A positioning plate 10 is fixedly connected to the side of the rocker arm 9 away from the connecting block 8. The side of the positioning plate 10 away from the rocker arm 9 contacts the surface of the steel 2.

[0036] As a technical optimization solution of the utility model, by providing the connecting block 8, the rocker rod 9 and the positioning plate 10, the steel material 2 can be squeezed and fixed when it is lifted to a high place, thereby reducing the impact of vibration on the stability of the steel material 2.
