The rotation of 4 can drive the spray gun 16 fixed between the arc blocks 104 to swing up and down to spray the mountain. When the spray gun 16 has not been installed between the arc blocks 104, the pushing assembly can push the installation rod 103 to retract into the cavity 102, so that the space formed between the arc blocks 104 is larger than the volume between the spray gun 16 and the arc block 104, so that the spray gun 16 can be inserted between the arc blocks 104 for installation. At the same time, different sizes of spray guns 16 can be installed between the arc blocks 104, which has a wider adaptability.

When the mounting rod 103 rotates, it can drive the slider 302 to rotate, and the slider 302 drives the strip block 300 to rotate, and the strip block 300 drives the round rod 101 to rotate, so that the spray gun 16 can rotate with the round rod 101. At the same time, the mounting rod 103 is limited to prevent it from rotating in the cavity 102. It can only be extended and retracted in the cavity 102, so that the arc block 104 is easier to fit and fix with the spray gun 16.

After the spray gun 16 is installed, the cylinder 005 can be started, and the spray gun 16 can be driven to swing back and forth and left and right through the first arc plate 11 and the second arc plate 12. After adjusting the spray gun 16 to aim at the mountain to a suitable angle, the output of the cylinder 005 is stopped, and the gear 001 and the rack 004 limit the first arc plate 11 and the second arc plate 12, so that the connecting rod 14 cannot shake, but can rotate through the limiting hole 13, and then the water pump is started, and the spray gun 16 is controlled to swing up and down through the handle 500. At the same time, the spray gun 16 can be controlled to rotate in a circle to spray the mountain.
