[0029] How it works

[0030] When in use, first place the object to be heated 15 on the placement plate 9, then the electric telescopic rod 10 is started, and the electric telescopic rod 10 drives the movable rod 14 to move down through the mounting block 11, so that the movable rod 14 drives the supporting block 13 to be clamped on the surface of the object to be heated 15 through the fastening rod 12, and then the induction heating coil 16 heats the object to be heated 15, at the same time, the driving motor 3 is started and drives the transmission gear 4 to rotate, and the transmission gear 4 drives the screw rod 5 to rotate through the connecting gear 6, and then the sliding nut 7 drives the placement plate 9 to rise or fall through the connecting rod 8, so that the placement plate 9 adjusts the heating position of the object to be heated 15 in the induction heating coil 16.

[0031] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model.
