The present invention relates to a traction type rehabilitation device, which provides a traction stroke for significantly increasing arm stretching to achieve the effect and function of effectively stretching the physique, and comprises a hanging rack, a reciprocating driving module, and two holding members for pulling by hands. The hanging rack is wound with two ropes. The reciprocating driving module is disposed on the hanging rack, and comprises an activating member and a reciprocating driving unit for driving the activating member for reciprocating movement. Each of the holding members are respectively connected with one end of the rope and suspended below the hanging rack. The other end of each of the ropes is respectively connected with the activating member, such that each holding member may be dragged by the rope to make each holding member move with the activating member in an alternate and up-and-down reciprocating manner, thereby providing the patients hand with large-range reciprocating stretching exercise to overcome the limitation of conventional tracking stroke by the swinging amplitude of stepping crank. When using the rehabilitation machine, the reciprocating tracking stroke may be flexibly adjusted based on patients needs, so as to enhance the operational convenience and the practicability of rehabilitation effect.本發明係一種牽引式復健裝置,主要係提供可大幅增加手臂拉伸之牽引行程,進而達成有效伸展筋骨之功效及作用,包括一吊架、一往復驅動模組及二可供手拉的握持件,該吊架上繞設有二繩索,該往復驅動模組設於吊架上,且往復驅動模組包含有一引動件,以及一可驅動該引動件往復移動的往復驅動單元,各握持件分別連接繩索一端且懸掛於吊架下方,且各繩索另一端分別連接引動件,俾使各握持件分別經由繩索牽引使各握持件隨著引動件上下交替往復移動,藉此提供病人手部向上做出大幅度的往復拉伸運動,以克服習知牽引行程受限於腳踏曲柄擺動幅度之缺失,於使用復健機時,可根據病人需要靈活調整往復牽引行程,進而提升操作上之便利性,以及復健功效上之實用性。1‧‧‧吊架101‧‧‧立柱102‧‧‧橫稈11‧‧‧第一上滑輪12‧‧‧第二上滑輪13‧‧‧第一下滑輪14‧‧‧第三上滑輪15‧‧‧第四上滑輪16‧‧‧上承板17‧‧‧下承板18‧‧‧滑軌19‧‧‧齒條191‧‧‧齒輪192‧‧‧圓舵2‧‧‧第一繩索21‧‧‧第一握持件22、32‧‧‧配重塊3‧‧‧第二繩索31‧‧‧第二握持件4‧‧‧往復驅動模組41‧‧‧第一齒輪42‧‧‧第二齒輪43‧‧‧導引器431‧‧‧導桿44‧‧‧鍊條46‧‧‧引動件471‧‧‧第一萬向接頭472‧‧‧第二萬向接頭473‧‧‧連結件5‧‧‧座椅50‧‧‧椅背51‧‧‧轉軸52‧‧‧滑軌7‧‧‧底座71‧‧‧滾輪
