This creation is a kind of height measuring gauge,Comprising an ontology and a distance measuring device,Wherein the ontology include a clamping piece,One stop part and an articulated part,Wherein the clamping piece by the first side wall,The second sidewall and the third side wall group set and are surrounded by a holding tank,And the first side wall has one first engaging portion,The stop part has a first pivoting portion,The articulated part system is pivotally connected the stop part what the first side wall,And include an abutting part,One second pivoting portion and one second engaging portion,When the articulated part is moved to a packing position,The abutting part system abuts the stop part simultaneously the packing stop part and the clamping piece,The distance measuring device system sets the what ontology； Thereby,This creation can clamp the various door body of what and cylinder moves freely,And the stop part of arranging in pairs or groups,The Combination Design of the articulated part and distance measuring device three,Also can more acurrate measurement height,And volume reduction more has characteristic easy to carry.本創作為一種身高測量器，包含一本體及一光學測距器，其中該本體包含一夾持件、一止擋件及一樞接件，其中該夾持件係由該第一側壁、該第二側壁及該第三側壁組設並圍繞成一夾持槽，且該第一側壁具有一第一結合部，該止擋件具有一第一樞接部，該樞接件係樞接該止擋件於該第一側壁，且包含一抵接部、一第二樞接部及一第二結合部，當該樞接件移動至一迫緊位置時，該抵接部係抵接該止擋件並迫緊該止擋件與該夾持件，該光學測距器係設於該本體；藉此，本創作可夾持於各式門體及柱體自由移動，且搭配該止擋件、該樞接件及該光學測距器三者之組合設計，亦能更準確量測身高，而體積減少更有攜帶方便之特性。
