ABSTRACT:
A pipe wrench includes a first elongated member and a second elongated member. A first intermediate section of the first elongated member includes a recess defined in an inner side thereof that faces a second intermediate section of the second elongated member. A bottom wall that defines the recess has a ridge formed thereon. A first stepped portion and a second stepped portion are formed on two sides of the recess, respectively. A first pin and a second pin are respectively formed on the first stepped portion and the second stepped portion. The second intermediate section includes a number of parallel channels defined in an inner side thereof that faces the first intermediate section. The ridge is releasably engaged with one of the channels. A panel is mounted to an outer side of second intermediate section and includes two holes through which the first pin and the second pin are extended and riveted, respectively. The panel is securely engaged with the first intermediate section of the first elongated member to enclose the second intermediate section of the second elongated member. The panel includes two resilient blocks that exert a force to bias the second intermediate section toward the first intermediate section such that the first intermediate section and the second intermediate section closely contact with each other to thereby provide a reliable grasping effect.
