Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power construction supplies, in particular to a wire tightener. BACKGROUND

[0002] The wire tightener is a commonly used wire tightening tool in power and communication line construction and maintenance, which is mainly used for high-altitude wire tightening operation, wire removal operation, tower wire adjustment, ground wire tightening, etc. Its main function is to hook the cable with a hook and tighten the cable through an adjusting device, so as to quickly and effectively tighten and fix the cable, thereby achieving the purpose of fixing or tensioning. The wire tightener is widely used in the installation and maintenance of power and communication lines, as well as steel cable tensioning operations in the construction industry.

[0003] During the transmission line construction operation, the wire tightener can tighten the wire, adjust the position of the equipment or material, and also can replace the insulator. The specific method is to first loosen the steel wire rope or iron wire on the wire tightener, fix it to the cross arm, clamp the wire with a wire clamp, and then turn the special spanner, so that the wire can be tightened.

[0004] The wire tightener also has the function of hoisting heavy objects, which is similar to the method and effect of a hand-operated hoist. However, it cannot hoist heavy objects and can only hoist light objects. The wire tightener has the characteristics of high quality and powerful function, which can greatly improve the work efficiency of power workers. However, the current wire tightener has a big disadvantage: it needs a lot of force to tighten the wire, especially when the wire diameter is thick and the span is large, which is more laborious and time-consuming.

[0005] At present, most of the traditional mechanical pure manual wire tighteners are used in the power line maintenance and construction of the domestic power system. The wire tightener is not convenient to carry during operation and is not convenient to fix during wire tightening, which leads to low stability and long process time. The tower operation personnel not only have high labor intensity and low work efficiency, but also have a small amount of power and hydraulic as external force driven wire tightener. The electric wire tightener has a battery power supply, the power supply has a charging mobile type and a wired charging type, the motor and the wire tightener are an integral whole, the weight is too large, and the hydraulic as external force driven wire tightener will leak after a long time, which brings safety hazards. SUMMARY

[0006] In view of the above or existing problems in the prior art, the present application is proposed.

[0007] Therefore, the purpose of the present application is to provide a wire tightener which can connect the cable that needs to be tightened and drive the gear engagement through different driving modes to amplify the transmission torque to pull the cable and achieve wire tightening.

[0008] To solve the above technical problems, the application provides the following technical scheme: a line tightener, comprising a transmission assembly, the transmission assembly comprising a housing, a driving shaft connected to the inside of the housing, a driving gear connected to the outside of the driving shaft for transmitting power, and a winding component meshing with the driving gear;

[0009] The winding component comprises a connecting shaft connected to the inside of the housing, a driven gear connected to the outside of the connecting shaft, and a winding part connected to the outside of the connecting shaft; the driven gear is meshingly connected to the driving gear;

[0010] When the driving gear rotates, the driven gear can drive the winding part to rotate relative to the driving gear.

[0011] The application has the beneficial effect that: by arranging the driving gear and the winding component, the driving gear is driven to rotate the winding component by gear ratio transmission output, and a larger force is converted from a smaller force, when the line needs to be tightened, the winding component is driven to rotate by transmitting driving force to the driving gear to wind the cable on the winding part, which can not only realize fast cable tightening operation, but also amplify the driving force through gear ratio, so that the winding part rotates to tighten the line, and the labor-saving effect is achieved to a certain extent.

[0012] In view of the above technical problems that the existing winding component needs to be limited and prevented from being detached to prevent the winding part from accidentally reversing and causing the cable to fall off when the line is temporarily stopped, and the line tightening operation needs to be easier, the limiting assembly in the application is proposed.

[0013] To solve the above technical problems, the application also provides the following technical scheme: a line tightener, comprising: a limiting assembly;

[0014] The limiting assembly comprises a support shaft connected to the inside of the housing, a gear set connected to the outside of the support shaft, and a limiting piece connected to the gear set, and the gear set is meshed with the driving gear;

[0015] The gear set can generate reverse rotation relative to the driving gear when the driving gear rotates, and drive the limiting piece to limit the rotation direction of the driving gear.

