Numerically-controlled tool rest for machining of numerically-controlled machine tool

The numerical control tool rest comprises a tool apron, a mounting base, a mounting block, a tool turret, a screw rod and a baffle, a threaded groove is formed in the mounting block, a movable shaft is arranged on the side face of the mounting base, a connecting rod is fixedly connected to one side of a rotating handle, and the connecting rod is fixedly connected to the other side of the rotating handle. A vertical gear and a transverse gear are arranged in the mounting seat, one side of the vertical gear is fixedly connected with one side of the connecting rod, the bottom of the transverse gear is movably connected with the bottom of the inner wall of the mounting seat, a threaded rod is fixedly connected to the top of the transverse gear, and the surface of the threaded rod is rotationally connected with the inner wall of the mounting block; when the height of the cutter needs to be adjusted, a rotating handle and a screw rod are rotated, the rotating handle drives a connecting rod and a vertical gear to ro
