In this embodiment, the other end of the connecting member 40 may be further provided with a through hole 403, and here, referring also to fig. 4, the buckle 402 is provided on the opposite inner walls of the through hole 403 along the length direction of the connecting member 40, it is understood that the buckle 402 may be provided only one, specifically, the buckle 402 is provided on any one of the inner walls of the through hole 403, or the buckle 402 may be provided in two, specifically, the buckle 402 is provided on two inner walls of the through hole 403. It should be noted that, in practical applications, the number of the fasteners and the specific positions of the fasteners on the inner wall of the through hole along the length direction of the connecting member are flexibly adjusted by designers, and the invention is not limited in particular.

Of course, in some other embodiments, the other end of the connecting element 40 may not be provided with the through hole 403, but the buckle 402 is directly provided on the upper surface of the other end of the connecting element 40, as long as the provided buckle 402 can be engaged with the through hole of another connecting element, similarly, when the buckle 402 is directly provided on the upper surface of the other end of the connecting element 40, the buckle 402 may be provided as one or two, and the like, and in practical applications, the designer also has flexible adjustment, and the invention is not limited specifically.

It should be noted that, in this embodiment, the upper surface of the connecting member 40 may be further coated with a paint, wherein the friction coefficient of the coated paint is lower than the preset friction coefficient threshold value, so as not to add resistance to the bending and folding of the flexible screen. Specifically, the coating can be made of teflon, and it can be understood that the teflon coating has a low friction coefficient, and the friction coefficient changes during load sliding, and the numerical value ranges from 0.05 to 0.15; the coating may also be Polytetrafluoroethylene (PTFE), it being understood that the PTFE coating also has a very low coefficient of friction, ranging from about 0.05 to about 0.2. It should be noted that only two common paints are listed here, and in practical applications, the designer sets the preset friction coefficient threshold value, so as to select the paint below the preset friction coefficient threshold value.

It should be noted that, in the present embodiment, the connecting member 40 may be formed by stamping, that is, the connecting member 40 in the present embodiment may be in the form of a stamping, and it is understood that the stamping is a forming method for applying an external force to a plate, a strip, a pipe, a section bar, etc. by a press and a die to cause plastic deformation or separation of the plate, the strip, the pipe, the section bar, etc. so as to obtain a workpiece (stamping) with a desired shape and size.

It should be noted that, in practical applications, the preset distance range threshold is flexibly set by a designer according to experiments or experience. It can also be understood that, when the distance h1 of the through hole 501 along the length direction of the connecting member 50 is larger, the distance h2 of the buckle 502 along the length direction of the connecting member 50 is smaller, and the sliding distance of the flexible screen is larger.
