Tensile anchor clamps of simple and easy ring

The utility model relates to a tensile anchor clamps of simple and easy ring, its characterized in that: it includes anchor clamps (1) and lower anchor clamps (2), go up anchor clamps (1) including the vertical setting in upper portion by door shaped frame (1.2) of grip block (1.1) and its lower extreme, door shaped frame (1.2) all are provided with through -hole (1.3) including the wallboard of two parallels and vertical setting in the same position of two wallboards, alternate between two through -holes (1.3) mandrel (3), anchor clamps (2) are the same with last anchor clamps (1) structure down, and both set up the position relatively. During the use, the proof test machine clip respectively anchor clamps, down anchor clamps by the grip block, put into cyclic annular sample between anchor clamps and time anchor clamps to in arranging door shaped frame in, plug the mandrel, the pulling force is applyed to the sample to the proof test machine can. Simple structure, convenient to use.
