[0038] The development of electric shock rescue poles can be traced back to the need for safe operations in the power industry. Initially, these poles were simple insulating poles used for operations or rescue operations in high-voltage environments. As power systems became more complex and safety requirements increased, the functionality of electric shock rescue poles continued to evolve.

[0039] Early electric shock rescue poles typically had only a single hooking function, primarily used to remove conductive objects from a person who has been electrocuted or to separate the person from the power source. While effective in some situations, this design proved inadequate for complex rescue scenarios. Over time, rescuers gradually realized that different electric shock situations might require different rescue tools. For example, sometimes it might be necessary to clamp an object, sometimes to cut a wire, or to retrieve certain items. However, existing electric shock rescue poles, due to their fixed head structure, were unable to meet these diverse needs.

[0040] For example, during a serious industrial accident, a worker was trapped near high-voltage equipment in a critical situation. Upon arriving at the scene, the rescue team discovered that conventional electric shock rescue poles were inadequate for effectively handling the complex situation. Rescuers needed to first cut through tangled cables, then pull the worker out by gripping his clothing, and finally retrieve tools that had fallen into the dangerous area. However, they only had a single pole with a fixed insulated hook blade, which was inadequate for these diverse tasks. This incident highlighted the limitations of existing electric shock rescue equipment. Rescuers were forced to repeatedly switch between different tools in a dangerous environment, significantly extending rescue time and increasing the risk of injury.

[0041] In this regard, please refer to the attached Figure 1 and attached Figure 2The utility model provides an electric shock rescue pole, including a head pole 100, a first end of the head pole 100 is installed with a detachable head accessory 300 through a quick-release connection structure 200, the quick-release connection structure 200 includes a slot 110 located on the first end of the head pole 100 and a plug 310 located on the head accessory 300, and the left and right sides of the slot 110 are both provided with lock holes 120 that pass through to the outside world along the left and right directions; the left and right sides of the plug 310 are both provided with locking blocks 320, and an elastic member 330 is connected between the locking block 320 and the plug 310, and the elastic member 330 is used to provide a reset elastic force for the locking block 320 so that the locking block 320 is embedded in the lock hole 120 on the same side.

[0042] The core design of this embodiment lies in the quick-release connection structure 200, which achieves a reliable and easy-to-use connection between the head rod 100 and the detachable head accessory 300. A slot 110 and a plug 310 are provided on the head rod 100 and the head accessory 300, respectively, and a preliminary connection is achieved through plug-in engagement. Locking holes 120 are provided on either side of the slot 110, corresponding to locking blocks 320 on the plug 310. The locking blocks 320 are connected to the plug 310 via an elastic member 330 and automatically engage with the locking holes 120 under the action of the elastic force, thereby achieving a secure lock.

[0043] The elastic member 330 may be, but is not limited to, a spring, an elastic washer, a rubber support, or other structures or devices capable of providing a restoring elastic force.

[0044] In specific implementation, the electric shock rescue pole of the present application includes a head pole 100 and a detachable head accessory 300. The head pole 100 is made of insulating material, with a length of 1.5 meters and a diameter of 30 mm. The first end of the head pole 100 is provided with a quick-release connection structure 200, including a slot 110 with a length of 60 mm, a width of 40 mm, and a depth of 30 mm. A circular lock hole 120 with a diameter of 5 mm is provided on each side of the slot 110, and the lock hole 120 is connected to the outside world in the left and right directions.

[0045] The head accessory 300 can be an insulated hook knife, insulated pliers, or insulated scissors, depending on the rescue needs. Taking the insulated hook knife as an example, it is equipped with a plug 310 that matches the slot 110. The plug 310 measures 55 mm long, 35 mm wide, and 25 mm high. A cylindrical locking block 320 with a diameter of 4.8 mm is located on each side of the plug 310. The locking block 320 is connected to the plug 310 via a compression spring. The spring constant of the compression spring is 20 N / mm, and the initial compression is 5 mm.

[0046] During use, the plug 310 is inserted into the slot 110. The spring-loaded locking block 320 automatically snaps into the locking hole 120, enabling quick connection. To disassemble, simply press the locking block 320 to disengage it from the locking hole 120, allowing the head accessory 300 to be easily removed. This design allows the head accessory 300 to be replaced in under 5 seconds, significantly improving rescue efficiency.

