摘要

The spike (1) has a housing (2) with a cavity containing a stud (4) at a top surface (5) of the housing from the housing, so as to seize the stud on the top surface. The housing has an anchor (7) such as winter hand nail anchor, where the housing is partially manufactured from a biologically degradable plastic. The stud and the cavity are formed such that the stud is removed from the cavity by breaking the housing, where the diameter of the stud reduces over the length of the stud from the bottom of the cavity to the top portion.
