adjustable keyboard bracket mechanism includes fixed seat provided with first axle for use as pivot and rotatable second axle; bracket set including first support with one end thereof fastened to the first axle and the second axle and the other end thereof provided with third axle, second support having one end thereof fastened to the second axle and the other end thereof provided with fourth axle and adjustment device set fastened to the third axle and the fourth axle, the adjustment device set including rotating adjustment block having two opposite sides thereof respectively provided with first friction wheels and two mating friction blocks each having inner side thereof provided with second friction wheel for fitting the first friction wheel to form the positioning or rotating adjustment status of the adjustment device set; and connecting seat assembled on the rotating adjustment block opposite to the third axle and the fourth axle.

Adjustable keyboard bracket mechanism

An adjustable screen lift arm includes a support frame assembly with a frame base, a balance adjustment mechanism including a gear set consisting a drive gear and a sector-like driven gear, a gear rack meshed with the drive gear and a spring connected between the frame base and the driven gear, and a holder block assembly has a holder block body that combined with the gear rack and a first sliding rail, the other side combined with a second sliding rail. When the holder block body is moved vertically, the gear rack rotates the drive gear, causing the driven gear to stretch or compress the spring so that the arm of force is relatively changed to offset the spring force of the spring, enabling the holder block assembly to be freely adjusted to the desired elevation and then automatically positioned.
