The difference from the first embodiment is that the specific structure of the transmission member 51 is different.

As shown in fig. 16 and 17, in the present embodiment, the transmission member 51 is rotatably provided in the housing 10, and a part of the outer wall thereof is provided with the spiral track and the other part thereof is not provided with the spiral track, so that a spiral section and a non-spiral section are formed on the circumferential side of the transmission member 51, and the spiral section and the non-spiral section alternately oppose the protruding end with the rotation of the transmission member 51, thereby being press-fitted and escape-fitted to the protruding end 431, respectively. Specifically, when the unlocking piece 20 is located at the initial retraction position, the protruding end 431 is aligned with the non-spiral section and is circumferentially staggered with the spiral track, at this time, on one hand, the movement of the spiral track does not affect the protruding end 431, so that the authorized magnetic member 41 is kept at the unauthorized position, and on the other hand, the spiral track does not interfere with the subsequent movement of the protruding end 431, so that when the unlocking piece 20 moves to the working position, the protruding end 431 can smoothly extend into the rotation range of the spiral track; when the unlocking sheet 20 is located at the working position, the protruding end 431 is located at the end of the spiral track and can extend into the rotating range of the spiral track so as to be in extrusion fit with the spiral track, and at the moment, only the driving member 51 needs to be driven to rotate, and due to the spiral shape of the spiral track, the protruding end 431 can be extruded, so that the authorization magnetic member 41 moves to the authorization position; when the reset is performed, the transmission member 51 rotates reversely, the protruding end 431 is always abutted to the spiral track under the action of the reset member 60 until the protruding end 431 moves to the end of the spiral track, the protruding end 431 is aligned with the non-spiral section again, and the unlocking piece 20 can move back to the retraction position smoothly.

In this embodiment, the authorization assembly 50 further includes an authorization driving member 52, the authorization driving member 52 is a motor and is drivingly connected to the transmission member 51 so as to drive the transmission member 51 to rotate, the transmission member 51 of this embodiment is disposed in a cylindrical shape, one end of the transmission member 51 is connected to the authorization driving member 52 through a D-shaped opening, and the rotation axis of the authorization driving member 52, i.e., the rotation axis of the transmission member 51, is parallel to the movement track line of the unlocking sheet 20, so that the spiral track on the circumferential side of the transmission member 51 can be engaged with the protruding end 431. Of course, besides the above-mentioned arrangement, the specific rotation manner, structure shape, etc. of the transmission member 51 may also adopt other manners as required, as long as the movement of the authorized magnetic member 41 can be realized by intermittently cooperating with the protruding end 431.

Optionally, the transmission member 51 may further be provided with a limit structure, which is engaged with a corresponding portion of the housing 10 for stopping, so as to control the rotation range of the transmission member 51.

The authorized magnetic part 41, the transmission magnetic part 42 and the transmission part 51 of the present embodiment all use magnetic steel, and of course, other types of magnetic parts may be used as needed.
