ABSTRACT:
A wire cutter includes a fixed handle having an enlarged top end and a movable handle which has a top end pivoted to the enlarged top end and a gear unit stationarily provided on the top end. An elongated plate has a first end to which the gear unit is pivoted and a second end. A gear member is pivoted to the second end and meshes with the gear unit. A fixed cutting member includes a lower mounting portion fixed to the enlarged top end and an upper curved cutting portion. A curved movable cutting member is pivoted to the cutting portion and has one side formed with a toothed section. An extension spring is connected to the first end of the plate and the movable handle and biases the plate so that the plate inclines upwardly to permit engagement between the toothed section and the gear member. A pawl member is resiliently pivoted to the enlarged top end adjacent the gear member opposite to the gear unit. The pawl member normally engages the toothed section and permits movement of the movable cutting member toward the fixed cutting member.
