By stretching in and out at 11, locking and unlocking of the latch 2 are implemented.

When the latch controller 3 operates in the case 1 around the pedestal 31, the protrusion block 3121 rotates in the rotary groove 142, and the protrusion block 3121 of the rotary groove 142. When contacting either side, the latch controller 3 stops rotating.

When the motor 5 cannot operate normally, the locking and unlocking of the latch 2 can be controlled by using a manual key. Specifically, the manual key is inserted into the keyhole 311 to manually operate the key. When rotating, the latch controller 3 rotates the pedestal 31 around the base 31 in the case 1, thereby inducing the operation member 32 to control the expansion and contraction of the latch 2.

When the motor 6 is stopped, when the manual key is rotated by the latch controller 3, the latch controller 3 causes the driven gear 41 to move through the connector 43 and the pushing member 42. The driven gear 41 meshes with the drive gear 61, and further, by inducing the drive gear 61 to generate a load, the latch controller 3 is rotated by means of a manual key to Controlling locking and unlocking is not so easy.

Thus, when the latch 2 extends or retracts into the lock ring 11, the motor controller 5 controls the driven gear 41 to return to the initial position. In detail, the latch 2 When extending or contracting to the lock ring 11, the contact portion 421 of the propulsion member 42 is not located in the sensitive member 52, and after a certain time, the sensitive member 52 receives an inverted signal. To the motor (6), the motor (6) causes the driven gear (41) to return to its initial position through the drive gear (61), furthermore, guides the propulsion member (42) in the guide groove (44). Rotate in to return to the initial position, the pushing member 42 is not in contact with any one side of the guide groove 44, the connector 43 does not rotate together. When operating the latch controller 3 with a manual key, the driven gear 41 is positioned in the initial position, the latch controller 3 guides the connector 43 to rotate, and guide grooves 44 installed in the connector 43. ) Rotates accordingly, so that the pushing member 42 does not move in a stationary state in the guide groove 44 all the time, and the driven gear 41 rotates without contacting any one side of the guide groove 44. Since no load is generated because it is not induced, it becomes easier to control the expansion and contraction of the latch 2 with a manual key.

The above has described the specific embodiment of the present invention in detail. Those skilled in the art can understand that various modifications and improvements can be made to the present invention without departing from the principles thereof, and the modifications and improvements are also included in the protection scope of the claims of the present invention.
