Thus, the layout structure is ingenious, facilitating assembly and having strong practicability.
[0035] When the door needs to be opened, the driving member 5 drives the first connecting rod 3 or the second connecting rod 4 to rotate. The first mounting plate 1, the second mounting plate 2, the first connecting rod 3, and the second connecting rod 4 form a spatial four-bar linkage mechanism.

One end of the second connecting rod 4 is rotatably connected to the first mounting plate 1 through a third rotating shaft, and the other end of the second connecting rod 4 is rotatably connected to the second mounting plate 2 through a fourth rotating shaft. As Figure 1 and Figure 2 shown, the driving member 5 is fixed on the first mounting plate 1, the first mounting plate 1 is fixed on the door, the driving shaft 51 is fixedly connected to the first rotating shaft, the driving member 5 drives the first rotating shaft to rotate, the first rotating shaft drives the first connecting rod 3 to rotate relative to the first mounting plate 1 and the second mounting plate 2, and at the same time, drives the second connecting rod 4 to rotate relative to the first mounting plate 1 and the second mounting plate 2.

Further, third shaft holes for cooperating with the third rotating shaft and fourth shaft holes for cooperating with the fourth rotating shaft are formed on both the third side plate 42 and the fourth side plate 43. In this way, the rotational connection between the second connecting rod 4 and the first mounting plate 1 and the second mounting plate 2 is realized.
