[Detailed ways]

As shown in Figures 1 to 3, a clutch structure of an electronic mortice lock includes a clutch body 1, a first clutch piece 2 and a second clutch piece 3 matched with it, and the clutch body 1 is provided with a through hole 101, The first clutch plate 2, the second clutch plate 3 are respectively provided with fitting parts 201, 301 that can be inserted into the through hole 101 and can rotate around its axis; Counterbore 202, 302 is arranged, and one of the two clutch plates is connected with the clutch body 1 through the screw 5 as a whole.

The matching portion 201 on the first clutch plate 2 and the matching portion 301 on the second clutch plate 3 are stacked together in a mating manner; Gaps 2010, 3010. The clutch body 1 is provided with a pin hole 103 connected with the through hole 101, a step 107 is provided in the pin hole 103, and the outer end of the pin hole 103 is fixedly connected with a guide piece 6, and the guide piece 6 is provided with a guide hole 601; a clutch pin 4, one end is placed in the latch hole 103, and a snap ring 401 is also provided on the clutch pin 4, and a return spring 7 is sleeved on the clutch pin 4 between the snap ring 401 and the step 107, and the other end of the clutch pin 4 is placed in the latch hole 103 outside.

As shown in Figure 4, the clutch structure 1 of the present utility model is installed in the lock body 8 of the electronic mortise lock, and the two clutch plates can be connected with the handle inside and outside the door, and the clutch body 1 is provided with a fork 104, when the clutch body 1 When rotating, pulling fork 104 can drive connecting rod 12 to rotate, and connecting rod 12 drives square tongue 11 to move again, and when continuing to rotate, pulling block 203 on the clutch plate 2 can drive oblique tongue 13 to move, thereby realizes unblanking.
