In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 4, an embodiment of the present invention includes: the utility model provides a high life contact with shock attenuation effect, includes connecting plate 1 and spliced pole 2, has seted up round hole 9 in the centre of connecting plate 1 one side, has seted up first arc hole 10 on the connecting plate 1 of round hole 9 both sides respectively, and round hole 9 communicates with two first arc holes 10 respectively. The middle of one side of the upper surface of the connecting plate 1 is fixed with a round sleeve 4, the aperture of an inner hole of the round sleeve 4 is consistent with that of the round hole 9, and the inner wall of the round sleeve 4 is aligned with that of the round hole 9. The middle of the two sides of the inner wall of the round sleeve 4 is respectively provided with a second arc-shaped hole 11, the two second arc-shaped holes 11 are respectively in one-to-one correspondence with the two first arc-shaped holes 10, and the shapes of the second arc-shaped holes 11 are consistent with the shapes of the first arc-shaped holes 10.

Arc-shaped plates 6 are fixed on two sides of the connecting column 2 respectively, the connecting column 2 penetrates through the round sleeve 4 and the round hole 9, the arc-shaped plates 6 penetrate through the second arc-shaped holes 11 and the first arc-shaped holes 10, and the arc-shaped plates 6 are matched with the second arc-shaped holes 11 and the first arc-shaped holes 10 respectively. The top of spliced pole 2 is fixed with plectane 7, is fixed with spring 5 between plectane 7 lower surface and the upper surface one side of connecting plate 1, and spring 5's elastic coefficient is selected by the technical staff of this specialty and is used according to actual conditions by oneself, and spring 5 overlaps on spliced pole 2 and circle cover 4.
