A kind of hand pushing device, be suitable for being mounted on one can what sit always on the wheelchair changed between state and an oblique seat state. The hand pushing device includes an assembly, a handle unit and an engaging member. The assembly extends up and down and group connect the what wheelchair about one chair back pipe extended upper end. The handle unit there is about one to extend and be socketed the connecting piece and can the Coupling of opposite connecting piece rotation and the handle part of the consubstantiality connection Coupling. The handle part is bent with respect to the Coupling to be extended, and can the what wheelchair be converted into the oblique seat state and when the Coupling is with respect to assembly rotation, be driven and change highly. Change height by that can be driven under the what handle part what oblique seat state, more promotion force selections can be provided, therefore have the advantages that sharp what pushes the wheelchair.一種推手裝置,適用於安裝在一個能於一直坐狀態及一斜坐狀態間變化的輪椅上。該推手裝置包含一個組裝件、一個握把單元,以及一個結合件。該組裝件上下延伸並組接於該輪椅的一根上下延伸的椅背管的上端部。該握把單元具有一個上下延伸且套接該組接件而能相對該組接件轉動的套接件,以及一個同體連接該套接件的握把件。該握把件相對該套接件彎曲延伸,並能於該輪椅變換至該斜坐狀態且該套接件相對該組裝件轉動時,被帶動而改變高度。由於該握把件於該斜坐狀態下能被帶動而改變高度,能提供更多的推動施力選擇,故具有利於推動該輪椅的優點。251‧‧‧椅背管3‧‧‧組裝件31‧‧‧組裝段32‧‧‧組接段321‧‧‧凹槽322‧‧‧貫孔323‧‧‧插孔4‧‧‧握把單元41‧‧‧套接件42‧‧‧握把件421‧‧‧第二穿孔43‧‧‧套接部431‧‧‧第一側緣432‧‧‧第二側緣433‧‧‧第一邊緣434‧‧‧第二邊緣435‧‧‧貫通口436‧‧‧卡槽組437‧‧‧卡嵌槽44‧‧‧組插部441‧‧‧第一穿孔51‧‧‧結合件52‧‧‧定位柱53‧‧‧穿設柱54‧‧‧彈性件D1‧‧‧前後方向D2‧‧‧左右方向
