The concrete working principle and the beneficial effects of the embodiment are as follows:

the working principle is as follows:

when splicing the ceramic tiles, an operator firstly pastes two adjacent ceramic tiles along one side line and lays the ceramic tiles on the ground, then the pad 11 is pressed between the ground and the ceramic tile, the other two ceramic tiles are respectively jointed along the side lines of the two ceramic tiles laid firstly, the driver 6 is then rotated by means of the first lever 161, so that the projections 21 are aligned with the catches 61, then, by means of the first support rod 161, the driving member 6 is moved toward the side close to the bottom surface of the tile, the outer wall of the projection 21 presses the wedge-shaped guide surface of the wedge-shaped block 41, the wedge-shaped block 41 presses the spring to move toward the bottom of the groove 31, when the notch of the groove 31 is aligned with the notch of the catching groove 32, the wedge block 41 moves away from the bottom of the groove 31 under the spring force, and then realize the joint cooperation between wedge 41 and the joint groove 32, realize that the joint between driving piece 6 and the pressfitting piece 2 is fixed.

At this moment, the operator can rotate the driving element 6 along the clockwise or counterclockwise direction by means of the first supporting rod 161, the pressing element 2 moves towards one end close to the bottom surface of the tile along the axial direction of the base 1, the clamping block 17 ascends along the length direction of the clamping strip 25 relative to the clamping strip 25, and then the pressing element 2 applies vertical downward pressure to the tile, so that the pressing element 2 compresses the tile.

Has the advantages that:

realize the joint between driving piece 6 and the pressfitting piece 2 through the joint between wedge 41 and joint groove 32 fixed, operating personnel is through rotating driving piece 6, and driving piece 6 drives the axial rotation of pressfitting piece 2 around base 1 and towards being close to the motion of ceramic tile bottom surface one end, realizes the pressfitting piece 2 to compressing tightly of ceramic tile, and then realizes the adjustment of ceramic tile roughness, has guaranteed that the surface of ceramic tile is level and smooth.

Because driving piece 6 is when rotating, drive the fixed pressfitting piece 2 of joint with it and move towards the direction that is close to the ceramic tile bottom surface along base 1's axial, through the slip joint between fixture block 17 and the card strip 25, and then realize compressing tightly the in-process of ceramic tile at pressfitting piece 2, fixture block 17 moves towards keeping away from ceramic tile bottom surface one side along card strip 25, and then realizes pressfitting piece 2 to the leveling of ceramic tile, has reduced the condition that can't normally carry out the ceramic tile leveling because of lacking the pliers.

Because the pressfitting piece 2 exerts vertical decurrent pressure to the ceramic tile, just can flatten the ceramic tile of laying unevenness, because at the in-process of rotating driving piece 6, driving piece 6 drives pressfitting piece 2 towards the axial of base 1 and is close to the motion of ceramic tile bottom surface one end, so through set up on first latch 26 towards decurrent inclined plane 28, inclined plane 28 has a effect of direction on the one hand, is convenient for the relative motion between fixture block 17 and the gib 25.

The inclined surface 28 is arranged downwards, so that the clamping block 17 can move from bottom to top along the clamping strip 25 and cannot move from top to bottom, and the stability of the pressing piece 2 for pressing the ceramic tile is enhanced; the stability of the locking block 17 on the locking strip 25 is also enhanced by the engagement between the second locking teeth 27 and the first locking teeth 26, thereby ensuring the stability of the pressing piece 2 in the tile leveling.

Because in the process of rotating the driving part 6, the driving part 6 drives the pressing part 2 fixed in clamping connection with the driving part to rotate around the axial direction of the base 1, and under the meshing connection effect of the first clamping tooth 26 and the second clamping tooth 27, the fixture block 17 moves towards one end far away from the tile bottom plate along the fixture strip 25, and through the arrangement of the retaining edge 22, the retaining edge 22 plays a limiting role on the fixture block 17, so that the separation of the fixture block 17 from the inner wall of the pressing part 2 is reduced, namely the separation possibility of the base 1 from the pressing part 2 is reduced.

When the driving piece 6 moves towards the side close to the bottom surface of the tile along the axial direction of the base 1, the wedge-shaped block 41 is provided with a wedge-shaped guide surface, the outer wall of the pressing piece 2 presses the wedge-shaped guide surface of the wedge-shaped block 41, the wedge-shaped block 41 presses the elastic piece 42 to move towards the direction close to the bottom of the groove 31, when the notch of the groove 31 is aligned with the notch of the clamping groove 32, the wedge block 41 moves away from the bottom of the groove 31 under the elastic force of the elastic piece 42, and clamping between the wedge block 41 and the clamping groove 32 is realized, so as to realize the relative clamping fixation between the driving piece 6 and the pressing piece 2, and further an operator can rotate the driving piece 6 by means of the driving piece 6, thereby realizing that the driving piece 6 drives the pressing piece 2 to rotate around the axial direction of the base 1, realizing the pressing of the pressing piece 2 to the ceramic tile, and then the gaps of the ceramic tiles are reduced, the adjustment of the flatness between the adjacent ceramic tiles is realized, and the tidiness and the attractiveness of the ceramic tiles in laying are ensured.

Because at the in-process of rotating driving piece 6, driving piece 6 drives the fixed pressfitting piece 2 of joint with it and moves towards the direction of being close to one side of the ceramic tile bottom plate around the axial of base 1, and at the in-process that pressfitting piece 2 compressed tightly the ceramic tile, through the setting of arc portion 23, change the contact between the face between pressfitting piece 2 and the ceramic tile into the contact of line and face between pressfitting piece 2 and the ceramic tile, and then reduced area of contact, be convenient for the rotation of pressfitting piece 2, simultaneously, because arc portion 23 is made by elastic material, so the plasticity of arc portion 23 is good, consequently, reduced pressfitting piece 2 and the ceramic tile contact in the rotation process and scraped the possibility on colored ceramic tile surface.

The alignment between the bump 21 and the engaging portion 61 is further facilitated by the provision of the arc angle 24.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
