Releasing structure for lancing device
First Claim
1. A releasing structure for a lancing device, comprising:
- a lancet body with a lancet at a front of a lancing device;
a lancet holder mounted with the lancet body with the lancet at the front of the lancing device;
a stem disposed behind the lancet holder, the stem configured to move the lancet holder forward or backward;
a rotary housing operably coupled to the stem, the rotary housing configured to push or pull the stem while turning forward at a predetermined angle about a rotational axis defined in a movement direction of the lancet, wherein a first end of the stem is connected to the lancet holder by a connection pin and a second end of the stem is inserted in the rotary housing;
a torsion spring operably coupled to the rotary housing, the torsion spring configured to store torque for turning the rotary housing forward at a predetermined angle;
a loading handle operably coupled to the torsion spring, the loading handle configured to transmit torque to the torsion spring while turning forward at a predetermined angle;
a disc formed radially from a rotation center axis of the stem in the rotary housing, the disc being formed on a portion of the stem which is inserted in the rotary housing;
a forward-inclined rib formed on a rear side of the disc, the forward-inclined rib being inclined within a predetermined range of angles in the movement direction;
a backward-inclined rib formed on a front side of the disc, the backward-inclined rib corresponding to the forward-inclined rib;
a forward rib protruding at a first side on an inner side of the rotary housing with the stem inserted, the forward rib corresponding to the forward-inclined rib, the forward rib configured to push the stem forward by moving along an inclined surface of the forward-inclined rib while turning with the rotary housing; and
a backward rib protruding at a second side on the inner side of the rotary housing, the backward rib corresponding to the backward-inclined rib, the backward rib configured to push the stem backward by moving along an inclined surface of the backward-inclined rib while turning with the rotary housing.
