Description

Technical Field

[0001] This utility model belongs to the field of manual tool technology, specifically relating to a multi-functional pliers. Background Technology

[0002] Multi-tools achieve multiple functions by being equipped with auxiliary tools. To facilitate portability, existing multi-tools usually have hanging holes on their handles, which increases the length of the handles and makes the overall multi-tools larger. Utility Model Content

[0003] This invention addresses the shortcomings of existing multi-functional pliers, which have long handles and large overall size, by providing a compact multi-functional pliers.

[0004] To achieve the above objectives, the multi-functional pliers of this utility model include a first pliers head and a second pliers head that are crossed and pivotally connected. The end of the first pliers head away from the jaws is rotatably connected to a first handle via a first pin. The end of the second pliers head away from the jaws is rotatably connected to a second handle via a second pin. The first handle and / or the second handle are equipped with an auxiliary tool that can be unfolded and stored. The feature is that the end of the first handle away from the first pin is movably equipped with a hook that can be stored in the first handle and extend from the first handle.

[0005] This multi-functional pliers allows the hook to be removed from the first handle when needed, and stored back inside the first handle when not in use, without taking up length of the first handle. Therefore, when storing the hook, the first handle remains relatively short, and the second handle, which matches the first handle, also remains relatively short, thus keeping the entire multi-functional pliers compact. Folding the first and second handles and storing the two pliers heads inside the first handle further highlights the compact size of the entire multi-functional pliers.

[0006] In one embodiment, the hook is slidably fitted to the first handle to facilitate the hook being retracted into and extended from the first handle.

[0007] Preferably, the hook has a first track surface and a guide post, and the first handle has a second track surface and a guide hole. The first track surface and the second track surface are slidably engaged, and the guide post is located in the guide hole to maintain the slidable engagement between the first track surface and the second track surface. Therefore, the first track surface and the second track surface always maintain a slidable engagement and will not disengage, allowing the hook to slide smoothly under external force.

[0008] Preferably, the first handle includes a first handle body and an inner support located within the first handle body. A second track surface is located within the inner support, which has a positioning post located in a guide hole. The first handle body and the inner support are connected by a first pin at their ends away from the first pin shaft. By means of the constraint of the positioning post by the guide hole and the constraint of the inner support by the first pin, the inner support is fixed within the first handle. Furthermore, the inner support supports the first handle within the first handle, resisting deformation of the first handle when subjected to external forces. As an assembly component, the inner support is easily machined to have a second track surface, thereby mates with the first track surface to guide the hook to slide smoothly.

[0009] Preferably, the hook has a protrusion, and the first handle has a first recess and a second recess. When the hook is retracted into the first handle, the protrusion sinks into the first recess; when the hook extends from the first handle, the protrusion sinks into the second recess. Therefore, the hook can be positioned as needed without accidental misalignment.

[0010] Preferably, the hook is ring-shaped, and a first pin is provided at the end of the first handle away from the first pin shaft, with the first pin located inside the ring of the hook. The first pin strengthens the rigidity of the end of the first handle away from the first pin shaft, while the ring-shaped hook can slide and change position by avoiding the obstruction of the first pin.

[0011] Preferably, the first handle has a notch, through which the hook is exposed, so that the finger can push the hook to move.

[0012] Preferably, the auxiliary tools are rotatably mounted on the corresponding handle. Users can rotate and unfold the required auxiliary tools as needed for use.

[0013] Preferably, the first or second handle includes a handle body and an inner support located within the handle body. The handle body has an opening on its side, and the inner support has a storage slot. One end of the storage slot corresponds to the opening and is provided with a guide surface. An elastic tool is stored in the storage slot, and the elastic tool is placed in the storage slot through the opening and removed from the storage slot by the guidance of the guide surface.

[0014] Preferably, one end of the elastic tool protrudes from the opening and has a step at the protruding part. When taking out the tweezers, the tweezers can be pulled out from the receiving groove by holding the step with your hand.

[0015] In another embodiment, the hook is rotatably fitted to the first handle so that the hook can be retracted into and unfolded from the first handle by rotation.

[0016] Preferably, the first handle body of the first handle and the second handle body of the second handle are both formed by bending metal sheets to create a receiving groove, in which the auxiliary tools are housed. This structure provides sufficient strength and rigidity for the first and second handles while maintaining a compact and small design.

