This invention discloses a hose or cable reeler that can retract a hose or cable without the need for a retracting coil spring. The reeler generally comprises a reeling wheel assembly and a reeling wheel drive. The reeling wheel assembly is detachably coupled with the reeling wheel drive by means of a clutch. The reeling wheel drive mainly comprises a gear transmission chain, and is operated through a lever by manpower (e.g., treading of a foot). Since manpower is used to retract the hose or cable, this invention avoids the related problems that may occur when the retraction is achieved completely relying on the coil spring. For example, the disordered brandish, which may occur owing to an excessive retractive force, can be avoided during the retraction of the hose or cable, and a combined drive of manpower and retractive force of the coil spring is possible. Therefore, the hose (cable) reeler of this disclosure allows for an operation of the hose or cable in a relatively laborsaving, convenient and safe manner.
