Title:
HAND-HELD TOOL
Document Type and Number:
WIPO Patent Application WO/2019/194036
Kind Code:
A1
Abstract:
When performing an operation at a high place using a hand-held tool such as a disk grinder, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool such as a tether strap. When there is an even where a coupling part that couples a fall prevention suspension tool is damaged, the event is notified to an operator to reliably implement the inherent suspension function of the suspension tool. When shock is applied to a coupling member (21) via a suspension tool (S), the coupling member (21) is displaced to a second position due to deformation of a first position holding member (22), and a conduction part (31c) deviates from contact parts (31a, 31b) and a power circuit is disconnected, thereby limiting activation of a main body part (3).
