Claim 18:
19. An insertion method of a sensor, comprising:
an upper casing including an outer shell, and a cover body that is disposed in the outer shell;
an insertion device forming movement relationship with the outer shell and the cover body of the upper casing, and including a displacement space that is cooperatively defined by a main cover and a main body;
an insertion module disposed in the displacement space, the insertion module being movable in the displacement space by pre-compressed first and second elastic members therein so as to perform an automatic-insertion operation and an automatic-retraction operation;
an insertion limiting structure disposed between the insertion module and the main body for removably positioning the insertion module at a pre-insertion position; and
a retraction limiting structure disposed between the insertion module and the cover body, a portion of the insertion module being able to move from a post-insertion position to the pre-insertion position when the retraction limiting structure is collapsed,
wherein, when the insertion device is kept being depressed after the upper casing is depressed to move relative to the main body, the insertion limiting structure is collapsed, and the insertion module is biased by a restoring force of the first elastic member to move downwardly to perform the automatic-insertion operation, the retraction limiting structure being collapsed immediately after the insertion module finishing the automatic-insertion operation, such that the insertion module is biased by a restoring force of the second elastic member to move upwardly to perform the automatic-retraction operation, the insertion module positioning a sensor assembly thereof onto a base during the automatic-insertion operation, a time needed for performing the automatic-insertion operation and the automatic-retraction operation being no more than 100 milliseconds, and
wherein said upper casing has at least one casing engaging structure, said main body having at least one body engaging structure, said at least one casing engaging structure engaging said at least one body engaging structure when said insertion limiting structure collapses, so that said upper casing is prevented from rebounding relative to said main body.
