Description

Technical fields:

[0001] This utility model relates to the field of manual hardware tools, and in particular to a water pump pliers with a shearing mechanism on the handle. Background technology:

[0002] Traditional water pump pliers, as illustrated in patent application CN218747156U (titled "Anti-Pinch Water Pump Pliers"), mainly consist of a fixed clamp body and a sliding clamp body, which are slidably connected by rivets. The fixed clamp body has a long groove and several arc grooves, while the sliding clamp body has a boss that mates with the arc grooves. When rotating the sliding clamp body, the boss can be positioned within different arc grooves to adjust the opening. This type of water pump pliers has two limitations: firstly, it can only tighten pipe fittings, limiting its function; secondly, when cutting thin steel wires or cables, it requires separate wire cutters or cable cutters, making operation inconvenient, time-consuming, and labor-intensive; and thirdly, gaps easily exist between the fixed and sliding clamp bodies after assembly, even after installing blades between them, deviations are prone to occur during cutting, often resulting in incomplete cuts. Currently, there is no good solution to these problems.

[0003] In summary, how to achieve the shearing function on a water pump clamp has become a technical problem that urgently needs to be solved in the industry. Utility Model Content:

[0004] To overcome the shortcomings of the prior art, this utility model provides a water pump pliers with a shearing mechanism on the handle, which solves the problem that the previous water pump pliers could only screw on pipes and has a single function, and also solves the problem that deviations are easy to occur during shearing, resulting in failure to cut.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A water pump clamp with a cutting mechanism in the handle includes a fixed clamp body and a sliding clamp body, which are connected by a pivot pin. The handle of the fixed clamp body is provided with a first blade near the pivot pin, and L-shaped plates are connected to both sides of the first blade, forming a through groove between the L-shaped plates and the first blade. The handle of the sliding clamp body is provided with a second blade near the pivot pin, and protrusions that cooperate with the through grooves are provided on both sides of the second blade. The through grooves are used to guide the protrusions. The second blade and the first blade cooperate to cut steel wire or cable.

[0007] The handle of the fixing clamp body is provided with a groove, the first blade is inserted into the groove, the side wall of the groove is provided with two through holes, and the first blade is provided with a threaded hole corresponding to the position of the through hole. The screw passes through the through hole and is threadedly connected to the threaded hole to fix the first blade to the fixing clamp body.

[0008] The first blade is integrally formed with the L-shaped plate.

[0009] The handle of the sliding clamp body is provided with a groove, the second blade is inserted into the groove, the side wall of the groove is provided with two through holes, and the second blade is provided with a threaded hole corresponding to the position of the through hole. The screw passes through the through hole and is threadedly connected to the threaded hole to fix the second blade to the sliding clamp body.

[0010] Both the first and second blades have inclined shearing blades at their ends, with the angle of the shearing blades being 5-40 degrees.

[0011] The first and second blades are staggered to achieve staggered shearing.

[0012] The head of the fixed clamp body is provided with a long groove and several arc grooves, and the sliding clamp body is provided with a boss that cooperates with the arc grooves.

[0013] The present invention adopts the above solution and has the following beneficial effects:

[0014] By providing a first blade near the pivot pin on the handle of the fixed clamp body and a second blade near the pivot pin on the handle of the sliding clamp body, the two blades work together to cut steel wires or cables. This allows for both tightening pipe fittings and cutting steel wires or cables, achieving multiple functions with one tool, reducing the time operators spend changing tools, and improving work efficiency. Furthermore, by providing through grooves on both sides of the first blade and protrusions on both sides of the second blade that mate with the through grooves, the protrusions of the second blade first enter the through grooves of the first blade during cutting, acting as a guide and ensuring that there is no gap between the first and second blades during cutting. This facilitates the cutting of steel wires or cables, resulting in better cutting performance. Attached image description:

Detailed implementation method:

[0020] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, a water pump clamp with a shearing mechanism in the handle includes a fixed clamp body 1 and a sliding clamp body 2, which are connected by a pivot pin 3. The head of the fixed clamp body 1 is provided with a long groove 4 and several arc grooves 5. The sliding clamp body 2 is provided with a boss 6 that mates with the arc grooves 5. The handle of the fixed clamp body 1 is provided with a first blade 7 near the pivot pin 3. L-shaped plates 8 are connected to both sides of the first blade 7, and a through groove 9 is formed between the L-shaped plates 8 and the first blade 7. The handle of the sliding clamp body 2 is provided with a second blade 10 near the pivot pin 3. The two sides of the second blade 10 are provided with protrusions 11 that mate with the through groove 9. The two protrusions 11 can limit the movement of steel wire or cable during shearing. The through groove 9 is used to guide the protrusions 11 to ensure that there is no gap between the first blade 7 and the second blade 10 during shearing. The second blade 10 and the first blade 7 work together to shear steel wire or cable.

[0022] The handle of the fixing clamp 1 is provided with a groove, the first blade 7 is inserted into the groove, the side wall of the groove is provided with two through holes, and the first blade 7 is provided with a threaded hole 12 corresponding to the position of the through hole. The screw passes through the through hole and is threadedly connected to the threaded hole to fix the first blade 7 to the fixing clamp 1, which facilitates the disassembly and replacement of the first blade 7.

[0023] The first blade 7 is integrally formed with the L-shaped plate 8.

[0024] The handle of the sliding clamp body 2 is provided with a groove, and the second blade 10 is inserted into the groove. The side wall of the groove is provided with two through holes, and the second blade 10 is provided with a threaded hole 12 corresponding to the position of the through hole. The screw passes through the through hole and is threadedly connected to the threaded hole to fix the second blade 10 to the sliding clamp body 2, which facilitates the disassembly and replacement of the second blade 10.

[0025] The ends of the first blade 7 and the second blade 10 are both provided with inclined shearing blades 13. The angle of the shearing blades 13 is 5-40 degrees, which can ensure a certain strength and cut steel wires or cables.

[0026] The first blade 7 and the second blade 10 are staggered, and the shearing blades 13 of the first blade 7 and the second blade 10 are used to achieve staggered shearing, which is beneficial for cutting steel wires or cables.

[0027] Working principle:

[0028] During operation, when cutting steel wire or cable, there is no need to equip the machine with wire cutters or cable cutters. Simply slide the sliding clamp 2 along the long groove 4 of the fixed clamp 1 to the maximum opening, then place the steel wire or cable on the first blade 7, and then compress the fixed clamp 1 and the sliding clamp 2. The protrusion 11 of the second blade 10 will first enter the through groove 9 of the first blade 7, which will act as a guide to ensure that there is no gap between the first blade 7 and the second blade 10 when cutting. The cutting edges 13 of the first blade 7 and the second blade 10 will cut the steel wire or cable by cutting them alternately. This utility model of pump pliers can both screw pipe fittings and cut steel wire or cable, realizing multiple functions of one tool, reducing the time for operators to change tools, and improving work efficiency.
