AI Technical Summary

Technical Problem

When adjusting the height of the existing shooting support frame, the contact area between the support rod and the inner wall of the sleeve decreases, resulting in instability of the shooting frame and affecting the shooting effect of the camera.

Method used

It adopts a telescopic support assembly, including a telescopic rod, a telescopic cylinder, and a support cylinder, and achieves precise lifting and lowering through a first drive assembly and a lead screw. It is equipped with an adjusting arm and directional support wheels to increase stability; a movable mounting base and synchronous belt drive improve flexibility; a counterweight balances the weight, and casters facilitate movement.

Benefits of technology

Ensure the stability of the shooting rig at different heights and angles, improve shooting quality and analysis accuracy, meet diverse shooting needs, reduce the impact of shaking, and improve shooting efficiency.
