    • A brake assembly (1) for a hand-held power-driven cutting device (2) is provided comprising a movably arranged lever (14), at least being movable between a first- and a second position, a brake member (16), and a brake element (20) connected to or forming one unit with a rotatable part (22) of a transmission of the cutting device (2), wherein the brake member (16) is movable between a non-activated position and an activated position, and wherein the brake member (16) is arranged to engage with the brake element (20) in the activated position to prevent rotation of the rotatable part (22). The brake assembly (1) further comprising a holding mechanism (23) arranged to hold the brake member (16) in the non-activated position when the lever (14) is in the first position, and a first resilient element (18) arranged to bias the brake member (16) towards the activated position, and wherein the brake member (16) is arranged to be released from the holding mechanism (23) as a response to the lever (14) coming into the second position, and wherein when released the brake member (16) is adapted to be forced towards the activated position by means of the first resilient element (18), and wherein the brake member (16) is arranged to engage with a structure (34) of the brake element (20) in said activated position so as to prevent rotation of the brake element (20).
    • 一种用于手持式动力切割装置(2)的制动组件(1),其包括至少可在第一和第二位置之间移动的可移动布置的杆(14),制动构件(16), 以及与所述切割装置(2)的变速器的可旋转部分(22)连接或形成一个单元的制动元件(20),其中所述制动构件(16)可在非起动位置和致动位置 ,并且其中所述制动构件(16)布置成在所述致动位置与所述制动元件(20)接合,以防止所述可旋转部件(22)的旋转。 所述制动组件(1)还包括保持机构(23),所述保持机构(23)被布置成当所述杆(14)处于所述第一位置时将所述制动构件(16)保持在所述非启动位置,并且所述第一弹性元件(18) 将制动构件(16)偏压到致动位置,并且其中制动构件(16)被布置成作为响应于进入第二位置的杆(14)的从保持机构(23)释放的,并且其中 当释放时,制动构件(16)适于通过第一弹性元件(18)被迫朝着致动位置,并且其中制动构件(16)布置成与制动元件(16)的结构(34)接合, (20)处于所述致动位置,以防止制动元件(20)旋转。
