Stone fixture is a new and practical auxiliary tool for transporting stone, which includes lifting ring, tie rod, lifting arm, splint and so on. The working principle is: between the lifting ring or tie rod and the lifting arm is provided with a group or several groups of action arm greater than the transmission lever transmission mechanism.

　　The use of stone fixture:

　　1, the stone lifting clamp, stone fixture to the upper end of the workpiece, the four clamping block lift (can be used to lift the rod or lift the hook), so that the four clamping block and the workpiece cylinder has a certain gap, the fixture sleeve to the workpiece in a certain position, so that the clamping block can fully contact the cylinder.

　　2. Loosen the lifting rod or lift the hook, the weight of the four clamping blocks droops, and the rubber sheet fixed on the clamping block contacts with the workpiece cylinder.

　　3. The ring body is lifted by the truck or forklift, and the workpiece weight drives the clamping block to move relatively parallel to the cylinder through static friction. Because the Angle between the middle line of the connecting plate and the horizontal line is less than the relative friction Angle between the workpiece and the rubber sheet, and is also less than the relative friction Angle between the rubber sheet and the clamping block, the workpiece weight makes the clamping workpiece rise through friction self-locking.

　　4. The lifting work is finished, the workpiece is placed, the clamping block is loosened, the clamping block is lifted with the lifting rod or the lifting hook, the lifting fixture, the stone lifting clamp and the stone clamping fixture are completed.
