[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1 Please see Figures 1-6 This utility model is a corner plastering controller, including an outer frame 1. The inner cavity of the outer frame 1 is provided with two first grinding plates 2. An assembly 3 is provided on one side of the first grinding plate 2, and a connecting component 4 is provided on the surface of the outer frame 1. The assembly 3 is used to assemble with the first grinding plate 2, and can increase the grinding and plastering area according to the grinding and plastering area. The assembly 3 includes a second grinding plate 31, and a retaining strip 32 is fixedly connected to one side of the second grinding plate 31. A retaining groove 33 is opened on one side of the first grinding plate 2. The connecting component 4 is used to fix and disassemble the first grinding plate 2. The connecting component 4 includes a T-shaped plate 41, and the T-shaped plate 41 is fixedly connected to the first grinding plate 2. A T-shaped groove 42 is opened in the inner cavity of the outer frame 1. A positioning hole 43 is opened on one side of the T-shaped plate 41, and a bolt 44 is threadedly connected to the surface of the outer frame 1.

[0024] Further details: According to actual needs, the first grinding plate 2 and the second grinding plate 31 can be assembled onto the outer frame 1 by engaging the locking strip 32 and the locking groove 33 to form the required grinding and plastering area. By engaging the second grinding plate 31 with the first grinding plate 2, the grinding and plastering area can be easily increased or decreased according to actual needs, improving the flexibility and applicability of the tool. Then, by cooperating the T-shaped plate 41 with the T-shaped groove 42 and tightening the bolt 44 with the positioning hole 43, the stability of the first grinding plate 2 and the second grinding plate 31 during operation is ensured. At the same time, the design of the connecting component 4 allows the two first grinding plates 2 to be quickly and easily disassembled and assembled when worn, facilitating maintenance and replacement.

[0025] Example 2 Please see Figures 1-6 Based on embodiment 1, one end of the clip 32 extends into the inner cavity of the slot 33 and engages with the inner cavity of the slot 33; one end of the bolt 44 extends into the inner cavity of the positioning hole 43 and is movably connected to the inner cavity of the positioning hole 43; the T-shaped plate 41 is located in the inner cavity of the T-shaped groove 42 and is movably connected to the inner cavity of the T-shaped groove 42; a first magnet 411 is fixedly connected to the bottom of the T-shaped plate 41, and a second magnet 421 is fixedly connected to the bottom of the inner cavity of the T-shaped groove 42; the first magnet 411 and the second magnet 421 are in contact with each other and are magnetically connected; a handle 12 is fixedly connected to the surface of the outer frame 1, and an anti-slip sleeve is fitted on the surface of the handle 12; a sealing strip is fixedly connected to one side of the second grinding plate 31, and the side of the sealing strip away from the second grinding plate 31 is in contact with the first grinding plate 2.

[0026] Further details: The snap-fit ​​structure between the clip 32 and the slot 33 ensures a stable connection between the first grinding plate 2 and the second grinding plate 31, preventing them from separating or loosening during grinding and plastering, while also improving ease of assembly and disassembly. The magnetic connection between the first magnet 411 and the second magnet 421 enhances the connection stability between the T-shaped plate 41 and the T-shaped slot 42, providing additional fixing force for the first grinding plate 2 and ensuring stability during grinding and plastering. The design of the handle 12 and anti-slip sleeve provides a comfortable grip for the operator, reducing fatigue from prolonged work. The anti-slip sleeve increases the friction of the handle 12, preventing the tool from slipping or causing accidents during operation. The sealing strip design on one side of the second grinding plate 31 ensures that the second grinding plate 31 and the first grinding plate 2 are flush and seamless, thereby improving the consistency and uniformity of the grinding and plastering effect and ensuring the flatness and aesthetics of the external corner plastering.

[0027] The working principle of this utility model is as follows: First, the first grinding plate 2 is placed into the inner cavity of the outer frame 1, ensuring that the T-shaped plate 41 is aligned with the T-shaped groove 42. Then, according to the actual grinding and plastering area requirements, the second grinding plate 31 is assembled onto the first grinding plate 2 through the snap-fit ​​connection between the clip 32 and the groove 33, forming the required grinding and plastering area. Afterwards, by rotating the bolt 44, one end of the bolt 44 will gradually move to one side and screw into the positioning hole 43, fixing the first grinding plate 2 onto the outer frame 1, thus realizing the installation operation. During grinding and plastering, by holding the handle 12, the device can be moved to the area to be ground and plastered, so that the first grinding plate 2 and the second grinding plate 31 can be aligned. The grinding plate 31 contacts the wall surface for grinding and plastering. After grinding and plastering are completed, personnel can check whether the first grinding plate 2 and the second grinding plate 31 are damaged. If damaged, personnel can pull the second grinding plate 31, which will cause the retaining strip 32 to disengage from the inner cavity of the retaining groove 33, thereby disassembling the second grinding plate 31 for easy replacement later. At the same time, personnel can reverse the bolt 44, which will cause one end of the bolt 44 to gradually disengage from the inner cavity of the positioning hole 43. Then, by pulling the first grinding plate 2, the first grinding plate 2 will cause the T-shaped plate 41 to gradually disengage from the inner cavity of the T-shaped groove 42, thereby disassembling the first grinding plate 2 for easy replacement later.
