[0034] Through the above structure, the impact force during the percussion of the primer can be reduced, specifically, the primer and the gunpowder have different effects, the effect of the gunpowder is to provide strong propelling force, and the effect of the primer is to ignite the gunpowder, so the impact force generated during the percussion is far lower than the impact force generated by the explosion of the gunpowder, but through the setting of the refrigerator 7, low temperature is generated in the inside of the protective shell 6, in the low temperature environment, the reaction rate of the chemical substances in the primer can be reduced, the heat and gas generated by the primer can be reduced, so that the impact force and the transmission efficiency are affected, and the stability during the percussion of the primer is improved.

[0036] The fixing device 2 further comprises a rotating motor 20 fixedly connected to the top of the collecting box 5, the output end of the rotating motor 20 is fixedly connected to the bottom of the disc 21, a plurality of fixed rings 22 are fixedly connected to the inside of the fixing device 2, the plurality of fixed rings 22 are arranged in a circle, a first air bag 23 is fixedly connected to the inside of each of the plurality of fixed rings 22, a return tension spring 24 is fixedly connected to the inside of each of the plurality of fixed rings 22, one end of the return tension spring 24 is fixedly connected to one side of the abutting block 25 close to the return tension spring 24, a plurality of second air bags 32 are fixedly connected to the bottom of the disc 21, the plurality of second air bags 32 are arranged in a circle, and the plurality of second air bags 32 are respectively connected to the first air bag 23 close to the second air bag 32.

[0037] Through the above structure, cartridges of different sizes can be clamped and fixed, specifically, air is supplied to the inside of the first air bag 23, the first air bag 23 expands to drive the four abutting blocks 25 to move close to each other, and the cartridge is clamped and fixed, when it is necessary to disassemble the cartridge, the air in the first air bag 23 is discharged, the return tension spring 24 is retracted to drive the abutting block 25 to retract, so that the abutting block 25 is separated from the cartridge, and at this time, the cartridge can fall into the collecting box 5 through the collecting groove 19 to be collected.

[0038] A plurality of damping blocks 28 are fixedly connected to the bottom of the disc 21, the plurality of damping blocks 28 are arranged in a circle, a damping rod 29 is dampingly rotatably connected to the inside of each of the plurality of damping blocks 28, a release plate 30 is fixedly connected to one end of the damping rod 29, an extrusion plate 31 is fixedly connected to the other end of the damping rod 29, and the top of the extrusion plate 31 abuts against the bottom of the second air bag 32 close to the extrusion plate 31.

[0039] The top of the collecting box 5 is fixedly connected with an electric rack 35, the top of the electric rack 35 abuts against the top of the extrusion plate 31, the top of the collecting box 5 is fixedly connected with a spring rack 33, the top of the spring rack 33 abuts against the top of the extrusion plate 31, the top of the collecting box 5 is fixedly connected with a release rack 34, and the top of the release rack 34 abuts against the top of the release plate 30.

[0040] More specifically, when it is necessary to fire and recover the primer of the cartridge, the height of the electric rack 35 is adjusted at this time, so that the disc 21 is rotated by the rotating motor 20, in the process of rotation, the top of the electric rack 35 is in contact with the bottom of the extrusion plate 31, and the extrusion plate 31 drives the second air bag 32 to be extruded, so that the gap between the four abutting blocks 25 is controlled, so that the cartridge can be placed on the opposite side of the four abutting blocks 25, and the top of the clamping block 27 abuts against the bottom of the cartridge, to achieve the preliminary fixation of the cartridge. After preliminary fixation, the disc 21 continues to rotate, so that the top of the spring rack 33 abuts against the bottom of the extrusion plate 31, and the extrusion plate 31 drives the second air bag 32 to be further extruded, so that the cartridge is clamped in the four abutting blocks 25. When the cartridge is clamped in the four abutting blocks 25, the extrusion plate 31 cannot continue to extrude the second air bag 32, at this time the top of the spring rack 33 rotates to avoid the extrusion plate 31 on it. Since the damping rod 29 is damped and rotationally connected in the damping block 28, the extrusion plate 31 can still maintain the state of the second air bag 32 after being separated from the spring rack 33. Then the primer of the cartridge is fired, and the gunpowder ash is collected in the collecting box 5 through the ash collecting groove 18. After firing is completed, the disc 21 continues to rotate, at this time the top of the release rack 34 is in contact with the bottom of the release plate 30, and the release plate 30 is driven to rotate, the release plate 30 drives the extrusion plate 31 to rotate, so that the second air bag 32 is not extruded, causing the four abutting blocks 25 to retract. At this time, the cartridge clamped by the abutting block 25 falls into the collecting box 5 through the shell collecting groove 19 for collection. The cartridge can be recovered week after week.

