Laser foreign body cleaning device based on accurate aiming of spiral lever final motion mechanism

The invention discloses a laser foreign body cleaning device based on accurate aiming of a spiral lever final motion mechanism. The device comprises a fixed plate, a collimator fixed block, a shaft end connecting device, a reading hand wheel, a hand wheel copper sleeve, a rotating shaft, a sliding sleeve, a laser collimator, an electronic microscope, an electronic microscope connecting part and asighting device; the manner of combining a final motion screw with a lever is adopted for adjusting the direction of the laser collimator, the sensitivity is high, the minimum displacement amount of afinal motion device can meet the aiming need of the laser foreign body cleaning device, the aiming precision is high, the distance between a cleaned target and the device only needs to be measured, the reading hand wheel is rotated to corresponding scales, the device can be aimed at a target, the aimed target position completely coincides with the laser cleaning position, and operation is easy and convenient. 种基于螺旋杠杆微动机构精
