Description

Technical Field

[0001] This application relates to the field of hand tool technology, and more particularly to a multi-functional tool. Background Technology

[0002] Fasteners, such as bolts and screws, are essential basic components in mechanical manufacturing and equipment assembly. Their core function is to reliably fasten two or more parts together through threaded connections. To facilitate the application of torque for assembly and disassembly, the heads of these fasteners are usually designed with a polygonal structure, with the hexagon being the most commonly used shape due to its balance between lever arm and angle.

[0003] Based on the different force-applying structures during assembly and disassembly, hexagonal head fasteners are mainly divided into two categories: external hexagonal fasteners and internal hexagonal fasteners. External hexagonal fasteners have a hexagonal prism head, requiring tools such as open-end wrenches, box wrenches, or hex sockets to be used to tighten them by gripping the prism head from the outside. Internal hexagonal fasteners, on the other hand, have a recessed hexagonal blind hole at the head. During assembly and disassembly, the L-shaped shank of a suitable internal hexagonal wrench is inserted into the hole, and torque is applied through the longer arm of the wrench.

[0004] Whether it's an internal or external hex wrench, its handle or lever arm is typically designed to be relatively long to provide sufficient torque and facilitate operation. While this feature is advantageous for high-intensity tightening or disassembly work in fixed workplaces, it also results in a larger overall tool size, making it significantly inconvenient for everyday carrying. Utility Model Content

[0005] This application provides a multi-functional tool to solve the technical problem that hex wrench sets and screwdriver sets are not portable, inconvenient to carry, and unsuitable for daily use.

[0031] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Example 1

[0033] like Figure 1 and Figure 2 As shown, the multi-functional tool provided in this application embodiment includes a detachably connected first polyhedron 100 and a second polyhedron 200. At least one face of the first polyhedron 100 is provided with a first driving hole 110 that mates with the head of an external hexagonal fastener, and at least one face of the second polyhedron 200 is provided with a second driving protrusion 210 that mates with the hexagonal blind hole of the head of an internal hexagonal fastener. In other words, the first polyhedron 100 has a first driving hole 110 that mates with the head of an external hexagonal fastener, and the second polyhedron 200 has a second driving protrusion 210 that mates with the hexagonal blind hole of the head of an internal hexagonal fastener. The combination of the first polyhedron 100 and the second polyhedron 200 satisfies the simple daily needs for external and internal hexagonal wrenches. On the other hand, the detachable connection of the first polyhedron 100 and the second polyhedron 200 and the shape of the polyhedrons increase the playability of this multi-functional tool, increasing its usability while satisfying the user's daily carrying needs.

[0034] For example, the first driving hole can be a hexagonal hole, a pentagonal hole, a square hole, etc.

[0035] For example, the second driving convex can be a hexagonal convex, a square convex, etc.

[0036] For example, in this embodiment, for ease of processing, the first driving hole is set as a hexagonal hole, and the second driving protrusion is a hexagonal protrusion.

[0037] In some embodiments of this application, at least one of the first driving holes 110 is a first connecting hole 120, and at least one of the second driving protrusions 210 is a second connecting protrusion. The second connecting protrusion is detachably inserted into the first connecting hole 120. The first polyhedron 100 and the second polyhedron 200 are detachably connected through the mating insertion of the second connecting protrusion and the first connecting hole 120. That is, the second connecting protrusion and the first connecting hole 120 serve both as a wrench for fastening and as a connecting component for connecting the first polyhedron 100 and the second polyhedron 200. In the stored state, the second connecting protrusion is inserted into the first connecting hole 120 to connect the first polyhedron 100 and the second polyhedron 200. When using the second connecting protrusion to fasten internal hexagonal fasteners or using the first connecting hole 120 to fasten external hexagonal fasteners, the second connecting protrusion is pulled out of the first connecting hole 120, exposing the first connecting hole 120 and the second connecting protrusion. In other words, when the multi-functional tool is stored, the first connecting hole 120 and the second connecting protrusion are engaged and concealed. At this time, the first connecting hole 120 and the second connecting protrusion serve as the engagement structure for the first polyhedron 100 and the second polyhedron 200. When the multi-functional tool is in use, the first polyhedron 100 and the second polyhedron 200 are separated, exposing the first connecting hole 120 and the second connecting protrusion. At this time, the first connecting hole 120 and the second connecting protrusion serve as a wrench for assembling and disassembling hexagonal fasteners.

