摘要:
The shock-absorbing shovel handle comprises an upper handle, a lower handle, and a shock absorber. A tool element couples to the lower end of the lower handle. The upper handle comprises an upper cavity and the lower handle comprises a lower cavity. The shock absorber resides within the upper cavity and the lower cavity and is coupled to the upper handle at one end of the shock absorber and to the lower handle at the opposing end of the shock absorber. The lower handle extends into and slides within the upper cavity, with the sliding motion limited by the resistance of the shock absorber. If the tool element strikes an obstruction while being held by the upper handle, the shock of the strike is absorbed by the shock absorber as the lower handle slides into the upper handle and then returns to its starting position.
