[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] The multifunctional pliers 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] Reference Figures 1-10 The multifunctional pliers 100 according to an embodiment of the present invention include: a pliers body 1, an adapter sleeve 2 and an external tool 3. There are two pliers bodies 1, and the two pliers bodies 1 are rotatably connected by a rotating shaft 13. In the extension direction of the pliers body 1, the parts of the pliers body 1 located on both sides of the rotating shaft 13 are respectively the handle part 11 and the pliers head part 12, that is, the handle part 11 and the pliers head part 12 are located on both sides of the rotating shaft 13.

[0040] Reference Figure 7The pliers head 12 is provided with an assembly hole 121, which extends along the extension direction of the pliers body 1, and the outer contour of the cross section of the assembly hole 121 is non-circular; for example, the outer contour of the cross section of the assembly hole 121 can be a triangle, square, rectangle, hexagon or semicircle.

[0041] Reference Figure 7 The adapter sleeve 2 is inserted into the assembly hole 121, and the outer contour of the cross section of the adapter sleeve 2 matches the outer contour of the cross section of the assembly hole 121. For example, when the outer contour of the cross section of the assembly hole 121 is triangular, the outer contour of the cross section of the adapter sleeve 2 is triangular; when the outer contour of the cross section of the assembly hole 121 is hexagonal, the outer contour of the cross section of the adapter sleeve 2 is hexagonal; when the outer contour of the cross section of the assembly hole 121 is semicircular, the outer contour of the cross section of the adapter sleeve 2 is semicircular.

[0042] The adapter sleeve 2 defines an adapter hole 21 , and the outer contour of the cross section of the adapter hole 21 is non-circular; for example, the outer contour of the cross section of the adapter hole 21 can be triangular, square, rectangular, hexagonal or semicircular.

[0043] Reference Figure 7-10 There is at least one external tool 3. Specifically, there can be one, two, three, four, five, six, seven, or more external tools 3. The external tool 3 includes an adapter portion 31 and a tool head 32. The adapter portion 31 is inserted into the adapter hole 21. The outer contour of the cross section of the adapter portion 31 matches the outer contour of the cross section of the adapter hole 21. The tool head 32 is connected to the end of the adapter portion 31 away from the handle portion 11.

[0044] For example, when the outer contour of the cross section of the adapter hole 21 is a triangle, the outer contour of the cross section of the adapter portion 31 is a triangle; when the outer contour of the cross section of the adapter hole 21 is a hexagon, the outer contour of the cross section of the adapter portion 31 is a hexagon; when the outer contour of the cross section of the adapter hole 21 is a semicircle, the outer contour of the cross section of the adapter portion 31 is a semicircle.

[0045] For example, the tool head 32 can be used to realize the functions of one of the following: circlip pliers (inward), a Phillips screwdriver, a flat-blade screwdriver, an internal hexagonal wrench 61, and an external hexagonal wrench 61. Optionally, there can be multiple external tools 3, and the multiple external tools 3 are used to realize the functions of the circlip pliers (inward), a Phillips screwdriver, a flat-blade screwdriver, an internal hexagonal wrench 61, and an external hexagonal wrench 61 respectively.

[0046] When maintenance personnel need to perform maintenance, they can select the external tool 3 with a tool head 32 having the corresponding maintenance function according to the maintenance tools required for maintenance, insert the adapter part 31 of the external tool 3 into the adapter hole 21 of the adapter sleeve 2, and then insert the adapter sleeve 2 into the assembly hole 121 to complete the assembly of the external tool 3, thereby realizing the conversion of the multi-function pliers 100 from the pliers body function to the corresponding maintenance function.

[0047] Specifically, when maintenance personnel need to remove a cross screw, they can select the tool head 32 with a cross screwdriver function as the external tool 3 for this maintenance operation to realize the conversion of the multifunctional pliers 100 from the pliers body function to the cross screwdriver function.

[0048] When the maintenance personnel need to remove a slotted screw, the maintenance personnel can select the tool head 32 with the slotted screwdriver function as the external tool 3 for this maintenance operation to realize the conversion of the multifunctional pliers 100 from the pliers body function to the slotted screwdriver function.

[0049] When maintenance personnel need to remove the hexagonal bolt, they can select the tool head 32 with the function of the hexagonal wrench 61 as the external tool 3 for this maintenance operation to realize the conversion of the multifunctional pliers 100 from the pliers body function to the hexagonal wrench 61 function.

