Description

Technical Field

[0001] This application relates to the field of power grid guy wire technology, specifically to a guy wire device. Background Technology

[0002] In power grid systems, power distribution requires the installation of network cables. Because these cables are relatively long, they are inconvenient to transport or handle.

[0003] To address the aforementioned problems, existing technologies generally employ a cable-pulling tool to transport the network cable. This tool includes a support and a roller, with the roller rotatably connected to the support via a pivot. The network cable is wound around the outer wall of the roller. When using this tool, rotating the roller forward retracts the network cable, while rotating it in reverse releases it.

[0004] However, during the use of this cable pulling tool, when the network cable does not need to be released, the roller will spontaneously rotate relative to the bracket, causing the network cable to be released and spread out, which is not convenient for the network cable pulling work. Summary of the Invention

[0005] This application provides a cable pulling device. When using this device for cable pulling, the winding assembly can be controlled to remain stationary relative to the base or to rotate relative to the base during the cable pulling process. Thus, when the cable does not need to be released, the winding assembly will not spontaneously rotate relative to the base. In other words, the cable can be manually controlled to be wound up or released, thereby facilitating cable pulling operations.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a wire pulling device, comprising: a base, a winding assembly, and a limiting assembly. The winding assembly is rotatably connected to the base.

[0021] The connector has a travel groove on the side near the limiting member; the end of the limiting member near the connector is inserted into the travel groove so that the end of the limiting member near the connector is always located in the travel groove.

[0022] As an optional implementation, the wire pulling device includes a wire clamping assembly;

[0023] The wire clamping assembly includes a connecting seat, a wire clamping plate, and a wire clamping post; the connecting seat is fixedly connected to the limiting assembly, and the side of the wire clamping plate is fixedly connected to the connecting seat;

[0024] The space between the first end of the clamping post and the clamping surface of the clamping plate is used for threading the wire; the first end of the clamping post abuts against or separates from the clamping surface.

[0025] As an optional implementation, the wire clamping assembly further includes a first support plate, a second support plate, a third support plate, an elastic element, a snap-fit ​​rod, and a snap-fit ​​assembly;

[0026] The first support plate and the second support plate are arranged opposite to each other, and one side of the first support plate and one side of the second support plate are both fixedly connected to the clamping surface; the side of the first support plate away from the clamping surface and the side of the second support plate away from the clamping surface are both fixedly connected to the same surface of the third support plate; the first support plate, the second support plate and the third support plate form a wire-passing channel; the third support plate is provided with a through hole;

[0027] The second end of the clamping post is fixedly connected to the middle of the side of the snap-fit ​​rod.

[0031] As an optional implementation, both the first end of the clamping post and the clamping surface are provided with wire grooves;

[0032] When the first end of the clamping post abuts against the clamping surface, the two wire grooves enclose to form a threading hole, which is used to thread the wire.

[0033] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0034] The cable pulling device includes a base, a winding assembly, and a limiting assembly. The cable can be wound around the winding assembly, which serves as an attachment point for the cable, thus enabling the cable to be wound up, facilitating its storage and transportation.

[0035] Because the winding assembly is rotatably connected to the base, during the use of the cable pulling device, rotating the winding assembly forward can retract the cable, and rotating it in the reverse direction can release the cable. This facilitates the retraction and release of the cable.

[0036] Because the limiting component is fixedly connected to the base; the limiting component includes a limiting member, which abuts against or separates from the winding assembly; when the limiting member abuts against the winding assembly, the winding assembly is relatively stationary with respect to the base; when the limiting member separates from the winding assembly, the winding assembly can rotate relative to the base. This allows for manual control of the winding assembly.

[0037] The winding assembly can be stationary or rotating relative to the base. Specifically, when the limiting member abuts against the winding assembly, a large pressure is generated between the limiting member and the winding assembly, thus generating a large static friction force. Under the action of this static friction force, the winding assembly remains relatively stationary with respect to the base.

[0038] When the limiting member separates from the winding assembly, there is no pressure between the limiting member and the winding assembly, so there is no static friction between the limiting member and the winding assembly. At this time, the winding assembly can rotate relative to the base.

[0039] When using this cable-pulling tool, the winding assembly will not rotate spontaneously relative to the base when the cable does not need to be released. This means the cable can be manually controlled to be wound or released, facilitating cable laying operations. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0051] In existing technologies, a puller is generally used to transport network cables. This puller includes a support and a roller, with the roller rotatably connected to the support via a shaft. The network cable is wound around the outer wall of the roller. When using this puller, rotating the roller forward retracts the network cable, and rotating it backward releases it.

