[0009] The adjusting device comprises a limiting nut located above the limiting block and a supporting nut located below the limiting block. The adjusting part is a threaded rod, and the limiting block is provided with a through hole corresponding to the position of the threaded rod.

[0012] The number of the support columns is multiple and they are evenly distributed along the circumference of the truncated cone.

[0013] The push-pull force testing module comprises a digital push-pull force gauge sensor, the upper part of which is connected to the limit block by bolts, and the lower part is provided with a fisheye bearing detachably connected to the output end of the actuator.
