[0024] In this method, a placement mechanism 3 is provided on the profile cutting table 1, and the placement mechanism 3 includes an electric telescopic rod 31, which is fixedly installed on the upper side of the profile cutting table 1 and a placement groove 32 is fixedly installed on the upper end of the electric telescopic rod 31. A slide 33 is symmetrically and slidingly installed on the inner side of the placement groove 32, and a driving threaded rod 34 is rotatably installed on the outer side of the slide 33. The driving threaded rod 34 is screwed through the outer side of the placement groove 32, and the inner side of the slide 33 clamps the door and window profile 4.

[0025] Through the above-mentioned arrangement, the inner slide 33 can be driven to slide inside the placement groove 32 by rotating the driving threaded rod 34, so that the slide 33 can clamp the door and window profiles 4 of different widths placed inside the placement groove 32, thereby improving the applicability of the entire placement mechanism 3 and enhancing the practicality of the present invention.

[0026] In this embodiment, the slide plate 33 is symmetrically fixedly connected with a slide rod 35 , and the slide rod 35 slides through to the outside of the placement groove 32 .

[0027] By setting the slide plate 33 in the above manner, when the slide plate 33 slides in the placement groove 32, it can be synchronously guided by the sliding rod 35, thereby improving the stability of the slide plate 33 during adjustment, and further strengthening the stability of the slide plate 33 when clamping the door and window profile 4.

The corresponding vertical cutting inclination angle is adjusted. The limiting screw 512 is loosened, and the adjustment telescopic rod 510 is driven to adjust to the corresponding inclination scale line 511. The limiting screw 512 is tightened to limit the telescopic freedom of the adjustment telescopic rod 510. At this point, the cutting angle adjustment is completed, and the cutting work is subsequently carried out. When cutting, the electric telescopic rod 31 is started, and the door and window profile 4 clamped in the inner side of the placement groove 32 is moved upward close to the cutting saw blade 7 for cutting.
