Before roller coating, pulling the pull ring causes the limiting post to slide in the cylindrical tube and exit from the limiting hole. The pull ring causes the return spring to stretch, pulling the sliding sleeve to slide on the surface of the handheld rod. When the sliding sleeve slides, it drives two L-shaped plates and rollers to rotate upward relative to the connecting plate through two rotating rods. After the two L-shaped plates and rollers rotate to a suitable height, the handheld rod is held to place the roller coating mechanism into the paint bucket. The upward rotation of the two L-shaped plates and rollers avoids contact with the paint in the paint bucket. During roller coating, the sliding sleeve is pushed... The sliding sleeve slides on the surface of the handheld rod. When the sliding sleeve slides, it drives two L-shaped plates and rollers to rotate relative to the connecting plate through two rotating rods. When the two L-shaped plates rotate to the same line as the connecting plate, two limiting plates restrict the rotation of the two L-shaped plates. When the pull ring is released, the return spring retracts and drives the limiting post to slide in the cylindrical tube through the pull ring and connect with the limiting hole, thereby fixing the position of the sliding sleeve. The sliding sleeve restricts the rotation of the two L-shaped plates through two rotating rods, pushes the handheld rod to drive the roller coating mechanism to perform roller coating work and drive the two rollers to rotate. The two rollers can restrict the movement direction of the roller coating mechanism to avoid the roller coating direction of the roller coating mechanism from deviating, improve the quality of the roller coating of the roller coating surface, and improve the adaptability of the device.

[0017] 2. This utility model provides a handheld roller coating device, which employs a roller coating mechanism, a base plate, a protective cover, a support plate, a connecting rod, a connecting shaft, paint rollers, nuts, a connecting seat, and a second nut. Before use, one end of the handheld rod is inserted into the connecting seat and the second nut is rotated, which fixes the handheld rod and the connecting seat, thus connecting the handheld rod and the roller coating mechanism as a whole. During roller coating, the handheld rod is used to place the entire roller coating mechanism into the paint bucket, making the two paint rollers contact with the paint. After the two paint rollers have made full contact with the paint, the handheld rod is pulled to remove the entire roller coating mechanism from the paint bucket. The handheld rod drives the entire roller coating mechanism to move, making the two paint rollers contact the coating surface. Pushing the handheld rod drives the two paint rollers to rotate, coating the surface. The two protective covers are connected to the base plate to prevent paint from falling from the paint rollers and causing injury to the worker. During roller coating, the two paint rollers drive the two connecting rods to rotate relative to the two support plates through the two connecting shafts, so that the two paint rollers continuously contact the coating surface, improving the roller coating efficiency and enhancing the adaptability of the device.
