The invention discloses a hand-throwing-type biological tear gas bomb. The hand-throwing-type biological tear gas bomb is characterized in that the hand-throwing-type biological tear gas bomb comprises a shell, a rear cover, a spraying tank, a spring, a fixed base, a hook, a printed circuit, a battery, an intelligent electronic starting striking device and a switch, wherein the rear cover is connected with the shell, and the rear cover is provided with a sealing glue strip; the spraying tank is fixed in the shell; the spring and the fixed base are sequentially arranged at the bottom end of thespraying tank; the hook is connected with the spring; the fixed base is provided with the printed circuit; the battery is positioned on one side of the shell; the intelligent electronic starting striking device is fixed on the outer surface of the shell; and the switch is arranged on the fixed base. The hand-throwing-type biological tear gas bomb not only uses a pure biological preparation to prepare a tear medicament, has no harm to the human body and the environment, but also can carry out free combination of a single group or two groups according to requirements, and is more convenient touse; and meanwhile, the design of the intelligent electronic starting striking device improves the accuracy of the initiation time.
