Further, the fixing structure comprises a positioning hole 23 and a threaded hole 12, and the positioning hole 23 and the threaded hole 12 are respectively arranged on the limiting block 11 and the engagement groove 22; when the positioning hole 23 penetrates through the groove wall of the engagement groove 22, the threaded hole 12 is formed in the limiting block 11; when the positioning hole 23 penetrates through the limiting block 11, the threaded hole 12 is formed in the groove wall of the engagement groove 22; the positioning hole 23 and the threaded hole 12 can be fixedly connected through a screw.

The positioning hole 23 and the threaded hole 12 may be formed according to the actual requirement of the frame assembly, and the fixing structure may be disposed on the front side of the frame assembly, i.e. between the first groove wall 221 and the first side 111, or may be disposed on the rear side of the frame assembly, or between the second groove wall 222 and the third side 113, or may be disposed on the inner side of the frame assembly, i.e. between the groove bottom of the engagement groove 22 and the second side 112. In this embodiment, the engaging groove 22 is formed with the glass bracket 20, the stopper 11 is disposed on the frame body 10, for example, the positioning hole 23 may be formed on the surface of the glass bracket 20 and penetrates into the engaging groove 22, and the threaded hole 12 is formed on the side of the stopper 11 corresponding to the positioning hole 23, which can be understood that the threaded hole 12 may be a blind hole or a through hole, depending on the length of the screw member. The screw member may be a screw, the diameter of the positioning hole 23 is set to be larger than the screw diameter of the screw and smaller than the screw head of the screw, so that when the screw passes through the positioning hole 23 and is in threaded connection with the threaded hole 12, the screw head and the threaded portion of the screw can act on the frame body 10 and the glass bracket 20 respectively, thereby tightly matching the frame body and the glass bracket.

In the scheme of the glass bracket 20, the first supporting portion 21 is connected to the black edge of the glass panel 31, and in the using process of the interactive flat plate, the black edge can generate a certain relative motion with the glass panel 31 due to the relative motion between the glass bracket 20 and the frame body 10, so that the problem can be solved to a certain extent by improving the matching strength of the frame body 10 and the glass bracket 20. In addition, the uneven surface of the first supporting portion 21, or the protrusion of foreign particles, the excessive hardness, and the like may also cause the glass panel 31 to be scratched, resulting in the problem of black edge falling.
