DETAILED DESCRIPTION

[0030] Please refer to Figures 1-6 The present application provides a technical scheme: a plastering device for preventing wall cracking, which has the same features as the prior art, including a ruler body 1 and a handle 13, two handles 13 are fixed on the upper and lower surfaces of the right side of the ruler body 1, the handle 13 can be held to operate the ruler body 1, and the two corners of the left side of the ruler body 1 for scraping the side edge are both set to be chamfered, which facilitates the use of chamfer to ensure that the plastering layer is scraped to a smooth state, in addition, the surfaces of both ends of the ruler body 1 are embedded with horizontal level tubes 14, and the surface of the ruler body 1 on the side of the horizontal level tube 14 is embedded with a vertical level tube 15 perpendicular to the horizontal level tube 14, which can also be used for testing the flatness and level of the wall plastering layer using the ruler body 1.

[0031] To meet the need for a rough plaster layer to meet different decoration requirements, the side surface of the ruler 1 is vertically provided with a groove 11, and a fixing plate 2 is also included. The size of the fixing plate 2 is slightly smaller than that of the groove 11. When in use, the fixing plate 2 is in contact with the surface of the groove 11. Through holes 23 are provided on the surface of the fixing plate 2 at both ends and the middle position. Screw holes 111 are provided in the groove 11 aligned with the through holes 23. The fixing plate 2 is locked by a locking bolt 22 that passes through the through holes 23 and screws into the screw holes 111. At this time, the exposed part on the side of the fixing plate 2 is evenly fixed with outwardly protruding bristles 21. Therefore, when the plaster layer is smoothed, the bristles 21 can work with the plaster layer to create a rough surface. When it is not necessary to create a rough surface for smoothing, the locking bolt 22 can be unscrewed to remove the fixing plate 2 and the bristles 21.

[0032] With the above structural arrangement, since the plate groove 11 and screw hole 111 exist, when the fixing plate 2 and brush 21 are not used, mortar is easy to stick into the plate groove 11 or screw hole 111 and cause pollution. Therefore, a rubber sheet 3 with a thickness less than the fixing plate 2 is also provided. The rubber sheet 3 can be placed inside the plate groove 11 to separate and protect the plate groove 11 and screw hole 111 and prevent mortar from entering.

[0033] Additionally, the body 1 has a storage slot 12 inside, and a cover 4 is attached to the top of the storage slot 12 to seal it. A rubber insert 41 is provided below the cover 4 and is inserted into the upper part of the storage slot 12 to fix the cover 4. When in use, the idle rubber sheet 3 or fixing plate 2 and brush bristle 21 structure can be placed in the storage slot 12 and the cover 4 can be closed, thus facilitating the storage and carrying of the rubber sheet 3 or fixing plate 2.

[0034] A groove is also provided on the surface of the rubber insert 41, and a magnet 411 is embedded and fixed in the groove. After the fixing plate 2 is removed, the locking bolt 22 can be placed in the groove and then attracted by the magnet 411, making it convenient to store.

[0035] In use, when the trowel layer is scraped flat, the locking pin 22 is unscrewed to remove the fixed plate 2 and the brush 21 structure, then the plug 4 is pulled upwards, the fixed plate 2 and the brush 21 are put into the storage groove 12 for storage, and the locking pin 22 is placed in the groove of the rubber plug 41 and is adsorbed and fixed by the magnet block 411, then the rubber sheet 3 stored in the storage groove 12 is taken out and is inserted into the plate groove 11 to be hidden to avoid entering the mortar, then the rubber plug 41 is inserted into the inside of the storage groove 12 above to block the storage groove 12 by the plug 4, the handle 13 is held to hold and operate the ruler body 1 to scrape the trowel layer, if the trowel layer surface needs rough lines, then the plug 4 is taken down again, the rubber sheet 3 is taken down and put into the storage groove 12 for storage, the stored fixed plate 2 and the brush 21 structure are taken out, and the locking pin 22 adsorbed by the magnet block 411 in the groove of the rubber plug 41 is taken out, the plug is covered, the fixed plate 2 is again attached to the plate groove 11, the locking pin 22 is screwed into the screw hole 111 through the through hole 23 penetrating the fixed plate 2, the fixed plate 2 is locked to the plate groove 11 again, the brush 21 is leaked to the side edge of the ruler body 1, and the brush 21 can be scraped on the trowel layer surface when the ruler body 1 is used again to scrape the trowel layer, so that a rough surface is formed to meet the subsequent decoration requirements.