[0047] In another embodiment, the slot 110 and plug 310 can adopt a trapezoidal cross-section design to further enhance connection stability. The slot 110 has a top width of 45 mm, a bottom width of 35 mm, and a depth of 30 mm. Accordingly, the plug 310 has a top width of 44 mm, a bottom width of 34 mm, and a height of 29 mm. The locking hole 120 and locking block 320 can adopt a triangular cross-section with a side length of 5 mm. This design provides a better self-locking effect and further improves connection reliability.

[0048] This embodiment adopts this snap-on quick-release connection structure 200, which can complete assembly and disassembly faster than the threaded connection method and has good reliability and stability. By quickly replacing the head accessories 300 with different functions, one rescue pole can cope with a variety of rescue scenarios, greatly improving the efficiency and flexibility of rescue. For example, in a complex electric shock rescue, the rescuer can first use the insulated scissors accessories to cut the entangled cables, and then quickly replace them with the insulated clamp accessories to clamp the clothes of the person who was electrocuted, and finally replace them with the insulated hook knife accessories to hook the fallen tools. The whole process is smooth and efficient, which greatly improves the success rate of the rescue. It effectively solves the technical problems of the traditional rescue pole's cumbersome replacement of the head accessories 300, unstable connection and single function, and provides a safer, more efficient and multifunctional tool option for power rescue work.

[0049] In certain embodiments, reference is made to the accompanying Figure 1 and attached Figure 2 The cross-sectional shapes of the locking hole 120 and the locking block 320 along the front-to-back direction are both triangular.

[0050] By designing the cross-sections of the locking hole 120 and the locking block 320 into a triangular shape, the locking stability and reliability of the quick-release connection structure 200 can be significantly improved. The triangular cross-section design has the advantages of easier control of the installation posture of the head accessory 300, self-locking effect, deformation resistance, and precise positioning.

[0051] In some embodiments of the present application, the triangular cross-sections of the locking hole 120 and the locking block 320 can be equilateral, isosceles, or right-angled. For example, an equilateral triangle with three internal angles of 60 degrees can be used. This design can provide uniform force distribution. Another possible implementation is to use a right-angled triangle with one angle of 90 degrees, which can provide better positioning.

[0052] The triangular cross-sectional dimensions of the locking hole 120 and the locking block 320 can be adjusted based on the specific application scenario. For example, for a small electric shock rescue pole, the side length of the triangular cross-sectional dimensions can be within a range of 5-10 mm; for a large electric shock rescue pole, the side length can be within a range of 15-30 mm. This flexible dimensional design makes the technical solution of this application applicable to electric shock rescue poles of different specifications.

[0053] The triangular cross-section of the locking hole 120 and the locking block 320 work in conjunction with the other components of the quick-release connection structure 200 to enhance the stability and reliability of the entire connection structure. For example, when used in conjunction with the elastic member 330, the triangular cross-section of the locking block 320 not only provides more precise positioning but also enhances the locking force. When the locking block 320 is inserted into the locking hole 120, the interaction between the inclined surface of the triangular cross-section and the elastic force of the elastic member 330 creates a wedge effect, further enhancing the locking effect.

[0054] During use, when the head accessory 300 is installed on the head rod 100, the operator first aligns the plug 310 with the slot 110 and then inserts the plug 310 into the slot 110. The triangular cross-section design of the locking hole 120 and the locking block 320 makes it easier for the operator to grasp the correct installation posture. As the plug 310 is inserted, the locking block 320 automatically snaps into the locking hole 120 under the action of the elastic member 330. The triangular cross-section of the locking block 320 fits tightly into the locking hole 120, achieving precise positioning and a secure connection.

[0055] When the electric shock rescue pole is subjected to external forces during use, the triangular cross-section design plays an important role. First, the triangular structure itself has a strong ability to resist deformation and can withstand greater external forces without being easily deformed. Secondly, the wedge effect produced by the inclined surface of the triangular cross-section causes the locking block 320 to automatically tighten when subjected to force, further improving the reliability of the lock. This design ensures that the connection between the head accessory 300 and the head pole 100 is more secure and reliable, and is not easy to loosen or fall off even when subjected to large external forces in emergency rescue situations.