[0052] When technicians are performing operations such as wiring, installing parts, and transporting the cable pulling tool, it is not necessary to release the network cable to ensure smooth operation. However, the rollers of the cable pulling tool will still rotate spontaneously relative to the support, causing the network cable to be released and spread out, thus hindering the network cable laying work.

[0053] To address the aforementioned technical problems, the present invention provides a cable pulling device by incorporating a limiting component. Specifically, the cable pulling device includes a base, a winding component, and a limiting component. The cable can be wound around the winding component, meaning the winding component can serve as an attachment point for the cable, thereby enabling the cable to be pulled up, which facilitates the storage and transportation of the cable.

[0054] Because the winding assembly is rotatably connected to the base, during the use of the cable pulling device, rotating the winding assembly forward can retract the cable, and rotating it in the reverse direction can release the cable. This facilitates the retraction and release of the cable.

[0055] Because the limiting component is fixedly connected to the base; the limiting component includes a limiting member, which abuts against or separates from the winding assembly; when the limiting member abuts against the winding assembly, the winding assembly is relatively stationary with respect to the base; when the limiting member separates from the winding assembly, the winding assembly can rotate relative to the base. This allows for manual control of the winding assembly.

[0056] The winding assembly can be stationary or rotating relative to the base. Specifically, when the limiting member abuts against the winding assembly, a large pressure is generated between the limiting member and the winding assembly, thus generating a large static friction force. Under the action of this static friction force, the winding assembly remains relatively stationary with respect to the base.

[0057] When the limiting member separates from the winding assembly, there is no pressure between the limiting member and the winding assembly, so there is no static friction between the limiting member and the winding assembly. At this time, the winding assembly can rotate relative to the base.

[0058] When using this cable-pulling tool, the winding assembly will not rotate spontaneously relative to the base when the cable does not need to be released. This means the cable can be manually controlled to be wound or released, facilitating cable laying operations.

[0059] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0060] The following provides a detailed description of the specific structure of the aforementioned wire-pulling device and various possible implementation methods.

[0061] Figure 1 This is a schematic diagram of the structure of a pull wire device 100 provided in this application embodiment when it is in use. Figure 2 for Figure 1 Exploded view of the winding assembly 120 with the wire rope 200 wound around it and the base 110. Figure 3 for Figure 2 A cross-sectional view of the winding assembly 120 formed by cutting it with a plane passing through the axis of the winding bobbin 121. Figure 4 for Figure 1 A schematic diagram of the middle limit component 130.

[0062] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The wire pulling device 100 includes a base 110, a winding assembly 120, and a limiting assembly 130. The winding assembly 120 is rotatably connected to the base 110. The limiting assembly 130 is fixedly connected to the base 110; the limiting assembly 130 includes a limiting member 131, which abuts against or separates from the winding assembly 120; when the limiting member 131 abuts against the winding assembly 120, the winding assembly 120 is relatively stationary relative to the base 110; when the limiting member 131 separates from the winding assembly 120, the winding assembly 120 can rotate relative to the base 110.

[0063] In this embodiment, the cable pulling device 100 includes a base 110, a winding assembly 120, and a limiting assembly 130. The cable 200 can be wound around the winding assembly 120, that is, the winding assembly 120 can serve as an attachment object for the cable 200, thereby enabling the cable 200 to be retracted, which facilitates the storage and transportation of the cable 200.

[0064] Because the winding assembly 120 is rotatably connected to the base 110, during the use of the cable pulling device 100, rotating the winding assembly 120 in the forward direction can retract the cable 200, and rotating the winding assembly 120 in the reverse direction can release the cable 200. Therefore, it is convenient to retract or release the cable 200.

[0065] Because the limiting component 130 is fixedly connected to the base 110; the limiting component 130 includes a limiting member 131, which abuts against or separates from the winding assembly 120; when the limiting member 131 abuts against the winding assembly 120, the winding assembly 120 is relatively stationary with respect to the base 110; when the limiting member 131 separates from the winding assembly 120, the winding assembly 120 can rotate relative to the base 110. This allows for manual control of the winding assembly 120.

[0066] The winding assembly 120 can be stationary or rotate relative to the base 110. Specifically, when the limiting member 131 abuts against the winding assembly 120, a large pressure is generated between the limiting member 131 and the winding assembly 120, resulting in a large static friction force. Under the action of this static friction force, the winding assembly 120 remains relatively stationary with respect to the base 110.

