structure 127 and the second position-limitingstructure 128, the deformation amounts of the firstresilient arm 1321 and thesecond resilience arm 1322 of theelastic part 132 are controllable. Since the deformation amounts of the firstresilient arm 1321 and thesecond resilience arm 1322 are not too large, the firstresilient arm 1321 and thesecond resilience arm 1322 will not be broken. For example, when the external force is applied to thepressing part 131 by the user, thepressing part 131 is correspondingly moved downwardly and the firstresilient arm 1321 and thesecond resilience arm 1322 of theelastic part 132 are subjected to the downward curvy deformation. When the firstresilient arm 1321 and thesecond resilience arm 1322 are respectively contacted with the first position-limitingstructure 127 and the second position-limitingstructure 128, the firstresilient arm 1321 and thesecond resilience arm 1322 are no longer subjected to the downward curvy deformation. - In this embodiment, there is a gap G between the first position-limiting
structure 127 and the firstresilient arm 1321, and there is another gap G between the second position-limitingstructure 128 and thesecond resilience arm 1322. The deformation amounts of the firstresilient arm 1321 and thesecond resilience arm 1322 are determined according to the magnitude of the gap G It is noted that the magnitude of the gap G is not restricted. The magnitude of the gap G may be determined according to the practical requirements. -

Consequently, thesecond positioning structures 1310 of thepressing part 131 are disengaged from thecorresponding positioning structures 1100 of the slidingrail 110. Then, as thepressing part 131 is pushed in the direction away from the expansion port 20 (i.e., along the first axial direction D1) by the user, the slidingpart 121 of thefastening element 12 is correspondingly moved along the slidingrail 110 of the supportingbase 11 in the direction away from theexpansion port 20. As the slidingpart 121 is moved, the lockingpart 122 is correspondingly moved to a position P1. When the external force applied to thepressing part 131 is released, thepressing part 131 is swung upwardly relative to the slidingpart 121 in response to the elastic restoring force of theelastic part 132. Consequently, thesecond positioning structures 1310 of thepressing part 131 are engaged with thepositioning structures 1100 corresponding to the position P1, and the lockingpart 122 is positioned at the position P1. Then, theexpansion card 200 is plugged into theexpansion port 20. - Please refer to

Then, as thepressing part 131 is pushed in the direction toward theexpansion port 20 by the user, the slidingpart 121 of thefastening element 12 is correspondingly moved along the slidingrail 110 in the direction toward theexpansion port 20. As the slidingpart 121 is moved, the lockingpart 122 is correspondingly moved to a position P2 and locked on theexpansion card 200. When the external force applied to thepressing part 131 is released, thesecond positioning structures 1310 of thepressing part 131 are engaged with thepositioning structures 1100 corresponding to the position P2, and the lockingpart 122 is positioned at the position P2.
