One self-locking ring 1, there is a taper anchor ring 18 its left end inside, and self-locking ring 1 its central bore 21,19 is formed a stepped inwall, and forms a shoulder 20.This self-locking ring 1 is to be slidingly fitted by the small end cylindrical 22 of its endoporus 21 with left shell 8.After this, there is a snap ring 2 to embed in the annular groove 11 of left shell 8; Other has 6 steel balls 3 to be positioned in the taper hole 13, is pressed on the taper hole face 13 by hole surface 21 within the self-locking ring 1;

One spring 4, it is enclosed within on the small end cylindrical 22 of described left shell, between shoulder 20 and 16;

One seal ring 6, it is placed in the annular groove 23 of left shell 8, and drive fit mutual with it, forms the labyrinth-like sealing;

One piston 5, its head 24 have 4 along the uniform through flow hole 30 of its cylindrical; Piston 5 can be in seal ring 6 endoporus 25 move left and right; When joint 10a breaks away from piston crown, because the impacting force of spring 7 is located on the end face 26 of seal ring 6 piston seat 27; At this moment, the through flow hole 30 of piston crown does not just play the circulation effect, and promptly connector is in disconnection state shown in Figure 1, and

One right casing 9, its left end has outside thread 32, matches with screw 15 within the left shell 8 by it, right casing 9 and left shell 8 is linked be one.The middle part of right casing 9 is to make the hexagon nut shape, tightens usefulness during as the installation connector.The right-hand member of right casing 9 has outside thread 33, and its endoporus is a shoulder hole, forms a shoulder 34.Spring 7 one ends are enclosed within on the piston small end 29, and are located between the shoulder 34 of piston land 28 and right casing.Its left end inner hole wall has a concave circular arc shape ring-type to expand chute 31.
