[0117] Step A, operate the rotary motor 9 to rotate, the rotary motor 9 rotates and drives the first gear 11-1 to rotate through the rotary reducer 2, the first gear 11-1 rotates and drives the second gear 11-2 to rotate, the second gear 11-2 rotates and drives the transmission shaft 11-3 to rotate, the transmission shaft 11-3 rotates and drives the third gear 11-4 to rotate, the third gear 11-4 rotates and drives the fourth gear 11-5 to rotate, the fourth gear 11-5 rotates and drives the connecting seat 12 to rotate through the connecting shaft 11-6, the connecting seat 12 rotates and drives the camera bed 1 to rotate until the camera bed 1 meets the use requirements; wherein, during the rotation of the camera bed 1, when the fifth proximity switch 14-2 outputs a low level signal, it means that the camera bed 1 rotates to +90°; when the sixth proximity switch outputs a low level signal, it means that the camera bed 1 rotates to -90;

[0118] Step B, after use, operate the rotating motor 9 to rotate in the reverse direction, the connection base 12 rotates to drive the camera bed 1 to rotate in the reverse direction, when the fourth proximity switch 14-1 detects the camera bed 1, it means that the camera bed 1 rotates to a horizontal 0°; wherein, when the fourth proximity switch 14-1 outputs a low level signal, it means that the camera bed 1 rotates to a horizontal 0°

[0119] When the camera bed 1 needs to be lowered, the specific process is as follows:

[0120] The lifting motor 3 is operated to work. The lifting motor 3 rotates in the reverse direction and drives the lifting gear 5-1 to rotate in the reverse direction through the lifting reducer 5. The lifting gear 5-1 slides and descends along the rack 5-2, driving the sliding plate 16-2 to descend along the guide rail 7 through the slider 16-1. The sliding plate 16-2 drives the camera bed 1 to descend through the mounting assembly 13 and the connecting seat 12. When the third proximity switch 20-3 detects the camera bed 1 during the descent of the camera bed 1, it indicates that the camera bed 1 has descended to the lowest position.

[0124] In this embodiment, the normal lifting speed of the camera bed 1 is no more than 36 mm / s.

[0125] In this embodiment, when the third proximity switch 20-3 detects the camera bed 1, it means that the camera bed 1 has dropped to the lowest position. At this time, the distance between the camera bed 1 and the base 20 can be reduced to 470 mm, so that the distance between the camera bed 1 and the ground can be reduced to 470 mm, which is convenient for patients to get on the camera bed, especially critically ill patients, disabled people, etc.

[0126] In this embodiment, in actual use, the second proximity switch 20 - 2 is arranged close to the first proximity switch 20 - 1 , and the height of the first proximity switch 20 - 1 is lower than 1 / 2 of the height of the stand mechanism 6 .
