The invention discloses an adjustable automatic wire feeding device, and mainly relates to the field of power construction facilities. The adjustable automatic wire feeding device comprises a drive mechanism and a driven mechanism. The drive mechanism is connected to one side of the driven mechanism in a hinged manner, and a limiting pin used for fixing the hinge angle is arranged at the hinged position. The drive mechanism is provided with a power wheel driven by a motor, and a first clamping wheel in reverse transmission through a planetary wheel set so that a cable can be clamped and conveyed, and the driven mechanism is provided with a fixed wheel and a second clamping wheel matched with the fixed wheel so that the turning angle can be assisted. The adjustable automatic wire feeding device has the beneficial effects that the adjustable automatic wire feeding device can be easily matched with various complex power transmission lines to finish line conveying, and meanwhile the cable can be well protected.