[0017] This utility model features a hook that can be retracted into and extends from the handle at one end of the handle away from the first pin. When the hook is needed, it can be removed from the handle; when not needed, it can be retracted into the handle for storage, without taking up the length of the handle. Therefore, when the hook is stored, the two matching handles also maintain a short length, thus keeping the entire multi-functional pliers compact. Folding the two handles and storing the two pliers heads in the two handles further enhances the compact size of the entire multi-functional pliers. Attached Figure Description

[0023] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0024] Figure 1-9 A multi-functional pair of pliers is shown, comprising a first jaw 100 and a second jaw 200 that cross each other and are connected by a pivot 300. The end of the first jaw 100 away from the jaws is rotatably connected to a first handle 400 via a first pin 401. The end of the second jaw 200 away from the jaws is rotatably connected to a second handle 500 via a second pin 501. The first handle body 405 of the first handle 400 and the second handle body of the second handle 400 are both formed by bending metal sheets to form receiving grooves 402. Figure 1In this design, both the first and second handles have receiving grooves facing left and right. The first and second handles of this structure have sufficient strength and rigidity while maintaining a compact and small design.

[0025] exist Figure 1 In the shown state, by unfolding the first handle 400 and the second handle 500 relative to each other, the first jaw 100 and the second jaw 200 can be opened. When the first jaw and the second jaw are open, by gripping the first handle and the second handle relative to each other, the first jaw and the second jaw can be brought together to clamp tightly.

[0026] exist Figure 1 In the indicated state, the first handle 400 rotates clockwise around the first pin 401, and the second handle 500 rotates counterclockwise around the second pin 501, allowing the first handle 400 and the second handle 500 to be rotated as shown. Figure 2 The first pliers head 100 is placed into the receiving slot of the second handle 500, and the second pliers head 200 is placed into the receiving slot of the first handle 400. The first handle 400 and the second handle 500 are placed side by side, so that the entire multi-functional pliers are in a position where... Figure 2 The folded state shown is relative to Figure 1 When unfolded, it can occupy a smaller volume.

[0027] Given that the first pliers head 100 and the second pliers head 200 are arranged symmetrically from left to right, the first handle body 400 and the second handle body 500 and their receiving grooves are also arranged symmetrically from left to right.

[0028] The first handle 400 and the second handle 500 are equipped with expandable and retractable auxiliary tools, such as... Figure 4 As shown, rotate the cutting blade 701 to extend the second handle 500, as... Figure 5 As shown, rotate the scissors 702 to extend the first handle 400, as indicated. Figure 6 The tweezers 703, which serve as a flexible tool, are removed from the first handle 400, as shown. Figure 7 The bottle opener 704 and screwdriver 705 are shown rotating to extend the second handle 500. The cutting knife, scissors, tweezers, bottle opener, and screwdriver are collectively referred to as auxiliary tools. In other embodiments, these auxiliary tools may be replaced or added.

[0029] Some of the auxiliary tools are rotatably mounted on corresponding handles, allowing users to unfold and use the desired tools as needed. For example, a cutting knife 701, scissors 702, bottle opener 704, and screwdriver 705 are rotatably mounted to their respective handles via pins and are stored in and unscrewed from their respective receiving slots. Figure 4 As shown, rotating the cutting blade 701 counterclockwise allows it to be retracted into the receiving slot of the second handle, as... Figure 5 As shown, rotating the scissors 702 clockwise will retract them into the receiving slot of the first handle. Figure 7The bottle opener 704 and screwdriver 705 can be retracted into the receiving slot of the second handle by rotating them counterclockwise.

[0030] Among them, such as Figure 8-9 As shown, the first handle 400 includes a first handle body 405 and an inner support 406 located within the first handle body. The rear side of the first handle body 405 has an opening 412. The inner support 406 has a rearward-facing storage slot 413. One end of the storage slot 413 corresponds to the opening 412 and is provided with a guide surface 414, which is an inclined surface. Tweezers 703 are stored in the storage slot 413. Guided by the guide surface 414, the tweezers 703 are placed in and removed from the storage slot 413 through the opening 412. To facilitate the removal of the tweezers, one end of the tweezers 703 protrudes from the opening 412, and a step 706 is provided at the protruding part. When removing the tweezers, the step 706 can be gripped by hand to pull the tweezers out of the storage slot 413. When the tweezers are stored in the storage slot, the elastic deformation of the tweezers themselves ensures that the tweezers will not fall out of the storage slot. Similar tools with elastic deformation capabilities can replace the tweezers. In other embodiments, the tweezers can be stored in a second handle.

