Disclosed herein is a massaging device having a massage head capable of moving gradually away or approaching synchronously, comprising: a reversing device located at the center, a traversing device separately disposed on both sides of the reversing device, a power massage device provided on each traversing device characterized in that a touch switch is provided at the path end of one traversing screw of the traversing device when the touch switch is touched it may suspend the movement of the traversing screw in the original direction until both touch switches are touched to act together for synchronization a one-way bearing is mounted on the gear that drives the traversing device, so that its motor, in reverse or forward rotation, can control the massaging device to perform sentinel massage or mobile massage. The reversing device comprises a bump corresponding to a curved groove, for controlling the minimum angle and maximum angle within the curved groove, with a plurality of gear grooves corresponding to a spring thimble, and using a plurality of gear grooves to provide a variety of angle adjustments.一種同步漸遠向或漸近向移動按摩頭之按摩器,係包含有:一轉折裝置設於中間,轉折裝置兩旁分別設一橫移裝置,每一橫移裝置上設一動力按摩裝置;主要在於,橫移裝置之一橫移螺桿行程末端設一觸控開關,觸控開關被觸動時得暫停該方向橫移螺桿動作,待兩個觸控開關均被觸動才一起動作,以求同步;一單向軸承裝在傳動橫移裝置的齒輪上,使其馬達正反轉可控制按摩裝置係定點按摩或移動按摩,轉折裝置包括一凸塊對應一弧形槽,以該弧形槽範圍控制轉折最小角度與最大角度,以數齒槽對應一彈簧頂針,藉由多個齒槽提供多種角度調整定位。1‧‧‧按摩器14‧‧‧彈簧頂針20‧‧‧第一橫移裝置21‧‧‧第一橫移螺桿23‧‧‧第二斜齒輪24‧‧‧第一基座30‧‧‧第二橫移裝置31‧‧‧第二橫移螺桿33‧‧‧第二斜齒輪34‧‧‧第二基座40‧‧‧第一動力按摩裝置50‧‧‧第二動力按摩裝置71‧‧‧軟質連接帶72‧‧‧握柄80‧‧‧伸縮防塵保護套
