Abstract
A power tool in the nature of an impact tool in which a quick release mechanism for retention, and selective quick release of an accessory is provided. The quick release mechanism is actuated by a release pin disposed beneath the surface of the tool so as to be out of harms way, and actuation of the quick release mechanism is achieved by digital depression of the pin which in turn releases a latch engaging the accessory, permitting its removal from the tool.
Claims3
In a powered impact tool having an anvil, and being adapted to drive an accessory such as a socket to perform work, a quick release mechanism for selectively securing and releasing the accessory from the tool comprising:
- an axial bore formed in said anvil;
- a rod in said bore, said rod being secured for limited movement in said bore;
- a transverse bore, said transverse bore intersecting said axial bore;
- a release pin, said release pin disposed in said transverse bore, and engaging said rod, said release pin being wholly within said anvil;
- a latch, said latch engaging said rod and being movable by said rod between a latched and unlatched position, said latch adapted to retain an accessory on said anvil in its latched position;
- a first spring, said first spring being disposed on said axial bore to normally bias said rod toward said release pin, whereby depression of said release pin moves said rod against the bias of said spring to permit said latch to move to said unlatched position, and release of said release pin causing said rod to be moved by said spring bias to lock said latch in its latched position.
