Thus, the paint brush assembly has a two-stage anti-reverse effect, so that the paint contained in the container can be supplied into the barrel conveniently and can be supplied into the connecting pipe conveniently. In addition, the paint brush assembly has a two-stage anti-reverse effect, thereby preventing the paint from leaking.
