Double-galvanometer square head

The embodiment of the utility model discloses a double-galvanometer square head. Comprising a laser emitting assembly, a first galvanometer assembly, a second galvanometer assembly, a field lens mechanism and a base, the first galvanometer assembly and the second galvanometer assembly are symmetrically arranged about the center line of the base in the vertical direction, and the laser emitting assembly emits a first laser beam and a second laser beam; the first laser beam is reflected by the first galvanometer assembly and refracted by the field lens mechanism to be focused on the working face to form a light path A, the second laser beam is reflected by the second galvanometer assembly and refracted by the field lens mechanism to be focused on the working face to form a light path B, and the incident section of the light path A and the incident section of the light path B are located on the same horizontal plane. The first galvanometer assembly and the second galvanometer assembly are integrated into the sam