[0016] As a preferred scheme of the line tightener, the limiting piece comprises a pawl part sleeved with the outside of the support shaft, a ratchet part meshing with the pawl part, and a linkage gear connected with the ratchet part;

[0017] The linkage gear is meshingly connected with the gear set;

[0018] The linkage gear can drive the ratchet part to rotate, and the pawl part can engage with the ratchet part and limit the rotating direction of the driving gear.

[0019] As a preferred scheme of the line tightener, the gear set comprises a connecting gear connected to the outside of the support shaft and a reversing gear.

[0020] The connecting gear is engaged with the driving gear, and the reversing gear is engaged with the linkage gear.

[0021] As a preferred scheme of the line tightener, the limiting member further comprises a shaft sleeve.

[0022] The shaft sleeve passes through the ratchet part and the linkage gear and is arranged outside the driving shaft.

[0023] As a preferred scheme of the line tightener, the limiting assembly further comprises an operation part.

[0024] The operation part is connected with the pawl part, and the operation part is arranged on the side of the pawl part away from the ratchet part.

[0025] When the operation part generates a rotating motion, the pawl part can be driven to disengage from the ratchet part, and the limitation on the rotating direction of the driving gear is released.

[0026] Another beneficial effect of the present application is that the gear set and the limiting member can rotate relative to the driving gear, so that the limiting member and the driving gear can be engaged and limited, and the driving gear can only rotate forward, thereby realizing the line tightening operation. When it is necessary to disengage, the pawl part can be rotated to disengage from the ratchet part, so that the ratchet part loses the force to prevent the driving gear from rotating reversely, thereby enabling the driving gear to drive the winding member to rotate reversely and release the cable.

[0027] In view of the above technical problems of the existing line tightener that needs external force to drive during the line tightening operation and needs to save effort and be easy to operate during the line tightening operation, the driving assembly in the present application is proposed.

[0028] To solve the above technical problems, the present application further provides the following technical scheme: a line tightener comprising a driving assembly.

[0029] The driving assembly comprises a manual handle connected to the outside of the driving shaft.

[0030] As a preferred scheme of the line tightener, the line tightener further comprises a driving assembly.

[0031] The driving assembly comprises an electric connection part connected to the outside of the driving shaft.

[0032] Another advantage of the present application is that when the cable tightener needs external force to drive, the manual handle can be connected to the driving gear through the driving shaft, and the driving force for the movement of the driving gear is provided by the user holding the manual handle to rotate, and when more driving force is needed, the power equipment such as a power drill is connected to the power connection part by using a tool, and the rotation generated by the power equipment is used as a power source to transmit to the driving gear through the power connection part and the driving shaft, and then the winding member generates corresponding rotation to realize more labor-saving cable tightening operation.

[0033] In view of the above technical problems that the corresponding cable end needs to be connected when the cable is tightened, and the connection needs to be stable and efficient when the tightening operation is performed, the connection assembly in the present application is proposed.

[0034] To solve the above technical problems, the present application also provides the following technical solutions: a cable tightener comprising a connection assembly;

[0035] The connection assembly comprises a first connecting part and a second connecting part;

[0036] The first connecting part comprises a rotating shaft connected to the right side of the shell, and a cable tightening hook connected to the outside of the rotating shaft;

[0037] The second connecting part comprises a fixed rod connected to the inside of the shell, a steel rope connected to the fixed rod, and a wire clamp connected to the steel rope.

[0038] As a preferred scheme of the cable tightener, the end of the steel rope away from the fixed rod is connected to the winding part;

[0039] When the winding part rotates, the end of the steel rope close to the winding part can be wound on the winding part.

