Referring to the drawings, in order to prevent the fire hydrant (1) from being damaged, a protective frame (2) is installed around a certain distance of the fire hydrant (1) as shown in FIG.

Accordingly, if you want to use fire extinguishing water through the fire hydrant (1), you need to rotate the outdoor fire hydrant valve (3) in the direction of opening. In use, according to the size of the outdoor fire hydrant valve (3), the spanner (4) is rotated with the outdoor fire hydrant valve (3) accommodated in the first valve receiving groove (5) or the second valve receiving groove (6). The outdoor fire hydrant valve 3 is opened or closed.

However, as shown in FIG. 1, when the protective frame 2 or the safety frame is installed around the fire hydrant, when the spanner 4 is rotated, interference occurs with the protective frame 2 or the safety frame, so that the rotation is smooth. An unsupported problem occurs.

In order to solve this problem, some workers open and close using a pipe wrench, etc. When using such a pipe wrench, wear or damage occurs as the outdoor fire hydrant valve is formed of a copper material with relatively low hardness.

Therefore, there is a need to improve a spanner for opening and closing the valve of an outdoor fire hydrant that can smoothly open and close the valve of an outdoor fire hydrant without interfering with the protective frame or safety frame around the fire hydrant.
