A rotating wheel 7 is fixedly installed at the other end of the bidirectional lead screw 6. The bottom surfaces of two symmetrically arranged slide seats 8 are slidably connected to the inner bottom surface of the fixing frame 2, and the bidirectional lead screw 6 penetrates through the slide seat 8 and is threadedly connected to the slide seat 8. The top surfaces of two symmetrically arranged slide blocks 9 are slidably connected to the bottom surface of the signboard 3. The upper end of a connecting rod 10 is rotatably connected to the slide block 9, and the lower end of the connecting rod 10 is rotatably connected to the slide seat 8. There are 2 connecting rods 10, and the middle parts of the 2 connecting rods 10 are hinged. By rotating the rotating wheel 7, the bidirectional lead screw 6 rotates, so that the two slide seats 8 threadedly connected to the bidirectional lead screw 6 move in opposite directions, and thus the signboard 3 moves through the action of the connecting rod 10 and the slide block 9, realizing the adjustment of the height of the signboard 3;

[0045] One end of a worm 11 is connected to the inner wall surface of one side of the housing 4 by a bearing, and the worm 11 penetrates through the other side wall of the housing 4 and is connected to the other side wall of the housing 4 by a bearing. A knob 12 is fixedly installed at the other end of the worm 11. The rear end of a rotating shaft 13 is connected to the rear inner wall of the housing 4 by a bearing. A worm gear 14 is fixedly sleeved on the rotating shaft 13, and the worm gear 14 is meshed with the worm 11. By rotating the knob 12, the worm 11 rotates, so that the worm gear 14 meshed with the worm 11 drives the rotating shaft 13 to rotate;

[0046] The shaft end of the transmission shaft 15 is connected to the inner wall of the housing 4 through a bearing. The gear set 16 is installed on the transmission shaft 15, and the front end of the rotating shaft 13 is connected to the gear set 16. Two symmetrically arranged support rods 17 are fixedly sleeved on the transmission shaft 15, and the support rods 17 penetrate through the through groove 5.

Then, the bottom surface of the substrate 1 and the bottom ends of the support rods 17 are placed on the ground. At this time, a triangular structure is formed among the substrate 1, the support rods 17, and the ground, ensuring the stable support of the support rods 17 for the substrate 1. At the same time, due to the change in the rotation angle of the support rods 17, the placement angle of the substrate 1 can be adjusted, so that the placement angle of the sign 3 can be adjusted, making it suitable for use in different sites and ensuring the effective indication function of the sign 3.
