a motor and a clutch push plate are also arranged in the lock body shell, a screw shaft connected with the motor drives the clutch push plate to linearly move left and right, and a clutch pin is assembled on the middle shifting block and is pushed by the clutch push plate to move left and right; when the door is opened outwards, an information card equipped with a lock key of the lock gives a corresponding signal to a motor on the lock, the motor is electrified and rotated after receiving a correct signal to drive a clutch push plate to move rightwards, the clutch push plate pushes a clutch pin to move rightwards along a guide hole of a middle shifting block to control the coaxial linkage of the lower shifting block and the middle shifting block, when the lower shifting block is rotated downwards clockwise outside the door, the lower shifting block rotates to push the clutch pin blocked in a rotating track to drive the shifting blocks to synchronously rotate, the middle shifting block rotates to drive a main gear and a transmission gear to rotate, and a middle shifting fork rotating synchronously with the transmission gear is driven to control a square bolt component to retract to realize the door opening function; meanwhile, the lower shifting peach is rotated anticlockwise outside the door, and the central rotating block synchronously rotates reversely to idle.

6. The anti-theft lock with the lock shifting fork clutch control mechanism according to claim 5, characterized in that the lock body shell is further provided with a safety bolt assembly and a safety bolt poking control, and the safety bolt poking control controls the safety bolt assembly to extend out of or retract into the lock body shell.

7. The anti-theft lock with the shifting fork clutch control mechanism for the lock is characterized in that a safety bolt assembly and a safety bolt poking handle are further arranged in the lock body shell, and the safety bolt poking handle controls the safety bolt assembly to extend out of or retract into the lock body shell; a push rod, a safety tongue linkage sheet and a safety tongue poking sheet which are in transmission connection with each other are further arranged between the lock cylinder poking handle in the lock body shell and the middle poking peach of the shifting fork device, the safety tongue poking handle is in poking connection with the safety tongue poking sheet through the safety tongue linkage sheet, the left and right linear motion of the push rod pushes the safety tongue poking sheet which takes a fulcrum as a center to perform deflection motion, and a raised head matched with the lock cylinder poking handle is arranged on the lower side of the push rod; under the state that the safety tongue assembly, the square tongue assembly and the latch tongue assembly are all stretched out and closed, the lock cylinder dial is rotated clockwise outside the door through the mortise lock cylinder, the lock cylinder dial drives the middle dial peach to rotate through the push rod, the middle dial peach drives the main gear of the shifting fork device to rotate, the main gear drives the middle shift fork to rotate through the transmission gear of the shifting device, the square tongue assembly is pulled to retract, meanwhile, the middle dial peach drives the latch tongue assembly to retract, in addition, the push rod pulls the safety tongue dial sheet, the safety tongue dial sheet drives the safety tongue dial peach to deflect through the safety tongue linkage sheet, the safety tongue assembly is pulled to retract, and the rapid door opening outside the door is realized.
