[0031] The working principle of the above embodiment is: the spindle rigidity measuring device,

[0032] 1) When in use, by setting a limit assembly, the limit rod 13 is pulled to the right through the rectangular through hole 19, and the limit rod 13 moves to the right and is pulled out from the inside of the connecting groove. At the same time, the limit spring 12 is stretched.
