The lancet body is fixed inside the lancet handle and the needle tip extends out of the first end of the lancet handle to be inserted into the lancet cap. The body of the lancet cap is a block structure, which includes a first face and a second face. Both the first face and second face are flat and opposed such that when one face faces upwards, the other face faces downwards and the included angle between them in space is less than 45°; the first face is provided with a first blind hole and the second face is provided with a second blind hole and both the first blind hole and the second blind hole match the first end of the lancet handle in respect of connection relationship. In the block structure, except the first face and the second face, the other external surfaces are arcuate faces protruding outward and/or angular faces protruding outward.
