[0025] Specifically, when it is necessary to fix the pressure gauge 36, the hydraulic rod 19 is started to pull the connecting plate 11 inward, and through the action of the connecting rod, the connecting plate 11 drives the first linkage column 14, and the first linkage column 14 drives the second linkage column 16 to move. At the same time, under the limiting action of the first guide rail 9, the two clamping plates 12 move inward at the same time, so as to achieve the effect of clamping the second fixed plate 32, thereby fixing the equipment as a whole, so that during the test, the spring stroke will not be affected by the shaking of the equipment, resulting in errors in the data displayed by the pressure gauge 36, and ultimately affecting the accuracy of the experiment.
