The invention provides a plate spring for a low-temperature refrigerator and the low-temperature refrigerator. The plate spring for the low-temperature refrigerator is composed of a supporting plate and a spring arm body coaxially and fixedly installed on one end face of the supporting plate. The supporting plate is annular, and a plurality of outer mounting holes are formed in the supporting plate in the circumferential direction; the spring arm body is provided with a plurality of spring arms arranged in a central symmetry mode, a center hole is formed in the center of the spring arm body, a plurality of inner mounting holes are formed in the periphery of the center hole, and the inner mounting holes are connected with the center hole through open grooves. The tail end of each spring arm is provided with a fixing plate which is bent towards the same end face, and the fixing plates are fixedly connected with the outer edge of the supporting plate. Compared with a vortex arm plate spring, the linear spring ar
