The fixed block 301 and the supporting block 3131 can ensure the stability of the installation and rotation of the cover 2. When the cover 2 is rotated, the cover 2 can protect the display screen 4 and the operation keys 5.

[0035] The working principle of the above embodiment is:

[0036] When the knob 305 is turned, the knob 305 drives the rotating rod 304 to rotate, the rotating rod 304 drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear meshing therewith to rotate, the driven bevel gear drives the threaded rod 303 to rotate, under the action of the thread thrust, the threaded rod 303 drives the movable block 308 to move upward, the movable block 308 drives the upper rotating groove 310 to move upward, when the upper rotating groove 310 is separated from the top of the shaft 311, the shaft 311 can be moved upward. 1 is disassembled, thereby disassembling the cover plate 2, which is convenient for replacing the cover plate 2. When installing the cover plate 2, the bottom of the shaft rod 311 is placed into the lower rotating groove 3132, and the top of the shaft rod 311 corresponds to the position of the upper rotating groove 310. Finally, the knob 305 is rotated in the opposite direction. According to the above principle, the upper rotating groove 310 can be moved downward. When the top of the shaft rod 311 enters the upper rotating groove 310, the shaft rod 311 can be limited to ensure the stability of the rotation of the shaft rod 311, thereby ensuring the stability of the cover plate 2.
