Claims

[Scope of utility model registration request]

It is a replaceable blade type machine consisting of a handle 3 with a back metal 2 attached to the tip and a saw blade 4 attached to the tip of the handle 3, and configured so that the saw blade 4 can be arbitrarily replaced as needed. In the saw, the support shaft 6 formed in the gap 5 of the back metal 2 is engaged with the recess 7 formed in the saw blade 4 so that the saw can be locked. 5 is formed with either a protrusion 8 or a hole or a recess, while
The saw blade 4 is formed with any one of a hole 9, a recess, or a protrusion in a shape corresponding to the protrusion 8, hole, or recess, and when the saw blade 4 is attached to the back plate 2, A saw blade attachment structure for a replaceable blade saw, characterized in that a protrusion and a hole or a recess are formed so as to fit into each other.
