After the probes are fixed, the sliding block 21 is moved, the spring 19 rebounds, the limiting block 14 resets, and the gear 13 is limited, realizing the rapid fixing of multiple probes. To improve usability, the first cylinder 3 is activated, moving the pressure plate 8 and displacement sensor 33. The displacement sensor 33 measures the distance moved. The pressure plate 8 moves the circular rod 7 and pressure sensor 32. When the pressure sensor 32 contacts the probe, it detects the pressure on the probe. The signal receiver 17 receives the signals from the displacement sensor 33 and pressure sensor 32. When the elasticity of a probe is detected or the probe breaks, the control panel 16 activates the second cylinder 28, moving the circular rod 7 and square block 29. The circular rod 7 slides from the inner wall of the circular groove 30 into the limiting groove 5, thus fixing the position of a probe. Other probes that have not yet yielded elasticity can continue to be tested. The elasticity of multiple probes can be detected simultaneously and automatically, improving usability.
