Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware tools technology, and more specifically, to a tool with an auxiliary locking structure. Background Technology
[0002] Currently, most multi-tool pliers or shears sold on the market use a locking mechanism with a spring or metal bar at the front of the handle to lock the opening and closing of the pliers or shears. When the handle is closed, this mechanism may have insufficient spring force in the spring or metal bar, causing the handle to fail to lock, resulting in the handle popping open or having play in the handle. This affects the storage of the product and may also lead to safety hazards. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of existing multi-functional tools that cannot be locked when the handle is closed, and to provide a tool with an auxiliary locking structure that makes it difficult to open the handle when it is closed, reduces handle play, and prevents the handle from popping open and causing parts to be exposed on the handle surface, thereby eliminating safety hazards.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A tool with an auxiliary locking structure is provided, comprising a first functional part and a second functional part hinged to each other, and a first handle and a second handle, wherein the first handle is hinged to the first functional part, and the second handle is hinged to the second functional part, and the first functional part and the second functional part can be rotated and folded relative to the first handle and the second handle and stored inside the first handle and the second handle; it also includes a locking structure, wherein the locking structure is installed at the end of the first handle and can abut or lock with the end of the second handle, and / or the locking structure is installed at the end of the second handle and can abut or lock with the end of the first handle.
[0006] This invention features a first functional part and a second functional part hinged together. The opening and closing of these parts enables the corresponding functions. The first and second functional parts can be pliers heads or scissor blades, thus achieving the function of pliers or scissors. A first handle is hinged to the first functional part, and a second handle is hinged to the second functional part. By gripping and applying force to the handles, the first and second functional parts can be opened and closed. Furthermore, the first and second functional parts can rotate and fold relative to the first and second handles, allowing them to be stored inside the handles when not in use and unfolded when needed. A locking structure is installed at the tail end of the first or second handle to lock the handle in the folded state, making it difficult to open when closed, reducing handle play, and preventing the first or second functional part from being exposed on the surface of the handle, thus eliminating safety hazards. Specifically, the locking structure abuts or engages with the tail end of the first or second handle to achieve its locking function.
[0007] Furthermore, it also includes a third functional part, and the locking structure can abut or engage with the third functional part; when the locking structure is installed at the end of the first handle, the third functional part is hinged to the end of the second handle away from the second functional part; when the locking structure is installed at the end of the second handle, the third functional part is hinged to the end of the first handle away from the first functional part.
[0008] Furthermore, the locking structure includes an elastic element connected to the first handle or the second handle. In the retracted state, the elastic element abuts against and limits the end of the first handle or the second handle. Preferably, the elastic element can be a spring sheet. The elasticity of the spring sheet facilitates abutment or locking with the first handle or the second handle during locking. During locking, a clamping force is applied to the end face of the first handle or the second handle, increasing the damping effect when the first handle or the second handle is rotated open, making it difficult to open when the handle is closed. The elasticity of the spring sheet also allows for compression during unlocking, thus avoiding contact with the first handle or the second handle during unlocking. This design also facilitates avoidance of contact with the first handle or the second handle during unlocking, an advantage not found in locking structures without elasticity.
[0009] Furthermore, the shape of the elastic element is adapted to the shape of the tail end of the first handle, the tail end of the second handle, or the tail end of the third functional part. This arrangement facilitates the elastic element's engagement with the first or second handle, thereby increasing the reliability of the locking structure's locking function.
[0010] Furthermore, both the elastic element and the tail end of the first handle or the tail end of the second handle are arc-shaped structures. Setting the tail ends of the first and / or second handles to arc-shaped structures facilitates relative rotation of the first functional part relative to the first handle and the second functional part relative to the second handle, thereby facilitating the unfolding and folding of the first and second functional parts and allowing for flexible switching between the tool's use and storage states. Furthermore, when the elastic element abuts or engages with the third functional part to achieve a limiting lock, the contact point between the third functional part and the elastic element is also set to an arc-shaped structure. Within the understanding of those skilled in the art, the tail ends of the first and / or second handles can also be configured with other shapes and structures.
[0011] Furthermore, the locking structure also includes a connector, through which the elastic element is connected to the first handle or the second handle, with a clearance between the elastic element and the connector. The connector serves as a transition between the elastic element and the first or second handle, facilitating connection between the elastic element and the first or second handle. Moreover, it ensures that the elastic element maintains an optimal angle with the first or second handle after installation, which is beneficial for engaging, locking, or unlocking the first or second handle.
