[0033] like Figures 1 to 3 As shown, a stair side plastering auxiliary device of the present invention is used to maintain uniform plastering thickness when plastering the side of the stairs. The plastering auxiliary device includes: a scraper bar 1, the top surface of the scraper bar 1 is in contact with the bottom surface of the stairs, and the scraper bar 1 is provided with an extension extending from the side of the stairs; scale lines 9 are provided on the top surface of the extension, the scale lines 9 are located at both ends of the extension and are parallel to the length direction of the extension, and the zero scale line of the scale lines 9 is aligned with the edge of the side of the stairs, and a fixing mechanism is provided on the scraper bar 1 for fixing the scraper bar 1 to the bottom surface of the stairs.

[0034] In a specific embodiment, the fixing mechanism is arranged on the side of the scraper bar 1, including: hinged rods 2 respectively hinged at both ends of the scraper bar 1; bolts 4 arranged on the corresponding hinged rods 2, the bolts 4 pass through the hinged rods 2 and are hooked on the horizontal plane of the stair tread; a gasket 3 that fits the horizontal plane of the stair tread, the gasket 3 is provided with an annular portion threadedly connected to the bolt 4, and the annular portion is tightened with the bolt 4 to clamp the hinged rod 2.

[0035] In a specific embodiment, there are multiple gaskets 3, and the thickness of the multiple gaskets 3 is inconsistent. When fixing the hinge rod 2, after the bolt 4 is inserted into the long hole 10, a gasket 3 of appropriate thickness is selected so that the gasket 3 supports the bolt 4. By tightening the bolt 4, the bolt 4 and the annular portion on the gasket 3 clamp the hinge rod 2 to prevent the bolt 4 from sliding up and down.

[0036] In a specific embodiment, the two hinged rods 2 are each provided with a long hole 10, and the bolt 4 passes through the long hole 10 and can be adjusted in position according to the thickness of the stairs.

[0040] In a specific embodiment, the cutter head assembly 8 includes: a slider slidably disposed in the through hole 7; a blade disposed on the top surface of the slider, the sharp portion of the blade being located outside the through hole 7; and a U-shaped rod disposed on the bottom surface of the slider for pulling the slider to move in the through hole 7.

[0041] The present invention also provides a method for using a stair side plastering auxiliary device, which specifically includes the following steps: fitting the top surface of the scraper bar 1 to the inclined surface of the stairs; adjusting the position of the scraper bar 1 so that the zero scale line of the scale line 9 is aligned with the edge of the side of the stairs; fixing the scraper bar 1 by a fixing mechanism; when plastering the side of the stairs, measuring the thickness of the plastering according to the scale line 9 on the scraper bar 1 so that the thickness of the plastering is consistent with the designed thickness; after the strength of the plastering reaches the designed strength, removing the device and installing it to the next construction location.

[0042] In a specific embodiment, the fixing mechanism includes two hinged rods 2, a bolt 4 provided on the hinged rods 2, and a gasket 3 threadedly connected to the bolt 4. The specific steps for fixing the scraper bar 1 through the fixing mechanism are as follows: rotate the two hinged rods 2 to keep the hinged rods 2 vertical; place the gasket 3 on the horizontal plane of the stair tread; pass the bolt 4 through the long hole 10 on the hinged rod 2, and turn the bolt 4 so that the bolt 4 is threadedly connected to the annular portion on the gasket 3.

[0043] The following is a detailed description of the use of the stair side plastering auxiliary device of the present invention.

[0044] The top surface of the scraper bar 1 is placed on the inclined surface of the stairs, and the reference line 6 is aligned with the edge of the inclined surface of the stairs.

[0045] Then, the bolt 4 is screwed to gradually rotate out of the bolt hole 5 .

[0046] Then rotate the hinge rod 2 to keep the hinge rod 2 vertical, and insert the bolt 4 into the long hole 10 on the hinge rod 2. Then select a gasket 3 of appropriate thickness, place the gasket 3 on the horizontal surface of the stair step, and continue to screw the bolt 4 so that the bolt 4 is threadedly connected with the annular portion on the gasket 3, so that the gasket 3 and the bolt 4 clamp the hinge rod 2, fix the position of the bolt 4, and thus fix the hinge rod 2.

[0047] Then provide a plastering tool to plaster the side of the stairs. When plastering, measure the thickness of the plastering according to the scale line 9 on the scraper bar 1 to make the thickness of the plastering consistent with the designed thickness.
