ABSTRACT:
A ratchet-based adaptor assembly is comprised of a main body, a shell, a ratchet-like driven member, a switch member, and a spring. The shell is covered on the main body, having a neck formed at a side for connection with a wheel replacement wrench. A receiving space is defined between the main body and the shell. The ratchet-like driven member is rotatably mounted in the receiving space, having a plurality of teeth and an adaptor for connection with a rotatable joint of a jack. The switch member includes at least two teeth for engaging the teeth of the ratchet-based driven member, being pivotally mounted in the receiving space but having a part exposed outside the main body for poking by the user's hand. The spring is mounted in the receiving space so as to keep enabling the switch member to engage the driven member.
