[0035] The working principle of the anti-accidental-touch urea filling self-sealing gun provided by the utility model is as follows: in the process of filling urea, the filling gun is usually used for operation. In the process of operating the filling gun, in order to avoid accidental touching of the filling gun and causing continuous output of urea, the two sliding frames 41 at the bottom of the operating frame 3 are slid until they are separated and close to the position of the switch rod 6. At this time, the rotating plates 42 on the upper end surfaces of the two sliding frames will support upward, and then the support frame 44 on the surface of one of the rotating plates 42 is used to support and limit the switch rod 6. At this time, the position of the entire switch rod 6 will be unable to move. In the process of operating and using the support frame 44, the arc-shaped support frame 44 can be used for auxiliary operation, and then the screw 43 at the bottom end of the sliding frame 41 is rotated to allow the screw 43 to squeeze and fix the position of the sliding frame 41 to avoid accidental touching of the switch rod 6 when it is not in use.

[0036] When the filling gun is used for a long time, in order to better fix and limit the grip rod 7 fixed at one end of the filling gun and the filling connecting pipe 2, the rotating rod 52 on both sides of the connecting ring 51 on the surface of the filling connecting pipe 2 is rotated to make the rotating rod 52 close to the connecting ring 53 on the surface of the grip rod 7, and then the block 57 on one side of the positioning ring 54 on the surface of the rotating rod 52 is plugged into the positioning hole 58 opened on the surface of the connecting ring 53. At this time, the position of the entire rotating rod 52 and the connecting ring 53 will be effectively fixed and cannot be moved. Thereafter, the rotating shaft 55 on the surface of the rotating rod 52 is rotated, so that the rotating shaft 55 squeezes and fixes the position of the positioning ring 54. In the process of rotating the rotating shaft 55, the protective ring 56 is used for protection to prevent the rotating shaft 55 from loosening and falling off. At this time, the entire rotating rod 52 and the connecting ring 53 are docked and limited, which effectively protects and limits the entire filling connecting pipe 2 and the grip rod 7.
