Disclosed is a double linkage triggering system including a main body, which has a trigger unit and a shooting unit. The trigger unit is capable of being contacted with the shooting unit. The trigger unit comprises a bracket body, a trigger block, a hammer, a trigger power-adjusting bolt, a triggering mechanism and a trigger-safety device. The hammer is hinge connected to the bracket body. The trigger block is hinge connected to the bracket body and each end of the trigger block is respectively capable of being limited by the hammer and the trigger power-adjusting bolt. The shooting unit has a sight stand, a guide device, a pressure plate, a rotary latch, a roof plate, a latching plate, a returning device, and an anti-empty shooting mechanism. The returning device is inserted into the roof plate. The roof plate is hinge connected to the latching plate.
