The limiting shaft 120 moves relative to the positioning surface 222, the height of the positioning surface 222 is kept unchanged, the door body does not lift relative to the cabinet body 400, and the resistance between the positioning surface 222 and the limiting shaft 120 is beneficial to the suspension of the door body relative to the cabinet body 400.

The opening state comprises a first opening state and a second opening state, and the limiting shaft 120 abuts against the first guide surface 221 from the closing state to the first opening state; from the first open state to the second open state, the stopper shaft 120 abuts against the positioning surface 222.

From the closed state to the second open state, the limiting shaft 120 is firstly contacted with the first guide surface 221, and in the process of moving along the first guide surface 221, the second hinge body 200 rises relative to the closed state, that is, the door body rises and opens relative to the cabinet body 400; the limiting shaft 120 moves to a position where the limiting shaft is separated from the first guide surface 221 and abuts against the positioning surface 222, the height of the second hinge body 200 is kept unchanged, the limiting shaft 120 and the limiting groove 220 only move relatively in the extending direction of the limiting groove 220, and at the moment, the door body keeps moving horizontally and continues to be opened and does not rise any more. From the second open mode to the closed mode, spacing axle 120 moves along locating surface 222 horizontal motion earlier, moves the first guide surface 221 of butt, and second hinge body 200 descends for the door body descends for cabinet body 400, and the door body leans on self gravity to slide down along first guide surface 221, carries out the helping hand to the closing process of the door body, makes the door body closing process more laborsaving.

The opening angle of the first opening state is smaller than that of the second opening state, and a dividing point of the first opening state and the second opening state can be selected according to needs, for example, the opening angle of the dividing point is 60 degrees or 90 degrees. The second open state includes a maximum open angle.