[0056] A specific embodiment is that in an electric shock rescue pole used for high-voltage line rescue, the lock hole 120 and the lock block 320 are designed with an isosceles right triangle cross-section. The length of the right-angled side of the isosceles right triangle is 15 mm, and the length of the hypotenuse is 21.2 mm. The lock hole 120 is opened on the left and right side walls of the slot 110, with a depth of 10 mm. The lock block 320 is made of high-strength engineering plastic, and its triangular cross-section is completely matched with the lock hole 120. The lock block 320 is connected to the plug 310 through a compression spring, and the elastic coefficient of the compression spring is 20 N / mm. This design not only provides precise positioning and a stable connection, but also has good insulation properties, and is suitable for use in high-voltage environments.

[0057] The triangular cross-section design of the present application not only improves positioning accuracy but also enhances structural stability. Especially in high-risk scenarios such as electric shock rescue, the design of the present application can provide a more reliable connection, significantly reducing the risk of accidental detachment of the head accessory 300, thereby improving the safety and efficiency of rescue operations. Furthermore, the triangular cross-section design simplifies the assembly process, allowing operators to install and remove the head accessory 300 more quickly and accurately, which is particularly important in emergency rescue situations.

[0058] In certain embodiments, reference is made to the accompanying Figure 1 and attached Figure 2 The plug 310 is further provided with a positioning hole 340 extending in the up-down direction; the slot 110 is provided with a positioning column 130 extending in the up-down direction, and the positioning column 130 is used to limit the head accessory 300 by being inserted into the positioning hole 340 .

[0059] In this embodiment, the positioning column 130 extends in the up and down direction and can be inserted into the positioning hole 340. This structural design can effectively limit the movement of the head accessory 300 in the front and back directions and the left and right directions, and also facilitates the rapid positioning and installation of the head accessory 300 on the head rod 100.

[0060] Specifically, the positioning hole 340 can be located at the center or near the edge of the plug 310 and can be cylindrical, square, or other polygonal in shape. The positioning post 130 is shaped to match the positioning hole 340 and can be cylindrical, square, or other polygonal in shape. The length of the positioning post 130 can be designed based on actual needs and is typically slightly shorter than the depth of the slot 110 to ensure that the plug 310 can be fully inserted into the slot 110.

[0061] The locating post 130 and the locating hole 340 can be fitted with either an interference fit or a clearance fit. An interference fit provides a better retaining effect but may increase installation difficulty; a clearance fit makes installation easier while still providing sufficient retaining effect. The appropriate fit method can be selected based on the actual application scenario.

[0062] To further enhance the positioning effect, multiple positioning holes 340 can be provided on the plug 310, and corresponding positioning posts 130 can be provided in the slot 110. For example, a positioning hole 340 can be provided at each of the four corners of the plug 310, with four positioning posts 130 provided at corresponding locations in the slot 110. This design can more comprehensively restrict the movement of the head assembly 300 and provide a more stable connection.

[0063] The design of the positioning post 130 and positioning hole 340, in conjunction with the locking block 320 and locking hole 120 in the quick-release connection structure 200, provides a multi-positioning and securing mechanism. When the head accessory 300 is inserted into the head rod 100, the positioning post 130 and positioning hole 340 provide initial positioning and securing. Then, the locking block 320, under the action of the elastic member 330, engages the locking hole 120, completing the final securement. This combined design not only improves connection stability but also simplifies the installation process.

[0064] In actual use, when installing the head accessory 300, the operator first aligns the plug 310 with the slot 110, roughly aligning the positioning post 130 with the positioning hole 340. Then, the plug 310 is gently pushed in, and the positioning post 130 is automatically guided and inserted into the positioning hole 340. During this process, the cooperation between the positioning post 130 and the positioning hole 340 serves both as a guide and as a preliminary stop. As the plug 310 continues to be inserted, the locking block 320, under the action of the elastic member 330, automatically engages the locking hole 120, completing the final fixation.

[0065] This design not only enhances the stability of the connection between the head accessory 300 and the head rod 100, but also improves the reliability and safety of the entire electric shock rescue pole. Inserting the positioning post 130 into the positioning hole 340 effectively determines the installation position of the head accessory 300 on the head rod 100, effectively improving the installation efficiency and reducing the difficulty of the head accessory 300. This design ensures that the head accessory 300 remains stable during use, preventing loosening or shifting, thereby ensuring the accuracy and effectiveness of the electric shock rescue pole during use.

