[0016] As Figure 1 , Figure 2 and Figure 3As shown, a manual gimbal for astronomical visual observation is provided, comprising a horizontal rotation mechanism and a vertical rotation mechanism. The vertical rotation mechanism consists of a first fixed shaft 3, a second fixed shaft 10, a cantilever 2, and a support 4. The first fixed shaft 3 and the second fixed shaft 10 are located on both sides of the support 4. The first fixed shaft 3 passes through the cantilever 2 and is connected to the cantilever 2 via a locking ring 24. The second fixed shaft 10 passes through the cantilever 2, and is connected to the cantilever 2 on the side of the support 4 via an adjusting ring 14 and a friction plate 25. The other side of the second fixed shaft 10 is connected to the cantilever 2 via a vertical locking ring 9, a pressure ring 12, and an anti-loosening washer 13. A sliding groove is provided at the lower part of the cantilever 2, and the sliding groove passes through... The handwheel 8 is connected to the counterweight 7 via bolts and counterweight locking. The horizontal rotation mechanism consists of a horizontal rotating body 5 and a fixed seat 6. The horizontal rotating body 5 is located at the lower end of the bracket 4 and is connected to the fixed seat 6 via friction plate 26. The outer side of the horizontal rotating body 5 is connected to the inner side of the fixed seat 6 via cylindrical surface mating. A central shaft 23 is provided at the center of the bracket 4, the horizontal rotating body 5, and the fixed seat 6. The central shaft 23 is connected to the bracket 4 via a horizontal locking nut 15, a disc spring 16, and a spring washer 17.

The central shaft 23 is connected to the fixed seat 6 via a flange nut 21 and a spring washer 22. The horizontal rotation mechanism, through flange nut 18 and disc spring 20 pressing bearing 19, forms suitable damping between fixed seat 6, friction plate 26, and horizontal rotating body 5, controlling flexible and comfortable horizontal rotation. The engagement of the outer side of the horizontal rotating body 5 with the inner cylindrical surface of the fixed seat 6 reduces swaying and vibration. The horizontal rotation is fixed by pressing bracket 4 with horizontal locking nut 15, disc spring 16, and spring washer 17.
