LATCHING STRUCTURE

A spring-loaded rounded latching structure includes a main body and a back cover. The main body defines a groove bound by a bottom wall and a sidewall. The bottom wall defines a slot and includes a resisting portion. The side wall includes a first snap. The main body includes a button. The button includes a pushing member. The back cover defines a second slot and includes a second snap and a stopping block. The back cover is slidable relative to the main body along the groove defined in the main body. The first snap is snapped in the second slot. The second snap is snapped in the first slot. The resisting portion resists the stopping portion to limit a sliding movement of the back cover. The resisting portion is released from the stopping portion within the groove by the pushing member.
