Camera platform locking device

A camera platform locking device, comprising:

• a housing, for preventing the components from exiting;
• in said housing from the top down are configured:
• a sphere, for providing a support to the camera;
• a locking mechanism, arranged underneath said sphere, for working with said housing to lock said sphere inside the housing;
• a platform base, arranged underneath said locking mechanism, and fixedly connected to the housing, for providing a support to said locking mechanism;
• said locking mechanism, comprises a primary regulating assembly for ordinary regulation and a secondary regulating assembly for fine regulation, said primary regulating assembly comprises a primary screw bolt, and a primary knob configured at the end of the primary screw bolt and arranged outside the housing;
• said primary screw bolt has two screw threads that are reversely structured to each other;
• two primary driving components having inclined surfaces are in threaded connection with corresponding screw threads on the primary screw bolt;
• the inclined surfaces of the two primary driving components are oppositely arranged to each other, for driving the sphere to move up and down through their reverse movement;
• and
• said secondary regulating assembly comprises a secondary screw bolt, and a secondary knob arranged on the secondary screw bolt, which is also arranged outside the housing;
• said secondary screw bolt has a screw thread;
• a secondary driving component having a inclined surface is placed on the screw thread and is in threaded connection with it, for driving the sphere to move up and down through its relative movement to the sphere;
• the thread pitch of the secondary screw bolt is less than that of the primary screw bolt.
