The invention provides a switching hook of a crane lifting hook. The switching hook comprises a switching part and a hanging part, wherein the switching part comprises a switching ring, a switching loop is formed in the space in the switching ring, and the switching loop is of a closed quasi-circular structure, the hanging part comprises an object hanging ring and an anti-falling block, a U-shapedobject hanging loop is formed in the space in the object hanging ring, and the switching ring is fixedly connected with the object hanging ring. The switching hook has the advantages that through unique angle design, the switching hook of the crane lifting hook is designed, conversion connection between the crane lifting hook and a gas turbine tool lifting eye is achieved to complete assembly operation of a gas turbine, and the situation that due to mismatching of connection, operation is difficult, and potential safety hazards are caused is prevented, meanwhile, an automatic anti-disengagingfunction is achieved, an anti-disengaging block is automatically located at the position limiting disengaging of the lifting hole in the object lifting ring during lifting, and use safety is improved, the switching hook is integrally formed and welded, so processing cost is saved while the strength is ensured.
