The invention discloses a clamping device of a Leeb hardness tester for detecting the hardness of a pipeline. The clamping device is mainly composed of three parts including a pipeline clamping and fixing part, a Leeb hardness tester fixing part and a sliding rail block for the hardness tester to axially slide along a pipeline. By adopting the device, the Leeb hardness tester can be firmly fixed on a detected pipeline and is used for supporting the pipeline very well, so that a phenomenon that the measurement accuracy is influenced through relative displacement or springing in a measurement process is prevented; meanwhile, the Leeb hardness tester can be strictly moved along the axial direction of the detected pipeline through a sliding rail, so that researches and analysis are convenientto carry out. By adopting the device disclosed by the invention, the measurement accuracy of the Leeb hardness tester can be effectively improved. 本发明公开了种管道硬度检测用里氏硬度计夹持装置，该夹持装置主要由管道夹持固定部分，里氏硬度计固定部分以及硬度计沿管道轴向滑动轨道块三个部分组成。该装置可以将
