[0002] With the development of industrial technology, modern scanning instrument technology is becoming more and more perfect. The laser scanning galvanometer also needs to be equipped with a servo motor to drive the lens to move and position. In the past, the galvanometer motor could only control one lens. If there are multiple lenses in the device, multiple servo motors are needed to control it, which requires more space inside the device to accommodate the servo motor protection.

[0003] Secondly, the optical scanning instrument's lighting device requires a variable laser scanning galvanometer. The previous laser scanning galvanometer structure was relatively complex and difficult to maintain once a failure occurred. Summary of the invention

[0004] The purpose of the present invention is to provide a galvanometer motor and a laser scanning galvanometer. When the device is in use, the servo motor drives the two second bevel gears to rotate simultaneously through the first bevel gear of its output shaft. The staff's fingers push the stirring rod to move, and the propulsion ring at the end of the stirring rod drives the attraction block to translate and be attracted to the magnet block. Then the servo motor can drive the magnet block and the screw on its axis to rotate, and the screw drives the galvanometer at its top to translate. Whichever stirring rod the staff pushes, the corresponding galvanometer will translate, thereby achieving the effect of efficiently driving the galvanometer to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a galvanometer motor, comprising a machine frame, an assembly channel is arranged inside the machine frame, a guide rod mechanism is arranged at the bottom of the assembly channel, a laser scanning galvanometer is arranged on the guide rod mechanism, and a galvanometer motor mechanism matching the laser scanning galvanometer is arranged in the middle of the guide rod mechanism; the galvanometer motor mechanism comprises a servo motor on the inner side wall of the assembly channel, a first bevel gear is arranged on the output shaft of the servo motor, second bevel gears are arranged on the left and right sides of the first bevel gear, the second bevel gears are respectively meshed with the first bevel gears, a square shaft hole is arranged in the middle of the two second bevel gears, a square shaft is slidably inserted in the square shaft hole, an attraction block is arranged at the end of the square shaft, and a propulsion mechanism is arranged on the outer side of the attraction block; a magnet block is arranged on one side of the attraction block, a screw is arranged on the axis of the magnet block, and a threaded hole matching the screw is arranged at the bottom of the laser scanning galvanometer.

[0006] Furthermore, the guide rod mechanism includes two positioning guide rods, and the positioning guide rods are fixed on the inner side wall of the assembly channel through the end seats of the end heads thereof.

[0007] Furthermore, the propulsion mechanism includes an annular groove on the outside of the suction block, a propulsion ring is mounted inside the annular groove, a provocation rod is provided on the side wall of the propulsion ring, a propulsion groove is provided on the side wall of the frame, and two provocation rods are inserted inside the propulsion groove.

[0008] Furthermore, the end surface of the attraction block is provided with a circular array of concave stripes, and the end surface of the magnet block is provided with convex stripes matching the concave stripes.

[0009] A laser scanning galvanometer comprises a main lens, the outer side of the main lens is wrapped with an annular plastic shell, a composite mirror is arranged on one side of the main lens, a guide needle mechanism is arranged between the main lens and the composite mirror, the outer edges of the main lens and the composite mirror are tightly wrapped with a sealing film, a glue injection mechanism is arranged on the top of the sealing film, and a threaded hole and two guide rod holes are arranged at the bottom of the annular plastic shell.
