The invention discloses a protective scaffold for fixed displacement of personnel. The protective scaffold comprises an operation platform, wherein mounting plates are symmetrically arranged on the two sides of the two ends of the top of the operation platform, rapid locking assemblies are arranged at the tops of the ends, close to each other, of the two mounting plates, supporting legs are arranged at the four corners of the bottom of the operation platform, clamping grooves are formed in the middle positions of the sides, close to each other, of the two supporting legs, a protective net is hinged to the tops of the sides, close to each other, of the two clamping grooves, hinge rods are hinged to the tops of the two sides of the protective net, and clamping blocks are arranged at the bottoms of the sides, close to each other, of the two hinge rods. Through mutual cooperation of the protective net, the hinge rods, the clamping grooves and the clamping blocks, the lower portion of the scaffold can be shielded and protected, the situation that tools of constructors accidentally fall off and hurt people below can be effectively prevented, the safety guarantee of the constructors below is improved, and the protective property of the scaffold is improved.
