Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To prevent the unexpected release of a lock mechanism due to the strong pressure applied to a switch by fitting a switch inside of a handle freely to be turned around a first axis so as to operate a motor. SOLUTION: A latch 62 is positioned in a lock position or an engaging position, and a notch 68 is engaged with a lock pin 60 of a trigger 44, and maintained on the lock pin 60 by a compression spring 76. In case of trying to rotate the trigger 44, since the lock pin 60 and the notch 68 are engaged with each other, the latch 62 hinders the rotation. Force vector in the lock pin 60 is directed so as to be extended through a pivotal axis 64 of the latch. The force vector in case of trying to rotate the trigger 44 with the forefinger is generated in a tangent direction in relation to the radius of rotation, and the pivotal axis 64 of the latch 62 is extended so that a vector 92 obtained as a result of the operation of the trigger 44 passes through the pivotal axis 64.  Consequently, the only force directly passing through the pivotal axis 64 is applied to the latch 62, and the accidental release of the latch 62 can be prevented.
