The angle between the main vertical plate 41 and the auxiliary vertical plate 45 is 9 to 18 degrees. In S1 to FIG. 4, the indication angle between the main vertical plate 41 and the auxiliary vertical plate 45 is 90 degrees. 'In FIG. 5 to FIG. 7 , the angle between the main vertical plate 41 and the auxiliary vertical plate 45 is 1 degree degrees, and the detailed combination relationship will be described later in detail. Referring to FIG. 1 , FIG. 2 and FIG. 3 , The sector plate 42 and the connecting plate 46 pass through the mounting bolt 48 through the 201210774, pass through the mounting holes 4 [47, are fixed to each other' and the main vertical plate 41 and the auxiliary vertical plate 45 are perpendicular to each other for magnetic The corner of the monument is against. The wire hole 34 of the guide seat 33 of the plate unit 3 is opened with respect to the mounting bolt (10). When the movable type unit 4 is mounted on the plate unit 3, the mounting bolt 48 passes through the sector plate. The mounting hole 44 of the 42 and the mounting hole 47 of the connecting plate are screwed into the mounting hole of the guide 33, and the connecting plate 46 is mounted on the guide plate 42 and the guide of the backing unit 3. In addition, the positioning hole % on the guide block 33 of the plate unit 3 is opened relative to the positioning bolt 49, and the positioning bolt 49 is fixed in the positioning hole 35 through the arc-shaped guide groove 43 on the sector plate 42. To fix the angle of the main vertical plate 41 and the auxiliary vertical plate 45 with respect to the sawing unit 2. Referring to FIG. 2 and FIG. 4, when the vertical angle (4) is to be performed, the main vertical plate 41 is disposed along the axial direction of the core piece 21. The auxiliary vertical plate c is disposed in parallel with the guide seat 33, and the tile is placed. Abutting the main vertical plate 41 and the auxiliary vertical plate 45, and moving the magnetic tile toward the sawing unit 2, at this time, pushing the guide seat 33 to slide on the guide 32, the movable type can be driven The blade 21 is placed close to the tile by the single ^ 4 . When the cutting operation is performed at different angles, for example, the angle between the magnetic monument and the recording sheet shown in FIG. 4 is 45 degrees, the mounting screw 48 and the positioning bolt 49 are loosened, so that the sector plate 42 can be opposite to the guide. 33 pivoting, the curved guide groove 43 has a display angle scale table, the user can accurately adjust the planting angle of the sector plate a through the position of the pin = pin 49 relative to the scale table 'when it has been pivoted to After the predetermined angle, 'check the mounting thread 牦 201210774 累 position check 49 ' again to maintain the angle of the movable type against the unit 4.说 月 月 月 疋 疋 疋 疋 疋 疋 疋 疋 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月 月The obtuse corner of the brick is against. Referring to FIG. 5 and FIG. 6, the sliding platform 5 is disposed on the base 1 adjacent to the sawing unit 2 and the sliding platform 5 is parallel to the radial direction of the sheet (21). The shifting platform 5 includes a relative A mounting hole 51 is formed in the mounting bolt 48, and a positioning hole 52 is defined in the positioning bolt 49. Referring to FIG. 8, the sliding platform 5 is slidably mounted on the base cymbal, and the leveling σ 5 further includes a sliding rod 53 disposed at the bottom, and a recess 54 disposed at the side, the base 1 includes a pair of support seats U that should be recessed by the slide bar 53, and a pair of rollers 12 that are disposed on the concave guide rails 54, through which the slide platform 5 smoothly slides over the bases i, The combination of the slider 53 and the support base 11 provides support. Referring to FIG. 5 and FIG. 6 , when the movable abutment unit 4 is mounted to the sliding platform 5 by the flap unit 3, the top surface is opposite, that is, the sector plate 42 and the connecting plate 46 are turned upside down. And then mounted on the sliding platform 5. The movable abutting unit 4 further includes a second mounting hole 〇1 formed in the connecting plate 46 adjacent to the mounting hole 47, a protrusion 402 formed on the sector plate 42, and a recessed in the sector A groove 403 of the plate 42. When the movable abutment unit 4 is mounted on the sliding platform 5, the mounting bolts 48 sequentially pass through the second mounting hole 4〇1 of the connecting plate 46 and the mounting hole 44 of the sector plate 42 and are screwed thereto. In the mounting hole 51 of the sliding platform 5, the 201210774 connecting plate 46 is limited to the groove 403. At this time, the sector plate 42 is installed between the connecting plate 46 and the sliding platform 5, and the connecting plate is installed. The hole 47 is sleeved on the stud, and the mounting bolt 48, the post 4〇2 and the recess 403 are provided to provide sufficient structural strength of the movable abutment unit 4. It is worth mentioning that, in the foregoing installation manner, the main vertical plate 41 and the auxiliary vertical plate 45 are parallel to each other in parallel so as to abut the side edges of the magnetic monument, and if the main vertical plate 41 and the auxiliary vertical plate 45 are to be changed to each other, In the vertical configuration, the mounting bolt 48 is screwed to the mounting hole 47 of the connecting plate 46 and the mounting hole 44 of the sector plate. At this time, the protruding post 4〇2 is not mounted on the connecting plate 46. The hole 47 can change the movable abutment unit 4 to a vertical configuration. When the cutting operation is performed, the magnetic monument is abutted against the main vertical plate 41 and the auxiliary vertical plate 45, and the sliding platform 5 is brought close to the ore cutting unit 2 together with the movable abutting unit*. Referring to FIG. 6 and FIG. 7', when cutting operations at different angles are performed, the 45-degree angle 'the mounting bolt 48 and the positioning bolt 49 are loosened' as shown in FIG. 7 so that the sector plate 42 can be relatively slippery. The shifting platform 5 is pivoted, and the connecting plate 4 is also driven by the relationship between the protruding post 4〇2 on the sector plate 42 and the mounting hole 47 on the connecting plate 46. (5) pivoting relative to the sliding platform 5, and below the arc-shaped guiding groove 43, there is no angular scale on the sliding flat 5, and the user can use the clamping screw to complete the calibration. The position of the table 'accurately adjusts the insertion angle of the sector plate 42'. After pivoting to a predetermined angle, the mounting bolt 48 and the positioning bolt 49 are again checked to maintain the angle of the movable abutment unit 4. In summary, the movable abutment unit 4 is installed on the 201210774 board unit 3 or the migrating platform 5, and then the user adjusts the movable abutting unit according to the tile size or different cutting requirements. The installation position of 4, for example, when performing small-size cutting, the movable type can be The unit 4 is mounted on the sliding platform 5, closer to the cutting unit 2, to provide a more stable abutting effect, because the invention can achieve (4) an angle adjustable and suitable for different sizes of tile cutting operations, and The purpose of the present invention is to improve the convenience of use and the manner of use is more diverse.
