ABSTRACT:
In a hand-held motor-driven compass saw, the end of the reciprocating rod is connected to the end of the saw blade by means of a clamping member. The reciprocating rod has a U-shaped cross-section whereby it defines a relatively flat recess into which the end of the saw blade is inserted. The end of the reciprocating rod and the end of the saw blade are surrounded by a protective shield. The clamping member may be displaced along the end portion of the reciprocating rod from outside of the shield so as to release the clamping member or to lock it on the end of the reciprocating member when the saw blade is inserted into the recess formed in the U-shaped reciprocating rod.
