US 7,003,888 B2 · Clamping arrangement for receiving a saw blade

Abstract

A saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

Dependent claims

A saw blade clamping arrangement for a power tool including a housing, a drive shaft mounted for longitudinal reciprocating motion relative to the housing along an axis, and a saw blade releasably interconnected with the drive shaft, the saw blade clamping arrangement comprising:

a support member for attachment to the drive shaft;
a control member carried by the support member, the control member movable in a direction substantially perpendicular to the axis between a first position and a second position;
a locking member operative for selectively engaging the saw blade with the drive shaft such that the saw blade and the drive shaft are operatively engaged when the control member is in the first position and the saw blade and the drive shaft are permitted to be operatively disengaged when the control member is in the second position;
and
an actuation member for attachment to the housing, the actuation member operative to move the control member from the first position to the second position.
