摘要： When connecting two elements that are moveable with respect to one another, some amount of clearance, i.e., spacing between the elements, is included to minimize friction between the elements. The present invention is directed to setting the clearance within a desired range, regardless of manufacturing tolerances of the two elements. In particular, the present invention is directed to power cutting tools wherein it is necessary to set the clearance between one or more reciprocating blades and a blade support member.
