Referring to Figures 1 to 7 As shown,

[0054] The fastener 30 is provided with a groove arranged along the first direction;

[0055] The adjusting seat 40 is connected to a first bolt 42 with a first nut 43. The first bolt 42 is inserted into the groove. By moving the first bolt 42 within the groove, the adjusting seat 40 moves relative to the fastener 30 along the first direction. The adjusting seat 40 and the fastener 30 are fixedly connected by screwing the first nut 43 onto the first bolt 42.

[0056] In this embodiment, the diameter of the groove is adapted to that of the first bolt 42.
