Title: Lifting jack

Abstract: A lifting jack includes a lifting mechanism pivoted to a base and a support bracket member so as to lift or lower the support bracket member relative to the base, a driving shaft journalled on a right link pin to be rotated so as to move a left link pin relative to the right link pin, a reflecting member hinged to the base so as to enable the reflecting member to be displaced from a folded position to an unfolded position and to be disposed to reflect images of an object lifted by the support bracket member. Preferably, a lighting device is disposed to illuminate a desired area of the object. Two limit switches are disposed to prevent excess movement of the bracket support member.
