[0047] The casing 10 comprises a shell 12 and a mounting frame 13 mounted in the shell 12, and the motor assembly 20 is slidingly mounted in the mounting frame 13. The mounting frame 13 and the shell 12 are separately arranged and assembled as a whole. The shell 12 is a tubular profile structure, and the mounting frame 13 is assembled into the shell 12 after the motor assembly 20 is mounted.

[0048] The knob assembly 30 penetrates the shell 12 and the mounting frame 13, and the sliding hole 11 penetrates one side wall of the shell 12.

The guide protrusions 221 are inserted into the guide portions 133 on both sides of the sliding cavity 132, so as to form a sliding fit and prevent the motor assembly 20 from being deflected in the circumferential direction.

[0058] In an embodiment, the mounting frame 13 includes a notch groove 134 intersecting at least part of the sliding cavity 132. The notch groove 134 extends from one end of the mounting frame 13 to the other end, and a lateral opening is formed at the intersection of the sliding cavity 132 and the notch groove 134. The lateral opening can form a flexible structure in the area of the mounting frame 13, so as to facilitate the sliding and mounting of the motor assembly 20.
