The invention discloses a feeder for heating a bar stock of a mini-tiller and aims to solve the problem of non-uniform heating caused by the unstable manual feeding frequency in the prior art. The feeder comprises a rack and also comprises a driving disc rotationally connected with the rack, a four indexing slot wheel rotationally connected with the rack, a first gear coaxially fixed with the four indexing slot wheel, a guide rod hinged to one end of the rack, a second gear meshed with the first gear and a work clamp connected with one end, far away from the rack, of the guide rod. The driving disc comprises a circular plate and a notch disc provided with two mutually symmetrical locking arcs; the circular plate comprises an arc section and a linear section; a first pin column and a second pin column are arranged on the position, close to the edge, of the circular plate; a third pin column is arranged at the edge of the second gear; a slideway penetrating through the guide rod is arranged in the middle of the guide rod; the third pin column slides in the slideway. A single-pole double-throw switch for controlling the rotary direction of the driving disc is arranged in the position, close to the middle of the linear section of the circular plate, on the rack. The feeder for heating the bar stock of the mini-tiller is simple in structure and strong in practicability.
