[0071] In order to improve the stability of assembly, the four side walls of the plate body 200 are each provided with a plug pin 100, and the corresponding frame body 300 is provided with four sockets 310.

[0072] When assembling: the four plug pins 100 are respectively inserted into the four side holes 210 of the plate body 200, and the second through hole 122 of the plug pin 100 is caused to correspond to the bottom hole 220, so that the hexagonal spoon can be connected with the driving piece 3; after the plug pin 100 is assembled, the pin head 211 extends out of the shell 1 under the action of the spring 4, and is in an extended state;

[0073] Then, one of the plug pins 100 is aligned with the socket of the frame body 300, and the pin head 211 is inserted into the socket 310, then the plate body 200 is turned downward, and when the remaining three plug pins 100 contact the frame body 300, the pin head 211 is retracted under the action of the frame body 300, when the pin head 211 corresponds to the socket, the pin head 211 is extended under the action of the spring 4 and is inserted into the socket 310, thereby completing the assembly. Of course, the pin head 211 can also be retracted in advance by the hexagonal spoon, when the pin head 211 corresponds to the socket 310, the external force is released, the pin head 211 is extended under the action of the spring 4 and is inserted into the socket 310. The assembly is convenient.

[0074] When disassembling, the driving piece 3 is driven to rotate by the hexagonal spoon, the plug pin 2 is pushed to retract, when the pin head 211 is separated from the socket 310, the plate body 200 can be separated from the frame body 300. The disassembly is convenient.

[0075] Optionally, referring to Figure 10 and Figure 11 , the socket 310 is a reserved hole structure, that is, the outline of the socket 310 has been punched, but not cut through, for example, half-punched or partially punched, etc., the punched waste piece 320 is reserved, when the plate body 200 needs to be assembled, or needs to be assembled by the plug pin 100, the waste piece 320 is removed by using a screwdriver or other tool, and then the assembly is performed. In this way, it is beneficial to protect the socket 310, and also prevents foreign matter from entering the inside of the frame body 300.

[0076] The display stand can be a multi-layer structure, and each plate body 200 of each layer can be assembled by the plug pin 100.

[0077] Of course, the plug pin 100 can also be used to assemble other furniture products or office products.