[0050] When the maintenance personnel need to remove the hexagon socket bolt, the maintenance personnel can select the tool head 32 with the function of the hexagon socket wrench 61 as the external tool 3 for this maintenance operation to realize the conversion of the multifunctional pliers 100 from the pliers body function to the hexagon socket wrench 61 function.

[0051] When the maintenance personnel need to remove and assemble the circlip outside the shaft, the maintenance personnel can select the tool head 32 with the circlip pliers (inward) function as the external tool 3 for this maintenance operation to realize the conversion of the multi-function pliers 100 from the pliers body function to the circlip pliers (inward) function.

[0052] According to the multifunctional pliers 100 of the present invention, by providing an adapter sleeve 2 to connect the pliers body 1 and the external tool 3, the pliers body 1 can realize the functions of different maintenance tools through the external tool 3, so that maintenance personnel do not need to carry a large number of maintenance tools, so that the number of maintenance tools carried by maintenance personnel is reduced, effectively reducing the weight of the tools carried by maintenance personnel and reducing the work intensity of maintenance personnel.

[0053] Reference Figure 7According to some embodiments of the present invention, the adapter sleeve 2 includes a first barrel wall 22 and a second barrel wall 23, which are arranged in the circumferential direction of the adapter sleeve 2. The first barrel wall 22 and the second barrel wall 23 are detachably connected. For example, the first barrel wall 22 and the second barrel wall 23 can be connected by a snap fastener, or the first barrel wall 22 and the second barrel wall 23 can be connected by a pin.

[0054] The first cylinder wall 22 and the second cylinder wall 23 together define the transfer hole 21. Specifically, the first cylinder wall 22 can be recessed in a direction away from the second cylinder wall 23 to form a first groove, and the second cylinder wall can be recessed in a direction away from the first cylinder wall 22 to form a second groove. The first groove and the second groove function as the transfer hole 21.

[0055] When it is necessary to connect the external tool 3, the first tube wall 22 and the second tube wall 23 can be disassembled first, and the adapter part 31 of the external tool 3 can be placed between the first tube wall 22 and the second tube wall 23. Then, the first tube wall 22 and the second tube wall 23 are used to clamp the adapter part 31 of the external tool 3, and the first tube wall 22 and the second tube wall 23 are connected together to complete the connection between the adapter sleeve 2 and the external tool 3.

[0056] When the external tool 3 is not needed, the first tube wall 22 and the second tube wall 23 can be disassembled, the external tool 3 can be taken out from the adapter hole 21, and then the first tube wall 22 and the second tube wall 23 can be connected together, and then the adapter sleeve 2 and the external tool 3 can be placed in their respective storage positions.

[0057] By arranging the first tube wall 22 and the second tube wall 23 to be detachably connected, the adapter sleeve 2 and the external tool 3 can be assembled and fitted by disassembling the first tube wall 22 and the second tube wall 23 .

[0058] For example, refer to Figure 7 and Figure 10 The adapter part 31 is provided with limiting protrusions 33 at both ends in its extension direction. The limiting protrusions 33 protrude from the adapter part 31 in the radial direction of the adapter part 31. The adapter sleeve 2 is arranged between the two limiting protrusions 33, and the two ends of the adapter sleeve 2 in the axial direction are respectively stopped by the two limiting protrusions 33.

[0059] In this way, the mutual limitation between the two limiting protrusions 33 and the adapter sleeve 2 can realize the axial limitation of the external tool 3 by the adapter sleeve 2, so that the external tool 3 can be kept fixed relative to the pliers body 1, reducing the risk of the external tool 3 shaking during use and improving the reliability of the multi-function pliers 100.

[0060] In some embodiments of the present invention, the two ends of the first cylinder wall 22 in the circumferential direction of the adapter sleeve 2 are respectively the first end and the second end, and the two ends of the second cylinder wall 23 in the circumferential direction of the adapter sleeve 2 are respectively the third end and the fourth end, and the first end and the third end are rotatably connected, for example, the first end and the second end can be connected by a pin shaft.

[0061] The second end is connected to the fourth end. For example, the second end and the fourth end may be connected by abutment, or may be connected by a snap-fit ​​structure, or may be connected by a fastener.

[0062] When it is necessary to transfer the external tool 3 through the transfer sleeve 2, the second tube wall 23 can be rotated relative to the first end to open the transfer hole 21, and the transfer part 31 of the external tool 3 can be placed between the first tube wall 22 and the second tube wall 23 through the gap between the second end and the fourth end. After that, the first end is fixed, the second tube wall 23 is rotated, and the transfer hole 21 is closed to complete the connection between the transfer sleeve 2 and the external tool 3.

