, the surface of the reflector is smooth and flat.

, the angle that the mirror can rotate on the surface of the housing is 45 degrees.

, the guide rail is integrated on the bottom plate of the base and is composed of metal round tubes.

Further , the distance the housing can travel is equal to the length of the rail.

, the chip is a semiconductor element with square shape and is arranged at the right side of the bottom of the inner cavity of the shell.

, the casing is a square body with length and width of 20cm, and the thickness of the reflector is smaller than the width of the casing.

, a circular groove is arranged in the middle of the shell, and the reflector is clamped in the circular groove.

Different from the prior art, the technical scheme has the following advantages: this adjusting device of automatic focusing light path calculates information such as angle and height of laser incidence through the chip, and the angle of rethread micro motor automatically regulated reflector, elevating platform adjust focusing device's height and the electronic slip table automatically regulated focusing device's of small-size position can realize quick accurate focusing, make the regulation of laser light path simple high-efficient. This adjusting device of automatic light path of focusing through the design that adopts accurate optics electric lift platform, cooperates the used together of reflector simultaneously for the device can be to angle and highly the regulation calculation, and not only high-efficient practicality, easy operation is the embodiment of this device feasibility and practicality moreover.
