When the peg 231 is toggled to make the peg 231 move away from the end 205 of the strap body 210, the two eject pins 232 move towards each other and retract into the strap body 210, and the spring 233 is compressed. When the force applied to the peg 231 is released, the spring 233 in the compressed state drives the two eject pins 232 to extend out of the strap body 210, and the first sheet 241 and the second sheet 242 rotate as the connectors 2322 move along the first slot 2431 and the second slot 2432, and the included angle between the two increases, driving the peg 231 to move in the peg-sliding hole 221 towards the end 205 of the strap body 210, that is, towards the watch body 100. Until the two insertion pins 2321 are inserted into the installation holes 112 respectively to make the strap 200 installed onto the watch body 100, the peg 231 stops moving in the peg-sliding hole 221 and stays at the end of the peg-sliding hole 221 close to the watch body 100.

In the wearable device 10 of the present disclosure, the peg 231 is exposed outside the strap body 210 and is connected to ends of the first sheet 241 and the second sheet 242. The two eject pins 232 pass through the first slot 2431 and the second slot 2432 of the fixing sheet 243 and are respectively connected to the other ends of the first sheet 241 and the second sheet 242, and a spring 233 is provided between the two eject pins 232. By moving the peg 231, the two eject pins 232 can be driven to extend out or retract into the strap body 210. In the state where the two eject pins 232 are retracted into the strap body 210, the end 205 of the strap 200 can be placed in the installation groove 110; and when the force on the peg 231 is released, and the two eject pins 232 extend out of the strap body 210 under the action of the spring 233 and snap into the installation groove 110, so that the strap 200 is installed onto the watch body 100. When the peg 231 is moved again to retract the two eject pins 232 into the strap body 210, the strap 200 can be detached from the watch body 100. The above structure is relatively simple and convenient for users to exert force. Therefore, it is possible to avoid the operation of thin spring bars. In this way, the convenience in operation can be improved and the attachment and detachment between the strap 200 and the watch body 100 becomes easy. For example, with the wearable device 10 having the above-mentioned structure, a user can conveniently change different straps 200 of different styles depending on usage scenarios. The watch body 100 is not provided with protruding lugs for connecting the strap 200. Instead, the installation groove 110 is used to allow the strap 200 to be inserted into the watch body 100, thereby reducing the gap between the strap 200 and the watch body 100 and improving the aesthetics of the wearable device 10.
