摘要

The clamp for an electrical reciprocating saw blade has a clip (1) with two side walls (11), defining a space between them, with a blade mounting pin between the side walls. Two clamping blocks (2) can swing between the side walls, each with a toothed zone (23) to lock springs (5) between the walls and the blocks. A covering plate (3) with a passage opening (31) is on the clip. A knob (4) with a pin (40) is passed through the cover passage opening, with a tooth slit (41) to engage the toothed zones on the outer surfaces of the blocks.
