Through being equipped with mounting hole 513, can make things convenient for external handle or other one end that make things convenient for manual structure of holding to insert mounting hole 513 internal fixation to when making things convenient for manual control, external force passes through the handle effect on pivot 511, drives second gear 52 rotation.

The inner diameter of the communication hole 521 is identical to the outer diameter of the rotation shaft 511, and the first limiting groove 512 is opened along the axial direction of the rotation shaft 511, and the length of the first limiting groove 512 is equal to or greater than the length of the roller 53, so that the entire roller 53 can be conveniently matched with the first limiting groove 512.

The second gear 52 is meshed with the seventh gear 45, and the seventh gear 45 can drive the second gear 52 to rotate; the first gear 51 is meshed with the rack 6, so when the first gear 51 rotates, the rack 6 can be driven to move relative to the first gear 51, and then the locking piece 2 is driven to move, so that unlocking or locking is achieved.

When the first limiting groove 512 is opposite to the second limiting groove 522, the distance between the bottom of the first limiting groove 512 and the bottom of the second limiting groove 522 is greater than the outer diameter of the roller 53.

The width from the bottom of the first limiting groove 512 to the opening is gradually increased, the depth of the first limiting groove 512 is smaller than the outer diameter of the roller 53, and the width from the bottom of the second limiting groove 522 to the opening is gradually increased.

As shown in fig. 2, 7 and 9, when the motor 3 is started, the motor 3 drives the second gear 52 to rotate through the gear set 4, and when the second gear 52 rotates, one side wall of the second limiting groove 522 pushes the roller 53 to move, so that the roller 53 can be pressed between the second limiting groove 522 and the outer wall of the rotating shaft 511; along with the continuous rotation of the second gear 52 in the direction, the side wall of the second limiting groove 522 presses the roller 53 to continue to move, when the roller 53 moves to the first limiting groove 512, the roller 13 is pressed under the action of the side walls of the first limiting groove 512 and the second limiting groove 522, so that the second gear 52 is matched with the first gear 51, that is, the first gear 51 is fixed relative to the second gear 52, at this time, the second gear 52 can drive the first gear 51 to rotate through the roller 13, and the rack 6 and the locking piece 2 can be driven to move through the rotation of the first gear 51, so that the automatic opening or closing of the window lock can be realized.
