Abstract
A pipe shears includes a base, a ratchet plate pivotally connected to the base, a cutter blade detachably mounted to the ratchet plate, a positioning member mounted between an elongated hole of the ratchet plate and a positioning groove of the cutter blade, and a push rod inserted in the base and stopped against a stop member. When the push rod is not pushed, it is positioned in the elongated hole of the ratchet plate and stopped against the positioning member to force the positioning member into engagement with the positioning groove of the cutter blade, and the cutter blade is not detachable at this time. When the push rod is pushed, the stop member is moved out of the elongated hole of the ratchet plate to unlock the positioning member from the positioning groove of the cutter blade for allowing removal of the cutter blade.
