The two clamping rods 12 on the same support plate 11 are perpendicular to each other. Limiting sleeves 13 are fixedly connected to the outer walls of the clamping rods 12. A second support arm 14 is rotatably connected to the outer wall of the first support arm 5. The second support arm 14 is inserted and matched with the clamping rod 12. One end of the first spring 7 is fixedly connected to the first support arm 5, and the other end of the first spring 7 is fixedly connected to the slider 8. By realizing the expansion and locking of the first support arm 5 and the second support arm 14, this design makes the device more adaptable to different construction environments, and the size and shape of the support structure can be adjusted according to actual needs.

[0022] As Figure 1 ,Figure 2 and Figure 6 As shown in Figure 6 , two lifting plates 101 are rotatably connected to the outer wall of the installation frame 1. Two fixing frames 15 are fixedly connected to the outer walls of the two lifting plates 101. Connecting rods 16 are fixedly connected to the inner walls of the two fixing frames 15. Second springs 17 are sleeved on the circumferential outer walls of the two connecting rods 16. Connecting arms 18 are slidably connected to the circumferential outer walls of the two connecting rods 16. The ends of the two connecting rods 16 penetrate through the connecting arms 18 and are slidably connected thereto. One end of the second spring 17 is fixedly connected to the fixing frame 15, and the other end of the second spring 17 is fixedly connected to the connecting arm 18. Bottom plates 20 are fixedly connected to the bottoms of the two connecting arms 18. Positioning rods 19 are fixedly connected to the bottoms of the two bottom plates 20.

[0023] Working principle: When in use, operate the bidirectional threaded rod 10 to rotate it within the adjacent two sliding sleeves 9. Since the thread directions of the bidirectional threaded rod 10 are opposite, it will simultaneously push the two sliding sleeves 9 to move in opposite directions. At this time, the slider 8 will slide along the sliding rod 6, while compressing or stretching the first spring 7;

[0024] When the first arm 5 is unfolded to an appropriate angle, insert the upper clamping rod 12 into the preset hole of the second arm 14. When the first arm 5 and the second arm 14 are locked, the device can be stably supported;

By rotating the second arm 14 to the bottom of the installation frame 1, insert the end of the side clamping rod 12 into the preset hole of the second arm 14, which is convenient for folding and storing the device;

[0026] By flipping the lifting plate 101, make the bottom of the positioning rod 19 abut against the top of the limit block 21. During the process of flipping the lifting plate 101, make the positioning rod 19 slide along the top of the limit block 21 until the positioning rod 19 is clamped into the inside of the limit block 21, so as to be able to unfold the lifting plate 101. Slide the signboard 3 to a suitable height, and through the engagement of the convex teeth of the elastic clamping plate 4 and the tooth plate 2, the fixing of the signboard 3 is realized, so as to be able to adjust the height of the signboard 3;

[0027] When folded, by pulling the bottom plate 20 upward to drag the connecting arm 18 to slide along the connecting rod 16, the positioning rod 19 is removed from the inside of the limit block 21, so that the lifting plate 101 can be folded and stored.
