Preferably, a protection spring 302 is sleeved on the piston rod of the protection driving cylinder 301, when the protection driving cylinder 301 is in a non-working state, the protection spring 302 is in a compressed state, and when the protection spring 302 is in a compressed state, the distance between the two supporting blocks 303 is greater than the length of the connecting frame 23. So that the protective drive assembly does not normally interfere with the normal upward or downward movement of the gripper drive assembly to move the gripper to grip or release the object. Preferably, the free length of the protection spring 302 enables the support block 303 to slide along the slide rail 304 to below the gripper driving assembly under the action of the protection spring. That is, when the protection driving cylinder 301 is in the working state, the piston rod of the protection driving cylinder moves towards the gripper driving assembly, and at this time, the protection spring is in the free state under the action of the elastic force, so that even if the gas and power are cut off at this time, the protection spring cannot be compressed.

Further preferably, the gripper driving assembly comprises a driving cylinder 201 and a connecting frame bottom plate 231, the bottom of the driving cylinder 201 is fixed on the connecting frame bottom plate 231, the top of the driving cylinder passes through the support top plate 221 and extends upwards, wherein an insertion hole 220 allowing the top of the driving cylinder 201 to pass through and move upwards and downwards is arranged on the support top plate 221, and the bottom of the piston rod of the driving cylinder 201 is fixedly connected with the support bottom plate 223. When the driving cylinder 201 works, the cylinder body moves upwards to drive the connecting frame bottom plate 231 to move upwards, and the connecting frame bottom plate 231 moves upwards to drive the gripper to clamp the object. And the drive cylinder body when the downstream, then can drive the link bottom plate downstream, and then drive the tongs and loosen the article, consequently through the below of connecting plate bottom plate under the supporting shoe supporting role that makes protection drive assembly, can prevent moving down of link bottom plate under the inefficacy condition, and then prevent that the tongs from loosening the article.

Preferably, a sliding member 306 is disposed on the top of the supporting block 303, and stop members 233 are disposed on both sides of the bottom of the connecting frame bottom plate 231, so that when the gripper is in a state of clamping the object, the sliding member 306 can slide to the inner sides of the stop members 233 and stop at the inner sides of the stop members 233. Preferably, the slider 306 is a rolling wheel structure. Preferably, the roller structure is fixed to the top of the supporting block 303 by a rotating shaft. The longitudinal section of the stop member 233 is in a right triangle structure, wherein the hypotenuse of the longitudinal section of the stop member 233 is disposed toward the outside, one of the right-angled sides of the longitudinal section of the stop member 233 is fixedly connected with the bottom of the connecting frame bottom plate 231, and the other right-angled side is vertically disposed. The arrangement of the rolling wheel structure can facilitate the sliding part to roll along the bevel edge of the stop part to enter the inner side of the stop part. Under the condition of unexpected air and power failure, the driving cylinder of the gripper driving assembly fails and slides downwards, but the protection driving cylinder fails and cannot drive the supporting block to slide back because the spring is in a non-compressed or non-extended state, and the mechanical gripper assembly can be always stopped below the connecting frame bottom plate 231 under the elastic action of the protection spring 302, so that the mechanical gripper assembly is protected from loosening articles.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