[0067] When the limiting member 131 is separated from the winding assembly 120, there is no pressure between the limiting member 131 and the winding assembly 120, so there is no static friction between the limiting member 131 and the winding assembly 120. At this time, the winding assembly 120 can rotate relative to the base 110.

[0068] When technicians use this cable-pulling tool, the winding assembly 120 will not rotate spontaneously relative to the base 110 when the cable 200 does not need to be released. This means that the cable 200 can be manually retracted or released, facilitating the cable-pulling operation.

[0069] It should be noted that the aforementioned limiting member 131 can be a limiting plate, the surface of which is used to abut or separate from the winding assembly 120. The limiting member 131 can also be other limiting structures with the same function, and this application embodiment does not limit it.

[0070] It should also be noted that the aforementioned cord 200 can be a network cable or a power cable, or a rope or other flexible strip, and this application embodiment does not limit this.

[0071] In a specific wire pulling device 100, the base 110 includes two opposing support frames 111, which can support the winding assembly 120.

[0072] Both support frames 111 are equipped with bearings. The winding assembly 120 is rotatably connected to the support frames 111 via a rotating shaft 140, with two bearings passing through both ends of the shaft 140. A handle 150 is fixedly connected to one end of the rotating shaft 140. The rotating shaft 140 can rotate between the two support frames 111, driving the winding assembly 120 to rotate synchronously. The handle 150 allows technicians to rotate the winding assembly 120 with less effort.

[0073] Both support frames 111 are equipped with anti-slip pads 1111 at their bottoms, and these anti-slip pads 1111 are made of rubber. Because the surface of the rubber anti-slip pads 1111 has good anti-slip properties, it can increase its grip on the ground, thereby reducing the probability of the pull cable device 100 accidentally slipping or moving due to pulling the cable 200, thus improving the stability of the pull cable device 100 during use.

[0074] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The winding assembly 120 includes a winding drum 121 and an end plate 122; the first plate surface 1221 of the end plate 122 is fixedly connected to the end face of the winding drum 121; the area of ​​the first plate surface 1221 is larger than the area of ​​the end face of the winding drum 121, so that the edges of the end plate 122 all protrude from the outer wall of the winding drum 121. The limiting member 131 abuts against or separates from the edge of the first plate surface 1221.

[0075] In this embodiment, the cord 200 can be wound around the outer wall of the winding drum 121, that is, the winding drum 121 can serve as an attachment object for the cord 200, thereby enabling the cord 200 to be wound up, which facilitates the storage and transportation of the cord 200.

[0076] Because the first plate surface 1221 of the end plate 122 is fixedly connected to the end face of the winding drum 121, and the area of ​​the first plate surface 1221 is larger than the area of ​​the end face of the winding drum 121, the edges of the end plate 122 all protrude from the outer wall of the winding drum 121. In this way, the end plate 122 can prevent the rope 200 wound on the winding drum 121 from slipping off the winding drum 121, thereby making the rope 200 wound more stably.

[0077] Because the limiting member 131 abuts against or separates from the edge of the first plate surface 1221, according to the lever principle, compared to other solutions where the limiting member 131 abuts against or separates from the first plate surface 1221, the static friction required to keep the winding assembly 120 stationary when the limiting member 131 abuts against the edge of the first plate surface 1221 is smaller. This, in turn, helps to keep the winding assembly 120 relatively stationary with respect to the base 110, thus improving the structural stability of the wire pulling device 100.

[0078] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 There are two end plates 122, which are fixedly connected to the two end faces of the winding drum 121 in a one-to-one correspondence. The winding drum 121 is a cylindrical tube, and the end plates 122 are circular plates, with the axis of the cylindrical tube passing through the center of the circular plate.

[0079] In this embodiment, there are two end plates 122, which are fixedly connected to the two end faces of the winding drum 121 in a one-to-one correspondence. The two end plates 122 and the outer wall of the winding drum 121 form a winding groove 1611123. Thus, the rope 200 wound on the winding drum 121 is located within the winding groove 1611123. Consequently, both end plates 122 can prevent the rope 200 wound on the winding drum 121 from slipping off, thereby making the winding of the rope 200 more stable.

[0080] Since the winding drum 121 is a cylindrical tube, there are no sharp edges on its outer wall. Therefore, the rope 200 will not experience concentrated stress when wound around the outer wall, thus reducing the probability of rope breakage and allowing for smoother wire pulling. Given that the winding drum 121 is cylindrical, setting the end plate 122 to a circular shape better matches the shape of the winding drum 121.

