Abstract
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.

A tool holder (2) for an electrically powered hammer comprising:
- a tube-like tool holder body (66) which can be fitted to or formed at 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 member (52) which extends around 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;
- wherein the locking member (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.
