发明名称 Power Tool
摘要 A power tool has a tool unit arranged between housing and housing cover. A stud bolt secured on the housing projects through a cover opening to the exterior. A support sleeve of the housing cover is provided with the cover opening and with a support surface for a fastening element screwed onto the stud bolt to secure the housing cover on the housing. The fastening element has a first section arranged at the cover exterior and delimited by a circumferential contour with flats. A maximum radial distance of the outer circumference of the support sleeve relative to the longitudinal center axis of the stud bolt at the support surface and at an adjoining first section of the support sleeve is at most as large as half the width across flats of the fastening element; a tool engaging the flats thus fits across the first section of the support sleeve.
