Description

Technical Field

[0001] This invention relates to a type of rescue tool pliers, and more particularly to a type of ring-breaking rescue pliers that can safely free fingers that are bound by rings using only one tool. Background Technology

[0002] Ring cutting is a common social assistance incident encountered by fire and rescue teams in their work. Statistics on such incidents have shown an upward trend in recent years. Those trapped in these situations are primarily suffering from swelling and congestion in their finger joints due to injuries, excessive exercise, handling, lifting, or improper exertion in daily life and work.

[0003] Currently, due to the various materials used in ring rescues, a wide variety of tools are typically employed, leading to complex rescue procedures. Commonly used tools include: extra-large power cutters, top cutters, diagonal pliers, needle-nose pliers, snap ring pliers, angle grinders, electric grout cleaners, electric hand grinders, and even toothed saws. However, in practice, these tools are difficult to control, easily resulting in finger injuries such as pinching, cuts, and burns. Furthermore, there is a risk of secondary injury to young children who may be trapped, as their cooperation is often low. Rescue time typically exceeds 10 minutes, increasing the risk of infection.

[0004] Currently, our team uses at least one pair of flat-nose pliers and two top-cutting pliers to successfully rescue the ring. However, this method still has drawbacks such as having too many tools and a complicated rescue procedure. For example, we first use flat-nose pliers to clamp the ring until it is deformed and protrudes, then use top-cutting pliers to cut the ring off. Finally, we use two top-cutting pliers to clamp the broken edge of the ring and pull it in opposite directions to widen the broken edge, thus successfully rescuing the ring.

[0005] However, the above-mentioned rescue tools are not dedicated tools for breaking the rules and rescuing people, but rather are a last resort based on the actual situation of the rescue. Therefore, a dedicated rescue tool, pliers, needs to be developed to address the current situation of breaking the rules and rescuing people. Summary of the Invention

[0006] In view of the existing technical problems such as the complexity and variety of rescue tools, the cumbersome rescue procedures, and the need to use multiple pliers in combination, there is no dedicated rescue tool pliers for breaking and rescuing. This invention provides a rescue pliers for breaking and rescuing that can be carried out quickly, efficiently, and safely with only one pair of pliers.

[0007] The technical solution adopted by this invention to solve the problems of the prior art is as follows:

[0008] A ring-breaking rescue pliers includes a plier head and a plier handle that cooperates with the plier head for opening and closing; the plier head includes a toothed portion and a pivot portion connecting the toothed portion; an empty hole is provided between the toothed portion and the pivot portion; the empty hole is provided along the length direction of the plier handle and simultaneously penetrates the toothed portion and the pivot portion along the height direction of the plier handle; a clamping portion for ring deformation is provided at the end of the plier handle near the plier head; the plier handle is fixedly connected to the corresponding pivot portion.

[0009] This technical solution features a pliers head with a teeth section and a pivot section, connected by a through hole. This design offers several advantages: firstly, it facilitates cutting the ring and allows for better selection of the cutting point; secondly, it saves effort by preventing the ring's sides from blocking other parts of the pliers head, reducing ineffective force; and thirdly, it allows the teeth of the pliers head to be placed stably on both sides of the ring's cut, eliminating the need for forceful clamping and reducing the suffering of the trapped person. A separate clamping section is provided on the pliers handle to facilitate gripping and deforming the ring. Quickly identifying the protruding cutting point after the ring deforms is a prerequisite for efficient rescue. This solution utilizes the opening and closing space of the pliers handle on the side closest to the pliers head to create this clamping section, saving time and effort, allowing for a single clamping action to break the ring and rescue it.

[0010] Preferably, the biting part is provided with corresponding cutting teeth that can cut the ring, and the top of each cutting tooth is provided with a guide tooth that can pass through the protrusion after the ring is deformed; when the two cutting teeth are closed, the bottom surface of the guide tooth part fits against the top of the other cutting tooth. Because the fingers of the trapped person are congested and swollen, the ring is usually embedded in the finger, that is, the skin of the finger is higher than the surface of the ring. In order to avoid secondary damage when the biting part breaks and cuts the skin of the trapped person again, the guide tooth is first inserted into the protrusion before cutting. This completely avoids secondary damage and further reduces the fear and pain of the trapped person.

[0011] Preferably, the pivoting part includes a first pivot block, which has a through hole in its height direction and along its width direction; a second pivot block passes through the through hole and is pivotally connected to the first pivot block by a pin. The premise of breaking and rescuing rings is stability, efficiency, and safety; this design greatly improves the stability of the pliers when applying cutting force; especially after multiple cuts, the advantage is more prominent when using the same pliers again, because most people wear alloy rings, and the hard material of alloy rings can easily damage the pliers during the breaking and rescue process, shortening the service life of the pliers.

[0012] As a preferred structure of the clamping part, the clamping part includes a first pressing protrusion disposed opposite to each other on the inner side of the pliers handle on the side away from the pliers head; and a second pressing protrusion disposed opposite to each other on the inner side of the pliers handle on the side closer to the pliers head; the first pressing protrusion and the second pressing protrusion together enclose a ring clamping opening. Further, the inner diameter of the ring clamping opening on the side away from the pliers head is larger than the inner diameter on the side closer to the pliers head. This arrangement allows for the directional generation of the ring protrusion point, enabling the quick location of the cutting point based on the actual situation on site; or the selection of the correct position for using the pliers.

