The safety protection device comprises a base, a first supporting structure and a second supporting structure, the first supporting structure comprises a bent column, a transverse rod and a limiting structure, the bent column comprises multiple sections of single columns hinged in series and an abutting disc, and the transverse rod is hinged to the upper end of the bent column; elastic tightening pieces are arranged between the bending columns and the cross rod and between the bending columns and the base in a hinged mode, the bending columns are sleeved with the first limiting structures, the second limiting structures comprise mutually-hinged limiting rods, the limiting rods are hinged between the adjacent bending columns in a crossed mode, and the second supporting structures comprise main supporting columns and buffering bent rods. The device can solve the problems that when a maintainer carries out maintenance on the car roof, the car roof shakes easily, maintenance is inconvenient, body fatigue of the maintainer is aggravated, the maintainer easily falls down and hurt, related components of the car roof are cracked up, and under the condition that a buffer above an elevator shaft fails, an elevator suddenly ascends to rush to the roof due to faults or misoperation of the maintainer, and the safety of the elevator is affected. And the maintenance personnel are very easy to be injured.