[0081] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The limiting assembly 130 also includes a support member 132, a threaded seat 133, and a threaded rod 134; the support member 132 is fixedly connected to the base 110. The support member 132 is provided with a connecting hole 1321, and the threaded seat 133 is provided with a threaded hole 1331; the threaded seat 133 is fixedly connected to one end of the connecting hole 1321 so that the threaded hole 1331 and the connecting hole 1321 are coaxially arranged. The threaded rod 134 is inserted into the threaded hole 1331 and the connecting hole 1321, and is threadedly connected to the threaded hole 1331; the limiting member 131 is connected to the first end of the threaded rod 134. When the threaded rod 134 rotates relative to the threaded seat 133, it moves along the axial direction of the threaded hole 1331, so as to drive the limiting member 131 to abut or separate from the winding assembly 120.

[0082] In this embodiment, the threaded connection between the threaded rod 134 and the threaded hole 1331 achieves the effect of moving the limiting member 131 by rotating the threaded rod 134. Specifically, when a technician rotates the second end of the threaded rod 134 forward, the threaded rod 134 can move along the axial direction of the threaded hole 1331, thereby driving the limiting member 131 to move closer to the winding assembly 120 until the limiting member 131 abuts against the winding assembly 120, at which point the winding assembly 120 is stationary relative to the base 110. When a technician rotates the second end of the threaded rod 134 in the reverse direction, the threaded rod 134 can move along the axial direction of the threaded hole 1331, thereby driving the limiting member 131 to move away from the winding assembly 120, until the limiting member 131 separates from the winding assembly 120, at which point the winding assembly 120 can rotate relative to the base 110.

[0083] It should be noted that the second end of the aforementioned threaded rod 134 is fixedly connected to an assist rod 135. Specifically, the second end of the threaded rod 134 is fixedly connected to the middle of the assist rod 135, and the axis of the threaded rod 134 is perpendicular to the axis of the assist rod 135. Technicians can indirectly rotate the threaded rod 134 by rotating the assist rod 135, which is more labor-saving than directly rotating the threaded rod 134. This makes the wire pulling operation more convenient.

[0084] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The edge of one end plate 122 of the winding assembly 120 is disposed between the support member 132 and the limiting member 131. When the threaded rod 134 rotates relative to the threaded seat 133, the limiting member 131 abuts against or separates from the edge of the first plate surface 1221 of the end plate 122.

[0085] In this embodiment, when a technician rotates the second end of the threaded rod 134 forward, the threaded rod 134 can move along the axial direction of the threaded hole 1331, thereby causing the limiting member 131 to move closer to the first plate surface 1221 until the limiting member 131 abuts against the first plate surface 1221. At this time, the winding assembly 120 is stationary relative to the base 110. When a technician rotates the second end of the threaded rod 134 in the reverse direction, the threaded rod 134 can move along the axial direction of the threaded hole 1331, thereby causing the limiting member 131 to move away from the first plate surface 1221 until the limiting member 131 separates from the first plate surface 1221. At this time, the winding assembly 120 can rotate relative to the base 110.

[0086] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The limiting assembly 130 also includes a connector 136, which is disposed on the same side of the support 132 as the limiting member 131, and is fixedly connected to the support 132. The limiting member 131 is rotatably connected to the first end of the threaded rod 134 to prevent the limiting member 131 and the threaded rod 134 from rotating synchronously. A travel groove 1361 is provided on the side of the connector 136 near the limiting member 131; the end of the limiting member 131 near the connector 136 is inserted into the travel groove 1361 so that the end of the limiting member 131 near the connector 136 is always located in the travel groove 1361.

[0087] In this embodiment, the limiting member 131 is rotatably connected to the first end of the threaded rod 134 to prevent the limiting member 131 and the threaded rod 134 from rotating synchronously. Thus, when the threaded rod 134 rotates, it will not carry the limiting member 131 to rotate synchronously. Consequently, when the limiting member 131 contacts the first plate surface 1221 of the end plate 122, it can reduce the wear on the first plate surface 1221 caused by the friction between the two, and also reduce the rotational torque.

[0088] Because the connecting member 136 has a travel groove 1361 on the side near the limiting member 131, and the end of the limiting member 131 near the connecting member 136 is inserted into the travel groove 1361, the end of the limiting member 131 near the connecting member 136 is always located within the travel groove 1361. This further prevents the limiting member 131 from rotating synchronously with the threaded rod 134. Furthermore, when the limiting member 131 contacts the first plate surface 1221 of the end plate 122, it can further reduce the wear on the first plate surface 1221 caused by the friction between the two, and at the same time, it can further reduce the rotational torque.

