Technical Field

[0001] This utility model relates to the field of pliers tools, and in particular to an interface pliers. Background Technology

[0002] Currently available pliers are mainly used for clamping, bending, cutting, fixing or twisting objects. Depending on their different uses and functions, pliers come in various types. Among them, most pliers have a fixed working end. Pliers with this fixed structure have certain limitations in actual use. They cannot perform angled clamping, so various styles of pliers are needed to meet the work requirements, which is extremely inconvenient. Utility Model Content

[0003] This utility model proposes an interface clamp to solve the problems mentioned in the background art, which are that the working end of the existing clamps has a fixed structure design, resulting in a narrow range of applications, great limitations, and extreme inconvenience.

[0004] The technical solution of this utility model is implemented as follows:

[0005] An interface clamp, comprising:

[0006] The first clamping arm has a first clamping head at one end;

[0007] The second clamping arm is intersected with and rotatably connected to the first clamping arm. At one end of the second clamping arm, a second clamping head is provided to cooperate with the first clamping head to clamp the item. The second clamping head is rotatably installed at the end of the second clamping arm.

[0008] Preferably, an elastic element is provided at the connection between the first clamping arm and the second clamping arm. The elastic element is configured to drive the first clamp and the second clamp to separate from each other when the interface clamp is not subjected to external force.

[0009] Preferably, the elastic element has a spiral structure with outwardly extending limiting ends at both ends. An annular groove is provided at the connection between the first clamping arm and the second clamping arm. The elastic element is placed in the annular groove, and a slot is provided on the side wall of the annular groove of both the first clamping arm and the second clamping arm. The limiting end of the elastic element is engaged in the slot.

[0010] Preferably, the outer surface of the first clamping arm is provided with a rotatable locking block, and the outer surface of the second clamping arm is provided with a limiting step. The locking block can abut against the limiting step, thereby preventing the first clamping arm and the second clamping arm from opening.

[0011] Preferably, the first clamping arm includes a first handle and a first clamping handle, and the second clamping arm includes a second handle and a second clamping handle;

[0012] The center line between the first handle and the second handle coincides with the center line between the first clamp and the second clamp.

[0013] Alternatively, the center line between the first handle and the second handle forms an angle with the center line between the first clamp and the second clamp.

[0014] Preferably, both the first handle and the second handle are fitted with insulating sleeves.

[0015] Preferably, both the first handle and the second handle have clearance grooves on their facing surfaces.

[0016] Preferably, both the outer surfaces of the first chuck and the second chuck are provided with anti-slip parts.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0037] like Figure 1-6 As shown, an interface clamp includes:

[0038] The first clamping arm 1 has a first clamping head 103 at one end. The first clamping arm 1 includes a first handle 101 and a first clamping handle 102, wherein the first clamping head 103 is located at the end of the first clamping handle 102.

[0039] The second clamping arm 5 intersects with and is rotatably connected to the first clamping arm 1. At one end of the second clamping arm 5 is a second clamping head 6 that cooperates with the first clamping head 103 to clamp the item. The second clamping head 6 is rotatably mounted at the end of the second clamping arm 5. Specifically, the second clamping head 6 is rotatably mounted at the end of the second clamping arm 5 via a pin. Its axis of rotation is parallel to the rotation center of the first clamping arm 1 and the second clamping arm 5. In practice, there is a certain friction between the second clamping head 6 and the rotating shaft, preventing the second clamping head 6 from easily rotating around its rotation center. The second clamping arm 5 includes a second handle 501 and a second clamping handle 502. The second clamping head 6 is located at the end of the second clamping handle 502. Specifically, the rotation axis of the first clamping arm 1 and the second clamping arm 5 is located between the first handle 101 and the first clamping handle 102, and similarly, also between the second handle 501 and the second clamping handle 502.

[0040] More specifically, the first clamping arm 1 has an outwardly protruding central shaft 104 at its middle position, and the second clamping arm 5 has a central hole 504 at its middle position. The central shaft 104 is placed inside the central hole 504, so that the two can be rotatably coupled.

