Rotating support tube 130 is coupled to the upper portion of the brush body (110). 3 is an exemplary view showing a process of coupling the rotating support tube 130 and the brush body 110.

As illustrated, the rotation support pipe 130 includes a shaft insertion pipe 131 having a predetermined length, and a pair of rotation shaft coupling rings 133 extending under the shaft insertion pipe 131.

The support shaft 150 is coupled to the upper portion of the shaft insertion pipe 131. At this time, the support shaft 150 is detachably coupled to the shaft insertion pipe 131. Accordingly, the user can use the support shaft 150 of a length suitable for the height to be painted by being coupled to the shaft insertion pipe 131.

A square tube 132 is formed on the upper inner wall surface of the shaft insertion tube 131. In the square tube 132, a fitting rod 151 of the support shaft 150 having a cross section is inserted.

The pair of rotation shaft coupling rings 133 are disposed on the same axis as the rotation shaft coupling ring 113 to support the rotation shaft 140 to be inserted. The pair of pivot shaft coupling rings 133 are disposed before and after each of the pivot shaft coupling rings 113. Accordingly, the rotation shaft coupling ring 113 can be rotated left and right between the pair of rotation shaft coupling rings 133.

The outer diameter of the rear coupling shaft 143 is formed to correspond to the diameter of the pivot shaft coupling ring 113 is to allow the angle of the brush body 110 to be adjusted only when the user forcibly applies a force. This is because when the outer diameter of the rear coupling shaft 143 is smaller than the diameter of the rotation shaft coupling ring 113, the angle of the brush body 110 can be adjusted even if the user does not want it.

The user positions the pair of fitting protrusions 141b to fit the pair of protrusion guide grooves 143c, and then presses the front insertion shaft 141 into the rear coupling shaft 143. When the front insertion shaft 141 is pressed into the rear coupling shaft 143, the fitting projection 141b is fitted into the protrusion insertion hole 143b to fix the position.

Meanwhile, a rear support plate 143a is provided at the rear of the rear coupling shaft 143 to limit the depth at which the rear coupling shaft 143 is inserted into the rotation shaft coupling ring 133.

The support shaft 150 is coupled to the shaft insertion pipe 131 of the rotation support pipe 130. Support shaft 150 is formed to have a variety of lengths can be used by replacing the support shaft 150 of a length corresponding to the height to be painted.

The support shaft 150 is formed with a fitting rod 151 at a lower length. The user can forcibly fit the fitting rod 151 to the square tube 132 to easily detach the support shaft 150 from the pivot support tube 130.

The handle 160 is provided on the upper end of the support shaft 150 so that the user can grip it by hand. The handle 160 is formed of a material that can be prevented from slipping, such as rubber.

The process of using the paint brush 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 5.

As illustrated in FIG. 1, the user prepares the paint brush 100. At this time, the user can be used by combining the support shaft 150 having a length suitable for the height of the place where he or she wants to paint on the rotation support pipe 130.

When the user paints a wide area of the wall surface, the brush head 120 is positioned and used in a direction perpendicular to the brush body 110 as shown in FIG. 1. However, when painting a narrow space or corner where the width of the brush body 110 does not enter, the brush body 110 is rotated around the rotation shaft 140 and used as shown in FIG. 4.

The user adjusts the angle of the brush body 110 by holding the brush body 110 with one hand and pressing the rotation support tube 130 with the other hand.

With the angle adjusted, the user can perform painting using the paint brush 100 in a narrow space.

On the other hand, if the brush head 120 is damaged by a repetitive painting operation, or if you want to paint a different color, the user inserts the brush rail while the angle of the brush body 110 is adjusted as shown in FIG. 5. The rail coupling member 123 is separated from the 111 and a new brush head 120 can be fitted and used.

When separating the brush head 120, the user can use a pressing member (not shown) capable of pressing the rail coupling member 123 fitted to the brush insertion rail 111.

As described above, the paint brush according to the present invention is provided so that the brush body can be angled with respect to the rotation support tube. Accordingly, not only a large area but also a small space such as a corner or a corner can be painted by using a single paint brush without replacing it with a small paint brush.
