Abstract
A rotating direction change device for a microtome includes: a first shaft arranged in a first fixed position; a first gear wheel non-rotatably mounted to the first shaft; a second shaft movable in a first direction; a second gear wheel non-rotatably mounted to the second shaft; a third shaft movable in a second direction; a third gear wheel non-rotatably mounted to the third shaft; and a first connection part connecting the second shaft and the third shaft such that the second gear wheel is constantly meshed with the third gear wheel, in which the second gear wheel can be driven by the first gear wheel directly or indirectly. Hence, the rotating direction change device has advantages of simple structure and low friction.