[0041] Specifically, both the first clamp 102 and the second clamp 502 have shearing portions on their opposing sides. The edges of these shearing portions have stripping grooves. More specifically, the first clamp 102 has a first shearing portion 1021 on its side, and the edge of the first shearing portion 1021 has a first stripping groove 1022. The first stripping groove 1022 is semi-circular, and in this example, there are three of them. The three first stripping grooves 1022 have different sizes, used for stripping wires of different diameters. Similarly, the second clamp 502 has a second shearing portion 5021 on its side, which... The first cutting part 1021 and the second cutting part 5021 can cut the wire. The edge of the second cutting part 5021 is provided with a second stripping groove 5022. The second stripping groove 5022 is semi-circular and there are three of them. The three second stripping grooves 5022 are different in size. Each second stripping groove 5022 corresponds to the size of each of the first stripping grooves 1022. After the rubber outer sheath of the wire is cut, the wire is placed in the circular space formed by the first stripping groove 1022 and the second stripping groove 5022 to achieve the effect of stripping the wire.

[0042] Specifically, an elastic element 4 is provided at the connection between the first clamping arm 1 and the second clamping arm 5. The elastic element 4 is configured to drive the first clamp 103 and the second clamp 6 to separate from each other when the interface clamp is not subjected to external force.

[0043] In this example, the elastic element 4 has a spiral structure. More specifically, the spiral elastic element 4 is formed by arranging slender springs in a spiral, with outwardly extending limiting ends 401 at both ends. An annular groove is provided at the connection between the first clamping arm 1 and the second clamping arm 5, and the elastic element 4 is placed in the annular groove. A retaining groove is provided on the sidewall of the annular groove of both the first clamping arm 1 and the second clamping arm 5, and the limiting end 401 of the elastic element 4 is engaged in the retaining groove. Specifically, the middle of the first clamping arm 1 has a central axis 10. The first annular groove 106 is coaxial with the second annular groove 504. The side wall of the first annular groove 106 is provided with a first slot 105. The middle part of the second clamping arm 5 is provided with a second annular groove 503 that is coaxial with the center hole 504 and has the same size as the first annular groove 106. The second slot 506 is provided at this position of the second annular groove 503. The elastic element 4 is first placed in the annular space formed by the first annular groove 106 and the second annular groove 503. Then, the two limiting ends 401 are respectively inserted into the first slot 105 and the second slot 506 to realize the assembly of the elastic element 4.

[0044] The working principle of the elastic element 4 is as follows: when the first clamping arm 1 and the second clamping arm 5 are in a clamping state, the first clamping arm 1 and the second clamping arm 5 can overcome the elastic force of the elastic element 4 to achieve the clamping effect on the object; when the force acting on the first clamping arm 1 and the second clamping arm 5 disappears, under the action of the elastic force of the elastic element 4, the first clamping arm 1 and the second clamping arm 5 can rotate relative to each other, thereby separating the first clamp 103 from the second clamp 6.

[0045] Specifically, the outer surface of the first clamping arm 1 is provided with a rotatable locking block 2, and the outer surface of the second clamping arm 5 is provided with a limiting step 505. The locking block 2 can abut against the limiting step 505, thereby preventing the first clamping arm 1 and the second clamping arm 5 from opening. This arrangement is used to lock the object at the limiting step 505 after clamping it, preventing the first clamp 103 and the second clamp 6 from separating. At this time, the hand holding the interface clamp can be released, thus freeing the hand.

[0046] In this example, as Figure 2 As shown, the center line (OA) between the first handle 101 and the second handle 501 coincides with the center line (OB) between the first clamp 102 and the second clamp 502.

[0047] Specifically, both the first handle 101 and the second handle 501 are equipped with insulating sleeves 3 to increase friction and provide electrical insulation.

[0048] Specifically, both the first handle 101 and the second handle 501 have relief grooves 7 on their facing surfaces. In this example, there are two relief grooves 7 on each of the two handles to prevent fingers from being pinched.

[0049] Specifically, both the outer surfaces of the first chuck 103 and the second chuck 6 are provided with anti-slip portions 601. More specifically, in this example, the anti-slip portion 601 is a spiked structure. Example

[0050] like Figure 7-8 As shown, the difference between this embodiment and the above embodiment is only that the center line (OM) between the first handle 101 and the second handle 501 and the center line (ON) between the first clamp 102 and the second clamp 502 form an angle with each other. In this example, the angle is an obtuse angle α. More specifically, the angle of the obtuse angle α is 145°. This is mainly used to meet the needs of use in confined spaces or different working environments, so as to improve the flexibility of operation.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
