When the front power output shaft 38 moves up and down, the first end of the front swing arm 310 is driven to move up and down, at this time, the included angle between the front swing arm 310 and the front bar-shaped guide hole 21 changes, and the second end of the front swing arm 310 drives the front movable housing 12 to swing around the front rotating shaft 14.

When the rear power output shaft 39 moves up and down, acting force is applied to the edge of the first strip-shaped trepanning 313, so that the rear swing arm 311 and the first rear connecting rod 312 rotate around the first pin shaft 23; the first rear pin 314 at the second end of the first rear link 312 moves around the first pin 23, and the first rear pin 314 exerts a force on the edge of the strip-shaped first rear pin insertion hole 16 during the movement to drive the rear movable housing 13 to swing around the rear rotating shaft 15. When the rear swing arm 311 rotates around the first pin 23, the second rear link 317 also rotates around the first pin 23, the second rear pin 320 at the second end of the second rear link 317 moves around the first pin 23, the second rear pin 320 applies an acting force to the edge of the strip-shaped second rear pin jack 321 in the movement process to drive the third rear link 318 and the fourth rear link 319 to rotate around the second pin 24, the third rear pin 322 at the second end of the fourth rear link 319 moves around the second pin 24, and the third rear pin 322 applies an acting force to the edge of the strip-shaped third rear pin jack 18 in the movement process to drive the rear movable housing to move. The first rear plug pin jack 16 and the third rear plug pin jack 18 are disposed at different positions of the rear movable housing 13, in this case, the rear movable housing 13 is divided into two parts 131 and 132, the two parts 131 and 132 can relatively rotate with a small angle, the first rear plug pin jack 16 and the third rear plug pin jack 18 are disposed on the two parts 131 and 132, respectively, and the first rear plug pin 314 and the third rear plug pin 322 drive the two parts 131 and 132, respectively.

In the process of rotating the driving disc 34, when the driving disc rotates to the position where the arc-shaped rack 44 is meshed with the swing rod transmission gear 42 of the rib-turning bucket, the swing rod transmission gear 42 of the rib-turning bucket is driven to rotate, and at the moment, the swing rod 41 of the rib-turning bucket swings; when the free end of the tumbling oscillating bar 41 swings downwards around the tumbling oscillating bar positioning shaft 43, the front ends of the machine core box body 2 and the shell 1 are lifted, so that the rear end of the toy animal contacts the ground (usually, the rear end of the shell 1 contacts the ground), a supporting point is formed, when the gravity center of the whole toy animal crosses the supporting point, the toy animal rolls backwards, and the action of the toy animal for backwards tumbling is realized. When the tail end of the arc-shaped rack 44 passes over the swing rod transmission gear 42 of the rib-turning bucket, the smooth part on the circumferential surface of the driving disc 34 corresponds to the swing rod transmission gear 42 of the rib-turning bucket, at the moment, the driving disc 34 cannot drive the swing rod transmission gear 42 of the rib-turning bucket to rotate, and the swing rod 42 of the rib-turning bucket can reset under the action of the torsion spring.
