Connection is there are four stairstepping step on week, and the angle between two neighboring stairstepping step is 90 °, two neighboring stairstepping step
Between be equipped with a boss being connect with the excircle of upper disk, altogether there are four boss, adjacent boss and stairstepping step
Between angle be 45 °；Boss is equipped with boss threaded hole, and stairstepping step is made of two steps, and each step all has
Step plane；Upper disk is set there are four circular hole, and the angle between two neighboring circular hole is 90 °.
Preferably, the outer circle of circular hole and wire spool cylinder is tangent；The quantity that casing installs threaded hole is four, four casings
Installation threaded hole is uniformly distributed centered on the axle center of wire spool cylinder.
Preferably, the length of stairstepping step is 10mm, and the length of boss is 10mm；First step of stairstepping step
Height be 1.5mm, the height 1mm of second step, the height of boss is 2.5mm.
The invention has the advantages that being fixedly connected for top and the bottom and system chassis has been fully taken into account, on upper disk
The mountable minor flaps in portion can place optical coupling interface unit in minor flaps, and four stairstepping steps can also place optical fiber end
Head.Entire wire spool install optical fiber and in system after, with being completely embedded of system bound fraction and device, it is solid, can
It leans on.
