    摘要: In a portable circular saw depth of cut adjustment is effected by pivoting movement between a shoe 24 (which supports the saw on a workpiece) and a motor and gear case housing 26 (carrying the saw blade 12) about a pivot connection 28 rearward of the motor and gear case housing. Forward of the housing 26 an upwardly extending arcuate depth slide 38, fixed to the shoe 24, slidably engages an arcuate depth guide 40 carried by the motor and gear case housing 26. Towards the upper end of the depth slide 38, and in generally fixed relation to it, a clamping assembly 42 selectively clamps the depth slide 38 and depth guide 40 together to establish a depth of cut adjustment setting. The essentially fixed relationship of the locking knob 100 of the clamping assembly 42 to the shoe 24 mean that the operations of changing depth adjustment setting may be made without changing operator's hand positions on the saw. In addition, the fixed position of the knob 100 in sawing operations mean that by design, suitably shaped, sized and positioned, it may be used as an auxiliary handle in guiding the saw in operations.
