Abstract:
A pre-assembled structure of a fastening device and a locking structure. The pre-assembled structure of the fastening device comprises a locking member (10), a guide cap (20), and an anchoring member (30). The locking member (10) comprises an assembly portion (11) and an insertion portion (12). The assembly portion (11) is connected to the insertion portion (12) and is fixed to the relative position of the guide cap (20). The insertion portion (12) comprises a body (121), a first locking groove (122), a second locking groove (123), and an expansion portion (124). A recess (125) is provided between the expansion portion (124) and the assembly portion (11). The guide cap (20) comprises a guide portion (21) and an end cap (22). The anchoring member (30) comprises a clamping disc (31), two locking portions (32), and two holding portions (33). The locking portion (32) comprises a hoop portion (321). The end cap (22) is opposite to the end of the locking portion (32). When the fastening device is in the locking structure, the diameter of the circumcircle at the joint between the locking portion and the holding portion and the clamping disc is larger than the diameter of a through hole. According to the fastening device, damage caused when the fastening device is inserted can be avoided, such that the yield of the fastening device during assembly is improved.
