Then, a through hole is formed in the center of the closing surface 18 of the sleeve 2, the shaft body 4 is inserted from the opening surface 19 side of the sleeve 2, and the tip end thereof is projected from the through hole of the closing surface 18. Then, each leg 5 is extended so that the shaft body 4 is located on the central axis of the sleeve 2, and the tip ends thereof are brought into contact with the inner surface of the sleeve 2. At the same time, the reference surface contact body 3 is brought into contact with the opening surface 19 of the sleeve 2. Next, the other end of the shaft body 4 is inserted into the hole at the end of the arm 6, and the length of the rear end of the arm 6 and the rear end of the shaft body 4 is fixed to Y. Next, the length L 1 of the marking portion 7 is set. This L 1 is L 1 = L 0 −Y−X obtained by subtracting the length of Y and the desired sleeve length X from the total length L 0 of the shaft body 4. Then, with the arm 6 fixed to the shaft body 4, the arm 6 is rotated to move the sleeve 2
Mark the cutting position on the l line on the outer circumference. Then, it is blown by an oxygen burner along the marking line. Then, the melted surface is finished, and both open ends of the sleeve 2 are groove-processed, and the cable penetration is performed in the sleeve 2 as shown in FIG.
It is sufficient to insert 14 and weld between the cylindrical body 17 of the cable penetration 14 and both ends of the sleeve 2.

Penetrate through. Since the marking portion 7 is provided at the other end via the arm 6, the dimension of the cutting position 1 of the sleeve 2 on the closed surface 18 side can be extremely easily determined.
That is, the required length X of the sleeve 2 in FIG. 1 is X = L 0 -L 1 -Y. Where L 0 is the total length of shaft 4
L 1 is the length of the marking portion 7, and Y is the length from the other end of the shaft body 4 to the arm 6. Therefore, fix the length of Y,
The cutting position 1 can be set only by setting the protrusion length L 1 of the marking portion 7 to L 0 −Y−X. The sleeve 2 can be accurately marked by rotating the marking section 7 around the axis of the shaft body 4.
