[0032] In this embodiment, the output end of the motor 106 drives the screw 107 to rotate forward. The screw 107 rotates forward and drives the slider 109 to move downward as a whole. The slider 109 moves downward and drives the connecting plate 110 to move downward as a whole. At this time, the limit column 108 limits the connecting plate 110 as a whole to prevent the connecting plate 110 from idling. The connecting plate 110 moves downward as a whole, driving the long rod 111 and the moving rod 112 to move downward as a whole.

[0035] Working principle: When in use, the staff turns on the external power supply of the motor 106, and uses the controller to start the motor 106. The output end of the motor 106 starts to drive the screw 107 to rotate forward. The screw 107 rotates forward and drives the slider 109 to move downward as a whole. The slider 109 moves downward and drives the connecting plate 110 to move downward as a whole. At this time, the limit column 108 limits the connecting plate 110 as a whole to prevent the connecting plate 110 from idling. The connecting plate 110 moves downward as a whole, and drives the long rod 111 and the moving rod 112 to move downward as a whole. The staff controls the forward and reverse rotation of the motor 106 to make the connecting plate 110 rise or fall as a whole, so as to achieve the lifting and lowering adjustment as needed, and the structure is simple, the manufacturing cost is low, and it is convenient It is suitable for doctors to use, which improves the usability of the medical pendant rotating arm power column. In order to better clamp the medical instruments, the staff places the medical instruments between the two splints 202, and then turns on the external power supply of the motor 114, and uses the controller to start the motor 114. The output end of the motor 114 starts to rotate forward and drives the gear 203 to rotate. The gear 203 drives the two racks 201 to move inward. As the gear 203 continues to rotate, the two racks 201 gradually move inward. When the two racks 201 move, the two splints 202 gradually clamp the medical instruments firmly, thereby facilitating the firm clamping of the medical instruments. When in use, it is prevented from slipping, thereby improving the working efficiency of the medical pendant rotating arm power column.
