The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As Fig. 1-shown in Figure 5, the utility model comprises elastic bottom plate 1, joint 2, windscreen wiper sheet 3, left and right sheath 4 and left and right footmuff 5.
Elastic bottom plate 1 is provided with criss-cross through hole 11, before horizontal through hole 111 in the criss-cross through hole 11 and the elastic bottom plate 1, back side edge is parallel, before vertical through hole 112 in the criss-cross through hole 11 and the elastic bottom plate 11, back side edge is vertical, be respectively equipped with two first extensions 21 that extend on 2 two relative sides of joint downwards, be provided with second extension 22 of downward extension between two first extensions 21 on the same side, the end of first bending part 21 is provided with first Access Division 211 of square bent plate shape, the horizontal part 212 of first Access Division 211 stretches out, can make the volume of joint littler like this, the end of the vertical component effect 213 of the first Access Division 211 5-20 degree that slopes inwardly, the end 221 outward-dipping 5-20 degree of second bending part 22, second extension 22 is inserted in the vertical through hole 112 in the criss-cross through hole 11, the bottom surface that elastic bottom plate 1 is blocked in its end 221 and outside bending, the bottom surface that elastic bottom plate 1 is blocked in the inside respectively bending of the vertical component effect 213 of first extension 21.
The end of the vertical component effect 213 of the first Access Division 211 5-20 degree that slopes inwardly, the end 221 outward-dipping 5-20 degree of second bending part 22, can play the effect of joint 2 and elastic bottom plate 1 working fastening, be installed on the elastic bottom plate 1 before on the compression machine first, second extension being compressed at joint 2 and can not come off easily.
