The first adjusting mechanism 3 includes a housing 31 fixed to the bottom of the mounting plate 1. A first rotating shaft 32 is rotatably connected inside the housing 31. A turntable 34 is fixed to the first rotating shaft 32. A first worm gear 33 is fixedly connected to the first rotating shaft 32. A fixing plate 35 is fixed inside the housing 31. A first motor 36 is fixed to the side of the fixing plate 35. A first worm gear 37 is mounted on the output shaft of the first motor 36. The first worm gear 37 and the first worm gear 33 are meshed and driven. The turntable 34 is rotatably connected to the housing 31. The second adjusting mechanism 4 is mounted on the bottom of the turntable 34 and includes a fixing seat 41 fixed to the bottom of the turntable 34. A second rotating shaft 42 is mounted inside the fixing seat 41. A second worm gear 33 is fixedly sleeved on the second rotating shaft 42. Both ends of the wheel 43 and the second shaft 42 pass through the fixed base 41. A movable frame 44 is fixed to the side of the second shaft 42. A second motor 45 is installed on the side of the fixed base 41. The output shaft of the second motor 45 is inserted into the interior of the fixed base 41 and connected to the second worm gear 46. The second worm wheel 43 and the second worm gear 46 are meshed and driven. The connecting plate 5 is fixed to the movable frame 44. The connecting plate 5 has an L-shaped structure.
