The invention discloses an ejecting and positioning structure for ejecting out a jig on an assembly line. The ejecting and positioning structure comprises a bottom plate, a top plate arranged on the bottom plate, a blocking cylinder arranged on the lower side of the top plate and provided with a telescopically-moving stop lever, an ejecting cylinder fixed to the bottom plate and provided with a telescopically-moving ejector rod, and a plurality of clamping cylinders arranged on the two lateral sides of the top plate correspondingly and connected with clamping plates, wherein the stop lever penetrates through one end of the top plate, the ejector rod penetrates through the top plate, and the clamping cylinders control the clamping plates to move. The ejecting and positioning structure integrates blocking, ejecting and positioning, the jig can be used without changing the size no matter how a product changes, no redundant linings, pins or other standard components are needed, and cost issaved.
