The utility model drives the upper and lower driving parts to move relatively simultaneously so as to drive the upper and lower clutch pins to move relatively, and the clutch pins are inserted into or withdrawn from the clutch pin holes of the rotor so as to realize mutual locking or unlocking. Therefore, synchronous locking or unlocking is realized, the connection stability of the rotor and the clutch can be effectively ensured, and meanwhile, the production cost is ensured by adopting a single driving element.

In particular, relative movement means that when the upper driving member moves downward, then the lower driving member moves upward.

Specifically, the cross section of the arc-shaped slot 510 is in a T-shape, which is configured to limit the position of the limiting block 410 in the arc-shaped slot 510, and prevent the limiting block 410 from moving up and down relative to the arc-shaped slot 510 while preventing the driving member 50 from moving up and down. To achieve this, when the clutch 20 rotates, the clutch pin 40 follows the rotation, and the stopper 410 moves in the arc-shaped slot 510 to avoid interference, which affects the inability of the clutch pin 40 to rotate.

Referring to fig. 1-4, the driving mechanism 60 includes a driving disc 610 rotatably disposed in the lock body 10, a rotation axis of the driving disc 610 and a rotation axis of the clutch 20 are coaxially disposed, driving portions 620 are disposed on an upper side and a lower side of the outer side of the driving disc 610, a chute 630 is disposed on the driving portion 620, a guide post 550 is disposed on the driving member 50 and is inserted into the chute 630, a worm wheel 720 is disposed on an outer wall of the driving disc 610, a driving motor 710 is mounted in the lock body 10, and a worm 730 for meshing with the worm wheel 720 is disposed on a motor shaft of the driving motor 710.

Referring to fig. 2 and 3, when the driving motor 710 drives the worm 730 to rotate, it drives the worm wheel 720 to rotate, so that the driving plate 610 rotates with the rotation axis of the clutch 20, and during the rotation, the position of the driving part 620 changes, and under the extrusion of the chute 630, it can push the guide post 550 located in the chute 630 to move upwards or downwards, and when moving, it can drive the driving part 50 to move upwards or downwards. Simple structure, driving stability is good, and worm wheel's cooperation moreover, it has the auto-lock nature, brings better security.

In particular, the chute 630 is shaped as shown in fig. 2 and 3. When the driving disk 610 rotates clockwise, it can drive the lower driving member 50 to move upwards, and simultaneously drive the upper driving member 50 to move downwards. In this process, the clutch pin 40 can be inserted into the clutch pin hole 310 to achieve the interlocking of the clutch 20 and the rotor 30. Conversely, when the driving disk 610 rotates counterclockwise, the clutch pin 40 is withdrawn from the clutch pin hole 310, thereby separating the clutch 20 and the rotor 30 from each other.

Specifically, the guiding function of the guiding bolt 540 not only restricts the front, back, left and right positions of the guide rail 520, but also restricts the guide rail 520 to move up and down.

Further, in the lock body 10, two threaded posts 530 are longitudinally spaced corresponding to each guide rail 520, that is, each guide rail 520 is guided by matching two guide bolts 540.

Specifically, the first bearing 600 is mounted on the outer wall of the rotor 30, and the driving disk 610 is mounted on the outer ring of the first bearing 600.

Specifically, referring to fig. 1, an installation cavity 220 is provided at the rear end of the clutch 20, the rotor 30 is rotatably disposed in the installation cavity 220, a limit gland 200 is installed at the rear end of the clutch 20, and a front side wall surface of the limit gland 200 is attached to a rear side wall surface of the rotor 30.

Specifically, referring to FIG. 1, the clutch 20 is rotatably mounted within the lock body 10 using a second bearing 230.
