[0029] An upper limit switch 410 and a lower limit switch 420 are provided on the wiring board 400. The connection lines of the upper limit switch 410 and the lower limit switch 420 are uniformly connected to the relevant control equipment through the wiring board 400, avoiding the problem that when the upper limit switch 410 and the lower limit switch 420 are set at different positions, the connection lines are connected to the relevant equipment from different positions, causing the connection lines to be entangled with each other during the flipping process.

[0030] An upper limit stopper 510 and a lower limit stopper 520 are provided on the disc 500 . When the rotating shaft 300 drives the disc 500 to rotate, the upper limit stopper 510 and the lower limit stopper 520 rotate along with the disc 500 .

[0031] The upper limit switch 410 and the upper limit block 510 are arranged in cooperation with each other. When the upper limit block 510 presses the upper limit switch 410, the upper limit signal of the upper limit switch 410 is disconnected, the motor stops rotating, and the flip frame 200 stops rotating upward; the lower limit switch 420 and the lower limit block 520 are arranged in cooperation with each other. When the lower limit block 520 presses the lower limit switch 420, the lower limit signal of the lower limit switch 420 is disconnected, the motor stops rotating, and the flip frame 200 stops rotating downward.

[0032] The disc 500 is provided with an upper limit groove 530 and a lower limit groove 540, and the upper limit groove 530 and the lower limit groove 540 are waist circles opened on the disc 500, and the waist circle is arc-shaped.

[0033] When the flip frame 200 flips upward due to the drive of the motor, the rotating shaft 300 drives the upper limit stopper 510 on the disk 500 to rotate together. When the upper limit stopper 510 presses the upper limit switch 410 during the rotation, the upper limit signal of the upper limit switch 410 is disconnected, the motor stops rotating, and the flip frame 200 stops rotating upward; when the flip frame 200 flips downward due to the drive of the motor, the rotating shaft 300 drives the lower limit stopper 520 on the disk 500 to rotate together. When the lower limit stopper 520 presses the lower limit switch 420 during the rotation, the lower limit signal of the lower limit switch 420 is disconnected, the motor stops rotating, and the flip frame 200 stops rotating downward.

[0034] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