[0040] The beneficial effects of the present application: through the meshing transmission design of the driving gear and the driven gear, the input torque is amplified by the gear ratio, the human demand is significantly reduced, and the labor-saving tight line of the single-person operation coarse wire diameter and long span cable is realized; through the reverse meshing linkage of the gear set, the ratchet part and the pawl part, a one-way locking mechanism is formed, the cable is prevented from loosening accidentally, and the safety of high-altitude or complex terrain operation is ensured; combined with the dual-mode driving design of the manual handle and the electric connection part, flexible operation in the scene without power supply is supported, and high-efficiency power can be provided by external power equipment, which greatly shortens the operation time; further through the tight line hook and the clamp hinged by the shaft, the dual-function extension of cable tensioning and light lifting is realized, the linkage of the steel rope and the winding part ensures uniform transmission of traction force, and the pulley structure reduces friction loss; the components cooperate with each other, break through the limitations of single function and laborious operation of the traditional tight line device, form a labor-saving, safe, efficient and multipurpose comprehensive tight line device structure, and are suitable for complex operation scenes in many fields, effectively reduce the labor intensity and improve the operation efficiency.

[0048] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0049] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be appreciated that the present application can be practiced in a variety of ways beyond the specific details set forth herein, assuming that the fundamental underlying principles are maintained. It should also be appreciated that the description set forth herein is not intended as a limitation on the scope of the present application but is intended to provide a description of one or more implementations thereof.

[0050] Secondly, the "one embodiment" or "an embodiment" as referred to herein covers a specific implementation, which can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification does not refer to the same embodiment, nor is it mutually exclusive with other embodiments.

[0051] Reference Signs List Figures 1-3 For the first embodiment of the present application, the embodiment provides a line tightener, which can realize winding and tightening through gear transmission engagement, comprising a transmission assembly 1, which comprises a shell 11, a driving shaft 12 connected to the inside of the shell 11, a driving gear 13 connected to the outside of the driving shaft 12 for transmitting power, and a winding member 14 engaged with the driving gear 13.

[0052] The driving gear 13 in the embodiment is actually a transmission structure arranged on the line tightener, which is used to transmit driving force to the winding member 14 for tightening operation. In an implementation, the driving gear 13 can be a gear structure with larger size and number of teeth, and is connected to the driving shaft 12.

[0053] The shell 11 in the embodiment is actually two sets of connecting plates arranged outside the transmission assembly 1 and the limiting assembly 2, and a plurality of sets of supporting cross beams are arranged between the sides of the two sets of connecting plates close to each other, which contain the transmission assembly 1 and the limiting assembly 2 to play a protective role; at the same time, support holes are respectively formed on the outside of the two sets of connecting plates, which are opposite to the positions of the driving shaft 12, the supporting shaft 21 and the winding part 143, so that the shaft bodies are inserted therein to play a rotating support role.

[0054] Further, the winding member 14 comprises a connecting shaft 141 connected to the inside of the shell 11, a driven gear 142 connected to the outside of the connecting shaft 141, and a winding part 143 connected to the outside of the connecting shaft 141; the driven gear 142 is engaged with the driving gear 13.

[0055] Further, when the driving gear 13 rotates, the driven gear 142 can drive the winding part 143 to produce a rotating and tightening motion relative to the driving gear 13.

[0056] The driving gear 13 and the driven gear 142 in the embodiment are actually two groups of gears arranged in parallel, and the two groups of gears are meshed, and the driving force is transmitted to the winding part 143 through gear meshing transmission to drive the winding part 143 to rotate for tightening operation; the winding part 143 can be a wire roller structure with two end limiters and is fixed outside the driven gear 142 to rotate with the driven gear 142.

[0057] Specifically, the gear ratio between the driving gear 13 and the driven gear 142 is 3:1 or 5:1, and using a large gear as a transmission source can more effectively transmit power to a small gear, avoiding excessive energy loss in the transmission process, and achieving the effect of saving labor.

[0058] Referring to Figure 3 When the line needs to be tightened, the external driving force is transmitted to the driving gear 13 through the driving shaft 12, and then the driving gear 13 is driven to rotate clockwise, the driven gear 142 meshes with the driving gear 13, and rotates when the driving gear 13 rotates, and then the winding part 143 rotates to tighten the cable connected to the winding part 143. When the line needs to be loosened, the driving gear 13 is driven to rotate counterclockwise, and then the driven gear 142 and the winding part 143 rotate counterclockwise, and the wire wound on the winding part 143 is released, and the line is loosened.

