Description

Technical Field

[0001] The invention relates to the technical field of power transmission line construction and maintenance, in particular to a portable self-expanding and fastening conductor connection device and a use method thereof. Background Art

[0002] With the continuous development of the power grid system, the construction and maintenance of transmission lines occupy an important position in the modern power industry. Especially in mountainous areas, the construction of power lines needs to cope with complex geographical environments and climate challenges. In recent years, the construction of transmission lines has not only increased the transmission capacity, but also provided guarantees for various industrial and domestic electricity use. However, due to the changeable terrain, especially in mountainous areas, transmission lines often need to cross deep valleys, mountains and other areas with large height differences, which leads to higher requirements on the carrying capacity of equipment. At the same time, under severe weather conditions, especially after the line has been running for a long time, due to the influence of external factors such as lightning strikes, storms or overloads, problems such as wire damage and poor contact at the connection position may occur. In some plain areas, intensive operations of mechanical vehicles may also cause accidental collisions of high-voltage lines, and in severe cases may even cause the lines to burn out or stop operating, thereby affecting the normal supply of electricity, and requiring rapid repair and restoration of power supply.

[0003] In the existing technology, power grid emergency repair mainly relies on hydraulic technology for efficient repair. Hydraulic equipment such as crimping machines and wire repair tools provide feasible emergency solutions when high-voltage lines fail, but these equipment are often large and heavy, especially in complex mountainous areas or difficult-to-reach areas. In actual operations, repair personnel need to carry these equipment, and facing the rugged mountainous terrain, the transportation task becomes particularly arduous. At the same time, these equipment usually rely on more complex operations and require professional training to be proficient in use.

[0004] At the same time, after searching, the patent document with announcement number CN209981501U discloses a new type of wire connection device, which is composed of multiple wire-pressing copper blocks connected together by a base. A wire-pressing bolt installed in a threaded hole is provided on the top of each wire-pressing copper block. Corresponding wiring holes are opened in the insulating shell. The insulating shell is cast by DMC material or equivalent material, which has small size, light weight, high strength, and is convenient for standardization and mass production of products, and improves the traditional wire-exposed bolt fixing method; an insulating transparent protective plate is covered on the top of the insulating shell to isolate the live body from the operator while ensuring that the crimping situation is visible, thereby ensuring their personal safety; an elastic waterproof rubber ring is provided in the wiring hole to prevent water from entering.

[0005] However, although the above device can quickly connect the wires, the overall structure is relatively simple, the connection stability of the wires is poor, and the wire specifications that can be set inside the overall device are fixed, so that the device cannot effectively hold wires of multiple specifications, reducing the versatility of the device.

[0006] Therefore, we propose a portable self-expanding and fastening wire connection device and a use method thereof to solve the above problems. Summary of the invention

[0007] 1. Technical issues to be solved

[0008] In view of the shortcomings of the prior art, the present invention provides a portable self-expanding and tightening wire splicing device and a method of using the same, which makes wire splicing easier and more efficient. The adjustable bolt and sliding roller design can reduce the difficulty of manual operation, realize automatic expansion of the wire, and simplify the splicing process, thus solving the problem in the prior art that when splicing wires, a variety of tools and equipment need to be carried, resulting in complex and cumbersome operations.

[0009] (II) Technical solution

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable self-expanding and fastening wire connection device, comprising two symmetrically arranged trapezoidal pressure plates, the interiors of the two trapezoidal pressure plates are provided with arrangement grooves for matching the arrangement of the wires, and the two trapezoidal pressure plates are provided with a plurality of roller rods arranged at intervals on one side close to each other;

[0011] The two trapezoidal pressure plates are both sleeved with a wire clamp at one end away from each other. The wire clamp is sleeved on the outside of the wire. An adjusting tensioning mechanism is provided between the wire clamp and the trapezoidal pressure plate. The tensioning mechanism is used to adjust the tension of the wire.

