Abstract
Abstract A dry shaving device, which comprises a driving means and a housing including a head and receiving the driving means. A cutter head is arranged above the head of the housing. The cutter head includes a knife head. A cutter sheet covers over the knife head, and a frame of the cutter head is swingably mounted at one of its ends at a lower lateral range of the head of the housing. A holding element is coordinated to the frame of the cutter head and secures the cutter sheet to the frame of the cutter head. The holding element is designed as a bow capable of being attached to the lower side of the frame of the cutter head. A bearing axle receives independently and swingably the holding element and the frame of said cutter head, and the holding element is repeatedly releasably secured to portions of the frame of the cutter head.
