Detailed Description

As shown in fig. 1 and 2, the technical scheme of the utility model is an anti-vibration hammer, which comprises a wire clamp main body 1, a steel strand 2, a long hammer head 3 and a short hammer head 4, the steel strand 2 is sequentially provided with a long hammerhead 2, a wire clamp main body 1 and a short hammerhead 4 from left to right, the lower end of the wire clamp main body 1 is fixed on the steel strand 2, the wire clamp main body 1 is provided with a lead 6 through a pressing plate 5, the upper end of the wire clamp main body 1 is provided with a groove 7 for the lead 6 to pass through, a threaded blind hole is arranged on the wire clamp main body 1 near the groove 7, a round hole corresponding to the threaded blind hole is arranged on the pressing plate 5, a bolt 9 passes through the nut and the round hole, and the screw thread is established in the screw thread blind hole, and the clamp plate 5 inboard encloses into the wire with recess 7 and places the region, long hammerhead 3 in fix one side at steel strand wires 2 through first sleeve pipe 10, short hammerhead 4 fixes the opposite side at steel strand wires 2 through second sleeve pipe 8.

In the embodiment, the steel strand 2 is a galvanized steel strand, and the length of the steel strand 2 is 413-417 mm.

In this embodiment, the lower end of the wire clamp body 1 is provided with a through hole, and the steel strand 3 passes through the through hole and is fixed in the through hole.

In this embodiment, a reinforcing gasket 11 is disposed between the bolt 9 and the circular hole.
