As preferably, cutter is provided with boss, keeper, blade from top to bottom successively; Keeper is rectangle keeper; Blade one end is provided with blade, and the angle between blade and keeper horizontal plane is 30 °-60 °, and the width of blade is 2.5mm.Blade width, determine the length of chamfering in three-way connector, the blade width of 2.5mm is best width, this blade width, the requirement of chamfering in not only having met fast, and when the second rotating shaft puts in three-way connector, blade can not produce because of the collision of the second rotating shaft and three-way connector inwall problem that can not chamfering; Angle between blade and keeper, has determined and the gradient of chamfering in three-way connector has conventionally used 30 °, 45 °, 60 ° these three angles.
As preferably, cutter is connected with the second rotating shaft by spring.Cutter is connected with the second rotating shaft by spring, has not only avoided cutter in the time not using, and avoids touching and causing blade to damage with extraneous sharp objects; Meanwhile, the second rotating shaft can enter after the less three-way connector to be processed in aperture smoothly, then cutter is stretched out and realizes processing parts.
As preferably, in the second rotating shaft, be also provided with the first groove, the second groove, the first groove is arranged on the top of the second groove; In the first groove, be provided with cover plate, controll block, in the second groove, be provided with cutter.Cutter is not in the time using, and a part can, in the first groove, by the interaction between controll block and cutter, realize moving down of cutter.
The utility model, owing to having adopted above technical scheme, has significant technique effect: by changing the angle between the first locating shaft and the first support bar, two sections that have solved threeway fixture do not need the not orientation problem on same straight line of chamfering pipeline; Meanwhile, by changing knife edge angular, realize the object of the different chamferings of processing.
