Such as, when this chain 10 will be fixed into certain shape, can make to be mutually clamped between the first building block 110 and second building block 210; When to be accepted by this chain 10, can make mutually not engage between the first building block 110 and second building block 210, thus realizing freely rotatable.

With reference to shown in Fig. 1 and Fig. 4, first snap-latch surface the 115, second snap-latch surface the 213, the 3rd snap-latch surface the 216, the 4th snap-latch surface 116 can also be able to be all the combination of curved surface or two kinds of faces for plane, when for plane, the first snap-latch surface 115 can be provided with multiple and be uniformly distributed symmetry. The shape of the first snap-latch surface 115 can be identical with the shape of the 3rd snap-latch surface 216. As shown in Figure 1, first snap-latch surface 115 occurs in pairs and is uniformly distributed, for making be formed between two building blocks multiple angle, first snap-latch surface 115 is evenly distributed with multipair, the first equally distributed logarithm of snap-latch surface 115 is more many, and the kind number of the angle that can be formed between the first building block 110 and second building block 210 is also more many, for instance, make between the first building block 110 and second building block 210 can shape is in 90 �� and the angle of 180 ��, the first snap-latch surface 115 can be evenly distributed with four pairs; Making that the first building block 110 and second building block 210 can shape be at 45 ��, the angle of 90 ��, 135 �� and 180 ��, the first snap-latch surface 115 can be evenly distributed with eight pairs. Multiple first snap-latch surfaces 115 are for can also surround polygonal form, such as can surround triangle, tetragon, pentagon, hexagon etc., the polygonal limit number surrounded is more many, and the optional number of the angle formed between the first building block 110 and second building block 210 when the first snap-latch surface 115 and the second snap-latch surface 213 are mutually clamped is also more many.

First building block 110 may each be, with second building block 210, the square that two ends are circular arc. first protruding 111 and first connecting hole 112 is respectively arranged at the two ends of the first building block 110, second protruding 211 and second connecting hole 212 is respectively arranged at the two ends of second building block 210. it is the first turning end 117 that first building block 110 is provided with one end of the first projection 111, first turning end 117 is provided with outward extending first flange 119, it is the second turning end 118 that first building block 110 is provided with one end of the first connecting hole 112, second turning end 118 is provided with outward extending second flange 120, it is the 3rd turning end that second building block 210 is provided with one end of the second projection 211, 3rd turning end is provided with outward extending third lip 219, it is the 4th turning end that second building block 210 is provided with one end of the second connecting hole 212, 4th turning end is provided with outward extending 4th flange 220, first flange 119 and the second flange 120 press mutually, third lip 219 and the 4th flange 220 press mutually.Above-mentioned mention, when first building block 110 engages with second building block 210, can not rotate around the axis of the first connecting hole 112 or the second connecting hole 212 between first building block 110 and second building block 210, at this moment again through pressing of the first flange 119 and the second flange 120 and pressing of third lip 219 and the 4th flange 220, just the first building block 110 can be locked with second building block 210, thus realizing the fixing of chain 10. When this chain 10 is fixed on the surface of object, object can be played reinforcing and protective effect, it is possible to this chain 10 is fixed into various shape, for instance: it is built into BUILDINGS MODELS, different pattern, shelf etc. No matter whether the first building block 110 engages with second building block 210, and the first flange 119 and the second flange 120 can press mutually, and third lip 219 and the 4th flange 220 also can press mutually.

First flange 119 lays respectively at Different Plane towards the end face of one end that end face and second flange 120 of one end of second building block 210 deviates from second building block 210, and third lip 219 lays respectively at Different Plane towards the end face of one end that end face and the 4th flange 220 of one end of the first building block 110 deviates from the first building block 110.

The distance of the end face place plane of one end of second building block 210 of first flange 119 deviating from towards the end face place plane of one end of second building block 210 to the second flange 120 deviates from the distance of the end face place plane of one end of the first building block 110 equal to third lip 219 towards the end face place plane of one end of the first building block 110 to the 4th flange 220, and the first flange 119 deviates from end face place plane in opposite direction that the direction of the end face place plane of one end of second building block 210 and the third lip 219 end face place plane towards one end of the first building block 110 deviates from one end of the first building block 110 to the 4th flange 220 towards the end face place plane of one end of second building block 210 to the second flange 120. So when the surface multi-turn that this chain 10 is wound on object is wrapped in object, the chain 10 of multi-turn can stagger mutually without being overlapped mutually, because easily taking up room when the chain of multi-turn 10 is overlapped mutually. And the chain 10 of multi-turn mutually stagger can be smooth the surface being wrapped in object.

Such effect is, when the first building block 110 and second building block 210 are all in plane symmetry, the first flange 119 deviates from the direction of the end face place plane of one end of second building block 210 and the third lip 219 end face place plane towards one end of the first building block 110 and deviates from the key that end face place plane in opposite direction of one end of the first building block 110 is difference the first building block 110 and second building block 210 to the 4th flange 220 towards the end face place plane of one end of second building block 210 to the second flange 120. that is, this can make the first building block 110 and second building block 210 be two different objects. such as, when the first building block 110 and second building block 210 are all in plane symmetry, and first flange 119 deviate from towards the end face place plane of one end of second building block 210 to the second flange 120 direction and the third lip 219 of end face place plane of one end of second building block 210 deviate from towards the end face place plane of one end of the first building block 110 to the 4th flange 220 direction of end face place plane of one end of the first building block 110 identical time, first building block 110 can be same object with second building block 210, namely at this moment to manufacture the first building block 110 and have only to out a kind of mould with second building block 210.But in the present embodiment, the first building block 110 is two different objects from second building block 210, namely at this moment to manufacture the first building block 110 need at least to open two kinds of moulds with second building block 210 can.
