The semi-automatic shaft sleeve device of the galvanometer motor according to claim 6, characterized in that: The invention also includes a stable guide structure, which includes a guide rail fixing plate (24), a motor fixing plate (25), a guide rail (26), a slider (27) and a sleeve shaft sliding plate (63), wherein the guide rail fixing plate (24) is vertically fixed on the semi-automatic sleeve shaft bottom plate (21), one end of the motor fixing plate (25) is horizontally fixed on the top of the stepping motor (61), and the other end is vertically fixed on the guide rail fixing plate (24), the linear guide rail (26) is vertically fixed on one side of the motor fixing plate (25) on the guide rail fixing plate (24) above the motor fixing plate (25), the slider (27) is installed on the guide rail (26) and slides vertically on the guide rail (26), and one end of the sleeve shaft mechanism fixing plate (67) far from the sleeve shaft mechanism (1) is fixed on the slider (27) through the sleeve shaft sliding plate (63).

10. The semi-automatic shaft sleeve device of the galvanometer motor according to claim 9, characterized in that: A photoelectric switch (64) is also mounted on the guide rail fixing plate (24), and a photoelectric switch baffle (65) is mounted on the sleeve shaft sliding plate (63). The photoelectric switch baffle (65) is provided with a bend that is folded toward the guide rail fixing plate (24). When the sleeve shaft mechanism (1) rises to a height position where the photoelectric switch (64) is mounted, the bend extends between the U-shaped light-emitting portion and the light-receiving portion of the photoelectric switch (64).
