1. An outer shell member positioning device mountable at an outer shell member and adapted for locking an inner shell member to said outer shell member, comprising: a mounting base member mountable at said outer shell member, said mounting base member comprising an elongated accommodation open chamber, pivoting means disposed adjacent to one end of said elongated accommodation open chamber, and a retaining hole disposed adjacent to an opposite end of said accommodation open chamber;a bracket receivable in said elongated accommodation open chamber, said bracket comprising a base panel, two opposing constraint bars obliquely downwardly extended from said base panel and pivotally coupled to said pivoting means of said mounting base member and engageable into a locating hole in said inner shell member to lock said inner shell member to said outer shell member, a box track formed integral with said base panel at a location remote from said constraint bars, a sliding space defined in said box track, two elongated sliding slots respectively formed in two opposite lateral sides of said box track, and a positioning hole vertically cut through opposing top and bottom walls of said base panel in communication with said sliding space;a sliding hook member comprising a base plate slidably inserted into said sliding space in said box track of said bracket, two first hook bars respectively and forwardly extended from two opposite lateral sides of said base plate and respectively coupled to said elongated sliding slots of said bracket, and a second hook bar downwardly extended from a front side of said base plate between said first hook bar and extending in a perpendicular direction relative to said first hook bars and adapted for hooking in said retaining hole to secure said bracket inside said elongated accommodation open chamber of said mounting base member; anda locking device comprising a lock cylinder mounted in said positioning hole of said bracket, and a locking latch fastened to said lock cylinder and rotatable with said lock cylinder relative to said bracket between a locking position where said locking latch is stopped against the front side of said base plate of said sliding hook member to hold said second hook bar of said sliding hook member in engagement with said retaining hole of said mounting base member and an unlocking position where said locking latch is released from the front side of said base plate of said sliding hook member for allowing movement of said sliding hook member relative to said bracket to disengage said second hook bar from said retaining hole of said mounting base member. 2. The outer shell member positioning device as claimed in claim 1, wherein said mounting base member further comprises an opening cut through a bottom wall thereof and disposed in communication with one end of said accommodation open chamber for the passing of said constraint bars; said pivoting means of said mounting base member comprises a pivot pin inserted through said constraint bars of said bracket to pivotally couple said bracket and said mounting base member together, and a torsion spring mounted on said pivot pin and stopped between said bracket and said mounting base member and adapted to impart a biasing force to said bracket to move said bracket out of said accommodation open chamber. 3. The outer shell member positioning device as claimed in claim 2, wherein said bracket comprises two side panels respectively downwardly extended from a bottom wall of said base panel and symmetrically disposed at two opposite lateral sides, two pivot holes respectively located in said side panels and pivotally coupled to said pivot pin of said mounting base member. 4. The outer shell member positioning device as claimed in claim 1, wherein said box track defines a bottom opening cut through a bottom wall thereof in communication with said sliding space for the passing of said second hook bar of said sliding hook member. 5. The outer shell member positioning device as claimed in claim 1, wherein said positioning hole defines therein two stop edges and a circularly arched sliding way between said two stop edges; said lock cylinder of said locking device further comprises a stop block located at the periphery thereof and movable in said circularly arched sliding way of said positioning hole between said two stop edges subject to movement of said locking latch with said lock cylinder between said locking position and said unlocking position. 6. The outer shell member positioning device as claimed in claim 1, wherein said bracket further comprises a stub tube vertically downwardly extended from the bottom wall of said base panel around said positioning hole and suspending in said sliding space, and a spring member mounted around said stub tube and having two opposite ends thereof respectively stopped against said base plate of said sliding hook member and an inside wall of said bracket inside said sliding space. 7. The outer shell member positioning device as claimed in claim 1, wherein each said first hook bar has a distal end thereof terminating in a hooked tip adapted for hooking in one said elongated sliding slot; said second hook bar has a distal end thereof terminating in a hooked tip adapted for hooking in said retaining hole of said mounting base member. 8. The outer shell member positioning device as claimed in claim 1, wherein said lock cylinder of said locking device comprises a locating shank located at a bottom side thereof; said locking latch of said locking device comprises a mounting hole located at one end thereof and fastened to said locating shank of said lock cylinder.
