Patent ID: 8037973

Claim:
A fixing device for anti-slip cable lock comprising: a braking device comprising: a braking body which is a hollow member having a first end provided with internal threads and a second end provided with a through hole, said braking body having an inner inclined wall surface which converges towards said second end; a front nut cap provided with external threads engaged with said internal threads of said braking body, said front nut cap having a recess which has a seat provided with a through hole a displacement axle core which is hollow and has a threaded portion and an end adjacent to said threaded portion, said end of said displacement axle core having a plurality of holding holes, said end of said displacement axle core being fitted into said second end of said braking body through said through hole of said braking body, said threaded portion having another end provided with a blocking edge; a plurality of steel balls each fitted in a respective one of said holding holes of displacement axle core; and a tension spring having a first end and a second end, said first end of said tension spring being received in said recess of said front nut cap and bearing against said seat of said front nut cap, said second end of said tension spring bearing against said end of said displacement axle core; a locking device having a hollow body provided with internal threads which are engaged with said threaded portion of said displacement axle core, said hollow body having a limiting hole restricting said blocking edge of said displacement axle core; and a cable extending through said front nut cap, said braking body, said displacement axle core and said locking device; wherein when said braking device is at normal condition, said tension spring urges against said displacement axle core thereby causing said inner inclined wall surface of said braking body to push said steel balls against said cable thereby fixing said cable in position; when said locking device is turned to bear against said second end of said braking body, an additional locking force is provided to said cable; when desired to release said cable, said locking device is turned away from said braking body and said displacement axle core is pushed inside said braking body thereby releasing said steel balls from said inner inclined wall surface.
