  • Patent number: 10389967
    Abstract: A removable attachment structure includes a movable module and a latching module. The movable module includes a first receiving groove. The latching module includes a first mounting portion and a latching subassembly on the first mounting portion. One end of the latching subassembly and the first mounting portion defines an entrance, the entrance allows the movable module to enter into or come out of the latching module. For latching, the movable module vertically enters into the entrance and is driven to the latching subassembly until the latching subassembly is completely received in the first receiving groove. For unlatching, the movable module is driven in opposite direction until the latching subassembly is disengaged from the latching part, thereby disengaging the movable module from the entrance.
