[0024] The effect achieved by the entire embodiment 1 is that when the spray gun is used and the corresponding nozzle 2 needs to be replaced according to the size of the catalyst channel on site, first pull the two handles 10 to one side to separate the corresponding two magnets 13 and the two magnets 7, and keep the four magnets 13 away from the four limiting holes 6, so that the nozzle 2, the two connecting blocks 4 and the two plug blocks 5 can be moved out of the two mounting holes 3. At this time, the required nozzle 2 is placed in the corresponding position, and the two connecting blocks 4 and the two plug blocks 5 installed on one side of the outer wall are inserted into the two mounting holes 3. Since two limiting holes 6 are provided on the top of the two plug blocks 5, magnets 7 are fixedly installed on the bottom of the inner walls of the four limiting holes 6, and then the two handles 10 are loosened. Because the two handles 10 are installed on one side of the four pull rods 9 , four pull rods 9 are movably inserted into the concave seats 8 installed on both sides of the spray gun body 1, and two fixed blocks 12 are installed at the bottom of the four pull rods 9, and two magnets 13 are installed on one side of the two fixed blocks 12, and then two springs 11 are installed between the other side of the two fixed blocks 12 and the bottom of the two concave seats 8, so that through the action of the four springs 11, the four magnets 13 are all inserted into the four limiting holes 6, and because magnets 7 are installed in the four limiting holes 6, and through the action between the four magnets 7 and the four magnets 13, the stability of limiting the two plug blocks 5 at one end of the two connecting blocks 4 in the two mounting holes 3 is improved, and the process of disassembly and replacement is simple, which improves work efficiency, thereby improving the use effect of the spray gun for the catalyst channel.

Since two springs 11 are installed between the two concave seats 8 and the two fixing blocks 12, and four pull rods 9 are installed between the two fixing blocks 12 and the two handles 10, the four springs 11 are in a compressed state at this time, and then the two handles 10 are released, and under the action of the four springs 11, It drives the four pull rods 9 to move inward, and drives the two fixed blocks 12 and the four magnets 13 to be inserted into the four limiting holes 6. Because the bottom of the inner wall of the four limiting holes 6 is installed with a magnet 7, the stability of the two plug-in blocks 5 at one end of the two connecting blocks 4 being respectively limited in the two mounting holes 3 is ensured through the action of the four magnets 13 and the four magnets 7. The process of disassembling and replacing the nozzle 2 is simple, which reduces the time for disassembly and replacement, improves the work efficiency on site, and thus improves the use effect of the blowing gun used for the catalyst channel.
