Abstract
The present disclosure generally relates to quick change attachments for a pneumatic percussive tool. The attachments convert a pneumatic percussive tool, such as an air impact tool with proximal attachment means, which has a “pushing” force, into a pneumatic percussive tool having a “pulling” force. Once attached to the pneumatic percussive tool, the attachments also provide a quick change feature for allowing “pulling” tools to be simply and easily removed and replaced.
Claims19
A pneumatic percussive tool comprising:
- a tool body having a hollow interior with a distal end and a proximal end;
- a piston slideable in the hollow interior between the distal end and the proximal;
- a first attachment coupler positioned on the distal end of the tool body for converting the tool to a pulling tool;
- an opening positioned at the distal end of the tool adjacent the first attachment coupler in communication with the hollow interior;
- a second attachment coupler positioned on the proximal end of the tool body configured to attach a pulling tool;
- and
- a removable end cap configured to selectively attach to the first attachment coupler and seal the opening and regulate air pressure within the internal cavity, the removable end cap configured to not protrude into the opening or into the hollow interior of the tool.
