An electronic card retaining device base structure includes a base for mounting on a predetermined substrate and having a column-like support section and a elongated coupling section transversely connected to a lower end of the support section. The coupling section has a primary retaining end, which is provided at one side closer to the base with a protruded retaining section and can be obliquely extended through an elongated hollow-out slot preformed on the substrate to a lower side of the substrate, and an opposite secondary retaining end also extended through the elongated hollow-out slot. The coupling section is movable horizontally for the secondary retaining end to abut against an end of the elongated hollow-out slot while the protruded retaining section is moved into another end of the elongated hollow-out slot. With the above arrangements, the base structure can be repeatedly quickly mounted on and dismounted from the substrate.

A retaining mechanism includes an open topped seat having a rear inner stop surface and two lateral guide sections; and a sliding clamp member received in the seat and including mating guide sections slidably engaged with the guide sections and a rear curved elastic section having a free end pressing against the inner stop surface. The sliding clamp member further includes a front pressing section having a beveled guide surface on an upper front thereof. The sliding clamp member is movable toward the inner stop surface to elastically deform the curved elastic section when an electronic card is pressed downward against the beveled guide surface, such that the sliding clamp member stores an elastic force and can automatically spring forward to retain the electronic card in place when the electronic card passes over the pressing section. The electronic card can be released simply by pushing the sliding clamp member backward.

A retaining device includes a seat and a swingable clamp member. The seat is repeatedly, quickly and removably connectable to a predetermined substrate and has a stop section transversely extending over an open topped receiving space thereof, and the swingable clamp member has a middle section pivotally connected to the seat to be received in the open topped receiving space. The swingable clamp member has a clamping recess and a push section located at its front and rear ends, respectively; and a recessed section located between the clamping recess and the push section. When an electronic card has a free edge downward pressed against the clamping recess, the clamping recess can swing downward to clamp the free edge of the electronic card thereto. The push section can be pressed to tip up the clamping recess, so that the electronic card is released from the retaining device.

A foldable electronic device includes a first housing part having first magnetic members disposed toward a first inner wall thereof, a second housing part having a second magnetic members disposed toward a second inner wall thereof, at least one hinge connected between the housing parts, and an accessory having third magnetic members disposed toward an attractive wall. In an unfolded state and a transition folded state, the first and third magnetic members are attractive toward each other to hold the accessory on the first housing part. In a fully folded state, the first and second inner walls are close to each other with magnetic attraction of the first and second magnetic members.

An electronic card retaining device includes a seat mounted on a motherboard and a movable retaining member. The seat is provided with a stopper section and a guide section; the movable retaining member has an elastic arm corresponding to the stopper section and a mating guide section for engaging with the guide section. When the movable retaining member is assembled to the seat, the elastic arm can be pressed against the stopper section and elastically deformed; and the guide section and the mating guide section can engage with each other to guide the movable retaining member to elastically displace on the seat relative to an electronic card between a retaining position and a release position. With the above arrangements, the electronic card retaining device so formed is structurally simplified and easily operable for conveniently, securely and elastically retaining or releasing the electronic card to or from the motherboard.
