provides a grip end cap for a badminton racket. The length extension mechanism 2 includes a sliding cavity 21, an end cap 22, a sliding rod 23, a threaded rod 24, a screw head 25, a threaded hole 26, and an extended handle sleeve 27. A sliding cavity 21 is centrally provided at the top of the racket handle 1. The bottom end of the end cap 22 is connected to a sliding rod 23, and the sliding rod 23 is slidably sleeved inside the sliding cavity 21, so that the end cap 22 is slidably connected to the racket handle 1. A threaded rod 24 is rotatably installed at the bottom of the sliding rod 23. The top end of the threaded rod 24 longitudinally penetrates through the sliding rod 23 and the end cap 22. The top end of the threaded rod 24 is integrally provided with a screw head 25. The screw head 25 is located at the top of the end cap 22. A screwdriver can be used to turn the screw head 25 to control the rotation of the threaded rod 24. A threaded hole 26 is centrally opened at the bottom surface of the sliding cavity 21. The threaded rod 24 is threadedly connected to the inside of the threaded hole 26. An extended handle sleeve 27 is nested outside the sliding rod 23, and the extended handle sleeve 27 is tightly clamped between the racket handle 1 and the end cap 22. The extended handle sleeve 27 can be used as an additional length to further extend the racket handle 1. By installing extended handle sleeves 27 of different lengths, the length of the racket handle 1 can be adjusted, which has better expandability.

[0022] Furthermore, both the sliding rod 23 and the extended handle sleeve 27 are made of the same material as the racket handle 1, so that the material densities of the sliding rod 23, the extended handle sleeve 27, and the racket handle 1 are equal, ensuring the stability of the center of gravity of the racket handle 1 and guaranteeing the operability.

[0023] Furthermore, the cross-sectional shape and size of the extended handle sleeve 27 are the same as those of the sliding rod 23, ensuring that the extended handle sleeve 27 can be accurately aligned with the sliding rod 23 and having the same holding feel after winding the grip tape.

[0024] Furthermore, the cross-section of the sliding rod 23 is in a polygonal structure, and the inner cross-sections of the sliding cavity 21 and the extended handle sleeve 27 match the cross-sectional shape and size of the sliding rod 23, so that the rotation angle can be locked after the sliding rod 23 is sleeved with the sliding cavity 21 and the extended handle sleeve 27, ensuring the installation stability.

[0025] Furthermore, the length of the sliding rod 23 is not less than 4 cm, so that the length extension mechanism 2 has a sufficient extension range.

[0026] Furthermore, the threaded rod 24 is made of plastic material to better meet the lightweight requirement of the racket handle 1.

[0027] The working principle is as follows:

[0028] First, by providing the length extension mechanism 2 at the top end of the racket handle 1, when the length of the racket handle 1 needs to be extended, first use a screwdriver to turn the screw head 25 to control the reverse rotation of the threaded rod 24 until the threaded rod 24 is screwed out of the threaded hole 26, and then the sliding rod 23 can be slid out of the sliding cavity 21, separating the end cap 22 from the racket handle 1.

[0029] Second, select an extension handle sleeve 27 of appropriate length and fit it over the outside of the slide rod 23. Then insert the slide rod 23 back into the slide cavity 21 so that the threaded rod 24 contacts the threaded hole 26. Next, use a screwdriver to turn the screw head 25 to control the forward rotation of the threaded rod 24, causing the threaded rod 24 to be screwed into the threaded hole 26. During this process, the end cap 22 will gradually move closer to the racket handle 1 until the extension handle sleeve 27 is firmly clamped between the racket handle 1 and the end cap 22, thus completing the expansion installation operation. The extension handle sleeve 27 can further extend the racket handle 1 as an additional length, and the length of the racket handle 1 can be adjusted by installing extension handle sleeves 27 of different lengths, making the racket handle 1 have better expandability.

[0030] Third, if the user does not need the additional length of the extension handle sleeve 27, the extension handle sleeve 27 can be removed. Then insert the slide rod 23 back into the slide cavity 21, and control the threaded rod 24 to be screwed into the threaded hole 26 so that the end cap 22 directly abuts and fits tightly against the end of the racket handle 1 to complete the installation, which has good adaptability.

[0031] The above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
