The rotating shaft and the axial hole are rotatably connected to the protrusion in a hemispherical shape. The plane of the protrusion is fixedly connected to the bottom of the card plate 14, and the spherical surface of the protrusion faces away from the card plate 14. The mounting hole 12 and the protrusion cooperate with each other to form a folding plate structure with a W-shaped cross section, and the second shaping plate 11 forms a folding plate structure with an L-shaped cross section. In this scheme, it should be noted that this scheme is suitable for interior decoration and needs to be used in conjunction with manual labor. It is not an automated equipment suitable for a large area. By setting the first shaping plate The first shaping plate 10 is used to trim the positive corner of the wall by using the bent portion at the bottom of the first shaping plate 10, such as plastering or diatom mud construction. After the second shaping plate 11 is installed with the first shaping plate 10, a right angle of ninety degrees is formed by the second shaping plate 11 and the bottom and side wall of the first shaping plate 10. The negative corner of the wall is trimmed by the community formed by the first shaping plate 10 and the second shaping plate 11. When installing the first shaping plate 10, first rotate the clamping plate 14 to one side of the ear plate 13, and place the second shaping plate 11 at the bottom of the first shaping plate 10. At the corner, rotate the card plate 14 to move it to the top of the first shaping plate 10. Since the card plate 14 has a certain elastic deformation ability, the card plate 14 is made of steel. The protrusion at the bottom of the card plate 14 is inserted into the mounting hole 12 to lock and fix the second shaping plate 11. The four corners of the second shaping plate 11 can be connected to the first shaping plate 10, thereby ensuring the firm connection of the first shaping plate 10. When scraping, the second shaping plate 11 is not easy to loosen and fall off. When installing the second shaping plate 11, it is simple and quick, and easy to disassemble and assemble, which is helpful for construction.

[0034] like Figure 1 , Figure 5 and Figure 6As shown, the handle structure is arranged on one side of the first shaping plate 10 and can be flipped to adjust the holding posture. The handle structure includes a holding rod body 20, a limiting sleeve 21, a positioning retaining ring 22 and a thrust hole 23. The holding rod body 20 is rotatably connected to the positioning retaining ring 22, the positioning retaining ring 22 is fixedly connected to the first shaping plate 10, the limiting sleeve 21 is elastically connected to the holding rod body 20, a plurality of thrust holes 23 are arranged on the wall surface of the positioning retaining ring 22, and a card block is arranged at the bottom of the limiting sleeve 21, which can be inserted into the stopper. The position of the holding rod body 20 is locked in the push hole 23, and the holding rod body 20 forms a bent L-shaped rod structure. The vertical part of the holding rod body 20 is rotatably connected with the positioning retaining ring 22. The positioning retaining ring 22 is annular, and the holding rod body 20 is provided with a sliding groove. The limiting sleeve 21 is annular, and a stopper is fixedly connected to the inner wall of the limiting sleeve 21. The stopper is slidably connected to the vertical groove. A spring is fixedly installed on the wall surface of the holding rod body 20, and the spring contacts the upper end surface of the limiting sleeve 21. The stopper and the limiting sleeve 21 are integrally formed. The stopper is a rectangular block structure, and the thrust hole 23 is adapted to the stopper. In this solution, as a supplement to the above solution, by setting the gripping rod body 20, the gripping rod body 20 is used to facilitate the gripping and exerting force of the hand. When scraping the plaster along the vertical direction of the wall, the limit sleeve 21 can be pushed up, and the stopper of the limit sleeve 21 slides in the slide groove and squeezes the elastic member, and the block is separated from the thrust hole 23. After the gripping rod body 20 is rotated to adjust the position of the gripping rod body 20, the limit sleeve 21 is released, and the limit The sleeve 21 falls down and resets, and the block at the bottom of the limit sleeve 21 is inserted into another thrust hole 23. The angle between two adjacent thrust holes 23 is ninety degrees for example, and the orientation of the holding rod 20 can be adjusted to adjust the holding method. It can be used for vertical scraping or horizontal scraping. Vertical scraping means that the convex rib of the second shaping plate 11 slides along the corner of the wall, and horizontal scraping means that the second shaping plate 11 scrapes the plaster from one wall to another vertical wall to collect the plaster. I will not go into details here.

The angle between two adjacent thrust holes 23 is ninety degrees, for example, and the direction of the holding rod body 20 can be adjusted to adjust the holding method, and it can be used for scraping the wall in the vertical direction or horizontally.

[0036] By setting the first shaping plate 10, the bending part at the bottom of the first shaping plate 10 is used to trim the positive corner of the wall, such as plastering or diatom mud construction, and after the second shaping plate 11 is installed with the first shaping plate 10, the second shaping plate 11 and the bottom and side wall of the first shaping plate 10 form a right angle of 90 degrees, and the community formed by the first shaping plate 10 and the second shaping plate 11 is used to trim the negative corner of the wall, and when installing the first shaping plate 10, the card plate 14 is first rotated to the ear plate On one side of 13, the second shaping plate 11 is placed at the corner at the bottom of the first shaping plate 10, and the card plate 14 is rotated to make the card plate 14 move to the top of the first shaping plate 10. Since the card plate 14 has a certain elastic deformation ability, the card plate 14 is made of steel. The protrusion at the bottom of the card plate 14 is inserted into the mounting hole 12 to achieve locking and fixing of the second shaping plate 11. The four corners of the second shaping plate 11 can be connected to the first shaping plate 10, thereby ensuring the firm connection of the first shaping plate 10.
