- 2. The ratchet wrench of claim 1 wherein one of said multiple pins is a pivot pin, said pivot pin being positioned at a first end of said central plate and having a first length.
- 3. The ratchet wrench of claim 2 wherein a second of said multiple pins is a locking pin, said locking pin being spaced from said pivot pin and having a second length.
- 4. The ratchet wrench of claim 1 wherein said activating shaft is positioned at a second end of said central plate and has a third length.
- 5. The ratchet wrench of claim 2 wherein a second of said multiple pins is a locking pin, said locking pin being spaced from said pivot pin and having a first length.
- 6. The ratchet of claim 4 wherein said third length is greater than the distance between first side and said second side of said receiving area.
- 7. The ratchet of claim 6 further comprising a resistance system, said resistance system being affixed to said activating shaft proximate said receiving area second side, said resistance system maintaining said central plate adjacent to said receiving area.
- 8. The ratchet of claim 7 where depression of said resistance system to a first point removes at least one of said multiple pins from said ratchet head flange channels.
- 9. The ratchet of claim 8 wherein depression of said resistance system to a second point removes all of said multiple pins from said ratchet head flange channels.
- 10. The ratchet of claim 1 further comprising a release member and wherein said activating shaft is notched to create a stop along a length of said shaft, said release member interacting with said stop to prevent depression of said activating shaft without removal of said release member.
- 11. The ratchet of claim 10 wherein said release member is a pin extending into said receiving area and a spring on the exterior of said release member.
- 12. The ratchet of claim 10 wherein said release member is a ball nose spring plunger pin, said ball nose coming in contact with said activating shaft stop when said activating shaft is depressed at a first pressure and said ball nose withdrawing into said plunger pin at a second pressure to enable said activating shaft to depress fully.
- 13. The ratchet of claim 1 wherein said ratchet head flange has a first end, a second end and a width, said second end being contiguous with said ratchet head and said first end having multiple holes along said width, said multiple holes being dimensioned to receive said locking pin, and a pivot hole, said pivot hole being centered within said flange proximate said second end and dimensioned to receive said pivot pin.
- 14. The ratchet of claim 13 wherein further comprising a recessed channel along said width, said multiple holes being within said recessed channel.
- 15. A ratchet wrench having a removable ratchet head, said wrench having:a body, said body having a handle and a receiving area, said receiving area having a first side; a second side, said second side being parallel to said first side; a receiving notch, said receiving notch being between said first side and said second side and having an open end and a closed end; multiple channels, at least one of said channels extending from said first side, through said notch, to said second side; at least one activating shaft channel, said activating shaft channel extending from said first side to said second side, through said receiving area proximate said receiving notch closed end; a release device, said release device having a central plate, a pivot pin, said pivot pin being at right angles to said central plate, said pivot pin being attached to and extending dimensioned to align with and fit within one of said multiple channels; a locking pin, said locking pin being attached to and extending at right angles to said central plate and spaced from said pivot pin, said locking pin being dimensioned to align with and fit within one of said multiple channels at least one activating shaft, said at least one activating shaft being at right angles to said central plate, said activating shaft being dimensioned to align with and fit within said activating shaft channel and have a length greater than the distance between first side and said second side of said receiving area; a resistance system, said resistance system being affixed to said activating shaft proximate said receiving area second side, said resistance system maintaining said central plate adjacent to said receiving area and depression of said resistance system to a first point removes said locking pin from said ratchet head flange channels and depression of said resistance system to a second point removes said locking pin and said pivot pin from said ratchet head flange channels; a ratchet head, said ratchet head having a flange, said flange being dimensioned to fit within said receiving notch and having multiple channels, each of said multiple channels being aligned to receive said multiple pins, said ratchet head flange having a first end, a second end and a width, said second end being contiguous with said ratchet head and said first end having multiple holes along said width, said multiple holes being dimensioned to receive said locking pin, and a pivot hole, said pivot hole being centered within said flange proximate said second end and dimensioned to receive said pivot pin; wherein said multiple pins are inserted into said multiple channels place said release device proximate said first side of said receiving area to maintain said ratchet head flange securely within said receiving notch.
- 16. The ratchet of claim 15 further comprising a release member and wherein said activating shaft is notched to create a stop along a length of said shaft, said release member interacting with said stop to prevent depression of said activating shaft without removal of said release member, said release member being a pin extending into said receiving area and a spring on the exterior of said release member.
- 17. The ratchet of claim 15 further comprising a release member and wherein said activating shaft is notched to create a stop along a length of said shaft, said release member interacting with said stop to prevent depression of said activating shaft without removal of said release member, said release member being a ball nose spring plunger pin, said ball nose coming in contact with said activating shaft stop when said activating shaft is depressed at a first pressure and said ball nose withdrawing into said plunger pin at a second pressure to enable said activating shaft to depress fully.
