[0002] Gypsum self-leveling, also known as self-leveling floor leveling plaster, gypsum-based self-leveling mortar or gypsum self-leveling, is a lightweight lime paste specially used for indoor floor leveling. It is made of high-strength gypsum, aggregate and various construction chemical additives that are carefully configured and mixed evenly in the factory. During the construction process of gypsum self-leveling, bubbles may appear on the surface. The gypsum self-leveling defoaming roller rolls on the construction surface to help expel bubbles from the gypsum material to obtain a flat and bubble-free surface. The use of the gypsum self-leveling defoaming roller can improve construction efficiency and reduce or eliminate the need for subsequent sanding.

By providing the positioning seats 10, the driven rods 7 can be positioned to prevent skewing.

[0023] like Figure 4 As shown, the outer surfaces of the two driven rods 7 are fixedly connected with limiting rings 12, and the outer surfaces of the two driven rods 7 are sleeved with contraction springs 13. One end of the two contraction springs 13 is fixedly connected to one side of the two positioning seats 10 respectively, and the other ends of the two contraction springs 13 are in contact with one side of the two limiting rings 12 respectively. By setting the limiting rings 12, the movable range of the driven rod 7 can be limited, and a force point can be provided for the contraction spring 13, so that the driven rod 7 can be automatically reset.

[0024] like Figure 2 and Figure 3As shown, the outer surfaces of the two positioning rods 3 are both sleeved with reset springs 4, and one side of the trapezoidal block 5 is fixedly connected to a pull rod 6, one end of the pull rod 6 passes through a side wall inside the adjustment box 2.
