The threaded pipe joint and the paint bucket are connected by a hose. When the hand-held push rod is pulled downward, negative pressure is generated in the piston cylinder to suck the paint. At this time, the one-way valve in the threaded pipe joint opens and the second one-way valve closes. Then the hand-held push rod is pushed upward, the second one-way valve opens and the one-way valve in the threaded pipe joint closes, and the paint in the piston cylinder is pressed into the hollow paint brush cylinder.

[0006] Preferably, the paint brush tube includes a plastic tube with side baffles fixed at both ends, the outer part of the plastic tube is provided with a fiber coating layer, and the plastic tube is provided with penetration holes at intervals. The upper end of the hollow rod is connected to the inside of the plastic tube. After the paint is injected into the plastic tube, it penetrates into the surface of the fiber coating layer through the penetration holes.

[0007] Preferably, the outer end surface of the side baffle is provided with a hexagonal countersunk hole, the second bearing sleeve is provided with a hexagonal boss engaged with the hexagonal countersunk hole, and the first bearing sleeve is provided with a hexagonal boss engaged with the hexagonal countersunk hole, so that the plastic cylinder can rotate smoothly using the bearing.

[0008] Preferably, a support arm is fixedly provided at the upper end of the hollow rod, and a screw hole adjustment sleeve is fixedly provided at the upper end of the support arm. An adjusting screw is provided in the screw hole adjustment sleeve through a thread connection. The second bearing sleeve and the bearing cooperating with the second bearing sleeve are arranged at one end of the adjusting screw.

[0010] Preferably, a through opening is provided at one end of the plastic cylinder that cooperates with the upper end of the hollow rod, and the upper end of the hollow rod is inserted into the opening to facilitate feeding. The hexagonal boss is made of rubber, so that it can also play a sealing role when embedded in the hexagonal countersunk hole.

[0011] The advantages and positive effects of the utility model are: the open end surface of the freely rotatable anti-splash shield is always kept parallel to the vertical wall surface under the action of the counterweight plate, which can effectively prevent splashing during the painting process, and the anti-splash shield will not contact the wall surface to be painted;

[0012] During the painting process, the paint is sucked into the piston cylinder by the cooperation of two hands to drive the push rod, and then pressed into the plastic cylinder, and then penetrated outward through the through hole on the plastic cylinder so that the fiber coating layer can be continuously painted, which can effectively improve the painting efficiency.

[0013] Furthermore, by arranging the second bearing sleeve and the first bearing sleeve that cooperate with the bearing, smooth rotation can be achieved, and the plastic cylinder can be conveniently disassembled by adjusting the adjusting screw. BRIEF DESCRIPTION OF THE DRAWINGS
