[0033] refer to figure 1 , Clutch-type security anti-theft lock, including a key 1 and a lock body 8, the lock body 8 is provided with a lock cylinder 2 and a deadbolt shift block 9, both of which are separate structures. The opening and closing of the lockset is realized after the dead bolt shifting block 9 is dialed forward or backward. The left side of deadbolt shifting block 9 is lock core 2, and the right side is provided with knob shaft 11, and knob shaft 11 and dead bolt shifting block 9 joint shafts rotate, and knob shaft 11 connects the knob handle that is positioned at the right side of lock body 8, twists The knob handle drives the deadbolt shifting block 9 to rotate through the knob shaft 11, so as to realize the effect of opening the lockset on the opposite side of the lock cylinder.
[0034] The lock cylinder 2 is provided with a lower pin storehouse which is convenient for the lower pins to move up and down, and the lower pins are placed therein. The lock body 8 is provided with an upper pin storey which is convenient for the upper pins to move up and down. The upper pin storey is located directly above the lower pin storehouse. There are upper marbles placed therein, and the upper marbles correspond to the lower marbles one by one.
[0035] It also includes a shaft coupling device for coaxial rotation after the dead bolt shift block 9 is connected with the lock cylinder 2. The shaft coupling device includes a motor 14, the motor 14 is located on the right side of the knob shaft 11, and the motor shaft extends into the left side. In the hollow cavity of the knob shaft 11 with openings at both ends, a knob shaft connector 20 threadedly connected with the motor shaft is sleeved at the end of the motor shaft extension. The outer wall of the connector 20 is provided with a protrusion which is convenient to be inserted into the slot. There are two card slots, which are arranged at the opposite position of the end face of the opening of the knob shaft 11, and the slotting direction is the left and right directions, so that the protrusions that are convenient to be inserted into it can move left and right along the slotting direction, correspondingly, snap into the There are also two protrusions of the card slot, which are located at opposite positions on the outer wall of the knob shaft connector 20 . After the motor 14 is powered on and receives the control signal, the motor shaft rotates counterclockwise, so that the knob shaft connector 20 rotates counterclockwise together. The rotation is restricted behind the card slot, so that it can only move in the axial direction, and its effect is to make it move towards the direction of the lock cylinder. The right side of the lock cylinder 2 is provided with a lock cylinder connector 22 which facilitates the joint rotation of the lock cylinder 2 and the deadbolt shifting block 9 . A left and right through chamber is arranged inside the deadbolt shifting block 9, and the lock cylinder connector 22 is placed in the chamber.
