The outer wall of the telescopic rod 502 is fixedly connected with a rotating shaft 501. The outer wall of the rotating shaft 501 penetrates and is rotatably connected with the inner wall of the plate body 4, so that the telescopic rod 502 rotates along the inner wall of the plate body 4 through the rotating shaft 501. The outer wall of the rotating shaft 501 is fixedly connected with a wedge A503, so that the wedge A503 is driven to rotate and move simultaneously during the rotation of the rotating shaft 501. The outer wall of the wedge A503 is clamped with a wedge B504 to achieve the effect of clamping and fixing the wedge A503, so as to maintain the stability of the rotating shaft 501 and the telescopic rod 502 after rotation. The top of the wedge B504 is fixedly connected with a pull rod 506. When the pull rod 506 moves vertically along the top of the plate body 4, the wedge block B504 is driven to move at the same time. The outer wall of the pull rod 506 is slidably connected to the top of the plate body 4 to maintain the stability of the pull rod 506 during vertical movement. The outer wall of the wedge block B504 is fixedly connected to one end of the spring A505, and the other end of the spring A505 is fixedly connected to the top of the plate body 4. The wedge block B504 is always driven downward by the force of the spring A505, so that the wedge block B504 maintains a clamping and fixing effect with the wedge block A503. The bottom of the telescopic rod 502 is hinged to the outer wall of the propaganda board 3, so that when the telescopic rod 502 drives the propaganda board 3 to move vertically, the length of the telescopic rod 502 will be adaptively adjusted for telescopic adjustment.

[0034] Reference Figure 2-Figure 4 The bottom of the base 1 is fixedly connected with an outer rod 15, so that the base 1 provides a supporting and fixing effect for the outer rod 15, the inner wall of the outer rod 15 is slidably connected with the inner rod 7, and the outer wall of the inner rod 7 is kept to move vertically along the inner wall of the outer rod 15, the top of the inner rod 7 is fixedly connected with one end of the spring B14, and the other end of the spring B14 is fixedly connected with the inner wall of the outer rod 15, and the inner rod 7 is driven to move downward by the force of the spring B14, so that the inner rod 7 drives the friction plate 10 at the bottom to move vertically at the same time, the bottom of the inner rod 7 is fixedly connected with the friction plate 10, and the outer wall of the friction plate 10 is fixedly connected with the control plate 9, so that the friction plate 10 drives the control plate 9 to move at the same time, and the top of the base 1 is fixedly connected with the bracket 8, so that the base 1 provides a supporting and fixing effect for the bracket 8.

[0035] Reference Figure 5The bracket 8 is slidably connected with a control plate 9 so that the control plate 9 can move vertically along the bracket 8. The control plate 9 is slidably connected with a handle 11 so that the handle 11 can move laterally along one side of the outer wall of the control plate 9. The outer wall of the handle 11 is fixedly connected with a concave fixing plate 12 so that the handle 11 drives the concave fixing plate 12 to move laterally at the same time during the lateral movement. The outer wall of the concave fixing plate 12 penetrates and is slidably connected with the inner wall of the control plate 9 to maintain the stability of the concave fixing plate 12 during lateral movement. The outer wall of the concave fixing plate 12 is fixedly connected with one end of a spring C13, and the other end of the spring C13 is fixedly connected with the inner wall of the control plate 9, and through the force of the spring C13, the concave fixing plate 12 is driven to move outward, so that the concave fixing plate 12 maintains a plug-in fixing effect with the bracket 8. The outer wall of the concave fixing plate 12 is plugged with one side of the outer wall of the bracket 8, so as to achieve the effect of fixing the vertical position of the control plate 9 and the friction plate 10.

[0036] Working principle: When the mobile billboard needs to be used, the staff pushes the billboard 3 to move the device through the pulley 2 set at the bottom. After moving to the designated location, in order to ensure the stability of the billboard 3 during use, the staff can press the handle 11 to make the handle 11 move laterally along the inner wall of the control board 9, so that the concave fixing plate 12 is driven to move simultaneously during the lateral movement of the handle 11, so that the bottom of the concave fixing plate 12 is separated from the outer wall of the bracket 8, thereby releasing the fixing effect on the control board 9, and cooperating with the force of the spring B14 to drive the inner rod 7 downward, so that the inner rod 7 drives the friction plate 10 at the bottom to fit and fix with the ground, thereby achieving the effect of improving the stability of the billboard 3.

[0037] When the height of the propaganda board 3 needs to be adjusted, the staff steps on the telescopic rod 502 to make the telescopic rod 502 flip along the inner wall of the plate body 4 through the rotating shaft 501 set on the outer wall. At the same time, the bottom of the telescopic rod 502 drives the propaganda board 3 to move vertically, so that the inner wall of the propaganda board 3 moves vertically along the outer wall of the sliding column 6, and cooperates with the wedge block A503 set on the outer wall of the rotating shaft 501, so that the wedge block A503 passes through the wedge block B504 by squeezing, and at the same time, the force of the spring A505 drives the wedge block B504 to descend, so as to achieve the effect of clamping and fixing the wedge block A503, so that the height of the propaganda board 3 can be quickly adjusted by stepping on it, which saves effort and achieves the purpose of easy adjustment.
