FIELD: hand tools.

SUBSTANCE: invention relates to hand impactor tools, particularly, to axes. Hand-held impactor tool comprises a working member with a hole, in which the end of the tool handle is installed, and is fixed on the handle by means of a fixing element located on the side part of the working member in the form of a through hole with a fastening element installed in the above hole. Through hole is made on the lateral working part of the working member on the side of the handle. On the inner surface of the working element hole towards the working part there is a longitudinal blind slot for the whole width of the working part, which divides it into two identical parts, not more than half the length of the working element working part, crossing the through hole perpendicularly. Fastening element is made in the form of bolt connection, with installation of bolt head in hexagonal blind hole not less than hexagon of bolt head flush with upper part of head with outer side surface of working part of working element. Nut of the bolt connection is installed in a blind round hole in diameter which is larger than the hexagon of the nut, in the tightened position it is flush with the end of the nut and the threaded end of the bolt with the outer side surface of the working part of the working element. Side surface of working element hole is made different from smooth, for example, rough, in the form of protrusions on the surface facing inside the hole with tips. Groove width is not less than sum of heights of protrusions on inner side surfaces of working element hole. Ledges on inner side surfaces of working element hole are made in staggered order.

EFFECT: expansion of operational capabilities due to increased reliability of attachment of the working element to the handle, excluding unauthorized slipping of the working element from the handle during operation.
