[0033] The fixed block 201 is rectangular. By setting the fixed block 201, the first rotating member 202 is fixed. Through the cooperation of the first rotating member 202 and the second rotating member 203, the door panel 103 can be pushed. By setting the resistance member 204, the device has a certain resistance when opening the door panel 103, thereby improving the stability of the door panel 103. By setting the limiting member 205, the door panel 103 can be limited by the resistance member 204.

[0034] Example 2

[0040] A card slot is provided on the outer side of the second rotating shaft 203a, and the part where the connecting block 203b is fixed to the door panel 103 is rectangular, which increases the surface area where it is fixed to the door panel 103, thereby improving the stability of the connecting block 203b. When the door panel 103 is pulled, the door panel 103 drives the hinge 102 to rotate, and the door panel 103 drives the second support rod 203c to rotate, and the second support rod 203c drives the first support rod 202b to rotate through the first rotating shaft 202a and the second rotating shaft 203a.

[0041] Specifically, the resistance member 204 includes a sleeve plate 204a, and the sleeve plate 204a is fixed to the top of the second support rod 203c.

[0042] Specifically, the resistance member 204 further includes a clamping block 204b and a first spring 204c. The clamping block 204b is movable in the sleeve plate 204a. Two ends of the first spring 204c are respectively fixed to the sleeve plate 204a and the clamping block 204b.

[0043] The sleeve plate 204a is rectangular and is engaged with the slot on the outer side of the second rotating shaft 203a through the block 204b, so that it can generate resistance to the opening and closing of the door panel 103, thereby improving the stability of the door panel 103 being opened and preventing the door panel 103 from being too light and being easily deflected by external force. The door panel 103 drives the hinge 102 to rotate, and the door panel 103 drives the second support rod 203c to rotate. The second support rod 203c rotates on the outer side of the second rotating shaft 203a, and the slot on the outer side of the second rotating shaft 203a squeezes the block 204b. The block 204b moves horizontally due to the squeezing. The first spring 204c is squeezed by the block 204b and deforms, continuously pushing the door panel 103. The reaction force of the first spring 204c pushes the block 204b to move and reset. The block 204b is engaged with the slot on the outer side of the second rotating shaft 203a, thereby increasing the resistance to opening and closing the door panel 103.