[0066] A specific embodiment may be: two cylindrical positioning holes 340 with a diameter of 5 mm and a depth of 10 mm are provided on the plug 310, with a hole spacing of 30 mm. Correspondingly, two cylindrical positioning posts 130 with a diameter of 4.9 mm and a height of 9.5 mm are provided in the slot 110, with a post spacing of 30 mm. The positioning posts 130 and the positioning holes 340 are clearance-fitted with a clearance of 0.1 mm. This design can provide sufficient limiting effect and facilitate installation and disassembly. At the same time, the positioning posts 130 are slightly shorter than the positioning holes 340, which can ensure that the plug 310 can be fully inserted into the slot 110 and cooperate well with the fixing mechanism of the locking block 320 and the locking hole 120.

[0067] By introducing the design of positioning posts 130 and positioning holes 340, combined with the existing locking block 320 and locking hole 120 mechanism, this application achieves comprehensive positioning in the front-to-back, left-to-right, and up-to-down directions. This multiple positioning mechanism not only improves connection stability but also simplifies the installation process and improves operational efficiency. At the same time, this design maintains a quick-release function, allowing the head accessory 300 with different functions to be quickly replaced as needed, greatly enhancing the universal applicability of the electric shock rescue pole.

[0068] In certain embodiments, reference is made to the accompanying Figure 1 and attached Figure 2 Bosses 350 are further provided on both the left and right sides of the plug 310 . The bosses 350 are located above the locking block 320 and can abut against the top of the slot 110 .

[0069] In this embodiment, the boss 350 is provided to increase the contact area, disperse stress, and assist in installation, thereby improving the stability and reliability of the connection between the head accessory 300 and the head rod 100 .

[0070] The boss 350 and the plug 310 can be integrally formed or separately connected by welding, gluing, or screwing. The boss 350 can be made of the same material as the plug 310, or a material with higher strength or better friction properties, such as nylon or polytetrafluoroethylene.

[0071] The arrangement of boss 350, locking block 320, and locking hole 120 form a coordinated whole. When plug 310 is inserted into slot 110, locking block 320 engages with locking hole 120 under the action of elastic member 330, while boss 350 ultimately rests against the top of slot 110. This design not only increases the contact area but also creates a three-point support structure, significantly improving the stability of the connection.

[0072] During use, the presence of the boss 350 disperses the vertical forces acting on the head accessory 300 toward the top of the slot 110, reducing the pressure on the locking block 320. This force distribution effectively extends the service life of the locking block 320 and the locking hole 120, improving the durability of the entire quick-release connection structure 200. Furthermore, the boss 350 provides a larger force-bearing surface for the user. By applying vertical pressure to the boss 350, the plug 310 can be easily inserted into the slot 110, thus facilitating the user's installation of the head accessory 300 on the head rod 100.

[0073] In certain embodiments, reference is made to the accompanying Figure 7 The electric shock rescue pole further includes a first tail pole 400 , a first end of the first tail pole 400 being hinged to the second end of the head pole 100 so that the first tail pole 400 and the head pole 100 can be folded relative to each other and can be straightly unfolded.

[0074] In this embodiment, the first end of the first tail pole 400 is hingedly connected to the second end of the head pole 100, allowing the two components to rotate relative to each other, thereby achieving both folded and unfolded states. When in use, the first tail pole 400 and the head pole 100 can be straightened out to form a longer rescue pole. When not in use or for portability, the two components can be folded together, significantly reducing the overall length for easier storage and transportation.

[0075] The hinge structure of the present application can be provided with a spherical joint at the connection of the two rods, allowing a wider range of rotation. The hinge can also be designed as a detachable structure for easy maintenance and replacement.

[0076] The hinged design, combined with the quick-release connection structure 200, further enhances the flexibility and practicality of the electric shock rescue pole. To replace the head accessory 300, the first tail pole 400 can be folded to reduce the operating space, and then the head accessory 300 can be replaced using the quick-release connection structure 200. This combined design ensures that the rescue pole strikes an excellent balance between functionality and portability.

[0077] In actual use, the first tail bar 400 and the head bar 100 can be designed with different length ratios as needed. For example, they can be designed to be equal length, with the total length halved when folded. Alternatively, the first tail bar 400 can be designed to be slightly shorter for a more compact design when folded. Typically, the head bar 100 is designed to be 60-80 cm long, and the first tail bar 400 is designed to be 50-70 cm long. This provides sufficient operating length in the unfolded state while still being portable when folded.

