<p>PURPOSE: A jig for a torsion spring is provided to prevent a torsion spring from bouncing off in the operation by mounting an extension unit on a first and a second mounting hole. CONSTITUTION: A jig for a torsion spring comprises a first and a second operation bar(10,20), a mounting bracket(30), and a stopper(40). A first and a second mounting hole are formed on the first and the second fixing unit of the tip-end part of the first and the second operation bar. The end part of the torsion spring is settled in first and second seating groove. The first and a second fixing unit are selectively fixed among the first and a second operation bar to one. The mounting bracket establishes an angle entry value of the fixing units. The stopper is fixed and coupled with the first and second operation bars through an adjustment slot(32) of the mounting bracket.</p> |
