When the rack 204 moves and drives the gear column 205 to rotate in one direction, each rotation of the gear column 205 in each direction will cause the barrel 103 to rotate 180 degrees, 180 degrees to the left and 180 degrees to the right, and then the barrel 103 can rotate 360 ​​degrees, so that the spray direction of the barrel 103 is expanded from a fixed-size sector to a 360-degree circle.

[0027] The side of the first gear plate 201 is fixedly connected to the driving rod, the other end of the driving rod is rotatably connected to the box body 101 and fixedly connected to the first motor 208, the first motor 208 is fixedly connected to the box body 101, and the middle part of the gear column 205 is fixedly connected to the transmission rod 206; the first motor 208 is installed outside the box body 101, and drives the first gear plate 201 to rotate through the driving rod.

[0033] When the muzzle height of the gun barrel 103 needs to be adjusted, the second motor 302 is started to move the threaded sleeve 306 along the threaded rod 303, so that the slide tube 307 is driven to rise and fall through the support rod 308, thereby adjusting the height of the muzzle of the gun barrel 103, and as the height of the support rod 308 changes, the slide block 309 will slide inside the slide rail 310, and finally the gun barrel 103 can be adjusted to meet different angles, achieving the effect of automatic adjustment without manual operation;

[0034] The two vertical rods 304 can increase the stability of the threaded sleeve 306 when it is raised or lowered.
