TECHNICAL FIELD
[0001] The utility model relates to the cutting tool related technical field, concretely is a pipe cutter. BACKGROUND
[0002] The market lacks special plastic pipe safety clamps, and operating personnel often use vise grips and needle-nose pliers to clamp, which has low reliability. In addition, in the process of installing and heating plastic pipes, direct hand holding inevitably causes bumps and scalds, and has low safety. The existing pipe cutter products on the market have single functions. In the process of plastic pipe splicing operation, the pipe cutter needs to be used with a clamp, and tools are frequently replaced, making the operation more complicated. To solve the above problems, a pipe cutter with stable switching of clamping and cutting functions is provided. UTILITY MODEL CONTENTS
[0003] In order to improve the ordinary pipe cutter, increase the operation function, simplify the use, a new type of pipe cutter design is provided.
[0004] The utility model discloses a pipe cutter with convenient and stable switching of clamping and cutting functions, aiming at improving safety and stability in the use process. The utility model meets the clamping and cutting two kinds of work demands simultaneously, and improves work efficiency.
[0005] The utility model provides the following technical scheme:
[0006] A pipe cutter, comprising a movable handle, a fixed handle and a cutting blade fixedly installed at the top end of the movable handle, wherein the top end of the fixed handle is integrally connected with an arc-shaped clamping jaw; and the end of the cutting blade is inserted into the inside of the movable handle from the top end of the movable handle and is fixedly connected with the movable handle.
[0007] The movable handle is integrally connected with an arc-shaped clamping jaw.
[0008] When the clamping function is used, the end of the movable handle is connected with the top end of the movable handle, the cutting blade is completely covered in the movable handle, and the cutting blade and the movable handle move together to clamp the target.
[0009] When the cutting function is used, the end of the movable handle is separated from the top end of the movable handle, the cutting blade rotates out of the inside of the movable handle, and the target is cut.
[0010] Further, the end of the movable handle is provided with a limiting groove, the top end of the movable handle is provided with a sliding groove, a push key is arranged in the sliding groove, and the push key is pushed to realize the connection or separation of the movable handle and the movable handle.
[0011] Further, the inner side of the movable clamp is provided with anti-skid teeth to increase the friction between the movable clamp and the pipeline, facilitating clamping; the outer end of the movable clamp is additionally provided with a circular cake structure with a radius of 5.2 mm, and a limiting pin is arranged on the circular cake structure; in the cutting state, after the cutting blade separates from the movable clamp and moves, when the cutting blade touches the limiting pin, the cutting blade and the movable clamp rotate together at an angle of 45 degrees until the cutting blade completes the cutting work. The arrangement of the limiting pin avoids arbitrary rotation of the movable clamp and hinders work.
[0012] Further, the inner side of the movable clamp is provided with a notch below the anti-skid teeth to facilitate the rotation of the cutting blade. The inner side of the movable clamp is provided with a notch corresponding to the rotation path of the cutting blade, so as to facilitate the rotation of the cutting blade out of the covering of the movable clamp and cutting.
[0013] Further, the end of the cutting blade is fixedly connected with the top end of the movable handle through a plurality of rivets B. The end of the cutting blade is inserted into the movable handle from the top end of the movable handle and fixedly connected with the movable handle through the rivets B.
[0014] Further, the movable clamp, the cutting blade and the fixed handle are rotationally connected through rivets A. The movable handle can drive the movable clamp and the cutting blade to rotate around the rivets A.
[0015] Further, the limiting groove is arranged at a distance of 6 mm from the inner side of the end of the movable clamp, and the length, width and depth of the limiting groove are 8.5 mm, 6.2 mm and 1.5 mm respectively; the sliding groove is arranged at a distance of 6 mm from the inner side of the top of the movable handle, and the length, width and depth of the sliding groove are 17.5 mm, 6.2 mm and 1.5 mm respectively. When the clamping function is used, the push key is located in the limiting groove and the sliding groove, and the movable clamp is connected with the movable handle; when the cutting function is used, the push key is located in the sliding groove, and the movable clamp is separated from the movable handle.
[0016] Further, the end of the fixed handle is provided with a lock catch. In the non-working state of the tool, the handles are closed, the lock catch locks the movable handle, the fixed handle and the movable handle remain in the closed state, the tool remains in the closed state, and the safety and reliability are improved.
[0017] Further, the fixed handle is a double-layer structure, and when the clamping or cutting function is used, the inner side of the movable clamp or the cutting blade can enter the arc-shaped clamping jaw, facilitating clamping of pipelines with different diameters or complete cutting of the pipeline. The pipeline cutter has the following structures from the outside to the inside: the upper fixed handle (i.e. the upper arc-shaped clamping jaw), the upper movable clamp, the cutting blade, the lower movable clamp and the lower fixed handle (i.e. the lower arc-shaped clamping jaw).
[0018] The utility model discloses reasonable in design, safe and reliable, convenient to use. Through the pipe cutter of clamping, cutting switch stable, the application clever combination movable clamp and cutting blade structure, and the clamping and cutting function are combined. The movable clamp end and movable handle can be separated or connected conveniently. Thus the utility model has two motion states of separate motion or common motion.
[0019] When the tool is in non-working state, the fixed handle and the movable handle are closed and fixed, the lock catch on the fixed handle locks the movable handle, the fixed handle and the movable handle keep closed state, the tool keeps stable closed state, and the safety and reliability are improved. When the movable clamp and the cutting blade move together and clamp the target, the anti-skid teeth on the inner side edge of the movable clamp contact the target, the friction between the target and the movable clamp is increased, the target is not easy to separate from the arc-shaped clamp jaw and the movable clamp, and when the target is clamped, it is more stable and reliable. When the movable clamp is separated from the movable handle and cuts the target, the cutting blade can enter the double-layer structure of the arc-shaped clamp jaw, and complete cutting of the target is realized.
