The invention relates to a lock body with a split hole site and heaven and earth rods. The lock body comprises a shell, a gear box, a main bolt unlocking mechanism and a
spoke bolt unlocking mechanism. A bottom plate
assembly, a cover plate and a guide plate are combined with one another to form the shell, and the gear box, the main bolt unlocking mechanism and the
spoke bolt unlocking mechanism are arranged in the shell. The gear box is connected with the main bolt unlocking mechanism through
gear transmission, and the main bolt unlocking mechanism controls extension and retraction of the heaven and earth rods through
gear transmission so as to control locking and unlocking of the
spoke bolt unlocking mechanism. The main bolt unlocking mechanism comprises a transmission part, a
handle unlocking part, a square bolt unlocking part and an inclined bolt part, wherein the transmission part, the
handle unlocking part, the square bolt unlocking part and the inclined bolt part are fixed to the bottom
assembly. The spoke bolt unlocking mechanism comprises a pair of heaven and earth rod unlocking parts placed in parallel and spoke bolt unlocking parts which are arranged on the two sides of the shell and controlled by the heaven and earth rod unlocking parts. The lock body further comprises a
locking mechanism which is used for limiting retraction of the heaven and earth rods. According to the lock body, locking and unlocking of heaven and earth hooks and spring bolts are realized through the transmission connection among gears, shifting wheels and racks and through the gear box or a
handle.
