[0033] The working principle of a multifunctional LED advertising screen provided by the utility model is as follows: by setting the adjustment structure 4, first observe the shape of the support rod 3, when the surface of the support rod 3 is in an arc shape, rotate the limit rod 409, and the limit rod 409 moves along the limit frame 407 toward the direction away from the clamping plate 408 with the help of the thread, after the limit rod 409 completely slides out of the limit hole 410, release the limit on the clamping plate 408, rotate the clamping plate 408 to 180° along the arc surface of the limit frame 407, so that the side with the reserved groove 55 on the clamping plate 408 is rotated to the clamping surface position, and then rotate the limit rod 409 in the opposite direction, and the limit rod 409 moves toward the direction close to the clamping plate 408 with the help of the thread and slides into the corresponding limit hole 410, so that the rotation angle of the clamping plate 408 is fixed, and after adjusting the clamping surfaces of the two clamping plates 408, The operating frame 1 is close to the support rod 3 so that the support rod 3 is located between the two clamping plates 408, and the bidirectional screw 403 is rotated. The bidirectional screw 403 drives the two movable plates 404 to move along the inner wall of the adjusting frame 402 with the help of the thread. The two movable plates 404 move towards each other at the same time, and the movable plates 404 drive the clamping plates 408 to move until the two clamping plates 408 are tightly against the surface of the support rod 3. Among them, the movable plates 404 are further limited by the sliding rod 405, so that the movable plates 404 are more stable when moving along the adjusting frame 402, and the friction between the inner wall of the adjusting frame 402 and the movable plates 404 is reduced by the pulley 406, so that the movable plates 404 are smoother when moving along the adjusting frame 402, and the friction on the surface of the clamping plates 408 is increased by the anti-slip pad 412, so that the limiting effect of the clamping plates 408 is better.

[0034] By setting the auxiliary structure 5, the auxiliary rod 54 is first rotated to 90° in the direction away from the frame 1. During this process, the auxiliary rod 54 drives the disk 52 to rotate along the round rod 51, and the coil spring 53 always gives the disk 52 a torsional force. Then, the excess length of the connecting line is wound around the auxiliary rod 54, and then the auxiliary rod 54 is loosened. At this time, the disk 52 is reset under the action of the torsional force of the coil spring 53, and the disk 52 drives the auxiliary rod 54 to rotate in the opposite direction to reset. Among them, the auxiliary rod 54 has a better limiting effect on the connecting line through the reserved groove 55. After the disk 52 rotates 90°, the positioning frame 56 is slid in the direction close to the round rod 51, so that the cylindrical part of the positioning frame 56 slides into the positioning hole 57, and the disk 52 is temporarily limited, which is convenient for the user to wind the connecting line.

[0035] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