[0012] Furthermore, it also includes a belt clip, which is connected to the first handle or the second handle, and the locking structure is connected to the first handle or the second handle via the belt clip. The belt clip, as an additional function, increases the portability of the tool, while placing the locking structure on the belt clip enriches the tool's functionality and increases its versatility.
[0013] Furthermore, both the first functional part and the second functional part are pliers heads. By using pliers heads to achieve the cutting function of the tool, the tool becomes pliers. On this basis, the pliers can also be made more versatile, making them multifunctional pliers.
[0014] Furthermore, both the first and second functional units are scissors. Similarly, by using scissors to achieve the cutting function of the tool, the tool becomes scissors. On this basis, the scissors can be made more multifunctional, becoming multifunctional scissors.
[0015] Furthermore, it also includes a fourth functional unit and a third handle, wherein the fourth functional unit is hinged to the third handle, and the third functional unit is hinged to the fourth functional unit. When the first functional unit and the second functional unit cooperate with each other, and the third functional unit and the fourth functional unit cooperate with each other, the first functional unit and the second functional unit can be set as scissors, and the third functional unit and the fourth functional unit can be set as pliers heads, or they can be interchanged, or other settings can be made.
[0016] Furthermore, there are two elastic elements, namely a first elastic element and a second elastic element. The first elastic element and the second elastic element are cantilevered sequentially along the connector. When the connector is connected to the first handle, the first elastic element and the second elastic element are both located on the same side of the connector, and the length of the second elastic element is greater than the length of the first elastic element. The first elastic element abuts or engages with the tail end of the fourth functional part, and the second elastic element abuts or engages with the tail end of the third functional part. When the connector is connected to the second handle, the first elastic element and the second elastic element are located on different sides of the connector. The first elastic element abuts or engages with the tail end of the third functional part, and the second elastic element abuts or engages with the tail end of the fourth functional part. By setting the first elastic element and the second elastic element, the locking structure can simultaneously engage and lock the first handle and the second handle when the tool is in the stored state, thereby increasing the locking force. The user needs to overcome greater resistance to unlock, which has the functions of preventing disengagement and preventing mis-locking.
[0017] Furthermore, there are two locking structures, one of which is connected to the first handle and the other is connected to the third handle. Each locking structure is equipped with an elastic element. By setting two locking structures, the first, second, and third handles can be simultaneously engaged or locked when the tool is in the stored state, thereby increasing the locking force. The user needs to overcome greater resistance to unlock, which has the functions of preventing slippage and preventing mis-locking.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] By incorporating a locking structure on the first and / or second handles, a locking function is achieved, preventing the handles from rotating freely relative to each other in the retracted state. This makes the handles less prone to opening when closed, reducing handle play and preventing the first or second functional part from being exposed on the surface of the first or second handle due to the handles springing open, thus eliminating safety hazards. Specifically, the locking structure abuts or engages with the first or second handle to achieve its locking function. Attached Figure Description

[0032] Example 1
[0033] like Figures 1 to 4The illustration shows an embodiment 1 of a tool with an auxiliary locking structure according to the present invention. It includes a first functional part 11 and a second functional part 21 that are hinged to each other, and a first handle 12 and a second handle 22. The first handle 12 is hinged to the first functional part 11, and the second handle 22 is hinged to the second functional part 21. The first functional part 11 and the second functional part 21 can be rotated and folded relative to the first handle 12 and the second handle 22 and stored inside the first handle 12 and the second handle 22. It also includes a locking structure 3, which is installed at the end of the first handle 12 and can abut or lock with the end of the second handle 22, and / or the locking structure 3 is installed at the end of the second handle 22 and can abut or lock with the end of the first handle 12.
[0034] This utility model uses a first functional part 11 and a second functional part 21 hinged together. The opening and closing of the first and second functional parts 21 achieves the corresponding functions. The first functional part 11 and the second functional part 21 can be pliers heads or scissor blades, thus realizing the function of pliers or scissors. A first handle 12 is hinged to the first functional part 11, and a second handle 22 is hinged to the second functional part 21. By gripping and applying force to the handles, the first and second functional parts 21 can be opened and closed. Furthermore, the first functional part 11 and the second functional part 21 can rotate and fold relative to the first handle 12 and the second handle 22, so that when not in use, the first functional part 11 and the second functional part 21 can be stored inside the first handle 12 and the second handle 22, and unfolded when in use. The locking structure 3 is installed at the tail end of the first handle 12 or the second handle 22. In the retracted state, it provides a pre-tightening force between the first handle 12 and the second handle 22, locking the handles and preventing them from easily opening when closed. This reduces handle play and prevents the first functional part 11 or the second functional part 21 from protruding from the surface of the first handle 12 or the second handle 22, eliminating safety hazards. Specifically, the locking structure 3 abuts against the tail end of the first handle 12 and / or the tail end of the second handle 22. The locking structure 3 is positioned such that it interlocks with the tail end of the first handle 12 or the tail end of the second handle 22, or a limiting structure is provided at the bottom of the locking structure 3 to lock and limit its engagement with the first handle 12 or the second handle 22, thus achieving its locking function.