[0078] The design of this application solves the inconvenience of carrying and storing traditional fixed-length rescue poles. It ensures the necessary length for use while also improving portability. This is crucial for rapid response rescue operations, making it easier to bring rescue equipment to the scene. Furthermore, when folded, it takes up very little space, facilitating centralized storage and management of equipment.

[0079] In a specific embodiment, the head rod 100 is made of an insulating material with a length of 70 cm, and the first tail rod 400 is made of an insulating material with a length of 60 cm. The two are connected by a hinge made of stainless steel, which is fixed with bolts, and the tightness of the hinge can be adjusted as needed. In the unfolded state, the two rods can form a rescue pole with a total length of 130 cm, which is sufficient to cope with most rescue scenarios. When folding is required, the first tail rod 400 can be rotated 180 degrees toward the head rod 100 so that the two are parallel and fit together. The total length after folding is only 70 cm, which greatly improves portability.

[0080] Compared to traditional fixed-length rescue poles, the foldable design of the present application significantly improves the portability and storage efficiency of the product while maintaining functionality. Traditional rescue poles are usually around 1.5 meters long, which is not convenient to carry and store. Especially in emergency situations, the large size may affect the quick response of rescuers. The design of the present application can reduce the length of the rescue pole by nearly half, making it easier to put it in a vehicle or backpack, greatly improving the maneuverability of the rescue equipment. In addition, this design also leaves room for further improvement, such as adding a locking device at the hinge to ensure stability in the unfolded state; or designing a multi-section folding structure to further increase the length and flexibility of the rescue pole.

[0081] In certain embodiments, reference is made to the accompanying Figure 7 A first locking device 510 is provided at the hinge between the first tail rod 400 and the head rod 100. The first locking device 510 is used to lock the first tail rod 400 and the head rod 100 so that the first tail rod 400 and the head rod 100 remain straight and unfolded.

[0082] In this embodiment, a first locking device 510 is provided at the hinge of the first tail rod 400 and the head rod 100, and is used to lock the two rods. This locking mechanism can ensure that the first tail rod 400 and the head rod 100 remain straight in the unfolded state, preventing accidental folding or shaking. By adding the first locking device 510 at the hinge, the electric shock rescue pole can maintain a stable straight state when in use. This design not only improves the structural strength of the rescue pole, but also enhances the safety and reliability of operation. When rescuers need to use a fully unfolded rescue pole, the first tail rod 400 and the head rod 100 can be locked in a straight position through the first locking device 510, thereby ensuring the accuracy and effectiveness of the rescue operation. At the same time, this locking mechanism also facilitates quick unlocking when not in use, making it convenient for folding, storage and transportation.

[0083] The first locking device 510 can be implemented in a variety of ways. One common design uses a spring pin structure. When the first tail rod 400 and the head rod 100 are unfolded to a straight position, the spring pin automatically pops out and inserts into a pre-set locking hole, achieving locking. Another approach is to use a rotational locking device, which fixes the relative position of the hinge by rotating a locking ring or rod. Alternatively, a snap-on locking device can be used. When the two rods are fully unfolded, the snap automatically engages and is manually released when folding.

[0084] These locking mechanisms form a complete system with the quick-release connection structure 200. The quick-release connection structure 200 allows for the replacement of different head accessories 300, while the first locking device 510 ensures the stability of the entire rescue pole during use. These two features work together to significantly enhance the versatility and operational safety of the electric shock rescue pole. For example, when using a heavier head accessory 300, the presence of the first locking device 510 is particularly important, preventing accidental folding due to the weight, thereby ensuring a smooth rescue operation.

[0085] In practice, the design of the first locking device 510 requires consideration of several factors. First, the locking device should be sufficiently strong to withstand the various external forces encountered during the rescue process. Second, the locking and unlocking operations should be simple and quick, allowing the rescue pole to be quickly deployed or retracted in an emergency. Furthermore, the locking device should be durable and corrosion-resistant to withstand harsh environments. For example, stainless steel or high-strength engineering plastics can be used, and a sealed design can be employed to prevent the intrusion of dust and moisture.

