Wherein the ratchet 338 is a four-tooth ratchet. The specific assembly structure and working principle among the barrel 2, the rotating shaft 12 and the ratchet mechanism 333 belong to the prior art, and the worker in the field can refer to the structure and working principle of the existing hand wheel gun, so that the detailed description is omitted here.

Referring to fig. 1, 2, 3 and 5, in particular, the second driving unit 34 includes a second slider 341, a second guide rail 342, a push rod 343, an electromagnet 344 and a click pin 345, the second slider 341 being disposed on the upper end surface of the mounting plate 2 to be movable left and right through the second guide rail 342; a strip-shaped hole 321 is formed in the upper end of the firing pin 32, one end of a push rod 343 is pivoted to the second slider 341, and the other end of the push rod 343 is movably connected to the firing pin 32 through a pin 322 in cooperation with the strip-shaped hole 321; the side wall of the stroke sleeve 31 is provided with a mounting hole 311, one end of the detent 345 is connected to the electromagnet 344, and the other end is movably arranged in the mounting hole 311. Wherein the detent 345 is connected to the electromagnet 344 by a pin 347.

Referring to fig. 1, 2 and 3, the second slider 341 is the first slider 331, and the second rail 342 is the first rail 332. As a preferable scheme: the first guide 332 is a ball linear guide, a screw linear guide, or a cylinder, but the first guide 332 is not limited thereto.

Referring to fig. 5, the striker 32 has an annular protrusion 323 at a lower end thereof, and an end of the click pin 345 has a relief step 346 engaged with the annular protrusion 323. The receding step 346 may clamp the annular protrusion 323 at the mounting hole 311, so as to clamp the firing pin 32, such that the spring sleeved on the firing pin 32 is compressed to store elastic potential energy for the next firing.

Referring to fig. 1, 2 and 3, the present invention further includes an electronic control system (not shown) electrically connected to the first and second drive units 33 and 34.

With reference to fig. 1, 2, 3, 4 and 5, a specific embodiment of the present invention is explained:

the main driving force of the present invention is from the first slider 331, when the first slider 331 moves to the left, the push rod 343 pushes the striker 32 upwards, so that the striker 32 is locked by the detent 345 connected to the electromagnet 344, and at this time, the compressed spring stores elastic potential energy; meanwhile, the connecting rod 334 drives the driving swing rod 336 to swing left and right around the center of the ratchet 338, and according to the characteristics of the ratchet mechanism 333, the driving pawl 335 will drive the ratchet 338 to rotate through a certain angle under the action of the torsion spring along with the left and right swing of the driving swing rod 336. At this time, the shaft 12 is rotated by the ratchet 338, thereby rotating the chamber 1 by the same angle. After the rotation of the barrel 1, another cartridge is provided in the magazine 11, ready for the next firing. The bullet used in the invention is an empty-packed bullet, and the small solid particles with irritation in the gun bore 1 are fired by the shock wave generated by firing to interfere with the suspicious target person to escape.

FIG. 2 is a schematic structural view of a cocked state of the present invention. At this time, the first slider 331 moves rightwards to drive the left end of the push rod 343 to move downwards along the strip-shaped hole 321, the strip-shaped hole 321 has enough length to avoid the relative distance generated by the left-right movement of the connecting rod 334, so as to ensure that the firing pin 32 is in a state of being clamped by the bayonet 345, and the connecting rod 334 drives the driving swing rod 336 to swing leftwards and rightwards, so that the driving pawl 335 rotates by a certain angle and is in a stroke-off state.

FIG. 3 is a schematic structural view of a fired state of the present invention. After the electromagnet 344 is electrified, the bayonet 345 is pulled to move backwards, and the firing pin 32 rapidly hits the bullet in the gun chamber 1 downwards under the action of the elastic potential energy of the spring, so that the firing is realized.

When in use, the invention is arranged on a patrol car with a camera. Firstly, the electronic control system commands the electromagnet 344 to be electrified so as to enable the bayonet 345 to move backwards, then the electronic control system commands the first sliding block 331 on the first guide rail 332 to move leftwards, the push rod 343 pushes the firing pin 32 upwards so as to enable the firing pin 32 to be clamped by the bayonet 345, the compressed spring stores elastic potential energy, and at the moment, the gun is in a state as shown in fig. 1; then, the electronic control system commands the first slide block 331 on the first guide rail 332 to move rightwards, so that the gun is in the state shown in fig. 2, and at the moment, the patrol with the patrol car is started; finally, when the camera of the patrol car catches a suspicious target and judges that the gun needs to be fired, the electric control system converts the image signal into an electric signal to command the electromagnet 344 to lose power, the clamping pin 345 moves backwards to fire the bullet, and the gun is in the state shown in fig. 3. After the gun shooting is finished, the electric control system repeats the first three combined instructions.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
