Referring to fig. 10 and 11, it can be understood that a plurality of locking members 132 are disposed around the periphery of the guiding member 430, and the outer peripheral wall of the guiding member 430 is positioned and matched with the inner wall of the locking member 132 facing the end of the rod 410. The locking piece 132 can be spacing to the circumference of guide 430, can effectively reduce guide 430 and take place the drunkenness, improves the gliding stability of cock stem 400, and then makes guide 430 more stable to the direction of rotating piece 440, makes switch structure's operation more stable.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