[0086] The operating principle of the first locking device 510 can be further explained as follows: When a rescuer needs to use the fully extended rescue pole, they first unfold the first tail pole 400 and the head pole 100 to a straight position. At this point, the first locking device 510 is automatically activated or activated manually. For example, if a spring pin design is used, the spring pin automatically snaps into the locking hole when the two poles are aligned; if a rotary locking device is used, the operator simply rotates the locking ring to lock. Once locked, the two poles form a rigid connection that can withstand forces in all directions and remain stable. When the rescue pole needs to be folded, the operator releases the lock using the corresponding unlocking mechanism (such as pressing a release button or rotating the locking ring in the opposite direction), and then easily folds the pole.

[0087] This design offers significant advantages over traditional fixed rescue poles. Traditional rescue poles are typically one-piece structures or utilize simple threaded connections, lacking the ability to quickly unfold and fold. The design of the present application not only retains the stability of traditional rescue poles, but also increases portability and operational flexibility. For example, when conducting a rescue in a confined space, the rescue pole can be folded and carried to the scene, then quickly unfolded and locked, greatly improving rescue efficiency. At the same time, the presence of the first locking device 510 also enhances the safety of the rescue pole, preventing accidental folding during use, thereby protecting the safety of both the rescuer and the person being rescued.

[0088] In a specific embodiment, the first locking device 510 can be designed as a spring-driven bidirectional locking pin. The locking pin is installed at the hinged end of the head rod 100 and cooperates with the corresponding locking hole on the first tail rod 400. The diameter of the locking pin is 10 mm and the length is 30 mm. The material selected is 440C stainless steel, which has high strength and good corrosion resistance. There is an operating button with a diameter of 2 mm at each end of the locking pin, and the exposed part of the button is 5 mm long for easy operation. When the first tail rod 400 and the head rod 100 are unfolded into place, the locking pin is automatically inserted into the locking hole under the action of the spring force to achieve locking. The inner wall of the locking hole has been specially treated, and the surface roughness Ra value is controlled within 0.8 μm to reduce friction and extend service life. When unlocking, you only need to press the operating buttons at both ends at the same time to overcome the spring force and retract the locking pin to achieve quick unlocking.

[0089] In certain preferred embodiments, Figure 5 and attached Figure 6The hinges between two adjacent rod bodies (applicable to the head rod 100, the first tail rod 400, the middle rod body 700, the extension rod 710 and the second tail rod 600 mentioned in this application) are provided with grooves 810 and slide rails 820. After the two rod bodies are straightly unfolded, the slide rails 820 on the two rod bodies will be spliced ​​into one piece, and the groove 810 includes a guide portion 811 and a spherical portion 812. The guide portion 811 is located above the spherical portion 812 and is connected to the spherical portion 812. The guide portion 811 extends in the up and down direction and the depth of the recess gradually deepens from top to bottom to the same recess depth as the spherical portion 812.

[0090] A locking device (applicable to the first locking device 510, the second locking device 520 and the third locking device 530 mentioned in this application) is slidably provided between each adjacent rod body. The locking device is slidably provided on the corresponding slide rail 820 and can be moved from the rod body near the top and fixed at the hinge between the two adjacent rod bodies. The locking device is provided with a protrusion 540, which can slide into the guide portion 811 from the top along with the locking device and gradually slide from top to bottom into the spherical portion 812 under the guidance of the guide portion 811 and finally be embedded in the spherical portion 812.

[0091] In actual use, after the two adjacent rods are straightened out, the user slides and fixes the corresponding locking device to the hinge between the two adjacent rods, thereby locking the two rods to keep them straight. Among them, because the spherical portion 812 is closer to the bottom than the guide portion 811, when the user erects the electric shock rescue pole, although the locking device tends to slide downward due to gravity, it remains fixed at the hinge between the two adjacent rods due to the mutual obstruction between the protrusion 540 and the spherical portion 812. When the user needs to fold the electric shock rescue pole, the locking device is pushed upward to make the protrusion 540 disengage from the spherical portion 812, and finally the locking device leaves the hinge between the two adjacent rods, allowing the two adjacent rods to rotate relative to each other.

[0092] It should be noted that the main function of the guide portion 811 is to guide the protrusion 540 to slide and enable it to be smoothly embedded in the spherical portion 812, and to guide the locking device to leave the hinge between two adjacent rods when the protrusion 540 slides out of the spherical portion 812.

