The bullet 14 is fixed in the hole 25, and the remaining approximately half is fixed in the fixing hole 21 of the main body 68 of the bullet 14 to fix the bullet 14 to the rear end of the bullet hole 17. It is loaded and fixed in a stable state.

At this time, the spring 15 is compressed between the flange portion 20 of the main body portion 68 of the bullet 14 and the projecting edge 23 of the bullet hole 17, whereby the kinetic energy for pushing the bullet 14 is elastic to the spring 15. It is stored as energy. Then, when the end block member 26 is pushed out by the impact, the elastic force of the spring 15 moves the bullet 14 forward, and the steel ball 24 separates from the fixing holes 21 and 25, so that the bullet 14 is smoothly moved. To fire outward along the bullet hole 17.

As shown in FIGS. 1, 2, and 5, there is one radially provided hole 31 in the fitting rotary shaft 18, and a spring 28 and one steel ball 29 are provided in the hole 31. It is provided. More than half of the steel balls 29 are located in the hole 31, and the remaining part is exposed to the outside of the hole 31 and projects to the outer edge of the fitting rotary shaft 18.

On the other hand, the fitting hole 16 of the cartridge 12 is provided with five fixing holes 38 on the outer periphery thereof. One axial hole 35 is provided on the front end side of the fitting rotary shaft 18, and a laser sighting device 36 is installed in the hole 35. The laser sighting device 36 is a laser beam. The bundle 37 can be ejected to aim at the target.

The laser sighting device 36 has a dry battery (not shown) and is used as a power source for emitting the laser beam bundle 37. A handle 70 is provided on the gun body 11, and a trigger 41 is provided on the front side of the handle 70. The trigger 41 is attached to the gun body 11 with a pivot pin 42, and a trigger portion 43 at the end thereof is configured to push and move the impact member 44.

A spring 46 is attached to the pivot pin 42 so as to return the trigger 41 to its original position. The impact member 44 is pivotally attached to the gun body 11 by a pivot pin 45, and the spring 47 attached to the pin 45 causes the impact member 44 to return to its original position. Further, a drive member 48 is interlocked with the trigger 41, and the drive member 48 intermittently rotates the cartridge 12 by a predetermined angle via the drive key 33 and the key groove 34.

This rotation angle is 360 ° / 5 = 72 ° when there are five bullet holes 17, and 360 ° / 6 = 60 ° when there are six bullet holes 17. Become. The spring 51 pivotally attached to the fixed column 50 acts on the drive member 48 to maintain the contact between the drive member 48 and the gear 30. The gear component 52 is pivotally mounted on the impact member 44 with a pivot pin 52.

One end of the spiral spring 54 acts on the gear part 52, and the other end acts on the impact member 44 so that the trigger part 43 of the trigger 41 can push and move the gear part 52. Then, after the striking ends, the triggering part 43 slides the gear component 52 and returns to the position before the impact. When operating the shooting gun, the user grasps the handle 70 of the gun body 11 with the right hand, holds the cartridge 12 with the left hand, and inserts the rotary shaft 18 into the fitting hole 16 of the cartridge 12. Then, the cartridge 12 is pushed in sufficiently, and the fixing hole 38 of the cylinder 13 and the steel ball 29 of the fitting rotary shaft 18 are fitted to each other. You are now ready to fire and you can start firing.

At the time of shooting, the laser beam bundle 37 emitted from the laser sighting device 36 can be used to shoot by simply projecting the beam bundle 37 on a target object. Further, if the rear aiming section 55 on the gun body 11 and the aiming section 19 of the cylinder 13 are used to match them with the target object, it is still possible to aim and shoot. When the shooter pulls the trigger 41, the trigger portion 43 of the trigger 41 pushes and moves the gear part 52 of the impact member 44, which causes the impact member 44 to rotate counterclockwise about the pivot pin 45. Rotate in the direction to compress the spring 47. When the trigger portion 43 is further pulled and the trigger portion 43 slides the gear component 52, the impact member 44 is momentarily released, and at this time, the energy stored in the spring 47 causes the impact member 44 to move. Rotates in a clockwise direction, and the impact portion 56 of the impact member 44 impacts the end closing member 26 at the rear end of the bullet 14 with a large instantaneous force.

The end block member 26 that receives such an impact force once receives an impact and moves forward. Due to this movement, the steel ball 24 falls toward the inside, and even if it does not fall inside, the steel ball 24 is pushed by the spring 15 because it is receiving the elastic force of the spring 15. As a result, the locked state of the bullet 14 is released, and the bullet 14 is fired toward the target object along the bullet hole 17 by the elastic force of the spring 15.

During the process of pulling the trigger 41, the driving member 48 interlocked with the trigger 41 slides and pushes the gear 30 to rotate the fitting rotary shaft 18 at a constant angle, for example, 72 °. The rotation of the fitting rotation shaft 18 is transmitted to the key groove 34 of the cylinder 13 via the drive key 33, whereby the cartridge 12 rotates at the same time as the fitting rotation shaft 18 by the same rotation amount.

