Wherein, the drive component between inner frame and pedestal, outer framework and pedestal can be arranged only at the side of rotary shaft,
The both sides of rotary shaft can be arranged in.
Wherein, column and pedestal can be integral pieces.
The beneficial effects of the invention are as follows：
1, meet two-dimentional adjust automatically speculum can as traditional picture frame type the needs of installing, and position self-locking may be implemented,
Application particularly suitable for specific mounting location in the optical system without quick high frequency correction beam direction.
2, whole to use tower structure, and rotating part and fixed part are connected by drive component, running accuracy
It is higher with overall stiffness, there is good processing and assembly process process.
