Immune protein injection pump

The utility model relates to the technical field of injection pumps, in particular to an immune protein injection pump which comprises a shell, a sealing cover is fixed to an opening of the shell, a left groove and a right groove are formed in the sealing cover, and a left injection cylinder and a right injection cylinder are inserted into the left groove and the right groove respectively. A left piston and a right piston are slidably connected into the left syringe and the right syringe respectively, two pushing assemblies are arranged in the shell, the end faces, close to the sealing cover, of the left piston and the right piston extend to form connecting screw rods, and the connecting screw rods on the left piston and the right piston are connected with the pushing assemblies respectively. A driving mechanism for driving the two pushing assemblies to operate is arranged in the shell, so that the driving mechanism can respectively drive the two pushing assemblies to operate independently or drive the two pu
