Description

Technical Field

[0001] This invention relates to a tool, and more particularly to a pliers or shearing tool. Background Technology

[0002] Existing conventional pliers and shears consist of two tool arms hinged together by a pin. Each arm has a cutting section on one side of the hinge point (head side), and a handle on the other side (tail side). The cutting sections can have various shapes of cutting edges or jaws with clamping or twisting functions. When using these tools, the user opens and closes the cutting sections by rotating the handle, thus achieving various functions such as cutting and clamping. The conventional way to use these tools relies on the operator's hand strength to press the handle, making them a handheld tool. However, the cutting force exerted by the hand is limited, making them unsuitable for high-load cutting scenarios requiring greater force. This results in poor scenario applicability and is particularly prone to causing hand fatigue. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a pliers or shears tool that is simple in structure, easy to use, and suitable not only for handheld work with low load, but also for labor-saving work with high load.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a pliers / scissors tool, comprising two tool arms hinged together, with a cutting part corresponding to one side of the hinge point and a handle part corresponding to the other side of the hinge point. At least one of the handle parts includes a front half of the handle near the hinge point and a rear half of the handle away from the hinge point. The rear half of the handle includes a first opening / closing handle and a second opening / closing handle. The first opening / closing handle and the second opening / closing handle are correspondingly connected to the front half of the handle and are in an unfolded state and a closed state. When the rear half of the handle is in the unfolded state, the outer surfaces of the first opening / closing handle and the second opening / closing handle cooperate to form a stable support plane in the shape of a virtual triangle.

[0005] As a preferred technical solution, when the rear half of the handle is in the unfolded state, the outer surfaces of the first and second opening and closing handles cooperate to form a stable support plane in the shape of a virtual triangle; when the rear half of the handle is in the closed state, the first and second opening and closing handles and the front half of the handle together form a rod-type handle structure.

[0006] As a preferred technical solution, the outer surface of the first opening and closing handle is provided with a first support portion, and the outer surface of the second opening and closing handle is provided with a second support portion. When the rear half of the handle is in the unfolded state, the first support portion and the second support portion cooperate to form the stable support plane.

[0007] As a preferred technical solution, when the rear half of the handle of one of the handle portions is in the unfolded state, the horizontal unfolding surface between the first opening and closing handle and the second opening and closing handle is perpendicular to the movable shearing surface of the other handle portion.

[0008] As a preferred technical solution, the outer surface of the front half of the handle is provided with a front support portion that is located on the same plane as the stable support plane.

[0009] As a preferred technical solution, an opening and closing rotation structure is provided between the first opening and closing handle, the second opening and closing handle, and the front half of the handle.

[0010] As a preferred technical solution, the opening and closing rotation structure includes a pin installed on the front half of the handle, and the first opening and closing handle and the second opening and closing handle are provided with opening and closing rotation holes that correspond to and rotate with the pin.

[0011] As a preferred technical solution, an opening and closing control component is further provided between the first opening and closing handle and the second opening and closing handle. The opening and closing control component is located on the front half of the handle and controls the rear half of the handle to switch between an unfolded state and a closed state.

[0012] As a preferred technical solution, the opening and closing control component includes an opening and closing limiting slide rail disposed on the rear half of the handle, an opening and closing limiting slider slidably mounted on the opening and closing limiting slide rail, a slider receiving cavity for accommodating the opening and closing limiting slider is provided between the first opening and closing sub-handle and the second opening and closing handle, and a locking structure is provided between the opening and closing limiting slider and the first opening and closing handle and the second opening and closing handle.

[0013] As a preferred technical solution, the locking structure includes an unfolding limiting lock block and a merging limiting lock block disposed on the opening and closing limiting slider. The unfolding limiting lock block and the merging limiting lock block are located at opposite ends of the sliding direction of the opening and closing limiting slide. The first opening and closing handle has a first unfolding limiting lock groove corresponding to the unfolding limiting lock block at one end of the slider receiving cavity, and a first merging limiting lock groove corresponding to the merging limiting lock block at the other end of the first opening and closing handle. The second opening and closing handle has a second unfolding limiting lock groove corresponding to the unfolding limiting lock block at one end of the slider receiving cavity, and a second merging limiting lock groove corresponding to the merging limiting lock block at the other end of the second opening and closing handle.

[0014] As a preferred technical solution, the opening and closing control component further includes a magnetic attraction structure disposed between the first opening and closing handle and the second opening and closing component.

