[0025] See also Figures 1 to 4 A multi-launching head of a pneumatic throwing device comprises a launching tube 1, and a launching head rotating disk assembly 2 is installed on one side of the launching tube 1;

[0026] The transmitting head rotating disk assembly 2 includes a connecting member 201, and a rotating disk 204 is rotatably arranged inside the connecting member 201, three sets of fixing bolts 205 are installed on the front end surface of the rotating disk 204, and the fixing bolts 205 are threadedly connected to the transmitting tube 1, sliding blocks 209 are arranged around the rotating disk 204, and a telescopic spring 208 is installed between the sliding block 209 and the rotating disk 204, a guide sleeve 207 is penetrated inside the telescopic spring 208, and a guide rod 206 is penetrated inside the guide sleeve 207, and a guide slot 203 is provided at the connection between the sliding block 209 and the connecting member 201;

[0027] The rotating disk 204 is rotated in the connecting member 201 through the sliding block 209 and the guide slot 203. A positioning magnet 210 is installed inside the guide slot 203, and the positioning magnet 210 is magnetically connected to the sliding block 209. The sliding block 209 is elastically connected to the rotating disk 204 through the guide rod 206, the guide sleeve 207 and the telescopic spring 208.

[0028] By adopting the above technical solution, when the rotating disk 204 rotates, it can simultaneously drive the sliding block 209 to slide in the guide groove 203 until the sliding block 209 and the positioning magnet 210 are attracted to each other, and the position of the sliding block 209 is fixed. At this time, the launching tube 1 in the fixing bolt 205 near the position of the sliding block 209 is aligned with the air outlet cavity of the pneumatic thrower. After the first launch head is launched from the launching tube 1, the rotating disk 204 continues to rotate. At this time, the sliding block 209 and the positioning magnet 210 are separated from each other. As the rotating disk 204 continues to rotate, the second group of sliding blocks 209 and the positioning magnet 210 are attracted to each other, so that the second launching tube 1 is aligned with the air outlet cavity of the pneumatic thrower, and the second launching head is launched from the launching tube 1, thereby realizing quick connection, convenient operation, and quick rescue, effectively solving the problem of low efficiency of traditional shell loading, and greatly improving the rescue efficiency.

[0029] Specifically, Figure 1 and Figure 2 As shown, preferably, a gun body gas cylinder 6 is threadedly connected to one side of the launch head rotating disk assembly 2, and a connecting port 202 is provided at the connection between the gun body gas cylinder 6 and the launch head rotating disk assembly 2, the connecting port 202 is adapted to the position of one group of fixing bolts 205, and the three groups of fixing bolts 205 are evenly distributed along the center of the connecting piece 201 at equal distances, the gun body gas cylinder 6 is communicated with the launch tube 1 through the connecting port 202 and the fixing bolts 205, a gun handle 4 is arranged below the gun body gas cylinder 6, and a trigger 3 is installed at the front end of the gun handle 4, and a buttstock 5 is movably installed on one side of the gun body gas cylinder 6.

[0030] By adopting the above technical scheme, the gun body cylinder 6 adopts the existing thrower assembly, and a compressed air storage area is provided in the gun body cylinder 6 of the thrower. The gun body cylinder 6 includes a cylinder and a piston assembly located in the cylinder, one end of the cylinder is an open end, and a sealing ring is abutted against the open end in the cylinder, and a center box is fixed in the compressed air storage area. A center cavity is formed inside the center box, and an air outlet pipe connecting the center cavity and the outside atmosphere is pierced on the center box.

Since this part of the content is an existing public technical scheme and is not within the scope of improvement of the present technical scheme, it will not be described here. When the pneumatic thrower is used, only the launching tube 1 and the gun body cylinder 6 are kept aligned to launch, and the gun handle 4 is held by hand, and the buttstock 5 is pressed against the chest of the launcher, and the trigger 3 is pulled to launch. When the first shell is launched, the pneumatic thrower is re-inflated.

[0031] Working principle: When the pneumatic thrower is in use, the launch can only be carried out by keeping the launch tube 1 and the gun body gas cylinder 6 aligned. Hold the gun handle 4, and at the same time, the buttstock 5 is against the chest of the launcher, and the trigger 3 is pulled to launch. When the first shell is fired, the pneumatic thrower is re-inflated, the rotating disk 204 is rotated, and the sliding block 209 and the positioning magnet 210 are separated from each other. As the rotating disk 204 continues to rotate, the second group of sliding blocks 209 and the positioning magnet 210 are attracted to each other, so that the second launch tube 1 and the air outlet cavity of the pneumatic thrower are aligned with each other, and the second launch head is launched from the launch tube 1. In this way, the launch of the third launch head is realized, which effectively solves the problem of low efficiency of traditional shell loading and greatly improves the rescue efficiency.
