<P>PROBLEM TO BE SOLVED: To provide tweezers allowing a holding part angle to be changed even before a holding object is gripped and even in a state of gripping the object, and allowing the angle itself to be instantly changed to an optional value. <P>SOLUTION: These holding-part-angle changeable tweezers are composed by dividedly forming each holding part 4 and each gripping part 2, rotatably connecting both the parts to each other, and normally bringing a formed angle into a linear state. In the holding-part-angle changeable tweezers, a semilunar pushing plate 14 is attached to a root 13' of a bifurcated fitting made of a plate spring formed in a nearly-V-shape or nearly-U-shape form and having an elastic function by sticking one of two spring plates for changing the angle of the holding part 4 or bending one spring plate; both tips of the one-side spring plate are directly connected to the roots of the respective holding parts 4 forming a pair to arrange an angle changing operation plate 15 capable of following the opening/closing operation of the gripping parts 2 and guiding the angle changing operation of the holding parts 4; and the angle of the holding parts 4 can be freely changed by an index finger operation even before a holding object is gripped and even in a state gripping the object. <P>COPYRIGHT: (C)2013,JPO&INPIT |
