After installation, the fire extinguisher box body 1 needs to be adjusted. When adjusting the position, it is only necessary to use the first handle 17 to pull the first pull rod 16 upward on the fixed frame 8, and the first pull rod 16 pulls the driving frame 18 to slide upward in the driving groove 21 of the driving plate 20. The driving frame 18 squeezes the groove wall of the driving groove 21, pushing the driving plate 20 to drive the positioning rod 22 to move toward the side away from the mounting plate 5, thereby pulling one end of the positioning rod 22 out of the positioning groove 23 on the mounting plate 5, releasing the positioning of the fire extinguisher box body 1 on the mounting plate 5, and then using the sliding of the adjustment seat 9 on the cross bar 10 and the sliding of the adjustment seat 9 on the vertical rod 13, the fire extinguisher box body 1 can be adjusted horizontally and vertically on the mounting plate 5. In the vertical direction, the position of the fire extinguisher box body 1 is flexibly adjusted. After the adjustment, the first handle 17 is released. Under the pulling force of the first spring 19, the driving frame 18 is pulled to slide downward in the driving groove 21 to reset, so that one end of the positioning rod 22 is inserted into the positioning groove 23 at the corresponding position on the mounting plate 5. The fire extinguisher box body 1 after the position adjustment can be repositioned. When taking the fire extinguisher stored in the fire extinguisher box body 1, the third handle 35 is used to rotate the card 47 on the flip plate 33, and the opening 48 on the card 47 is rotated to the card frame 49. Then, the third handle 35 is used to directly remove the fire extinguisher from the fire extinguisher box body 1. The two sides of the flip plate 33 are pulled open, and when one of the flip plates 33 is pulled open, the other flip plate 33 is automatically driven to rotate out through the two arcuate bars 36 and the transmission plate 37. At the same time, in the process of rotating out, the flip plate 33 drives one end of the insertion rod 40 to slide in the arcuate groove 43, and the insertion rod 40 drives the second moving block 42 to slide in the guide frame 41 to bring out the placement tube 6 and the fire extinguisher. The upward movement of the transmission plate 37 drives the second driving bar 44 to move upward, and the gear 46 drives the rotating shaft to rotate, and the box cover 2 can be opened synchronously, thereby better exposing the fire extinguisher and taking it out.

[0044] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention.
