Abstract: An automatic power transfer switching mechanism includes several links and a push member. The links move to rotate the push member. The push member has two push portions configured to push two power switches. The push member is rotatable about a first axis located between the two push portions so that when one of the push portion moves forwards, the other push portion moves backwards. Therefore, when one push portion moves forward to push one power switch on, the other push portion moves backwards to simultaneously push the other power switch off. The power transfer can be switched automatically without delay.

Abstract: An intermittent linear movement control device includes: movement elements flexibly connected to one another and each having a sliding groove at a lower surface thereof; each sliding groove has an upper portion thereof as an arcuate sliding groove and two sides thereof as gap-like dissected half-length sliding grooves, with the dissected half-length sliding grooves in communication with the arcuate sliding groove, and the dissected half-length sliding grooves of respective movement elements joined with each other for forming a full-length sliding groove; and a small pulley flexibly connected in one of the sliding grooves and capable of performing eccentric rotations by forces received; wherein, the plurality of movement elements horizontally and linearly moves forward when the small pulley moves in the full-length sliding grooves, and remains at halt when the small pulley moves in idle in the arcuate sliding grooves.

Abstract: A turning disc intermittent rotary mechanism in accordance with the invention includes at least one top disc flexibly mounted to a bottom seat, wherein at the center of the top disc is provided with a through hole and the bottom surface thereof is provided with sliding slots; and a main driving wheel flexibly mounted to the bottom seat using a round through hole provided in advance, wherein at the side of the upper surface of the main driving wheel is provided with a small pulley that is disposed in the sliding slots and is capable of sliding. Consequently, the force produced by the small pulley acting at the long sliding slot thereof is effectively reduced, thereby lengthening the lifespan of the force transmission mechanism including the small pulley and the main driving wheel.
