[0081] Optionally, the first end surface 321 is provided with a third groove 327 , and the third groove 327 connects the first groove 324 and the center hole 325 , so that when assembling the elastic member 32 , there is no need to distinguish the assembly direction of the elastic member 32 , thereby improving the production speed and facilitating automated assembly.

[0082] A second groove 326 is provided on the second end surface 322, and the second groove 326 is connected to the first groove 324 and the center hole 325, so that the air in the center hole 325 can flow from the second groove 326 and the first groove 324 to the receiving space 11 at the insertion end 21 due to compression or thermal expansion, so that the deformation of the elastic member 32 is not hindered.

[0083] Please refer to Figure 3 There are multiple first grooves 324 and multiple second grooves 326 , and the multiple first grooves 324 are arranged at equal intervals on the first outer peripheral surface 323 , and the multiple second grooves 326 are arranged one-to-one corresponding to the multiple first grooves 324 .

[0084] Optionally, the number of the first grooves 324 may be 2-6, specifically 2, 3, 4, 5 and 6, etc., without limitation. Optionally, the number of the second grooves 326 and the third grooves 327 corresponds to the number of the first grooves 324, which will not be described in detail.

[0085] By providing a plurality of first grooves 324 and second grooves 326, the plurality of first grooves 324 are arranged at equal intervals on the first outer peripheral surface 323, and the plurality of second grooves 326 are arranged one-to-one corresponding to the plurality of first grooves 324, so that the air circulation at the center hole 325 is smoother, and the deformation of the elastic member 32 is avoided due to the blockage of a single first groove 324 or the second groove 326, thereby ensuring the stability of the elastic member 32, so that the elastic deformation of the elastic member 32 is not restricted, thereby slowing down the moving speed of the rotating shaft 20 and allowing the rotating shaft 20 to move quickly.
