The length direction of the gun guide rail 200 is arranged along the front and back direction, and the spray gun tube 100 is arranged on the gun guide rail 200. The front and back driving assembly is used to drive the spray gun tube 100 to move along the length direction of the gun guide rail 200. The rotating shaft seat 310 is located below the gun guide rail 200, and the spherical rotating shaft 300 is installed in the rotating shaft seat 310. The spherical rotating shaft 300 is connected to the gun guide rail 200, and the gun guide rail 200 can rotate up, down, left and right around the spherical rotating shaft 300. Among them, the left and right driving assembly is used to drive the gun guide rail 200 to rotate left and right, and the up and down driving assembly is used to drive the gun guide rail 200 to rotate up and down. Specifically, the spherical shaft 300 is located near the middle of the gun guide rail 200. The upper part of the spherical shaft 300 is a short rod, which is fixed to the gun guide rail 200 by screws. The lower sphere of the spherical shaft 300 and the shaft seat 310 are spherical shells, which are adapted to the sphere of the spherical shaft 300. The spherical shaft 300 can rotate freely in the shaft seat 310. The front end of the spray gun tube 100 is provided with a water outlet facing upward, and the gun guide rail 200 is tilted downward.

[0045] The gun guide rail 200 of the present invention is connected to a spherical shaft 300. The multi-directional free rotation characteristics of the spherical shaft 300 and the driving action of the left and right drive components and the up and down drive components are utilized to realize the up, down, left and right rotation of the gun guide rail 200. In addition, the spray gun tube 100 can move forward and backward along the gun guide rail 200, so that the direction of the spray gun can be adjusted in the three directions of the XYZ axis.

Since the second rotating connecting member 600 is eccentrically connected to the first bracket 400, the first bracket 400 rotates up and down with the rotation of the second rotating connecting member 600. Since the first bracket 400 is connected to the gun discharge guide rail 200 through the first rotating connecting member 500, when the first bracket 400 rotates up and down, it will drive the gun discharge guide rail 200 to rotate up and down.
