[0056] The side wall corresponding to the straight edge of the fan-shaped groove 922 is provided with four fourth circular placement slots 924. The four fourth circular placement slots 924 are located in pairs on both sides of the side wall, and the four fourth circular placement slots 924 are placed symmetrically in mirror image along the first circular through hole 923. The first guide rod 914 and the second guide rod 915 are both arc-shaped. The two ends of the first guide rod 914 are respectively inserted into the two fourth circular placement slots 924 located in the middle, and the two ends of the second guide rod 915 are respectively inserted into the two fourth circular placement slots 924 located on the outer side.

[0057] The reset plate 913 is located on the right side of the sector groove 922. The reset plate 913 is a sector-shaped block with a central angle of 90°. The reset plate 913 is fixedly connected to the rotating rod 8. The reset plate 913 and the rotating rod 8 are fixed by welding. The top of the reset plate 913 is provided with a first clearance arc groove 925 and a second clearance arc groove 926. The first guide rod 914 is located in the first clearance arc groove 925, and the second guide rod 915 is located in the second clearance arc groove 926. The first spring 916 and the second spring 917 are both located on the left side of the reset plate 913.

[0058] Each clamping block 7 is an arc-shaped block with a rounded corner of 49°. The front and rear sides of each clamping block 7 are rounded. Each clamping block 7 is concentric with its corresponding fire extinguisher 4. The front side of each clamping block 7 is located in front of the center of its corresponding fire extinguisher 4.

Each rotating rod 8 has a second threaded hole 812 at its upper end on its rear side, corresponding to the sixth circular through hole 712. Each sixth circular through hole 712 has a second bolt 713 inside it, and each second bolt 713 is threadedly connected and fixed to its corresponding second threaded hole 812.

[0061] To facilitate the fixing of the base 911 and the cover 912, the bottom of the cover 912 is also provided with an annular placement groove 927. The "convex"-shaped step at the lower end of the base 911 is located in the annular placement groove 927. The inner top wall of the annular placement groove 927 is provided with a number of first threaded holes in a circular array. The bottom circumference of the base 911 is also provided with a number of second circular through holes corresponding to the number of first threaded holes.

Each countersunk bolt 928 is threadedly connected to its corresponding first threaded hole.

[0062] The inner bottom wall of the housing 1, where the fire extinguisher 4 is placed, is generally not in direct contact with the ground and is raised. Therefore, a support plate 111 is fixedly installed at the bottom of the housing 1. The support plate 111 is located below the flat plate and has holes in it to allow the rotating rod 8 to pass through. Each limiting component 6 is fixedly located on the top of the support plate 111. An annular fixing block 929 is fixedly installed at the lower end of the outer wall of each cover 912. Several third circular through holes are arranged in a circumferential array on the top of each fixing block 929. A fourth circular through hole corresponding to several third circular through holes is opened on the top of the support plate 111. A first bolt 930 is installed in each third circular through hole. Each first bolt 930 passes through its corresponding fourth circular through hole. A nut 931 is threaded onto each first bolt 930.

[0063] To facilitate fixing the support plate 111, a bent edge 112 is provided on each of the four sides of the support plate 111. The bent edge 112 abuts against the lower end of the interior of the box body 1. A seventh circular through hole is provided on the four side walls of the box body 1 and the bent edge 112. A third bolt 113 is provided in each seventh circular through hole, and a third nut 114 is threaded onto each third bolt 113.

[0064] Detailed installation process:

[0065] Step 1: Insert the bearing 920 into the first placement groove of the base 911 with an interference fit;

[0066] Step 2: Fit the first spring 916 onto the first guide rod 914 and the second spring 917 onto the second guide rod 915;

[0067] Then, the two ends of the first guide rod 914 are respectively inserted into the two fourth circular placement slots 924 located in the middle of the cover 912, and the two ends of the second guide rod 915 are respectively inserted into the two fourth circular placement slots 924 located on the outer side.

[0068] Step 3: Insert the rotating rod 8 into the first circular through hole 923 of the cover 912, and the limiting block 811 of the rotating rod 8 is located in the third circular placement groove 921;

[0069] At the same time, the first spring 916 and the second spring 917 are actuated to compress the first spring 916 and the second spring 917. The reset plate 913 is inserted into the right side of the fan-shaped groove 922 of the cover 912. The first guide rod 914 is located in the first clearance arc groove 925, and the second guide rod 915 is located in the second clearance arc groove 926.

[0070] Step 4: Insert the base 911 into the cover 912. At this time, the lower end of the rotating rod 8 is inserted into the bearing 920 and the second circular placement groove 919, and the bottom of the limiting block 811 abuts against the top of the bearing 920.

[0071] The base 911 is fixed to the cover 912 by countersunk bolts 928;

[0072] Step 5: Fix the base 911 and cover 912, which were installed in steps 1 to 4, to the top of the support plate 111 using the first bolt 930 and nut 931. After all are fixed, insert the support plate 111 from the bottom of the box 1. At this time, the upper end of each rotating rod 8 is inserted through the through hole of the flat plate. Fix the support plate 111 using the third bolt 113 and the third nut 114.

[0073] Step 6: Fit each clamp 7 onto the upper end of its corresponding rotating rod 8 through the fifth circular through hole 711, and fix it with the second bolt 713.

[0074] Specific implementation process:

[0075] Step 1: When placing the fire extinguisher 4, push the fire extinguisher 4 in. At this time, the fire extinguisher 4 abuts against the rounded corner of the front side of the clamping block 7. Continue to push. At this time, due to the angle and length settings of the clamping block 7, the clamping blocks 7 on both sides of the fire extinguisher 4 rotate to the sides respectively.

[0076] Step Two: With the distance to the left, clamping block 7 is pushed to rotate to the left. At this time, rotating rod 8 rotates, and rotating rod 8 drives reset plate 913 to rotate clockwise in sector groove 922. At this time, first spring 916 and second spring 917 are compressed. When fire extinguisher 4 is pushed to the rear side and concentric with clamping block 7, the transverse central axis of fire extinguisher 4 is located behind the front side of clamping block 7. At this time, no force is applied to the front side of clamping block 7. At this time, first spring 916 and second spring 917 rebound, and first spring 916 and second spring 917 push reset plate 913 to rotate counterclockwise. Reset plate 913 drives rotating rod 8 to rotate counterclockwise. Rotating rod 8 drives clamping block 7 to reset. That is, fire extinguisher 4 is located between two clamping blocks 7. The two clamping blocks 7 limit the fire extinguisher 4 but do not clamp it tightly, which makes it easy for operators to quickly take it out. At the same time, it avoids the fire extinguisher 4 from tipping over when a passerby accidentally touches it.

[0077] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
