A cable guiding assembly is mounted to a cable guide seat and for extension of a cable therethrough, and includes first and second housings, a pivot connecting unit and a locking mechanism. The pivot connecting unit includes first and second pivot connecting portions disposed on and pivotably connected to the first and second housings, respectively, such that the first housing is pivotable relative to the second housing between a close position, where the first and second housings cooperatively define an accommodating space and permit the cable to extend therethrough, and an open position that permits the cable to be installed to and removed from the cable guiding assembly. The locking mechanism includes first and second locking units disposed respectively on first and second housings, respectively opposite to the first and second pivot connecting portions and detachably engaging each other to secure the first housing at the close position.

The invention discloses a rigid-flexible coupling mechanism with variable rod length for fibre bundle tension control. In the transmitting process, the fibre bundle passes through the front guide roller, the tension regulating roller and the back guide roller sequentially. The front and back guide rollers have fixed positions, while the tension regulating roller has an adjustable position to regulate the fibre bundle tension. The invention uses the variable rod length rigid-flexible coupling mechanism with a combination of a servo motor and an electric actuator in a dual drive control mode, which can choose to use either a four-rod fixed length mechanism or a five-rod variable length mechanism to regulate the tension under different working conditions. This provides a more flexible control method, increases the regulating range of fibre bundle tension, improves the system response speed and regulation accuracy, and effectively avoids the wear of fibre bundle caused by tension fluctuations.
