[0055] It is worth noting that the smart device in this embodiment may be a smart meter.

[0056] When using the battery compartment fixing device of this embodiment, first, install the sealing ring 105 into the sealing groove 1041 of the battery compartment 1; then, insert the button battery 4 according to the positive electrode mark 10211 on the positive electrode clamping part 1021 of the battery compartment 1, and the button battery 4 is firmly fixed by the positive electrode clamping part 1021, the negative electrode clamping part 1022 and the arc structure 1011, and does not fall out when the force is less than the critical point; finally, when installing the battery compartment 1, insert the battery compartment 1 into the battery compartment 1 through the handle part 103. The button battery 4 is inserted into the terminal box 2 and electrically connected with the positive spring piece 301 and the negative spring piece 302 on the main board 3. The battery compartment 1 and the limit piece 204 form an inverted fit, so that the battery compartment 1 does not fall out of the terminal box 2 when the force is less than the critical point. When the button battery 4 needs to be replaced, it is only necessary to apply a force greater than the critical point to the handle 103 to make the battery compartment 1 separate from the terminal box 2, and then apply a force greater than the critical point to the button battery 4 to make the button battery 4 fall out of the battery compartment 1, thereby completing the replacement of the button battery 4.
