The outward movement of the support plate 27 drives the door body 13 to move outward inside the slide slot 12, and the door body 13 can be opened.

[0044] When the door body 13 needs to be closed, the reciprocating motor 22 is started to rotate in the reverse direction.

[0045] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0046] The movable assembly includes a third fixing plate 31, a pulley 32, a shielding plate 33, a slot 34, a fixing hole 35, a handle 36, a fixing column 37 and a telescopic spring 38.

When the shielding plate 33 moves to the outside, a rotational force is applied to the handle 36 again, so that the handle 36 and the shielding plate 33 rotate along the pulley 32. At this time, the inner side surface of the shielding plate 33 is rotated to the outer position, and an outward force is applied to the handle 36 again, so that the handle 36 drives the shielding plate 33 to move to the inner position of the third fixing plate 31. At this time, the force applied to the handle 36 is stopped, and the handle 36 and the fixing column 37 move inward under the elastic force of the telescopic spring 38.
