Abstract:
1. A lifting jack comprising: a base which includes a bottom wall that is elongated in a longitudinal direction, and that has front and rear sides opposite to each other in a transverse direction relative to the longitudinal direction, and a mount wall unit that extends from both said front and rear sides in an upright direction and that has first and second pivoted areas opposite to each other in the longitudinal direction; a support bracket member which is spaced apart from said bottom wall in the upright direction, and which is movable towards and away from said bottom wall; a lifting mechanism pivoted to said first and second pivot areas and said support bracket member; a driving device which is mounted on said lifting mechanism and which is driven to move said lifting mechanism so as to move said support bracket member away from or towards said bottom wall, thereby placing said support bracket member in an uppermost or lowermost position; and a first reflecting member which has lower and upper sides opposite to each other, said lower side being hinged to one of said front and rear sides of said bottom wall about a first hinging axis in the longitudinal direction so as to enable said first reflecting member to be displaced from a folded position, where said upper side is closer to said mount wall unit, to an unfolded position, where said upper side is remote from said mount wall unit and is disposed to reflect images of an object lifted by said support bracket member.