[0089] Specifically, a limiting block 1311 is provided at one end of the limiting member 131 near the connecting member 136. The limiting block 1311 is inserted into the stroke groove 1361, thereby preventing the limiting member 131 from rotating synchronously with the threaded rod 134.

[0090] It should be noted that the aforementioned support member 132 is a support plate, and the aforementioned connector 136 is a connecting plate. The surfaces of the support plate and the connecting plate are perpendicular. A gripping member 137 is fixedly connected to the side of the support plate opposite to the limiting member 131. When a technician needs to move the pull cable device 100, he / she can grasp the gripping member 137 to lift the pull cable device 100, thus facilitating the movement of the pull cable device 100.

[0091] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The cable pulling device 100 includes a cable clamping assembly 160. The cable clamping assembly 160 includes a connecting seat 161, a clamping plate 162, and a clamping post 163. The connecting seat 161 is fixedly connected to the limiting assembly 130, and the side of the clamping plate 162 is fixedly connected to the connecting seat 161. The space between the first end of the clamping post 163 and the clamping surface 1621 of the clamping plate 162 is used for threading the cable 200; the first end of the clamping post 163 abuts against or separates from the clamping surface 1621.

[0092] In this embodiment, the wire clamping assembly 160 includes a connecting seat 161 and a wire clamping plate 162; the connecting seat 161 is fixedly connected to the limiting assembly 130, and the side of the wire clamping plate 162 is fixedly connected to the connecting seat 161. In this way, the wire clamping plate 162, the connecting seat 161, and the limiting assembly 130 are connected as a whole, thereby enhancing the overall integrity of the wire pulling device 100.

[0093] The space between the first end of the clamping post 163 and the clamping surface 1621 of the clamping plate 162 is used for threading the wire 200. This allows the wire 200 to be threaded through the space between the first end of the clamping post 163 and the clamping surface 1621 of the clamping plate 162. Specifically, when retracting or releasing the wire 200, the wire 200 must pass between the first end of the clamping post 163 and the clamping surface 1621 of the clamping plate 162.

[0094] Because the first end of the clamping post 163 abuts against or separates from the clamping surface 1621. Specifically, when the first end of the clamping post 163 abuts against the clamping surface 1621, the rope 200 is clamped between the first end of the clamping post 163 and the clamping surface 1621, and the rope 200 cannot be retracted or unfolded at this time. When the first end of the clamping post 163 separates from the clamping surface 1621, the rope 200 can move freely, and the rope 200 can be retracted or unfolded at this time. The clamping assembly 160 can temporarily fix the rope 200, and thus the retraction or unfolding of the rope 200 can be manually controlled, thereby further facilitating the pulling work.

[0095] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The wire clamping assembly 160 also includes a first support plate 164, a second support plate 165, a third support plate 166, an elastic element 167, a snap-fit ​​rod 168, and a snap-fit ​​assembly 169.

[0096] The first support plate 164 and the second support plate 165 are arranged opposite to each other. One side of the first support plate 164 and one side of the second support plate 165 are fixedly connected to the wire clamping surface 1621. The side of the first support plate 164 away from the wire clamping surface 1621 and the side of the second support plate 165 away from the wire clamping surface 1621 are fixedly connected to the same surface of the third support plate 166. The first support plate 164, the second support plate 165 and the third support plate 166 enclose and form a wire threading channel 1610. The third support plate 166 is provided with a through hole 1661.

[0097] The second end of the clamping post 163 is fixedly connected to the middle of the side of the clamping rod 168. The clamping post 163 is provided with a limiting protrusion 1631, which protrudes from the cylindrical surface of the clamping post 163. The clamping post 163 passes through the through hole 1661, and the limiting protrusion 1631 is located in the wire passage 1610.

[0098] The elastic element 167 is located in the wire passage 1610 and sleeved on the wire clamping post 163; the first end of the elastic element 167 is connected to the limiting protrusion 1631, and the second end of the elastic element 167 is connected to the third support plate 166.

[0099] The locking rod 168 is connected to or separated from the locking assembly 169; when the locking rod 168 is connected to the locking assembly 169, the elastic element 167 is compressed, and the first end of the wire clamping post 163 is separated from the wire clamping surface 1621; when the locking rod 168 is separated from the locking assembly 169, the elastic element 167 is extended, and the first end of the wire clamping post 163 abuts against the wire clamping surface 1621.

