The invention discloses a car seat unlocking labor-saving structure which comprises a connecting plate, a plate spring, a pull tab, a transmission shaft of an angle regulator, a handle of the angle regulator, an L-shaped connecting bar and a connecting bar; wherein, the plate spring is assembled together with the connecting plate by the transmission shaft of the angle regulator, the bending end of the L-shaped connecting bar is connected on the connecting plate, one end of the connecting bar is connected with one end of the L-shaped connecting bar, and the other end of the connecting bar is connected with the handle of the angle regulator; the other end of the L-shaped connecting bar is connected with the pull tap, and the handle of the angle regulator and the transmission shaft of the angle regulator are connected with each other and rotate together; therefore, a connecting rod structure is formed by the handle of the angle regulator, the L-shaped connecting bar and the connecting bar. By adopting a simple connecting rod mechanism, the passengers at the back row can easily realize the rapid unlocking of front row seats to achieve the function of quick passing in and out, thereby being convenient for the passengers at the back row to pass in and out; furthermore, the structure is simple, and the cost is low.
