In the wearable device 10, when the band 200 is not mounted on the case 100, the first engaging member 310 and the second engaging member 370 are in the retracted state, so that the band 200 can be smoothly mounted on the groove 101 of the case 100, and when the rotating member 320 is rotated to the first position after the band 200 is mounted in the groove 101 of the case 100, the first engaging member 310 and the second engaging member 370 protrude out of the band 200, so that the band 200 can be engaged with the case 100. When the watch band 200 needs to be disassembled and the rotating piece 320 is rotated to the second position, the first engaging piece 310 and the second engaging piece 370 retract into the watch band 200, the watch band 200 can be smoothly detached from the watch case 100, the structure can improve the convenience of disassembling and assembling the watch band 200, the occupied space is small, and the light weight and universal design of products are facilitated. The band 200 may have various forms and may be made in a highly versatile form to facilitate the user to replace the band 200. For example, the user can replace the watch band 200 with a more formal one in formal situations and with a more fashionable one in daily use. Of course, it is understood that the second engaging member 370, the second sleeve 381, the third elastic member 383, the second connecting member 220 and the related mounting structure thereof are not necessary and thus may be omitted. For example, a fixed protrusion may be provided on the other side of the watch band 200 opposite to the first engaging element 310, the protrusion may have elasticity, for example, made of silica gel or rubber, the rotating element 320 engages with the watch case 100 at the first position by using the protrusion and the first engaging element 310, and also the watch band 200 can be reliably fixed to the watch case 100, and the watch band 200 can be easily detached from the watch case 100 when the rotating element 320 is at the second position.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
