By providing support blocks, and because the rear end of each support block abuts against the front end of the control circuit board, the support strength of the support plate can be improved. Furthermore, because each support block is provided with a plurality of sockets spaced apart from left to right, and each socket penetrates the support block from front to back, and each pin of the display screen passes through the socket at the corresponding position, it can isolate each adjacent pair of pins to avoid short circuits between pins and to prevent pin bending.

[0010] In one possible implementation, a reinforcing rib is provided between every two adjacent support columns. Both ends of each reinforcing rib are integrally connected to the outer walls of the two adjacent support columns at the corresponding positions, and the front end of each reinforcing rib is integrally connected to the rear side of the support plate. By providing the reinforcing ribs, since both ends of each reinforcing rib are integrally connected to the outer walls of the two adjacent support columns at the corresponding positions, and the front end of each reinforcing rib is integrally connected to the rear side of the support plate, the connection strength between the front end of each support column and the rear side of the support plate can be improved.
