[0030] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a plaster scraper for building decoration engineering, comprising a mounting seat 1 and a scraper 2, a plug plate 3 is fixedly connected to the bottom of the scraper 2, the plug plate 3 is inside the mounting seat 1, a pull rod 4 is arranged in the middle of the outer wall of the mounting seat 1, a support rod 5 is fixedly connected to one side of the pull rod 4, a plug rod 6 is fixedly connected to one side of the support rod 5, the plug rod 6 and the support rod 5 are both slidably connected to the inside of the mounting seat 1, and the plug rod 6 runs through the inside of the plug plate 3, and the length of the scraper 2 is greater than the length of the mounting seat 1.

[0032] By setting the length of the scraper 2 to be greater than the length of the mounting base 1 and the outer side of the scraper 2 being smooth, the side wall of the scraper 2 can be closely attached to the wall when scraping the wall, so the corners of the wall can be scraped.

[0033] Reference Figure 2 , Figure 3 and Figure 4 , a spring 7 is arranged outside the support rod 5, and the diameter of the insertion rod 6 is larger than that of the support rod 5. A slot 11 is provided in the middle of the top surface of the mounting seat 1, and a limit block 14 is fixedly connected to the outer wall of the plug board 3, and the plug board 3 and the limit block 14 are both located inside the slot 11. A sliding hole 12 is provided on the front side of the middle of the mounting seat 1, and the support rod 5 is slidably connected inside the sliding hole 12. A limit groove 13 is provided on the rear side of the middle of the mounting seat 1, and the insertion rod 6 is located inside the limit groove 13. The sliding hole 12, the limit groove 13 and the slot 11 are interconnected, and a hole is provided in the middle of the plug board 3, and the insertion rod 6 is located in the hole.

[0034] When the scraper 2 needs to be replaced, the pull rod 4 is pulled, and the pull rod 4 can be used to drive the support rod 5 and the insertion rod 6 to move. At this time, the insertion rod 6 can be pulled out from the inside of the plug plate 3, and the spring 7 can be compressed. Then the scraper 2 can be pulled out to pull the plug plate 3 out of the inside of the mounting seat 1. At this time, the scraper 2 can be disassembled, and then the new scraper 2 is inserted into the inside of the mounting seat 1. Finally, the pull rod 4 is released. At this time, the support rod 5 and the insertion rod 6 can be pushed out by the elastic force of the spring 7. When the insertion rod 6 penetrates the plug plate 3, it will enter the inside of the limit groove 13. At this time, the plug plate 3 can be fixed, and then the replacement of the scraper 2 is completed.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A handle 8 is fixedly connected to the bottom surface of the mounting base 1. A plurality of weight-reducing holes 9 are provided in the middle of the scraper 2. A pulling hole 10 is provided in the middle of the pull rod 4. The handle 8 can facilitate the movement of the scraper 2, the weight-reducing holes 9 can reduce the weight of the scraper 2, and it is convenient for the staff to operate the scraper 2, and the pulling hole 10 can facilitate the pulling of the pull rod 4.

[0036] Working principle: When in use, the scraper 2 can be picked up by the handle 8, and the scraper 2 can be moved to scrape the wall. When the scraper 2 needs to be replaced, the pull rod 4 can be pulled to drive the support rod 5 and the insertion rod 6 to move. At this time, the insertion rod 6 can be pulled out from the inside of the insertion plate 3, and the spring 7 can be compressed. Then the scraper 2 can be pulled out to pull the insertion plate 3 out of the inside of the mounting seat 1. At this time, the scraper 2 can be disassembled, and then a new scraper 2 can be inserted into the mounting seat 1. , and finally release the pull rod 4. At this time, the support rod 5 and the insertion rod 6 can be pushed out by the elastic force of the spring 7. When the insertion rod 6 penetrates the insertion plate 3, it will enter the interior of the limiting groove 13. At this time, the insertion plate 3 can be fixed, and then the scraper 2 can be replaced. The length of the scraper 2 is set to be greater than the length of the mounting base 1. At the same time, the outer side of the scraper 2 is smooth. Therefore, when scraping the wall, the side wall of the scraper 2 can be made close to the wall, so the corner of the wall can be scraped.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
