[0066] By converting the swing of the rocker arm 232 into the linear motion of the connecting rod 233, the stable sliding drive of the fixed housing 22 is realized, which not only simplifies the mechanical structure, but also improves the transmission efficiency and ensures the stability of the fixed housing 22 during the sliding process.

[0067] In one embodiment, a slideway 221 is provided on one side of the fixed housing 22 close to the upper cover 12, and the other end of the connecting component sequentially passes through the through hole 121 and the slideway 221; when the fixed housing 22 moves under the drive of the sliding structure 23, the connecting component is adapted to slide in the slideway 221.

[0068] Through the arrangement of the slideway 221, when the fixed shell 22 switches between the first fixed position and the second fixed position, it is convenient to realize the relative sliding between the connection component and the fixed shell 22, avoiding interference between the connection component and the fixed shell 22, and ensuring the smooth operation of the system.

[0069] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
