    Patent number: 9088138
    Abstract: A mounting device for securing an electronic component includes a support base, a fixing board and a latching member. The support base includes a first track defining a first sliding direction and a second track defining a second sliding direction that intersects with the first sliding direction. The fixing board is connected to the electronic component and capable of sliding along the first track with the electronic component. The latching member is capable of sliding along the second track and includes an elastic element. The elastic element is configured to position the latching member at a desired position with respect to the support base and to provide a resilient force to the latching member, allowing the latching member to push the fixing board to cause the fixing board to abut against the support base, thereby limiting a movement of the fixing board along the first track.
