[0027] The replacement mechanism 2 includes a fixed block 201, a mounting groove 202 is provided on the front of the fixed block 201, a connecting groove 203 is provided on the back of the fixed block 201, the fixed block 201 is connected with the front of the gun body 1 through the connecting groove 203, empty grooves 208 are provided on both sides of the inside of the fixed block 201, a movable frame 209 is arranged inside the empty groove 208, a clamping block 210 is fixedly installed on the relatively close side of the movable frame 209, the other side of the clamping block 210 is clamped in the inside of the clamping groove 11, a compression spring 212 is fixedly installed in the inside of the empty groove 208, and the other side of the compression spring 212 is fixedly connected to the movable frame 209.

[0028] Specifically, threaded holes 206 are provided on both sides of the fixing block 201 , and the inner threads of the threaded holes 206 are connected with screw rods 205 , and one side of the screw rod 205 extends to the inner side of the movable frame 209 .

[0029] The screw 205 and the threaded hole 206 cooperate with each other to drive the transmission plate 207 to move. When the nozzle 9 needs to be disassembled and replaced, the screw 205 is rotated to drive the transmission plate 207 to move with the cooperation of the threaded hole 206, and then the transmission plate 207 moves to both sides, and the transmission plate 207 drives the movable frame 209 to move to both sides, so that the movable frame 209 drives the block 210 to move, so that one side of the block 210 is separated from the inside of the slot 11, which makes it convenient to pull the connecting square tube 10 out of the mounting slot 202, so as to achieve the purpose of facilitating the disassembly and replacement of the nozzle 9.

[0030] Specifically, a through slot 211 is formed on a relatively distant side of the movable frame 209 , and one side of the screw rod 205 penetrates the through slot 211 .

[0031] The through groove 211 is used to limit the screw rod 205 to prevent the screw rod 205 from deviating, which would cause the screw rod 205 to drive the movable frame 209 to deviate.

[0032] Specifically, the top and bottom of the inner cavity of the empty slot 208 are provided with limit slots, and the top and bottom of the movable frame 209 are fixedly installed with limit blocks, and the limit blocks are located inside the limit slots.

[0033] The limiting groove and the limiting block cooperate with each other to limit the movable frame 209 , thereby improving the stability of the movable frame 209 when moving in the empty slot 208 , and further improving the accuracy of the clamping block 210 being clamped in the inside of the clamping slot 11 .

[0036] Specifically, the surface of the handle 4 is covered with an anti-slip cover 5 , and the bottom of the handle 4 is fixedly mounted with a baffle 6 .

[0037] The anti-slip sleeve 5 is used to increase the friction force on the surface of the handle 4 , thereby making it easier for the user to hold the handle 4 without slipping, thereby improving the user's control over the gun body 1 .

[0038] When the nozzle 9 needs to be replaced during use, first, the screw rod 205 is rotated. With the cooperation of the threaded hole 206, the threaded hole 206 drives the transmission plate 207 to move. When the transmission plate 207 moves to the inner side of the movable frame 209, the transmission plate 207 drives the movable frame 209 to move to both sides, so that the movable frame 209 drives the block 210 to move, so that one side of the block 210 is separated from the inside of the slot 11. At this time, the connecting square tube 10 is taken out from the inside of the mounting slot 202, and the nozzle 9 is replaced. When replacing and installing the nozzle 9, insert the connecting square tube 10 into the installation groove 202 so that the slot 11 is located on one side of the block 210, and then rotate the screw 205 in the opposite direction. The screw 205 drives the transmission plate 207 to move to the middle of the movable frame 209. The movable frame 209 pops open under the elastic force of the compression spring 212, and then the movable frame 209 drives the block 210 to move, so that one side of the block 210 is re-engaged in the slot 11, and the installation of the nozzle 9 is completed.
