The elastic damping element 10 includes a lead core and a steel spring surrounding the lead core; the lead core has a circular cross-section with a diameter of 5mm-10mm.

The cross-section of the sliding rod 11 is a circular cross-section, so as to minimize the friction between the sliding rod 11 and surrounding components during the sliding process. A sliding groove corresponding to the sliding rod 11 is provided on the contact surface of the rib 8 for contact with the sliding rod 11; The relative displacement causes the sliding rod 11 to slide in the sliding groove.

The elastic member is not in contact with the support plate 7 and the rib plate 8 to ensure that the spring and the lead core can be stretched and compressed freely.

The pipe bus clamp 12 includes two parallel and opposite semicircular upper clamping plates and a semicircular lower clamping seat connected to the upper clamping plates by bolts, and the bolts are arranged at the front and rear ends of each of the upper clamping plates The bottom of the lower clamping seat is provided with a connection end; the connecting ends are two splints parallel to each other and perpendicular to the bottom of the lower clamping seat; One end of the rod 11 is flexibly connected by a nut so that the sliding rod 11 can slide freely. One of the splints is provided with a fitting drain wire 13 on the outside.
