The invention discloses an elevator safety protection buffer which comprises a fixing base, a spring hydraulic shock absorber is arranged in the center of the fixing base, spring lifting shock absorbers are arranged on the periphery of the fixing base, a transverse buffer is further arranged between the spring hydraulic shock absorber and the spring lifting shock absorbers, and each spring lifting shock absorber comprises a fixing cylinder, a lifting cylinder, a first spring and an ejector rod. The ejector rod is arranged in the lifting cylinder and extends out, a first spring is arranged between the ejector rod and the lifting cylinder, the lifting cylinder can ascend and descend along with the action of the transverse buffer, and the transverse buffer comprises a connecting rod, a sliding plate, a transverse rack and a second spring. The second spring is arranged between the sliding plate and the fixing cylinder. Multi-stage buffering is formed through the springs and hydraulic pressure, and the buffering effect is improved.
