A control transmission line 408 is electrically connected to one side of the folding support foot 407.

[0031] The lifting support rod 403 and the lifting support base 401 form a sliding structure through the support rod lifting groove 402, and the lifting support base 401 and the limiting ring 405 form a threaded detachable structure through the limiting thread groove 404; the folding support foot 407 and the lifting support base 401 form a rotating structure through the support foot contraction groove 406, and the folding support foot 407 and the lifting support base 401 form a clamping structure through the limiting ring 405; the stability of the support is enhanced by the folding support foot 407 at the bottom. The limiting ring 405 is lifted upward along the lifting support base 401, and the folding support foot 407 rotates out of the support foot contraction groove 406. After rotating to an appropriate angle, the limiting ring 405 acts on the part of the limiting thread groove 404 on the outer wall of the lifting support base 401, and then is adjusted to a more stable support angle. After adjusting to a more stable support angle, the control transmission line 408 is connected to devices such as a camera, facilitating the automatic adjustment of the device during subsequent shooting to meet the shooting requirements, and the internal lifting support rod 403 moves up and down along the support rod lifting groove 402.

[0032] Working principle: First, the photographic background cloth support connecting block 1 and the overall position are fixed through the support support adjustment component 4. The stability of the support is enhanced by the folding support foot 407 at the bottom. The limiting ring 405 is lifted upward along the lifting support base 401, and then the folding support foot 407 rotates out of the support foot contraction groove 406. After rotating to an appropriate angle, the limiting ring 405 acts on the part of the limiting thread groove 404 on the outer wall of the lifting support base 401, and then is adjusted to a more stable support angle. Then, the control transmission line 408 is connected to devices such as a camera, facilitating the automatic adjustment of the device during subsequent shooting to meet the shooting requirements; the internal lifting support rod 403 moves up and down along the support rod lifting groove 402, driving the upper support adjustment component 2 and the background cloth component 3 to adjust the height. After the support support adjustment component 4 is fixed, it is adjusted through the support adjustment component 2. The support energy adjustment device 201 of the support controls the movement of the surrounding background cloth fixing frames 204. The background cloth fixing frames 204 move synchronously along the support adjustment grooves 203 in the support adjustment frames 202 to adapt to the shooting range. The support rotating block 205 at the bottom of the support energy adjustment device 201 rotates along the support rotating groove 206 in the bottom rotating device 207 to adjust a better shooting angle, and then select better lighting and other adjustments;

[0033] Secondly, the background cloth can be adjusted through the background cloth component 3 to obtain better shooting conditions. The bottom of the background cloth adjusting device 301 is provided with lamps that can adjust the color, light and darkness, which can adjust the shooting environment. The background cloth adjusting device 301 is clamped and fixed through the fixing strip at the top with the fixing clamping claw 306 and the retracting and adjusting device 308. An adjusting device fixing pad 305 is arranged between the fixing clamping claw 306 and the retracting and adjusting device 308, which can improve the overall service life of the device and increase the friction to strengthen the fixing effect on the internal background cloth adjusting device 301. The shaft on one side of the fixing clamping claw 306 adjusts the tightness of the fixing along the clamping adjusting groove 307 through hydraulic pressure, so as to perform operations such as clamping or loosening. The background cloth retracting and releasing device 303 is installed in the retracting device engaging groove 302 inside the background cloth adjusting device 301. The background cloth retracting and releasing device 303 can retract or release the adjustable background cloth 304, so as to adjust the size and length to better meet the shooting requirements.
