Abstract: A mechanical transmission of an optical pick-up head is disposed inside the casing of an optical disk drive for sliding the optical head between a worm shaft and a pressing block, which has a flexible embedded section; wherein the pressing block has a pair of elastic arms and the front end of the elastic arm has an embedded section for embedding the worm shaft; an elastic plate, with one of its end being pressed against the embedding section, and the other end being pressed by the embedded section, by means of the elasticity, the embedded section is also embedded into the worm shaft by elastic pressing. In the sliding movement of the optical head, or the rotating worm shaft brings the embedded section into movement until it ends its journey, the pressing embedded section is detached from the worm shaft. Alternatively, when the worm shaft reverses its rotation, the embedded section will be embedded into the warm shaft again by pressing.
