Preferably, the fixing device is a fastening sleeve, a threaded connection section is arranged on the right side of the sleeving connection section, the fastening sleeve is connected to the threaded connection section in a threaded mode, and the right end of the worm sleeve is in contact with the fastening sleeve.

Preferably, a thread locking glue is coated between the screwing section and the fastening sleeve.

Compared with the prior art, the beneficial effects of the utility model are that:

1) The arrangement of the nitride film improves the hardness of the surface of the worm, reduces the abrasion of the surface of the worm in the process of meshing with a worm wheel, and further prolongs the service life of the worm;

2) The worm shaft and the worm sleeve are detachably connected, when the worm sleeve is worn greatly due to long-time use, the worm sleeve can be detached and replaced independently, the whole worm does not need to be replaced, and the cost is reduced.
