  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention provides a rod fixing member comprising a rod-like binding member such as a nail and a rod-supporting member that supports the rod. Even if an external force is applied to the heel with the position fixed, it is an object to be able to fix the heel to the initial support position.

In order to solve the above-mentioned problems, the present invention provides a rod-like fastening member and an arm portion formed in a shape for holding the outer peripheral surface of the collar at one end of a base portion having a through hole through which a shaft portion of the rod-like fastening member is inserted. It consists of a heel support member that is freely connected, and the heel support member is fixed to the wall surface of the building with a rod-like fastening member, and the arm portion attached to the outer peripheral surface of the heel is locked to the other end of the base portion. In the scissor fixing tool that supports the scissors, a protrusion is provided on the peripheral surface of the shaft portion of the rod-like fastening member, and a concave groove through which the protrusion passes is provided in the through hole of the base of the scissors support member. A head portion of a rod-like fastening member having a shaft portion inserted through a hole and a protrusion penetrating the concave groove are configured to engage with the surface of the base portion.
The said structure WHEREIN: The recessed part in which the head of the rod-shaped fastening member which penetrated the axial part to the through-hole can immerse can be provided in a base part.

The attachment of the heel fixing tool of the present invention is performed by passing the shaft portion of the rod-like binding member through the through hole formed in the base portion of the heel support member, and driving the tip of the rod-like binding member into the wall surface of the building. While fixing to the wall surface and passing the protrusion provided on the circumferential surface of the rod-like binding member through the concave groove of the hole, the position of the base of the heel support member is moved to the head side of the rod-like fastening member, This can be done by rotating the scissors support member around the shaft portion of the rod-like fastening member at a position where the projection is exposed to the outside of the through hole, and engaging the projection with the surface on one side of the base. The head of the rod-like fastening member is engaged with the surface on the other side of the base.
