摘要

Fixing mechanism for tongs having a first and a second tong parts (11, 12) comprises an opening in the second tong part, a cylindrical click-and-pawl mechanism (15), a ratchet (124) on the periphery inside a hole in the first tong part in which the click-and-pawl mechanism is arranged, a hinge (13) for coupling the tong parts, an elastic part placed on the hinge, a fixing part loaded by the elastic part and a torsion spring (3) fixed to the tong parts. Preferred Features: The toothed part of the click-and-pawl mechanism has a helical gearing and the toothed part of the hinge has a corresponding helical gearing.
