Abstract

A detachable cap-type adjusting head of a lancing device comprises an inner adjusting core with a head in a sleeve structure. An adjusting cap similar to an outer sleeve structure is sleeved on the sleeve structure. The outer sleeve is connected with the sleeve through a spiral structure and a rotary positioning structure. The spiral structure is composed of a spiral groove and a protrusion matching with each other. One of the spiral groove and the protrusion is disposed on the inner edge of the outer sleeve. The other of the spiral groove and the protrusion is disposed on the outer edge of the sleeve. The detachable cap-type adjusting head is characterized in that a straight groove parallel with an axis of the adjusting head is disposed corresponding to the spiral groove, and one end of the straight groove is communicated with the spiral groove. When the protrusion is located at the joint of the spiral groove and the straight groove, the protrusion can slide along the straight groove by axially pulling the adjusting cap, the adjusting cap can be pulled off to clean residual blood inside the adjusting head, and the adjusting cap can be fitted on after cleaning. Accordingly, the adjusting cap at the front of the adjusting head is attachable.
