Machining device with fixing function for door and window machining

The door and window machining device with the fixing function comprises a base, a fixing mechanism, a first sliding block, a first lead screw and a third lead screw, the first lead screw is connected with an output shaft through a first belt, and a second lead screw is connected with the output shaft through a second belt. A third bearing seat is installed on the left side of the cavity, and a machined part is installed above the fixing mechanism. The door and window machining device with the fixing function is provided with two fixing mechanisms, a base, a threaded rod, a rotary knob, a fixing block, a rotating shaft and a fixing seat, the threaded rod is driven to move rightwards by rotating the rotary knob, then the fixing block is pushed to rotate under the action of the rotating shaft, and when the upper end of the fixing block abuts against the side face of a workpiece, the workpiece can be fixed. And meanwhile, the two ends of the workpiece can be fixed through the design of the two fixing mechanisms,
