固定するものであつた。(Prior Art) Traditionally, cutter holders have used two members with a semicircular cross section, one of which has a groove formed in its end surface into which the cutter can be inserted. There are some that are attached through subsequent processing and configured to have a perfect circular cross section. After inserting the cutter blade into this groove, screw the set screw into the screw hole provided on the side of one of the members, press the cutter blade with the tip of this set screw, and then press the cutter blade with the set screw. and the other member.
（考案が解決しようとする問題点）
しかし従来構成のカツターホルダーは、上記し

た。(Problem that the invention aims to solve) However, as mentioned above, the cutter holder of the conventional structure requires secondary processing such as brazing, and the cutter blade of the set screw is used to clamp and fix the cutter blade. Since the pressing force acts on the adhesive surface of the semicircular member in the direction of peeling off the adhesive surface, there is a high possibility that the cutter holder will be destroyed.
そこで本考案の目的は、加工が容易であり、安
全かつ確実にカツター刃を保持することのできる
カツターホルダーを提供することにある。 Therefore, an object of the present invention is to provide a cutter holder that is easy to process and can hold a cutter blade safely and reliably.

ものである。(Means for Solving the Problems) In order to achieve the above object, the present invention features a shaft body, a cap that fits into the shaft body, and a set screw that is screwed into the shaft body to fix the cutter blade. The shaft body is formed with a groove into which the cutter blade can be inserted and a screw hole that reaches the groove, and the front wall of the cap has a groove in which the cutter blade can be inserted. The cap has an opening through which the cutter blade can be inserted, and a hole is formed in the side wall of the cap to face the screw hole, and a set screw is screwed into the screw hole of the shaft to fix the cutter blade. At the same time, the cap is designed to prevent the cap from detaching.

る。(Function) Therefore, after fitting the cap to the shaft, insert the cutter blade into the groove of the shaft, screw the set screw into the screw hole of the shaft, and tighten. As a result, the shaft body is pushed in the direction of expansion by the set screw, but its expansion is regulated by the inner surface of the cap, and the cutter blade is inserted into the split groove opposite the set screw through the set screw and the cutter blade. It is firmly fixed in the groove by being pressed and clamped by the surfaces. If the cutter blade breaks inside the split groove, you can easily remove the cutter blade fragments by removing the set screw and removing the cap.

しているものである。 As shown in the first figure, the tip of the shaft 1 is formed into two shaft portions 12 and 13 with a semicircular cross section by a groove 11 having a width that allows the cutter blade C to be inserted. 12 is formed with a screw hole 12a that reaches from its outer circumferential surface to this split groove. cap 2
can be fitted to both shaft parts 12 and 13 of the shaft body 1, and its front wall 21 has an opening 2 through which the cutter blade C can be inserted.
1a, and a hole 22a that can face the screw hole 12a of the shaft body 1 is formed in its side wall 22. The tip of the set screw hole 3 passes through the hole 22a of the cap 2 and is further screwed into the screw hole 12a of the shaft 12, as shown in FIGS.
The cutter blade is fixed by pressing the side surface of the cutter blade located inside. The head 3a of the set screw 3 is engaged with the hole 22a of the cap 2.

3 and align the hole 22a of this cap with the screw hole 12a of the shaft 1, then insert the cutter blade C through the opening 21a of the cap 2 and insert it into the slot 11 of the shaft 1. Insert into. Then set screw 3
is passed through the hole 22a of the cap 2, and its tip is screwed into the screw hole 12a of the shaft body and tightened. As this tightening is done, the shaft body 11 is expanded in the direction of expansion by the setscrew 3. Although it is pressed, its spread is restricted by the inner surface of the cap 2, and the cutter blade C is pressed and held between the set screw 3 and the shaft portion 13, and is securely fixed within the split groove 11. be. At the same time, since the head 3a of the set screw 3 is located within the hole 22a of the cap 2, the cap 2 is prevented from detaching from the shaft body 1 or spinning idly. If the cutter blade C breaks within the groove 11, the pieces of the cutter blade can be easily removed by removing the set screw 3 and removing the cap 2 from the shaft body 1. Furthermore, when replacing the cutter blade C with a wider one, it is only necessary to replace it with one that has a wider inner diameter of the opening 21a of the cap 2.
