Description

Technical Field

[0001] This utility model relates to the field of tool shearing technology, specifically to a multifunctional side shear. Background Technology

[0002] Pliers are multi-functional hand tools widely used for clamping, fixing, twisting, bending, and cutting metal wires. Pliers come in various forms, commonly including pointed, flat, round, and curved jaws, to accommodate different workpiece shapes. Based on their main function and usage, pliers can be categorized into clamping pliers, wire cutters, wire strippers, pipe cutters, and many other types. Current pliers technology is limited in function and cannot integrate the multiple functions of scissors and clamps. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a multifunctional side cutter to achieve the purpose of diversified functions and high practicality.

[0004] Specifically, this utility model provides a multifunctional side-cutting shear, including a first clamp body, a second clamp body, and a torsion spring assembly. The first clamp body includes a first clamp head and a first handle portion; the second clamp body includes a second clamp head and a second handle portion; the first clamp head and the second clamp head are rotatably connected by the torsion spring assembly; a first blade is provided on the side of the first clamp head, and a second blade is provided on the side of the second clamp head. In the natural state, the first clamp head and the second clamp head are in a separated state, and the first blade and the second blade are in a separated state. By gripping the first handle portion and the second handle portion, the first clamp head and the second clamp head are clamped together to achieve the clamping function. At this time, the first blade and the second blade are engaged to achieve the scissor function.

[0005] This utility model's multi-functional side cutter combines the functions of a side cutter and pliers. The first plier head and first handle are integrally formed, as are the second plier head and second handle. A torsion spring assembly is embedded between the first and second plier heads, utilizing the rotational elasticity of the torsion spring assembly to separate the first and second plier heads. A key inventive feature of this utility model is the inclusion of blades at the plier head position. The engagement of the first and second blades is synchronized with the movement of the first and second plier heads, and the side design of the first and second blades does not affect the pliers' functionality, facilitating cutting of fishing line or electrical wires.

[0006] Furthermore, the first pliers head has a first protrusion on its side, and the first pliers head and the first protrusion are integrally formed; the second pliers head has a second protrusion on its side, and the second pliers head and the second protrusion are integrally formed; the first protrusion and the second protrusion are respectively provided with recessed positions, and the first blade is fixed to the recessed position of the first protrusion by screws; the second blade is fixed to the recessed position of the second protrusion by screws.

[0007] The first and second protrusions are designed for mounting the first and second blades, and are secured with screws. This allows for the replacement of blades of different shapes or the replacement of new blades, enhancing practicality. To make the overall structure more compact, both the first and second blades are mounted in recessed positions, avoiding protrusions and ensuring that the overall height is close to that of the first and second jaw heads. The first and second blades have identical structures, with a threaded hole at one end through which a screw is passed to secure them in the recess. Both the first and second blades have a beveled surface from the connecting end to the cutting edge for easier cutting. Furthermore, a locking mechanism is included for securing the first and second handle portions.

[0008] When the torsion spring assembly is not under force, the first and second handle parts are in a spring-open state. At this time, the first and second blades, the first and second pliers heads are all separated, which is inconvenient to carry and poses a safety hazard. Therefore, this utility model also designs a locking device to fix the first and second handles. In the locked state, the first and second blades, the first and second pliers heads are clamped and engaged, which is convenient to carry and store and makes handling safer.

[0009] Furthermore, one end of the locking component is provided with a threaded hole, which is rotatably connected to the first handle part by a screw, the second handle part is provided with a locking pin, and the inner side of the locking component is provided with an n-shaped notch that engages with the locking pin.

[0010] To facilitate locking and unlocking, the locking component of this utility model adopts a rotary locking structure. When not in use, rotating the locking component allows the n-shaped notch to fit onto the locking post, locking the first and second handle parts, making it convenient for storage and carrying. When needed, sliding the locking component downwards disengages the n-shaped notch from the locking post, separating the two parts, making operation convenient and quick.

