When testing the strength of the soil, the middle of the pressure plate 12 can be held by hand, and the connecting plate 15 in the middle of the pressure plate 12 can be directly contacted during the holding process. During the compression process, the connecting plate 15 is pressed against the inner wall of the pressure plate 12, so that the two sets of sliding rubber pads 16 can contact the sliding shaft of the test head 11, and the working position of the test head 11 is initially fixed. Conversely, after releasing the support of the pressure plate 12, the rubber pads 16 can be popped out as a whole under the action of the two sets of spring rods 14. This step, together with the setting of the pressure plate 12, allows the two sets of test heads 11 to be pressed down evenly when in use, reducing the uneven pressure of the two sets of test heads 11, which leads to unstable sound wave energy transmission and thus affects the concrete test data. At the same time, the sliding of the two sets of test heads 11 can improve their flexibility during use, and the rubber pads 16 fix their position.

After the fixed plate 24 is continuously opened in this step, it is convenient for its subsequent maintenance work, and under the action of the limiting rod 41, the phenomenon of slippage between the connecting rope 33 and the support frame 4 can be reduced.
