Abstract
The invention discloses an ultrathin double-layer child-mother clipper lifter which comprises a bottom plate, a first drive oil cylinder, a second drive oil cylinder, a lower clipper fork frame, a first panel, a third drive oil cylinder, an upper clipper fork frame and a second panel. The lower clipper fork frame is connected with the bottom plate and the first panel. The first drive oil cylinder and the second drive oil cylinder drive the lower clipper fork frame through a drive frame at the same time to lift the first panel. The upper clipper fork frame is connected with the first panel and the second panel, and the upper clipper fork frame is driven by the third drive oil cylinder to lift the second panel. According to the lifter, the unique design of the oil cylinders on the two sides is adopted, and therefore the lifter has good lifting force, safety and stationarity, the smallest height of 140 mm can be achieved when the overall lifter is in the initial state, and the initial angle of the drive oil cylinders can be almost 0 degree; and by means of the adopted drive frame, the drive oil cylinders can have a certain angle in the initial state, a lower outer supporting frame and a lower inner supporting frame can fast intersect and be separated, and therefore lifting is completed, and good working efficiency is achieved.