[0059] In summary, through the gear meshing design of the driving gear 13 and the winding part 14 in the transmission assembly 1, that is, by changing the gear ratio, the smaller input force is amplified to a larger output torque, which significantly reduces the labor demand and achieves the labor-saving effect of tightening operation, especially suitable for cable operation with large line diameter and large span, and solves the technical problems of traditional line tightener.

[0060] Embodiment 2, referring to Figures 1-5 This embodiment is the second embodiment of the application, which is based on the previous embodiment, but further includes movement limitation of the gear transmission tightening to ensure stable tightening. In the previous embodiment, the line tightener includes a limiting assembly 2.

[0061] Further, the limiting assembly 2 includes a support shaft 21 connected to the inside of the housing 11, a gear set 22 connected to the outside of the support shaft 21, and a limiting piece 23 connected to the gear set 22, and the gear set 22 meshes with the driving gear 13.

[0062] Further, the gear set 22 can produce reverse rotation relative to the driving gear 13 when the driving gear 13 rotates, and drive the limiting piece 23 to limit the rotation direction of the driving gear 13.

[0063] Specifically, the limiting piece 23 comprises a pawl part 231 sleeved with the outer side of the supporting shaft 21, a ratchet part 232 engaged with the pawl part 231, and a linkage gear 233 connected with the ratchet part 232.

[0064] The pawl part 231 in the embodiment actually comprises a sleeve arranged outside the supporting shaft 21, and a pawl structure engaged with the ratchet part 232 is arranged outside the sleeve, which is used for limiting and supporting the ratchet part 232; the ratchet part 232 is actually a ratchet structure arranged outside the shaft sleeve 234.

[0065] Further, the linkage gear 233 is engaged with the gear set 22.

[0066] Specifically, the linkage gear 233 can drive the ratchet part 232 to rotate, and the pawl part 231 can engage with the ratchet part 232 and limit the rotating direction of the driving gear 13.

[0067] Further, the gear set 22 comprises a connecting gear 221 connected with the outer side of the supporting shaft 21 and a reversing gear 222.

[0068] Further, the connecting gear 221 is engaged with the driving gear 13, and the reversing gear 222 is engaged with the linkage gear 233.

[0069] The connecting gear 221 and the reversing gear 222 in the embodiment are actually two groups of gear structures arranged in front and back with the supporting shaft 21 as the axis, and the gear ratio between the reversing gear 222 and the connecting gear 221 is 5:1.

[0070] Specifically, when the driving gear 13 rotates, the connecting gear 221 can generate a rotating motion opposite to the rotating direction of the driven gear 142 through engagement, and at the same time, affected by the arrangement relationship between the connecting gear 221 and the reversing gear 222, when the connecting gear 221 rotates, the force acting on it is transmitted through the supporting shaft 21 to drive the reversing gear 222 to rotate, and the reversing gear 222 is engaged with the linkage gear 233, thereby driving the linkage gear 233 to rotate.

[0071] Specifically, as shown in the figure, Figure 3 the connecting gear 221 is engaged with the inner part of the driving gear 13, and the linkage gear 233 is engaged with the right part of the reversing gear 222, so that the ratchet part 232 is driven to rotate in the same direction as the driving gear 13 through the cooperation of the connecting gear 221, the reversing gear 222 and the linkage gear 233.

[0072] Further, the limiting piece 23 further comprises a shaft sleeve 234;

[0073] Further, the shaft sleeve 234 passes through the ratchet part 232 and the linkage gear 233, and is rotatably arranged outside the driving shaft 12.

[0074] Further, the limiting assembly 2 further comprises an operating part 24.

[0075] The operating part 24 in the embodiment is actually a connecting rod structure arranged outside the pawl part 231, which is used to drive the pawl part 231 to rotate along the support shaft 21, so as to separate the pawl part 231 from the ratchet part 232.

[0076] Further, the operating part 24 is connected with the pawl part 231, and the operating part 24 is arranged on the side of the pawl part 231 away from the ratchet part 232.

[0077] Specifically, when the operating part 24 generates a rotary motion, the pawl part 231 can be driven to disengage from the ratchet part 232, so as to release the limitation on the rotary direction of the driving gear 13.

