The specific embodiment

See Fig. 1 a, 1b, embodiment one structure is as follows: the two ends spanner 1 of fork spanner shape trigger piece 5 is pulled in the mouth, the removable sub-spanner 4 of setting-in, the mouth of pulling of spanner 1 can be straight-through shape (as the mouth of pulling of figure middle and upper part), also can be provided with positioning boss 6 (as the mouth of pulling of figure middle and lower part) at an end of pulling mouth.Between spanner 1 and sub-spanner 4 the elasticity Fastener is set, its structure is as follows: assembling spring 3 and card pearl 2 on spanner 1 make sub-spanner 4 better fixing.

See Fig. 2 a, 2b, 2c, embodiment two structures are as follows: an end is the double offset ring spanner spanner, and the other end is the box spanner spanner.Fig. 2 b is the left view of Fig. 2 a, and Fig. 2 c is the A-A profile of Fig. 2 a.The elasticity Fastener is for embedding the elastic spring 7 on the spanner inner edge.Elastic spring can be integral body, and (seeing Fig. 2 c profile) also can be split, (seeing the top spanner schematic diagram of Fig. 2 a).

See Fig. 3 a, b, sub-spanner cross sectional shape is a regular polygon, and the spanner periphery of regular polygon is an integral body.

See Fig. 4 a, be the disconnection shape on the periphery of polygon spanner, see Fig. 4 b, the peripheral gap of the sub-spanner of polygon can be on polygonal angle.See Fig. 4 c, d, the periphery of polygon spanner disconnects can be damaged for a limit or two limits.

See Fig. 4 e, f and Fig. 4 g, the mouth of pulling of sub-spanner can be straight-through shape, also can be provided with positioning boss 8 at an end of pulling mouth.The positioning boss 8 of sub-spanner 4 plays positioning action.

See Fig. 5, the structure of embodiment three is as follows: the two ends spanner 1 of double offset ring spanner shape trigger piece 5 is pulled in the mouth, the removable sub-spanner 4 of setting-in, and the elasticity Fastener that assembling spring 3 and card pearl 2 constitute on the spanner 1 is perhaps assembled elastic spring 7 Fasteners.The mouth of pulling of spanner 1 can be straight-through shape (as the mouth of pulling of figure middle and upper part), also can be provided with positioning boss 6 (as the mouth of pulling of figure middle and lower part) at an end of pulling mouth.

See Fig. 6, Fig. 7, Fig. 8, the structure of embodiment four is as follows: an end spanner 1 of box spanner trigger piece 5 is pulled in the mouth, the removable sub-spanner 4 of setting-in.The elasticity Fastener that assembling spring and card pearl constitute on the spanner 1 is perhaps assembled the elastic spring Fastener.Trigger piece in the present embodiment can adopt existing crank (shown in Figure 6), staight shank (shown in Figure 7), slide a handle (shown in Figure 8) etc.
