[0058] With reference to Figure 11 The outer surface of the first gear 31 is fixedly connected with a containing block 35, and the containing block 35 is located at the side of the grounding sheet 261 close to the containing bullet 27. When the fastening bolt 25 is loosened, the staff member pulls the box door 2, at which time the grounding sheet 261 can move away from the side of the box door 2, so that the grounding sheet 261 can drive the containing block 35 to rotate.

[0059] With reference to Figure 11 The surface of the second gear 32 is meshingly connected with a reminding block 36, and the surface of the box door 2 is provided with a reminding hole 13 through which the reminding block 36 passes. When the containing block 35 drives the first gear 31 to rotate, the first gear 31 drives the second gear 32 to rotate through the gear rod 33, so that the second gear 32 drives the reminding block 36 to extend out of the reminding hole 13, so that the staff member can directly observe the protrusion of the reminding block 36 and know that the fastening bolt 25 is loosened.

[0060] With reference to Figure 11 and Figure 12 The outer surface of the reminding block 36 is fixedly connected with two limiting bullets 361, and the two limiting bullets 361 are curved away from the limiting block. When the reminding block 36 extends out of the reminding hole 13, the limiting bullet 361 resets, at which time the limiting bullet 361 abuts against the outer surface of the box door 2, so that the limiting bullet 361 limits the reminding block 36 from retreating into the reminding hole 13.

[0061] With reference to Figure 11 and Figure 12 The outer surface of the box door 2 is slidingly connected with a stop plate 37, and the moving path of the stop plate 37 intersects with the rotating path of the cover plate 12. The surface of the box door 2 close to the stop plate 37 is provided with a stop inclined surface 371, the distance between the stop inclined surface 371 and the box door 2 gradually decreases along the direction from the reminding hole 13 to the containing groove 21, and the stop inclined surface 371 is located on the moving path of the reminding block 36.

[0062] With reference to Figure 12 The outer surface of the box door 2 is fixedly connected with an elastic block 372, and the elastic block 372 is located on the moving path of the stop plate 37. When the surface of the box door 2 close to the stop plate 37 abuts against the elastic block 372, the stop plate 37 is not limited to move.

[0063] With reference to Figure 12When the reminding block 36 extends from the reminding hole 13, the reminding block 36 drives the stop plate 37 to move, and the limiting spring 361 can be deformed to continuously drive the stop plate 37 to move, so that the stop plate 37 can be located on the rotating path of the cover plate 12, at this time, the stop plate 37 limits the cover plate 12 to be opened, then the limiting spring 361 is located between the elastic block 372 and the stop inclined surface 371, so that the limiting spring 361 can limit the stop plate 37 to reset, and the elastic block 372 limits the limiting spring 361 to move into the reminding hole 13.

[0064] The implementation principle of the embodiment 2 is that when the fastening bolt 25 is loose, the grounding sheet 261 moves away from the cabinet door 2, the grounding sheet 261 drives the containing strip to move, so that the first wheel 31 drives the second gear 32 to rotate through the gear rod 33, then the second gear 32 drives the reminding block 36 to extend from the reminding hole 13, and the reminding block 36 drives the stop plate 37 to move through the stop inclined surface 371, so that the stop plate 37 limits the cover plate 12 to be opened.
