The first elastic piece 613 is arranged because the first elastic piece 613 is thin and is easy to loosen after long use and cannot rotate synchronously with the outer shaft core 2, so that the first elastic piece 613 needs to be installed by the first synchronizing piece 612, that is, the first elastic piece 613 and the outer shaft core 2 are ensured to act synchronously by the first synchronizing piece 612, thereby ensuring the stability of control.
