Pipe cutter

The present invention relates to a pipe cutter, in particular to a urgency that does not require repeated adjustment of the pipe member and the cutting blade, that is, the pipe member can be cut smoothly, making it easier and more convenient to operate and use. It is an innovative designer of the pipe cutter that uses the more practical and effective features.

According to the general construction of the pipe fittings during the construction process, the construction personnel will use the pipe cutter to cut the pipe fittings, and the pipe cutters mainly make the body a slightly C-shaped structure. The front end is provided with a plurality of wheel bodies in a rotatable manner, and a sleeve tube corresponding to the wheel body is disposed at a rear end of the body, and the body is provided with a pressable movable buckle near the sleeve tube. The device is provided with a hollow rod body and a slidable sleeve rod combined with the body sleeve tube, and the sleeve rod is provided with an internal thread on the inner surface and a plurality of recesses are arranged on the outer surface to be engaged with the buckle member. The positioning groove is combined with the sleeve rod and is provided with a blade actuating rod. One end of the actuating rod extends out of the sleeve in the direction of the wheel body, and the blade is rotatably disposed at one end of the operating rod extending from the sleeve. The other end of the actuating rod is combined with an operating head and simultaneously screwed with the internal thread of the sleeve, so that when the pipe cutter is used, the pipe to be cut is first placed on one end of the wheel body of the body. Pressing the snap fastener again, so that the snap fastener is disengaged from the positioning groove on the sleeve rod After the position, the push rod is moved toward the wheel body, so that the blade of the actuating rod abuts against the outer surface of the pipe to be cut. At this time, the body is rotated relative to the pipe, so that the blade rolls along the outer surface of the pipe and rotates at the same time. The head pushes the action rod to move in the direction of the wheel body, thereby achieving the purpose of cutting the pipe piece with the blade.

However, although the above-mentioned pipe cutter can achieve the expected effect of cutting the pipe fittings, it is also found in its actual application, that the structure has a certain thickness when the pipe is used, so that the actuating blade is abutted. When the outer surface of the pipe is rotated and cut, the blade of the actuating rod only cuts the outer surface of the pipe, and the pipe can not be cut and cut at one time. It needs to be adjusted again and again, so that the blade of the actuating rod is pressed against the outer surface of the pipe. The pipe can be cut smoothly, which makes it less convenient in operation and use, so that there is still room for improvement in the overall structural design.

The reason is that, in view of this, the creators have been researching and improving the existing structures and defects by providing rich experience in design and development and actual production of the relevant industries for many years, and to provide a pipe cutter for the purpose of achieving better practical value.
