[0016] The following will be combined with specific embodiments and attached Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0017] A waterproof brushing device for tension bolt holes on an exterior wall comprises a handheld power device 1, a hopper transmission device 2 and a roller brushing device 3.

[0018] The handheld power device 1 includes a handheld shell 11, which is wide at the top and narrow at the bottom. The narrow part at the bottom is convenient for single-handed holding. One side of the handheld shell 11 is rotatably connected to a rotating handle 12. The rotating handle 12 is arranged on the narrow side, which is convenient for fingers to apply force to drive the rotating handle 12 when holding. A spring 13 is arranged in the middle of the rotating handle 12, and the other end of the spring 13 is connected to the handheld shell 11. When the rotating handle 12 is held and pressed down, the spring 13 is compressed. When the force applied to the rotating handle 12 by the hand is removed, the rotating handle 12 will be ejected under the action of the elastic force of the spring 13 and return to its original state. The other end of the rotating handle 12 is rotatably connected to a transmission rod 14, and the inside of the handheld shell 11 is rotatably connected to a non The concentric fixed gear 15 and the transmission rod 14 are rotationally connected to the non-center portion of the side of the non-concentric fixed gear 15. When the user holds the rotating handle 12 tightly and makes the rotating handle 12 approach the handheld housing 11, the rotating handle 12 drives the transmission rod 14 to move, and the movement of the transmission rod 14 will be transmitted to the non-concentric fixed gear 15. Because the transmission rod 14 is rotationally connected to the non-center portion of the non-concentric fixed gear 15, the movement of the rotating rod will be applied to the non-concentric fixed gear 15, causing the non-concentric fixed gear 15 to rotate. Hold the rotating handle 12 tightly and then release it. The spring 13 returns the rotating handle 12 to its initial position, which just corresponds to one rotation of the non-concentric fixed gear 15. Repeated holding can make the non-concentric fixed gear 15 rotate continuously. When the spring 13 is fully extended, the center of the non-concentric fixed gear 15 is located above the straight line where the transmission rod 14 is located, and the connection point between the transmission rod 14 and the non-concentric fixed gear 15 is located to the left of the lower part of the non-concentric fixed gear 15. The rotating handle 12 is held firmly to drive the transmission rod 14 to rotate the non-concentric fixed gear 15 half a circle, so that the connection point between the transmission rod 14 and the non-concentric fixed gear 15 is rotated to the right of the upper part of the center of the circle. Then, under the action of inertia, the non-concentric fixed gear 15 continues to rotate, and at the same time, the spring 13 rebounds, driving the transmission rod 14 to make the non-concentric fixed gear 15 continue to rotate, completing one rotation, and so on, thus generating a continuous source of power.

[0019] The non-concentric fixed gear 15 is transmission-connected to a gear set 16, which includes a first gear ratio gear 161, a second gear ratio gear 163 and a direction-changing gear 162. The first gear ratio gear 161 and the second gear ratio gear 163 are both commonly used components in the prior art, and are formed by a large-sized gear and a small-sized gear being concentrically fixedly connected. The first gear ratio gear 161, the second gear ratio gear 163 and the direction-changing gear 162 are all rotationally connected inside the handheld housing 11, wherein the small-sized gear of the first gear ratio gear 161 is meshed with the non-concentric fixed gear 15, the large-sized gear of the first gear ratio gear 161 is meshed with the direction-changing gear 162, and the direction-changing gear 162 is meshed with the large gear of the second gear ratio gear 163. Through the mutual meshing of the gears, the power generated by the non-concentric fixed gear 15 is transmitted to the second gear ratio gear 163.

[0020] A hopper transmission device 2 is provided on one side of the handheld housing 11, and the hopper transmission device 2 includes a hinge cage 21, and the hinge cage 21 is fixedly connected to one side of the handheld housing 11. A hopper 22 is fixedly connected to the top of the hinge cage 21. A screw conveying rod 23 is rotatably connected in the hinge cage 21, and the screw conveying rod 23 is transmission-connected to the gear set 16. Specifically, one end of the screw conveying rod 23 penetrates into the interior of the handheld housing 11, and the screw conveying rod 23 is rotatably connected relative to the handheld housing 11. The end portion of 23 located in the handheld housing 11 is fixedly connected with a conveying gear 231, and the conveying gear 231 is meshed with the small-sized gear of the second gear ratio gear 163. The conveying gear 231 can be driven by the second gear ratio gear 163. When the waterproof coating is added into the hopper 22, the finger drives the rotating handle 12 to rotate, and the rotating handle 12 drives the non-concentric fixed nail gear to rotate. The rotation of the non-concentric fixed gear 15 finally drives the spiral conveying rod 23 through the gear seat, so that the spiral conveying rod 23 conveys the waterproof coating along the hinge cage 21.

[0021] A roller brushing device 3 is provided at the end of the hopper transmission device 2, and the roller brushing device 3 includes a feeding pipe 31, and the feeding pipe 31 is vertically arranged with the spiral conveying rod 23, and the feeding pipe 31 is fixedly connected with the spiral conveying rod 23 through a material collection interface 33, and the material collection interface 33 is rotatably connected with the hinge cage 21, and the waterproof coating conveyed by the hopper transmission device 2 will be collected and conveyed to the feeding pipe 31 through the material collection interface 33, and a roller 32 is arranged on the outer sleeve of the feeding pipe 31, and the roller 32 is coaxial with the feeding pipe 31, so the roller 32 and the spiral conveying rod 23 are also perpendicular to each other, and the internal space of the roller 32 is connected with the feeding pipe 31, and the waterproof coating flows from the feeding pipe 31 into the roller 32, and the roller 32 is provided with a A large number of meshes, the rotation of the spiral feed pipe 31 will drive the feed pipe 31 to rotate together, and the feed pipe 31 will also drive the roller 32 to rotate. As the roller 32 rotates, the waterproof coating flows out from the meshes, and adheres to the wall surface as the roller 32 rotates, so that the waterproof coating is applied. Because the rotation speed of the roller 32 is uniform, the force applied to the wall surface is also uniform, so the wall waterproof coating will also present a flat and smooth effect, which is better than the effect of manual brushing. At the same time, the roller 32 is rotatably connected relative to the feed pipe 31. While the roller 32 is driven by the feed pipe 31 to rotate, it will also rotate due to the friction with the wall surface, so that the roller 32 on the roller 32 is parallel to the plane where the handheld shell 11 is located.

[0022] A protective cover 34 is fixedly connected to the first end of the cage 21 near the roller 32. The protective cover 34 is conical and can prevent the waterproof paint overflowing from the roller 32 from spilling and contaminating the wall. A fixed ring 35 is fixedly connected to the end of the protective cover 34. The inner radius of the fixed ring 35 is the same as the length of the roller 32. The fixed ring 35 can prevent excess paint from flowing down the wall surface and causing waste. The waterproof paint can be confined in the protective cover 34 and applied to the wall surface through the roller 32 to form a regular circle, which is more beautiful and does not cause waste.

[0023] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0024] In the present utility model, "up", "down", "left", "right", "front" and "back" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.
