The invention discloses a headrest height adjustment mechanism for a child safety seat. The headrest height adjustment mechanism comprises press blocks, locking blocks and reset springs, wherein the press blocks located on the rear side of the chair seat back are connected with a headrest through connecting parts, a longitudinal channel allowing the connecting parts to penetrate through is formed in the seat back, clamp slots which are uniformly distributed and located at the side parts of the longitudinal channel are formed in the rear side of the seat back, the locking blocks are arranged on the inner sides of the press blocks, and the reset springs are located between the press blocks and the locking blocks. When the rest springs are in a stretching state, the locking blocks are clamped into the clamp slots, and the headrest is fixed on the seat back; the locking blocks are extruded by external force, the reset springs are compressed, and the locking blocks are separated from the clamp slots. The headrest height adjustment mechanism has the advantages that the pressing blocks are pressed by fingers, the reset springs are compressed, the locking blocks are moved out of the clamp slots, the press blocks are pushed to move up and down, the headrest moves up and down to the appropriate height position, after the locking blocks are loosened, the locking blocks are matched with the clamp slots under the action of the reset springs, and the headrest is fixed in the appropriate height.
