Due to the foam material used as such, it can be firmly fixed to the oscillator by its own elasticity. Meanwhile, when moving downwards, the first fixing ring 303, the second fixing ring 305, the third fixing ring 308, the fourth fixing ring 311 and the fifth fixing ring 314 can be subjected to upward friction force, so that the tendency of driving the first fixing ring, the second fixing ring and the third fixing ring to move upwards is provided, but the limiting positions of the first limiting block 302, the second limiting block 304, the third limiting block 307, the fourth limiting block 310 and the fifth limiting block 313 can not move upwards, so that the fixing assembly 3 is fixed and stable, and the starting of the oscillator to perform oscillation operation is facilitated.

It is easy to understand that according to the specification of different oscillators, the different numbers of fixing rings of the sleeve can be flexibly replaced to meet the size requirement, so that the oscillator can be used for oscillators with different specifications on the market.
