A delivery apparatus (100), comprising a hook mechanism (10) and an ejection mechanism (20), the ejection mechanism (20) being movable relative to the hook mechanism (10), such that a cover body of a hook-like lever (11, 11a, 11b) of the hook-like mechanism and a second groove (211, 211a, 211b) of an ejecting lever (21, 21a, 21b) received in the hook-like lever (11, 11a, 11b) can form an openable accommodating space. Compared to the prior art, the delivery apparatus (100) connects with a medical appliance (200), when delivering the medical appliance (200), by means of the openable accommodating space formed by the distal end of the hook-like mechanism and the distal end of the ejection mechanism (20), and can not only axially limit but radially limit the medical appliance (200), improving the controllability and security of the delivery.
