the second convex-column chassis (142), the second convex-column chassis (142) is formed at the top end of the second limiting column (141), and the diameter of the second convex-column chassis (142) is larger than that of the second limiting column (141);

and, the second through hole (5) comprises:

a second chassis through hole (51), the second chassis through hole (51) for the second stud chassis (142) to pass through;

the second limiting column through hole (52), the second limiting column through hole (52) is communicated with the top of the second chassis through hole (51), the diameter of the second limiting column through hole (52) corresponds to that of the second limiting column (141), and the second convex column (14) extends into the rear shell (2) from the second chassis through hole (51) and is limited in the second limiting column through hole (52) through the second limiting column (141).

11. The bracket assembly of claim 10, wherein the second restraint post (141) has a pair of second restraint post sidewalls (1411) extending in a vertical direction, a spacing between the pair of second restraint post sidewalls (1411) being smaller than a diameter of the second restraint post (141);

the diameter of the second limiting column through hole (52) corresponds to the distance between the pair of second limiting column side walls (1411) so as to limit the axial rotation of the second limiting column (141) in the second limiting column through hole (52).
