A cable tightening device includes a fixed unit including a base, a rotation member rotatably mounted on a first end of the base, a movable unit including a movable member rotatably mounted on the rotation member and movable relative to the base, and a holding member secured on a second end of the base. Thus, the base of the fixed unit is integrally combined with the holding member without having to provide a bolt and a nut, thereby decreasing the costs of fabrication. In addition, the holding member is integrally combined with the base of the fixed unit by punching so that the holding member will not detach from the base of the fixed unit, thereby facilitating operation of the cable tightening device.

The invention claimed is: 1. A cable tightening device, comprising: a fixed unit including a base; a rotation member rotatably mounted on a first end of the base of the fixed unit; a movable unit including a movable member rotatably mounted on the rotation member and movable relative to the base of the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction; a holding member secured on a second end of the base of the fixed unit; wherein the base of the fixed unit has two opposite sidewalls and a bottom wall located between the two opposite sidewalls; the holding member is located between the two sidewalls of the base; each of the two sidewalls of the base is provided with a locking slot; the holding member is inserted into the locking slot of each of the two sidewalls of the base; the holding member has two opposite sides each having two opposite ends each provided with a bent locking piece protruding outwardly from the locking slot of a respective one of the two sidewalls of the base and closely locked onto an outer face of the respective sidewall of the base. 2. The cable tightening device of claim 1, wherein the holding member has two opposite ends each provided with at least one cutout located beside the bent locking piece to define the bent locking piece. 3. The cable tightening device of claim 2, wherein the cutout of the holding member is connected to the locking slot of the respective sidewall of the base. 4. The cable tightening device of claim 2, wherein the holding member has a hollow inside provided with an opening connected to the at least one cutout and directed outwardly and rearward relative to the rotation member. 5. The cable tightening device of claim 1, wherein the holding member has a substantially U-shaped profile. 6. The cable tightening device of claim 1, wherein the holding member has a substantially J-shaped profile. 7. The cable tightening device of claim 1, wherein the holding member has a substantially oblong profile. 8. The cable tightening device of claim 1, wherein the locking slot of each of the two sidewalls of the base has a shape matching a cross-sectional profile of the holding member. 9. The cable tightening device of claim 1, wherein the two opposite sides of the holding member are spaced from each other. 10. The cable tightening device of claim 1, wherein each of the two opposite sides of the holding member is a flat sheet plate. 11. The cable tightening device of claim 1, wherein the holding member locked between the two sidewalls of the base and is combined with the base integrally. 12. The cable tightening device of claim 1, wherein the holding member is disposed at a transverse state and is parallel with and spaced from the bottom wall of the base. 13. The cable tightening device of claim 1, wherein the base of the fixed unit is made of a metallic sheet plate; the base of the fixed unit has a substantially U-shaped profile; the bottom wall of the base has a solid structure. 14. A cable tightening device, comprising: a fixed unit including a base; a rotation member rotatably mounted on a first end of the base of the fixed unit; a movable unit including a movable member rotatably mounted on the rotation member and movable relative to the base of the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction; a holding member secured on a second end of the base of the fixed unit; wherein the holding member is a flat sheet plate; the cable tightening device further comprises a soft protective jacket mounted on the holding member to surround a periphery of the holding member. 15. The cable tightening device of claim 14, wherein the protective jacket is located between the two sidewalls of the base; the protective jacket has two opposite ends each abutting an inner face of a respective one of the two sidewalls of the base. 16. The cable tightening device of claim 14, wherein the protective jacket has a substantially U-shaped profile; the protective jacket has a hollow inside provided with a receiving groove to receive the holding member. 17. The cable tightening device of claim 16, wherein the receiving groove of the protective jacket is directed outwardly and rearward relative to the rotation member.