[0093] Furthermore, the protrusion 540 may be a sphere capable of rolling relative to the locking mechanism, with an elastic cushioning layer 550 disposed between the sphere and the locking mechanism. As the sphere rolls along the rod surface with the locking mechanism, the sphere compresses the elastic cushioning layer 550, which deforms to absorb the pressure, reducing friction between the sphere and the rod surface, thereby facilitating the sphere's rolling along the rod surface. When the sphere rolls along the locking mechanism to the position of the spherical portion 812, the elastic cushioning layer 550 returns to its original shape and applies an elastic force to the sphere, allowing it to embed within the spherical portion 812.

[0094] It should be noted that the elastic cushion layer 550 can be made of, but is not limited to, rubber or silicone materials.

[0095] By introducing the first locking device 510, the present application not only ensures the stability of the rescue pole during use, but also significantly improves its portability and operational flexibility. This design enables rescuers to perform rescue work more efficiently in various complex environments while also improving the safety of the rescue process. Furthermore, the present application's design also works well with the quick-release connection structure 200, further enhancing the versatility of the electric shock rescue pole and making it adaptable to a wider range of rescue scenarios.

[0096] In certain embodiments, reference is made to the accompanying Figure 3 , Attachment Figure 4 and attached Figure 8 The electric shock rescue pole also includes a second tail pole 600 and an intermediate pole body 700. The first end of the intermediate pole body 700 is hinged to the second end of the head pole 100, and the second end of the intermediate pole body 700 is hinged to the first end of the second tail pole 600 so that the head pole 100, the intermediate pole body 700 and the second tail pole 600 can be folded together and can be unfolded straight.

[0097] In this embodiment, the second tail bar 600 and the intermediate bar body 700 are introduced and connected to the head bar 100 via a hinged connection, making the entire rescue pole foldable. This structural design allows the pole to be unfolded into a straight, long pole when needed, facilitating rescue operations, and can also be folded for easy portability and storage.

[0098] Specifically, the first end of the intermediate rod body 700 is hingedly connected to the second end of the head rod 100, and the second end of the intermediate rod body 700 is hingedly connected to the first end of the second tail rod 600. This hinged structure can be implemented in a variety of ways, such as a pin connection, a hinge connection, or a ball-and-socket connection. Each connection method has its own advantages, such as the simple structure of a pin connection, the stability of a hinge connection, and the flexibility of a ball-and-socket connection.

[0099] The hinged structure allows the head pole 100, middle pole body 700, and second tail pole 600 to rotate relative to each other, thus achieving foldable and unfoldable functions. When in use, the three sections can be unfolded into a straight line; when not in use, they can be folded together, significantly reducing the size of the rescue pole. This design not only improves the portability and storage efficiency of the electric shock rescue pole, but also increases its flexibility.

[0100] To further enhance the stability and ease of use of the rescue pole, a locking device can be installed at the hinge. For example, a spring pin lock, a rotation lock, or a snap lock can be used. These locking devices ensure that the rescue pole remains straight when deployed, improving the safety and precision of operation.

[0101] Furthermore, the intermediate pole 700 can be designed as a multi-segment structure, with each segment also hingedly connected. This not only further reduces the folded volume but also allows the length of the rescue pole to be adjusted according to actual needs. For example, the intermediate pole 700 can be designed with 3-5 segments, each 30-50 cm long. This ensures sufficient working length without compromising the folding effect due to excessive length of a single segment.

[0102] The design of this application effectively addresses the bulk and portability issues of traditional electric shock rescue poles by introducing a multi-section foldable structure. Users can choose the length of the pole to suit specific rescue needs, adapting to different rescue scenarios. For example, in a confined space, only a portion of the pole can be deployed, while the pole can be fully deployed for long-distance operations. This flexibility significantly improves rescue efficiency and its scope of application.

[0103] The foldable design also allows rescuers to quickly deploy and stow the equipment in confined or complex environments. For example, when entering a building or vehicle wreckage for rescue, the rescue pole can be folded and carried, then unfolded upon arrival, greatly improving rescue maneuverability and efficiency.

[0104] Compared to traditional fixed-length electric shock rescue poles, the foldable design of this application significantly improves the portability and applicability of the product while maintaining functionality. Traditional rescue poles often require a fixed length to meet the requirements of the maximum working distance, which makes them bulky and inconvenient to operate when not in full use. The design of this application allows users to adjust the length according to actual conditions, which can not only meet the needs of long-distance operation, but also maintain flexibility when working at close range. This flexible and adjustable feature not only improves rescue efficiency, but also reduces the burden on rescuers, which is conducive to increasing the success rate of rescue.

