Theodolite type laser coarse pointing mechanism

The invention discloses a theodolite type laser coarse pointing mechanism which comprises a pitch axis assembly and a pitch auxiliary supporting assembly which are installed on the two side walls of aU-shaped frame respectively. An azimuth axis assembly penetrates through the bottom face of the U-shaped frame to be installed, the two ends of the load are respectively connected with the pitching shaft assembly and the pitching auxiliary support assembly, and the two ends of a pitch axis locking arm are respectively connected with the load and a pitch axis locking and releasing device. A coil part and an armature part of a parking electromagnet are respectively connected with the pitch axis locking and releasing device and the pitch axis locking arm, the two ends of the azimuth axis lockingarm are respectively connected with the U-shaped frame and the azimuth axis locking and releasing device, and a light path assembly is arranged at the outer side of the pitching auxiliary supportingassembly.
