[0002] A camera crane is a special machine for photography that can be raised and lowered and moved during shooting. It is mainly composed of a base with wheels and a cantilevered lifting arm. When shooting on a camera crane, you can get a bird's-eye view of the whole picture, and continuously switch between medium and close-up pictures.

[0003] With the continuous development of automation technology, the base part can be replaced by an automatic camera track car, and the suspended lifting arm can be replaced by an automatic pan-tilt head, and the height of the pan-tilt head needs to be adjusted by a lift during shooting.

[0004] Most of the existing automatic lifts use screw transmission or hydraulic transmission, but the filming equipment on the workbench requires an external cable to communicate with the background. Since the workbench may be raised and lowered at any time, it is easy to tear the cable and cause signal interruption. Therefore, this application is proposed to solve this problem.

[0015] A workbench is fixedly arranged on the top of the telescopic shell, and the workbench is connected with the hollow lead screw through an internal threaded tube.

[0016] Furthermore, the lifting platform is made of magnesium-aluminum alloy, and the surface is passivated.

[0017] Furthermore, the power machine is a servo motor or a stepper motor.

[0018] Furthermore, the transmission device comprises:

[0019] The driving wheel has a first guide hole at the center, and the first guide hole is coaxially connected to the main shaft of the power machine and communicated with the main shaft of the power machine;
