When the turntable 3 rotates, the moving paths of the two protruding blocks 42 pass through the same circle, and the positions of the two protruding blocks 42 have a phase difference of 90 degrees, namely, the two protruding blocks 42 are circumferentially arranged on the turntable 3 relative to the turntable 3, and an included angle of 90 degrees is formed between the axes of the two protruding blocks 42 extending to the circle center of the turntable 3. Of course, when changing different turntables 3, the circumferential transmission mechanisms 31 thereon are also different to limit the rotation angles of the turntables 3, so that the switching of different switch lock modes can be realized by changing different turntables 3. In this embodiment, the rotary disk 3 provided with two protrusions 42 can realize a switching lock mode of rotating forward and backward 180 °. In specific implementation, various turntables 3 can be replaced to realize switching of different unlocking modes, such as turntables with three lugs 42 and four lugs 42. Other turntables 3 with more lugs 42 arranged along the circumference of the turntables 3 relative to the turntables 3 can be replaced, at this time, the included angle formed between the axes of the lugs 42 extending to the circle center of the turntables 3 can be changed, for example, 30 degrees and 60 degrees, and the circumferential transmission mechanism 31 on the turntables 3 also needs to be correspondingly changed in structure. The rotary disc 3 with the structure in this embodiment is detachably connected to the outer side of the housing 100, so that when a user needs to change the switch lock mode, the user only needs to change the rotary disc 3, and then reset the corresponding driving parameters of the external main control circuit to realize the switch locks in different modes. Therefore, the turntables 3 of various types can be produced in batches independently aiming at the turntables 3, and then the turntables 3 are sold together with the intelligent lock, so that when a user wants to change the switch lock mode, the user only needs to change the turntables 3 which want to realize the corresponding effect, and then reset the corresponding driving parameters of the external main control circuit.

The first connecting shaft 11 passes through the second through hole 32 on the rotary table 3 from bottom to top and then passes through the third through hole 3121 on the dial block 312. In particular, the second through hole 32 is larger than the third through hole 3121, so that the first connection shaft 11 is connected to the third through hole 3121 after passing through the second through hole 32. The shape of the third through hole 3121 is adapted to the shape of the upper end of the first connection shaft 11, so as to fixedly sleeve the dial block 312 on the first connection shaft 11 and limit and clamp the dial block. The dial 312 can rotate back and forth left and right in the limit groove 311. A rotation virtual position 313 is arranged between the shifting block 312 and the limiting groove 311 so that the rotary table 3 and the shifting block 312 rotate synchronously after rotating in place. In specific implementation, a bearing is disposed between the first gear 12 and the first connecting shaft 11, the first gear 12 rotates to drive the turntable 3 to rotate, at this time, the first connecting shaft 11 and the dial block 312 do not rotate, when the turntable 3 rotates in place, that is, when the dial block 312 abuts against the left end or the right end of the limiting slot 311, the turntable 3 drives the dial block 312 to synchronously rotate, so as to drive the first connecting shaft 11 to synchronously rotate, and at this time, the first connecting shaft 11 rotates to idle in the second through hole 32. Thus, the switch lock of the intelligent lock can be realized. The provision of the rotary dummy bit 313 facilitates different ways of switching the lock. In specific implementation, the sizes of the shifting block 312 and the rotating virtual position 313 arranged on the turntables 3 of different models are different. The length of the limiting groove 311 can be set according to the unlocking mode to be achieved. Thus, the switching of different switch lock modes is realized. In addition, the setting of rotating the virtual position 313, when the user rotates the switch knob manually to drive the shifting block 312 to rotate, the shifting block 312 can not immediately contact the two ends of the limiting groove 311, so that the mechanical connection between the gear transmission assemblies 1 can not influence the hand feeling of the user when the user rotates the switch knob, thereby improving the comfort of the user during use.
