the driving mechanism drives the clutch piece (143) to rotate, so that when the clutch piece (143) is separated from the locking structure, the locking hook (130) is switched from the locking state to the unlocking state, in the process, the torsion spring (145) stores elastic potential energy along with the rotating shaft (144), and after the clutch piece (143) is separated from the locking structure, the torsion spring (145) releases the elastic potential energy to push the clutch piece (143) to move towards the direction far away from the driving mechanism along the limiting groove (121) until the clutch piece (143) is separated from the driving mechanism.

5. The electronic padlock according to claim 1, characterized in that the locking structure comprises a reset portion, which is urged against the clutch (143) by an external force to restore the coupling of the clutch (143) with the driving mechanism.

6. The electronic padlock according to claim 5, characterized in that the locking structure comprises a locking groove (131) and a yielding groove (132), wherein the locking groove (131) and the yielding groove (132) are both arranged on a side wall of the shackle (130), the depth of the locking groove (131) is smaller than the depth of the yielding groove (132), the locking groove (131) is located at the bottom of the yielding groove (132), and the reset portion is a slope connecting section (133) located between the locking groove (131) and the yielding groove (132);

the locking hook (130) is under the action of external force to be switched to the locking state from the unlocking state, when the locking structure and the clutch piece (143) are in the same plane, the clutch piece (143) slides into the yielding groove (132) under the action of the twisting force of the twisting assembly, at the moment, the external force is applied to the locking hook (130) to enable the clutch piece (143) to slide into the locking groove (131) along the inclined surface connecting section (133), the clutch piece (143) can move towards the direction close to the driving mechanism to be in driving connection with the driving mechanism, and the locking hook (130) is switched to the locking state.

7. The electronic padlock according to claim 2, characterized in that the rack portion (1431) comprises a circular arc shaped rack, the torsion assembly comprising a rotation shaft (144), the centre of the circular arc shaped rack being located on the axis of the rotation shaft (144).

8. The electronic padlock of claim 3, wherein the protrusion (1432) is an elongated structure, the torsion assembly comprising a pivot (144), the elongated structure being perpendicular to the pivot (144).

9. The electronic padlock according to claim 6, wherein the lock body assembly is provided with a mounting hole (122), and the lock housing (110) is provided with a yielding hole (112) corresponding to the mounting hole (122);

the locking hook assembly further comprises an elastic element (170), the elastic element (170) is installed at the bottom of the installation hole (122), the bottom end of the locking hook (130) is pressed on the elastic element (170), and in the process that the locking hook (130) is switched from the unlocking state to the locking state, the elastic element (170) exerts upward elastic force on the locking hook (130) so that the clutch piece (143) is connected with the driving mechanism.

10. The electronic padlock of any one of claims 1 to 9, further comprising:

an electronic circuit board (160), the electronic circuit board (160) being mounted on the lock body assembly, the drive mechanism being electrically connected with the electronic circuit board (160);

a Hall element mounted on the electronic circuit board (160);

the magnetic steel (180), the magnetic steel (180) is installed on the latch hook (130).
