ABSTRACT:
The manual pipe bender has a stationary handle, a head, a bending die, a bending lever, and a bending handle. The stationary handle has a distal end, and the head is attached to the stationary handle. The bending die has a bending surface and multiple ratchet teeth. The bending lever attaches the bending die rotatably to the head. The bending handle is attached to and rotates the bending die around the head and has a drive bracket that engages a selected ratchet tooth on the bending die to keep the handles from crossing. Consequently, bending acute angles in pipes is convenient.
