[0026] Embodiment 2

[0027] See also Figures 1 to 9A rectangular through groove 5 is provided at the top of the support block 1, and a connecting plate 13 is slidably connected between the inner walls on both sides of the rectangular through groove 5. Two circular grooves 1 that are far away from each other and symmetrically distributed are provided at the bottom of the inner wall of the rectangular through groove 5. The inner walls of the two circular grooves are fixedly connected with hollow cylinders 7, and the inner wall of the hollow cylinder 7 is slidably connected with a spring 18. The outer walls of the two hollow cylinders 7 are slidably connected to the inside of the connecting plate 13, and the tops of the two springs 8 are fixedly connected to the inside of the connecting plate 13. A trapezoidal groove 12 is provided at the inclined end of the trapezoidal block three 11. The cross section of the trapezoidal groove 12 is a right-angled trapezoid and the height is equal to that of the spring 18. The cross section of the connecting plate 13 is an isosceles trapezoid. The cross sections of the trapezoidal block three 11, the trapezoidal block 3 and the side plate 24 are all right-angled trapezoids. Between the trapezoidal block three 11 and the inner wall of the transverse groove 9 Two symmetrically distributed springs 2 10 are fixedly connected, a side groove is opened on one side of the trapezoidal block 3 11, a rack 14 is fixedly connected inside the side groove, a gear 15 is rotatably connected inside the square groove 26, the outer wall of the rack 14 is meshed with the outer wall of the gear 15, the rack 2 16 and the bar block 23 are both slidably connected inside the sliding groove 20, a connecting groove 22 is opened and connected at the top of 20, a connecting plate 21 is slidably connected inside the connecting groove 22, one side of the side plate 24 is fixedly connected with three equidistantly arranged fastening blocks 25, the cross-section of the fastening block 25 is a regular hexagon, and the end of the fastening block 25 away from the side plate 24 is chamfered, and one side of another adjacent side plate 24 is opened with three equidistantly arranged regular hexagonal grooves, and the fastening block 25 is clamped with the inside of the regular hexagonal groove.

[0028] The height of the trapezoidal groove 12 is smaller than the trapezoidal block three 11. Before the installation of the advertising body 2, the receiving plate 6 is at the same height as the trapezoidal block one 3, and each spring one 8 and spring two 10 are in a state of being free of stress. It should be noted here that the gravity of the receiving plate 6 and the connecting plate one 13 is not enough to compress the spring one 8. The two trapezoidal blocks three 11 are close to each other but not in contact. The two hollow cylinders 7 are respectively present in the two trapezoidal grooves 12 at this time, and the outer wall of the hollow cylinder 7 is in a sliding connection with the inner wall of the trapezoidal groove 12. When the bottom end of the advertising body 2 is placed on the top of the receiving plate 6 of the two supporting devices, that is, when the installation operation begins, the receiving plate 6 and the connecting plate one 13 will produce a vertical downward displacement due to the gravity of the advertising body 2 itself. The inclined end of the connecting plate 13 contacts the inclined ends of the two trapezoidal blocks 3 11 and applies pressure, so that the two trapezoidal blocks 3 11 produce reverse displacement. Through the provided gear 15 and rack 1 14, the displacement of the trapezoidal block 3 11 will cause the gear 15 to rotate and drive the rack 2 16 to displace synchronously. Under the connection of the connecting plate 21, the two trapezoidal blocks 24 approach each other, and eventually the outer walls of both sides of the advertising body 2 will be stuck to prevent shaking. At the same time, under the connection of the bar block 23, the two side panels 24 approach each other, and eventually the two side panels 24 are fitted together, and each fastening block 25 is respectively snapped into the interior of each regular hexagonal groove to complete the protection of the two ends of the advertising body 2 and improve stability.

A plurality of rollers 18 arranged equidistantly are arranged inside the auxiliary part 17, and the outer wall of each roller 18 is rollingly connected with the inner wall of the auxiliary groove 19.

[0031] Each roller 18 will roll and displace on the inner wall of the auxiliary groove 19 synchronously with the displacement of the rack 2 16. By setting 71, the roller 18 and the auxiliary groove 19, part of the sliding friction is converted into rolling friction, which improves the smoothness of the displacement of the rack 2 16, indirectly making the entire installation process faster and helping to improve efficiency.

[0032] The working principle and use process of the utility model are as follows: at the beginning of the installation operation, the bottom end of the advertising body 2 is placed on the top of the receiving plate 6 of the two supporting devices. Under the gravity of the advertising body 2 itself, the receiving plate 6 and the connecting plate 13 will have a vertical downward displacement, and the inclined end of the connecting plate 13 and the inclined ends of the two trapezoidal blocks 11 contact each other and apply pressure, so that the two trapezoidal blocks 11 produce reverse displacement, and through the provided gear 15 and rack 14, the displacement of the trapezoidal block 11 will cause the gear 15 to rotate and The rack 2 16 is driven to displace synchronously. Under the connection of the connecting plate 21, the two trapezoidal blocks 24 are close to each other, and finally the outer walls of the two sides of the advertising body 2 are clamped to prevent shaking. At the same time, under the connection of the strip block 23, the two side panels 24 are close to each other, and finally the two side panels 24 are fitted together. Each fastening block 25 is respectively clamped into the inside of each regular hexagonal groove to complete the protection of the two ends of the advertising body 2 and improve stability. At this point, the installation is completed and the effect is stable, the operation is simple, and the installation efficiency is improved.
