This creation system includes a receiving main body, a wheel body, a weight element, a pulling element, a plurality of receiving fool proof location structures and a plurality of drainage bottle fool proof location structures. Wheel body and weight element set what and accommodate bottom part body two sides, accommodate fool proof location structure and drainage bottle fool proof location structure system for accommodating main body and drainage bottle is installed positioning, have the liquid sealing pipe for protruding into liquid level in drainage bottle. It is by the position of the neighbouring wheel body of direction. When pulling traveling through pulling element that will accommodate main body tendency wheel body, liquid level is protruded into liquid sealing pipe holding； When with wheel body and weight element for accommodating body upright positioning, liquid sealing pipe still keeps protruding into liquid level. Therefore this case reach have many advantages, such as fool proof location structure can ensure that device positioning, can vertical orientation improves safety, tiltable pulls just what action and see-through inspection liquid level.本創作係包括一容納主體、一輪體、一配重元件、一拉動元件、複數個容納防呆定位結構及複數個引流瓶防呆定位結構。輪體及配重元件設於容納主體底部兩側，容納防呆定位結構及引流瓶防呆定位結構係供容納主體將引流瓶裝設定位，引流瓶內具有伸入液面之液封管。其被朝向鄰近輪體的位置。當透過拉動元件將容納主體傾向輪體而拉動行進，液封管保持伸入液面；當以輪體及配重元件供容納主體直立定位時，液封管仍保持伸入液面。故，本案達到具有防呆定位結構可確保裝置定位、可直立定位提高安全性、可傾斜拉動便於行動與可透視檢查液面高度等優點。
