[0014] In some embodiments, the slider is configured as a frustum structure, and the diameter of the slider gradually decreases from the end closer to the support member to the end farther away from the support member.

Obviously, the described embodiments are only some embodiments of this application, and 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.

[0038] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0040] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0041] Please refer to the following: Figure 1 and Figure 2This application provides a sleeve wire removal device 1, including a sleeve 11, a transmission assembly 12, a driving component (not shown in the figure), and a claw assembly 13. The sleeve 11 has a through hole 111 extending through both ends of the sleeve 11. The transmission assembly 12 is at least partially disposed within the through hole 111 and configured to rotate relative to the sleeve 11. The transmission assembly 12 has an input end 121 and an output end 122, located at opposite ends of the sleeve 11. The driving component is connected to the input end 121. The claw assembly 13 includes a lead screw 131, a support member 132, and multiple movable plates 133. The lead screw 131 is connected to the output end 122. The support member 132 is sleeved on the lead screw 131. The multiple movable plates 133 are rotatably connected to the support member 132, and the rotation axes of the multiple movable plates 133 are perpendicular to the rotation axis of the lead screw 131. The drive unit drives the lead screw 131 to rotate through the transmission assembly 12. Multiple movable plates 133 are configured to rotate from a first position to a second position when the lead screw 131 rotates. When the multiple movable plates 133 are in the second position, they engage with the inner wall of the wire guard. The multiple movable plates 133 rotate around the lead screw 131 to drive the wire guard to rotate.

[0042] It should be noted that although the bearing component 132 is sleeved on the lead screw 131, there is no direct connection between the bearing component 132 and the lead screw 131. In other words, there is no direct transmission relationship between the lead screw 131 and the bearing component 132.

[0043] The number of activity boards 133 can be three, or any other number, which is not limited here.

[0044] In this application, the claw assembly 13 is at least partially inserted into the wire guard. When the drive unit outputs power to the input end 121, the output end 122 is rotated through the transmission assembly 12. The rotation of the output end 122 causes the lead screw 131 to rotate synchronously. At this time, the bearing member 132 does not follow the lead screw 131 in rotating around its rotation axis, thereby restricting the multiple movable plates 133 from rotating around the lead screw 131. However, at this time, the movable plate 133 is configured to rotate around its own rotation axis, and the movable plate 133 rotates from the first position to the second position. When the movable plate 133 is in the first position, the movable plate 133 is closer to the lead screw 131, and when the movable plate 133 is in the second position, the movable plate 133 is further away from the lead screw 131. That is to say, the movable plate 133 gradually opens relative to the lead screw 131 during the process of rotating from the first position to the second position. When the movable plate 133 is in the second position, it contacts and locks against the inner wall of the wire guard, preventing it from opening further. It should be noted that when multiple movable plates 133 are in the second position, the rotation axis of the lead screw 131 approximately coincides with the central axis of the wire guard.

[0045] As the lead screw 131 continues to rotate, multiple movable plates 133 rotate synchronously around the axis of rotation of the lead screw 131, and the bearing component 132 is also driven by the movable plates 133 to rotate synchronously around the axis of rotation of the lead screw 131. Because the movable plates 133 are locked to the wire protector, the wire protector rotates with the movable plates 133 as the multiple movable plates 133 rotate around the axis of rotation of the lead screw 131, thereby removing the wire protector from the end of the sleeve.

[0046] This application uses a drive component to drive the transmission assembly 12 to rotate the lead screw 131. When the lead screw 131 rotates, multiple movable plates 133 rotate from the first position to the second position and then abut against and lock against the inner wall of the wire protector. As the lead screw 131 continues to rotate, the multiple movable plates 133 are configured to rotate synchronously with the lead screw 131 along the circumference of the lead screw 131, thereby driving the wire protector to rotate and remove the wire protector from the end of the sleeve. Compared with the prior art of manual disassembly using a traditional wrench, this method can improve the disassembly efficiency of the wire protector, while ensuring that the wire protector is subjected to uniform force and protecting the threads of the wire protector, thereby protecting the threads of the sleeve.

[0047] Please see Figure 1 In some embodiments, the chuck assembly 13 further includes a slider 134, which is sleeved on and threadedly connected to the lead screw 131. The slider 134 is located on the side of the carrier 132 opposite to the output end 122, and abuts against multiple movable plates 133. The slider 134 is configured to move away from the carrier 132 along the axis of the lead screw 131 when the lead screw 131 rotates, thereby pushing the multiple movable plates 133 to rotate from a first position to a second position.

