The invention discloses an active multi-stage variable-frequency outward yield device. The active multi-stage variable-frequency outward yield device comprises an inner steel pipe and an outer steel pipe. The assembly end of the inner steel pipe is sleeved with and fixed to the assembly end of the outer steel pipe, and the inner steel pipe is provided with a plurality of outer pipe walls surrounding the inner steel pipe and is provided with outer hoops with different shearing strength. According to the active multi-stage variable-frequency outward yield device, the inner steel pipe is provided with the outer hoops with the different shearing strength, so that step-by-step yield is achieved, and therefore the device can automatically change the yield resistance value and multi-stage yield deformation according to the surrounding rock pressure and deformation; and the problems that current support deformation is limited by the material property, and a current supporting product is single in load yield are solved.
