In order to facilitate subsequent users to directly observe the feeding and remaining paint in the device, the brushing tube head 1, the elastic paint bottle 6, and the L-shaped support plate 2 are all made of transparent plastic;

[0044] The outer side of the coating tube head 1 is provided with a sealing component 7, the rear end of the sealing component 7 is connected to the bottom surface of an L-shaped support plate 2, and the sealing component 7 includes an elastic curved strip 71, a sealing plug 72 and a limiting block 73.

The top end of the sealing plug 72 and the top end of the limiting block 73 are both connected to the surface of the other end of the elastic curved strip 71, and the limiting block 73 is aligned with the sealing plug 72. After the sealing plug 72 and the discharge hole 5 are in a clamping state, the limiting block 73 is fitted and connected to the surface of the coating tube head 1. When the overall device is idle, the elastic curved strip 71 is used to drive the sealing plug 72 to seal the discharge hole 5, thereby preventing the residual paint from flowing out;

[0045] The rear end surface and the front end surface of the elastic paint bottle 6 are respectively connected with the main support arc plate 8 and the top pressure arc plate 10, and the front end of the top pressure arc plate 10 is provided with a movable component 11 and a movable frame 9, and the movable component 11 is installed between the middle part of the top pressure arc plate 10 and the bottom of the movable frame 9, and a spring 13 is installed between the top front end of the main support arc plate 8 and the top of the movable frame 9, and the front end surface of the movable frame 9 is fixedly connected with a T-shaped rod 12, and one end of the T-shaped rod 12 is clamped on the inner side of the top of the movable frame 9;

Then, the movable frame 9 is squeezed, and pressure is applied to the elastic paint bottle 6 through the movable component 11 and the top pressure arc plate 10 until the maximum compression value of the spring 13 is reached. Since the spring 13 has a maximum compression value, the pressure of each installation is basically the same, thereby realizing the effect of quantitative discharging in disguise. The paint inside the elastic paint bottle 6 is sprayed onto the surface of the brush barrel 4 through the discharge hole 5 inside the brush tube head 1.

[0050] Then, holding the elastic paint bottle 6 and the main supporting arc plate 8, the brush barrel 4 is rotated back and forth to apply paint on the damaged position of the wall to perform the repair operation. When the paint inside the elastic paint bottle 6 is used up, the elastic paint bottle 6 can be twisted and disassembled to separate the elastic paint bottle 6 from the painting tube head 1, and then the paint is added to the elastic paint bottle 6, and then the painting tube head 1 and the elastic paint bottle 6 are reset and installed, and continue to use.