[0041] The firing device 3 is used for firing the primer, and the firing device 3 comprises a firing rack 8 fixedly connected to the top of the collecting box 5, one side of the firing rack 8 is slidably connected with a moving plate 10, and the bottom of the moving plate 10 is fixedly connected with a firing head 4.

[0042] The firing device 3 further comprises a telescopic air cylinder 9 fixedly installed at the top of the firing rack 8, the extended end of the telescopic air cylinder 9 is fixedly connected with the top of the moving plate 10, and the firing head 4 comprises an installation shell 11 fixedly connected to the bottom of the moving plate 10.

[0043] The inner wall top of the mounting shell 11 is fixedly connected with a second compression spring 14, the bottom of the second compression spring 14 is fixedly connected with a second compression shell 15, the second compression shell 15 is slidingly connected in the interior of the first compression shell 13, the inner wall top of the mounting shell 11 is fixedly connected with a third compression spring 16, the bottom of the third compression spring 16 is fixedly connected with a third compression shell 17, the third compression shell 17 is slidingly connected in the interior of the second compression shell 15;

[0044] The compression resistance of the first compression spring 12 is greater than that of the second compression spring 14, and the compression resistance of the second compression spring 14 is greater than that of the third compression spring 16.

[0045] Through the above structure, different sizes of the primer can be fired. Specifically, when the primer needs to be fired, the telescopic cylinder 9 is started at this time, the output end of the telescopic cylinder 9 extends downward, and drives the moving plate 10 to move downward in the interior of the firing frame 8. The downward movement of the moving plate 10 drives the firing device 3 to move downward, so that the primer is fired by the third compression shell 17, the second compression shell 15, the first compression shell 13 or the mounting shell 11. It is worth mentioning that since the compression resistance of the first compression spring 12 is greater than that of the second compression spring 14, and the compression resistance of the second compression spring 14 is greater than that of the third compression spring 16, the size of the pressure area is proportional to the pressure strength, which is convenient for the firing of the primer.

[0046] Working principle: when the primer of the cartridge needs to be fired and recovered, the height of the electric frame 35 is adjusted at this time, so that the disc 21 rotates by the rotating motor 20. In the process of rotating, the top of the electric frame 35 contacts the bottom of the extrusion plate 31, and drives the extrusion plate 31 to extrude the second air bag 32, so that the gap between the four resistance blocks 25 is controlled, so that the cartridge can be placed on the opposite side of the four resistance blocks 25, and the top of the clamping block 27 is in abutment with the bottom of the cartridge, realizing the preliminary fixation of the cartridge;

[0047] After preliminary fixation, the disc 21 continues to rotate, so that the top of the spring frame 33 is in abutment with the bottom of the extrusion plate 31, and drives the extrusion plate 31 to further extrude the second air bag 32, so that the cartridge is clamped in the interior of the four resistance blocks 25. When the cartridge is clamped in the interior of the four resistance blocks 25, the extrusion plate 31 cannot continue to extrude the second air bag 32, at this time the top of the spring frame 33 rotates to avoid the extrusion plate 31 above it. Since the damping rod 29 is dampingly rotatably connected in the damping block 28, the extrusion plate 31 can still maintain the state of the second air bag 32 after being separated from the spring frame 33, and then the primer of the cartridge is fired;

[0048] When the primer needs to be fired, the telescopic cylinder 9 is started at this time, the output end of the telescopic cylinder 9 extends downward, and the moving plate 10 moves downward in the inside of the firing frame 8, the moving plate 10 moves downward to drive the firing device 3 to move downward, so that the primer is fired by the third pressing shell 17, the second pressing shell 15, the first pressing shell 13 or the mounting shell 11, and the firing powder ash enters the inside of the collecting box 5 through the ash collecting groove 18 to be collected;

[0049] After the firing is completed, the disc 21 continues to rotate, at this time, the top of the release frame 34 is in contact with the bottom of the release plate 30, and the release plate 30 is driven to rotate, the release plate 30 rotates to drive the extrusion plate 31 to rotate, so that the second air bag 32 is not pressed, and the four resistance blocks 25 are retracted, at this time, the cartridge clamped by the resistance block 25 falls into the inside of the collecting box 5 through the shell collecting groove 19 to be collected, and the cartridge can be recycled week after week.