[0012] The outer sides of the two trapezoidal pressing plates are jointly sleeved with a long connecting tube, and the long connecting tube is used to hold the wire tightly;

[0013] The two trapezoidal pressure plates are both sleeved with a wire clamp at one end away from the other, the wire clamp is sleeved on the outside of the wire, and an adjusting tensioning mechanism is provided between the wire clamp and the trapezoidal pressure plate;

[0014] The tensioning mechanism is used to adjust the tension of the wire. The wire clamp is arranged on the outside of the trapezoidal pressure plate. When the wire is arranged inside the trapezoidal pressure plate, the wire clamp can be driven longitudinally to stably squeeze the wire inside the trapezoidal pressure plate, or to separate the wire from the trapezoidal pressure plate, so as to complete the positioning and tension adjustment of the wire, so that two adjacent wires can be quickly connected.

[0015] The outer sides of the two trapezoidal pressure plates are jointly sleeved with a long connecting tube, which is used to hold the wires tightly and limit the moving range of the two trapezoidal pressure plates, so that when the two wires move away from each other, they can be restricted by the long connecting tube and complete self-expansion tightening.

[0016] Preferably, a plurality of rolling grooves arranged at intervals are provided on the adjacent sides of the two trapezoidal pressure plates, and the roller rods are rotatably arranged in the rolling grooves;

[0017] A roller rod is rotatably inserted in each of the rolling grooves, and the rod wall of the roller rod can pass through the rolling groove. If there is no external force, the system is in a static state, and there is only a slight contact pressure between the roller rods. When the two trapezoidal pressure plates move relative to each other, the roller rods start to roll under the action of the component force along the inclined surface. Due to the rolling contact between the roller rods, they can effectively transmit this movement to the inclined surface of the other trapezoidal pressure plate. During the rolling process, because the rolling friction coefficient of the roller rods is relatively small, the relative approach movement of the two trapezoidal pressure plates can be achieved relatively smoothly. As the two trapezoidal pressure plates approach each other, the inclined sides of the trapezoid will cause the pressure plates to generate an outward component force in the horizontal direction. This component force acts on the components on both sides of the trapezoidal pressure plates, thereby pushing the components, so that the two trapezoidal pressure plates can push the long connecting tube and complete the connection of the wires.

[0018] Preferably, the adjusting tensioning mechanism comprises a bolt slider and an adjusting bolt, a threaded hole is formed at one end of the trapezoidal pressure plate close to the wire clamp, the threaded end of the adjusting bolt is threadedly penetrated in the threaded hole, the bare rod section of the adjusting bolt is rotatably arranged in the bolt slider, and the adjusting bolt and the threaded hole are threadedly matched, so that when the adjusting bolt is rotated, the adjusting bolt is moved longitudinally as a whole, and the wire clamp is pushed in cooperation with the bolt slider, so that the wire clamp completes the longitudinal movement and clamps the wire to position;

[0019] Positioning rods are fixedly provided on both sides of the bolt slider, and positioning holes are opened at the lower ends of both sides of the wire clamp. The two positioning rods are respectively inserted into the two positioning holes. The plug-in cooperation of the positioning rods and the positioning holes can make the wire clamp cooperate with the bolt slider, so that the movement of the bolt slider drives the wire clamp to move at the same time, thereby improving the convenience of device operation.

[0020] Preferably, a fixed sleeve outside the polished rod section of the adjusting bolt is provided with a rotating block for rotating the adjusting bolt;

[0021] Preferably, the cross-section of the rotating block is circular, and the outer wall of the rotating block is provided with a plurality of anti-skid grooves which are symmetrically arranged around the rotating block. The setting of the rotating block and the anti-skid grooves can drive the adjusting bolt to rotate, thereby improving the operation convenience of the overall device.

[0022] Preferably, one end of each of the plurality of rolling grooves passes through the trapezoidal pressure plate and extends to the outside, and a side plate is provided on the outer cover of the end of the rolling groove. The side plate is semicircular in shape, and the internal thread of the side plate is penetrated by two symmetrically arranged positioning bolts, and the threaded ends of the positioning bolts are threaded on the side of the trapezoidal pressure plate. The side plate is semicircular in shape. This shape design can provide a certain degree of protection for the portion of the roller rod extending out of the trapezoidal pressure plate. The semicircular side plate can prevent external objects from directly colliding with the roller rod, to a certain extent, and reduce the risk of damage to the roller rod due to accidental collision. At the same time, the connection using the positioning bolts can facilitate the disassembly of the rolling rod and the quick removal and replacement of the worn rolling rod.

