During pitch rotation, the pitch motor drives the worm to rotate, and the worm drives the worm wheel to rotate. Utilizing the self-locking function of the worm gear, the pitch turntable remains locked after the pitch motor stops, improving positioning accuracy. Please refer to [link / reference]. Figures 1-5 It includes: a horizontal turntable 100, a pitch drive mechanism 200 and a pitch turntable 300.

[0033] The horizontal turntable 100 includes a horizontal motor 110, a horizontal support platform 120, a pitch support frame 130, a drive bracket 140, and a slide 150.
