A pivot braking structure includes a sliding-guided frame, a sliding seat, a pivot-shaft assembly and a movable cover. The sliding seat slides along a sliding rail of the sliding-guided frame and connected to a shaft hole of the sliding seat. The pivot-shaft assembly is provided with a pivot shaft passing through the shaft hole of the sliding seat. The movable cover is pivotally jacketed to the pivot shaft. Recesses are provided on a positioning member and protrusions are provided on the movable cover, so that the movable cover is positioned at a predetermined opening angle relative to the sliding seat by pivoting the protrusions of the movable cover to embed in the recesses of the positioning member. The movable cover is provided with a clip portion having an accommodation portion jacketed to the edge of the sliding-guided frame when the movable cover is attachably received to the sliding seat.
