The present invention relates to a braking mechanism for a garden tool which includes a working shaft (42) for mounting a cutting tool. The braking mechanism comprises a working wheel assembly including an inner wheel (4) and a rotary driven outer wheel (5) enclosing the inner wheel (4) substantially coaxially, wherein in the working non-braking state the outer wheel drives the inner wheel (4) and the rotary working shaft (42) rotationally (5), a first brake member (6) and a second brake member (9) fixed to the garden tool and a resilient spring member (7) connected between the first brake member (6) and the inner wheel (5). The first brake member (6) and the second brake member (9) are separate during a normal working state of the garden tool and in contact during a braking state of the garden tool. The present invention is simple in structure and requires a small number of components to achieve an efficient braking function. |
