Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 3 As shown, a plastering device for building decoration includes a scraper body 1. Support plates 2 are fixedly connected to both sides of one edge of the scraper body 1. Connecting discs 3 are fixedly connected to the ends of the two support plates 2 away from the scraper body 1. A rotating shaft 4 is rotatably connected to the center of the two connecting discs 3. A connecting strip 7 is fixedly connected to the middle of the rotating shaft 4. A connecting frame 8 is fixedly connected to one side of the connecting strip 7. Press handles 9 are fixedly connected to both sides of the connecting frame 8 and both sides of the connecting strip 7. Spring connecting plates 5 are fixedly connected to both ends of the rotating shaft 4. Coil springs 6 are sleeved on both sides of the rotating shaft 4. The two ends of the coil springs 6 are fixedly connected to the connecting discs 3 and the spring connecting plates 5, respectively. Indicator needles 10 are fixedly connected to both sides of the rotating shaft 4 near the connecting discs 3. Angle dials 11 are fixedly connected to the edges of the two connecting discs 3 facing each other. The indicator needles 10 correspond to the surface of the angle dials 11. The rotating shaft 4 drives the connecting frame 8 to rotate away from the scraper body 1 under the action of the coil springs 6.

[0023] As an optional technical solution of this utility model, an auxiliary support rod 12 is fixedly connected to the middle of the connecting strip 7. A spring fixing seat 13 is fixedly connected to the end of the auxiliary support rod 12 away from the connecting strip 7. A reset support spring 14 is fixedly connected to the bottom of the inner wall of the spring fixing seat 13. The bottom of the reset support spring 14 contacts one side of the scraper plate 1. By pushing the auxiliary support rod 12 and the spring fixing seat 13 to flip and reset through the reset support spring 14, a clamping force can be provided at the center, improving the uniformity of the clamping force distribution.

[0024] As an optional technical solution of this utility model, two retaining rings 15 are fixedly connected to both sides of one side edge of the scraper body 1. The two retaining rings 15 are respectively sleeved on both sides of the connecting frame 8. The two retaining rings 15 are used to restrict the upward flipping of the connecting frame 8. By restricting the flipping stroke of the connecting frame 8 through the retaining rings 15, the pressing handle 9 is controlled in a suitable position, so that the pressing handle 9 and the scraper body 1 are at a suitable operating angle, so as to facilitate the pushing operation.

[0025] As an optional technical solution of this utility model, the auxiliary support rod 12 and the connecting frame 8 are on the same plane, and the auxiliary support rod 12 and the connecting frame 8 are arranged parallel to each other on both sides. The width of the connecting frame 8 is adapted to the width of the scraper plate 1, and the length of the connecting frame 8 is adapted to the length of the scraper plate 1, so that the connecting frame 8 and the auxiliary support rod 12 rotate synchronously, thereby allowing the reset pushing force of the reset support spring 14 and the coiling force of the coil spring 6 to be released synchronously.

[0026] As an optional technical solution of this utility model, the two pressing handles 9 are symmetrically arranged with the auxiliary support rod 12 as the center, so that the pressing force on both sides is evenly distributed when pressing with both hands.

[0027] The following steps are required when using this plastering device for architectural decoration:

[0028] 1) By pressing down the handle 9, the angle dial 11 and the support plate 2 are flipped towards the wall by the retraction of the coil spring 6, so that the scraper plate 1 can be pressed against the wall and scraped.

[0029] 2) By observing the angle of the dial 11 indicated by the indicator needle 10, the pressure level on the wall can be determined, so as to accurately control the plastering pressure;

[0030] 3) Then push and scrape it flat.

[0031] In summary, by pressing down the handle 9, the spring 6 rewinds, causing the angle dial 11 and support plate 2 to flip towards the wall, allowing the scraper plate 1 to press against the wall and scrape. Simultaneously, by observing the angle of the angle dial 11 indicated by the pointer 10, the pressure level on the wall can be determined, enabling precise control of the scraping pressure and improving the smoothness of the scraping. The retaining ring 15 limits the flipping stroke of the connecting frame 8, ensuring that the handle 9 is controlled in a suitable position, and that the handle 9 and scraper plate 1 are at a suitable operating angle for easy operation.
