Abstract
A speed increasing bidirectional mechanical converter, including a main shaft and a speed increasing planet gear unit is disclosed. The speed increasing planet gear unit includes a first ring gear, a planet gear, a sun gear and a planet carrier, wherein the planet gear is mounted on the planet carrier. The planet gear is arranged between the first ring gear and the sun gear, and rotates in an opposite direction against the sun gear. The speed increasing bidirectional mechanical converter further includes a reversing means, via which the first ring gear and the sun gear drive the main shaft. When in use, the planet carrier is kept still, and the main shaft rotates in the preset direction. The speed increasing bidirectional mechanical converter realizes the direction reverse by using the speed increasing planet gear unit, which simplifies the structure, facilitates the manufacture and decreases the space it occupies and its weight. A screwdriver and a wrench having the speed increasing bidirectional mechanical converter are provided.
