Novel shockproof hammer

2008 
The utility model discloses a novel damper which comprises a wire clamp, a steel stranded wire and two damper heads; the wire clamp is fixed in the middle part of the steel stranded wire; the two ends of the steel stranded wire are fixedly provided with the damper heads which are divided into a large damper head and a small damper head; the weight of the large damper head is 1.2 to 2 times of that of the small damper head. The distance from the gravity center of the large damper head to the center of the wire clamp is longer by 0 to 100mm than the distance from the gravity center of the small damper head to the center of the wire clamp. As the weights of the two damper heads are different, and the distances of the two damper heads relative to the body of the wire clamp are different, the novel damper can form a plurality of different resonance frequencies, effectively control vibration formed by a breeze, and prevent metal fatigue, thereby prolonging the service life of a lead.