[0023] Preferably, the threaded end of the adjusting bolt is provided with a pushing protrusion, and the pushing protrusion is used to push the wire.

[0024] Preferably, the inclined surfaces of two adjacent trapezoidal pressing plates are in contact with each other, and under the contact and cooperation of the two inclined surfaces, the two trapezoidal pressing plates can move the wires away from each other by squeezing.

[0025] A method for using a portable self-expanding and fastening wire splicing device, the specific operating steps are as follows:

[0026] S1: Install the three components of the adjusting bolt, the wire clamp and the bolt slider on the trapezoidal pressing plate, fix the adjusting bolt with the trapezoidal pressing plate through the internal threaded hole of the trapezoidal pressing plate, and put the wire clamp on the outer side of the trapezoidal pressing plate under the penetration of the positioning rod and the positioning hole, and then put the wire into the groove set inside the trapezoidal pressing plate and locate it in the wire clamp;

[0027] S2: Rotate the rotating block so that the rotating block drives the adjusting bolt to rotate. The rotating operation of the adjusting bolt can drive the bolt slider, thereby moving the wire clamp up and down, thereby achieving tensioning and fixing of the wire;

[0028] S3: The conductor on the other side is fixed by the same method. Subsequently, the two trapezoidal pressure plates are assembled into the long connecting tube through a precisely designed structure. During this process, the two trapezoidal pressure plates move in opposite directions relative to each other through the rolling contact between the roller rods, gradually increasing the spacing between the two conductor branches, so that the conductor is gradually pushed into the long connecting tube, and finally the self-expansion and tightening fixation of the conductor is achieved.

[0029] (III) Beneficial effects

[0030] Compared with the prior art, the present invention provides a portable self-expanding and fastening wire connection device and a method of using the same, which has the following beneficial effects:

[0031] 1. Through the provided trapezoidal pressure plate, wire clamp, tensioning adjustment mechanism and rotating block, during operation, the operator only needs to manually complete the assembly of various components, and set the wire between the guide clamp and the trapezoidal pressure plate. The operator pushes the two trapezoidal pressure plates, and the horizontal surfaces of the two trapezoidal pressure plates slide away from each other under the inclined surface of the trapezoidal pressure plates themselves, so that the two wires are separated from each other and connected, which greatly simplifies the operation process of wire connection, avoids cumbersome tool carrying and use, makes the work process more efficient and simple, and the operator can complete the task quickly, saving the time of tool handling and adjustment, and improving the overall operation efficiency.

[0032] 2. The conductor is fixed on the trapezoidal pressure plate by means of the trapezoidal pressure plate, adjusting bolt and roller rod, and the design of the trapezoidal pressure plate, adjustable bolt and sliding roller is adopted. The operator controls the fixation of the conductor by manually tightening the adjusting bolt. At the same time, the roller rod makes the conductor more flexible during the connection process, which not only ensures the stability of the conductor fixation, but also provides the flexibility and accuracy of the operation. At the same time, the roller rod makes the conductor easier to adjust during the connection process, simplifies the operation steps and improves the accuracy of the connection.

[0033] 3. Through the trapezoidal pressure plate and the long connecting tube, the device gradually increases the pulling force of the wire. Under the interaction between the inner wall of the connecting tube and the wire, the wire is automatically tightened without external intervention, avoiding the intervention of external forces, simplifying the operation process, and ensuring that the wire can automatically reach a tightened state during the connection process, which not only improves the connection quality, but also enhances the stability and reliability of the connection.

[0034] 4. By using high-strength aluminum materials in the parts that contact the wires, the wires have better conductivity and current-carrying capacity, ensuring the stable operation of the line after connection, improving the conductivity of the connecting part of the wires, ensuring efficient transmission of current, and effectively reducing the resistance of the connection point, ensuring the stability and safety of the power transmission process, and reducing the potential risks in the operation of the power system.

[0035] 5. With the trapezoidal pressure plate and wire clamp, the whole device is light in design and simple in structure. No complicated tools or additional equipment are required for operation, which is suitable for fast on-site operations. At the same time, the portability and simple design make the device particularly suitable for use in various working environments. Operators do not need to carry a large number of tools, can quickly respond to on-site needs, and improve work efficiency, especially in complex or emergency situations, and can complete tasks more efficiently.

