The outer periphery of the three-axis seat 11 is hingedly installed with three equally spaced support rods 12. The support rod 12 is hollow, and a support rod 2 13 is sleeved inside the support rod 12. The support rod 2 13 is movably connected with the support rod 12. A rod buckle 15 is installed at the bottom of the support rod 12 corresponding to the outer periphery of the support rod 2 13. The rod buckle 15 is buckled to the outer periphery of the support rod 2 13 to form a limited support. The middle of the three-axis seat 11 is opened, and a vertical rod 16 is passed through the hole. A tension knob 14 is threadedly connected to the position of the vertical rod 16 on the side of the three-axis seat 11. The end of the tension knob 14 is against the vertical rod 16 to form a mutual support. A top platform 19 is welded and installed on the top of the vertical rod 16. A collar 17 is screwed on the bottom end of the vertical rod 16. A connecting rod 18 is hingedly connected between the outer periphery of the collar 17 and the bottom end of the support rod 12 at the corresponding position.

[0024] The top surface of the top platform 19 is equipped with a two-axis fixed platform 2, which includes a base 21. The base 21 is fixed to the top platform 19 by bolts. A rotating platform 22 is screwed to the top surface of the base 21. An arm 23 is provided above the rotating platform 22. The bottom of the arm 23 is sleeved onto the bearing of the rotating platform 22 to form a sleeve installation and fixation. A steering gear 25 is installed on the arm 23 and is engaged with the gear of the rotating platform 22. A steering gear 26 is bolted to the top position of the side of the arm 23 away from the rotating platform 22, corresponding to the shaft position of the steering gear 26. Arm 1 23 is flanked by arm 2 24 . The shaft of servo 2 26 is connected to arm 24 via a keyed pin. A mounting platform 27 is welded to the top of arm 24 .
