The lifting plate 2 is internally connected to a bidirectional screw rod 10 through a bearing. The bottom of the bidirectional screw rod 10 The end passes through the bearing to the outside of the lifting plate 2 and is fixed with a knob 9. The knob 9 drives the bidirectional screw rod 10 to rotate. The two sides of the bidirectional screw rod 10 are threaded with threaded plates 11 and the threaded connection directions are opposite. The front end of the threaded plate 11 slides through the outside of the lifting plate 2 and is fixed with a support rod 12. The front side of the lifting plate 2 is symmetrically provided with through grooves adapted to the threaded plate 11. The ends of the two groups of support rods 12 away from the threaded plate 11 are fixedly welded with sliding tubes 13. Both sides of the inside of the sliding tube 13 are slidably connected with sliding rods 14, so that the sliding rods 14 can slide and displace inside the sliding tube 13. The end of the rod 14 located outside the sliding tube 13 is fixed with a sign clamping mechanism for clamping the sign. The two-way screw rod 10 is driven to rotate by the knob 9, so that the threaded plates 11 on both sides of the two-way screw rod 10 drive two groups of support rods 12, and the support rods 12 drive the sliding tube 13 to move. At the same time, the sliding rods 14 are slidably connected on both sides of the sliding tube 13 and the sign clamping mechanism is fixed on the side of the sliding rod 14 located outside the sliding tube 13, so that the four groups of sign clamping mechanisms can be adjusted in position within a certain range, thereby facilitating the placement and fixation of signboards of different sizes.

[0022] The reminder sign clamping mechanism includes a concave clamping frame 15 and a fixed block 16, wherein the fixed block 16 is fixed between the clamping frame 15 and the sliding rod 14, and a latch 17 is slidably penetrated through the front side wall of the clamping frame 15, and the rear end of the latch 17 is located in the clamping frame 15 and fixed with a rubber pressure block 18, and a first limit spring 19 is fixed to the side of the rubber pressure block 18 away from the sliding rod 14, and the first limit spring 19 is slidably sleeved on the latch 17, and one end of the first limit spring 19 away from the rubber pressure block 18 is fixedly connected to the front inner wall of the clamping frame 15, and the first limit spring 19 provides elastic force for the rubber pressure block 18, so that the rubber pressure block 18 is pushed backward and cooperates with the inner wall of the clamping frame 15 to clamp the reminder sign, and the four groups of reminder sign clamping mechanisms clamp and fix the four corners of the reminder sign respectively.

[0023] A positioning bolt 20 is threaded through the side of the sliding tube 13 away from the support rod 12, and each group of sliding tubes 13 is provided with two groups of positioning bolts 20 threaded through, and the two groups of positioning bolts 20 are symmetrically distributed on the left and right.
