发明名称 Adrin leverage ratchet
摘要 A standard mechanic's ratchet modified with a square-receiving hole at the bottom of the handle receives the square drive of a second ratchet to provide additional leverage for the removal of nuts and bolts. Existing mechanics ratchets do not have a hole to accept the square drive of a second ratchet. The Adrin Leverage Ratchet provides mechanics with additional leverage for the removal of over-tightened nuts and bolts.