[0063] When it is necessary to remove the external tool 3 from the adapter sleeve 2, the second cylinder wall 23 can be rotated relative to the first end to open the adapter hole 21, and the external tool 3 can be taken out of the adapter hole 21 through the gap between the second end and the fourth end. After that, the first end is fixed, the second cylinder wall 23 is rotated, the adapter hole 21 is closed, and the adapter sleeve 2 and the external tool 3 are placed in their respective storage positions.

[0064] By rotatably connecting the first end and the third end, the adapter sleeve 2 can open and close the adapter hole 21 by relatively rotating the first cylinder wall 22 and the second cylinder wall 23. When opening the adapter hole 21, there is no need to completely disassemble the first cylinder wall 22 and the second cylinder wall 23, which facilitates the disassembly and assembly of the adapter sleeve 2 and reduces the workload of maintenance personnel.

[0065] In some specific embodiments of the present invention, the second end and the fourth end are connected via a snap-fit ​​structure. For example, one of the second end and the fourth end may be provided with a snap-fitting groove, while the other may be provided with a snap-fitting protrusion. This ensures a secure connection between the second and fourth ends, allowing the adapter sleeve 2 to securely connect to the adapter portion 31 of the external tool 3, reducing the risk of the adapter sleeve 2 or the external tool 3 falling during movement. Furthermore, the snap-fit ​​structure facilitates assembly and disassembly.

[0066] In some specific embodiments of the present invention, the second end and the fourth end are connected by a fastener. For example, the fastener may be a bolt. This ensures a secure connection between the second end and the fourth end, allowing the adapter sleeve 2 to be securely connected to the adapter portion 31 of the external tool 3. This reduces the risk of the adapter sleeve 2 or the external tool 3 falling when moving, thereby improving the reliability of the multifunctional pliers 100.

[0067] Reference Figure 7 In other embodiments of the present invention, the cross-sectional area of ​​the assembly hole 121 gradually decreases toward the handle portion 11. This allows the adapter sleeve 2 to be inserted deeper into the adapter hole so that the outer surface of the adapter sleeve 2 abuts against the inner surface of the assembly hole 121, reducing the risk of the adapter sleeve 2 shaking in the assembly hole 121 and improving the stability of the multifunctional pliers 100.

[0068] For example, when the adapter sleeve 2 includes a first tube wall 22 and a second tube wall 23, the first tube wall 22 and the second tube wall 23 are arranged in the circumferential direction of the adapter sleeve 2, the two ends of the first tube wall 22 in the circumferential direction of the adapter sleeve 2 are respectively the first end and the second end, the two ends of the second tube wall 23 in the circumferential direction of the adapter sleeve 2 are respectively the third end and the fourth end, and the second end and the fourth end are abutted and connected, or the second end and the fourth end are connected by a snap-fit ​​structure. During the process of inserting the adapter sleeve 2 inward, the inner wall of the assembly hole 121 can gradually squeeze the first tube wall 22 and the second tube wall 23 toward the radial inner side, so that the first tube wall 22 and the second tube wall 23 can more reliably clamp the adapter part 31, further improving the reliability of the multi-function pliers 100.

[0069] Reference Figure 7 According to some optional embodiments of the present invention, a first magnetic component 41 is provided in the assembly hole 121, and a second magnetic component 42 is provided on the adapter sleeve 2. For example, the first magnetic component 41 can be a magnet, or the first magnetic component 41 can also be a magnetic metal component; when the first magnetic component 41 is a magnetic metal component, the first magnetic component 41 can be an iron component, a cobalt component, a nickel component, or an alloy component containing iron, cobalt, and nickel.

[0070] The first magnetic member 41 and the second magnetic member 42 are magnetically coupled. For example, when the first magnetic member 41 is a magnet, the second magnetic member 42 can be a magnet, or a magnetic metal member. Specifically, when the second magnetic member 42 is a magnetic metal member, the second magnetic member 42 can be iron, cobalt, nickel, or an alloy containing iron, cobalt, and nickel. When the first magnetic member 41 is a magnetic metal member, the second magnetic member 42 is a magnet.

[0071] In this way, the first magnetic part and the second magnetic part can be attracted to each other to fix the adapter sleeve 2 to the caliper body 1, so that the adapter sleeve 2 can be reliably fixed relative to the caliper body 1. The magnetic attraction setting facilitates the insertion and removal of the adapter sleeve 2, which can effectively reduce the workload of maintenance personnel.

