< Topic >To put with the helical torsion spring it to be possible to do the open operation of the body, because the helical torsion spring is concealed between the putting bodies of pair, there are no times which are caught to the other component at the time of the opening and closing operation of the putting body of pair, become the disturbance, the putting job tool which can do putting job comfortably it offers.SolutionsPutting body 1.1 of opening and closing unrestricted pair opening and closing unrestrictedly the putting body of the axial sticking and pair open having the spring 3 for open motion which is operated due to pivot 2, it can use for the pivot the helical torsion spring M which the volume equipment is done in the putting job tool of the manual sharp-edged tool and the manual tool etc which become, as a spring for open motion, the helical torsion spring concealment interior is done in the enclosing space which consists of the crevice which was respectively formed to the opposed face of the putting body of pair, both destals of the helical torsion spring stopping are stuck in the putting body which opposes respectively.< Choice figure >Drawing 1【課題】ねじりコイルバネにより挟み体の開動作を行うことができ、ねじりコイルバネは一対の挟み体の間に隠蔽されているので、一対の挟み体の開閉動作に際し、他の部材に引掛かったり、邪魔になったりすることがなくなり、挟み作業を快適に行うことができる挟み作業具を提供する。【解決手段】開閉自在な一対の挟み体1・1が枢軸2により開閉自在に軸着され、一対の挟み体を開動作させる開動用バネ3を備えてなる手動利器や手動工具などの挟み作業具において、開動用バネとして枢軸に巻装されるねじりコイルバネMが用いられ、ねじりコイルバネは一対の挟み体の対向面にそれぞれ形成された凹部からなる収納空間部に隠蔽内装され、ねじりコイルバネの両端部はそれぞれ対向する挟み体に止着されている。【選択図】図1
