<p>A screw rod transmission apparatus (17), an electronic device (15), and a desk. The screw rod transmission apparatus (17) comprises a motor device (172) outputting a driving force, and a screw rod (173) driven by the motor device (172). A screw rod nut (174) is engaged on the screw rod (173); the screw rod nut (174) moves along the screw rod direction when driven by the motor device (172); the motor device (172) is connected to the screw rod (173) via a gear (179); the gear (179) driven by the motor device (172) is meshedly engaged with the gear (179) on the screw rod (173). The screw rod transmission apparatus (17) is controlled by a small motor device (172), and drives the screw rod (173) for transmission under the meshing engagement of the gears (179), so that the screw rod nut (174) on the screw rod (173) can be driven to move along the screw rod direction, thereby allowing the screw rod transmission apparatus (17) to be applied to different apparatuses and application environments.</p> |
