[0002] An inside corner plastering controller is a tool used in building construction to assist in plastering operations, especially when dealing with inside corners of walls. It can ensure the squareness and verticality of the plastering, improve construction quality and efficiency. In the field of building construction, inside corner plastering is an indispensable part of wall treatment, and its quality directly affects the overall aesthetics and durability of the wall. In existing corner plastering controllers, the sanding plate is a key component that comes into direct contact with the wall surface. It is used frequently and wears out quickly, so it needs to be replaced often. However, traditional controller designs often neglect the convenient disassembly and replacement of the sanding plate. The bolt or welding fixing method makes it necessary to spend a lot of time and effort when replacing the sanding plate, and even require the use of professional tools, which seriously affects the construction efficiency.

[0003] To address these issues, we provide a corner plastering controller. Utility Model Content

One end of the spring 204 is fixedly connected to the positioning post 202, and the other end is fixedly connected to the inner wall of the main board 101.

[0024] Further details: The main board 101 serves as the main support structure of the controller, bearing all other components and providing the main surface for contact with the wall. The sanding plate 102 is used for preliminary sanding or smoothing the wall surface during plastering. Multiple main boards 101 can be assembled together through the assembly unit 104 to increase the sanding area according to the sanding and plastering area. The handle 103 is provided for construction personnel to hold and operate the controller. The limit frame 201 is used to limit the movement range of the main board 101 to ensure the accuracy of installation. The positioning column 202 cooperates with the positioning groove 203 to achieve precise positioning and fixation between the main board 101 and the limit frame 201, thereby achieving the purpose of installing and disassembling the sanding plate 102. The spring 204 is used to provide elastic force so that the positioning column 202 can be tightly locked into the positioning groove 203, enhancing the stability and reliability of positioning.

[0025] Example 2 Please see Figures 1-5Based on embodiment 1, the mounting structure 2 further includes a pressing block 205, which is disposed at the upper and lower ends of the front of the main board 101. Sliding grooves 206 are provided on both sides of the front of the main board 101. A connecting plate 207 is slidably connected to the inner cavity of the sliding groove 206. The front and back of the connecting plate 207 are fixedly connected to the pressing block 205 and the positioning post 202, respectively. Movable blocks 208 are slidably connected to the upper and lower ends of the inner cavity of the rear end of the handle 103. A connecting post 209 is fixedly connected to one side of the pressing block 205. Limiting plates 210 are fixedly connected to one side of the pressing block 205 and to both sides of the connecting post 209. The ends of the connecting post 209 and the limiting plates 210 away from the pressing block 205 penetrate into the inner cavity of the handle 103 and are fixedly connected to the pressing block 205. A pull plate 211 is provided on the back of the handle 103. The top and bottom of the main body 1 are fixedly connected with connecting ropes 212. The end of the connecting rope 212 away from the pull plate 211 extends into the inner cavity of the handle 103 and is fixedly connected to the movable block 208. The upper and lower ends of the inner cavity on the back of the handle 103 are provided with guide wheels 213. The connecting rope 212 is slidably connected to the surface of the guide wheel 213. The main body 1 also includes an assembly unit 104. The assembly unit 104 includes an assembly groove 1041, an assembly plug 1043 and a positioning bolt 1042. The assembly groove 1041 is opened on both sides of the top of the main body 101. The assembly plug 1043 is fixedly connected to both sides of the bottom of the main body 101. The assembly plug 1043 is detachably connected to the inner cavity of the assembly groove 1041. The positioning bolt 1042 is set on the upper ends of both sides of the main body 101, and one end of the positioning bolt 1042 is threadedly connected to the inner cavity of the assembly plug 1043.

[0026] Further details: By pressing the pressing block 205, the connecting plate 207 slides within the sliding groove 206, thereby pushing the positioning column 202 out of the positioning groove 203, enabling quick assembly and disassembly of the grinding plate 102. The movable block 208, connecting column 209, limiting plate 210, and connecting rope 212 work together to achieve transmission between the pressing block 205 and the pulling plate 211. The guide wheel 213 guides the direction of the connecting rope 212 to ensure smooth transmission. Multiple main plates 101 can be assembled together through the assembly unit 104. By docking two main plates 101, the assembly insert 1043 is inserted into the inner cavity of the assembly groove 1041 and fixed with the positioning bolt 1042, thus achieving the purpose of splicing and use, so as to increase the grinding area according to the grinding and plastering area.

[0027] The working principle of this utility model is as follows: the operator can operate the main board 101 and the grinding plate 102 by holding the handle 103 to perform plastering work at the inside corner. When the grinding plate 102 is worn out and needs to be replaced, the two pressing blocks 205 can be pressed at the same time, or the pulling plate 211 can be hooked and pulled forward. Both methods will cause the pressing blocks 205 to move the positioning pin 202 in conjunction with the connecting plate 207. After the positioning pin 202 moves out of the inner cavity of the positioning groove 203, the positioning effect between the main board 101 and the grinding plate 102 can be released. At this time, the old grinding plate 102 can be removed and replaced with a new one. After the replacement is completed, the pressing blocks 205 are released. At this time, under the action of the spring 204, the positioning pin 202 re-enters the inner cavity of the positioning groove 203 and engages with it, so that the main board 101 and the grinding plate 102 can be repositioned.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
