Sphenocephaly 44 oblique cuttings of push rod 40 are gone into the breach 25 of gland 20, set level in the horizontal concrete chute 23 of gland 20;

In the semicircle shaft hole 13 of the rotating shaft 31 horizontally mounted bases 10 of single armed draw ring 30, cam 32 is put into the sinking cavity 14 of base 10;

Spring 50 1 ends are enclosed within on the cylinder boss 42 of push rod 40, the other end be pressed on gland 20 square protruding 24 on, form an assembly, this assembly integral installation is to base 10, the threaded hole 21 of gland 20 cooperates with the threaded hole 11 of base, connects by screw.

Two, parts

1, base 10

As Fig. 1,2, base 10 is a kind of rectangle body of castings that comprise termination and negative, and the termination is provided with a pair of threaded hole 11, LC type connector port one 2, a pair of semicircle shaft hole 13 and a sinking cavity 14;

The semicircle shaft hole 22 of semicircle shaft hole 13 and gland 20 forms the cavity that holds single armed draw ring rotating shaft 31, and sinking cavity 14 is used to hold single armed draw ring cam 32.

2, gland 20

As Fig. 3 .1,3.2, gland 20 is a kind of rectangle body of castings, and the inner face of gland 20 is provided with and the threaded hole 11 corresponding a pair of threaded holes 21 of base 10, a pair of semicircle shaft hole 22, horizontal concrete chute 23 and one square protruding 24; Outside behind the gland 20 is provided with a breach 25 and the module tapered end 26 to upper process.

Horizontal concrete chute 23 and breach 25 are used to hold push rod 40, square protruding 24 form the cavity that holds spring 50 with push rod rectangular cavity 41, the module tapered end 26 that raises up is used for cooperating with the elastic collet and the lockhole of cage with push rod sphenocephaly 44, forms locking and released state.

3, the single armed draw ring 30

As Fig. 4, single armed draw ring 30 is a kind of L shaped body of castings, and the one side of the L shaped body of casting is connected with rotating shaft 31 and cam 32, and the another side sign of the L shaped body of casting has the arrow 33 of pulling direction and is provided with anti-skidding lines 34.