[0011] Furthermore, the outer side of the first clamp head is provided with multiple linear grooves.

[0012] The design of the linear groove facilitates wire cutting. Wires that are easy to cut can be cut using the linear groove, while wires that are difficult to cut can be cut using the side cutters, improving the tool's usability. Furthermore, the linear groove can be located on the side of either the first or second clamp head, both of which are within the protection scope of this utility model.

[0013] Furthermore, the second clamp head is provided with a first hanging through hole.

[0014] The design of the first hanging through hole makes it easy to hang the entire side cutter by hooking or threading a rope. In addition, the design of the first hanging through hole can also reduce the overall weight of the side cutter to a certain extent.

[0015] Furthermore, the mating surfaces of the first and second jaw heads are sequentially provided with a first toothed portion, a first circular hole portion, and a first notch portion from top to tail; the mating surface of the second jaw head includes a second toothed portion, a second circular hole portion, and a first clamping portion; when the first and second jaw heads are clamped, the first toothed portion engages with the second toothed portion; the first and second circular holes portion form a circular clamping position; the first clamping portion is embedded into the first notch portion to achieve engagement. Preferably, the number of circular clamping positions is 2 to 3, and the diameter of each circular clamping position is different.

[0016] To achieve multifunctionality of the first and second clamping heads, the clamping heads of this invention have various configurations. The circular clamping positions have different aperture diameters, suitable for stripping wires of different diameters. More preferably, there are two circular clamping positions, with the diameter increasing from the top to the tail. A non-circular clamping position can also be designed at the tail where the first and second teeth engage. The size of this non-circular clamping position can be smaller than the size of the circular clamping position, facilitating the matching of wires of different diameters. The first notch is semi-circular, and the first clamping part is also semi-circular. When the first and second clamping heads are clamped, the first clamping part engages with the first notch, allowing for cutting of ropes or wires.

[0017] Furthermore, the first handle portion has a first cover plate and a first hand grip plate arranged sequentially on its upper and lower sides; the second handle portion has a second cover plate and a second hand grip plate arranged sequentially on its upper and lower sides; the tail portions of the first handle portion and the second handle portion are respectively provided with a first hanging hole and a second hanging hole.

[0018] Since the first and second hand grips of the first handle can be made of plastic or silicone, and the surface can be designed with anti-slip texture, the first and second hanging holes are easy to be integrally formed with the first and second handles, and can be directly hung on a hook, or can be hung with a hanging rope.

[0019] Furthermore, the torsion spring assembly includes a central female nut, a bearing ring, a torsion spring element, a washer, and a central male nut; the central female nut passes through the bearing ring, the first clamp head, and the torsion spring; the central male nut passes through the washer and the second clamp head in sequence and connects to the central female nut, thereby realizing the rotational connection between the first clamp head and the second clamp head.

[0020] Both the first and second jaw heads have mounting positions for installing the torsion spring on their connecting surfaces. The relative rotation of the first and second jaw heads compresses the torsion spring, and the spring's rebound force causes the first and second jaw heads to separate.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) This utility model achieves the dual functions of pliers and side cutters by setting a first blade and a second blade on the side of the first and second pliers heads, which is highly practical. At the same time, the detachable installation method of the first and second blades of this utility model makes it convenient to replace and update, thereby improving the overall service life.

[0023] (2) The pliers of this utility model have various configurations. The circular clamping position has different hole diameters, which are suitable for stripping wires of different diameters. It is also designed with irregular clamping positions to facilitate matching wires of different diameters or shapes. At the same time, through the interlocking design of the first notch and the first clamping part, it can be used to cut ropes or wires.

[0024] (3) This utility model also includes a locking mechanism that can movably lock the first handle and the second handle, improving the portability and safety of the entire side scissors. Hanging holes are also designed at the ends of the first and second handles, or on either the first or second handle, to facilitate hanging and storage at both ends. Attached Figure Description
