[0002] The existing clamping equipment for carrying material is usually composed of two or more clamping jaws, and the clamping equipment is suitable for clamping and carrying relatively regular and hard material. When clamping and carrying bagged material, the bag body is more fluid, so it will fall off. To solve this problem, the traditional clamping jaw structure is designed into a flexible clamping jaw structure, the clamping jaw is longer in size and has more degrees of freedom, so that the clamping jaw can tightly hold the bagged material from multiple sides, effectively solving the problem of bag body falling off. Since the flexible clamping jaw structure has more degrees of freedom, the structure is more complex. If the grasping force is insufficient, the material will fall off. If the grasping force is too large, the bag body will be broken and the material will leak. Therefore, a pressure sensor needs to be installed on each clamping jaw and each degree of freedom to adjust the grasping force through the value feedback by the pressure sensor, so as to better grasp the bagged material. However, in actual use, if the bagged material needs to be grasped and unloaded at the same time, as the material in the bag body continuously decreases, the bag body becomes softer. Even the flexible clamping jaw with multiple degrees of freedom is difficult to stably clamp, and the bag body will fall off with the material. SUMMARY
