Reciprocal force outputting mechanism

A reciprocal force outputting mechanism comprising:

• a body conjoined to an actuating device;
• the body has a slide slot that contains a slide block, thereby providing for a reciprocal movement of the slide block along the interior edges of the slide slot;
• the slide block has an elongated opening formed centrally and a row of teeth are disposed along each of the two facing sides of the elongated opening;
• a stem extending from one end of the slide block is inserted through a guide hole of the body;
• a power output shaft of the actuating device is inserted through a center hole of a gear and rotatably situated in a journal hole in an upper cover;
• the gear is secured onto the power output shaft, which enables the rotation of the gear;
• when the gear revolves and teeth of the gear are respectively enmeshed with said row of teeth, the slide block is brought into reciprocal motion, causing the reciprocal movement of the stem which serves as a means of outputting force;
• wherein the body consists of a base fastened to the upper cover;
• the base encloses the slide slot containing the slide block and the upper cover has a journal hole in which the power output shaft is rotatably situated;
• and
• wherein the actuating device consists of a pneumatic mechanism mounted on a lower cover, with the said pneumatic mechanism coupled to and rotating a gear train;
• the power output shaft of the gear train is inserted through the center hole of the gear;
• and a plurality of threaded support posts are inserted through a plurality of holes in the lower cover and fastened to a plurality of threaded holes in the base, enabling the attachment of the actuating device to the other side of the base.
