The hook component includes a central guide bar and two elastic hooks disposed on either side of the guide bar. The outer ends of the elastic hooks are provided with hook-shaped protrusions. An elastic locking gap is provided between the elastic hooks and the guide bar. When the hook component is inserted into the card interface, the hook-shaped protrusion of the elastic hook engages the lower end of the card interface. When the two elastic hooks are pressed against each other, the hook component and the card interface disengage from each other. The elastic hook includes a vertical elastic plate and the hook-shaped protrusion disposed at the end of the elastic plate. When the elastic hook and the card interface engage with each other, the elastic plate elastically conforms to the inner wall of the card interface. This hook component structure enables flexible assembly and disassembly of functional modules such as the cleaning assembly and the card connector, facilitating use.
