[0022] like Figure 1-7 As shown, the guide rail 1 of the present invention is arranged longitudinally, and a locking groove 21 with an inward opening is provided on the inner side of the guide rail 1. A row of locking bolts 22 are threadedly connected to the top of the locking groove 21. During installation, the locking groove 21 is clamped on the side edge of the cutting platform and then locked by the locking bolts 22.

[0023] A sliding seat 4 is slidably installed on the guide rail 1, and a rotating shaft 7 is installed on the top of the sliding seat 4. A track groove 5 is provided at the outer end of the guide rail 1, and the upper and lower side walls of the track groove 5 are relatively set in a V shape. The inner end of the sliding seat 4 is connected to an upper and lower row of rollers 6, and the upper row of rollers 6 are rollingly supported in the V-shaped groove above the track groove 5, and the lower row of rollers 6 are rollingly supported in the V-shaped groove below the track groove 5.

[0024] The rollers 6 in the upper row are rotatably mounted on the sliding seat 4 via a coaxially arranged first rotating shaft 26. The rollers in the lower row are coaxially mounted with a second rotating shaft 27. A height adjustment nut 25 is coaxially fixed on the second rotating shaft 27. A screw is eccentrically arranged on the height adjustment nut 24. The screw 23 is threadedly connected to the sliding seat 4. The outer end of the screw 23 extends out of the sliding seat 4 and is threadedly connected to the fixing nut 24. When assembling the rollers 6, the upper row of rollers 6 is used as a reference, and the fixing nut 24 corresponding to the lower row of rollers 6 is loosened. The height adjustment nut 25 can be rotated to adjust the upper and lower positions of the corresponding rollers 6 to ensure that the upper and lower rows of rollers 6 respectively roll and fit on the upper and lower side walls of the track groove 5.

[0025] A square cross bar 2 in a T-shaped structure is slidably mounted on the guide rail 1. The end of the square cross bar 2 is connected to a rotating seat 8. The rotating seat 8 is rotatably connected to the rotating shaft 7 on the top of the sliding seat 4 through a bearing. The tail end of the rotating seat 8 is provided with a protrusion 9 protruding backward relative to the rotation center. The protrusion 9 is used to contact the outer wall of the sliding seat 4 to form a limit when the square cross bar 2 is rotated upward to an angle greater than 90° (specifically 95°-130°) with the horizontal plane.

[0026] A cutting wheel assembly 3 is mounted on the square cross bar 2. The cutting wheel assembly 3 includes a tool holder 10 that is slidably mounted on the square cross bar 2. A pressing bolt 11 that presses against the square cross bar 2 is threadedly connected to the tool holder 10. Loosening the pressing bolt 11 can adjust the cutting position of the cutting wheel assembly 3.

[0027] A scale 19 is provided on the upper surface of the square crossbar 2 , and a scale indicator 20 aligned with the scale is connected to the tool holder 10 .

[0028] The side of the tool holder 10 is provided with a knife pressing block 12 with one end rotatably connected, and the other end of the knife pressing block 12 is connected to the tool holder 10 through a handle bolt 13. A guide rod 14 is clamped between the knife pressing block 12 and the tool holder 10, and a protrusion 15 is provided in the middle of the inner side surface of the knife pressing block 12. A clamping groove that matches the cross-section of the guide rod 14 is provided between the protrusion 15 and the tool holder 10, and the inner side surface of the guide rod 14 is set to a plane 16 that fits the clamping groove. When locked, the protrusion 15 forms a locking fulcrum, which can lock the guide rod more firmly on the tool holder 10.

[0029] The guide rod 14 is arranged obliquely and extends downward to the bottom of the tool holder 10. The lower end of the guide rod 14 is rotatably installed with a cutting wheel 17 located in the middle of the width direction of the square cross bar 2. The setting position of the cutting wheel 17 is in the same direction as the force applied to the tool holder 10 during cutting, which saves more effort when used.

[0030] A leveling bubble 28 is provided on the tool holder 10. The leveling bubble 28 is provided to ensure that the cutting wheel 17 is in a vertical state with the tile being cut.

[0031] A limiting wheel 18 is rotatably installed on the side of the cutting wheel 17 away from the cutting direction. The supporting surface of the limiting wheel 18 is higher than the bottom end of the cutting wheel 17, and the distance a between them is less than the thickness of the tile being cut. When the cutting wheel 17 cuts to the end of the tile and leaves the tile surface, it is supported downward on the tile by the limiting wheel 18 to prevent the cutting wheel from damaging the cutting platform.

[0032] When the utility model is used, the cutting wheel 17 of the cutting wheel assembly 3 is driven by the square cross bar 2 to cut the tiles. After the cutting is completed, the square cross bar 2 can be rotated upward to a state greater than 90 degrees from the horizontal plane, which is convenient for replacing tiles.
