This invention provides a manual driven rocking bar which is a mechanism capable of performing forward or backward drive by either forward or backward rotation to facilitate long distance operation for wheelchairs and water buoys. Also provided is an electrical transmission mechanism disposed for the purpose of long distance operation and useful in conjunction with the manual driven mechanism to operate in a synergistic or independent manner to provide multiple choices to users. In particular, when the electrical transmission mechanism is failed and manual driving is the only choice, the electrical transmission mechanism is not affected by the magnetic attraction influence of motor, thereby overcoming the long-existing drawbacks of electric vehicles. Undoubtedly, electric-assisted manual wheelchairs are also included to make the wheelchairs suitable for various terrains.本創作提供一種以人力驅動搖桿,無論正反轉都能前進驅動或後退驅動之機構,以利於輪椅或水上浮體長距離之運作;以及一種為長距離運行而增設,與人力驅動機構配合,可相互輔助,或相互不影響之電動傳動機構,讓操控者多種選擇;尤其在電動驅動機構故障,人力驅動方式為唯一選擇時,不受馬達之磁吸效應影響,改善電動車輛一直存在之缺點,當然也包含電動輔助手動輪椅,使輪椅能適於各種地形。10‧‧‧第一驅動輪11‧‧‧第二驅動輪12‧‧‧第一從動輪13‧‧‧第二從動輪14‧‧‧傳動件15‧‧‧搖桿16‧‧‧驅動輪固定軸17‧‧‧從動輪固定軸20‧‧‧第一棘齒環21‧‧‧第二棘齒環22‧‧‧棘爪裝設環23‧‧‧第一正棘爪23-1‧‧‧第一正連接件24‧‧‧第二反棘爪24-1‧‧‧第二反連接件25‧‧‧第一反棘爪25-1‧‧‧第一反連接件26‧‧‧第二正棘爪26-1‧‧‧第二正連接件30‧‧‧棘爪固定座30-1‧‧‧下插銷作動孔30-2‧‧‧棘爪突出孔31‧‧‧棘爪31-1‧‧‧棘爪下孔31-2‧‧‧棘爪上孔31-3‧‧‧下插銷31-4‧‧‧上插銷32‧‧‧彈性物33‧‧‧車輪34‧‧‧車架35‧‧‧切換器36‧‧‧棘爪操控器36-1‧‧‧上插銷作動孔36-2‧‧‧連接物固定36-3‧‧‧連接物
