[0016] The present utility model provides a multifunctional folding fishing pliers.

[0017] In the embodiments of the present utility model, as Figures 1 to 7As shown in the figure, the multifunctional folding fishing pliers include a first plier body 1 and a second plier body 2. The first plier body 1 includes a first plier head 102 and a first plier handle 101 hinged to the rear of the first plier head 102. The second plier body 2 includes a second plier head 202 and a second plier handle 201 hinged to the rear of the second plier head 201. A limiting structure is provided at the hinge joints of the first plier handle 101 and the first plier head 102, and the second plier handle 201 and the second plier head 202. This limiting structure can be manually controlled to effectively position the first plier head 102 and the first plier handle 101, as well as the second plier head 202 and the second plier handle 201, in the unfolded and / or folded positions, thereby preventing or significantly reducing the relative displacement between the plier handle and the plier head under the action of non-artificial external forces (such as gravity or slight bumps and snags from other objects), thus facilitating the use and carrying of the fishing pliers. When it is necessary to switch the folding and unfolding positions of the plier head and the plier handle, the positioning of the plier head and the plier handle by the limiting structure can be manually released, and the operation is very convenient.

[0018] Specifically, a first hinge portion 103 is provided at the rear of the first plier head 102. The first plier handle 101 is hinged to the first hinge portion 103 and can swing relative to the first plier head 102 between the unfolded and folded positions. A second hinge portion 203 is provided at the rear of the second plier head 202. The second plier handle 201 is hinged to the second hinge portion 203 and can swing relative to the second plier head 202 between the unfolded and folded positions.

[0019] In the embodiment of the present invention, there are various embodiments of the limiting structure. For example, it can be a bolt (such as a wing bolt, not shown) screwed onto one of the plier handle and the plier head. When the plier handle is in the folded or unfolded position and needs to be positioned, the user can turn the wing bolt until the rod end thereof abuts against the other of the plier handle and the plier head. When it is necessary to switch positions, the bolt is loosened in the reverse direction, and the operation is relatively convenient.

[0020] As a preferred embodiment of the limiting structure, the limiting structure includes a receiving cavity 3 provided on one of the first plier head 102 and the first plier handle 101 and one of the second plier head 202 and the first plier handle 201, a positioning member 4 provided in the receiving cavity 3, and at least one positioning groove 5 provided at the hinge joint of the other of the first plier head 102 and the first plier handle 101 and the other of the second plier head 202 and the first plier handle 201. When the first plier head 102 and the first plier handle 101, and the second plier head 202 and the first plier handle 201 are in the folded or unfolded positions, the positioning member 4 is opposite to the positioning groove 5 and can be controllably partially inserted into or withdrawn from the positioning groove. When the positioning member 4 partially enters the positioning groove 5, the first plier head 102 and the first plier handle 101, and the second plier head 202 and the first plier handle 201 can be positioned. When it withdraws from the positioning groove 5, the positioning of the first plier head 102 and the first plier handle 101, and the second plier head 202 and the first plier handle 201 is released.

[0021] Specifically, when there is only one positioning groove 5 at the hinge joints of the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201, the positioning groove 5 can be set to the position opposite to the positioning member 4 when the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 are in the folded position, so that the positioning member 4 can partially extend or retract, thereby realizing the positioning of the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 in the folded position. Of course, the positioning groove 5 can also be set to the position opposite to the positioning member 4 when the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 are in the unfolded position, so that the positioning member 4 can partially extend or retract, thereby realizing the positioning of the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 in the unfolded position.

[0022] When there are two positioning grooves 5 at the hinge joints of the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201, the positioning grooves 5 can be respectively set to the positions opposite to the positioning member 4 when the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 are in the folded or unfolded positions, so that the positioning member 4 can partially extend or retract, thereby respectively realizing the positioning of the first jaw 102 and the first handle 101 and the second jaw 202 and the first handle 201 in the folded and unfolded positions.

[0023] In the above embodiments, the accommodating chamber 3 is preferably arranged in the first jaw 102 and the second jaw 202. Correspondingly, the positioning groove 5 is arranged in the first handle 101 and the second handle 201.

[0024] In some embodiments of the present invention, at least part of the positioning member 4 is an elastically telescopic structure, so that the positioning member can be controllably partially extended into or retracted from the positioning groove 5. Specifically, the positioning member 4 includes an elastically telescopic portion 41 arranged in the accommodating chamber 3 and elastically abutted against the bottom wall of the accommodating chamber 3 at one end, and a positioning portion 42 arranged at the other end of the elastically telescopic portion 41. The elastically telescopic portion 41 and the positioning portion 42 can be fixedly connected or only elastically abutted. When the positioning groove 5 is opposite to the positioning portion 42 and the elastically telescopic portion 41 expands and contracts, the positioning portion 42 can be made to partially extend into or retract from the positioning groove 5 to position or release the positioning of the handle and the jaw in the unfolded or folded position.