[0048] In this embodiment, the claw assembly 13 is at least partially inserted into the wire guard. The drive unit drives the output end 122 to rotate via the transmission assembly 12. The rotation of the output end 122 drives the lead screw 131 to rotate synchronously. Since there is no direct connection between the bearing member 132 and the lead screw 131, the bearing member 132 does not follow the lead screw 131 to rotate around the rotation axis of the lead screw 131, thereby restricting the multiple movable plates 133 from rotating around the rotation axis of the lead screw 131. However, the slider 134 is connected to the lead screw 131 by a thread. At this time, it is only necessary to restrict the slider 134 from rotating circumferentially along the lead screw 131, so that the slider 134 can move relative to the lead screw 131 along the axial direction of the lead screw 131 when the lead screw 131 rotates. Since the multiple movable plates 133 abut against the slider 134, during the movement of the slider 134, the slider 134 gradually opens up the multiple movable plates 133, that is, pushes the multiple movable plates 133 to rotate from the first position to the second position along the rotation axis of the movable plate 133 itself.

[0049] After the multiple movable plates 133 are in the second position, the multiple movable plates 133 contact and jam with the inner wall of the wire protector, causing the slider 134 to be unable to continue moving relative to the lead screw 131 along the axial direction of the lead screw 131 to further open the movable plates 133. That is, at this time, the slider 134 is jammed relative to the lead screw 131 in the axial direction of the lead screw 131. The slider 134 can only follow the lead screw 131 to rotate synchronously along the circumference of the lead screw 131. At the same time, the multiple movable plates 133 are configured to follow the lead screw 131 to rotate synchronously along the circumference of the lead screw 131, thereby driving the wire protector to rotate, so as to remove the wire protector from the end of the sleeve.

[0050] In some embodiments, the side of the slider 134 is provided with multiple limiting grooves (not shown in the figure), and multiple movable plates 133 are embedded in the multiple limiting grooves one by one.

[0051] Since multiple movable plates 133 are embedded one-to-one in the multiple limiting grooves on the side of the slider 134, the multiple movable plates 133 and the slider 134 can only rotate synchronously. Since the multiple movable plates 133 are connected to the support member 132, the multiple movable plates 133 and the support member 132 can only rotate synchronously. In other words, the support member 132, the multiple movable plates 133, and the slider 134 can only rotate synchronously. It should be noted that "the support member 132, the multiple movable plates 133, and the slider 134 can only rotate synchronously" means that the support member 132, the multiple movable plates 133, and the slider 134 either do not rotate or rotate together synchronously.

[0052] In this embodiment, the claw assembly 13 is at least partially inserted into the wire guard. The drive unit drives the output end 122 to rotate via the transmission assembly 12. The rotation of the output end 122 drives the lead screw 131 to rotate synchronously. At this time, the bearing member 132 can be located outside the wire guard. Applying an external force to the bearing member 132 to prevent it from rotating will also prevent the slider 134 from rotating. Since the slider 134 and the lead screw 131 are connected by a thread, the slider 134 can move relative to the lead screw 131 along the axial direction of the lead screw 131, thereby gradually opening up the multiple movable plates 133 and pushing the multiple movable plates 133 to rotate from the first position to the second position along their own rotation axis.

[0053] After the multiple movable plates 133 are in the second position, they contact and jam against the inner wall of the wire protector, preventing the slider 134 from moving further relative to the lead screw 131 along its axial direction to further open the movable plates 133. In other words, the slider 134 is jammed relative to the lead screw 131 in the axial direction. Removing the external force applied to the support member 132 allows the slider 134 to rotate. Since the slider 134 is jammed relative to the lead screw 131 in the axial direction, it can rotate synchronously with the lead screw 131 along its circumference. This causes the multiple movable members and the support member 132 to rotate synchronously with the lead screw 131 along its circumference. The rotation of the multiple movable members with the lead screw 131 drives the wire protector to rotate, thereby removing the wire protector from the end of the sleeve.

[0054] In some embodiments, the slider 134 is configured as a frustum structure, and the diameter of the slider 134 gradually decreases from the end closer to the support member 132 to the end farther away from the support member 132.

[0055] In this embodiment, when the movable plate 133 is in the first position, the slider 134 approaches the support member 132, and the contact position between the movable plate 133 and the limiting groove is closer to the end of the support member 132 with a smaller diameter. As the movable plate 133 rotates from the first position to the second position, the slider 134 gradually moves away from the support member 132, and the contact position between the movable plate 133 and the limiting groove moves towards the end of the support member 132 with a larger diameter. When the movable plate 133 is in the second position, the contact position between the movable plate 133 and the limiting groove is closer to the end of the support member 132 with a larger diameter.