[0031] In particular, the end of the first handle 400 that is furthest from the first pin 401 ( Figure 1 The lower end shown Figure 2 The upper part (as shown) has the following active configurations. Figure 1 The first handle and shown are included Figure 3 The hook 600 extends from the first handle 400. When the hook 600 is needed, it can be removed from the first handle; when not in use, it can be stored back inside the first handle without taking up length of the first handle. Therefore, when the hook is stored, the first handle remains relatively short, and the second handle, when paired with the first handle, also remains relatively short, thus keeping the entire multi-tool compact. Folding the first and second handles and storing the two pliers heads within the first handle further emphasizes the compact size of the entire multi-tool.

[0032] The above structure embodies the basic concept of this utility model: a movable hook to shorten the length of the first handle, thus enabling the realization of the technical solution of this utility model. To further improve the clamping and positioning device, the following preferred technical means can be used to obtain a better embodiment based on the above structure.

[0033] In the illustrated embodiment, the hook 600 is slidably fitted onto the first handle 400 to facilitate the retraction of the hook 600 into and out of the first handle 400.

[0034] like Figure 8-9As shown, the hook 600 has a first track surface 601 and a guide post 602, and the first handle 400 has a second track surface 403 and a guide hole 404. The first track surface 601 and the second track surface 403 are slidably engaged. The guide post 602 is located within the guide hole 404 to prevent the hook from flipping, thus maintaining the slidable engagement between the first track surface 601 and the second track surface 403. Therefore, the first track surface 601 and the second track surface 403 always maintain a slidable engagement and will not disengage, allowing the hook to slide smoothly under external force. In the illustrated structure, the first track surface 601 is a concave corner surface, and the second track surface 403 is a convex corner surface. Therefore, when the first track surface and the second track surface are in contact, they can fit together to guide the hook to slide.

[0035] like Figure 8-9 As shown, the first handle 400 includes a first handle body 405 and an inner support 406 located within the first handle body. A second track surface 403 is located within the inner support 406. The inner support 406 has a positioning post 407. The positioning post 407 is located at one end of the guide hole 404 and does not obstruct the sliding of the guide post 602 within the guide hole 404. The first handle body 405 and the inner support 406 are pinned together by a first pin 408 at their ends away from the first pin shaft 401. Through the constraint of the first pin 408 on the inner support 406 and the constraint of the guide hole 404 on the positioning post 407, the inner support 406 is fixed within the first handle body 405. Furthermore, the inner support 406 supports the first handle body within the first handle body, resisting deformation of the first handle body when subjected to external forces. Further, a pad 415 is placed in another receiving groove of the first handle body. This pad also supports the first handle body, resisting deformation of the first handle body when subjected to external forces. As an assembly component, the inner bracket 406 is easy to machine into a second track surface, which can then cooperate with the first track surface to guide the hook to slide smoothly.

[0036] like Figure 8-9 As shown, the hook 600 has a protrusion 603, and the first handle 400 has a first recess 409 and a second recess 410. Specifically, the inner support 406 is a component of the first handle 400, and the first recess 409 and the second recess 410 are located in the inner support. The hook 600 is as follows: Figure 1 When the first handle 400 is inserted, the protrusion 603 sinks into the first recess 409, and the hook 600 is as shown. Figure 3 As shown, when the protrusion 603 extends from the first handle 400, it sinks into the second recess 410. Accordingly, the hook can be positioned as needed without accidentally becoming misaligned.

[0037] like Figure 8-9 As shown, the hook 600 is ring-shaped, and the end of the first handle 400 away from the first pin 401 is provided with a first pin 408, which is located inside the ring of the hook 600. The first pin strengthens the rigidity of the end of the first handle away from the first pin, while the ring-shaped hook can slide and change position by avoiding the obstruction of the first pin.

[0038] like Figure 8 As shown, the first handle 400 has a notch 411, and the hook 600 is as follows. Figure 1 The hook is shown to be exposed at notch 411 when it is stored in the first handle, so that the fingers can push the hook to move.

[0039] In another embodiment, the hook 600 can be rotatably mounted to the first handle, like a cutter, scissors, bottle opener, or screwdriver. This allows the hook to be retracted into and unfolded from the first handle by rotation.
