Abstract
A work tool and transmission system thereof. The transmission system comprises: a first shaft () and a second shaft (), a near end () of the second shaft having a first mating part; a shaft coupler (), a far-side part () of the shaft coupler having a second mating part matched in shape to the first mating part; and a coupling mechanism capable of directly or indirectly applying a coupling force to at least one of the first shaft, the second shaft and the shaft coupler; when the far-side part of the shaft coupler is aligned with the near end of the second shaft in the circumferential direction, the coupling force forces the first mating part to engage with the second mating part, so that the shaft coupler transmits rotational movement of the first shaft to the second shaft. The work tool comprises: a transmission system; a motive power head transmission-connected to the first shaft (); and a working head transmission-connected to the second shaft ().