[0056] In some embodiments, the movable plate 133 has a snap-fit ​​surface (not shown) configured to snap against the inner wall of the wire guard when the movable plate 133 is in the second position.

[0057] In this embodiment, the claw assembly 13 is at least partially inserted into the wire guard. When the movable plate 133 is in the second position, the engaging surface of the movable plate 133 contacts the inner wall of the wire guard and forms a surface contact. In some examples, the surface contact between the engaging surface and the inner wall increases the contact area between the engaging surface and the inner wall of the wire guard, thereby increasing the friction between the engaging surface and the inner wall of the wire guard, enabling the engaging surface to engage with the wire guard, and driving the wire guard to rotate through friction. In other examples, a groove can be provided on the inner wall of the wire guard, and a protrusion can be provided on the engaging surface. When the engaging surface contacts the inner wall of the wire guard, the protrusion is embedded in the groove, and the protrusion pushes the groove and the friction formed between the engaging surface and the inner wall of the wire guard to jointly drive the wire guard to rotate. Of course, other engaging designs can be made between the engaging surface and the inner wall of the wire guard, which are not limited here.

[0058] Please refer to the following: Figure 1 and Figure 3In some embodiments, the claw assembly 13 further includes a connector 135, one end of which is connected to the end of the lead screw 131, and the other end of which is provided with a slot that engages with the output end 122.

[0059] The slot is located at the center of one end of the connector 135, and the connector 135 is connected to the center of the other end of the connector 135, so that when the output end 122 is engaged with the slot at one end of the connector 135 and the lead screw 131 is connected to the other end of the connector 135, the rotation axis of the output end 122 and the rotation axis of the lead screw 131 are approximately coincident.

[0060] In some embodiments, the transmission assembly 12 is configured such that the rotational speed of the output terminal 122 is less than the rotational speed of the input terminal 121 when driven by the drive element.

[0061] In this embodiment, after the driving component outputs power to the input end 121 to drive the input end 121 to rotate, it drives the output end 122 to rotate through the transmission component. The rotation speed of the output end 122 is less than the rotation speed of the input end 121, so as to increase the output torque. After the movable plate 133 is engaged with the inner wall of the wire protector, the difficulty of removing the wire protector can be reduced.

[0062] Please refer to the following: Figure 1 and Figure 3 In some embodiments, a gear ring 112 is provided on the inner wall of the sleeve 11 surrounding the through hole 111. The transmission assembly 12 includes a first gear sleeve 123 and an input component 124. The first gear sleeve 123 includes a first planetary carrier 1231 and a plurality of first planetary gears 1232. One end of the first planetary carrier 1231 is configured as an output end 122, and the plurality of first planetary gears 1232 are rotatably disposed on the first planetary carrier 1231 and mesh with the gear ring 112. One end of the input component 124 is configured as an input end 121, and the other end is provided with a sun gear 125, which is connected to the plurality of first planetary gears 1232 in a transmission manner.

[0063] In this embodiment, a gear ring 112 is provided on the inner wall of the sleeve 11, making the sleeve 11 form a structure similar to an internal gear. When the first gear sleeve 123 is disposed in the through hole 111, the plurality of first planetary gears 1232 of the first gear sleeve 123 mesh with the gear ring 112, and the first planetary gears 1232 can move circumferentially along the gear ring 112 while rotating along their own rotation axis, so as to drive the first planetary carrier 1231 to rotate, thereby realizing the rotation of the output end 122. It should be noted that the rotation axis of the first planetary carrier 1231 is approximately coincident with the central axis of the through hole 111, and the rotation axis of the output end 122 is approximately coincident with the rotation axis of the first planetary carrier 1231.

[0064] To drive the rotation of multiple first planetary gears 1232, this embodiment provides a sun gear 125 at the end of the input component 124 opposite to the input end 121. The sun gear 125 is connected to the multiple first planetary gears 1232. When the driving component supplies power to the input end 121, causing the input end 121 to rotate, the sun gear 125 rotates synchronously with the input end 121. The rotation of the sun gear 125 drives the multiple first planetary gears 1232 to rotate on their own axis and revolve around a central point. The revolve of the multiple first planetary gears 1232 drives the first planet carrier 1231 to rotate, thereby realizing the rotation of the output end 122. It should be noted that the connection between the sun gear 125 and the multiple first planetary gears 1232 can be either direct meshing (i.e., the sun gear 125 directly drives the multiple first planetary gears 1232) or indirect meshing (i.e., the sun gear 125 indirectly drives the multiple first planetary gears 1232). No limitation is made here.

