During actual assembly, the light equalizing plate 12 is coaxially pressed on a hole shoulder in a cylinder cavity of the knob cover 11, and the pressing operation is realized through the spacer 13; the light homogenizing plate 12 is arranged to diffuse light and make the light more uniform and more suitable for visual observation. The transparent connecting shaft 14 is fixed in the knob cover 11 by a set screw 90, and presses the spacer 13 axially by the transparent connecting shaft 14 to press the light equalizing plate 12.

The entire rotary knob cover 11 is rotated by the rotary bearing 80 provided at the end of the rotary knob cover 11. The outer ring of the slewing bearing 80 is fixed at the tail end of the knob cover 11; while the inner race of the slew bearing 80 is interference fit on the bearing mount 42 and is snap-fit into place by the shaft snap 44. The whole bearing seat 42 is sleeved on the outer wall of the shaft sleeve 40, sequentially penetrates through the flange plate 41 on the shaft sleeve 40 and the fixing plate 16 through axial screws, and then is screwed on the bearing seat 42, so that the purpose of integrally and fixedly connecting the bearing seat 42, the fixed seat 20 and the shaft sleeve 40 is achieved.

The encoder 30 is fixed at the rear end of the sleeve 40 as shown in fig. 1-4. In order to ensure the operation feel of the invention, the invention is additionally provided with a damper 70 shown in figures 3-4 on the basis of the structures of figures 1-2. Specifically, the fixed cylinder 60 is first coaxially continued rearward at the rear end of the sleeve 40.