[0078] In the first embodiment, the ratchet limiting rotation is used to realize the tight line when the tight line is needed. Specifically, as shown in Figures 1-4 When the tight line is performed, the manual handle 31 or the electric connection part 32 of the driving assembly 3 drives the driving shaft 12 to rotate clockwise, so as to drive the driving gear 13 to rotate synchronously; the driving gear 13 is engaged with the driven gear 142 of the winding part 14, the torque is amplified through the gear ratio, so that the driven gear 142 and the winding part 143 rotate quickly in the same direction, the steel rope 422 fixed to the winding part 143 rotates gradually to be wound, the clamping part 423 approaches the shell 11, so as to tighten the cable such as the power conductor.

[0079] Referring to Figure 3 During the tight line process, the clockwise rotation of the driving gear 13 drives the connecting gear 221 of the driving gear set 22 to rotate counterclockwise through the engagement; the connecting gear 221 drives the reversing gear 222 to rotate counterclockwise through the support shaft 21, the reversing gear 222 is engaged with the linkage gear 233, so as to drive the linkage gear 233 to rotate clockwise, the linkage gear 233 is fixedly connected with the ratchet part 232, the clockwise rotation of the ratchet part 232 is blocked by the pawl of the pawl part 231, so as to form the one-way locking. At this time, if the driving gear 13 loses the driving force, the pawl part 231 will resist the ratchet part 232 to prevent the counterclockwise reverse rotation, and then the rotation direction of the driving gear 13 is locked through the transmission chain of the linkage gear 233→the reversing gear 222→the connecting gear 221, so as to prevent the cable from loosening.

[0080] In the second embodiment, when the cable needs to be loosened, the operating part 24 is pushed to separate the pawl from the ratchet structure, and then the cable is loosened by rotating. Specifically, when the cable needs to be released, the operating part 24 of the limiting assembly 2 is pushed outward by the operator, and the pawl part 231 is rotated around the support shaft 21 by the lever principle, so that the ratchet teeth are disengaged from the ratchet part 232; at this time, the one-way locking function of the ratchet part 232 is released, and the linkage gear 233 and the reversing gear 222 can be freely rotated, and the reverse movement of the drive gear 13 is no longer restricted.

[0081] After the limiting is released, the operator drives the drive shaft 12 to rotate counterclockwise by the manual crank 31 or the electric connection part 32, and the drive gear 13 rotates counterclockwise; the driven gear 142 and the winding part 143 rotate counterclockwise under the reverse drive, release the wound steel rope 422, and the wire clamp 423 extends away from the shell 11 along with the steel rope 422, and the cable gradually loosens; after the cable is loosened, the operating part 24 is loosened, and the pawl part 231 is re-engaged with the ratchet part 232 under the action of the spring return device, and the limiting function is restored.

[0082] In summary, on the basis of the previous embodiment, the limiting assembly 2 is added, and under the reverse meshing drive of the drive gear 13 and the gear set 22, the gear set 22 drives the linkage gear 233 through the connecting gear 221 and the reversing gear 222, and the ratchet part 232 and the pawl part 231 form a one-way locking mechanism; when the drive gear 13 rotates clockwise, the pawl part 231 is clamped into the tooth groove of the ratchet part 232, preventing reverse movement; when the cable is loosened, the operating part 24 is pushed to disengage the pawl part 231 by the lever principle, realizing controllable release, and the linkage cooperation eliminates the risk of accidental loosening of the cable, especially suitable for high-altitude or complex terrain operation, greatly improving the safety on the basis of saving labor.

[0083] Embodiment 3, refer to Figures 1-6 This is the third embodiment of the application, which is based on the previous embodiment, but further improves the diversity of the drive mode of the line tightener, which can provide a manual way to drive the line tightener, including the drive assembly 3.

[0084] Further, the drive assembly 3 includes a manual crank 31 connected to the outer side of the drive shaft 12.

