Abstract
A reciprocating saw includes a saw blade that is connected to a hand held driver for reciprocating the saw blade to perform a cut. A bit holder and a blade holder is used to provide connection between the saw blade and the handle of the hand held driver. The bit holder includes connecting mechanism for connecting the bit holder to the hand held driver. The blade holder provides a connection between the saw blade and the bit holder. The blade holder includes a holder body and a hex-shaped shank extending rearwardly from the holder body. The shank further includes a first holding mechanism for coupling the holder to the bit holder at the rear end and a second holding mechanism for coupling the saw blade to the holder at the forward end.
Claims24
A reciprocating saw comprising:
- a hand held driver;
- a bit holder connected to the hand held driver;
- a saw blade;
- a blade holder for providing connection between the saw blade and the bit holder, the blade holder having a holder body adapted for providing connection to the saw blade at the forward end of the blade holder, and a shank extending rearwardly from the holder body for coupling the blade holder to the bit holder at the rear end, said bit holder having a locking mechanism for releasably engaging said shank and including an annular sleeve for disengaging said locking mechanism by axial movement thereof.
A reciprocating saw comprising:
- a hand held driver;
- a bit holder connected to the hand held driver;
- a saw blade;
- a blade holder for providing connection between the saw blade and the bit holder, the blade holder having a holder body adapted for providing connection to the saw blade at the forward end of the blade holder, and a shank extending rearwardly from the holder body for coupling the blade holder to the bit holder at the rear end;
- wherein the holder body includes:
- a cylinder for connecting the holder to the saw blade;
- and
