[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1 - 4 , an embodiment provided by the present utility model: including a mounting base 1, a placing groove 2 is opened inside the mounting base 1, a moving plate 3 is arranged inside the placing groove 2, a right and left hand screw 4 is rotatably installed on the top of the moving plate 3, the top of the right and left hand screw 4 penetrates to the top of the mounting base 1, a moving assembly 5 for driving the moving plate 3 to move inward or outward simultaneously is arranged inside the placing groove 2, four groups of hooks 6 are arranged inside the right and left hand screw 4, and an adjusting assembly 7 for adjusting the distance between the hooks 6 is arranged on the surface of the right and left hand screw 4. First, the billboard can be hung on the hooks 6, then at this time, the moving assembly 5 can tighten the billboard left and right, and then the adjusting assembly 7 can tighten the vertical distance of the billboard, so as to be applicable to the installation of billboards of different sizes.

[0030] Refer to Figures 1 - 4, the moving component 5 includes a gear 51. The bottom of the inner wall of the placement groove 2 is fixedly installed with a motor 52. The output end of the motor 52 and the bottom of the gear 51 are fixedly installed. Two groups of toothed plates 53 are arranged inside the placement groove 2. The toothed plates 53 are engaged with the gear 51. The outside of the toothed plate 53 is fixedly installed with a connecting block 54. The outside of the connecting block 54 and the inside of the moving plate 3 are fixedly installed. Through the mutual cooperation of the gear 51, the motor 52, the toothed plate 53 and the connecting block 54, when the motor 52 is started, the gear 51 can be driven to rotate. The rotation of the gear 51 drives the toothed plates 53 to move inward or outward simultaneously, so that the distance between the two left - hand and right - hand threaded screws 4 can be adjusted according to the size of the billboard, and finally the billboard can be tightened and limited. The bottom of the toothed plate 53 is fixedly installed with a limiting block 8. The bottom of the inner wall of the placement groove 2 is provided with a limiting groove 9. The limiting block 8 and the limiting groove 9 are slidably installed. Through the mutual cooperation of the limiting block 8 and the limiting groove 9, the toothed plate 53 can be limited, preventing the toothed plate 53 from disengaging from the gear 51 during movement, resulting in the toothed plate 53 being unable to continuously engage with the gear 51, and thus unable to effectively drive the left - hand and right - hand threaded screws 4 to move.

[0031] Referring to Figures 1 - 4 , the adjusting component 7 includes four sets of screw blocks 71. Every two sets of screw blocks 71 are threadedly installed on the surface of a left - hand and right - hand threaded screw 4. The front side of the screw block 71 is provided with a rotating block 72. The inside of the rotating block 72 and the outside of the hook 6 are fixedly installed. Through the mutual cooperation of the screw block 71 and the rotating block 72, when the left - hand and right - hand threaded screw 4 is rotated, the screw block 71 and the hook 6 can be driven to move inward or outward simultaneously, so that the distance between the screw blocks 71 can be adjusted, and thus the distance between the hooks 6 can be adjusted according to the size of the billboard. The front side of the rotating block 72 is provided with a bolt 73. The back of the bolt 73 penetrates into the inside of the screw block 71. The screw blocks 71 are all threadedly installed with the screw block 71 and the rotating block 72. Through the setting of the bolt 73, the rotating block 72 can be rotated. When the rotating block 72 is rotated to an appropriate angle, the bolt 73 can be inserted into the rotating block 72 and the inside of the screw block 71 at this time, so as to realize the angle adjustment of the rotating block 72. The back of the screw block 71 is fixedly installed with a limiting frame 74. The top of the installation base 1 is provided with two sets of limiting plates 75. The limiting plates 75 and the limiting frame 74 are slidably installed. Through the mutual cooperation of the limiting frame 74 and the limiting plates 75, when the left - hand and right - hand threaded screw 4 and the screw block 71 move, the limiting frame 74 can not only limit the moving distance of the left - hand and right - hand threaded screw 4 left and right, but also prevent the screw block 71 from being affected by the rotational force of the left - hand and right - hand threaded screw 4 during movement. The outside of the limiting plate 75 is fixedly installed with a baffle 76. The inside of the baffle 76 and the outside of the limiting frame 74 are in contact. Through the setting of the baffle 76, the limiting plate 75 can be limited, preventing the left - hand and right - hand threaded screw 4 from driving the limiting plate 75 and the limiting frame 74 to disengage when moving left and right, resulting in the limiting plate 75 being unable to continue to limit the left - hand and right - hand threaded screw 4.

[0032] Working principle: First, the billboard can be hung on the hook 6, and then the motor 52 is started to drive the gear 51 to rotate. The rotation of the gear 51 drives the toothed plate 53 to move inward or outward at the same time. The movement of the toothed plate 53 drives the moving plate 3 and the left-right threaded screw 4 to move outward. The movement of the left-right threaded screw 4 drives the limit plate 75 to move, so that the distance between the two groups of left-right threaded screws 4 can be adjusted according to the size of the billboard. Finally, the left and right sides of the billboard can be tightened and limited. Then, rotate the rotating block 72. When the rotating block 72 rotates to an appropriate angle, the bolt 73 can be inserted into the rotating block 72 and the screw block 71 to realize the angle adjustment of the rotating block 72. Then, rotate the left-right threaded screw 4. The rotation of the left-right threaded screw 4 drives the screw block 71 and the hook 6 to move inward or outward at the same time, so that the distance between the screw blocks 71 of different sizes can be adjusted, so as to adapt to the installation of billboards of different sizes.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
