Angle adjustable cutting device for plastic-steel door and window machining

The invention discloses an angle adjustable cutting device for plastic-steel door and window machining. The angle adjustable cutting device for plastic-steel door and window machining comprises a base. The sides, close to each other, of vertical extending plates at the left end and the right end of the base are both provided with T-shaped sliding rails. The front end and the rear end of the top ofthe base are connected with fixed ends of two parallel first electric extensible and retractable rods correspondingly. The extensible and retractable ends of the two first electric extensible and retractable rods are connected with the front end and the rear end of the bottom of a fixing chamber correspondingly. The left side and the right side of the fixing chamber are provided with T-shaped sliding strips which are vertically distributed. The two T-shaped sliding strips are in sliding connection with the two T-shaped sliding rails correspondingly. According to the angle adjusting cutting device, the situation that a plastic-steel door and window deviates during machining, and the cutting angle is changed can be prevented, meanwhile, a pointer rotates, the rotation angle can be determined, angle contrasting can be carried out, defective materials can be prevented from dropping out and are cleaned conveniently, the stability of the device is improved, buffering is carried out, a cutting piece can be prevented from excessively cutting into the plastic-steel door and window, and then the situation the cutting device is fractured and clamped on the plastic-steel door and window is prevented.
