Abstract

PURPOSE: To securely connect a cutter body to a cutter holder, by a method wherein a key, which is formed such that an elastic substance, such as solid rubber, is nipped with 2 metal plates and is formed into a monolithical unity, is simply inserted into a key hole.
CONSTITUTION: After a cutter body 1 is inserted into a cutter holder 2, a lamellar key 13 is inserted from the side of the cutter holder 2, and is pressed all the way through into the other side of the holder 2 by means of a tool, such as hammers, enough to completely reveal a projecting part at the end of the key 13. With this the key 13 is bound, and simultaneously, the cutter body 1 is securely connected. The key 13 is constituted such that an elastic substance, such as solid rubber, is nipped with 2 metal plates 10 and 11, and they are formed into a monolithical unity in a manner that its width is formed so as to be slightly wider than the width of the key hole 16. In case the cutter body 11 is removed, it is simply removed by pushing it out in the opposite direction to the direction which is taken in the case of the installation by means of a hammer and the like.
