A side tension spring connects the corresponding U-shaped rods on both sides of the base plate. A top pull plate is provided at the top of the base plate, and a bottom pull plate is provided at the bottom. A U-shaped rod is provided on the top pull plate facing the base plate, penetrating the adjacent base plate side edge. A top tension spring is installed inside the U-shaped rod at the upper part of the base plate, with one end connected to the middle of the U-shaped rod and the other end fixed to the inner side of the bottom pull plate.

[0005] Preferably, a clamping plate is connected to the front side of the top pull plate, and the end of the clamping plate away from the card holder base plate is connected to the top pull plate by a spring hinge; a clamping plate is connected to the front side of the side pull plate, and the end of the clamping plate away from the card holder base plate is connected to the side pull plate by a spring hinge; a clamping plate is connected to the front side of the bottom pull plate, and the end of the clamping plate away from the card holder base plate is connected to the bottom pull plate by a spring hinge.

[0006] Preferably, a clamp is provided on the back of the card holder base plate, and the upper and lower ends of the clamp are fixedly connected to the sides of the base plate located on the upper and lower sides of the card holder base plate, respectively.

[0007] Compared with the prior art, this utility model has the following advantages and effects: reasonable structure, simple operation, can be adjusted according to different sizes of signs to realize the installation of signs, and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Example

[0016] like Figures 1-5 As shown, this embodiment includes a card holder base plate 1. A base plate side edge 2 is provided around the back of the base plate 1, surrounding it. Symmetrically arranged side pull plates 3 are installed on both sides of the base plate 1. A U-shaped rod 4 is provided on the side of the side pull plate 3 facing the base plate 1, penetrating the adjacent base plate side edge 2. A side tension spring 5 connects the corresponding U-shaped rods 4 on both sides of the base plate 1. Specifically, the side pull plates 3 on both sides of the base plate 1 can be pulled outwards. After release, the side pull plates 3 can move towards the base plate 1 under the action of the side tension spring 5 to achieve a reset.

[0017] like Figures 1-5 As shown, a top pull plate 6 is provided at the top of the card holder base plate 1, and a bottom pull plate 7 is provided at the bottom of the card holder base plate 1. A U-shaped rod 4 is provided on one side of the top pull plate 6, penetrating the side edge 2 adjacent to the base plate. A top tension spring 8 is provided inside the U-shaped rod 4 located at the upper part of the card holder base plate 1. One end of the top tension spring 8 is connected to the middle of the U-shaped rod 4, and the other end of the top tension spring 8 is fixed to the inner side of the bottom pull plate 7. Specifically, the top pull plate 6 located at the top of the card holder base plate 1 can be pulled outward. After releasing, the top pull plate 6 can move towards the card holder base plate 1 under the action of the top tension spring 8 to achieve reset.

[0018] like Figures 1-5 As shown, the top pull plate 6, side pull plate 3, and bottom pull plate 7 are all connected to a clamping plate 9 on their front sides. The end of the clamping plate 9 away from the plate holder base plate 1 is connected to the top pull plate 6, side pull plate 3, or bottom pull plate 7 via a spring hinge 10. Specifically, opening the clamping plate 9 allows the sign to be clamped from the side.

[0019] like Figure 1 , Figure 5As shown, a clamp 11 is provided on the back of the sign holder base plate 1. The upper and lower ends of the clamp 11 are fixedly connected to the base plate side 2 located on the upper and lower sides of the sign holder base plate 1, respectively. The clamp 11 can be used to fix the sign holder to the column.

[0020] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
