A hose frame assembly includes a pipe body, a wheel disc, a tensile adjusting device, and a cable. The pipe body includes three aligned pipe sections, and two resilient joints connected between every adjacent two of the three pipe sections. The tensile adjusting device is located between the pipe body and wheel disc, and includes a guide rail, two sliding members slidably mounted to the guide rail, and a resilient member connected between the sliding members. A wheel is rotatably mounted to each of the sliding members. Two ends of the cable extend through the pipe sections and the resilient joints and spacedly are fixed to an inner wall of one of the pipe sections located at a far end of the pipe body. A portion of the cable located out of the pipe body is positioned around the wheel disc and the wheels. |
