Example one

A heavy pipe wrench comprises a wrench handle 1, a movable jaw 2, a fixed jaw 3, a movable nut 4 and a sleeve 8. The clamp handle 1 is in a long strip shape, and the fixed jaw 3 is fixedly connected to the head end of the clamp handle 1 through a rivet. The movable jaw 2 is approximately 7-shaped, the forceps handle 1 comprises a threaded portion 5 and a hook portion 6, and the forceps handle 1 is integrally formed. The thread part 5 is connected with the clamp handle 1 in a sliding mode, the clamp handle 1 is provided with a groove, and the movable nut 4 is connected into the groove in a rotating mode and is in threaded connection with the thread part 5. The hook head part 6 extends to be opposite to the fixed jaw 3, and convex edges used for increasing friction force are arranged on the surface of the hook head part 6 opposite to the fixed jaw 3. The tail end of the forceps handle 1 is provided with a first inner hole 7, and the first inner hole 7 is a regular hexagon hole. The outer contour of the sleeve 8 is also a regular hexagon, the sleeve 8 can be placed in the first inner hole 7, and the sleeve 8 is provided with a second regular hexagon inner hole 11. Since the first and second bores 7 and 11 are each regular hexagonal, torque can be transmitted. The sleeve 8 can be made in a range of different sizes to accommodate different models of bolts or removable nuts. The second inner hole 11 can be used for screwing or unscrewing locking parts, such as bolts, movable nuts and the like, so that the pipe wrench has the function of a wrench, and the functionality of the pipe wrench is improved. The movable nut 4 is cylindrical, three circles of knurls 12 are arranged at intervals on the movable nut 4, and the three circles of knurls 12 are distributed along the axial direction of the movable nut 4 at intervals. Such a design can facilitate the operator to turn the movable nut 4 and thus adjust the movable jaw 2. The threaded part of the threaded part 5 and the movable nut 4 at least comprises four screw threads, so that the meshing area of the threaded part 5 and the movable nut 4 is increased, and the threads are not easy to scratch.