As shown in FIGS. 4 and 5, the steel ball 29 of the fitting rotary shaft 18 is set so that the fitting rotary shaft 18 and the cartridge 12 are accurately set at predetermined positions after each rotation. And one of the five fixing holes 38 of the fitting hole 16 are utilized so that the bullet 14 to be fired is always in a predetermined position of the gun body 11.

After all the bullets 14 have been fired, the shooter can remove the used cartridge 12, attach a new cartridge 12 to the rotary shaft 18, and continue shooting. it can. FIG. 6 shows another embodiment of the shooting gun according to the present invention. The bullet 14a shown in this embodiment has a tubular main body 69 and a flange portion 20a provided at the front end of the main body 69, and three bullets (or A large number of fixing holes 21a and one central hole 22a are provided.

The spring 15a is fitted on the outer periphery of the main body 69 of the bullet 14a, the front end of the spring 15a acts on the flange portion 20a, and the rear end thereof is a projecting edge 23a provided on the rear end side of the bullet hole 17a. Is acting on. The locking portion of the bullet 14a is fitted into three (or more than two) steel balls 24a and the center hole 22a of the bullet 14a, and the steel ball 24a is fitted into the bullet hole 17a and the bullet 14a. And an end block member 26a to be held between.

In this embodiment, about half of the steel ball 24a is fitted into the fixing hole 25a provided in the projecting edge 23a of the bullet hole 17a, and the other half is the main body of the bullet 14a. It is fitted into the fixing hole 21a of the portion 69. At the same time, one end closing member 26a is fitted into the center hole 22a of the main body 69 of the bullet 14a, whereby approximately half of the steel ball 24a is fixed to the projecting edge 23a of the bullet hole 17a. The bullet 14a is fixed in a state of being fitted in the hole 25a, and the remaining approximately half is fixed in a state of being fitted in the fixing hole 21a of the main body 69 of the bullet 14a, so that the bullet 14a is attached to the rear end side of the bullet hole 17a. It is loaded and fixed in a stable state.

At this time, the spring 15a is compressed between the flange portion 20a of the main body 69 of the bullet 14a and the projecting edge 23a of the bullet hole 17a, whereby the movement energy for pushing the bullet 14a is applied to the spring 15a. It is stored as elastic energy. Then, when the end block member 26a is impacted and pushed out, the bullet 14a is moved forward by the elastic force of the spring 15a, and the steel ball 24a separates from the fixing holes 21a, 25a, and the bullet 14a is removed. It is smoothly fired outward along the bullet hole 17a.

The above-mentioned structure is the same as that shown in FIG. 4, but the bullet 14a shown in this embodiment has the salient features described below. That is, one round ring-shaped concave hole 61 is formed at the front end of the main body portion 69 of the bullet 14a, and the projecting column 62 is provided at the center of the concave hole 61.

It is included. Instead of the anesthetic liquid 67, for example, explosives that explode due to impact can be filled in the space. One surface of the piston 64 is in contact with the protrusion 62. A rubber protective cover 65 is covered on the outer circumference of the needle cylinder 63, and the protective cover 65 surrounds the outer circumference of an injection needle tube 66 provided on the front end side of the needle cylinder 63. With this configuration, the anesthetic liquid 67 is sealed and held in the needle cylinder 63.

In the bullet 14a configured as described above, when the bullet 14a hits the target object, the injection needle tube 66 first pierces the rubber protective cover 65, and the tip thereof is pierced into the target object. On the other hand, when the bullet 14a hits the target object, a large reaction force is generated with respect to the protective cover 65 and the needle barrel 63, and the reaction force relatively shortens the distance between the needle barrel 63 and the bullet 14a. Then, the anesthetic solution 67 in the needle cylinder 63 is compressed and injected from the injection needle tube 66 into the inside of the target object, and the target object is anesthetized for a short time and loses resistance.

At the same time, the protective cover 65 is pressed rearward by the reaction force, and the state shown by a virtual line 65 'in FIG. 7 is obtained. Then, after the anesthetic solution 67 in the needle cylinder 63 has been injected into the target object from the injection needle tube 66, the protective cover 65 is restored to its original state by the elastic deformation energy accumulated by pressing the protective cover 65. After returning, the injection needle tube 66 comes out of the inside of the target object, and the bullet 14a and the injection needle tube 66 come off from the target object.

In the cartridge type continuous shooting gun of the present invention, for example, if the bullet 14 is made of plastic, it can be used as a toy gun. Also, as an anesthesia type underwater gun, if carried by a diver, it will be suitable for protection from sharks. Furthermore, it becomes possible to use it as a gun with relatively weak killing ability for defense of the general public and for police or guardmen.
