Portable power saw has a swing feeler through the machine housing slit, next to and parallel to the circular sawblade plane, to register the workpiece thickness and stop the tool when the blade has cut through the material

摘要

The portable powered circular saw has a machine housing (10) with a rotating sawblade (12) through a passage slit (16). A swing feeler (24) extends through the slit next to the sawblade, and parallel to its plane, to register the thickness of the workpiece (23) to be sawn. It is on a swing axis (241) parallel to the sawblade shaft axis (131). The gap between the feeler pin (26) and the swing axis is equal to the outer radius of the sawblade.
