1. An insertion device comprising:
a cover body having an accommodating space; and
an insertion module disposed in said accommodating space, and including a main body, an insertion seat, a first elastic member, a retraction seat, a second elastic member, a base and a sensor assembly, said main body being coupled to said cover body, and cooperating with said cover body to define a displacement space therebetween, said insertion seat being removably positioned in said cover body, and being able to move in said displacement space between said main body and said cover body, said first elastic member having two opposite ends that respectively abut against said insertion seat and said cover body, said retraction seat being removably positioned relative to said insertion seat, said second elastic member having two opposite ends that respectively abut against said insertion seat and said retraction seat, said base being separably positioned relative to said main body, said sensor assembly being separated from said base before an automatic-insertion operation, and being driven by said insertion seat to be mounted to said base after the automatic-insertion operation, said base having a mounting portion for said sensor assembly to be separably mounted thereto, said mounting portion of said base including a recess that permits said sensor assembly to be press-fitted thereinto;
wherein, when said cover body is depressed, the insertion seat is driven by a restoring force of said first elastic member to perform the automatic-insertion operation and to collapse a first limiting structure between said insertion seat and said main body; and
wherein, after the automatic-insertion operation is completed, said cover body is positioned relative to said main body without rebounding, and a second limiting structure between said insertion seat and said retraction seat collapses upon the collapse of said first limiting structure between said insertion seat and said main body, so that said retraction seat is driven by a restoring force of said second elastic member to perform an automatic-retraction operation,
wherein said insertion seat has at least one limiting groove, said cover body has at least one limiting member that removably engages with said at least one limiting groove of said insertion seat, and said insertion seat further has at least one positioning portion that positions said retraction seat relative to said insertion seat, and
wherein, when the at least one limiting member of the cover body is disposed in said at least one limiting groove of the insertion seat, a first side of said at least one limiting member directly abuts against said at least one positioning portion of the insertion seat and a second side of said at least one limiting member directly abuts against an opposing portion of the insertion seat such that removal of said at least one limiting member from the at least one limiting groove directly causes the at least one positioning portion to undergo outward deformation into the at least one limiting groove, wherein the outward deformation of the at least one positioning portion directly releases the restoring force of said second elastic member to perform the automatic-retraction operation.
