US Patent 11032926 Transmission device used for monitor expansion

The present invention discloses a transmission device used for expanding monitors, comprising the body, and a combination of at least a first monitor, a second monitor and an actuation module that can be installed thereon. The actuation module can drive the second monitor to move reciprocally on a reference axis X; and the second monitor is provided with a drive module to drive the second monitor to move reciprocally on a reference axis Y perpendicular to the reference axis X, which jointly provide a mechanism, under which an expansion and combination of the screen of the first monitor and the screen of the second monitor (in the same planimetric position) and/or retraction thereof are enabled.