[0105] In certain embodiments, reference is made to the accompanying Figure 3 , Attachment Figure 4 and attached Figure 8A second locking device 520 is provided at the hinge between the second tail rod 600 and the middle rod body 700, as well as at the hinge between the middle rod body 700 and the head rod 100. The second locking device 520 is used to lock the second tail rod 600, the middle rod body 700 and the head rod 100 so that the second tail rod 600, the middle rod body 700 and the head rod 100 remain straight and unfolded.

[0106] In this embodiment, the problem of multi-section folding and unfolding of the electric shock rescue pole is solved by providing a second locking device 520 at the hinge of the second tail pole 600 and the middle pole body 700, and at the hinge of the middle pole body 700 and the head pole 100. The function of the second locking device 520 is to lock the second tail pole 600, the middle pole body 700 and the head pole 100 so that they can maintain a straight and unfolded state. This design allows the electric shock rescue pole to be folded into a smaller volume when needed, making it easier to carry and store. At the same time, when needed, the various parts can be unfolded and fixed by the second locking device 520 to form a stable long pole structure. This foldable and lockable design increases the practicality and flexibility of the electric shock rescue pole, enabling it to adapt to different usage scenarios and space limitations.

[0107] It should be noted that the specific structure of the second locking device 520 is as described above and will not be repeated here.

[0108] In certain embodiments, reference is made to the accompanying Figure 9 The middle rod body 700 includes multiple extension rods 710, and two adjacent extension rods 710 are hinged so that all the extension rods 710 can be folded together and can be straightly unfolded.

[0109] In this embodiment, by providing multiple extension rods 710 within the intermediate rod body 700 and connecting adjacent extension rods 710 via hinged connections, the extension rods 710 can be both folded together and extended straight. This design increases the overall length of the electric shock rescue pole, making it suitable for rescues at longer distances; it also maintains its foldability for easy portability and storage; the multiple extension rods 710 allow rescuers to adjust the length of the pole according to their needs, increasing rescue flexibility; and the hinged structure provides a more secure connection between the extension rods 710 while also facilitating operation and adjustment.

[0110] Specifically, the intermediate rod body 700 may include two, three, or more extension rods 710, which may be of the same or different lengths. The articulation between the extension rods 710 may be achieved in a variety of ways, such as using hinges, pins, or ball-and-socket structures. Each hinge point may be designed to rotate freely between 0° and 180°, enabling full folding and unfolding.

[0111] To enhance the connection strength between the extension rods 710, reinforcing ribs or high-strength materials can be added at the hinges. At the same time, for ease of operation, a quick locking device, such as a spring lock or a rotary locking device, can be designed at each hinge to enable rescuers to quickly lock or unlock the position of the extension rods 710.

[0112] In addition, the extension rod 710 can be made of lightweight, high-strength materials, such as carbon fiber composite materials or aviation-grade aluminum alloys, to reduce overall weight while ensuring strength. The surface of the extension rod 710 can be coated with insulating material to further improve the safety of the rescue rod.

[0113] This technical solution, combined with the aforementioned quick-release connection structure 200 and foldable design, further enhances the adaptability and practicality of the electric shock rescue pole. The multi-section extension pole 710 allows rescuers to quickly adjust the length of the pole based on different rescue scenarios, accommodating both long-distance rescue needs and flexible use in confined spaces. Furthermore, the foldable design significantly increases the pole's portability, facilitating rapid response to various emergencies.

[0114] In certain embodiments, reference is made to the accompanying Figure 9 A third locking device 530 is provided at the hinge of any two adjacent extension rods 710. The third locking device 530 is used to lock all the extension rods 710 so that all the extension rods 710 remain straight and extended.

[0115] In this embodiment, third locking devices 530 are provided at the hinges between the multiple extension rods 710 of the intermediate rod body 700. These locking devices lock all extension rods 710, ensuring they remain straight and extended. By providing locking devices at the hinges of each adjacent extension rod 710, the entire intermediate rod body 700 maintains a stable, straight configuration after deployment. This design addresses the potential for instability or loosening of the multiple extension rods 710, improving the structural strength and operational reliability of the entire electric shock rescue pole.

[0116] It should be noted that the specific structure of the third locking device 530 is as described above and will not be repeated here.
