[0002] A wood grabber is a mechanical device installed on the manipulator of an excavator. It is mainly used to grab wood materials such as round logs. It can also be used to grab long strips of materials such as scrap steel and scrap metal. The claw structure of the wood grabber is a mechanical claw specially designed for the manipulator of an excavator, so it has good flexibility.

[0003] A linkage clamping claw structure is disclosed in the Chinese utility model patent with the announcement number CN216180531U, which belongs to the technical field of clamping devices. The linkage clamping claw structure is simple, the end of the clamping piece is a sphere, located in the semicircle at the upper end of the fixing hole, and plays the role of positioning and fixing support. The linkage transmission piece connects the driving connecting shaft and the clamping piece. When the driving cylinder pushes downward, the ear protrusion inside the end of the driving connecting shaft exerts force outward, pushes the clamping part outward, and the clamping claw opens and aligns with the object to be clamped. Then the driving cylinder moves upward, and the ear protrusion outside the end of the driving connecting shaft exerts force inward, pulls the clamping part inward, closes the clamping claw, and clamps the object. Therefore, only the push-pull action of the driving cylinder is needed to complete the clamping and releasing of the packaging material, which is convenient to operate. In the actual use of the wood grabber clamping claw structure, since the weight of the grasped object is heavy, in order to ensure the firmness of the grasping of the object, a wood grabber clamping claw structure is needed, which can increase the friction of the grasped object during the grasping process and improve the firmness of the grasping of the object.
