Inventor: ASANO TAMORU
IPC: B25B7/12
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To facilitate force application for both operation arms, clamp, especially, a thin object completely, and improve ease of operation. SOLUTION: An operation arm 4 is capable of taking a non-working position and an initial working position for an operation arm 3 with a jaw 2 and the operation arm 4 relatively-moving at a connection part 8. Opening the operation arm 4 for the jaw 2 becomes incapable at the non-working position. At the initial working position, the operation arm 4 is opened more for the jaw 2 than the non-working position, so that opening and closing of the operation arm 4 becomes capable for the jaw 2. The opening angle between both the operation arms 3, 4 becomes large even if the opening angle between both jaws 1, 2 is small in the working condition, thus it is possible to grip both the operation arms 3, 4 in such a condition as a hand is fully-opened.  By releasing the engagement of the locking claw part 24 of a regulating arm 5 supported at the operation arm 4 with the locking edge part 30 of the operation arm 3, the opening movement between both the operation arms 3, 4, and the opening movement between both the jaws 1, 2 are regulated, and only closing movement between them are allowed.
