[0114] Secondly, the second adjusting screw can be rotated by rotating the third hand wheel, so that the pressing sleeve 393 can be raised or lowered, so that the sole plate 394 can be adjusted to a suitable position;

[0115] Finally, the movement of the first drive motor 311 drives the first rotating sleeve 313 to rotate, thereby driving the screw of the second screw nut mechanism 32 to descend, driving the first fixed plate 36, the pressure sensor 37 and the first pressure block 38 to descend, and when the first pressure block 38 contacts the second U-shaped hanging plate 341, it drives the first adjustment frame 34, the second adjustment frame 35 and the downward pressure assembly 39 to move downward until the sole plate 394 contacts the balancing car 5, and the pressure sensor 37 starts to display the pressure value until the specified pressure value is reached, and the dynamometer 4 starts to work.
