1. An insertion device comprising:
an upper casing including an outer shell, and a cover body that is disposed in said outer shell, said cover body having an accommodating space;
an insertion module disposed in said accommodating space, forming movement relationship with said outer shell and said cover body of said upper casing, and including a main body assembly, an insertion seat, a first elastic member, a retraction seat, a second elastic member, a base and a sensor assembly, said main body assembly including an upper portion, and a lower portion that cooperates with said upper portion to define a displacement space therebetween, said insertion seat being removably positioned in said upper portion, and being able to move in said displacement space between said lower portion and said upper portion, said first elastic member having two opposite ends that respectively abut against said insertion seat and said upper portion of said main body assembly, 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 assembly, said sensor assembly being able to be separably mounted to said base; and
a lower casing separably connected to said upper casing;
wherein, when said upper casing is depressed to move relative to said main body assembly, the insertion seat is driven by a restoring force of said first elastic member to perform an automatic-insertion operation and to collapse a first limiting structure between said insertion seat and said lower portion of said main body assembly;
said insertion device further comprising a pair of fixing members that are movably mounted to said main body assembly, said fixing members interfering with said lower casing and said upper casing before said lower casing is separated from said upper casing, so that said upper casing is prevented from moving downwardly by said fixing members and that said sensor assembly is supported by said fixing members to be positioned relative to said main body assembly to prevent unintentional insertion operation of said insertion device, when said lower casing is separated from said upper casing, said upper casing being permitted to be depressed, depression of said upper casing pushing and moving said fixing members laterally and outwardly relative to said main body assembly so as to collapse a limiting structure among said fixing members, said sensor assembly and said base.
