[0026] The torsion spring 8, the engaging rod 81 and the top plate 82 are further included, the top plate 82 is located below the handle rotating wheel 51 and abuts against the pin rod 6, the motor 2 drives the engaging rod 81 to rotate, the torsion spring 8 has one end engaged with the engaging rod 81 and the other end located in the top plate 82 and constitutes the working state of the motor 2 driving the pin rod 6 in the vertical direction, the motor 2 drives the engaging rod 81 to rotate and drive the torsion spring 8 to move, one end of the torsion spring 8 is engaged with the engaging rod 81 and the other end acts on the top plate 82, the top plate 82 abuts against the pin rod 6, so that the rotary motion of the motor 2 is converted into the linear movement of the pin rod 6 in the vertical direction, the driving of the pin rod 6 is realized; when the motor 2 stops, the torsion spring 8 and the top plate 82 keep acting on the pin rod 6, so that the stable linkage state is ensured; the motor 2 power is efficiently transmitted to the pin rod 6 by the torsion spring 8 and the top plate 82, the linear driving in the compact space is realized, and the energy loss is reduced; the design improves the response speed and the control precision, makes the clutch work more reliably, and at the same time, when the battery power supply is interrupted, the mechanical mode can be used to maintain or reset, so that the emergency performance is enhanced.

[0027] The reset mechanism 7 includes a reset block 71, a spring 72 and a pressing block 73. The shell 1 is provided with a communication hole 74. The spring 72 is arranged in the shell 1 and drives the reset block 71 to move along the communication hole 74. The pressing block 73 is arranged outside the shell 1 and has a pressing state of pressing the reset block 71 into the shell 1. A torsion spring 8 is arranged at the center of the reset block 71 and moves with the reset block 71. When the pressing block 73 is in the pressing state, the torsion spring 8 is separated from the clamping rod 81 and the top plate 82. When the pressing block 73 is not in the pressing state, the torsion spring 8 is in contact with the clamping rod 81 and the top plate 82. That is, the position of the reset block 71 is taken as the center of the lever, and the two ends of the torsion spring 8 are the two ends of the lever. When the motor 2 works, the one end of the torsion spring 8 clamped by the clamping rod 81 moves downward, and the other end is in contact with the top plate 82, so as to move upward and drive the pin rod 6 vertically. In the normal state, the center of the torsion spring 8 is arranged on the reset block 71 and is in contact with the clamping rod 81 and the top plate 82, so that the motor 2 cannot drive the pin rod 6. When the full-automatic lock cannot work due to power failure or other unexpected situations, the user removes the pressing block 73. Under the action of the spring 72, the reset block 71 moves outward. At this time, the torsion spring 8 is driven to move, so that the torsion spring 8 is in contact with the clamping rod 81 and the top plate 82 respectively. Then, the NFC component 3 supplies power to the motor 2. The motor 2 can drive the clamping rod 81 and drive the torsion spring 8 to move, and drive the top plate 82 to move upward, so that the pin rod 6 constitutes the linkage between the handle rotating disc 5 and the square rod rotating wheel 4, and the lock is opened. After that, the pressing block 73 is put back. Under the action of the pressing block 73, the reset block 71 moves inward. At this time, the two ends of the torsion spring 8 are separated from the clamping rod 81 and the top plate 82 respectively, the top plate 82 moves downward, and the reset is completed. Because the power provided by the NFC is limited, the motor 2 cannot rotate in both directions. Therefore, through the mechanical mechanism, the force provided by the torsion spring 8 is released, the lock is unlocked, and the pressing block 73 can be arranged as a slider which moves perpendicularly to the shell 1. The middle of the handle can be left for the sliding of the pressing block 73.

[0028] The shell 1 is provided with a lock cylinder 9 arranged at the bottom and rotating. The lock cylinder 9 is provided with a key hole 91 at the bottom and a rotating inclined surface 92 at the top. The top plate 82 is provided with a matching inclined surface 83 matched with the rotating inclined surface 92. When the user inserts the mechanical key to rotate the lock cylinder 9, the rotating inclined surface 92 interacts with the matching inclined surface 83 at the bottom of the top plate 82 to drive the top plate 82 to move, and then drive the pin rod 6 to realize the linkage between the handle rotating disc 5 and the square rod rotating wheel 4, and complete the manual unlocking. The mechanical key is integrated as a backup unlocking mode. When the power supply of the NFC fails or the motor 2 fails, the user can directly unlock by using the key. The design improves the emergency compatibility and practicality of the lock, and ensures that the user can reliably unlock in any situation.

[0029] The top plate 82 is arc-shaped and matches the shape of the handle rotating wheel 51. When the motor 2 is driven or manually operated, the top plate 82 keeps stable contact with the handle rotating wheel 51, ensuring smooth movement of the pin rod 6 without jamming or friction interference. The arc-shaped top plate 82 improves the matching degree and movement coordination between components, reduces wear and noise, and prolongs the service life of the clutch. At the same time, the design optimizes the space layout, makes the overall structure more compact, and improves the stability and response efficiency of the clutch.

[0030] Working process: When the full-automatic lock is not powered, the user moves away the pressing block 73, and the reset block 71 moves outward under the action of the spring 72, which drives the torsional spring 8 to move, so that the torsional spring 8 abuts against the clamping rod 81 and the top plate 82, respectively. Then, when the user uses the NFC device to approach the lock, the NFC assembly 3 supplies power to the motor 2, and the motor 2 drives the clamping rod 81 to rotate, thereby driving the torsional spring 8 to move. The torsional spring 8 takes the center on the reset block 71 as a fulcrum, and makes the other end act on the arc-shaped top plate 82, thereby converting the rotary motion of the motor 2 into the vertical movement of the top plate 82. The top plate 82 pushes the pin rod 6 to slide upward, so that it is simultaneously inserted into the pin through hole 53 on the handle rotating wheel 51 and the pin slot 54 on the handle rotating disc 5, thereby connecting the handle rotating disc 5 and the handle rotating wheel 51. Since the handle rotating wheel 51 keeps engagement with the square rod rotating wheel 4 through the engagement part 52, rotating the handle rotating disc 5 can drive the square rod rotating wheel 4 to realize unlocking. After unlocking, the pressing block 73 is put back, the reset block 71 moves inward, and the torsional spring 8 is forced to separate from the clamping rod 81 and the top plate 82. The top plate 82 moves downward, drives the pin rod 6 to exit the pin through hole 53 and the pin slot 54, and thereby releases the linkage under the action of the reset mechanism 7. In addition, when mechanical emergency unlocking is needed, the key is inserted to rotate the lock cylinder 9, and the rotating slope 92 at the top of the lock cylinder 9 interacts with the matching slope 83 at the bottom of the top plate 82, which can directly drive the top plate 82 and the pin rod 6 to move upward, and also can establish linkage to realize unlocking.
