[0023] like Figure 1 As shown, the utility model provides a plastering tool, including a plastering knife 1 installed in a bracket, the bracket includes two support plates 19 arranged perpendicular to the length direction of the plastering knife 1, an electric telescopic rod 20 for adjusting the distance between the two support plates 19 and a passive telescopic telescopic plate 2 are provided between the two support plates 19, a slide groove is provided on the support plate 19 for the telescopic plate 2 to slide along the length direction of the support plate 19, and correspondingly, sliders matching the slide groove are provided at both ends of the telescopic plate 2. Adjustment grooves 3 are provided on the surfaces of both ends of the telescopic plate 2 in the length direction, an electric telescopic rod 6 is provided in the adjustment groove 3 in a direction perpendicular to the plane of the bracket, a protruding block 4 slidably provided in the adjustment groove 3 is provided on one side of the end of the electric telescopic rod 6, and the plastering knife 1 is provided at one end of the protruding block 4 protruding from the adjustment groove 3.

[0024] like Figure 2 As shown, the adjusting slots 3 are arranged in an array along the length direction of the telescopic plate 2. In a specific embodiment, the number of the adjusting slots 3 is 12, and the adjusting slots 3 of different gears can be selected according to the length of the plastering knife 1 to install the protruding blocks 4. The protruding blocks 4 installed at both ends of the telescopic plate 2 have different thicknesses, and the plastering knife 1 should be parallel to the length direction of the telescopic plate 2.

[0025] like Figure 3 , 4 As shown, in a specific embodiment, fixing blocks 7 are provided on both sides of the protruding block 4, and bolts 8 are provided on the fixing blocks 7. After the distance between the blade of the plastering knife 1 and the wall tiles is adjusted by the electric telescopic rod 6, the bolts 8 can be screwed into the fixing grooves 9 on both sides of the adjusting groove 3 to lock the protruding block 4.

[0026] like Figure 5 , 6 As shown, the end of the protruding block 4 extending into the adjustment slot 3 is a limit block 5, which is used to prevent the protruding block 4 from sliding out. The end of the protruding block 4 protruding from the adjustment slot 3 is connected to the plastering knife 1 through an angle adjustment mechanism, and the angle adjustment mechanism includes a movable block 10 fixed to one end of the protruding block 4, a rotating shaft 12 arranged on both sides of the plastering knife 1, and a gear 11 fixed on the rotating shaft 12. The movable block 10 is provided with gear teeth matching the gear 11, and the lower part of the gear teeth is provided with an axial hole matching the rotating shaft 12. The outer end of the rotating shaft 12 is provided with a handle 13, and the handle 13 is provided with a locking mechanism such as a card block, which can lock the rotating shaft 12 after determining the angle, so as to avoid the rotation of the plastering knife 1 when using it, resulting in an angle change. An embossed plate 14 is provided on one side of the plastering knife 1. The head end of the embossed plate 14 is provided with a plurality of embossed teeth, and the embossed plate 14 matches the length of the plastering knife 1.

[0027] like Figure 6 As shown, the back of the plastering knife 1 is connected to the handle 2 18 through a detachable connecting rod 17. A fixing plate 15 is provided at the bottom of the connecting rod 17, and a through hole is provided on the fixing plate 15. The through hole matches the threaded hole provided on the top surface of the plastering knife 1. The handle 2 18 can be fixed to the plastering knife 1 by screwing in the bolt 2 16, so as to facilitate the operation of the plastering knife 1.

[0028] The power supply circuit and control circuit of the electric telescopic rod 1 6 and the electric telescopic rod 2 20 described in the utility model can be arranged according to needs, such as being set on the upper surface of the bracket, or being connected to an external power supply and switch. The circuit is a conventional design and will not be described in detail.

[0029] The method of using the utility model is as follows: according to the size of the wall tiles to be laid, start the electric telescopic rod 20, so that the distance between the support plates 19 on both sides is significantly larger than the size of the wall tiles, place the wall tiles on the ground with their front side facing downward, then place the utility model on the wall tiles, then insert the protruding block 4 into the adjustment slot 3 of appropriate length, and then start the electric telescopic rod 6 to drive the protruding block 4 to move. After moving to an appropriate height, close the electric telescopic rod 6, then pass the bolt 8 through the threaded hole and rotate it into the fixing slot 9 to fix the fixing block 7, thereby fixing the protruding block 4.

[0030] Then, according to the length of the wall tiles, select a plastering knife of appropriate length and insert the rotating shafts 12 at both ends of the plastering knife into the shaft holes of the fixed block 7, and then further adjust the height of the electric telescopic rod 6 according to the thickness of the wall tiles and the thickness of the plastering, and then hold the handle 2 18, slide the plastering knife 1 along the support plate 19, so that the plastering knife 1 slides from one end of the wall tiles to the other end, and smoothes the mortar on the back of the wall tiles.

[0031] As needed, the handle 13 can be turned to adjust the angle adjustment mechanism to change the angle of the plastering knife 1 relative to the wall tiles. At the same time, the embossed plate 14 on one side of the plastering knife 1 can be tilted downward to control the depth of the grooves produced on the plaster surface. The embossed plate 14 can be used to draw multiple grooves for exhausting air on the smoothed mortar, thereby facilitating the laying of wall tiles.

[0032] After long-term use, if the plastering knife 1 is severely worn and needs to be replaced, the bolt 2 16 is turned to remove the bolt 2 16 from the fixing plate 15, so that the fixing plate 15 and the plastering knife 1 are separated, and a new plastering knife 1 can be replaced. This makes it convenient to reuse the other part by replacing the corresponding part when any part of the two is damaged, avoiding the waste of tools and materials caused by scrapping the plastering knife 1 as a whole.