[0038] For example, in some embodiments of this application, at least one face of the second polyhedron 200 is provided with a second connecting hole 220, and at least one face of the first polyhedron 100 is provided with a first connecting protrusion 130 that mates with the second connecting hole 220. The first connecting protrusion 130 is detachably inserted into the second connecting hole 220. Figure 1 As shown, the second polyhedron 200 can be inserted into the first polyhedron 100 via a second connecting protrusion, as follows: Figure 3As shown, the first polyhedron 100 can be inserted into the second polyhedron 200 via the first connecting protrusion 130. This interlocking of the first polyhedron 100 and the second polyhedron 200 increases the playability of this multi-functional tool. Furthermore, when using the second connecting protrusion to install or remove internal hexagonal fasteners, or when using the first connecting hole 120 to install or remove external hexagonal fasteners, the first polyhedron 100 and the second polyhedron 200 are connected together via the first connecting protrusion 130 and the second connecting hole 220. At this time, the user can hold both polyhedra to install or remove internal or external hexagonal fasteners, thereby increasing the effective grip area, improving comfort during operation, facilitating force application, and reducing user fatigue. In addition, the interlocking of the first polyhedron 100 and the second polyhedron 200 prevents the loss of one while using the other.

[0039] In some embodiments of this application, the first connecting protrusion 130 is a hexagonal protrusion that mates with the hexagonal blind hole on the head of the internal hexagonal fastener. Correspondingly, the second connecting hole 220 that mates with the first connecting protrusion 130 is a hexagonal hole, adapted for disassembling and assembling external hexagonal fasteners. That is to say, the first connecting protrusion 130 and the second connecting hole 220 in the embodiments of this application serve both as a wrench for disassembling and assembling fasteners and as connecting components for connecting the first polyhedron 100 and the second polyhedron 200.

[0040] For example, there is one first connecting protrusion 130 and one second connecting protrusion. Both the first connecting protrusion 130 and the second connecting protrusion are hexagonal protrusions, and the types of internal hexagonal fasteners that the first connecting protrusion 130 and the second connecting protrusion are adapted to are different. That is to say, the multi-tool has two hexagonal protrusions that mate with the hexagonal blind holes of the internal hexagonal fastener heads. The two hexagonal protrusions are of different sizes, thereby enabling the multi-tool to adapt to two sizes of internal hexagonal fasteners. The first polyhedron 100 and the second polyhedron 200 are each provided with a hexagonal protrusion. The hexagonal protrusion is used to meet the mutual insertion requirements of the first polyhedron 100 and the second polyhedron 200. This structural method, while meeting the mutual insertion requirements of the first polyhedron 100 and the second polyhedron 200, makes the overall shape of the first polyhedron 100 and the second polyhedron 200 more regular and aesthetically pleasing.

[0041] like Figure 1 and Figure 3As shown, in some embodiments of this application, a first connecting protrusion 130 and one of the first connecting holes 120 are disposed on opposite sides of the first polyhedron 100, and a second connecting protrusion and one of the second connecting holes 220 are disposed on opposite sides of the second polyhedron 200. That is, when the user uses the first connecting protrusion 130 or the second connecting hole 220, the first polyhedron 100 and the second polyhedron 200 are connected via the second connecting protrusion and the first connecting hole 120, with the first connecting protrusion 130 and the second connecting hole 220 located at opposite ends of the first polyhedron 100 and the second polyhedron 200 in the splicing direction. When the user uses the second connecting protrusion and the first connecting hole 120, the first polyhedron 100 and the second polyhedron 200 are connected via the first connecting protrusion 130 and the second connecting hole 220, with the second connecting protrusion and the first connecting hole 120 located at opposite ends of the first polyhedron 100 and the second polyhedron 200 in the splicing direction. This structure increases the lever arm, making it easier for the user to apply force and grip.

