Lens falling resistance test device for manufacturing environment-friendly instrument

The invention provides an environment-friendly lens falling resistance test device for instrument manufacturing. An ejector rod is arranged above a movable rod, a sliding plate is arranged at the topof the ejector rod, the sliding plate is slidably installed on the upper wall of the interior of a test bin, a rack is fixedly installed at the right end of the sliding plate, and the front surface ofthe rack is engaged with a gear rod; the outer surface of the gear rod is in threaded connection with a sleeve block, a supporting rod is movably installed on the left surface of the sleeve block, and a stress table is movably installed at the tail end of the supporting rod. After the movable rod drives the impact head to impact, the ejector rod is extruded upwards, the ejector rod is clamped with an inclined groove of the sliding plate, the sliding plate and the rack are driven to move rightwards, and after the rack is meshed with the gear rod, the adjacent sleeve blocks are driven to get close to the middle by utili
