The support plate 61 is a rectangular plate and is fixedly connected to the outside of the end corner position of the fixed frame 1. A sliding long hole 611 is provided on the support plate 61. The length direction of the sliding long hole 611 is consistent with the diagonal length direction of the fixed frame 1 at the end corner position. One end of the sliding long hole 611 is connected to the outer wall position of the fixed frame 1; the top of the positioning block 62 is slidably connected to the sliding long hole 611 and can slide along the length direction of the sliding long hole 611. The side of the positioning block 62 close to the fixed frame 1 is provided with an abutment groove 621. The abutment groove 621 is a 90-degree open groove structure and is located below the fixed frame 1; when the fixed frame 1 is placed on the floor tile 7, the positioning block 62 slides along the sliding long hole 611 toward the end corner direction of the fixed frame 1 and makes the inner wall of the abutment groove 621 contact with the outer wall of the end corner position of the floor tile 7, so as to achieve the position limiting effect of the positioning assembly 6 on the floor tile 7.

[0041] The locking mechanism includes a tension spring 64 and a locking block 63; the top of the positioning block 62 is integrally formed with a locking protrusion 622, which is in the shape of a rectangular column. The width of the locking protrusion 622 is adapted to the width of the sliding long hole 611 and the two are slidably connected, and the locking protrusion 622 will not rotate during the sliding process in the sliding long hole 611; the top of the locking protrusion 622 passes through the sliding long hole 611 and extends into the sliding groove 632 at the bottom end of the middle of the locking block 63, and the top of the locking protrusion 622 can slide longitudinally in the sliding groove 632; the bottom end of the locking block 63 is provided with a first inclined surface protrusion 631, and the upper end surface of the support plate 61 is provided with a plurality of second inclined surface protrusions 612 along the length direction of the sliding long hole 611, the top of the second inclined surface protrusion 612 is an inclined surface structure and the inclined structure is close to the fixed The height of one end of the fixed frame 1 is higher than the height of the end away from the fixed frame 1; the bottom end of the first inclined protrusion 631 is an inclined structure and the inclination direction of the inclined structure is consistent with the inclination direction of the top end of the second inclined protrusion 612; a tension spring 64 is arranged between the clamping protrusion 633 and the clamping block 63. When the tension spring 64 is in a normal state, the tension spring 64 causes the clamping block 63 to generate a force close to the support plate 61, and the first inclined protrusion 631 at the bottom end of the clamping block 63 is clamped in the gap between the two adjacent second inclined protrusions 612; under the clamping action of the first inclined protrusion 631 and the second inclined protrusion 612, the positioning block 62 and the clamping block 63 can move unidirectionally along the sliding long hole 611 toward the fixed frame 1, and cannot move in the direction away from the fixed frame 1.

[0042] After the fixed frame is placed on the floor tile, the first limiting protrusion and the second limiting protrusion limit the rear and right sides of the floor tile so that the fixed frame and the floor tile are kept flush; then, the positioning block is moved toward the fixed frame until the abutting groove on the positioning block contacts the left and front corners of the floor tile. At this time, the floor tile is confined between the first limiting protrusion, the second limiting protrusion, and the positioning block. When filling the filling area with cement mortar, the fixed frame and the floor tile will not move relative to each other, thereby improving the plastering speed and plastering effect of the floor tile;

[0043] After applying the cement mortar, just pull up the locking block to separate the first inclined protrusion from the second inclined protrusion, and then the locking block and the positioning block can be moved away from the fixed frame, thereby releasing the restriction of the positioning block on the floor tiles. At this time, the fixed frame can be removed from the floor tiles to complete the plastering operation of the floor tiles.

[0047] Hold the handles with both hands and place the fixed frame on the floor tiles. Move the first and second limiting protrusions to limit the rear and right sides of the floor tiles. Then, release the handles. The handles rotate downward together with the movable rod under the action of the torsion spring and the side walls of the arc-shaped curved portion of the handles abut against the left and right outer walls of the floor tiles (such as Figure 6 As shown in the figure, it realizes the limiting operation on the left and right sides of the floor tiles, further improving the stability of the connection structure between the fixed frame and the floor tiles, and avoiding the relative deviation between the fixed frame and the floor tiles when applying cement mortar, which affects the application effect of cement mortar.

[0048] After applying the cement mortar and moving the positioning block and the locating block away, hold the handle with both hands and move it upwards to make the arc curved part leave the outer wall of the floor tile, and then continue to pull the handle to move the fixed frame upwards in a horizontal state (such as Figure 7 As shown), eventually leaving the floor tiles;

[0049] During the lifting process, both hands hold the handle bar on the handle piece. Due to the design of the arc curved part, when one side of the arc curved part contacts the floor tiles, the other side of the arc curved part supports the handle bar to a certain height, so that there is a certain gap between the handle bar and the ground, which is convenient for people to hold the handle bar.

After applying, the cement mortar is smoothed so that the cement mortar is flush with the top end surface of the fixed frame. Finally, the fixed frame is moved upward by holding the handpiece, leaving the floor tile, and the application of cement mortar on the back of the floor tile is completed. The floor tile can be turned over and laid on the ground; this operation can ensure the uniformity of the plastering thickness of the floor tile and the flatness of the plastering surface, which changes the inaccuracy of traditional manual control of the plastering thickness, and can realize uniform control of the cement mortar thickness on the floor tile, while facilitating construction and improving the quality of the floor tile plastering operation, avoiding the quality risks of incomplete laying of floor tiles and hollowing of floor tiles, effectively improving the construction efficiency and laying quality of floor tiles, and bringing convenience to the construction operation of floor tiles.
