A limiting hole 15 is provided at the center of the lower surface of the grab head 14, and a sliding hole 16 is provided at the center of the inner top wall of the limiting hole 15. A pull rod 17 is slidably connected to the inner wall of the sliding hole 16, and a piston column 18 is fixedly connected to the top of the pull rod 17. The outer wall of the piston column 18 is slidably connected to the inner wall of the piston cylinder 13, and a hook portion 19 is fixedly connected to the bottom of the pull rod 17. The piston column 18 slides inside the piston cylinder 13 to limit the piston column 18, and the pull rod 17 slides inside the sliding hole 16 to limit the pull rod 17.

[0028] In one embodiment, specifically: holes 21 are opened on both sides of the lower surface of the grabbing head 14 near the limiting hole 15, and the inner walls of the two holes 21 are fixedly connected with magnets 22. Since the foam cotton contains iron-containing substances, it is convenient to magnetically absorb the foam cotton through the magnets 22.

[0029] In one embodiment, specifically: the outer wall of the hook portion 19 is slidably connected to the inner wall of the limiting hole 15, and the upper part of the hook portion 19 slides into the limiting hole 15, so that the limiting hole 15 squeezes the two claws on the hook portion 19 to grab the foam cotton.

[0033] In one embodiment, specifically: the hook portion 19 is used to grab the foam cotton inside the mobile phone shielding cover. The hook portion 19 facilitates grabbing the foam cotton inside the mobile phone shielding cover, thereby accelerating the speed of clamping the material.

[0034] When the utility model is working: by connecting the connecting nozzle 23 to an external vacuum device, the internal gas of the piston cylinder 13 is extracted through the vacuum device, so that the internal pressure of the piston cylinder 13 is negatively pressurized, thereby pulling the piston column 18 upward, and then driving the pull rod 17 upward, and the pull rod 17 moves upward, thereby driving the upper part of the hook claw part 19 to slide into the limiting hole 15, and then the limiting hole 15 squeezes the two claws on the hook claw part 19 to grab the foam cotton. At the same time, because the foam cotton material is light and contains iron-containing substances, the foam cotton is magnetically adsorbed by the magnet 22, thereby assisting the hook claw part 19 to grab the foam cotton, thereby improving the material absorption rate and accelerating the speed of clamping the material.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
