Post with integral hammer and anvil |
摘要 |
A post includes an elongate ground piercing member having a ground piercing end and an anvil end at which is positioned an anvil. The anvil is positioned within an interior cavity of a housing with the ground piercing member extending through a second end of the housing. Relative movement of the ground piercing member and the housing brings a first hammer into contact with the anvil to drive the ground piercing member into the ground. Relative movement of the ground piercing member and the housing brings a second hammer into contact with the anvil to remove the ground piercing member from the ground. A lock is provided to selectively limit relative movement of the ground piercing member and the housing to prevent the second hammer from contacting the second striking face of the anvil.
