Patent ID: 8728407

Claim:
A holding device, disposed in a bio-detecting instrument having a plurality of sensing terminals, for holding a test strip, the holding device comprising: a first casing; a second casing, assembled with the first casing to form an accommodating space there between, wherein the sensing terminals are extended into the accommodating space, and the test strip is configured to be delivered into the accommodating space through a first opening and contact with the sensing terminals; an ejecting member, comprising a push rod, a first stopper connected to the push rod, a second stopper, an intermediate connecting rod located between the first stopper and the second stopper and a handle portion connected to the second stopper, wherein the push rod is configured to be reciprocated in the accommodating space through a second opening, the handle portion is extended to outside of the bio-detecting instrument, and the ejecting member is integrally formed; and an elastic member, disposed between the second casing and the first stopper, wherein the elastic member is configured to be compressed by driving the ejecting member to an ejecting position, where the push rod enters the accommodating space and is adapted to push the test strip outward without being contact with the sensing terminals, and the elastic member is configured to be released by drawing the push rod back from the accommodating space to an initial position, and the elastic member is disposed in surrounding the push rod, wherein the first casing is provided with a notch for restricting strokes of the first stopper and the second stopper, the first stopper and the second stopper are respectively located at two opposite sides of the notch, and a connection line of the first stopper and the second stopper passes through the notch.
