The utility model relates to a novel firm centre gripping of rock specimen device has following advantage:
1. the device has simple structure, easily understood principle and convenient operation;
2. the device can clamp rock samples with various sizes, has high fault tolerance rate on the sizes of rock sample test pieces, and is suitable for the existing rock sample sampling technology;
3. the device has high cycle speed in one-time cutting, and can simultaneously cut a plurality of rock sample test pieces at one time, thereby improving the efficiency of cutting rock samples;
4. the device greatly improves the stability of clamping the rock sample, solves the problems of deviation cutting and skew cutting when cutting the rock sample, and improves the quality of the rock sample test piece;
5. the device has added securing device, has guaranteed even when rock test piece size and recess agree with so much, also can make the test piece stabilize among the recess.
