The invention provides an anti-rebound method for a spiral coil. The method comprises the following steps of drying an insulating paper tube, and penetrating a winding mold into the dried insulating paper tube; sticking the insulating stays, namely sticking the plurality of insulating stays on the peripheral surface of the insulating paper tube in an annular manner at intervals, and binding and fixing the plurality of insulating stays through a first contraction band; winding: winding at least one wire on the outer sides of the plurality of insulating supporting strips in a spiral manner; and binding: binding the plurality of spiral coils formed by the wires. According to the anti-rebound method for the spiral coil provided by the invention, the compressive strength of the whole body after the insulation paper tube and the insulation stays are connected can be enhanced, meanwhile, the wire is bound, the stays can be prevented from stress deformation, meanwhile, the wire can be prevented from self-rebound, and
