Abstract: Cutting pliers include a first plier body and a second plier body. The first plier body includes a support end and a first handle coupled to each other. The second plier body includes a cutting end and a second handle coupled to each other. The first handle and the second handle are rotationally coupled by a connecting shaft. The support end and the cutting end cooperatively form jaws for cutting a pipe. The support end comprises a convex arcuate surface for supporting a pipe. The cutting end comprises two clamping arms and a blade. The blade is arranged between the two clamping arms. When the jaws are closed, a clamping end of the clamping arms abuts against the pipe, the pipe on the arcuate support surface is squeezed and deformed along the arcuate support surface to form an arcuate pipe, and the blade abuts against the arcuate pipe.

Abstract: A broken pipe extractor for removing a broken pipe from a pipe joint includes a hollow pipe body, a first blocking block, a second blocking block, and a hook needle assembly. The first blocking block is located in the pipe body for fixing one end of the pipe joint. The first blocking block defines a through hole. A diameter of the through hole is greater than or equal to an inner diameter of the pipe joint. The second blocking block is movably fixed to one end of the pipe body for fixing another end of the pipe joint. The hook needle assembly is configured to be inserted through the through hole of the first blocking block and extend to the broken pipe to remove the broken pipe.

Abstract: A broken pipe extraction device includes first, second, and third pressure plates, a fixing member, a fastening member, and a needle. The first pressure plate includes a first perforation and a second perforation connected to the first perforation. The second perforation passes through a side wall of the first pressure plate. The second pressure plate faces the first pressure plate. Projecting portions of the first perforation and the second perforation on the second pressure plate overlap. The third pressure plate includes a through hole. The third pressure plate is detachably received in the first perforation and the second perforation. The fixing member mounts on the second pressure plate and faces the first perforation and the second perforation. When the third pressure plate is received in the first and second perforations, the through hole faces the fixing member.

Abstract: A stripping device for rapid midpoint stripping of an outer cladding layer of a cable includes a handle, a cutter disposed on the handle, a pressing assembly, and a scraper assembly. The pressing assembly includes a first bracket and a pressing part. The first bracket is disposed on the handle. The pressing part is slidably arranged on the first bracket and opposite to the cutter. The scraper assembly includes a second bracket disposed on the handle and a scraper disposed on the second bracket. The stripping device has advantages of simple operation, high stripping efficiency, and good safety.

Abstract: A mechanical positioning structure includes a first positioning mechanism, a fixing post arranged through a central axis of the first positioning mechanism, a first driving mechanism, a second positioning mechanism rotationally arranged on the fixing post and coupled to the first driving mechanism, a second driving mechanism, and a platform. One end of the first driving mechanism is fixed on the fixing post. Another end of the first driving mechanism is slidably arranged on the first positioning mechanism. The second driving mechanism is arranged on the second positioning mechanism. The platform is arranged on the second driving mechanism. The first driving mechanism drives the second positioning mechanism to move on a surface of the first positioning mechanism and rotate the second positioning mechanism around the fixing post. The second driving mechanism drives the platform to move on the second positioning mechanism.
