The invention provides a hanger fixture for hoisting a spring. The hanger fixture comprises a hanging base plate, wherein the direction, corresponding to the circumferential direction of a to-be-hoisted spring, of the hanging base plate is defined as the circumferential direction of the hanging base plate; the direction, corresponding to the radial direction of the to-be-hoisted spring, of the hanging base plate is defined as the radial direction of the hanging base plate; the hanging base plate is pivoted with more than two hinging arms capable of swinging along the radial direction of the hinging base plate; the lower ends of the hinging arms are provided with hook heads used for hooking spiral spring silks of the spring, the more than two hinging arms are uniformly distributed along the circumferential direction of the hinging base plate, the hook heads on the lower ends of the hinging arms are respectively bent outwards in a manner of departing from each other. Because the hook heads on the lower ends of the hinging arms are respectively bent outwards in a manner of departing from each other, when the spring is hoisted, each hoisting arm is capable of stretching into the spring, and when each hinging arm is strutted along the radial direction of the hoisting base plate, the hooking heads at the lower ends of each hinging arms hook the spiral spring silks of the spring from the interior, and then the spring is upward hoisted, so that the transfer of the spring is finished. The hoisting tool is positioned in the spring during a hoisting process, the hoisting tool is relatively low in hoisting space requirement and high in universality.
