[0011] Furthermore, a rubber pad is fixedly connected to the bottom of the fixing threaded hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting the groove, fixing screws and fixing threaded holes, the connecting end of the shaft can be inserted into the groove, and ensure that the through groove of the connecting end of the shaft is aligned with the fixing threaded hole. At this time, the personnel can rotate the fixing screw so that its bottom passes through the through hole of the connecting end of the shaft and makes its bottom fixedly connected to the fixing threaded hole, thereby fixing the connecting end of the shaft in the groove. Subsequently, the personnel can connect the flange to the external mechanism, so that the shaft is connected and fixed to the external mechanism through the flange. BRIEF DESCRIPTION OF THE DRAWINGS
