[0015] Please see Figure 1-3This utility model provides a technical solution: It includes a table saw panel 1, with a mounting groove 11 at its center. A saw blade 12 is installed in the mounting groove 11. A drive device for rotating the saw blade 12 is fixed to the bottom of the table saw panel 1. The upper end of the saw blade 12 extends out of the table saw panel 1. Limiting plates 2 and limiting sleeves 3 are respectively installed on the table saw panel 1 on both sides of the mounting groove 11. A sliding groove 4 is provided on the upper end of the table saw panel 1 at a position corresponding to the limiting plates 2. A sliding plate 41 is slidably connected within the sliding groove 4. A threaded rod 42 is rotatably connected to the inner part of the table saw panel 1. The threaded rod 42 passes through the sliding plate 41 and is threadedly connected to the sliding plate 41. One end of the threaded rod 42 extends out of the table saw panel 1 and is fixed with a rocker arm 43. A pair of guide rods 44 are fixed in the sliding groove 4. The guide rods 44 pass through the sliding plate 41 and are slidably connected to the sliding plate 41. The center position of the limiting plate 2 is rotatably connected to the sliding plate 41. Fixed components are provided between the two ends of the limiting plate 2 and the table saw panel 1. Adjustment components are provided on the table saw panel 1 at the corresponding positions of the limiting sleeve 3.

[0016] The fixing component includes a straight groove 5 and a locking nut 53. The straight groove 5 is opened on the upper end of the table saw panel 1 and is aligned with both ends of the limiting plate 2. A straight slider 51 is slidably connected in the straight groove 5. A bolt 52 is fixed on the upper end of the straight slider 51. The upper end of the bolt 52 passes through the limiting plate 2 and is threadedly connected to the locking nut 53. An anti-slip pad is fixed on the upper end of the limiting plate 2. A movable groove 21 is opened on the limiting plate 2 at the position corresponding to the bolt 52. A scale plate 22 is fixed on the lower outer side of the rear side of the limiting plate 2. A deflection angle scale line is provided on the scale plate 22.

[0017] The adjustment assembly includes an adjustment groove 31, which is located on the upper end of the table saw panel 1 and aligned with the limiting sleeve 3. A mounting block is slidably connected inside the adjustment groove 31. The limiting sleeve 3 is rotatably connected to the upper end of the mounting platform. A lead screw 32 is rotatably connected inside the adjustment groove 31. The lead screw 32 passes through the mounting block and is threadedly connected to the mounting block. The lead screw 32 extends out of the table saw panel 1 and is fixed with a rotating plate 33.

[0018] Working Principle: First, the entire device is connected to an external power source. The drive unit rotates the saw blade 12 at high speed. When the saw blade 12 is used to horizontally push the door and window production material, cutting is achieved. During this process, the limiting plate 2 can be slid horizontally according to the required cutting width, changing the distance between the limiting plate 2 and the saw blade 12. Therefore, when the side of the material slides against the limiting plate 2, cutting of different widths can be achieved, improving cutting accuracy. Secondly, when different angles of cutting are required, the limiting plate 2 can be rotated to tilt at a suitable angle, thus moving along the limiting plate 12. When the positioning plate 2 pushes the plate, it can tilt the cutting blade at a specified angle, increasing overall practicality and improving cutting accuracy. During this process, the locking nut 53 is rotated to lock the two ends of the limiting plate 2, ensuring stability during the limiting process. Secondly, the movable groove 21 is opened to ensure that the limiting plate 2 can deflect at a certain angle. At the same time, during the processing, the position of the limiting sleeve 3 is moved so that it abuts against the other side of the plate, which can reduce the risk of the plate shifting outward. During this process, the rotation of the rotating plate 33 can drive the lead screw 32 to rotate, thereby driving the mounting block and the limiting sleeve 3 to slide horizontally.
