[0023] In this embodiment, Figure 2 As shown, the bottom wall of the sintering box 4 is fixedly installed with an electric heating pipe 402; it should be noted that when the operator can first put the object to be sintered on the top of the plate 7, and clamp the side wall of the object with the clamping mechanism 8, the operator can start the electric heating pipe 402 and the hot air blower in the hot air box 9 at the same time through the external controller.

At this time, the operator can simultaneously start the hot air blower and the electric heating pipe 402 in the hot air box 9, and the electric heating pipe 402 will heat the part directly below the object, while the hot air box 9 will generate hot air through the air delivery mechanism 10 connected thereto. It is transported to the interlayer of the four inner walls of the sintering box 4, and the internal hot air is discharged to the inside of the sintering box 4 through a number of ventilation holes 401 opened on the inner wall surface of the sintering box 4, and then the driving motor 2 is started to drive the object placed on the top of the plate 7 to rotate together. At this time, during the heating process of the electric heating tube 402 and the hot air box 9, the object rotating at a uniform speed can also better heat all directions evenly.
