The wrench assembly abuts on the limit sleeve, and the wrench assembly is capable of driving the limit sleeve to slide. A limiting component is disposed at a lower end of the center rod, the limiting component may be built into the bottom plate to fit the limit sleeve in a locking manner, and a first elastic element is disposed between the limit sleeve and the bottom plate through fitting.
