Discharging device for blood taking needle assembly line and blood taking needle assembly line

The utility model discloses a discharging device for a blood taking needle assembly line and the blood taking needle assembly line. The discharging device for the blood taking needle assembly line comprises a grabbing mechanism used for grabbing a blood taking needle from the blood taking needle assembly line and releasing the grabbed blood taking needle in the horizontal direction, a rotating mechanism used for driving the grabbing mechanism to rotate in a reciprocating mode, a positioning mechanism used for connecting and positioning the rotating mechanism, and a swing mechanism used for driving the rotating mechanism to rotate in a reciprocating mode. The output end of the swing mechanism is connected with the input end of the rotating mechanism and drives the output end of the rotating mechanism to rotate in a reciprocating mode, the rotating mechanism is rotatably mounted on the positioning mechanism, the grabbing mechanism is mounted at the output end of the rotating mechanism, the grabbing end of the grabbing mechanism is overhung outside the mounting end of the grabbing mechanism, and the grabbing end of the grabbing mechanism rotates and swings in a reciprocating mode along with the rotating mechanism.
