In an embodiment, opposite ends of the elastic member are respectively connected to the first clamping member 311 and the second clamping member 312. When the clamping component 310 leaves the clamping groove 210 (or enters the watch band 100), the elastic member accumulates elastic force. When the elastic member releases the elastic force, the elastic member can push the clamping component 310 into the clamping groove 210 (or Extend the strap 100).

In the above-mentioned wearable device 10, the clamping component 310 is in a state of protruding out of the watchband 100 in a natural state, and the clamping component 310 cannot be engaged with the clamping groove 210. If it is necessary to install the watchband 100 on the dial 200 , First move the paddle 340 in the first direction to drive the movable part 320 to move in the first direction, and then the movable part 320 drives the clamping assembly 310 into the watchband 100 through the transmission mechanism 330. At this time, the elastic pieces gather in the opposite direction Elastic force, then align the clamping component 310 with the clamping groove 210, release the paddle 340, and the clamping component 310 will move into the clamping groove 210 under the action of the elastic member, thereby realizing the assembly of the watchband 100 and the dial 200 . In the same way, if it is necessary to detach the watch band 100 from the dial 200, repeat the above operations, which will not be repeated here.

The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, All should be considered as the scope of this specification.
