Trojan horse holder

       Trojan horse gripper is a tool commonly used in geological drilling and other fields to clamp drilling tools or casing at the hole opening. It is mainly composed of eccentric seat, shaft, slip, connecting rod, crank, etc. Its working principle is to use an eccentric structure. When two eccentric seats with elliptical hammerheads rotate downwards along their pivot points, they will push the slip forward, thereby clamping the clamped object such as the drill rod.