[0036] 6. By providing the trapezoidal pressure plate, rolling groove, roller rod, side plate and positioning bolt, and by setting one end of the rolling groove to be open, it is convenient to install the roller rod, and at the same time, the roller rod can be quickly pulled out and replaced after the roller rod is worn for a long time. In addition, the setting of the side plate and the positioning bolt can block the end of the rolling groove, so that the rotation position of multiple roller rods of the trapezoidal pressure plate is stable when the wires are in contact, so that the overall device can be used conveniently.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0044] See also Figure 1-5A portable self-expanding and tightening conductor connection device comprises two symmetrically arranged trapezoidal pressure plates 1, the inclined surfaces of the two adjacent trapezoidal pressure plates 1 are in contact with each other, the two trapezoidal pressure plates 1 are provided with a setting groove for matching the conductor, the two trapezoidal pressure plates 1 are provided with a plurality of rolling grooves 2 arranged at intervals on one side thereof, each rolling groove 2 is provided with a roller rod 3 rotatably penetrated therein, one end of the plurality of rolling grooves 2 penetrates the trapezoidal pressure plate 1 and extends to the outside, the outer side cover of the end of the rolling groove 2 is provided with a side plate 19, the side plate 19 is provided in a semicircular shape, the inner thread of the side plate 19 is provided with two symmetrically arranged positioning bolts 20, the threaded end of the positioning bolt 20 is threadedly arranged on the side of the trapezoidal pressure plate 1 The side plate 19 is provided on the outer side of the end of the rolling groove 2, and mainly plays the role of closing the rolling groove. Since the rolling groove 2 is rotatably penetrated by the roller rod 3, and one end thereof passes through the trapezoidal pressure plate 1 and extends to the outside, the side plate 19 can prevent dust, debris, etc. from entering the rolling groove. For example, in some industrial environments or outdoor environments, the air may contain dust, sand or other tiny particles. If these impurities enter the rolling groove, the friction force of the roller rod 3 during rotation will be increased, and even the roller rod 3 may be stuck and unable to rotate normally. At this time, the existence of the side plate 19 is like a barrier, which effectively avoids the occurrence of this situation and ensures that the roller rod 3 works in a relatively clean environment;

[0045] The side plate 19 is semicircular in shape, and this shape design can play a certain protective role on the portion of the roller rod 3 extending out of the trapezoidal pressure plate 1. The semicircular side plate 19 can prevent external objects from directly colliding with the roller rod 3 to a certain extent, thereby reducing the risk of damage to the roller rod 3 due to accidental collision.

[0046] At the same time, the threaded end of the positioning bolt 20 is threadedly arranged on the side of the trapezoidal pressing plate 1, and its main function is to firmly fix the side plate 19 on the trapezoidal pressing plate 1. By passing the positioning bolt 20 through the side plate 19 and threading it with the trapezoidal pressing plate 1, the side plate 19 can be closely fitted to the end of the rolling groove 2, preventing the side plate 19 from loosening or falling off during the operation of the equipment, and can also facilitate installation and disassembly;

[0047] The inclined surfaces of the two trapezoidal pressure plates 1 are opposite to each other, and the roller rods 3 are in contact with each other. At this time, if there is no external force, the system is in a static state, and there is only a slight contact pressure between the roller rods 3. When the two trapezoidal pressure plates 1 move relative to each other, the roller rods 3 begin to roll under the force component along the inclined surface. Due to the rolling contact between the roller rods 3, they can effectively transfer this movement to the inclined surface of the other trapezoidal pressure plate 1. During the rolling process, because the rolling friction coefficient of the roller rods 3 is relatively small, the relative approach movement of the two trapezoidal pressure plates 1 can be achieved relatively smoothly. As the two trapezoidal pressure plates 1 approach each other, the inclined sides of the trapezoid will cause the pressure plates to generate an outward force component in the horizontal direction. This force component acts on the components on both sides of the trapezoidal pressure plates 1, thereby pushing the components, so that the two trapezoidal pressure plates 1 can push the long connecting tube 5 and complete the connection of the wires);

[0048] The two trapezoidal pressure plates 1 are both sleeved with a wire clamp 4 at one end away from each other. The wire clamp 4 is sleeved on the outside of the wire. An adjusting tensioning mechanism is provided between the wire clamp 4 and the trapezoidal pressure plate 1. The tensioning mechanism is used to adjust the tension of the wire.