[0085] In the first embodiment, when the line needs to be tightened, manual rotation is used to achieve the tightening. Specifically, the operator holds the manual handle 31 and applies a rotating force, the drive shaft 12 is rotated clockwise, and the drive gear 13 is synchronously rotated; the drive gear 13 is engaged with the driven gear 142, and the torque is amplified by a gear ratio of 5:1, so that the driven gear 142 and the winding part 143 rotate quickly in the same direction; when the winding part 143 rotates, the steel rope 422 is gradually wound thereon, the line clamp 423 moves towards the shell 11, and the cable is tensioned; during this process, the clockwise rotation of the drive gear 13 drives the connecting gear 221 of the drive gear set 22 to rotate counterclockwise, the support shaft 21 drives the linkage gear 233 to rotate clockwise through the reversing gear 222, and the ratchet part 232 is synchronously rotated; the pawl part 231 clamps the ratchet teeth of the ratchet part 232, forming one-way locking, preventing the drive gear 13 from reversing, and ensuring that the cable remains in a tensioned state.

[0086] In summary, the drive assembly 3 directly links the drive gear 13 through the drive shaft 12 through the manual handle 31, which is suitable for power-free scenes or small load operations. Through the seamless linkage of the drive shaft 12 and the gear part, the tool application scenarios are expanded, the flexibility and high-strength operation requirements are considered, and the operation efficiency is significantly improved.

[0087] Embodiment 4, with reference to Figures 1-6 This embodiment is the fourth embodiment of the present application, which is based on the previous embodiment, but further improves the diversity of the line tightener driving mode, which can provide an electric driving mode to drive the line tightener, including the drive assembly 3.

[0088] Further, the drive assembly 3 includes an electric connection part 32 connected to the outside of the drive shaft 12.

[0089] The electric connection part 32 in this embodiment is actually a connection structure connected to the power equipment at the end of the drive shaft 12. The power equipment can be a handheld electric device, such as a 24V or 36V power above 500W lithium battery drill as a driving external force. The connection structure is used to connect the power equipment and the drive shaft 12, and is used to transmit the electric driving force.

[0090] In the first embodiment, when the line needs to be tightened, the electric rotation tightening is implemented. Specifically, the output end of the electric power equipment such as a hand drill is connected with the electric connection part 32 through a connecting tool such as a hexagonal plug or a quick release clamping groove, and after the hand drill is started, the high-speed rotating torque output by the hand drill is transmitted to the drive gear 13 through the drive shaft 12; the drive gear 13 rotates through the meshing drive driven gear 142 and the winding part 143, the steel rope 422 is quickly wound, the traction clamp 423 moves towards the shell 11, and efficient tightening is realized; in the electric drive mode, the shaft sleeve 234 isolates the ratchet part 232 from the drive shaft 12, preventing the gear from being damaged due to overload; the pawl part 231 is kept engaged with the ratchet part 232, preventing the cable from loosening; if the line needs to be loosened, the pawl part 231 is disengaged from the ratchet part 232 by operating the operation part 24, and the drive shaft 12 is rotated counterclockwise to release the steel rope 422.

[0091] In summary, the drive assembly 3 is connected with the electric power equipment such as the hand drill through the electric connection part 32, a larger driving force is transmitted through the drive shaft 12, the shaft sleeve 234 isolates the electric drive from the ratchet part 232, preventing overload damage; through the seamless linkage of the drive shaft 12 and the gear part, the tool application scenarios are expanded, the flexibility and high-intensity operation requirements are considered, and the operation efficiency is significantly improved.

[0092] Embodiment 5, refer to Figures 1-6 This is the fifth embodiment of the application, which is based on the previous embodiment, but further improves the connection stability between the line tightener and the cable, including the connection assembly 4.

[0093] Further, the connection assembly 4 includes a first connection part 41 and a second connection part 42.

[0094] Further, the first connection part 41 includes a rotating shaft 411 connected with the right side of the shell 11, and a tightening hook 412 connected with the outer side of the rotating shaft 411.

[0095] The tightening hook 412 in this embodiment is actually a kind of hook structure, which can be used to connect with the cable at the tightening position.

[0096] Further, the second connection part 42 includes a fixed rod 421 connected with the inside of the shell 11, a steel rope 422 connected with the fixed rod 421, and a clamp 423 connected with the steel rope 422.