[0042] For example, the first polyhedron 100, excluding the side with the first connecting protrusion 130, has first driving holes 110 on all other sides. The second polyhedron 200, excluding the side with the second connecting protrusion, has second driving holes 230 on all other sides. That is, one side of the first polyhedron 100 has the first connecting protrusion 130, and all other sides have first driving holes 110; the first driving hole 110 on the side opposite the first connecting protrusion 130 is called a first connecting hole 120. Similarly, one side of the second polyhedron 200 has the second connecting protrusion, and all other sides have second driving holes 230; the second driving hole 230 on the side opposite the second connecting protrusion is called a second connecting hole 220. The arrangement of multiple first driving holes 110 and multiple second driving holes 230 can accommodate a wider range of hexagonal fasteners.

[0043] For example, the second driving hole 230 can be a hexagonal hole, a star-shaped hole, a square hole, etc. In this embodiment, for ease of processing, the second driving hole 230 is set as a hexagonal hole.

[0044] For example, to make the multi-function tool more portable, both the first polyhedron 100 and the second polyhedron 200 have hollow interiors, forming a hollow cavity 140. The first drive hole 110 communicates with the hollow cavity 140 of the first polyhedron 100, and the second drive hole 230 communicates with the hollow cavity 140 of the second polyhedron 200. This structure reduces the overall weight of the multi-function tool, making it more portable. Furthermore, when installing or removing hexagonal fasteners from the first drive hole 110 and the second drive hole 230, the hexagonal head of the fastener extends into the hollow cavity 140, thereby reducing the wall thickness of the first drive hole 110 and the second drive hole 230 in the depth direction. This reduces the volume of the first polyhedron 100 and the second polyhedron 200, making them more compact and portable.

[0045] In some embodiments of this application, the second drive protrusion 210 is provided with a third drive hole 211 that mates with the head of the external hexagonal fastener. This structure further increases the number of hexagonal holes provided in the multi-function tool, enabling the multi-function tool to be configured with more sizes of hexagonal holes, thereby adapting to more specifications of external hexagonal fasteners.

[0046] For example, such as Figure 1 and Figure 2 As shown, the first polyhedron 100 is a cuboid or cube structure, and the second polyhedron 200 is a cuboid or cube structure. For example, the longest edge of the first polyhedron 100 and the second polyhedron 200 is no greater than 5 cm. For example, the longest edge of the first polyhedron 100 and the second polyhedron 200 is 2 cm, 2.5 cm, 3 cm, or 5 cm.

[0047] In some embodiments of this application, at least one of the first polyhedron 100 and the second polyhedron 200 has scale lines (not shown) on the edges of one or more of its edges. The scale lines enable the multi-functional tool to be used as a ruler for measuring dimensions.

[0048] In some embodiments of this application, the edges of the first polyhedron 100 and / or the second polyhedron 200 are provided with chamfered structures 150, one of which is provided with a file (not shown in the figure).

[0049] Example 2

[0050] The multi-functional tool provided in this embodiment is basically the same as the multi-functional tool provided in Embodiment 1, except that: Figure 4 and Figure 5 As shown, the multi-functional tool in this embodiment also includes a screw removal and assembly component 300.

[0051] Please continue reading. Figure 4 and Figure 5 In this embodiment, the first connecting protrusion 130 and the second connecting protrusion of the multi-functional tool are both provided with a third connecting hole 131, which is an irregularly shaped hole. The screw removal and installation component 300 includes a removal and installation component body 310, and both opposite sides of the removal and installation component body 310 are provided with third connecting protrusions 311. One of the two third connecting protrusions 311 is detachably inserted into one of the third connecting holes 131, and the other is detachably inserted into the other third connecting hole 131. At least one third connecting protrusion 311 is provided with a screwdriver head, which can pass through the third connecting hole 131 corresponding to the third connecting protrusion 311 where the screwdriver head is provided and extend into the corresponding polyhedron. That is to say, the multi-functional tool of this embodiment, in its stored and portable state, is as follows: Figure 4 As shown, the screw-removing component 300 is detachably connected between the first polyhedron 100 and the second polyhedron 200. Figure 6 and Figure 7 As shown, when using a screwdriver, one polyhedron is attached to another polyhedron, thus exposing the screwdriver head, allowing the multi-tool to be used as a screwdriver.

[0052] It should be noted that in this application, the screwdriver tip refers to the working head part of the screwdriver, which may exclude the shank or include a shorter shank. When the screwdriver tip is inserted into the polyhedron, the working end of the screwdriver tip will not protrude from the polyhedron.