[0015] Due to the adoption of the above technical solution, a pliers / scissors tool includes two hinged arms. Each arm has a cutting section on one side of the hinge point, and a handle on the other side. At least one handle includes a front half near the hinge point and a rear half away from the hinge point. The rear half includes a first opening / closing handle and a second opening / closing handle. The first and second opening / closing handles are correspondingly connected to the front half of the handle and can be in an unfolded state and a closed state. When the handle is in a closed state... When the half is in the unfolded state, the outer surfaces of the first and second opening handles cooperate to form a stable support plane in the shape of a virtual triangle. The beneficial effects of this invention are: this invention designs a pliers-like tool that can be used in both tabletop and handheld modes, realizing the conversion between tabletop and handheld modes, so as to adapt to both low-load (requiring less force, handheld) and high-load (requiring more force, tabletop) cutting scenarios, thereby improving the applicability of the scenario; this invention also has the advantages of simple structure, convenient use, and easy operation, and has good promotional value.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, a pair of pliers includes two hinged arms. Each of the two arms has a cutting section 100 on one side of the hinge point and a handle section 200 on the other side of the hinge point. In this embodiment, one of the handle sections 200 adopts a conventional pliers handle, which can be a rod-shaped or arc-shaped handle. The other handle section 200 adopts a split handle that can be unfolded and merged.

[0033] like Figures 1 to 4 As shown, the split handle includes a front half 201 of the handle near the hinge point and a rear half of the handle away from the hinge point. The rear half of the handle includes a first opening and closing handle 202 and a second opening and closing handle 203. The first opening and closing handle 202 and the second opening and closing handle 203 are correspondingly connected to the front half 201 of the handle and the two cooperate to have an unfolded state and a closed state.

[0034] When the rear half of the handle is in the unfolded state, it splits into two parts: the first hinged handle 202 and the second hinged handle 203. The outer surfaces of the first hinged handle 202 and the second hinged handle 203 cooperate to form a stable support plane in the shape of a virtual triangle. This virtual stable support plane can be supported on the same plane (tabletop / ground), achieving a stable support effect. This allows for the conversion from handheld to tabletop type. Workers can use their body weight or other methods to handle high loads using the transformed tabletop pliers and shears. This tool is suitable for cutting / clamping items that require significant force, saving manpower. When the rear half of the handle is in the closed state, the first opening and closing handle 202, the second opening and closing handle 203, and the front half of the handle 201 together form a lever-type handle structure. This lever-type handle structure is similar to the conventional pliers and shears handle structure in the prior art. The two handle parts 200 cooperate to form a handheld handle, making the overall pliers and shears tool no different from the conventional pliers and shears tool. It is easy to hold and can be used for cutting work with low load (requiring less force).

[0035] See Figure 1 , Figure 2 and Figure 6 The outer surface of the first hinged handle 202 is provided with a first support portion 204, and the outer surface of the second hinged handle 203 is provided with a second support portion 205. When the rear half of the handle is in the unfolded state, the first support portion 204 and the second support portion 205 cooperate to form the stable support plane. In this embodiment, when the first hinged handle 202 and the second hinged handle 203 are separated, they are two separate rod-like structures. When the first hinged handle 202 and the second hinged handle 203 are combined, they are correspondingly inserted and fastened to form a complete rod-like handle structure, similar to conventional handles in the prior art.

[0036] In this embodiment, the first support portion 204 includes two support surfaces located at the front and rear ends of the outer surface of the first hinge handle 202, and the second support portion 205 includes a support surface located on the outer surface of the second hinge handle 203. All support surfaces are located on the same surface. When in the unfolded state, although all support surfaces are discontinuously distributed, they can cooperate to form a stable support plane in the shape of a virtual triangle because they are located on the same surface. Although the triangle is not a perfect triangle, it is similar to three-point or three-line support, providing a stable support effect. Of course, the first support portion 204 and the second support portion 205 may not be support surfaces, but may be support lines or support points. However, the support effect is best when using support surfaces.

[0037] See Figure 2 When the rear half of the split handle is in the unfolded state, the horizontal unfolding surface between the first opening / closing handle 202 and the second opening / closing handle 203 is perpendicular to the movable shearing surface of the other handle portion 200. This ensures that when the first opening / closing handle 202 and the second opening / closing handle 203 are supported on a flat surface in a table-like manner, pressing the other handle portion 200 towards the split handle will achieve a shearing effect, and the shearing direction is basically consistent with the movement direction when pressing the handle. To ensure better support, the first opening / closing handle 202 and the second opening / closing handle 203 open to both sides, and the angles of opening to both sides are symmetrical about the other handle portion 200.

