US Patent 12090618 Tool assembly

A tool assembly includes a handle having a first end and a second end, a pivotal shaft mounted in the first end of the handle, at least one implement having a proximal end and a distal end, and a position-limiting mechanism mounted in the handle. The implement may pivot between an unfolded position and a folded position. When the implement is in its unfolded position, the position-limiting mechanism can lock the implement in position. The position-limiting mechanism may be lifted so as to allow the replacement of the implement.
