Optionally, the clamping block is arranged at the lower end of the clamping arm so as to be rotatable around a rotating shaft, and the rotating shaft and the hinge shaft in the middle of the supporting arm are arranged parallel to each other.

Optionally, an elastic member for maintaining a stable relative position between the clamping block and the clamping arm is provided between the side of the clamping block away from the clamping action surface and the clamping arm. The elastic member may be a spring or an elastic rubber strip.

Optionally, the clamping action surface of the clamping block is covered with a rubber cushion, and the rubber cushion is used to increase the static friction force with the surface of the square marble.

Optionally, the position of the limit block can be adjusted along the length direction of the support arm so as to adjust the position according to the different thicknesses of the square marble.

Optionally, the two ends of the suspending rope are respectively connected to the upper ends of the support arms of the two clamp bodies with adjustable lengths, and the middle of the suspending rope is provided with knots and hooks for hanging on the lifting arms of the construction machinery. Or hanging rings.

The beneficial effects of the present utility model: the utility model is provided with two clamp bodies which are arranged crosswise and hinged together in the middle, and a front end of the two clamp bodies is provided with a clamping arm, a clamping block and a limit block. The clamping part is connected to the upper ends of the two support arms with the suspension rope, and the suspension rope is lifted by the front fork of the forklift, so that the clamping blocks at the front end of the two clamp bodies clamp the opposite two sides of the marble to complete the clamping of the marble. The clamping force is large, and there is no need to set a rope at the bottom of the marble or put the front fork deep into the bottom of the marble, which prevents the damage to the marble caused by the above operations, and is suitable for hoisting the marble on the flat ground. The setting of the limit block can facilitate that the heights of the two clamp bodies are consistent with respect to the marble.
