The invention discloses a clothes hanger lifter with an anti-falling function and particularly relates to the field of lifting clothes hanger accidental falling prevention. The clothes hanger lifter comprises an anti-falling device and a lifter, and a shell of the anti-falling device is fixedly connected with the lifter. The anti-falling device comprises the shell and a brake column. A cavity is formed in the shell, two parallel planes are arranged in the cavity, a guide groove is designed in each plane, and the brake column is erected in the guide grooves and can rotate and move in the grooves. In the initial state, the gap between the brake column and the surrounding is slightly smaller than the diameter of a traction rope. When the brake column moves upwards, the gap becomes smaller, and the traction rope penetrates through the gap. When the traction rope is slowly pulled, the brake column only rotates at the bottoms of the guide grooves. When the traction rope is quickly pulled in the falling direction, the brake column overcomes gravity and moves upwards along the guide grooves, the traction rope is clamped, and falling of a lifting clothes hanger is prevented. The clothes hanger lifter is simple in structure and low in cost, can reliably and effectively prevent the lifting clothes hanger from falling, and avoids property loss and personal injuries.
