[0035] Working principle:

[0036] First, the position and height of the shooting frame are determined according to the shooting requirements. Then, the shooting frame is moved to a suitable position by controlling the walking wheel 12. Next, the rotation of the screw rod 22 is controlled by the brake wheel 23, thereby adjusting the height of the movable plate 21 so that it contacts the ground and increases the stability of the shooting frame.

[0037] Then, according to the height and angle requirements of the camera or other shooting equipment, the approximate height of the mounting assembly 5 is determined by adjusting the sliding position of the sleeve 4 on the column 3. Next, by turning the rotating wheel 55, the bidirectional threaded rod 54 is rotated, and the positions of the two sets of clamping plates 53 are adjusted so that the equipment can be tightly clamped.

[0038] Finally, by adjusting the position of the limiting assembly 6, the positioning pin 65 on the side wall of the pressure plate 62 is inserted into the positioning hole 41 and the insertion hole 31, so as to limit the height of the supporting plate 51 and prevent shaking or displacement during shooting.

[0039] During use, the position and height of the shooting frame can be adjusted at any time according to shooting requirements, and the stability of the shooting frame during fixed shooting can be ensured by controlling the height of the movable plate 21 and the limiting function of the limiting component 6. At the same time, since the shooting frame has walking wheels 12, it is easy to move and adjust, which provides great convenience for shooting.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
