Abstract
A mechanical automatic injection pen includes a first assembly and a second assembly. The first assembly includes a first pipe, a pulling assembly, a push rod, a locking assembly, a first elastic assembly, and a second elastic assembly. The second assembly includes a second pipe and an actuating assembly. The locking assembly is actuated by the actuating assembly to release the locked state of the push rod, the push rod moves along the axis toward the needle assembly through the second elastic assembly to push the medicine to perform the injection operation. After the injection operation is completed, the pulling assembly can move along the axis in a direction away from the second pipe by an external force, thereby gradually driving the push rod to return to the position before the injection operation. Accordingly, the push rod can be returned to the original position by operation of the pulling assembly.
