The length of the supporting rod 2 is smaller than the inner diameter of the base 1, so that the supporting rod 2 naturally falls due to its own gravity when the movable cover 11 is not opened.

[0028] Furthermore, one end of the support rod 2 is installed on the inner surface of the base 1 through a rotating block 21, and the other end of the support rod 2 is installed on the inner surface of the base 1 through a through hole 22. Two groups of rotating blocks 21 are provided, and the two groups of rotating blocks 21 are fixedly connected on both sides of the support rod 2. The diameter of the through hole 22 is the same as the diameter of the mounting hole 25. Under the connection between the rotating block 21 and the mounting hole 25, the support rod 2 rotates around the rotating block 21, and the rotating block 21 is rotatably connected to the surface of the mounting hole 25.

[0029] Furthermore, two groups of first mounting blocks 23 and second mounting blocks 24 are provided, and the two groups of first mounting blocks 23 and second mounting blocks 24 are provided on both sides of the support rod 2. The diameter of the mounting hole 25 is larger than the diameter of the rotating block 21.

[0035] When the movable cover 11 is installed on the inner surface of the base 1, the plug-in block 34 is pushed into the installation bin 3 by a thin rod passing through the through hole 13, so as to drive the limit plate 33 to slide on the inner surface of the installation bin 3, and the support spring 32 is in a compressed state. When the plug-in block 34 is placed in the installation bin 3, the slot 37 is engaged with the outer surface of the installation bin 3, and the installation plate 35 is placed in front of the installation bin 3. After loosening the hard thin rod, the plug-in block 34 passes through the connecting hole 31 and the plug-in hole 36 in turn under the action of the supporting force exerted by the support spring 32, and the limit plate 33 is abutted against the inner surface of the installation bin 3 to limit the movable cover 11.
