如图14至图16所示，其为往复式肌肉放松设备的第五具体实施例。
往复式肌肉放松设备包括壳体、能够做旋转运动的马达2、能够做直线往复运动的按摩头模组11及能够将该旋转运动转换为直线往复运动的动力转换机构。壳体包括机壳1及安装在机壳下部的手柄22。手柄22包括手柄外壳62及固定在手柄外壳顶部开口的旋转定位块63。机壳下部与手柄连接的部分是基座15。该基座下方固定有旋转轴座61，该旋转轴座61向下穿过旋转定位块63后用卡簧58固定，从而将手柄22悬挂机壳1的下方，且旋转定位块63通过该旋转轴座61与基座转动连接，旋转轴座61具有轴线，旋转定位块63能够绕着该轴线转动。
动力转换机构包括转动轮51、连杆52及连杆座53。转动轮51与马达轴固定，其能够绕主旋转轴线转动。连杆52的后部通过第一球铰76与转动轮51铰接，连杆52的前部通过第二球铰77与连杆座53铰接。第一球铰76的球心位于主旋转轴线之外，第二球铰77的球心也位于主旋转轴线之外。连杆座53与运动轴7固定，按摩头模组安装在运动轴7的前部。为了对运动轴7的转动运动进行约束，机壳内可以还可以固定有轴套8，轴套8具有沿第一轴线设置的直线轨道(如通孔)，运动轴7与该直线轨道配合，使运动轴能够带着按摩头模组沿第一轴线做直线往复运动。马达2工作时，连杆52与主旋转轴线的夹角变化，连杆52在沿主旋转轴线的方向上的长度变化，进而连杆52带着运动轴7做直线往复运动，通过按摩头模组实现对用户身体部位的捶打冲击。第一轴线可以与主旋转轴线重合或平行，较佳的是，第一轴线与主旋转轴线重合。
锁止机构包括驱动件14、止转件13及弹性件12。驱动件14具有旋转壳64和螺旋 块68，旋转壳64转动安装在机壳1的端面，从而能够相对机壳1绕第一轴线旋转，螺旋块68与旋转壳64固定，该螺旋块68具有螺旋槽。止转件13具有止转销70和卡销69，止转销70与卡销69垂直，卡销69能够与螺旋槽配合。弹性件12的一端与机壳1连接，另一端与旋转壳64连接。工作时，按照图15箭头所示方向转动旋转壳64，带动止转销70从旋转定位块63的止转槽72中退出来而实现解锁，进而可以转动手柄22，在该过程中，弹性件12被压缩。转动到位后松手，弹性件12恢复形变，使旋转壳64反向转动复位，进而通过螺旋槽将止转件的止转销70重新卡入旋转定位块的止转槽72。
