The fixing assembly 20 includes a fixing base 21 and a first guide rail 22, the fixing base 21 is fixed to the rear plate 12, and the first guide rail 22 is fixed to the fixing base 21 and extends from the rear plate 12 in a direction toward the front plate 11. The movable assembly 30 comprises a supporting cylinder 31, a mounting plate 32 and a second guide rail 33, the supporting cylinder 31 is sleeved outside the first guide rail 22 and is mounted on the first guide rail 22 through a first sliding block 34, one end, far away from the fixed seat 21, of the supporting cylinder 31 extends out of the first opening 111 and is connected with the mounting plate 32, the mounting plate 32 is used for mounting a display screen, the second guide rail 33 is mounted on the outer side of the supporting cylinder 31 and is parallel to the first guide rail 22, and the second guide rail 33 is slidably connected with a second sliding block 13 arranged on the edge of the first opening 111.
