[0023] Specifically, the scraper 90 includes a slide bar 91 that is slidably connected to the inner wall of the rear side of the long groove 80. The front of the slide bar 91 is rotatably connected to the scraper bar 92. The front of the scraper bar 92 is provided with a pair of second circular holes 93 distributed up and down. The front of the slide bar 91 is provided with a third circular hole 94. The top surface of the slide bar 91 is threadedly connected to two studs 95. The outer wall of the stud 95 is provided with a fourth circular hole 96. A pair of second cavities are provided in the scraper 90. Both studs 95 extend into the second cavity. The bottom diameter of the stud 95 is larger than the upper diameter.

[0024] In this embodiment, water-based polyurethane mortar can be leveled, and the scraper 92 can be rotated. When the stud 95 is facing upward, preliminary leveling can be achieved. When the stud 95 is facing downward, the detachable defoaming mechanism 20 can be installed to achieve final leveling.

[0025] Specifically, a second fastening bolt 100 is threadedly connected to the lower front side of the long column 10, and the second fastening bolt 100 passes through the second circular hole 93 and is inserted into the third circular hole 94. Positioning grooves 200 matching the second fastening bolt 100 are provided in the middle of both sides of the scraper 92, and the positioning grooves 200 are semicircular structures.

[0026] In this embodiment, when the second fastening bolt 100 passes through the second circular hole 93 and is inserted into the third circular hole 94, the scraper strip 92 in the horizontal state can be locked. When the second fastening bolt 100 is inserted into the positioning groove 200, the scraper strip 92 in the vertical state (when stored) can be limitedly locked.

At this time, the scraper bar 92 is completely stored in the long groove 80. The entire water-based polyurethane mortar floor coating device is a relatively short round rod, which is small in size and very convenient to carry.

[0032] When the water-based polyurethane mortar is initially leveled, reverse the second fastening bolt 100 to separate it from the positioning groove 200, slide the slide bar 91 downward until it is no longer necessary, rotate the scraper bar 92 until it is in a horizontal state, and then rotate the second fastening bolt 100 forward so that the stud 95 is facing upward and the second fastening bolt 100 passes through the second circular hole 93 and is inserted into the third circular hole 94;

[0033] When the water-based polyurethane mortar is finally leveled, open the sealing cover 30 and take out the detachable defoaming mechanism 20 in the first cavity. At this time, make the stud 95 point downward (reverse the direction of the scraper 92), reverse the stud 95, and the stud 95 slowly protrudes until it can no longer rotate. The stud 95 stops protruding and the two fourth circular holes 96 are aligned. At this time, close the two elastically protruding slide rods 23, align the insertion shaft 25 with the fourth circular hole 96, loosen the slide rod 23, and under the elastic force of the spring 24, the insertion shaft 25 passes through the fourth circular hole 96, and the block 300 is attached to the outer wall of the stud 95.
