[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 , Figure 2 A corner plastering tool includes a pair of plastering boards 1, wherein a support pipe 2 is fixedly connected to the middle of the side wall of one plastering board 1, and a receiving pipe 3 is fixedly connected to both ends of the side wall of the other plastering board 1, and the support pipe 2 can be inserted between the two receiving pipes 3.

[0020] Reference Figure 1 , Figure 2 A support shaft 4 is provided between the two receiving pipes 3. The support pipe 2 is rotatably sleeved on the support shaft 4, meaning that the support pipe 2 can rotate around the support shaft 4, thereby adjusting the included angle between the two plastering boards 1. At the same time, a limiting member 5 is provided between the support shaft 4 and the support pipe 2 to restrict the rotation of the support pipe 2.

[0021] In this embodiment, the plastering tool can be adapted to different angles of inside and outside corners because the included angle between a pair of plastering boards 1 can be adjusted, thereby improving the adaptability of the plastering tool.

[0022] Reference Figure 2 , Figure 3 The limiting component 5 includes a limiting screw 51 threaded through the support tube 2. The support shaft 4 has multiple limiting grooves 52. The multiple limiting grooves 52 are arranged at equal intervals along the circumference of the support shaft 4, and the limiting screw 51 can be threaded into any limiting groove 52 to achieve quick fixation of the support shaft 4 and the support tube 2.

[0023] Reference Figure 3 The support shaft 4 includes a support round shaft 41, a support tube 2 is rotatably sleeved on the support round shaft 41, and a limiting groove 52 is opened on the circumferential side wall of the support round shaft 41. The top end of the support round shaft 41 is fixedly connected to a first square shaft 42 and the bottom end is fixedly connected to a second square shaft 43. The first square shaft 42 and the second square shaft 43 are respectively inserted into the corresponding receiving tube 3, and the inner surface of the receiving tube 3 matches the circumferential surface of the first square shaft 42 or the second square shaft 43.

[0024] Reference Figure 3 The length of the diagonal of the first square shaft 42 is greater than the diameter of the supporting round shaft 41, and the length of the diagonal of the second square shaft 43 is less than the diameter of the supporting round shaft 41. That is, the supporting shaft 4 is a stepped shaft. This design allows the supporting shaft 4 to be pulled out so that a pair of plastering boards 1 can be separated.

[0025] In this embodiment, the support shaft 4 and the pair of plastering boards 1 are separate structures. The pair of plastering boards 1 can be disassembled to facilitate the grinding, repair, maintenance, or replacement of the plastering boards 1 by construction personnel, thereby improving operational convenience. At the same time, the limiting component 5 can not only fix the support tube 2 and the support shaft 4, but also limit the connection between the support shaft 4 and the pair of plastering boards 1. That is, no additional locking component is needed between the receiving tube 3 and the first square shaft 42 and the second square shaft 43, saving costs.

[0026] Reference Figure 3A flexible anti-reverse ring 6 is fixedly connected to the second square shaft 43, and an anti-reverse groove 7 is provided on the inner wall of the receiving pipe 3 for the anti-reverse ring 6 to be engaged. When the operator loosens the limiting screw 51 and the first square shaft 42 is located below, this design can prevent the support shaft 4 from slipping and improve the stability of use.

[0027] Reference Figure 1 , Figure 3 A lifting ring 8 is fixedly connected to the support pipe 2, allowing the worker's fingers to pass through, so as to facilitate the operation of the plastering work. At the same time, the lifting ring 8 is set on the support pipe 2, so that the worker's working force can be applied to the middle position of the plastering tool, which improves the balance of the plastering tool and makes it more comfortable for the worker to use.

[0028] Reference Figure 1 Each of the two plasterboards 1 has an anti-wear layer on its surface to improve the wear resistance of the plasterboards 1, reduce the risk of wear and tear, and thus ensure the quality of construction.
