Portable induction heating coil capable of stretching out and drawing back automatically

The invention discloses an automatically telescopic portable induction heating coil which is composed of a first coil, a second coil, a third coil and a fourth coil, under the action of a first shaft controller and a second shaft controller, a first middle section connecting piece and a second middle section connecting piece rotate to drive the first coil and the second coil to rotate and contract downwards, so that the induction heating coil is automatically telescopic. Under the action of a third shaft controller, a third coil and a fourth coil are made to rotate through a coil bottom fixing shaft, finally, the full-contraction folding state of the coils is completed, the automatic contraction function is achieved, and the working efficiency can be effectively improved; the coil is completed from an extension state to a contraction state, a two-dimensional plane circle is changed into an ellipse with the size nearly 1/8, the use area is effectively utilized, and the coil is convenient to store and carry; th
