Fastening member and device having the same

摘要

A fastening member for fastening and unfastening at least two panel members includes first and second elastic arms. One panel member has a first surface. The other panel member has a second surface facing away from the first surface. Each panel member has a fixed through hole having at least a portion with a width (P1). Each elastic arm has first and second end edges respectively proximate to and relatively distal from the first surface. The first end edge has a width larger than the width (P1). A limiting arm extends from the first end edge of the first elastic arm, and includes a limiting portion that can extend through the fixed through holes of the panel members or move away from the second elastic arm when the elastic arms are pressed or released, respectively.

1. A fastening member for fastening and unfastening at least two panel members that are disposed one over the other, one of the panel members having a first surface, the other one of the panel members having a second surface facing away from the first surface, each of the panel members further having a fixed through hole, the fixed through hole having at least a portion with a width (P1) extending in a first direction parallel to a width of each panel member, said fastening member comprising:
first and second elastic arms spaced apart from each other in an elastic direction that is perpendicular to the first direction, each of said first and second elastic arms having a first end edge for being proximate to the first surface, and a second end edge for being relatively distal from the first surface, said first end edge having a width larger than the width (P1); a connecting portion connected between said second end edges of said first and second elastic arms to allow said first and second elastic arms to move toward or away from each other along the elastic direction; a limiting arm extending from said first end edge of said first elastic arm and including
a neck portion proximate to said first end edge and having a width (W1) equal to or slightly less than the width (P1), anda limiting portion extending from one end of said neck portion distal from said first end edge and having a projected area larger than that of said neck portion; and a fixed arm extending from said first end edge of said second elastic arm, said fixed arm including a fixed portion extending in a direction away from said limiting arm for fixed connection with the first surface; wherein, when said first and second elastic arms are pressed to move said limiting arm close to said second elastic arm, said limiting portion can extend through the fixed through holes of the panel members and out of the second surface; and when said first and second elastic arms are released from being pressed, said limiting arm moves away from said second elastic arm, a surface of said limiting portion that is proximate to said neck portion abuts against the second surface, and said neck portion abuts against peripheral edges of the fixed through holes in the elastic direction.
