Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hardware tools, and particularly relates to a multifunctional manual tool pliers. Background Art
[0002] At present, the connection method of the known PEX pipe or aluminum-plastic composite pipe with the pipe joint usually adopts a metal clamp or a clamp clamp connection. The metal clamp uses a special pliers to clamp the end and lock it. This connection method ensures the sealing and stability of the pipeline to a certain extent, but there are also some problems. In particular, when the pipeline route is dismantled or the installation is wrong, it is difficult to remove it from the pipe fitting or pipe joint because the clamp or clamp has been clamped. That is, once it is found that the pipeline needs to be dismantled, the entire connection part cannot be reused because the clamp or clamp cannot be removed again. This means that even if the rest of the pipeline is intact, the entire connection part and the pipeline still have to be discarded together. Such waste is not only a waste of materials, but also increases the cost of repairing and replacing pipelines. In addition, since the clamp or clamp is difficult to remove from the pipe fitting or pipe joint, it often takes a lot of time and effort to dismantle the entire connection part. During the disassembly process, it is also possible to cause damage to the pipeline or the connection part, thereby increasing the cost of repair and replacement.
[0003] Although there are special plastic pipe cutting pliers on the market, due to their structural limitations, one tool can only cut one type of pipe clamp. In other words, one tool can only cut the clamp ring or the clamp, and two types of pipe clamps cannot share the same tool. This limitation brings a lot of trouble to operators and significantly affects work efficiency.
[0004] First, since one tool can only be used for one type of pipe clamp, operators need to determine in advance which type of shearing pliers to use in order to correctly cut the pipe clamp when working on site. This increases the workload of operators and the possibility of errors. Secondly, since one tool cannot be used to cut different types of pipe clamps, operators need to carry a variety of different shearing pliers. This not only increases the number and weight of tools, but also increases the difficulty of carrying and managing tools. Most importantly, this limitation significantly reduces work efficiency. When working on site, if different types of pipe clamps need to be cut, operators have to change different shearing pliers, which not only wastes time but also affects the continuity and efficiency of work.
[0005] Another kind of tool pliers for locking metal clamps also only has a single-function pliers head for locking the end of the metal clamp. When it is necessary to disassemble the same kind of locking metal clamps, another special disassembly tool needs to be selected, which also has the above-mentioned problems.
[0006] Therefore, in order to improve work efficiency and convenience of operation, it is necessary to design a pliers tool with a metal clamp cutting function. Utility Model Content

[0030] For example, see Figure 1-Figure 3 A multifunctional hand tool pliers, as known to those skilled in the art, tool pliers are common hand tools, including a pliers head 1 and a pliers handle 2. The pliers head is located at the front end of the tool pliers, and is usually composed of two symmetrical clamping parts, which are used to clamp, clamp or cut materials. The shape and function of the pliers head are diverse, and common types include flat-nosed pliers heads, round-nosed pliers heads and diagonal pliers heads. Flat-nosed pliers heads are suitable for clamping objects of various shapes, round-nosed pliers heads are used to clamp, bend or rotate small parts, and diagonal pliers heads are used to cut metal wires or wires. The pliers handle is located at the rear end of the pliers head and is used to operate and control the tool pliers. The pliers handle is usually made of metal or plastic, providing a comfortable grip and good operating performance. The structural features of tool pliers make it one of the indispensable hand tools in various workplaces.
[0031] A shearing head is provided on the side of the pliers head. The shearing head has two cutting edges 3 that are combined with the side of the end of the metal clamp. A cutting slit 4 is formed between the two cutting edges for inserting the end of the metal clamp. The end of the metal clamp can be inserted into the cutting slit along the axial direction of the pipe. The strip opening of the cutting slit faces the side of the pliers handle. This design ensures that when the end is inserted into the cutting slit, the pliers handle and the pipe body form a shear torsion handle.
[0032] In this embodiment, the pliers head is a clamp locking pliers head for clamping the end of a metal clamp. Specifically, the pliers head and the pliers handle constitute a known pliers-shaped tool, that is, a clamping pliers for locking a metal clamp. The pliers head includes two pins 5 symmetrically arranged on the left and right and a positioning shaft 6 located in the middle of the pliers head. The front part of the pliers head forms two clamping parts 7 for clamping the two sides of the end of the metal clamp.
[0033] Furthermore, two end plates 8 are installed on both sides of the pliers head by pins, and an extension located on the side of the pliers head is formed on the same side of the two end plates, and the inner side of the outer end of the extension forms the cutting edge. A groove 8-1 is provided on the inner end surface of the extension, and the grooves of the two extensions constitute a slot located inside the cutting edge. A limiting boss 8-2 is formed at the lower part of at least one of the grooves, and the limiting boss forms a limiting structure located at the lower part of the slot, which can limit the insertion depth of the end of the metal clamp inserted from the upper end of the slot into the slot.
[0034] The method of using the clip head of this tool pliers is as follows:
[0035] See also Figure 4 The axial sides of the end 9-1 of the metal clamp 9 are provided with axial grooves 9-2 formed by clamping, and the outer side of the axial groove forms an axial end. Figure 5 , is a schematic diagram of installing a metal clamp using the clamp head of the manual pliers. The removal process of the metal clamp is as follows: Figure 6 The end is inserted into the slot from the front end of the clamping shear head along the axis of the tube body 10, and the blade slot is inserted into the axial groove of the end. After the end is inserted into the slot, the clamp handle and the tube body are used as shear handles to apply torsional shear force with both hands. Under the action of torsional shear force, the blade cuts off the end, and the end of the metal clamp is easily cut off.
