[0029] Working principle: The metal door or window to be cut is placed tightly against the front surface of the long plate 10. The portion to be cut is then pushed above the groove 9. The bolt 13 is rotated, and the pressure plate 15 presses down on the pressure plate 14. At this point, the lower surface of the pressure plate 14 is in close contact with the upper surface of the metal door or window. As the bolt 13 feeds downwards, the pressure plate 14's restraining effect on the metal door or window increases. When an inclined cut is required, the inclination angle is first determined according to the needs. Then, the restraint of the fixing member 12 on the long plate 10 is addressed, and the angle of the long plate 10 can be rotated to change it. During the rotation of the long plate 10, the magnetic piece 19 on the upper surface of the top block 17 in the fixing member 12 contacts the iron right-angle plate 6, thus using magnetic attraction to provide a suspension force for the fixing member 12, preventing the fixing member 12 from affecting the smooth rotation of the long plate 10. After the angle is changed, the fixing member 12 is reset, improving the stability of the long plate 10 during operation. Finally, the metal door or window is placed tightly against the long plate 10. The front surface can then be cut again for metal doors and windows. In the actual use of this device, a protractor can be placed on the upper surface of the iron right-angle plate 6, and marking lines can be pasted on the long plate 10 at the corresponding positions of the protractor, thereby further assisting workers in controlling the tilt angle. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
