[0053] When this utility model is in operation:

[0054] In this embodiment, the mechanism is used as the inner core of an electric plush toy dog.

[0055] The first motor M1 rotates forward to drive the left front half shaft 9, right front half shaft 10, left rear half shaft 15, and right rear half shaft 16 to rotate, cooperating with the left front eccentric cam 11, right front eccentric cam 12, left rear eccentric cam 17, and right rear eccentric cam 18, and cooperating with the left front foot 3, right front foot 4, left rear foot 5, and right rear foot 6 to complete the walking action. Reversing the rotation completes the action of the left front foot 3 and right front foot 4, and the left rear foot 5 and right rear foot 6 being aligned.

[0056] The second motor M2 rotates forward to drive the left front axle sleeve 39, right front axle sleeve 40, left rear axle sleeve 44, and right rear axle sleeve 45 to rotate. This, in conjunction with the left front swing arm 42, right front swing arm 43, left rear swing arm 46, and right rear swing arm 47, and with the left front foot 3, right front foot 4, left rear foot 5, and right rear foot 6, completes the actions of inverting, sitting down, lying down, and doing push-ups.

[0057] The first motor M1 drives gears A21, B22, C23, D24, F26 to mesh and move. Simultaneously, the first transmission shaft 29 transmits power to gear G27. When the first motor M1 rotates forward, it drives the four legs to walk. When walking, it touches either the first limit switch N1 or the second limit switch N2 and then reverses 270° to align the front left and right legs, as well as the rear left and right legs. Only then can the second motor M2 be driven to achieve the actions of inverting, sitting, lying down, and doing push-ups. The first motor rotating forward and touching the first limit switch N1, then reversing 270°, results in an inverted position; rotating forward and touching the second limit switch N2, then reversing 270°, results in sitting.

[0058] The second motor M2 drives gears J49, K50, L51, M52, N53, Z76, and O54 for meshing and transmission. At the same time, the second transmission shaft 58 transmits power to gears P55 and Q56. When the second motor M2 rotates forward, it reaches the limit position 62 for lying down and the limit position 66 for sitting and inverted. When the second motor M2 reaches the return-to-center position 65, it is the normal walking position. The sitting and inverted positions 66 and 64 move up and down, and the lying down position 62 and push-up position 63 move up and down.

[0059] The second motor M2 rotates forward and backward at the push-up position 63 and the sitting position, respectively, while the first motor M1 rotates forward to complete the prone walking and sitting walking movements.