[0035] As an improvement to this embodiment, both the first functional part 11 and the second functional part 21 are scissors. In this embodiment, the tool with the auxiliary locking structure of this utility model is a pair of scissors. When the scissors are in a non-use, stored state, the locking structure 3 can be used to lock the handle, preventing the handle and scissors from rotating freely and causing the handle to pop open and the scissors to protrude from the handle surface. This eliminates safety hazards and also facilitates the storage of the scissors.
[0036] Specifically, the locking structure 3 is an elastic element 31, which is connected to the first handle 12 or the second handle 22. In the retracted state, the elastic element 31 abuts or engages with the tail end of the first handle 12 or the tail end of the second handle 22 for limiting its position. Preferably, the elastic element 31 can be a spring sheet, which utilizes its elasticity to facilitate interference abutment or engagement with the first handle 12 or the second handle 22 for limiting its position when locked. When locked, it provides a clamping force on the end face of the first handle 12 or the second handle 22, increasing the damping effect of the first handle 12 or the second handle 22 when rotating open, making it difficult for the handle to open when closed; it also facilitates avoidance of the first handle 12 or the second handle 22 when unlocking. In this embodiment, the locking structure 3 is disposed on the first handle 12, and the elastic element 31 abuts or engages with the tail end of the second handle 22 for limiting its position when retracted, thereby preventing the entire pliers from opening accidentally.
[0037] Furthermore, the shape of the elastic element 31 is adapted to the shape of the tail end of the first handle 12 or the tail end of the second handle 22. In this embodiment, the locking structure 3 is disposed on the first handle 12, so the shape of the elastic element 31 is adapted to the shape of the tail end of the second handle 22.
[0038] Example 2
[0039] like Figure 5 and Figure 6 The illustration shows Embodiment 2 of a tool with an auxiliary locking structure according to the present invention. This embodiment is similar to Embodiment 1, except that the locking structure 3 further includes a connecting member 32. The elastic member 31 is connected to the first handle 12 or the second handle 22 through the connecting member 32, and a clearance is provided between the elastic member 31 and the connecting member 32. The connecting member 32 serves as a transition between the elastic member 31 and the first handle 12 or the second handle 22, facilitating the connection between the elastic member 31 and the first handle 12 or the second handle 22. Moreover, it allows the elastic member 31 to maintain an optimal angle with the first handle 12 or the second handle 22 after installation, which is beneficial for engaging, locking, or unlocking the first handle 12 or the second handle 22.
[0040] As an improvement to this embodiment, a belt clip 4 is also included. The belt clip 4 is connected to the first handle 12 or the second handle 22, and the locking structure 3 is connected to the first handle 12 or the second handle 22 through the belt clip 4. In this embodiment, the locking structure 3 is disposed on the first handle 12. Therefore, the belt clip 4 is also disposed on the first handle 12. The belt clip 4 serves as an additional function, which can increase the portability of the tool. Furthermore, disposing of the locking structure 3 on the belt clip 4 can enrich the functionality of the tool and increase its versatility.
[0041] Example 3
[0042] like Figure 8The illustration shows Embodiment 3 of a tool with an auxiliary locking structure according to the present invention. This embodiment is similar to Embodiment 2, except that it further includes a fourth functional part 52 and a third handle 53. The fourth functional part 52 and the third handle 53 are hinged together, and the third functional part 51 and the fourth functional part 52 are also hinged together. When the first functional part 11 and the second functional part 21 cooperate with each other, and the third functional part 51 and the fourth functional part 52 cooperate with each other, the first functional part 11 and the second functional part 21 can be configured as scissors, and the third functional part 51 and the fourth functional part 52 can be configured as pliers, or they can be interchanged, or other configurations can be used.
