具有负载减轻系统的动力工具的绳索附接组件
摘要：
一种便携式动力工具，包括工作工具组件(5)、本体(4)、细长导杆(2a)、负载减轻系统(3)，该负载减轻系统包括背带(3d)、支撑框架(3a、3b)以及绳索(11)。绳索(11)布置成将导杆(2a)与支撑框架(3a、3b)互连。该绳索布置成通过绳索附接组件(100)连接至支撑框架(3a、3b)，该绳索附接组件具有绳索夹紧部(13)以及绳索通过部(14)，该绳索夹紧部布置成用于夹紧绳索的一部分(11a)以将绳索(11)固定至支撑框架(3a、3b)，绳索(11)可穿过该绳索通过部以从支撑框架(3a、3b)中释放绳索(11)。绳索附接组件(100)构造成当在第一方向上作用在绳索(11)的被夹紧部分(11a)上的力(F1)超过预定的阈值时，促使绳索(11)的被夹紧部分(11a)的从绳索夹紧部(13)至绳索通过部(14)的自动移动。
摘要（英）：

A portable power tool comprising a working tool assembly (5), a body (4), an elongate guide rod (2a), a load relieving system (3) comprising a harness (3d), a support frame (3a, 3b), and a cord (11). The cord (11) is arranged to interconnect the guide rod (2a) and the support frame (3a, 3b). The cord is arranged to be connected to the support frame (3a, 3b) by means of a cord attachment assembly (100) having a cord clamping portion (13) arranged to clamp a portion (11a) of the cord so as to fix the cord (11) to the support frame (3a, 3b), and a cord passage portion (14) through which the cord (11) may pass so as to release the cord (11) from the support frame (3a, 3b). The cord attachment assembly (100) is configured so as to actuate automatic movement of the clamped portion (11a) of the cord (11) from the cord clamping portion (13) to the cord passage portion (14) when a force (F1) acting on the clamped portion (11a) of the cord (11) in a first direction exceeds a predetermined threshold value.