[0053] For example, in some embodiments of this application, the third connecting hole 131 is a hexagonal hole that mates with the head of an external hexagonal fastener. This structure further increases the number of hexagonal holes provided by the multi-tool, enabling the multi-tool to be configured with more sizes of hexagonal holes, thereby adapting to more specifications of external hexagonal fasteners. Correspondingly, the third connecting protrusion 311 is a hexagonal protrusion, which can be adapted to install and remove internal hexagonal fasteners without a screwdriver head. For example, in some embodiments of this application, when a screwdriver head is provided on one of the two third connecting protrusions 311, the third connecting protrusion 311 without a screwdriver head serves as the hexagonal protrusion adapted to internal hexagonal fasteners. This structure further increases the number of hexagonal protrusions provided by the multi-tool, enabling the multi-tool to be configured with more sizes of hexagonal protrusions, thereby adapting to more specifications of internal hexagonal fasteners. For example, in some other embodiments of this application, both third connecting protrusions 311 are provided with screwdriver bits, one of which is a flathead screwdriver bit 312 and the other is a Phillips head screwdriver bit 313. On the one hand, the flathead screwdriver bit 312 and the Phillips head screwdriver bit 313 are commonly used screwdriver bits, which can basically meet the user's simple daily needs. On the other hand, the flathead screwdriver bit 312 can also be used as a knife for unpacking packages, increasing the functionality of this multi-functional tool. For example, one way to use this multi-functional tool is as follows... Figure 6 As shown, the second polyhedron 200 is attached to the first polyhedron 100, exposing a Phillips head screwdriver. Another attachment method is as follows: Figure 7 As shown, the first polyhedron 100 is attached to the second polyhedron 200, revealing a flathead screwdriver.

[0054] like Figure 5 As shown, in some embodiments of this application, an annular groove 315 is provided on the circumferential side of the third connecting protrusion 311 of the screwdriver tip, and a rubber ring 316 is provided in the annular groove 315. The rubber ring 316 makes the splicing of the screw assembly 300 with the first polyhedron 100 or the second polyhedron 200 more stable.

[0055] Please continue reading. Figure 5 In some embodiments of this application, the main body 310 of the detachable component is a plate-like structure. At least one side of the plate-like structure is provided with a blocking edge 320 extending to both sides in the thickness direction of the plate-like structure. A file (not shown in the figure) is provided on the side of the blocking edge 320 facing away from the plate-like structure. Exemplarily, the plate-like structure may have blocking edges 320 on two opposite sides. Exemplarily, the plate-like structure may also have blocking edges 320 on each side.

[0056] For example, the dimension of the obscuring edge 320 in the thickness direction of the plate-like structure matches the distance between the first polyhedron 100 and the second polyhedron 200. The obscuring edge 320 obscures the area between the first polyhedron 100 and the second polyhedron 200, increasing the aesthetics of the multi-functional tool.

[0057] In some embodiments of this application, such as Figure 4 As shown, the main body 310 of the detachable component is provided with a suspension structure 314. For example, the suspension structure 314 is a suspension ring, which allows the user to hang the multi-tool on a key ring for easy carrying.

[0058] Example 3 The multi-functional tool provided in this embodiment includes a first polyhedron 100 and a second polyhedron 200. The first polyhedron 100 has a first driving hole 110, i.e., a first connecting hole 120, on only one side, and the second polyhedron 200 has a second driving protrusion 210, i.e., a second connecting protrusion, on only one side. The second connecting protrusion is detachably inserted into the first connecting hole 120 so that the first polyhedron 100 and the second polyhedron 200 can be detachably connected. When the multi-tool is stored, the first connecting hole 120 and the second connecting protrusion are inserted and concealed. The other faces of the first polyhedron 100 and the second polyhedron 200 can be decorated with patterns, etc., so that the multi-tool can be a portable decorative item when stored. When an internal or external hex wrench is needed, the first polyhedron 100 and the second polyhedron 200 can be separated to expose the first connecting hole 120 and the second connecting protrusion for use as an external or internal hex wrench. In addition, after the two polyhedra are inserted, the user can hold and play with them, or disassemble and assemble the two polyhedra to play with them, making the multi-tool highly playable.
