The size of the limiting counter bore 2111 of the impeller seat 211 is set to be larger than the external size of the driving seat 212, so that the driving seat 212 can synchronously drive the impeller seat 211 to rotate when rotating, and the impeller seat 211 can synchronously and axially move downwards to protect the cutter head assembly 4 from being damaged when the cutter head assembly 4 bears external pressure; and the elastic member 213 is arranged in the limiting counter bore 2111 of the impeller seat 211 and is positioned between the impeller seat 211 and the driving seat 212, so that when the external pressure born by the cutter head assembly 4 disappears, the elastic member 213 can play a reset function, the impeller seat 211 is enabled to move upwards along the axial direction of the driving seat 212 in real time to ensure that the cutter head assembly 4 is restored to a working state, and the shaving effect is ensured. In this embodiment, for convenience of production and assembly, the elastic member 213 is a spring, and the impeller seat 211 and the driving seat 212 are respectively provided with a spring seat 214 at corresponding positions, and two ends of the spring are respectively mounted on the spring seats 214 of the impeller seat 211 and the driving seat 212, so that the spring is fixed in the limiting counter bore 2111 and located between the impeller seat 211 and the driving seat 212; of course, from the technical purpose to be achieved, the elastic member 213 may also be a memory metal spring, which can achieve the same purpose and achieve the same technical effect, but the embodiment of the present embodiment is a preferred embodiment because the spring is low in production cost and is easily available in the market.

The length of the limit leg 215 is determined by the axial up-down displacement stroke of the cutter head assembly 4 and the impeller seat 211, and the specific length can be determined according to practical situations, and the embodiment is not further limited.
