Abstract
The invention discloses a pair of fork type shark pincers and belongs to the field of shark pincers devices. The pair of shark pincers comprises a pincers jaw in a U-shaped structure, a pincers body slidably installed in a deck and an oil cylinder located below the deck. Wherein the pincers jaw is installed at the top of the pincers body, and a telescopic end of the oil cylinder is connected with the pincers body. The pair of shark pincers further comprises a guide rail and a guide supporting frame, wherein one end of the guide supporting frame is sliably connected with the guide rail, the other end of the guide supporting frame is connected with the pincers body, and the guide rail is installed in a cabin below the deck. Due to the fact that the guide rail and the guide supporting frame are installed at the bottom of the pincers body, the pincers body can be drawn by the guide rail and the guide supporting frame when the pair of shark pincers can ascend or descend. When the pair of shark pincers is operated, the pincers body and the pincers jaw are not prone to rotate, clamping of next ascending of the pincers body cannot be influenced, and stability is good.
