According to the present invention, the feature that this purpose is included in the characteristic by claim 1 is realized,
What the further feature preferred version of the present invention was included in being characterised by each dependent claims
Feature.Additionally, according to a further aspect of the present invention, chain link clamping risk can reduce.
By the measure for teat tip to the distance of relative flat's lower limb of claim 1,
The width of teat and section can reduce, and which increase the Semicircular arched of adjacent link adjacent with described
The free space in chain link that chain link is connected, so as to provide bigger for the two of adjacent link arches
Range of movement.To this alternately or complementally, the flat leg of chain link exists two edges
It is round and smooth at inner side, wherein circularity (rounding) is preferably interior in the interval of 19 to 26mm,
This also makes round and smooth chain link increase range of movement compared with flat chain link, and both measures itself or
Clamping risk has been substantially eliminated when particularly combining.In addition, the stability increase of chain link.
The measure of dependent claims is accordingly worked, and these dependent claims are focused in teat
Tip and relative flat's lower limb between preferred distance, the more compact area of the circularity at the edge of flat leg,
And the sectional dimension and zip length of Semicircular arched.These measures also with the purpose and according to
The solution of claim 1 is related, and increases the stability and range of movement of chain link.