[0097] The wire clamp 423 in the embodiment is actually a kind of pulley-connected linkage clamping structure arranged outside the steel cord 422, which comprises two groups of vertically arranged linkages and horizontal linkages connected with the two groups of vertical linkages respectively, the space between the two groups of horizontal linkages is a wire harness clamping space, by placing the wire harness between the two groups of horizontal linkages, under the pulling action of the steel cord 422, a force opposite to the wire harness is generated, so that the linkage is deformed to shrink the clamping space, thereby achieving the effect of automatic locking, the linkage clamping structure can reduce the friction by connecting the steel cord 422 through the pulley, and can be pulled out a certain length under the action of the steel cord 422 to connect the cable to be tightened; when the winding part 143 is rotated to wind the steel cord 422 on the winding part, the connected cable is pulled to the wire tightener direction to realize the tightening operation as the length of the steel cord 422 is shortened.

[0098] Further, the end of the steel cord 422 away from the fixed rod 421 is connected with the winding part 143.

[0099] Further, when the winding part 143 rotates, the end of the steel cord 422 close to the winding part 143 can be wound on the winding part 143.

[0100] The steel cord 422 in the embodiment is actually arranged outside the fixed rod 421 through a wire clamp sleeve at one end, and is inserted into a hole in the wire roller at the other end, and is fixedly connected with the winding part 143 by interference fit to prevent disengagement.

[0101] In the first embodiment, the tightening hook 412 is connected with the cable to realize tightening when the cable needs to be tightened. Specifically, the tightening hook 412 is hinged to the housing 11 through the rotating shaft 411, and hooks the cable to be tightened; the wire clamp 423 is connected with the winding part 143 through the steel cord 422, and clamps the other cable; the rotating shaft 411 allows the tightening hook 412 to rotate by a certain angle to adapt to different cable directions, and the operator can rotate the driving shaft 12 clockwise by hand through the manual crank 31, or drive the driving gear 13 to rotate synchronously by connecting the electric power equipment such as electric drill through the electric connection part 32;

[0102] The driving gear 13 is engaged with the driven gear 142 to drive the winding part 143 to rotate in the same direction after amplifying the driving torque; when the winding part 143 rotates, the steel cord 422 is gradually wound thereon, and the wire clamp 423 is pulled towards the housing 11, so that the cable is tightened; the gear set 22 drives the linkage gear 233 through the connecting gear 221 and the reversing gear 222, the ratchet part 232 is engaged with the pawl part 231 to form one-way locking, so as to prevent the cable from loosening; when loosening the cable, the pawl disengagement is actuated to disengage the pawl, and the winding part 143 is reversely driven to release the steel cord 422.

[0103] In the second embodiment, the tight line hook is used to connect the goods when the heavy object needs to be lifted. Specifically, the tight line hook 412 hooks the fixed support point such as the tower cross arm, and the wire clamp 423 is connected to the lightweight heavy object such as the insulator or tool through the steel rope 422; the wire clamp 423 adopts a pulley structure with self-locking function to reduce friction and prevent slipping; consistent with the cable tightening operation, the drive shaft 12 is driven by the manual handle 31 or the electric connection part 32 to provide manual or electric drive rotary power; the drive gear 13 amplifies the torque through the gear ratio, drives the winding part 143 to rotate clockwise, the steel rope 422 is wound, the wire clamp 423 is moved to the shell 11, and the heavy object is lifted to the target height; the ratchet part 232 is engaged with the pawl part 231 to ensure that the steel rope 422 is not loosened accidentally when the heavy object is suspended; the rotating shaft 411 allows the tight line hook 412 to be flexibly adjusted in angle to adapt to complex lifting scenarios.

[0104] In summary, on the basis of the previous embodiment, the connection assembly 4 is optimized to link the tight line hook 412, the wire clamp 423, the steel rope 422, and the winding part 143 to ensure stable cable connection and expand to the lightweight heavy object lifting scenarios such as insulators and tools. The pulley structure of the wire clamp 423 reduces the friction, further improves the multifunctionality and operation adaptability of the tool on the basis of retaining the labor-saving, anti-loosening, and efficient driving, and meets the needs of multiple fields such as power, communication, and construction.
