The rotating part 310 is capable of pitching and swinging around the rotating shaft 330, that is, the rotating part 310 rotates around the rotating shaft 330 relative to the base 100 (the first lug 110 or the second lug 120). The rotating part 310 has a first face 311 and a second face 312 oppositely arranged along the axial direction of the rotating shaft 330, the first face 311 is opposite to the inner side wall of the first lug 110, one of the first face 311 and the inner side wall of the first lug 110 is provided with a bump bead 313, and the other is provided with a plurality of bead holes 111 surrounding the rotating shaft 330, the end of the bump bead 313 can be limited in any bead hole 111 Figure 6In the process of the pitching swing of the rotating part 310, the bumping bead 313 jumps between any two adjacent bead holes 111 to enhance the rotating feeling of the user. Here, the top end of the bumping bead 313 is elastically connected to the main body, and the top end of the bumping bead 313 can elastically move along the depth direction of the bead hole 111 (i.e., the axial direction of the rotating shaft 330), so as to realize the jumping of the bumping bead 313 between the adjacent two bead holes 111. The bumping bead 313 and the bead hole 111 are a matching structure, and the positions and numbers of the two are replaced with each other, which can also achieve the same functional effect.

[0045] Further, in the present application, reference is made to Figures 4-6 Further, the support frame 10 includes a limiting disc 400 for limiting the pitching swing of the rotating part 310, so that the holder 300 is stably stopped at a target swing angle position.

Specifically, the unlocking piece 500 is slidingly connected to the second lug 120 along the axial direction of the rotating shaft 330, and the unlocking piece 500 abuts against the fourth face 420 after penetrating the second lug 120. Pressing the unlocking piece 500 can drive the limiting disc 400 to synchronously move away from the second lug 120, the second tooth 430 is disengaged from the first tooth 121, so as to release the circumferential limitation of the second lug 120 and the rotating part 310, release the limitation of the pitching swing of the rotating part 310, and make the bumping bead 313 limited in one of the bead holes 111. Such a design makes the bumping bead 313 cooperate with the plurality of bead holes 111 around the rotating shaft 330 to increase the rotating feeling of the rotating part 310 in the process of the pitching swing.

Among them, the hooks 520 can move in and out of the second insertion hole 122 along the axial direction of the rotating shaft 330, and pressing the end cover 510 drives the hooks 520 to move synchronously to push the second meshing tooth 430 away from the first meshing tooth 121 to release the circumferential limiting of the rotating part 310 and the second lug 120.
