The adaptor includes a ladder stand base support which is attachable to the base of a tree and which receives the lower end of the ladder stand. A speed lock assembly is part of the upright adaptor and is attachable to an upper portion of the ladder tree stand. It includes a self-tapping screw and a double-acting ratchet wrench which is operable by a person standing on the ground once the ladder tree stand has been erected.
