ABSTRACT:
A keyboard carrier for adjusting elevation and inclination of a keyboard position thereon includes a locating mechanism, which includes an outer sleeve, a braking block axially movably disposed in the outer sleeve, a screw rod having an end pivotally connected to the keyboard carrier and the other end perpendicularly extended through the outer sleeve and a round hole on the braking block, a handle located at an end of the outer sleeve, and a pivoting mechanism connected to an inner end of the handle and having a screw bolt screwed into a central axis of the braking block. When the handle is pivotally turned to axially move the braking block in the outer sleeve with the screw rod engaged with a threaded section on the round hole of the braking block, the keyboard carrier is stably supported by the screw rod without the risk of moving.