[0025] In some embodiments of the present utility model, the mating surface between the portion of the positioning part 42 extending into the positioning groove 5 and the positioning groove 5 is an arc surface or an inclined surface. In this way, when the user applies a force to the pliers handle and the pliers head to drive them to rotate relative to each other, the portion of the positioning part 42 extending into the positioning groove 5, under the guiding and pushing action of the arc surface, overcomes the elastic force of the elastic part 41 and moves towards the accommodating chamber 3, and finally exits the positioning groove 5, thereby releasing the positioning of the pliers handle and the pliers head. After the positioning part 42 exits the positioning groove 5 and is misaligned with the positioning groove, the flat surface outside the positioning groove presses against the positioning part 42, so that the positioning part 42 is located in the accommodating chamber 3. When the pliers head and the pliers handle are rotated relative to each other to the unfolded or folded position, the positioning part 42, under the elastic force of the elastic telescopic part 41, partially extends into the positioning groove 5 again to position the pliers handle and the pliers head at the unfolded or folded position. Of course, as an alternative embodiment, the portion of the positioning part 42 extending into the positioning groove 5 can also be in the shape of a pyramid or a frustum of a pyramid.

[0026] Specifically, the positioning part 42 has an overall columnar or spherical structure. When it is a columnar structure, the end extending into the positioning groove 5 is in the shape of an arc surface, a pyramid or a frustum of a pyramid.

[0027] In some embodiments of the present utility model, the elastic telescopic part 41 can be a spring, a columnar or tubular sponge body, a rubber ring or other structures.

[0028] It can be understood that in the preferred embodiment, the accommodating space 3 and the positioning member 4 are arranged on the hinge part, and the corresponding positioning groove 5 is arranged on the pliers handle. In some other embodiments, the positions of the two can be inverted, that is, the accommodating space 3 and the positioning member 4 are arranged on the pliers handle, and the positioning groove 5 is arranged on the hinge part.

[0029] Furthermore, in the shown preferred embodiment, the first pliers head 101 and the first pliers handle 201, as well as the second pliers head 201 and the second pliers handle 202 are all hinged by a hinge shaft. There are two positioning grooves 5 respectively arranged at the hinge joints of the first pliers head 101 and the first pliers handle 201 and at the hinge joints of the second pliers head 201 and the second pliers handle 202, and the two positioning grooves are correspondingly arranged on both sides of the hinge shaft to position the pliers head and the pliers handle when they are in the folded or unfolded position.

[0030] In the preferred embodiment, such as Figure 3 and Figure 7As shown, the positioning component 4 further includes a base body 43 disposed in the accommodating chamber 3. The base body 43 defines a guiding chamber 431 with one end open. The elastic telescopic portion 41 and the positioning portion 42 are disposed in the guiding chamber 431. The open end of the guiding chamber 431 has a contracting portion extending inwardly, and the open end forms a through port with a size smaller than the width or diameter of the positioning portion 42. One end of the elastic telescopic portion 41 abuts against the bottom of the base body 43, and the other end is connected to or abuts against the elastic telescopic portion 41. When the elastic contracting portion 41 extends, it can abut the edge of the positioning portion 42 against the contracting portion 44, and enable the portion of the positioning portion 42 for extending into the positioning groove 5 to pass through the through port. In this setting method, on the one hand, it can guide the elastic telescopic movement of the elastic telescopic portion 41 and the movement of the positioning portion 42, thereby improving the service life of the elastic telescopic portion 41 and ensuring the smooth entry and exit of the positioning portion 42 into and out of the positioning groove 5. On the other hand, it can improve the assembly efficiency between the positioning component 4 and the empty chamber 3.

[0031] In this embodiment, at least one of auxiliary tools such as a small knife 601, a file plate 602, a puncture cone 603, and a bottle opener 604 is hinged inside or outside the first pliers handle 101 and / or the second pliers handle 201. Among them, the small knife 601 functions for basic cutting 901 and separating items, etc., the file plate 602 functions for grinding items, the bottle opener 604 functions for opening bottle caps, and the puncture cone 603 has an obvious tendency in the field of use. The puncture cone 603 is generally used in fishing and can be used for deflating live fish and perforating the skull. The above-mentioned auxiliary tools are all prior arts, and their specific structures, usage methods, and installation methods will not be elaborated here.

[0032] Furthermore, as Figure 2 and Figure 3 shown, the above-mentioned auxiliary tools are provided with a concave or convex or hollowed-out grasping portion 605, so as to facilitate pulling the auxiliary tool from the grasping portion. Preferably, a layer of silica gel can be provided on the wall of the grasping portion 605 to improve the comfort and safety of use. In some other embodiments, the silica gel can also be replaced by soft materials such as rubber and sponge, and the soft materials of the prior art can be referred to.

[0033] Specifically, the first pliers handle 101 and / or the second pliers handle 202 define accommodating chambers 1010, 2010 with at least one side open. The auxiliary tools are hinged in the accommodating chambers 1010, 2010 and can swing into and out of the accommodating chambers 1010, 2010 around their hinge axes 7. When they swing out of the accommodating chambers 1010, 2010, the auxiliary tools can be used by the user.

