Illustratively, the elastic restoring member 72 is a spring, the spring is sleeved outside the guide post 742 and the guide rod 741, and two ends of the spring respectively abut against the two locking balls 74.

In this embodiment, as shown in fig. 9, the locking mechanism 73 includes a locking top 731, a transmission rod 732, and a driving member 733. The locking top 731 is provided in the insertion part 711 movably in the axial direction of the insertion part 711. The locking top piece 731 is in transmission connection with the transmission rod 732, and the driving piece 733 is used for driving the transmission rod 732 to rotate so as to drive the locking top piece 731 to move along the axial direction of the insertion part 711. When the transmission rod 732 rotates in the forward direction, the locking top piece 731 moves along the axial direction of the insertion part 711 to between the two locking balls 74, and the locking top piece 731 abuts against the two locking balls 74 to lock the two locking balls 74 at the locking position; when the transmission lever 732 rotates reversely, the locking top piece 731 moves reversely along the axial direction of the insertion part 711 and is completely misaligned with the two locking balls 74, so that the two locking balls 74 can move in the mounting hole 7111 relative to the insertion part 711, and can retract from the locking position to the unlocking position. That is to say, the driving part 733 drives the locking top piece 731 to move, so that the locking top piece 731 abuts against the two locking balls 74 or is completely staggered with the two locking balls 74, and then the locking and unlocking of the two locking balls 74 are realized through the locking mechanism 73, so as to realize the locking and unlocking of the electronic lock head 70.

In other embodiments, the driving member 733 may have other configurations, for example, the driving member 733 may be a hydraulic motor.

Optionally, the locking mechanism 73 further includes a driving spring 734, and the driving spring 734 is sleeved outside the transmission rod 732. The transmission rod 732 is provided with two locking projections 7321 which are locked with the driving spring 734, the two locking projections 7321 are respectively arranged at two sides of the transmission rod 732 along the radial direction of the transmission rod 732, and the locking projections 7321 are locked in the gap between two adjacent circles of the driving spring 734. As shown in fig. 11 and 12, the locking top piece 731 has a first abutting surface 7311 and a second abutting surface 7312 which are opposite to each other in the axial direction of the insertion part 711, and the driving spring 734 is located between the first abutting surface 7311 and the second abutting surface 7312. When the transmission rod 732 rotates in the forward direction, the transmission rod 732 can push the driving spring 734 against the first abutting surface 7311 through the locking protrusion 7321 and drive the locking top 731 to move between the two locking balls 74. When the transmission rod 732 rotates reversely, the transmission rod 732 can push the driving spring 734 against the second abutting surface 7312 through the locking protrusion 7321 and drive the locking top 731 to be completely misaligned with the two locking balls 74.

Wherein, the transmission rod 732 pushes the locking top piece 731 to move by the driving spring 734 during the rotation process, so that the driving spring 734 has the energy storage function. When the edge of the two locking plates 30 acts on the two locking balls 74 and presses the two locking balls 74 to retract into the insertion part 711 during the insertion of the insertion part 711 into the locking hole 11, the locking top piece 731 is blocked by the locking balls 74 and cannot move between the two locking balls 74, but the driving piece 733 can continue to drive the transmission rod 732 to rotate to compress the driving spring 734, so as to accumulate the elastic force. After the driving member 733 stops working, if the inserting part 711 is completely inserted into the locking hole 11, the two locking balls 74 extend out of the inserting part 711 under the action of the elastic resetting member 72, so that the locking top part 731 can return to move, at this time, the driving member 733 does not need to continuously drive the transmission rod 732 to rotate, the locking top part 731 can continuously move under the elastic force of the driving spring 734, and thus, the locking top part 731 can move between the two locking balls 74, so as to lock the two locking balls 74.
