The preset distance is 0.5 times the distance between the proximal ends of the two side fixing arms 22. The proximal end is an end of the side fixing arm 22 close to the connecting structure 21.

[0082] Preferably, the two side fixing arms 22 of the same embracing fixing member 2 are parallel to each other.

[0083] Preferably, in the same embracing fixing member 2, there is at least one side fixing arm 22 with an angle of 90 degrees between the side fixing arm 22 and the connecting structure 21.

Obviously, A is greater than 0.5 times B.
