An improved structure of a specimen collector, including: a body provided with an accommodating space and an open opening at the upper end thereof； an upper cover provided at the upper end of the body, an inner concave portion provided at the lower end and having a lower opening, the upper cover An inset hole is provided in the center of the upper end and an edge portion is formed on the inner side； an elastic body is provided on the upper cover, which includes a lower seat and an upper stage connected to each other, a concave ring is provided between the lower seat and the upper stage, and the lower seat is provided with In the inner concave portion of the upper cover, the upper platform protrudes from the upper end of the insertion hole of the upper cover, and the concave ring of the elastic body is embedded in the edge portion of the upper cover； the upper end of the upper platform may be flat or provided with At least one puncture slot. In this way, the structure can be simplified, the injection liquid can be directly punctured into the closed body through the puncture part of the syringe and soaked with the specimen, and the injection liquid can be adjusted at any time according to the needs, which effectively improves the convenience of use, saves time and effort and reduces costs.一種檢體採集器改良結構，包括︰一本體，其設有一容置空間且於其上端呈開放之開口；一上蓋，設於該本體上端，其下端設有一內凹部且具有一下開口，該上蓋上端中央設有一嵌孔且內側形成一緣部；一彈性體，設於該上蓋，其包含有相互連接之一下座及一上台，該下座及該上台間設有一凹環，該下座設於該上蓋之該內凹部，該上台凸出設於該上蓋之該嵌孔上端，該彈性體之該凹環係嵌設於該上蓋之該緣部；該上台上端係可呈平面或設有至少一穿刺縫槽。藉此，能簡化結構，透過注射器之穿刺部，直接穿刺注入藥液進入封閉本體且與檢體浸泡，可依據需要隨時調整注入藥液，有效提升使用方便性，省時省力且降低成本。
