After the processing is completed, the top cover 11 is taken out, and then the entire mesh tube 6 is taken out, so that the internal contacts can be poured out. Since the mesh disk 7 and mesh tube 6 can be disassembled, and the oxidation furnace mainly burns on the mesh disk 7, the degree of damage to the mesh disk 7 will be greater than that of the mesh tube 6, and the number of replacements for the mesh disk 7 will also increase. At this time, the use of this split mesh tube 6 and mesh disk 7 is convenient for replacing only the mesh disk 7, thereby reducing the cost of use.

At the same time, after the top cover 11 is placed on the net tube 6, the third handle 13 can be used to engage with the first groove 5 on the second handle 4, thereby avoiding relative rotation between the top cover 11 and the net tube 6, which may affect the normal operation of the toggle frame 9.

[0029] Furthermore, two first handles 3 are fixedly installed on the top of the furnace cover 2, and the furnace cover 2 is convenient to open by providing the first handles 3.

[0030] Furthermore, the mesh tube 6, mesh disk 7, toggle frame 9 and connecting shaft 10 are all made of high-temperature alloy steel. The use of high-temperature alloy steel can support the contacts while reducing the impact of the oxidation furnace on the contacts.

[0031] In summary, during use, the mesh disk 7 is first placed inside the mesh tube 6, and then multiple contacts are placed inside the mesh tube 6 and supported by the mesh disk 7, and the entire mesh tube 6 is placed on the furnace cover 2. At this time, the mesh tube 6 is inside the oxidation furnace, so that the internal contacts are burned and oxidized, and the top cover 11 is placed on the top of the mesh tube 6. At this time, the toggle frame 9 will be located on the surface of the mesh disk 7, and then the motor 12 is started. The motor 12 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the toggle frame 9 to rotate, thereby toggling the surface contacts so that all contacts can be fully and evenly burned. After the processing is completed, the top cover 11 is taken out, and then the entire mesh tube 6 is taken out, so that the internal contacts can be poured out. Since the mesh disk 7 and mesh tube 6 can be disassembled, and the oxidation furnace mainly burns on the mesh disk 7, the damage degree of the mesh disk 7 will be greater than that of the mesh tube 6, and the number of replacements of the mesh disk 7 will also increase. At this time, this split mesh tube 6 and mesh tube 6 are used. The two protrusions 14 provided inside the net tube 6 can support the net tube 7 so that it will not leak out from the bottom of the net tube 6. The provided plug rod 15 can be inserted into the socket 16 of the net tube 7, thereby fixing the net tube 7 and avoiding the instability caused by the movement of the net tube 7 when the toggle frame 9 to toggle the contact. By providing the second handle 4, it is convenient to remove the net tube 6 directly from the furnace cover 2, and the third handle 13 is convenient to remove the entire top cover 11 from the net tube 6. At the same time, after the top cover 11 is placed on the net tube 6, the third handle 13 can be used to engage with the first groove 5 on the second handle 4, so as to avoid relative rotation between the top cover 11 and the net tube 6, which affects the normal operation of the toggle frame 9. By providing the first handle 3, it is convenient to open the furnace cover 2.
