[0027] Embodiment 3:

[0028] This embodiment specifically introduces the usage of the utility model:

[0029] When in use, the flat surface of the external wall can be plastered by the straight scraper 4; when the curved surface of the external wall needs to be plastered, a set of worms 104 is rotated by the knob, and two sets of symmetrical worms 104 are rotated simultaneously through the connecting shaft 105, and the two sets of symmetrical worms 104 drive two sets of control rods 201 to rotate in opposite directions inside the support block 103 through two sets of symmetrical worm wheels 203. The two sets of control rods 201 drive the driving gears 202 at both ends to rotate respectively, and the driving gears 202 drive the sliding flat teeth 303 to slide inside the fixed bracket 301. At the same time, because the two sets of sliding flat teeth 303 are fixed to the two sides of the scraper 4 through the connecting block 304, when the driving gear 202 rotates, the length of the sliding flat teeth 303 between the two sets of fixed brackets 301 increases, so that the two sides of the scraper 4 are folded inward at the same time, thereby reducing the curvature of the circular arc surface of the scraper 4, and vice versa, the curvature of the circular arc surface of the scraper 4 can be increased. And because the travel of the driving gears 202 on both sides is consistent, the arc surface of the scraper 4 can be uniformly changed, which is beneficial to adjust the curvature of the scraper 4 according to the curvature of the arc surface of the exterior wall, and is beneficial to ensure the flatness of the arc surface when plastering.

[0030] The plastering tool of the utility model can be used for construction of external corners / internal corners of different curvatures. When the curvature bending direction of the scraper 4 and the construction of the external corner and the internal corner need to be changed, a manual assisted thrust can be given to the scraper 4 in the direction in which the scraper 4 needs to be bent, so that the bending direction of the scraper 4 is bent in the thrust direction, so that the bending direction of the scraper 4 is changed, and then the internal corner and the external corner of the wall can be plastered respectively.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
