The invention is an improved Offset Head Ratchet Wrench. It allows the user to remove or interchange different size ratchet heads or tools quickly with the push of a button attached at the head of the activating shaft. This shaft can activate in three stages if it is operating an offset wrench. The activating shaft is attached to an E shaped structure, which is made up of an activating shaft, locking pin and pivot pin, all three being attached to a central plate. Stage one is when the activating shaft is in a partially depressed position. The locking pin releases the ratchet head for rotation only. Stage two is when the activating shaft is fully depressed, it releases the pivot pin, allowing the ratchet head to be easily and quickly removed or exchanged for another type of tool with a similarly designed head. |
