[0002] With the rapid development of mechanical manufacturing technology, the processing and application of aluminum alloy thin-walled parts are becoming more and more extensive, especially in the automotive manufacturing industry and the aerospace industry. Taps are needed when processing aluminum alloy thin-walled parts to process the internal threads of aluminum alloy thin-walled parts.

[0003] After searching, the patent number CN202322403066.2 discloses a tap for processing internal threads of sheet metal parts. This solution combines the working main cone and the connecting rod with screws. When the working main cone or the connecting rod is damaged, only a new working main cone or connecting rod needs to be replaced, thereby reducing the overall cost. However, this combination method has certain shortcomings. First, it is inconvenient to connect and fix by means of screws. During operation, tools are often required to install and fix the screws, and multiple screws are required to connect the components. The operation is not convenient, and the main cone cannot be quickly disassembled and replaced. Therefore, it needs to be improved. Utility Model Content

[0030] It should be noted that the main cone 1 is used for thread processing of aluminum alloy thin-walled parts, and the connecting rod 6 is used for assembling and fixing the main cone 1. By arranging a plug column 4 on one side of the main cone 1, the plug column 4 is inserted into the inner wall of the annular body 5 to realize the assembly between the main cone 1 and the connecting rod 6. A cavity 10 is opened at the center of the connecting rod 6 for installing components such as the screw rod 15. A protective cylinder 18 is integrally formed on one side of the connecting rod 6.
