The movable pull ring 46 can drive the hard tube 42, thereby achieving the effect of conveniently controlling the hard tube 42.

[0035] The working principle of a urea filling gun provided by the utility model is as follows: when it is necessary to use the filling pipe 2 to clamp and inject urea into the equipment, the injection pipe 7 is first connected to the inlet pipe 6, and the injection pipe 7 needs to be connected to the urea storage barrel, and then the handle 5 is held by hand to drive the gun body 1, and the gun body 1 drives the filling pipe 2 to extend into the equipment, and then the switch handle 8 is pressed to inject urea into the equipment. When it is necessary to quickly connect the inlet pipe 6 and the injection pipe 7, the injection pipe 7 is first moved to drive the connecting ring 306, and the connecting ring 306 is connected. Put it into the inner wall of the threaded tube 301. When one side of the connecting ring 306 is fitted with the inlet pipe 6, the adjusting ring 302 is rotated with the help of the anti-slip groove 313 to make the adjusting ring 302 move along the outer wall of the threaded tube 301. The adjusting ring 302 squeezes the sliding ring 303 to make the sliding ring 303 slide along the outer wall of the threaded tube 301. The sliding ring 303 drives the top block 304, and then the top block 304 presses the fixing block 305 until the fixing block 305 enters the fixing hole 307. The injection tube 7 can be connected with the inlet tube 6 to complete the connection. When the injection tube 7 needs to be removed, the adjusting ring 302 is first rotated in the opposite direction with the help of the anti-slip groove 313 to move the adjusting ring 302 in the direction away from the slip ring 303, and then the slip ring 303 is moved to drive the top block 304 to separate from the fixed block 305. At this time, the spring 310 can push the fixed block 305 to move quickly in the direction away from the fixed hole 307 until the fixed block 305 is separated from the fixed hole 307, and then the injection tube 7 can be removed. In the process of the slip ring 303 sliding along the outer wall of the threaded cylinder 301, the positioning plate 311 fixed on the slip ring 303 will move along the arc surface of the positioning rod 312, thereby achieving the effect of improving the stability of the movement process of the slip ring 303. By setting the adjustment device, the personnel can quickly complete the connection between the inlet tube 6 and the injection tube 7, and make the inlet tube 6 fixed firmly, thereby avoiding the leakage of urea in the process of entering the inlet tube 6, thereby improving the stability of the filling gun.

[0036] When the filling pipe 2 needs to be sealed and covered when it is not in use, the hard pipe 42 is first pulled to drive the bellows 41 so that the bellows 41 extends in a direction away from the gun body 1. When the hard pipe 42 moves to a suitable position, the pull ring 46 is pulled to drive the protective cover 45, and the protective cover 45 drives the rubber plug 44, and the rubber plug 44 is inserted into the annular hole 43, so that the filling pipe 2 can be covered and sealed. When the filling pipe 2 needs to be used to add urea to the equipment, the pull ring 46 is pulled to drive the protective cover 45, and the protective cover 45 drives the rubber plug 44 to separate from the annular hole 43. At this time, the elastic rope 48 can drive the bellows 41 to quickly shrink in a direction close to the gun body 1, so as to achieve the effect of being able to quickly adjust the bellows 41. By setting the auxiliary structure 4, when the filling pipe 2 is not in use, the bellows 41 and the protective cover 45 can be conveniently adjusted to cover and seal the filling pipe 2, thereby preventing dust and other dirt from entering the gun body 1 along the filling pipe 2, thereby improving the practicality of the filling gun.
