The frame 704 is provided with a mounting mechanism 8 which is rotatably connected to the adjustment limit frame 7. The mounting mechanism 8 includes a worm B801, which is rotatably connected to the arc frame 704 through the worm B801. The outer end of the worm B801 is connected and fixed with a knob B802. The inner ends of the worm B801 are meshed and driven with worm wheels B803. The worm wheel B803 is rotatably connected to the arc frame 704 through a transmission rod 804.
