[0002] Pliers are a kind of hand tool used to clamp, fix workpieces or twist, bend and cut metal wires. The pliers are V-shaped and usually consist of three parts: handle, pliers head and cutting edge. Pliers are generally made of carbon structural steel. They are first forged and rolled into the shape of pliers blanks, then undergo metal cutting processes such as grinding, milling and polishing, and finally heat treated.

[0003] However, the existing pliers have only a fixed pair of cutting edges. When the pair of cutting edges is damaged, the entire pliers must be replaced. After the cutting edges are damaged, the pliers are scrapped and cannot be used, which causes waste.

[0004] For this reason, a kind of pliers with replaceable cutting edges is provided. Utility Model Content

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, the utility model has replaceable blade pliers, including a main pliers body 1 and an auxiliary pliers body 2, and also includes a blade component 11. The main pliers body 1 includes a main pliers head 3 and a main pliers handle 4, the auxiliary pliers body 2 includes an auxiliary pliers head 5 and an auxiliary pliers handle 6. The main pliers head 3 is provided with a fixing groove 9 on the inner side, and the auxiliary pliers head 5 is provided with a fixing groove 2 10 connected with the fixing groove 9 on the inner side.

[0031] In this embodiment, specifically: the loss of the product can be reduced, only the cutting edge component 11 is replaced without replacing the pliers body, the cost of use can be greatly reduced, and the high cost performance of the product can be achieved. The main pliers body 1 and the auxiliary pliers body 2 are set as a separate design with the cutting edge component 11, and the cutting edge component 11 can be disassembled at any time.

[0032] In one embodiment, a matching cutting edge component 11 is provided on the inner side of the fixing groove 1 9 and the fixing groove 2 10, and the cutting edge component 11 includes a cutting edge 1 7 and a cutting edge 2 8. The angle at which the top surface of the cutting edge 1 7 and the top surface of the cutting edge 2 8 intersect is set to a bevel angle greater than 30 degrees, and the cutting edge 1 7 and the cutting edge 2 8 are staggered and connected to each other.

[0033] In this embodiment, specifically: the cutting edge with different angles and different cutting edge widths is replaced according to demand, and the cutting edge is selected according to actual conditions to achieve the indiscriminate use of the product in different scenarios.

[0034] In one embodiment, the main pliers head 3 and the main pliers handle 4 are integrally formed, the auxiliary pliers head 5 and the auxiliary pliers handle 6 are integrally formed, the main pliers body 1 and the auxiliary pliers body 2 are rotatably connected, the outer walls of the main pliers handle 4 and the auxiliary pliers handle 6 are provided with anti-slip patterns, and the outer walls of the anti-slip patterns are provided with anti-slip rubber.

[0035] In this embodiment, specifically: the stability of the main pliers handle 4 and the auxiliary pliers handle 6 during use is improved.

[0036] In one embodiment, a mounting hole 13 is provided on the outer wall of the cutting edge 1 7, a mounting hole 2 14 is provided on the outer wall of the cutting edge 2 8, and two groups of mounting holes 13 and 14 are respectively provided. An auxiliary hole 15 is provided on the inner side of the fixing groove 1 9, and an auxiliary hole 2 16 is provided on the inner side of the fixing groove 2 10. Two groups of auxiliary holes 15 and two groups of auxiliary holes 16 are respectively provided. The two groups of mounting holes 13 and auxiliary holes 15 are connected, and the two groups of mounting holes 2 14 and auxiliary holes 2 16 are connected. Matching mounting threaded rods 12 are provided between the two groups of mounting holes 13 and auxiliary holes 15, and matching mounting threaded rods 12 are also provided between the two groups of mounting holes 2 14 and auxiliary holes 2 16. The cutting edge component 11 is fixedly installed inside the fixing groove 1 9 and the fixing groove 2 10 through four groups of mounting threaded rods 12.

[0037] In this embodiment, specifically: four groups of mounting threaded rods 12 fix the cutting edge component 11 inside the fixing groove 1 9 and the fixing groove 2 10, so that different cutting edges can be replaced according to personal needs, which is convenient and quick. The signals of the four groups of mounting threaded rods 12 used in this solution are all M2.5*3.55*8, where M represents the thread diameter.

[0038] Working principle: When the cutting edge component 11 is damaged, rotate the four sets of mounting threaded rods 12 to remove the cutting edge component 11 from the inside of the fixing groove 1 9 and the fixing groove 2 10. At this time, the cutting edge component 11 needs to be removed and replaced with a new cutting edge 1 and cutting edge 2. The angle fit between the cutting edge 1 and the cutting edge 2 is greater than 30 degrees.

[0039] This makes it easy to replace the cutting edge with different angles and widths as needed, and select the cutting edge based on actual conditions, so that the product can be used in all scenarios without distinction.

[0040] After the replacement is completed, the four sets of threaded rods 12 are used to fix the cutting edge component 11 inside the fixing groove 1 9 and the fixing groove 2 10 , so as to facilitate the subsequent use.

[0041] The above is the overall working process of the utility model, and you can repeat this step next time you use it.
