[0028] Embodiment 2

[0029] See attached Figure 6 , Figure 7 , Fig. 9 as well as Fig.10As shown, on the basis of the first embodiment, in order to realize the anti-slip limit after the roller brush body 2 is sleeved on the top rod body of the roller brush holder 1, a baffle 3 is sleeved and fixed on the top rod body of the roller brush holder 1, and the roller brush body 2 is clamped between the baffle 3 and the baffle 4. The baffle 4 is a circular ring plate structure, and a slider 5 is fixed on the inner ring surface of the baffle 4. The slider 5 is slidably connected in the slide groove 6, and the slide groove 6 is opened on the surface of the top rod body of the roller brush holder 1; a pick-up groove 7 is opened at the end of the top rod body of the roller brush holder 1, and two parallel side walls of the pick-up groove 7 are opened There is a through opening 8, a stopper 9 is movably inserted in the through opening 8, a rubber support block 10 is fixed between the two stoppers 9, two ends of the rubber support block 10 are respectively fixed on the top surface of the picking groove 7 and the bottom surface of the picking groove 7, the rubber support block 10 has a "cross" shaped main structure, the thickness of the plate body of the rubber support block 10 connected to the stopper 9 is less than the thickness of the plate body of the rubber support block 10 connected to the through opening 8; one end of the stopper 9 extending out of the picking groove 7 is provided with an inclined surface, the inclined surface faces away from the roller brush body 2, and the other end of the stopper 9 is fixed with a paddle 11, and the paddle 11 has a "concave" shaped plate structure.

[0030] After the roller brush body 2 is sleeved on the top rod body of the roller brush frame 1, one end of the roller brush body 2 is blocked by the baffle 3, and then the baffle 4 is sleeved on the top rod of the roller brush frame 1, pushing the baffle 4 to slide along the top rod body of the roller brush frame 1. In this process, the baffle 4 squeezes the baffle 9 along the inclined surface, and the baffle 9 slides along the through-hole 8 under pressure, and the baffle 9 squeezes the rubber support block 10 to produce elastic deformation, until the baffle 4 passes over the baffle 9, the rubber support block 10 rebounds and supports the baffle 9 to reset, and the baffle 9 blocks one side of the baffle 4 to prevent the baffle 4 from falling off the top rod body of the roller brush frame 1, and the roller brush body 2 is limited between the baffle 4 and the baffle 3; the reason why the slider 5 is fixed on the inner ring surface of the baffle 4 is that after the baffle 4 is installed on the top rod body of the roller brush frame 1, the slider 5 slides into the slide groove 6, thereby preventing the baffle 4 from rotating during the rotation of the roller brush body 2.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to prevent paint from sticking to hands when removing the roller brush body 2, the storage groove 12 is an annular groove, and a rubber ring 14 is fixed to one end of the flexible waterproof cover 13 extending out of the storage groove 12. After the flexible waterproof cover 13 is unfolded and sleeved on one end of the roller brush body 2, the rubber ring 14 is sleeved on one end of the roller brush body 2.

[0033] When the roller brush body 2 needs to be disassembled, first stretch the flexible waterproof cover 13 stored in the storage groove 12 and unfold it to be mounted on one end of the roller brush body 2, then pinch the two paddles 11 with two fingers respectively, and after the two fingers are closed, drive the corresponding block 9 to retract into the through-opening 8. At this time, the baffle 4 is no longer limited by the block 9, and then pinch the flexible waterproof cover 13 and press the roller brush body 2, and move the roller brush body 2 along the top rod of the roller brush frame 1 to pull it out. This operation can prevent the paint on the surface of the roller brush body 2 from sticking to the user's hands.

[0034] When in use, after the roller brush body 2 is sleeved on the top rod body of the roller brush frame 1, one end of the roller brush body 2 is blocked by the baffle 3, and then the baffle 4 is sleeved on the top rod of the roller brush frame 1, and the baffle 4 is pushed to slide along the top rod body of the roller brush frame 1. In this process, the baffle 4 squeezes the baffle 9 along the inclined surface, and the baffle 9 slides along the through-hole 8 under pressure, and the baffle 9 squeezes the rubber support block 10 to produce elastic deformation, until the baffle 4 passes over the baffle 9, the rubber support block 10 rebounds and supports the baffle 9 to reset, and the baffle 9 blocks one side of the baffle 4 to prevent the baffle 4 from falling off from the top rod body of the roller brush frame 1, and the roller brush body 2 is limited between the baffle 4 and the baffle 3; the reason why the slider 5 is fixed on the inner annular surface of the baffle 4 The purpose is to allow the slider 5 to slide into the slide groove 6 after the baffle 4 is installed on the top rod of the roller brush holder 1, thereby preventing the baffle 4 from rotating during the rotation of the roller brush body 2; when the roller brush body 2 needs to be disassembled, first, the flexible waterproof cover 13 stored in the storage groove 12 is stretched and unfolded to be mounted on one end of the roller brush body 2, and then two fingers are used to pinch the two paddles 11 respectively. After the two fingers are closed, the corresponding block 9 is driven to retract into the through-opening 8. At this time, the baffle 4 is no longer limited by the block 9, and then the flexible waterproof cover 13 is pinched by hand and the roller brush body 2 is pressed, and the roller brush body 2 is moved along the top rod of the roller brush holder 1 to be pulled out. This operation prevents the paint on the surface of the roller brush body 2 from sticking to the user's hands.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
