发明名称 Guard anti-rotation lock
摘要 A system for a hand-held power tool has a tool housing, a receiving unit fixed to the tool housing and a guard unit connected with the hand-held power tool. The guard unit includes a guard extending at least partially around a rotatable tool. A guard anti-rotation lock device includes a clamping band fixedly connected to the guard that establishes a frictional connection between the guard unit and the receiving unit. The receiving unit includes a receiving flange and a connecting element that are together surrounded by and clamped in a clamping region by the clamping band to effect the frictional connection. In a case where the rotatable tool bursts into pieces during operation, the connecting element counteracts rotational movement of the guard unit with respect to the receiving unit by changing a cross-sectional shape of the clamping region.
