Problems solved by technology

[0004] Motorcycle industry operators have developed a magnet anti-theft lock, as shown in Figures 2 and 3, the matching magnet anti-theft lock key, such as the invention patent of Taiwan Patent I246554, has an integrally formed ignition key 1. One end is provided with a gripping portion 12, and one side of the gripping portion 12 is provided with a fitting opening 131, the fitting opening 131 can be inserted into a magnetic key 2, and one end of the magnetic key 2 is provided with a pin 22, An embedded block 221 protrudes from the pin 22, so that the embedded block 221 can be fastened in a groove 132 provided on the inner side of the sleeve opening 131, so that the magnetic key 2 can be fixed on the holding portion 12, However, the structure of the magnetic key 2 is complicated, and the industry often needs to spend a lot of manpower and material resources to maintain the smoothness of the production line when preparing materials or manufacturing molding. In addition, the price after the cost is transferred is expensive, which is not easy to attract consumers.

[0005] Therefore, by the above-mentioned examples, when one of the handle portion 102 or the iron handle portion 101 of the key structure is damaged, since the handle portion 102 and the iron handle portion 101 cannot be separated, the key must be The structure 100 is replaced as a whole. Therefore, with the continuous innovation of various improved key products, whether the key products attached to the motorcycle anti-theft lock in the future have the advantages of convenience and low cost has become an important factor for consumers to consider when buying motorcycles. Therefore, how to develop a detachable key structure to meet consumers' expectations and improve market competitiveness is an urgent and important issue for related companies.
