[0025] The threaded rod 21 penetrates the shell 1 and is threadedly connected. The end of the threaded rod 21 located on the outside of the shell 1 penetrates and is fixedly connected with a round block 22. The distance between the auxiliary roller 27 and the main roller 214 is adjusted by rotating the round block 22 and the threaded rod 21, so that latex paints of different properties can be more evenly bonded to the surface of the main roller 214 with the assistance of the auxiliary roller 27, and the auxiliary roller 27 can play an auxiliary role when painting. The threaded rod 21 is located on the inner side of the shell 1. One end penetrates and is rotatably connected with a block 23. The surface of the block 23 penetrates and is hinged with a hinged rod 24. The end of the hinged rod 24 away from the block 23 penetrates and is hinged with a pulling block 25. The surface of the pulling block 25 is fixedly connected with a support plate 26. The support plate 26 The surface of the housing 1 is penetrated and rotatably connected with a secondary roller 27, the rotating round block 22 drives the threaded rod 21 to rotate, so that the threaded rod 21 moves toward the outside of the housing 1, and the threaded rod 21 pulls the square block 23, and the square block 23 drives the pulling block 25 to move toward the middle along the guide rod 28 through the hinge rod 24, so that the pulling block 25 drives the supporting plate 26 to shorten the distance between the secondary roller 27 and the main roller 214, the movable chamber 210 is opened on the inner side of the housing 1 and the housing 2 3, and the movable chamber 210 is slidably connected with a U-shaped frame 211, the inner side of the movable chamber 210 is provided with a square groove 212, the inner side of the square groove 212 is fixedly connected with a spring 213, and the end of the spring 213 away from the square groove 212 is fixedly connected to the surface of the U-shaped frame 211.

When the clip bar 221 contacts the latching tooth 217, the hinged position of the rotating plate 220 and the hinge block 219 will rotate, and the torsion spring 224 will be compressed. After the clip bar 221 exceeds the latching tooth 217, the torsion spring 224 will push the rotating plate 220 to clamp the clip bar 221 and the latching tooth 217, so that the slide plate 216 is temporarily fixed. The inner side of the slide groove 215 is penetrated and slidably connected with the slide plate 216. Before painting the wall, the staff can first contact the push block 218, so that the push block 218 drives the slide plate 216 to slide along the slide groove 215, so that the slide plate 216 drives the rotating plate 220 to slide together through the hinge block 219, and the top surface of the slide plate 216 is fixedly connected with the push block 218.The bottom surface of the slide plate 216 is fixedly connected with a hinge block 219, the inner side of the hinge block 219 is hinged with a rotating plate 220, the bottom surface of the rotating plate 220 is fixedly connected with a clamping strip 221, and a torsion spring 224 is fixedly connected between the rotating plate 220 and the slide plate 216. A pressing rod 222 is penetrated and slidably connected to the inner side of the slide plate 216, and a push rod 223 is fixedly connected to the bottom surface of the slide plate 216. The pressing rod 222 is pressed downward to make the pressing rod 222 contact the rotating plate 220 and force the rotating plate 220 to rotate, so that the clamping strip 221 and the clamping teeth 217 are no longer engaged, and the tightened spring 213 will pull the U-shaped frame 211 back, and at the same time, the U-shaped frame 211 will drive the slide plate 216 to reset through the push rod 223, so that the main roller 214 is reset to the inner side of the shell 1 and the shell 23, and the end of the push rod 223 close to the U-shaped frame 211 is fixedly connected to the surface of the U-shaped frame 211.

[0026] Based on the above embodiment, before painting the wall, the staff can first contact the pushing block 218, so that the pushing block 218 drives the slide plate 216 to slide along the slide groove 215, and the slide plate 216 drives the rotating plate 220 to slide together through the hinge block 219, and when the rotating plate 220 slides, it will drive the clamping strip 221 to contact the clamping tooth 217, and when the clamping strip 221 contacts the clamping tooth 217, the hinged position of the rotating plate 220 and the hinge block 219 will rotate, and the torsion spring 224 will be compressed, and after the clamping strip 221 exceeds the clamping tooth 217, the torsion spring 224 will push the rotating plate 220 to clamp the clamping strip 221 and the clamping tooth 217, so that The slide plate 216 is temporarily fixed, and in the process of the slide plate 216 being pushed by the push block 218, the push rod 223 is driven to push the U-shaped frame 211 to slide in the movable chamber 210. When the U-shaped frame 211 slides in the movable chamber 210, it will not only stretch the spring 213, but also drive the main roller 214 to extend a certain distance, and then the main roller 214 is extended into the latex paint by grabbing or controlling the connecting handle 4, so that the latex paint is attached to the main roller 214, and after the connecting handle 4 is shaken to shake off the excess latex paint on the main roller 214, the pressing rod 222 is pressed downward to make the pressing rod 222 contact the rotating plate 220 and force the rotating plate 220 to rotate, so that The card strip 221 and the card tooth 217 are no longer engaged, and the tightened spring 213 will pull the U-shaped frame 211 back. At the same time, the U-shaped frame 211 will drive the slide plate 216 to reset through the push rod 223, so that the main roller 214 is reset to the inner side of the shell 1 and the shell 2 3, and then observe the distance between the main roller 214 and the auxiliary roller 27. If the distance between the main roller 214 and the auxiliary roller 27 is large, the round block 22 can be rotated to drive the threaded rod 21 to rotate, so that the threaded rod 21 moves toward the outside of the shell 1, and the threaded rod 21 will pull the square block 23, and the square block 23 will drive the pulling block 25 to move toward the middle along the guide rod 28 through the hinged rod 24, and then the main roller 214 and the auxiliary roller 27 will be reset. The pulling block 25 drives the supporting plate 26 to shorten the distance between the auxiliary roller 27 and the main roller 214, so that the latex paint on the surface of the main roller 214 can be fitted with the auxiliary roller 27. During painting or quick painting, after the latex paint on the surface of the main roller 214 fits the wall, the rolling hair on the surface of the main roller 214 is squeezed, and a part of the latex paint will slide onto the auxiliary roller 27 under the rotation of the main roller 214. If some relatively viscous latex paint is encountered, the rotation of the main roller 214 can also produce a certain degree of squeezing on the latex paint under the fitting of the auxiliary roller 27, so that the latex paint attached to the surface of the main roller 214 is more uniform and avoids dripping.

[0027] At the same time, according to the properties of latex paints of different properties, such as water-based, oil-based, direct brush paint or blended paint, the distance between the auxiliary roller 27 and the main roller 214 can be adjusted by rotating the round block 22 and the threaded rod 21, so that latex paints of different properties can be assisted by the auxiliary roller 27 to make the latex paint on the surface of the main roller 214 fit more evenly, and the auxiliary roller 27 can play an auxiliary role in painting. With the angle of the entire shell 1 and the shell 2 3 controlled by the connecting handle 4, it is possible to arbitrarily control whether the auxiliary roller 27 is fitted to the wall. It has a wide adaptability and is more flexible and convenient to operate.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