[0072] Optionally, the caliper body 1 and the adapter sleeve 2 may also be fixed by a pin extending radially along the adapter sleeve 2, so that the axial limiting and unlocking between the caliper body 1 and the adapter sleeve 2 can be achieved by plugging and pulling out the pin.

[0073] Optionally, an elastic clip can be provided in the assembly hole 121, and a limiting groove can be provided on the radial outer surface of the adapter sleeve 2. The elastic clip is used to insert into the limiting groove when the adapter sleeve 2 is inserted into the assembly hole 121, so as to position the adapter sleeve 2 relative to the caliper body 1 in the axial direction of the adapter sleeve 2. In this way, the elastic clip can be squeezed by plugging and unplugging the adapter sleeve 2 to achieve axial limitation and unlocking between the caliper body 1 and the adapter sleeve 2.

[0074] Reference Figures 1-6 、 Figure 10 According to some alternative embodiments of the present invention, the tool head 32 of at least one external tool 3 intersects the extension direction of the adapter portion 31. This can change the operating direction of the pliers body 1, allowing the multifunctional pliers 100 to be used in environments where the axial space for the tool head 32 is small. This can also increase the torque of the tool head 32, effectively saving maintenance personnel effort and facilitating maintenance.

[0075] Reference Figure 8 and Figure 9 According to some alternative embodiments of the present invention, the tool head 32 of at least one external tool 3 extends in the same direction as the adapter portion 31. This facilitates the rotation of the tool head 32, reduces the space occupied by the pliers body 1 during rotation, and enables the multifunctional pliers 100 to be used in environments where the radial space around the tool head 32 is small.

[0076] Reference Figures 1-6 According to some specific embodiments of the present invention, a wire cutter opening 51 is provided on the pliers head 12, and the wire cutter openings 51 on the two pliers head 12 are arranged opposite to each other. When the two pliers head 12 stop, the toothed surfaces of the two wire cutter openings 51 engage with each other; in this way, the multifunctional pliers 100 can function as wire cutters through the two wire cutter openings 51.

[0077] Reference Figures 1-6 According to some specific embodiments of the present invention, the pliers head 12 is provided with diagonal jaws 52. The diagonal jaws 52 on the two pliers heads 12 are arranged opposite each other. When the two pliers heads 12 stop, the two diagonal jaws 52 stop. In this way, the multifunctional pliers 100 can function as diagonal pliers through the two diagonal jaws 52.

[0078] Reference Figures 1-6 According to some other specific embodiments of the present invention, at least one of the two handles 11 is provided with a wrench 61 ; this allows the multifunctional pliers 100 to have the function of the wrench 61 .

[0079] Reference Figures 1-6According to some other specific embodiments of the present invention, one of the two handle portions 11 is provided with a receiving groove 111, and the handle portion 11 provided with the receiving groove 111 is provided with an electrician's knife 62, and the electrician's knife 62 is rotatably connected to the corresponding handle portion 11, and can be screwed into and out of the receiving groove 111 by rotation; in this way, the multi-functional pliers 100 can have the function of a cutting tool, and the receiving groove 111 can be used to store the electrician's knife 62, thereby preventing the electrician's knife 62 from scratching maintenance personnel, thereby improving the safety of the multi-functional pliers 100.

[0080] Reference Figures 1-6 According to other specific embodiments of the present invention, one of the two handles 11 is provided with a first wire stripping jaw 63, and the other is provided with a second wire stripping jaw 64. The first wire stripping jaw 63 includes a plurality of first tooth structures, and the second wire stripping jaw 64 includes a plurality of second tooth structures. The first wire stripping jaw 63 and the second wire stripping jaw 64 are arranged opposite each other. When the two pliers heads 12 abut, the tooth tops of the first tooth structures abut against the tooth tops of the second tooth structures. This allows the multifunctional pliers 100 to function as wire strippers by combining the first wire stripping jaw 63 and the second wire stripping jaw 64.

[0081] Reference Figures 1-6 According to some other specific embodiments of the present invention, one of the two handles 11 is provided with a wire crimping groove 65, and the other is provided with a wire crimping protrusion 66. The wire crimping groove 65 and the wire crimping protrusion 66 are arranged opposite to each other. When the two pliers heads 12 stop at each other, the wire crimping protrusion 66 is inserted into the wire crimping groove 65.
