Further, the first screen connecting part 100 is provided with, for example, one screen connecting plate 330 and the second connecting part 342, and thus, the first screen connecting part 100 can be connected to one screen. In addition, referring to fig. 6, the second screen connecting part 200 is provided with, for example, a support mounting seat 210, a screen supporting member 220 connected to the support mounting seat 210, and a plurality of screen connecting assemblies 230 connected to the screen supporting member 220, and in particular, the support mounting seat 210 may be provided with a second connecting member 342 and a support mounting groove 211, and the screen supporting member 220 is connected to the support mounting groove 211.

Therefore, the screen supporting stand 300 can be connected to the first screen connecting part 100 through the first connecting part 341 connected to the connecting base 350 to realize that the screen supporting stand 300 can be connected to one screen. In another case, the screen supporting frame 300 replaces the first screen connecting portion 100 with the second screen connecting portion 200, that is, the second screen connecting portion 200 is connected to the connection 350 through the matching connection of the first connection member 341 and the second connection member 342, and at this time, the screen supporting member 300 can connect a plurality of screens through the plurality of screen connecting members 230 on the second screen connecting portion 200. Thus, the screen support 300 can respectively connect one screen or a plurality of screens by switching the first screen connecting part 100 and the second screen connecting part 200.

Referring to fig. 2, the first connector 341 includes, for example: a connection plug board 341-1 and a connection socket 341-4 connected to the connection plug board 341-1, wherein the connection plug board 341-1 is provided with a first connection face 341-2 and a second connection face 341-3, the width of the first connection face 341-2 is smaller than the width of the second connection face 341-3, and the width of the connection socket 341-4 is smaller than the average width of the connection plug board 341-1. For example, the connection plug board 341-1 is a trapezoid plug board, a shorter side of the trapezoid plug board is a first connection surface 341-2, and correspondingly, a longer side of the trapezoid plug board is a second connection surface 341-3, the first connection surface 341-2 is located above the second connection surface 341-3, and the connection socket 341-4 is a square structure, and a width of the square structure is smaller than a width of the first connection surface 341-2.