[0049] The outer sides of the two trapezoidal pressure plates 1 are jointly sleeved with a long connecting tube 5, which is used to hold the conductor tightly. The adjusting tensioning mechanism includes a bolt slider 6 and an adjusting bolt 7. The threaded end of the adjusting bolt 7 is provided with a pushing protrusion, which is used to push the conductor. A threaded hole 8 is provided at one end of the trapezoidal pressure plate 1 close to the conductor clamp 4. The threaded end of the adjusting bolt 7 is threadedly penetrated inside the threaded hole 8. The light rod section of the adjusting bolt 7 is rotatably arranged inside the bolt slider 6. A rotating hole 12 is provided inside the bolt slider 6. The light rod section of the adjusting bolt 7 is rotatably penetrated in the rotating hole 12. The rotating hole 12 is used to support the rotation of the adjusting bolt 7 (to push the adjusting bolt 7). The protrusion can move longitudinally and push the wire when following the rotation of the adjusting bolt 7. Since the adjusting bolt 7 has a longitudinal movement limit through the threaded hole 8, the pushing protrusion can stably push the wire longitudinally, and try to avoid the wire from deviating when being pushed. At the same time, the pushing protrusion can be made of flexible material and the arc shape of the pushing surface can be modified. The elastic deformation of the material can be used to buffer the pressure on the wire, and the damage caused by direct squeezing of the wire by the hard material can be avoided. At the same time, these shape modifications can make the contact area of ​​the protrusion relatively large when it contacts the wire, thereby reducing the pressure on the wire per unit area);

[0050] Positioning rods 9 are fixedly provided on both sides of the bolt slider 6, and positioning holes 10 are provided at the lower ends of both sides of the wire clamp 4. The two positioning rods 9 are respectively inserted into the two positioning holes 10. A rotating block 18 for rotating the adjusting bolt 7 is fixedly provided on the outer side of the bare rod section of the adjusting bolt 7. The cross section of the rotating block 18 is circular, and the outer wall of the rotating block 18 is provided with a plurality of anti-skid grooves arranged in a symmetrical manner (the positioning rods 9 are inserted into the positioning holes 10, which mainly play a precise positioning function). This design can ensure that the relative position between the bolt slider 6 and the wire clamp 4 is accurate. For example, during installation or adjustment, the cooperation of the positioning rods 9 and the positioning holes 10 can ensure that the wire clamp 4 is horizontally and vertically aligned. The directional position accuracy enables the wire clamp 4 to accurately fix and position the wire, preventing it from shifting during the operation of the equipment, so that when the wire clamp 4 is subjected to external forces, it can better resist these external forces, maintain the structural integrity of the entire device, and ensure the safe fixation of the wire. At the same time, the design of the positioning rod 9 and the positioning hole 10 also facilitates the installation and disassembly of the device. During installation, the operator can first align the positioning rod 9 with the positioning hole 10, and then perform a simple insertion operation to quickly connect the two components together. When disassembly is required, just pull the positioning rod 9 out of the positioning hole 10. The operation is simple and convenient, which improves the efficiency of maintenance and overhaul;

[0051] In addition, the rotating block 18 is mainly used to facilitate the rotation of the adjusting bolt 7. The circular cross-section design allows the operator to hold the rotating block from any direction for operation, which has good operability. Moreover, the circular design is also in line with the principle of ergonomics, which is more comfortable when held by hand and convenient for applying rotational force. The multiple anti-skid grooves arranged in a symmetrical manner on the outer wall of the rotating block 18 can increase the friction between the hand and the rotating block. When rotating the adjusting bolt 7, especially when a large torque is required, the anti-skid groove can effectively prevent the hand from slipping. For example, when the operator has oil on his hands or operates in a humid environment, the anti-skid groove can ensure that the operator can still hold the rotating block stably and apply sufficient rotational force, so that the adjusting bolt 7 can be rotated smoothly, thereby realizing the adjustment of relevant parameters such as the position of the wire clamp 4. Since the rotating block 18 is fixedly sleeved on the outside of the light rod section of the adjusting bolt 7, when the rotating block is rotated, the applied torque can be evenly transmitted to the adjusting bolt 7. This helps to smoothly adjust the rotation of the bolt 7, avoid wear or damage between the adjusting bolt 7 and other components due to uneven torque, and also can more accurately control the rotation angle of the adjusting bolt 7, thereby achieving more precise adjustment of the entire device).