[0034] Further, an outer limiting member 801 and an inner limiting member 802 are also provided inside the first jaw handle 101 and the second jaw handle 102. Among them, the outer limiting member 801 can generate an elastic pressure that restricts the auxiliary tool from swinging outwards, so as to prevent the auxiliary tool from swinging out non-artificially. When the user applies an outward pulling force to the auxiliary tool, the auxiliary tool can overcome the elastic pressure of the outer limiting member 801 and swing outwards, and the outer limiting member 801 elastically deforms in the direction of avoiding the outward swing of the auxiliary tool. The inner limiting member 802 is used to position the auxiliary tool that has swung in place and prevent the auxiliary tool from swinging inwards excessively.

[0035] Specifically, the outer limiting member 801 is a structure that can elastically stretch and deform or elastically bend and deform. For example, a spring or a sheet-like structure is adopted. Its free end is elastically abutted against the side surface of the handle part where the auxiliary tool is hinged. When the auxiliary tool is completely stored in the storage space, the outer limiting member 801 is substantially parallel to the handle. The outer limiting member 801 elastically abuts against the side surface of the handle part where the auxiliary tool is hinged, which can prevent the auxiliary tool from swinging out of the storage cavities 1010 and 2010 non-artificially. When the user applies an outward pulling force to the auxiliary tool, the auxiliary tool can overcome the elastic pressure of the outer limiting member 801 and swing outwards, and the outer limiting member 801 elastically deforms in the direction of avoiding the outward swing of the auxiliary tool.

[0036] Optionally, the outer limiting member 801 is integrally in a sheet-like structure. It is arranged in the storage cavities 1010 and 2010. One end of it is fixedly connected or clamped with the jaw handle to form a fulcrum for elastic deformation, and the other end is elastically abutted against the side surface of the handle part where the auxiliary tool is hinged.

[0037] In some embodiments, the outer limiting member 802 is in a rod-like structure. It is arranged in the storage cavities 1010 and 2010, and both ends are connected to the jaw handle (such as fixedly connected or clamped). Specifically, it can be a cylindrical, square-columnar, prismatic or irregular columnar structure. Of course, the outer limiting member 802 can also be a protruding structure integrally formed on the jaw handle.

[0038] In this embodiment, there are multiple embodiments for the structure and function of the jaw head. For example, at least one of the functional parts such as the pattern pressing part 901, the pipe pressing part 902, the flattening part 903, the shearing part 904, and the hook picking part 905 are formed by the cooperation between the first jaw head 102 and the second jaw head 202. The selection of the specific functional part can be considered according to practicality. The above functional structures are all prior arts and are well-known to those skilled in the art. The specific structures and working principles thereof will not be elaborated here.

[0039] In this embodiment, a locking structure 12 is provided between the first jaw 102 and the second jaw 202 to lock the first jaw 102 and the second jaw 202 in a closed state when not in use, thereby preventing the first jaw 102 and the second jaw 202 from being unfolded non-artificially. Specifically, the locking structure 12 includes a locking hook 121 and a locking groove 122. The locking groove is provided at the rear end of one of the first jaw 102 and the second jaw 202. One end of the locking hook 121 is hinged to the rear end of the other of the first jaw 102 and the second jaw 202 and can swing relative to the jaw, so that the free end of the locking hook 121 with a hook portion can swing between a position where it is inserted into the locking groove 122 and a position where it exits the locking groove 122. When the free end is inserted into the locking groove 122, the locking hook 121 hooks the groove wall of the locking groove 122 and locks the first jaw 102 and the second jaw 202. In some other embodiments, the locking structure 12 can also be replaced by a bolt pair passing through the locking groove 122 for the preferred embodiment. This is prior art and will not be elaborated.

[0040] Furthermore, the locking hook 121 is further convexly provided with a pulling portion 123 to facilitate the user to drive the locking hook 121 to swing.

[0041] Specifically, a reset member (not shown) is provided at the hinge joint of the first jaw 102 and the second jaw 202 to apply an elastic force to drive the first jaw 102 and the second jaw 202 to unfold, which is convenient for use. At the same time, when the locking hook 121 hooks the groove wall of the locking groove 122, the first jaw 102 and the first jaw 202 can drive the locking hook 121 to tightly hook the locking groove 122 under the elastic force of the reset member, thereby preventing the locking hook 121 from being separated from the locking groove 122 non-artificially.

[0042] Optionally, the reset member is an elastic member such as a torsion spring, a reed, or a tension spring. The elastic members such as torsion springs, reeds, or tension springs are all prior art, and the specific structures and installation methods will not be elaborated here.

[0043] In this embodiment, a lanyard hole 11 is provided on the first pliers handle 101 or the second pliers handle 201 for tying a hanging rope, which is convenient for carrying. It can be understood that the setting method of the lanyard hole 11 can be determined according to the use requirements. It can be formed on the pliers handle or formed by a hanging ring installed on the pliers handle. Specifically, the auxiliary tool and the hanging ring are installed at the rear part of the pliers handle through a hinge shaft 7. How to install it is prior art and will not be elaborated here.

[0044] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
