A kind of mechanical motion mechanism technical field according to the utility model embodiment is described below with reference to Fig. 1-Fig. 3, especially
It is to be related to a kind of speed change Double-action reciprocating motion.
According to a kind of speed change Double-action reciprocating motion of the utility model embodiment, including：It is casing 1, bearing 2, defeated
Enter axle 3, input shaft support base 4, eccentric gear 5, non-circular gear 6, crank 7, crank bearing 8 and piston mechanism 9.
As shown in figure 1, it is respectively lower box 1 (1) and upper box 1 (2), the upper box 1 that casing 1 is made up of two parts
(2) and lower box 1 (1) edge is machined with through hole, they are connected by bolt.The left and right sides of casing 1 is provided with bearing
