[0010] Furthermore, a bearing is fixedly installed inside the guide groove, and the threaded rod is fixedly connected to the inner ring of the bearing, and one end of the threaded rod extends to the inside of the groove.

[0011] Furthermore, a knob is arranged inside the groove, and one end of the threaded rod is fixedly connected to the outer wall of the knob.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses a threaded rod and a threaded sleeve to adjust the spacing between the No. 1 gear and the No. 2 gear according to the use conditions when using the adjustable precision gear shaft. The position of the guide plate can be adjusted by adjusting the adjustment component and the threaded sleeve, and then the driving position of the No. 2 shaft body can be adjusted, and then the spacing between the No. 1 gear and the No. 2 gear can be adjusted, which is convenient for adjusting the spacing between the No. 1 gear and the No. 2 gear according to the installation and use conditions, thereby improving the flexibility of the adjustable precision gear shaft.

[0014] 2. The utility model provides the guide groove and the guide plate. When the spacing of the adjustable precision gear shaft is adjusted, the cooperation between the guide plate and the guide groove can make the second shaft body move smoothly, thereby avoiding the shaking of the adjustable precision gear shaft and affecting the use accuracy.
