Abstract: 一种活塞驱动机构及筋膜枪，活塞驱动机构（20）包括：驱动支架（21）、连接驱动支架（21）的驱动电机（22）、安装在驱动支架（21）上的齿轮组件（23）、活动设置在驱动支架（21）附近的传动活塞（24）、连接传动活塞（24）的第一连杆（25）、及连接传动活塞（24）的第二连杆（26）；齿轮组件（23）包括转动设置在驱动支架（21）上的第一齿轮片（231）、转动设置在是驱动支架（21）上的第二齿轮片（232）、及安装在驱动电机（22）转轴上的驱动齿轮片（233）；驱动齿轮片（233）直接或间接驱动第一齿轮片（231）及第二齿轮片（232）同时转动；在平行第一连杆（25）或第二连杆（26）的活动范围的平面上，第一连杆（25）与第二连杆（26）从相反的方向同时靠近或同时远离传动活塞（24）的轴线摆动。该活塞驱动机构有效抵消了侧向力，避免传动活塞在直线运动的垂直方向上产生了晃动，提高筋膜枪的使用体验。

Abstract: A portable cardiac massage apparatus (1) comprises a C- shaped frame (2) including a base (3) for positioning under the back of a supine patient, an upper arm (4) and an upright body (5) which interconnects the base (3) and the upper arm (4), a plunger (6) for applying pressure to the sternum of a patient lying on the base (3), which plunger (6) is coupled to the upper arm (4) and movable with respect to the upper arm (4) in a direction from the upper arm (4) to the base (3) and back and a lever (9) for operating the plunger (6) which lever (9) is pivotally coupled to the plunger (6) through a first hinge (10) and to a link rod (20) through a second hinge (21) located at a distance from the first hinge (10). The link rod (20) is pivotally coupled to the upper arm (4) through a third hinge (22) located at a distance from the second hinge (21). The lever (9) is also pivotally connected to an auxiliary rod (23) through a fourth hinge (24) located at a distance from the first and second hinges (10, 21). The auxiliary rod (23) is pivotally connected to the upright body (5) through a fifth hinge (25) that is displaceable along the upright body (5) through a guide (26) at the upright body (5) in a direction from the upper arm (4) to the base (3) and back. The first hinge (10) is located between the second and fourth hinges (21, 24) and beyond the fourth hinge (24) as seen in a direction from the upright body (5) to the plunger (6).
