The invention provides a nozzle actuating mechanism with simple structure in an automatic sorting machine capable of causing a nozzle to move with high speed and being replaced into miniaturized electronic component. The nozzle actuating mechanism comprises: a parallelogram connecting rod mechanism (10), a nozzle (11) and servo motors (13, 14); the parallelogram connecting rod mechanism comprise a swiveling jib (2) and a connecting bar (3) corresponding to long connecting bars, and a pair of swing arms (8, 9) corresponding to short connecting bars, wherein the pair of swing arms connects the swiveling jib with the proximal end of the connecting bar and connects the swing arms with the distal end of the connecting bar through pivots; the nozzle is installed on the swiveling jib on the extension line of the swing arm connecting the swiveling jib with the distal end of the connecting bar; the pivots of the swiveling jib and the proximal end of swing arm at the other side have shared fixed axis (12); and the servo motors respectively enables the swiveling jib having the function of the parallelogram connecting rod mechanism and the swing arm at the other side to move by using the shared fixed axis as the center. |
