An embodiment of the utility model provides a pair of lockset, including tool to lock body and shutting subassembly, the shutting subassembly sets up in the tool to lock originally internally. Referring to fig. 1, the locking assembly includes a driving motor 10, a spiral knob 11 and a locking member 2, the spiral knob 11 is connected to the driving motor 10 and rotates under the driving of the driving motor 10, the spiral knob 11 has a spiral gap 114, and one end of the locking member 2 extends into the spiral gap 114. When the lock is unlocked and locked, the drive motor 10 can drive the screw knob 11 to rotate, the screw knob 11 rotates and acts on the locking member 2 extending into the screw gap 114, so that the locking member 2 slides in the screw gap 114 and moves along the length direction of the screw knob 11, and the lock is locked and unlocked. Specifically, helical gap 114 may be larger than the end of latch 2 that extends into to allow latch 2 to slide unimpeded in helical gap 114 while also allowing friction between latch 2 and helical knob 11 to be reduced, reducing the degree of wear on both. Compared with the meshing transmission of the gear and the rack adopted in the prior art, the technical scheme adopted by the embodiment has the advantages of relatively simple structure, lower requirement on the matching precision inside the locking assembly and longer service life.

In a specific application, the driving motor 10 may drive the spiral knob 11 to rotate forward and backward to move the locking member 2 in the unlocking direction and the locking direction, the forward rotation of the spiral knob 11 may correspond to unlocking the locking member 2, and the backward rotation may correspond to locking the locking member 2, and of course, the operations of the forward rotation and the backward rotation corresponding to the locking member 2 may be opposite according to the rotation direction of the spiral gap 114. For convenience of explanation, the present embodiment takes the direction in which the latch 2 moves closer to the driving motor 10 as the unlocking direction, and the direction in which the latch moves away from the driving motor 10 as the latching direction.

As an alternative embodiment of the present embodiment, referring to fig. 1 and fig. 2, the screw knob 11 includes a buffer portion 111 and a screw portion 112 having a screw gap 114, a first end of the buffer portion 111 is connected to the driving motor 10, a second end of the buffer portion 111 is connected to the screw portion 112, and one end or/and the other end of the screw gap 114 is an open end. In a specific application, when the spiral knob 11 rotates, the locking member 2 slides in the spiral gap 114 and moves toward the end of the spiral gap 114, and after the locking member 2 slides to the end of the spiral gap 114, if the spiral knob 11 continues to rotate, the locking member 2 can slide out of the spiral gap 114, and at this time, even if the spiral knob 11 rotates, the locking member 2 cannot continue to move.
