摘要:
A fastening unit (4) includes a hole-defining unit and a fastening component (41). The hole-defining unit is adapted to be provided in a surface of a first body (2), defines a fastener hole (42), and is provided with at least one first engaging part (421, 421', 421'', 421a). The fastening component (41) is adapted to be fixed to a second body (3), has a post body (411) provided with a second engaging part (414, 414', 414'', 414a) equal in number to and having a structure complementing the first engaging part (421, 421', 421'', 421a), and at least one surrounding member (412, 412'). When the fastening component (41) is extended in an axial direction into the fastener hole (42) to interconnect the first and second bodies (2, 3), the first and second engaging parts cooperate so that the fastening component (41) is prevented from rotating in the fastener hole (42).
摘要:
A fastening unit includes a fastening component (41) and a hole-defining unit. The fastening component (41) is adapted to be fixed to a first body (3), and includes a cylindrical post body (411) and at least one surrounding member (412). The post body (411) extends along a post axis (D1). The surrounding member (412) surrounds and is fixed to an outer post surface of the post body (411), and a portion of lines (D2) tangent to points on an outermost perimeter of the surrounding member (412) are at non-90° angles (α) with respect to the post axis (D1). The hole-defining unit is adapted to be provided in a surface of a second body (2), and defines a fastener hole (42) that fittingly receives the fastening component (41) for interconnecting the first and second bodies (3,2).