[0052] Before the self-expansion tightening of the wire, the adjusting bolt 7 can be first inserted into the bolt slide 6, and the positioning hole at the lower end of the wire clamp 4 is plugged into the positioning rod 9, so that the wire clamp 4 is connected to the bolt slide 6, and then the wire clamp 4 is sleeved on the outside of the trapezoidal pressure plate 1;

[0053] Next, the wire is placed in the trapezoidal pressure plate 1 and is located in the wire clamp 4, and the rotating block 18 is driven so that the rotating block 18 drives the adjusting bolt 7 to rotate. At this time, through the cooperation between the adjusting bolt 7 and the internal threaded hole 8 of the trapezoidal pressure plate 1, the adjusting bolt 7 pushes the bolt slider 6, so that the bolt slider 6 drives the wire clamp 4 to move longitudinally, so that the wire clamp 4 clamps the wire;

[0054] Then repeat the above operation to connect the other side of the wire with the trapezoidal pressure plate 1, then quickly put the trapezoidal pressure plate 1 on the long connecting tube 5, and push one side of the trapezoidal pressure plate 1. At this time, the two trapezoidal pressure plates 1 are close to each other under the rolling cooperation of multiple roller rods 3. Due to the contact of the inclined surfaces of the two trapezoidal pressure plates 1, the horizontal surfaces of the two trapezoidal pressure plates 1 and the internal wires move away from each other and gradually contact the inner wall of the long connecting tube 5, thereby completing the self-expansion and tightening operation of the wires, so that the wires can be quickly connected.

[0055] A method for using a portable self-expanding and fastening wire splicing device, the specific operation method is as follows:

[0056] S1: Install the three components of the adjusting bolt 7, the wire clamp 4 and the bolt slider 6 on the trapezoidal pressing plate 1, fix the adjusting bolt 7 with the trapezoidal pressing plate 1 through the internal threaded hole 8 of the trapezoidal pressing plate 1, and put the wire clamp 4 on the outside of the trapezoidal pressing plate 1 under the penetration of the positioning rod 9 and the positioning hole 10, and randomly put the wire into the groove set inside the trapezoidal pressing plate 1, and locate it in the wire clamp 4;

[0057] S2: Rotate the rotating block 18 so that the rotating block 13 drives the adjusting bolt 7 to rotate. The rotating operation of the adjusting bolt 7 can drive the bolt slider 6, and then move the wire clamp 4 up and down, thereby achieving tensioning and fixing of the wire;

[0058] S3: The conductor on the other side is fixed by the same method. Subsequently, the two trapezoidal pressure plates 1 are assembled into the long connecting tube 5 through a precisely designed structure. During this process, the two trapezoidal pressure plates 1 move in opposite directions relative to each other through the rolling contact cooperation between the roller rods 3, and the spacing between the two conductor branches is gradually increased, so that the conductor is gradually pushed into the long connecting tube 5, and finally the self-expansion and fixation of the conductor is achieved.

[0059] In summary, the portable self-expanding and tightening wire connection device and its use method, when in use, the three components of the adjusting bolt 7, the wire clamp 4 and the bolt slider 6 are installed on the trapezoidal pressure plate 1, and the position of the adjusting bolt 7 is determined, and then the wire clamp 4 is sleeved on the outside of the trapezoidal pressure plate 1 under the penetration of the positioning rod 9 and the positioning hole 10, and then the wire is put into the groove set inside the trapezoidal pressure plate 1, and is located in the wire clamp 4;

[0060] Finally, two trapezoidal pressure plates 1 are arranged in the long connecting tube 5, and the two trapezoidal pressure plates 1 move in opposite directions relative to each other through the rolling contact cooperation between the roller rods 3, gradually increasing the distance between the two wire branches, so that the wires are gradually pushed into the long connecting tube 5, and finally the self-expansion and fixation of the wires are realized.
