摘要： A tool holder (2) for an electrically powered hammer comprising: a tube-like tool holder body (66) which can be fitted to the front of the hammer and having a forward end for non-rotatably receiving a shank (3) of a tool or bit wherein said forward end is formed with a single axially extending slot (10); a single locking body (54) extending through said slot for releasably engaging an axially extending closed groove (88) formed in a tool fitted in said forward end of the tool holder body (66); and a locking ring (52) which surrounds the tool holder body and in a locked position locks the locking body in a radially inward position in which the locking body is engageable with the groove in the tool and in a release position allows the locking body to move into a radially outward position to allow a tool to be inserted into or removed from the forward end of the tool holder body. The locking ring (52) is shiftable in a direction transverse to the fore-aft axis of the tool holder body to allow the locking body to move into a radially outward position. A manually actuable tool release member (50) can be actuated to move the locking ring (52) between the locked position and an intermediate position, in which intermediate position the locking ring is shiftable in a direction transverse to the fore-aft axis of the tool holder body to its release position to allow the locking body to move into a radially outward position. In the locked position the locking ring (52) engages a protrusion (55) on the tool release sleeve in order to lock the locking ring in its locked position.

摘要： A tool holder for a hammer comprises a tool holder body having a forward end for non-rotatably receiving a shank of a tool. The tool holder body defines an axially extending slot. A locking body extends through the slot for releasably engaging an axially extending closed groove formed in the tool shank. A locking ring surrounds the tool holder body and in a locked position holds the locking body in a radially inward position in which the locking body engages the groove in the tool and in a release position allows the locking body to move into a radially outward position so that a tool can be inserted into or removed from the tool holder body. The locking ring is shiftable in a direction transverse to the fore-aft axis of the tool holder body to allow the locking body to move into a radially outward position.

摘要： A device for transmitting a rotary and/or percussive movement to a tool is formed in such a way that the associated tools having three grooves arranged in rotationally symmetrical fashion can likewise be clamped in drill chucks having three chuck jaws. In addition, the tool is to have the limited axial mobility required when hammer drilling or chiselling. For this purpose, the device is equipped with three rotary driving elements arranged in a location hole and projecting inwards. The rotary driving elements are arranged in rotationally symmetrical fashion, are of equal width and have flanks which extend approximately parallel to one another. One of the rotary driving elements is longer in the radial direction than the other two in order to guarantee positionally correct insertion of the tool and satisfactory locking of a locking body in a closed groove of the tool. The rotary driving elements are fixed immovably in the location hole. A blocking element is arranged at least at one side wall of the open groove and narrows its otherwise free cross-section.
