stress surfaces along a stretching direction, that is, a first stress surface 31 and
a second stress surface 32, wherein the first stress surface 31 and the second stress
surface 32 on which a first placement end 321 and a second placement end 322 are designed

elastic fastener 42 and the second elastic fastener 43.
[0021] The bottom 41 of the spring-loaded locating piece 4 is welded or stuck on one of
the shaft levers 2 so that the spring-loaded locating piece 4 is fixed on the shaft
lever 2; both the first elastic fastener 42 and the second elastic fastener 43 of
the spring-loaded locating pieces 4 face the top bed surface 12.

the second stress surface 32 are positioned at two adjacent shaft levers 2 so that
the first placement end 321 of one spring 3 and the second placement end 322 of the
other spring 3 occupy the clamping space 44 developed by the first elastic fastener
42 and the second elastic fastener 43 of the spring-loaded locating piece 4 and are
separated by the spacer block 411 for no entanglement of any two springs 3. Moreover,
each spring 3 is fixed on two adjacent shaft levers 2 and makes its hollow space 33
correspond to the spacing 21 developed by the two adjacent shaft levers 2 when the
fastening block 421 of the first elastic fastener 42 and the fastening block 431 of
the second elastic fastener 43 clamp the spring coil of one spring 3 and the spring
coil of the other spring 3, respectively. As shown in FIG. 7, each of minor springs
5 hung in the hollow spaces 33 of the springs 3 is freely activated through the spacing
21 between two adjacent shaft levers 2.

spring 3 are directly stuck on surfaces of two adjacent shaft levers 2 and the second
stress surface 32 of the spring 3 is fixed on surfaces of the shaft levers 2.

coating 6 which is made of paper, woven or non-woven fabric, or another fabric material
and penetrated by the first elastic fasteners 42 and the second elastic fasteners
43 of the spring-loaded locating pieces 4 before the first elastic fasteners 42 and
the second elastic fasteners 43 are coupled with the springs 3; the second stress
surfaces 32 of the springs 3 can be stuck on the shaft levers 2 with viscose which
is taken as the spring-loaded locating pieces 4' permeating onto the second stress
surfaces 32 of the springs 3 through the external coating 6; the spring-loaded locating
