Abstract: A C-type pliers contains a body, two positioning members, and two working shafts. The body is comprises of two clamping handles pivoted together so as to form a pressing end and a working end, the two clamping handles have the two working shafts, and each clamping handle has a hole communicating with an orifice of the clamping handle. Each working shaft includes a recessed neck, and each positioning member includes a peg pivoted in the hole, and the peg has an arcuate fixing section driven by the peg which is rotated so as to insert into the orifice and to retain with the recessed neck of the each working shaft. The peg has a flat releasing section, such that when the peg is rotated so that the flat releasing section faces to the recessed neck of the each working shaft, the each working shaft is released from the peg.
