Angle-adjustable cutting machine

The invention discloses an angle-adjustable cutting machine, relates to the technical field of cutting machines, and aims to solve the problems that the cutting angle cannot be changed, the notch quality is poor and the precision is low in the prior art, the angle-adjustable cutting machine comprises a workbench, supporting plates are fixed to the two sides of the top of the workbench, and fixing frames are fixed to the tops of the two supporting plates; threaded rods are rotationally connected to the inner walls of the two ends of the fixing frame, sliding blocks are connected to the threaded rods in a threaded mode, first push rod motors are fixed to the bottoms of the sliding blocks, and cutting mechanisms are fixed to the bottoms of the first push rod motors. A second servo motor drives a mounting block to deflect so as to adjust the inclination angle of the mounting block, so that a second push rod motor and a cutting assembly below the second push rod motor incline correspondingly, then the cutting angl
