[0043] Insert one end of the display 52 into a wing plate 10. At this time, the display 52 is overlapped on the crossbeam frame 15. Then, turn the handle 13 to drive the bidirectional screw 12 to rotate clockwise. When the bidirectional screw 12 rotates clockwise, the two sliders 8 are driven to move toward each other along the guide groove 7. The sliders 8 pull the corresponding moving seats 9 to slide along the steel 1 until the other side of the display 52 slides into the other wing plate 10. When the display 52 is tightly clamped between the two wing plates 10, the brake screw 19 is screwed down. The brake screw 19 is clamped on the rubber pad 17 to brake the movable seat 9, that is, to prevent the two wing plates 10 from loosening during the process of clamping the display 52; it should be noted that when the display 52 needs to be removed from between the two wing plates 10, the rubber pad ring 29 is first loosened. After the rubber pad ring 29 no longer clamps the adjusting screw 27, the handle 13 is turned to drive the bidirectional screw 12 to rotate counterclockwise, so that the bidirectional screw 12 drives the two sliders 8 to move back to back, and the distance between the two wing plates 10 becomes larger, and the display 52 is no longer clamped.

[0044] Embodiment 4, refer to the attached Figures 14 to 16 As shown, on the basis of the third embodiment, in order to achieve anti-sway limiting of the display 52 inserted into the wing plate 10, a rubber sleeve 20 is fixed to the inner ring surface of the wing plate 10, and the rubber sleeve 20 is clamped between the wing plate 10 and the display 52. ​​A reserved opening 21 is provided on one side plate of the wing plate 10, and the reserved opening 21 is in a "convex" shape. A sealing plate 22 is fixed in a notch at one end of the reserved opening 21, and an elastic band 23 is fixed in a notch at the other end of the reserved opening 21.

[0045] When the frame thickness of the display 52 is less than the spacing between the two parallel distribution plates of the wing plate 10, the screw handle 28 is turned to drive the adjusting screw 27 to rotate, and the adjusting screw 27 is limited by the limiting ring 31, that is, the adjusting screw 27 can only rotate on the surface of the sealing plate 22, and the adjusting screw 27 cannot achieve translation. When the adjusting screw 27 is driven to rotate clockwise, the adjusting screw 27 cooperates with the wire sleeve 26 to drive the clamping plate 24 to move along the reserved opening 21 toward the inner side of the wing plate 10. In this process, the clamping plate 24 tensions the elastic band 23 to produce elastic deformation until the elastic band 23 is clamped between the clamping plate 24 and the display 52. At this time, the hand screw 30 is turned to clamp the rubber gasket 29 to brake the screw handle 28, so that the clamping plate 24 stably clamps the display 52 inside the wing plate 10 to avoid the display 52 from shaking in the wing plate 10; when the display 52 needs to be removed, before adjusting the distance between the two wing plates 10, it is necessary to first loosen the hand screw 30 to no longer clamp the rubber gasket 29, and then rotate the adjusting screw 27 counterclockwise.

The pulley 39 is sleeved on the rod bodies of the limiting shafts 38; Embedding grooves 40 are formed in the top surfaces of the two parallel side plates of the lifting frame 37. A rubber clamping block 41 is fixed to the bottom surface of the embedding groove 40. The top surface of the rubber clamping block 41 is fixed to the outer wall of the sliding frame 33. The rubber clamping block 41 constitutes an elastic traction structure between the sliding frame 33 and the lifting frame 37. When the lifting frame 37 descends, the rubber clamping block 41 is tensioned to generate elastic deformation, and the rubber clamping block 41 rebounds to traction the lifting frame 37 to drive the second wire sleeve 36 and the threaded part of the second adjusting screw 42 to be firmly connected.

[0047] It should be noted that when the display 52 is installed and the display device needs to be placed stably, the support plate 3 is placed on the ground. At this time, the pulley 39 is suspended. When the display 52 needs to be moved on site, hold the handle 53 with one hand. The handle 53 is fixed to the surface of the wing plate 10. Hold the handle 53 tightly with one hand and lift one end of the profiled steel 1. At this time, the profiled steel 1 is inclined to the ground, and the support plate 3 at the lifted end of the profiled steel 1 is suspended. Use the other hand to turn the limiting handle 43 clockwise. When the limiting handle 43 rotates, it cooperates with the second wire sleeve 36 to push the lifting frame 37 downward. The lifting frame 37 slides down along the sliding seat 33 until the retaining ring 44 is blocked by the stepped plate of the sliding seat 33. At this time, slowly place the lifted profiled steel 1 on the ground. At this time, the support plate 3 is suspended, and the pulley 39 contacts the ground; in this way, the pulley 39 at the other end of the profiled steel 1 is adjusted to support the ground, and the support plate 3 is suspended, facilitating the sliding transfer of the display device; when the display device needs to be placed stably on the ground, rotate the limiting handle 43 counterclockwise to drive the lifting frame 37 to rise until the pulley 39 is suspended.

After the waterproof cover 48 is rolled up with the traction handle 49 as the central axis, the traction handle 49 is inserted between the elastic hanging plate 51 and the side plate of the cover plate 45 for limiting the position.

[0049] The reason for installing a cover plate 45 on the top of the wing plate 10 is to prevent dust from adhering to the surface of the display 52 and to prevent the display 52 from being soaked by water when the display decoration is idle for a long time. When installing the cover plate 45, buckle the cover plate 45 on the top of the two wing plates 10 at the same time, and then pass the bolt 2 47 through the two parallel ear plates 46 and lock them. As the bolt 2 47 is locked, the ear plates 46 pull the two side plates of the cover plate 45 closer, and the two side plates of the cover plate 45 clamp the wing plate 10 to prevent the cover plate 45 from falling off the top of the wing plate 10. Then unfold the waterproof cover 48 and push the traction handle 49 between the elastic enclosure 50 and the movable seat 9. At this time, the traction handle 49 is limited, and the waterproof cover 48 is unfolded to cover one side of the connecting sleeve 2, so that the remaining waterproof cover 48 is also unfolded.
