Claim Text:
1. Pliers comprising: a pair of arm members; a pair of handles connected to each other for movement of the arm members towards and away from each other; at least one seat body secured in a receiving room of one of the arm members and defining a through hole in a direction substantially vertical to the arm member; at least one working jaw detachably engaged with the seat body to be supported in the receiving room of the arm member, and defining in a side thereof an indentation to be communicated with the through hole of the seat body; and at least one control assembly including a knob disposed in an opening of the through hole of the seat body, and a positioning pin having a free end passing through the through hole of the seat body and an opposite end secured to an inner side of the knob; wherein the knob and the seat body are arranged in a manner that rotation of the knob displaces the knob axially with respect to the seat body, causing the positioning pin to move between a locking position where the free end of the positioning pin is engaged in the indentation of the working jaw to stop the working jaw from departing from the seat body, and a releasing position where the free end of the positioning pin is removed from the indentation of the working jaw to allow detachment of the working jaw from the seat body.
