Embodiment Construction
[0011] figure 1 What is shown is a structure with only 4 crests forming two bosses, and of course a structure larger than two bosses can also be designed according to requirements.
[0012] As shown in the figure: there is a wave-shaped positioning support piece 9 with a cross-section, based on the annular flat plate 7 at the edge, the upper surface of the annular flat plate 7 is extended and arched upwards, forming the first crest 3, and the face of the first crest 3 is inclined downward. Extending to form the first wave trough 4, the surface of the first wave trough 4 is extended upwards to form the second wave peak 3', and the second wave peak 3' is extended downward to form the second wave trough 4'; so repeated, several wave peaks and wave troughs can be formed . The first crest 3 and the second crest 3' form the first boss 1, the surface of the second trough 4' extends obliquely upwards to form a third crest 5, and the face of the third crest 5 extends downward to form ...
