发明名称 Post support apparatus with rotatable post guide
摘要 An apparatus for supporting a metal post while it is being driven into the ground utilizes a platen base and a guide member which is rotatably joined to the base for holding the post in a steady condition while the post is being driven into the ground. Because the guide member is rotatably joined to the base member, the rotational position of a post positioned within the guide member can be significantly altered with respect to the base.
