A hidden cable fixed device comprises a seat body, a movable handle provided
in
the seat body and sliding upward and downward with two springs, and a coupling
member lodged in the inner wall of the seat body and coupled to a longitudinal
track at the side wall of the movable handle. The longitudinal track has two substantially
V-shaped parts as a positioning section and a guiding section. The coupling member
is adapted to guide movement of the track of the movable handle and to selectively
lock the movable handle between the extended operative position and the received
non-operative position.
