When the display completely enters the main body frame 1, the bottom presses down the bending part 311 positioned at the lowest part of the transmission member 31, and drives the bevel rotating member 33 to rotate anticlockwise through the transmission member 31 and the connecting member 32 in sequence. As shown in fig. 2, the steel wire 342 pulls the spring 341 to stretch during rotation and drives the rolling bearing 200 up against the cover plate 2 until the rolling bearing is completely covered. The cover plate 2 is in a completely covered state and is correspondingly lowered to the lowest point of the display 3, so that dust or other foreign matters can be prevented from entering the main frame 1, and the normal working table surface is restored.
(2) The rising process comprises the following steps:
as shown in fig. 3 to 4, when the display is lifted up from the fully lowered state by the lifting device, since the spring 341 is in a stretched state, the steel wire 342 drives the bevel rotator 33 to rotate clockwise to drive the rolling bearing 200 to move down, and sequentially drives the bending part 311 to lift up through the connector 32 and the transmission member 31.
As shown in fig. 4, when the bevel rotor 33 rotates to abut against the two stoppers, the corresponding cover plate 2 is fully opened. The cover plate 2 is in the fully opened state corresponding to the display beginning or about to extend out of the main body frame 1, and the continuous rising of the display is not affected.
