[0043] Specifically, such as Figure 3-4 As shown, the bending adjustment assembly 34 includes an adjusting guide rail 341 and a locking member 342.

The required bending angle, number of times and frequency are set through the control panel, and the motor is controlled to start rotating. The motor drives the bending fixture to start rotating through the drive wheel, transmission belt and driven wheel, so that the sample to be tested bends downward along the edge of the test platform. Finally, the bending sensor transmits the measured data to the control panel, and the user can intuitively obtain the test data through the control panel.