[0043] As an improvement to this embodiment, such as Figure 7 As shown, the first elastic element 311 and the second elastic element 312 are cantilevered along the connector 32. When the connector 32 is connected to the first handle 12, the first elastic element 311 and the second elastic element 312 are both located on the same side of the connector 32, and the length of the second elastic element 312 is greater than the length of the first elastic element 311. The first elastic element 311 abuts or engages with the tail end of the fourth functional part 52, and the second elastic element 312 abuts or engages with the tail end of the third functional part 51. When the connector 32 is connected to the second handle 22, the first elastic element 311 and the second elastic element 312 are located on different sides of the connector 32. The first elastic element 311 abuts or engages with the tail end of the third functional part 51, and the second elastic element 312 abuts or engages with the tail end of the fourth functional part 52. By setting the first elastic element 311 and the second elastic element 312, the locking structure 3 can simultaneously abut or lock the first handle 12 and the second handle 22 when the tool is in the stored state, thereby increasing the locking force. The user needs to overcome greater resistance to unlock, which has the functions of preventing slippage and preventing mis-locking.
[0044] In this embodiment, only one locking structure 3 is provided, only one connecting member 32 is provided, and two elastic members 31 are provided. The first elastic member 311 and the second elastic member 312 are provided in different positions and with different lengths. Specifically, the first elastic member 311 and the second elastic member 312 can be provided on the same side of the connecting member 32, and the length of the second elastic member 312 is greater than the length of the first elastic member 311. The first elastic member 311 and the second elastic member 312 are connected to the first handle 12 through the connecting member 32. The first elastic member 311 and the second elastic member 312 are provided with cantilevered so that the first elastic member 311 abuts or engages with the fourth functional part 52 or the second handle 22, while the second elastic member 312 abuts or engages with the third functional part 51 or the third handle 53, thereby achieving locking between the first handle 12, the second handle 22, and the third handle 53. Similarly, the first elastic element 311 and the second elastic element 312 can be disposed on different sides of the connector 32, that is, the first elastic element 311 and the second elastic element 312 are respectively disposed on the upper and lower sides of the connector 32. The connector 32 is disposed on the second handle 22. The first elastic element 311 and the second elastic element 312 are cantilevered so that the first elastic element 311 abuts or engages with the first handle 12, while the second elastic element 312 abuts or engages with the third handle 53 or the third functional part 51, thereby achieving locking between the first handle 12, the second handle 22 and the third handle 53.
[0045] Preferably, the elastic element 31, the tail ends of the third functional part 51, and the tail ends of the fourth functional part 52 are all arc-shaped structures. This arrangement facilitates the engagement of the elastic element 31 with the third functional part 51 and the fourth functional part 52, thereby increasing the reliability of the locking function of the locking structure 3. Setting the tail ends of the third functional part 51 and / or the fourth functional part 52 as arc-shaped structures facilitates the relative rotation of the third functional part 51 relative to the second handle 22 and the relative rotation of the fourth functional part 52 relative to the third handle 53, thereby facilitating the unfolding and folding of the third and fourth functional parts 51 and allowing for flexible switching between the tool's use and storage states. Within the understanding of those skilled in the art, the tail ends of the first handle and / or the second handle can also be configured with other shapes, such as planar structures.
[0046] Example 4
[0047] The following is Embodiment 4 of a tool with an auxiliary locking structure according to the present invention. This embodiment is similar to Embodiment 3, except that there are two locking structures 3. One locking structure 3 is connected to the first handle 12, and the other locking structure 3 is connected to the third handle 53. The locking structure 3 includes a connector 32 and an elastic member 31. By providing a locking structure 3 on both the first handle 12 and the third handle 53, the elastic members 31 on the two locking structures 3 can abut or engage with the fourth functional part 52 or the second handle 22, and the third functional part 51 or the third handle 53 respectively in the closed state, thereby achieving locking between the first handle 12, the second handle 22, and the third handle 53.
[0048] Example 5
[0049] The following is Embodiment 5 of a tool with an auxiliary locking structure according to the present invention. This embodiment is similar to Embodiment 1, except that both the first functional part 11 and the second functional part 21 are pliers. In this embodiment, the tool with the auxiliary locking structure of the present invention is a pair of pliers. When the pliers are in a non-use, stored state, the locking structure 3 can be used to lock the handle, preventing the handle and pliers head from rotating freely and causing the handle to spring open and the pliers head to protrude from the handle surface. This eliminates safety hazards and also facilitates the storage of the pliers.