[0013] To further widen the gap between the broken ends of the ring without requiring secondary or even multiple cuts, the front end face of the toothed part is equipped with a lever capable of separating the broken ends. Furthermore, the lever is a slender, conical shape. Furthermore, the tip of the lever has an arc-shaped portion. Furthermore, the tip of the lever has an anti-slip sleeve. Based on the actual situation, when multiple cuts are not required, this technical solution can efficiently separate the broken ends of the ring, thus quickly freeing the finger. The arc-shaped portion or anti-slip sleeve on the lever provides an anti-slip effect when separating the broken ends, resulting in a smooth, efficient, and safe rescue.

[0014] Preferably, the pliers handle is provided with an anti-slip sleeve. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1The ring-breaking rescue pliers shown are based on the same principle as existing technology. They include a plier head 1 and a plier handle 2 that cooperates with the plier head 1 to open and close it. The manual plier handle 2 then opens / closes the plier head 1 to complete the task. The difference is that the plier head 1 is configured as a toothed part 11 and a pivot part 12 connecting the toothed part 11; a through hole 13 is provided between the toothed part 11 and the pivot part 12 along the length and height of the plier handle 2; a clamping part 21 for ring deformation is provided on the section of the plier handle 2 near the plier head 1; the plier handle 2 is fixedly connected to the corresponding pivot part 12.

[0023] The advantages of the through-hole 13 in this invention are as follows: firstly, it facilitates cutting the ring and allows for better selection of the cutting point; secondly, it saves effort by preventing the side of the ring, made of high-hardness material, from blocking other parts of the clamp head 1, thus reducing ineffective force; and thirdly, it allows the teeth 11 of the clamp head 1 to be placed completely and stably on both sides of the ring cut, without the need to forcefully clamp it onto the ring, reducing the pain for those trapped later. As a preferred structure of the teeth 11: the teeth 11 are provided with corresponding cutting teeth 111 capable of cutting the ring, and the top of each cutting tooth 111 is provided with a guide tooth 112 that can pass through the ring after deformation; when the two cutting teeth 111 are closed, the bottom surface of the guide tooth 112 is in contact with the top of the other cutting tooth 111. Because the fingers of the trapped person are congested and swollen, the ring is usually embedded in the finger, meaning the skin of the finger is higher than the surface of the ring. In order to avoid secondary damage when the clamping part 21 causes the ring to deform and create a protruding point, the guide tooth 112 is inserted into the protruding point first before cutting, so as to completely avoid secondary damage and further reduce the pain of the trapped person.

[0024] This invention provides a separate clamping part 21 on the pliers handle 2 to facilitate clamping and removing deformed rings. Quickly identifying the protruding shear point after ring deformation is a prerequisite for efficient and successful rescue. This solution utilizes the opening and closing space of the pliers handle 2 on the side near the pliers head 1 to provide the clamping part 21, saving time and effort, and allowing for ring removal with a single clamp. As a preferred structure of the clamping part 21, it includes a first pressing protrusion 211 located opposite to each other on the inner side of the pliers handle 2 on the side away from the pliers head 1; and a second pressing protrusion 212 located opposite to each other on the inner side of the pliers handle 2 on the side near the pliers head 1; the first pressing protrusion 211 and the second pressing protrusion 212 together form a ring clamping opening 213. Furthermore, the inner diameter of the ring clamping opening 213 on the side away from the pliers head 1 is larger than the inner diameter on the side near the pliers head 1. This arrangement can orient the ring to the protruding point, allowing for quick location of the shear point based on the actual situation; or selection of the correct position for using the pliers.

[0025] In existing technologies, the pivot section 12 is generally stacked. In this invention, as a preferred structure of the pivot section 12, the pivot section 12 includes a first pivot block 121. The first pivot block 121 has a through hole 123 in its height direction and along its width direction. A second pivot block 122 passes through the through hole 123 and is pivotally connected to the first pivot block 121 via a pin 124. The premise of breaking and rescuing rings is stability, efficiency, and safety. This design greatly improves the stability of the pliers when applying cutting force. This advantage is particularly pronounced when using the same pliers again after multiple cuts, as most people wear alloy rings. The hardness of alloy rings makes the pliers prone to damage during the breaking and rescue process, shortening their lifespan.

[0026] To better achieve the goal of rescuing the finger with a single clamp and further widen the gap between the broken ends of the ring, eliminating the need for secondary or even multiple cuts, the front end of the cleaving part 11 is equipped with a lever 3 that can separate the broken ends of the ring. A preferred design for the lever 3 is its slender, conical shape; the tip of the lever 3 can have an arc-shaped portion 31 or be replaced with an anti-slip sleeve. Thus, depending on the actual situation, when no secondary or multiple cuts are required, this technical solution can efficiently separate the broken ends of the ring, thereby quickly rescuing the finger. The arc-shaped portion 31 or the anti-slip sleeve on the lever 3 improves the anti-slip effect, achieving a smooth, efficient, and safe rescue. Similarly, an anti-slip sleeve can also be provided on the clamp handle 2.
