1. A lancing device for inserting a lancet and triggering the lancet to collect blood, the lancing device comprising:
- a housing;
a lancet holder disposed in the housing, wherein the lancet holder can move from a to-be-triggered position to a triggered position for triggering the lancet to collect blood, the lancet holder comprises;
a lancet fixing mechanism for fixing the lancet when the lancet holder has the lancet inserted therein and moves to the to-be-triggered position;
a to-be-triggered position locating device for positioning the lancet holder at the to-be-triggered position; and
a retracting mechanism for retracting the lancet holder to a to-be-withdrawn position when the lancet holder had moved to the triggered position and collected blood, the retracting mechanism comprising;
an elastic element, wherein the elastic element is pressed by a ramp member of the housing to accumulate an elastic force when the lancet holder moves to the trigged position;
the elastic element provides the elastic force to retract the lancet holder to the to-be-withdrawn position;
a triggering mechanism for triggering the lancet holder to move from the to-be-triggered position to the triggered position to enable the lancet to collect blood, the triggering mechanism comprising;
a triggering force providing device for providing a triggering force to move the lancet holder from the to-be-triggered position to the triggered position; and
a releasing device for releasing the lancet holder from the to-be-triggered position to let the triggering force move the lancet holder to the triggered position; and
a withdrawing mechanism for withdrawing the lancet, wherein the withdrawing mechanism comprises;
a withdrawing rod for pushing the lancet from a to-be-withdrawn position to a withdrawn position to withdraw the lancet;
a restoring device for restoring the withdrawing rod to an initial position after the lancet has been withdrawn; and
a force applying device connected with the withdrawing rod, the force applying device being provided for a user to apply a force to move the withdrawing rod.
