摘要：A replaceable spindle locking system for a power tool enables an operator toreplace a lock member without disassembling the tool. An externally-accessible retainingmember, such as a washer, is trapped between a ledge located in a housing recess and ashoulder formed on the lock member, which is normally spring-biased out of
engagement with a driven member. The coaction of these elements simultaneously andreleasably normally retains both the lock member and the retaining member connectedto the housing. When it is desired to replace the lock member, the operator depressesthe lock member against the urging of the spring until the lock member is out of
retaining engagement with the retaining member. Then the retaining member is slideablymoved out of engagement with the lock member, thereby allowing the operator toquickly remove it.
