ABSTRACT:
A knuckle arm interconnects a machine body and a top cover of a machine, and includes a base fixed on the machine body, and a pivot seat connected pivotally to the base and attached to the top cover. A biasing unit is disposed between the base and the pivot seat so as to bias the top cover to pivot upwardly. A friction assembly imparts a resistance to pivoting of the top cover so as to maintain the top cover at any position.