[0038] See Figures 5 to 10An opening and closing rotation structure is provided between the first opening and closing handle 202, the second opening and closing handle 203, and the front half of the handle 201. The opening and closing rotation structure includes a pin 206 mounted on the front half of the handle 201. The pin 206 is a pin, and the tail end of the front half of the handle 201 has a threaded hole. The end of the pin is threadedly connected to the tail end of the front half of the handle 201. The top ends of the first opening and closing handle 202 and the second opening and closing handle 203 have opening and closing rotation holes 207 that rotatably engage with the pin 206. The two opening and closing rotation holes 207 are respectively fitted onto the surface axis of the pin and are limited by the pin, realizing a hinged connection between the first opening and closing handle 202 and the second opening and closing handle 203. The first opening and closing handle 202 and the second opening and closing handle 203 can rotate around the pin 206 to achieve opening and closing.

[0039] To limit the opening and closing states and prevent the tool from opening and closing arbitrarily during use, an opening and closing control component is provided. An opening and closing control component is also provided between the first opening and closing handle 202 and the second opening and closing handle 203. This component is located on the front half 201 of the handle and controls the switching of the rear half of the handle between the opening and closing states. The opening and closing control component includes an opening and closing limiting slide 208 located on the rear half of the handle. The opening and closing limiting slide 208 is arranged along the length of the rear half of the handle. An opening and closing limiting slider 209 is slidably mounted on the opening and closing limiting slide 208. The opening and closing limiting slider 209 is provided with a sliding guide post 210 that can pass through the opening and closing limiting slide 208. The sliding guide post 210 extends out of the inner side of the rear half of the handle and is provided with an operating button 211 that is convenient for the operator's finger to operate. The opening and closing limiting slider 209 achieves limited sliding along the opening and closing limiting slide 208 through the operating button 211 and the sliding guide post 210. A slider receiving cavity is provided between the first opening and closing sub-handle 202 and the second opening and closing handle 203 to accommodate the opening and closing limiting slider 209. A locking structure is provided between the opening and closing limiting slider 209 and the first opening and closing handle 202 and the second opening and closing handle 203.

[0040] See Figures 5 to 10The locking structure includes an unfolding limiting lock block 212 and a merging limiting lock block 213 disposed on the opening and closing limiting slider 209. The unfolding limiting lock block 212 and the merging limiting lock block 213 are located at opposite ends of the opening and closing limiting slide 208 in the sliding direction. The first opening and closing handle 202 has a first unfolding limiting lock groove 214 corresponding to the unfolding limiting lock block 212 at one end of the slider receiving cavity, and a first merging limiting lock groove 215 corresponding to the merging limiting lock block 213 at the other end of the first opening and closing handle 202 in the slider receiving cavity. The second opening and closing handle 203 has a first merging limiting lock groove 215 corresponding to the merging limiting lock block 213 at the other end of the slider receiving cavity. One end of the slider receiving cavity is provided with a second unfolding limiting lock groove 216 corresponding to the unfolding limiting lock block 212, and the other end of the second opening and closing handle 203 located in the slider receiving cavity is provided with a second merging limiting lock groove 217 corresponding to the merging limiting lock block 213; when the opening and closing limiting slider 209 slides along the opening and closing limiting slide 208 to the unfolded position at the front end, the unfolding limiting lock block 212 simultaneously engages with the first unfolding limiting lock groove 214 and the second unfolding limiting lock groove 216, locking the positions of the first opening and closing handle 202 and the second opening and closing handle 203 in this unfolded state. See [reference needed] Figure 10 When the opening / closing limiting slider 209 slides along the opening / closing limiting slide rail 208 to the merging position at the rear end, the merging limiting lock block 213 simultaneously engages with the first merging limiting lock groove 215 and the second merging limiting lock groove 217, locking the positions of the first opening / closing handle 202 and the second opening / closing handle 203 in this merging state. (See [link]) Figure 9 The locking block and the locking groove are connected to lock the first opening and closing handle 202 and the second opening and closing handle 203 in their open and closed states, without affecting the stability of the device in both states.

[0041] In this embodiment, the slider receiving cavity includes a first inclined guide surface 218 disposed on the first opening / closing handle 202 and a second inclined guide surface 219 disposed on the second opening / closing handle 203. The first inclined guide surface 218 and the second inclined guide surface 219 cooperate to form a conical structure that is smaller at the front and larger at the back. When the opening / closing limiting slider 209 slides forward from the closed state at the rear end to the unfolded state, it is only necessary to slide the opening / closing limiting slider 209 forward. The opening / closing limiting slider 209 will push open the first inclined guide surface 218 and the second inclined guide surface 219 to both sides. When the second inclined guide surface 219 slides to the unfolded position at the front end, the unfolding limiting lock block 212 simultaneously engages with the first unfolding limiting lock groove 214 and the second unfolding limiting lock groove 216. When it is necessary to switch to the merged state, the opening and closing limiting slider 209 is slid backward, and the hand merges the first opening and closing handle 202 and the second opening and closing handle 203. Finally, the merging limiting lock block 213 simultaneously engages with the first merging limiting lock groove 215 and the second merging limiting lock groove 217.