[0065] When the sun gear 125 directly meshes with the multiple first planetary gears 1232, the transmission assembly 12 forms a single-stage reducer. Specifically, the sun gear 125 is inserted from the end of the first planetary carrier 1231 away from the output end 122, and meshes with the multiple first planetary gears 1232 simultaneously, with the rotation axis of the sun gear 125 approximately coinciding with the rotation axis of the first planetary carrier 1231. When the drive unit drives the input end 121 to rotate, it drives the sun gear 125 to rotate synchronously, and the rotation of the sun gear 125 directly drives the multiple first planetary gears 1232 to rotate on their own axis and revolve around the sun.

[0066] When the sun gear 125 indirectly meshes with multiple first planetary gears 1232, the transmission assembly 12 can form a multi-stage reducer, such as a two-stage or three-stage reducer, without limitation here. For example, the transmission assembly 12 forms a two-stage reducer as described below, which will not be repeated here.

[0067] Please refer to the following: Figure 1 and Figure 3 In some embodiments, the transmission assembly 12 further includes a second gear sleeve 126 and a transmission gear 127. The second gear sleeve 126 includes a second planetary carrier 1261 and a plurality of second planetary gears 1262, which are rotatably disposed on the second planetary carrier 1261. The plurality of second planetary gears 1262 mesh with a ring gear 112 and a sun gear 125. The transmission gear 127 is connected to the second planetary carrier 1261 and meshes with a plurality of first planetary gears 1232.

[0068] In this embodiment, the transmission gear 127 is connected to one end of the second planetary carrier 1261, and the rotation axis of the transmission gear 127 is approximately coincident with the rotation axis of the second planetary carrier 1261. The transmission gear 127 is inserted from the end of the first planetary carrier 1231 away from the output end 122 and meshes with a plurality of first planetary gears 1232. The sun gear 125 is inserted from the end of the second planetary carrier 1261 away from the transmission gear 127 and meshes with a plurality of second planetary gears 1262 simultaneously. At the same time, the plurality of second planetary gears 1262 mesh with the ring gear 112.

[0069] When the drive input terminal 121 rotates, it drives the sun gear 125 to rotate. The rotation of the sun gear 125 drives multiple second planetary gears 1262 to rotate on their own axis and revolve around the sun. The revolve of the multiple second planetary gears 1262 drives the second planetary carrier 1261 to rotate. The rotation of the second planetary carrier 1261 drives the transmission gear 127 to rotate. The rotation of the transmission gear 127 drives multiple first planetary gears 1232 to rotate on their own axis and revolve around the sun. The revolve of the multiple first planetary gears 1232 drives the first planetary carrier 1231 to rotate. The rotation of the first planetary carrier 1231 drives the output terminal 122 to rotate.

[0070] In this embodiment, a two-stage reducer is formed by the sun gear 125, the second gear sleeve 126, the transmission gear 127, and the first gear sleeve 123 at one end of the input component 124, which can further improve the output torque at the output end 122. The number of both the first planetary gear 1232 and the second planetary gear 1262 can be four, or other numbers are not limited here.

[0071] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the inner wall of the sleeve 11 forming the through hole 111 is provided with a first step 113 and a second step 114. The first step 113 and the second step 114 are respectively located at both ends of the sleeve 11. The gear ring 112 is located between the first step 113 and the second step 114. The first planetary carrier 1231 abuts against the first step 113, and the input member 124 abuts against the second step 114.

[0072] When the first planetary carrier 1231 abuts against the first step 113, it can be positioned in the axial direction of the through hole 111. When the input component 124 abuts against the second step 114, it can be positioned in the axial direction of the through hole 111. Since the second gear sleeve 126 is approximately located between the input component 124 and the first planetary carrier 1231, and the transmission relationship between the second gear sleeve 126, the input component 124, and the first planetary carrier 1231 is determined, after the first planetary carrier 1231 and the input component 124 are positioned in the axial direction of the through hole 111, the position of the second gear sleeve 126 in the axial direction of the through hole 111 is then determined.

[0073] In this embodiment, the installation sequence of the transmission assembly 12 is as follows: First, the first gear sleeve 123 is installed from the first end of the sleeve 11. After the first planetary carrier 1231 abuts against the first step 113, the second gear sleeve 126 connecting the transmission gear 127 is installed from the second end of the sleeve 11. After the transmission gear 127 meshes with multiple first planetary gears 1232 simultaneously, the input component 124 is installed from the second end of the sleeve 11.
