The casing includes two connecting parts, each having a rail, an opening, and a cutout. The holder includes two accommodation grooves, each being arranged on each of two side surfaces of the holder. The push knob is adapted to drive the holder. The positioning member includes a rotary stem and a protrusion. The two switch buttons are mounted in two cutouts of the two connecting parts, and each switch button has a pressing tab extending out of each cutout from an outer wall thereof and its inner wall abuts against each of two side surfaces of the positioning member. Each switch button also has a fixing rib arranged on an inner surface thereof to retain with one of two blades which does not engage with the protrusion.

Abstract: Pliers for C-shaped lock rings include a holding unit and a clamping unit. The holding unit is composed of two handles and a control portion. The clamping unit comprises two identical clamping members and a positioning disk. When the control portion is released to engage with the positioning slot to lock the handle; when the control portion is pushed to disengage with the positioning slot, the handle rotate around the center shaft corresponding to the rotations of the clamping unit, such that the clamping members can be open or closed.
