Abstract
A safety single use blood taking lancet, having an adjustable puncture depth, includes a blast-off structure and an adjusting head. The blast-off structure comprises a sleeve, an end cap, a needle core with a needle pin, a spring and a push element. Two elastic clips extend from the end cap. The needle core and the elastic clips form a lock structure and a structure blocking the needle core to return to an initial position. An inside face has a revolving inclined plane or a revolving ladder plane. When changing the revolving angle of the adjusting head, the revolving inclined plane or the revolving ladder plane bumps into an impact face of the needle core at different depth of the needle hole.
