摘要：An improved blade guard stop for a circular saw. The circular saw includes a sawblade driven by a motor for rotation about an axis, a blade guard rotatable about the axisbetween a covered position, in which the saw blade is covered, and an uncovered position,in which the saw blade is exposed, a biasing member biasing the blade guard toward thecovered position, and a flexible spring member to absorb the rotational force of theblade guard and to absorb the biasing force of said biasing member. In the preferredembodiment, the spring member is a leaf spring. Additionally, the circular saw includes anadjustable shoe plate which changes the direction of impact of the blade guard on thespring member. The spring member absorbs the rotational force each adjusted direction.Also, the spring member and the blade guard are constructed of low friction materials sothat movement of the blade guard against the spring member does not impedeadjustment of the shoe plate of the circular saw.
