The invention relates to an elevator with an extending table board. The elevator comprises a base, a support platform, a support arm stand positioned between the base and the support platform, a driving mechanism for driving the support arm stand to unfold or fold in a relative manner, a fence rack around the support platform, and an extending platform arranged on the upper surface of the support platform in a manner of moving in the length or width direction of the support platform; the support platform is square-shaped; the fence rack comprises first fences and a second fence; the first fences are sequentially arranged on three sides of the periphery of the support platform in a surrounding manner; the second fence is arranged on the periphery of the extending platform in a surrounding manner; the first fences form a gap; the extending platform and the second fence can move towards the interior or exterior of the first fences from the gap and can form a closed fence area with the first fences. Under the premise of forming the fence area, the elevator extends the support platform, prevents the phenomenon that the elevator cannot work safely caused by positioning deviation, and is very convenient and practical.
