发明名称 Pivotal hand tool with flexural pivot joint and method of assembling same
摘要 A hand tool includes first and second lever members which intersect and have aligned openings therethrough in which is received a flexural pivot assembly, including a pair of cylindrical members respectively disposed in the lever member openings and respectively fixed to the lever members for movement therewith. In one embodiment the cylindrical members of the pivot assembly are press fitted directly in the openings of the lever members. In another embodiment, bushings are press-fitted in the openings between the lever members and the cylindrical members. A spacer is disposed between the cylindrical members to prevent their axial movement toward each other, and the spacer may extend between the lever members and has a very low coefficient friction so as not to impede pivotal movement of the levers.
