The pliers for the preparation of test samples consists of a frame (3), which is fast connected with a rigid part (1) of a handle and a cylinder (6) with a filling chamber (8). In the cylinder (6), which is concluded by a closure (7), moves a piston (5), connected with a moving part (2) of the handle by a rod (4). In the process of preparation of the test samples, after the release of the closure (7) the filling chamber (8) of the cylinder (6) is filled with the sample and the closure (7) is closed. Action of the hand to the moving part (2) of the handle transfers the acting force by the rod (4) on the piston (5), following after the release of the closure (7) takes out the sample in the pellet form. |
