摘要： PURPOSE:To realize simple and sure tube connection by holding the groove part of a coupling by the crimping jaw of a tube connection tool, and at the same time, fitting a clamp to a groove in outer periphery of the end of the tube to confirm propriety of amount of insertion to the coupling. CONSTITUTION:A groove 43 having sectional form of circular arc is formed on the outer periphery of the cut end 7a of a tube 7 at a position longer than the length of insertion to a coupling 3 by a specified length, and inserted in the coupling 3 having an O ring fitted to the groove part 1. Then, the groove part 1 is held by the groove 14 of the crimping jaw of a tube connection tool, and at the same time, a linear projection 42 of a clamp 40 provided in a body with the crimping jaw 10 is fitted to the groove 43. After confirming that the amount of insertion of the tube 7 to the coupling is proper, jaws 10a, 10b are driven, and overlapped part of the coupling 3 and the tube 7 is clamped and pressure bonded. Thereby, improper connection of the coupling and tube can be prevented perfectly, and tube connection can be made simply and surely.

摘要： PROBLEM TO BE SOLVED: To provide a bar cutting device capable of cutting an end surface, so that the end surface can be made accurately vertical in an axis core direction without gripping a bar; and having high workability. SOLUTION: In a bar cutting device 10, in order to stabilize the attitude of the cutter 10 in a condition, where the rotation axis core of a disklike rotating cutting tool 16 is made parallel to the axis core direction of a bar 12a, which is provided with a pressing recessed surface 54, having the same shape in a cross section at right angle in the rotating axis core direction of the tool 16, and being possible to abut on the outer peripheral surface of the bar 12a. Between the pressing member 20 and a cutter 18, a tool guiding device; composed of a guiding member 42, guiding wall parts 144 and 146, and back plates 148 and 150; is provided which is for guiding the cutter 18 along a surface vertical in the rotating axis core direction of the tool 16, so that the tool 16, provided on the cutter 18, can near the bar 12a.