[0042] The opening and closing control component also includes a magnetic attraction structure disposed between the first opening and closing handle 202 and the second opening and closing handle 203. The first opening and closing handle 202 contains a first magnetic block, and the second opening and closing handle 203 contains a second magnetic block. The first magnetic block and the second magnetic block are attracted to each other, merging the first opening and closing handle 202 and the second opening and closing handle 203. When it is necessary to switch to the open state, the opening and closing limiting slider 209 is pushed to slide along the opening and closing limiting slide 208, overcoming the magnetic force to open the first opening and closing handle 202 and the second opening and closing handle 203, thus achieving the opening purpose. Of course, other snap-fit ​​methods can also be used between the first opening and closing handle 202 and the second opening and closing handle 203 for opening and closing, such as adding a separate pin for limiting.

[0043] To improve grip and anti-slip effect, a rubber layer is added to the support surface of the first opening and closing handle 202 and the second opening and closing handle 203 to achieve anti-slip effect for hand grip and anti-slip effect for table support.

[0044] The working principle of this embodiment is as follows:

[0045] When performing tasks such as cutting / clamping on high-load (requiring considerable force) items, pushing the opening / closing control component forward will cause the first opening / closing handle 202 and the second opening / closing handle 203 to rotate and open to both sides until the unfolding limiting lock block 212 on the opening / closing control component simultaneously engages with the first unfolding limiting lock groove 214 and the second unfolding limiting lock groove 216, thus maintaining the first opening / closing handle 202 and the second opening / closing handle 203 in this unfolded state. (See attached diagram for the state description.) Figure 1 At this time, the first opening / closing handle 202 and the second opening / closing handle 203 form a shape like... Figure 1 The plane of the virtual triangle formed by points A, B, and C is defined as the stable support plane. When this stable plane is supported on a surface such as a table or the ground, it can achieve [the desired effect]. Figure 12 As shown, this tool is a benchtop pliers / shear tool. The operator can use their body weight to press down on the upper handle from the top to provide greater shearing force. This saves manpower while improving shearing force. At the same time, because the bottom of the tool has a relatively stable support plane, the tool will not tip over or tilt when working in this unfolded state, resulting in good stability and safety.

[0046] When the opening and closing control component is pushed in the opposite direction, the first opening and closing handle 202 and the second opening and closing handle 203 are merged. The merging limiting lock block 213 simultaneously engages with the first merging limiting lock groove 215 and the second merging limiting lock groove 217, locking the positions of the first opening and closing handle 202 and the second opening and closing handle 203 in this merged state. (See the attached diagram for the state description.) Figure 3 At this point, the pliers and shears are no different from pliers and shears in their normal state. They are easy to hold and can be used for cutting work with lower load (requiring less force).

[0047] This invention designs a pair of pliers that can be used in both benchtop and handheld modes, enabling switching between benchtop and handheld modes to adapt to both low-load (requiring less force, handheld) and high-load (requiring more force, benchtop) cutting scenarios, thus improving its applicability.

[0048] Example 2:

[0049] The structure of this embodiment is basically the same as that of Embodiment 1, with the main difference being that both handles 200 in this embodiment adopt the split handles of Embodiment 1. When handheld use is required, both split handles are in the closed state. At this time, the overall pliers and scissors are no different from pliers and scissors in the conventional state, making them easy to hold and suitable for cutting work with lower loads (requiring less force). When tabletop use is required, one split handle is in the closed state, and the other split handle is in the open state. The handle in the open state is used to support the surface and perform cutting / clamping work on high-load (requiring greater force) items, saving manpower. The working principle at this time is basically the same as that of Embodiment 1, and will not be described again here.

[0050] Example 3:

[0051] The structure of this embodiment is basically the same as that of Embodiment 1, with the main difference being: the outer surface of the front half 201 of the handle is provided with a front support portion that is located on the same plane as the stable support plane. An additional front support portion 220 is added to the front half 201 of the handle. This front support portion 220 is located on the same plane as the stable support plane in the unfolded state, and is used to cooperate with the stable support plane to further achieve a better support effect. In particular, the front support portion 220 is fixed to the outer surface of the front half 201 of the handle, resulting in better stability. In this embodiment, the front support portion 220 can be a support surface, a support point, or a support line. Of course, using a support surface provides the best support effect. At this time, the first opening / closing handle 202, the second opening / closing handle 203, and the front half 201 of the handle form a... Figure 1 The plane of the virtual triangle formed by points A', B', and C is defined as the stable support plane. When this stable plane is supported on a surface such as a table or the ground, it can achieve [the desired effect]. Figure 12 The state shown.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
