AI Technical Summary
When adjusting the height of existing shooting brackets, the contact area with the ground remains unchanged, causing a shift in the center of gravity and reducing the overall stability of the bracket.
By employing expansion components and counterweight components, and through the cooperation of threaded rods and worm gears, the contact area of the support base is automatically adjusted, and the center of gravity is kept stable by the movement of the counterweight, ensuring that the support remains stable when the height changes.
During height adjustment, the contact area of the support base is automatically increased to keep the center of gravity constant, thereby improving the overall stability of the bracket, preventing tipping, and protecting the shooting equipment.
