[0028] In the embodiment of the utility model, the second motor 8 is started, and the starting of the second motor 8 can drive the rotating rod 9 to rotate. Since the detection gear 10 is fixedly connected to the rotating rod 9, the starting of the second motor 8 can drive the detection gear 10 to rotate.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 The top of the working box 2 is fixedly connected to the display screen 13, and the inner cavity of the working box 2 is provided with heat dissipation holes 14, which are provided in multiple groups and distributed in a rectangular array.

[0032] In the embodiment of the utility model, starting the third motor 17 can drive the rotating shaft 18 to rotate. Since the first gear 19 is fixedly connected to the rotating shaft 18, the first gear 19 will rotate with the rotation of the rotating shaft 18, and the first gear 19 and the second gear 21 are meshed with each other, so starting the third motor 17 can drive the second gear 21 to rotate.