[0100] In this embodiment, the elastic force of the elastic element 167 is used to connect or separate the first end of the clamping post 163 from the clamping surface 1621. Specifically, when a technician lifts the latching rod 168 and connects it to the latching assembly 169, the first end of the clamping post 163 separates from the clamping surface 1621, at which point the cable 200 can be retracted or released. Simultaneously, the limiting protrusion 1631 compresses the elastic element 167. When the technician lifts the latching rod 168 and separates it from the latching assembly 169, the elastic element 167 extends freely and, through the limiting protrusion 1631, causes the first end of the clamping post 163 to abut against the clamping surface 1621. At this point, the cable 200 is clamped between the first end of the clamping post 163 and the clamping surface 1621, and the cable 200 cannot be retracted or unfolded.

[0101] It should be noted that the aforementioned limiting protrusion 1631 can be an annular protrusion, which extends circumferentially along the clamping post 163. In addition, the limiting protrusion 1631 can also be other shapes, which are not limited in this embodiment.

[0102] It should also be noted that the above-mentioned elastic element 167 can be a spring or a rubber sleeve, or other types of elastic element 167, and the embodiments of this application do not limit it.

[0103] It should also be noted that the aforementioned clamping post 163 can be a cylinder or a prism, and this embodiment of the application does not limit this. However, the cross-section of the clamping post 163 needs to be adapted to the cross-section of the through hole 1661 on the third support plate 166.

[0104] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The snap-fit ​​assembly 169 includes two snap-fit ​​plates 1691 arranged in parallel and opposite directions. The sides of the two snap-fit ​​plates 1691 are fixedly connected to the side of the third support plate 166 facing away from the clamping surface 1621. Each of the two snap-fit ​​plates 1691 has a snap-fit ​​groove 16911 on the side facing away from the clamping surface 1621. When the snap-fit ​​rod 168 is connected to the snap-fit ​​assembly 169, the two ends of the snap-fit ​​rod 168 are embedded in the two snap-fit ​​grooves 16911 respectively. When the snap-fit ​​rod 168 is separated from the snap-fit ​​assembly 169, the snap-fit ​​rod 168 abuts against the third support plate 166.

[0105] In this embodiment, the snap-fit ​​assembly 169 includes two snap-fit ​​plates 1691 arranged in parallel and opposite directions. The sides of both snap-fit ​​plates 1691 are fixedly connected to the side of the third support plate 166 facing away from the clamping surface 1621. Each of the two snap-fit ​​plates 1691 has a snap-fit ​​groove 16911 on the side facing away from the clamping surface 1621. Thus, the bottom of each of the two snap-fit ​​grooves 16911 is at a certain distance from the side of the third support plate 166 facing away from the clamping surface 1621.

[0106] When the locking rod 168 is connected to the locking assembly 169, its two ends are embedded in the two locking slots 16911 respectively. This prevents the locking rod 168 from slipping off the two locking plates 1691, making the connection between the locking rod 168 and the locking assembly 169 more stable. Consequently, a certain distance is maintained between the first end of the wire clamping post 163 and the wire clamping surface 1621, making it easier to reel in or release the wire 200.

[0107] When the locking rod 168 separates from the locking assembly 169, the locking rod 168 abuts against the third support plate 166. The elastic element 167 extends freely and, through the limiting protrusion 1631, drives the first end of the clamping post 163 to abut against the clamping surface 1621. At this time, the rope 200 is clamped between the first end of the clamping post 163 and the clamping surface 1621. The rope 200 cannot be retracted or unfolded, which helps to keep the pulling device 100 stable.

[0108] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 Both the first end of the clamping post 163 and the clamping surface 1621 are provided with wire grooves 1611. When the first end of the clamping post 163 abuts against the clamping surface 1621, the two wire grooves 1611 surround to form a wire hole, which is used to thread the wire rope 200.

[0109] In this way, when the cord 200 is clamped between the first end of the clamping post 163 and the clamping surface 1621, the cord 200 is located within the thread hole. This ensures that the cord 200 will not be damaged, thus guaranteeing its normal use.

[0110] It should be noted that the cross-section of the threading hole is slightly smaller than the cross-section of the cord 200 so that the cord 200 is in an interference fit when it is clamped in the threading hole.

[0111] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0112] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0113] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something,” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “above something” or “on top of something,” but also “on something” or “on top of something” without an intermediate feature or layer therebetween, i.e., directly on something.

[0114] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations rotated 90° or be in other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.
