A cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit mounted on the rotation member and movable relative to the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction, and a locking unit mounted between the fixed unit and the movable unit to releasably lock the movable unit onto the fixed unit. Thus, the movable unit is locked onto the fixed unit by the locking unit to lock the cable tightening device and the cable so as to protect the cargo wound by the cable, thereby achieving an anti-theft purpose.

The invention claimed is: 1. A cable tightening device, comprising: a fixed unit; a rotation member rotatably mounted on the fixed unit; a movable unit mounted on the rotation member and movable relative to the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway
The invention claimed is: 1. A cable tightening device, comprising: a fixed unit; a rotation member rotatably mounted on the fixed unit; a movable unit mounted on the rotation member and movable relative to the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction; a locking unit mounted between the fixed unit and the movable unit to releasably lock the movable unit onto the fixed unit; wherein: the fixed unit includes a base member having a side formed with a protruding ear formed with a locking hole; the movable unit includes a movable member rotatably mounted on the rotation member and movable relative to the base member of the fixed unit; the locking unit includes a lock body mounted on and partially protruded outwardly from the movable member of the movable unit to move with the movable member, a linking bar mounted on the lock body and provided with a locking hook that is releasably locked in the locking hole of the base member when the movable member of the movable unit is rested on the base member of the fixed unit, and a press member movably mounted on the movable member of the movable unit and rested on the linking bar to press the linking bar so as to detach the locking hook of the linking bar from the locking hole of the base member. 2. The cable tightening device in accordance with claim 1, wherein the linking bar of the locking unit has a substantially L-shaped profile. 3. The cable tightening device in accordance with claim 1, wherein: the locking unit further includes a spring-biased mandrel movably mounted in the lock body, and a plurality of number wheels rotatably mounted on the lock body and connected to the mandrel to releasably lock the mandrel; the linking bar of the locking unit has a first section secured to a first end of the mandrel and a second section formed with the locking hook. 4. The cable tightening device in accordance with claim 3, wherein: the movable member of the movable unit has a first face facing the base member of the fixed unit and formed with a receiving chamber to receive the locking unit; the movable member of the movable unit has a sidewall formed with a receiving hole connected to the receiving chamber; the first section of the linking bar is formed with an insertion groove; the press member of the locking unit has a first end formed with a push button protruded outwardly from the receiving hole of the movable member and a second end extended into the receiving chamber of the movable member and formed with a push block inserted into the insertion groove of the linking bar. 5. The cable tightening device in accordance with claim 4, wherein: the receiving chamber of the movable member has a wall formed with a plurality of receiving slots exposed outwardly from a second face of the movable member; the number wheels of the locking unit are partially protruded outwardly from the receiving slots of the movable member. 6. The cable tightening device in accordance with claim 4, wherein the press member of the locking unit is movably mounted in the receiving hole of the movable member. 7. The cable tightening device in accordance with claim 4, wherein the locking unit further includes a cover mounted on the movable member of the movable unit to cover the lock body. 8. The cable tightening device in accordance with claim 7, wherein the cover of the locking unit is mounted in the receiving chamber of the movable member to seal the receiving chamber of the movable member. 9. The cable tightening device in accordance with claim 7, wherein the cover of the locking unit has a first end formed with an opening to allow passage of the mandrel of the locking unit. 10. The cable tightening device in accordance with claim 9, wherein the mandrel of the locking unit has a second end provided with a code adjustment member, and the cover of the locking unit has a second end formed with a breach to allow passage of the code adjustment member of the locking unit. 11. The cable tightening device in accordance with claim 4, wherein the push button of the press member is pressed inwardly to move the linking bar outwardly relative to the locking hole of the base member to detach the locking hook of the linking bar from the locking hole of the base member to unlock the movable member of the movable unit from the base member of the fixed unit. 12. The cable tightening device in accordance with claim 3, wherein the number wheels of the locking unit are rotatable between a locked position where the mandrel is locked by the number wheels so that the linking bar is fixed by the mandrel to fix the locking hook, and an unlocked position where the mandrel is unlocked from the number wheels so that the linking bar is movable with the mandrel to move the locking hook. 13. The cable tightening device in accordance with claim 1, wherein the fixed unit further includes two opposite ratchet wheels rotatably mounted on the base member and secured on the rotation member to rotate the rotation member, a stop plate movably mounted on the base member and releasably engaged with the ratchet wheels to allow the ratchet wheels to rotate in a oneway direction, a fixing seat secured on the base member, and an elastic member biased between the stop plate and the fixing seat to push the stop plate toward the ratchet wheels. 14. The cable tightening device in accordance with claim 13, wherein the base member of the fixed unit has two opposite sidewalls each formed with a guide tracks to guide movement of the stop plate. 15. The cable tightening device in accordance with claim 13, wherein the movable unit further includes a push plate movably mounted on the movable member and releasably engaged with the ratchet wheels of the fixed unit to push the ratchet wheels to rotate in a oneway direction, a fixing seat secured on the movable member, an elastic member biased between a first side of the push plate and the fixing seat to push the push plate toward the ratchet wheels of the fixed unit, and a release member mounted on a second side of the push plate to push the push plate to detach from the ratchet wheels of the fixed unit so that the push plate of the movable unit skips the ratchet wheels of the fixed unit when the movable member of the movable unit is rotatable on the rotation member. 16. The cable tightening device in accordance with claim 15, wherein the release member of the movable unit is pressed upwardly to push the push plate of the movable unit outwardly relative to the ratchet wheels of the fixed unit to detach the push plate of the movable unit from the ratchet wheels of the fixed unit so that the push plate of the movable unit skips the ratchet wheels of the fixed unit when the movable member of the movable unit is rotatable on the rotation member. 17. The cable tightening device in accordance with claim 15, wherein the movable member of the movable unit has two opposite sidewalls each formed with a guide tracks to guide movement of the push plate. 18. The cable tightening device in accordance with claim 1, wherein the rotation member is rotatably mounted on the base member of the fixed unit. 19. The cable tightening device in accordance with claim 1, wherein the movable member of the movable unit has two opposite sidewalls each formed with a pivot hole pivotally mounted on the rotation member.
