[0046] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions of the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0048] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0049] In the related technology, the fixing device includes three layers of anti-wear sleeves: inner, middle and outer. The outer anti-wear sleeve and the middle anti-wear sleeve are arranged to form an outer anti-wear cavity, and the middle anti-wear sleeve and the inner anti-wear sleeve are arranged to form an inner anti-wear cavity. Cables of different diameters are placed in the inner anti-wear cavity and the outer anti-wear cavity respectively to achieve layered and separated arrangement of the cables, thereby avoiding friction damage between the cables and preventing collision and wear between the cables and the outside.

[0050] However, in the actual installation process, each anti-wear sleeve is manually lifted so that the cable is placed between two adjacent anti-wear sleeves, and then the relative position of each anti-wear sleeve is adjusted one by one so that the fixing holes between the outer anti-wear sleeve, the middle anti-wear sleeve and the inner anti-wear sleeve are aligned one by one, and the fasteners are inserted into the fixing holes under manual lifting, and the fasteners are manually tightened by means of adapter nuts. This results in a long manual lifting time, is very laborious, and is inconvenient to operate, resulting in low installation efficiency.

[0051] The embodiment of the present application provides a cable protection device, including a limiting structure and at least one adjustment mechanism. At least three limiting mechanisms are arranged in sequence from the inside to the outside, so as to enclose a limiting area for placing cables between two adjacent limiting mechanisms; a fixing assembly is arranged on the limiting mechanism located inside, so as to rotatably set a driving member on the fixing assembly, and at least two supporting members are arranged on the driving member; in this way, when the two supporting members are driven away from each other by the driving member, that is, when both supporting members extend outward relative to the internal limiting mechanism, the remaining limiting mechanisms can be inserted into the supporting members one by one, and the cable can be placed between the two adjacent limiting mechanisms at the same time; thus, the supporting members provide supporting force for each limiting mechanism, so that the relative position of each limiting mechanism can be maintained under the action of the supporting members, and the pre-fixation of the protection device and the cable can be realized, so as to avoid the need to manually adjust the relative position of each limiting mechanism one by one in the state of manually lifting each limiting mechanism, so as to connect and fix each limiting mechanism through fasteners. The embodiment of the present application can provide convenience for the operation of fixing the protection device and the cable as a whole, thereby improving the working efficiency.

[0052] The technical solution of the present application is described in detail below with reference to the accompanying drawings using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0053] like Figures 1 to 3 As shown, an embodiment of the present application provides a cable protection device, including a limiting structure 100 and at least one adjustment mechanism 200 .

[0054] The limiting structure 100 includes at least three limiting mechanisms 110 arranged in sequence from the inside to the outside. Two adjacent limiting mechanisms 110 together form a limiting area 120, and the limiting area 120 is used to place cables.

[0055] The adjusting mechanism 200 includes a fixing component 210 and an adjusting component 220. The fixing component 210 is arranged on the internal limiting mechanism 110. The adjusting component 220 includes a driving member 221 and at least two supporting members 222. The driving member 221 is rotatably arranged on the fixing component 210. One end of the supporting member 222 is connected to the driving member 221. The driving member 221 drives the two supporting members 222 to move closer to or away from each other. Each limiting mechanism 110 is inserted into the supporting member 222 in turn through the other end of the supporting member 222.

[0056] In the embodiment of the present application, at least three limiting mechanisms 110 are coaxially sleeved and arranged in sequence at intervals, so that two adjacent limiting mechanisms 110 together enclose a limiting area 120, and the limiting area 120 is used to accommodate the cable. The limiting mechanisms 110 can be made of materials such as plastic, nylon or rubber, so that each limiting mechanism 110 has good wear resistance and flexibility, and is light in weight, so as not to cause a load on the cable, thereby avoiding dragging or scratching the cable skin.

[0057] It is understandable that the spacing distance between two adjacent limiting mechanisms 110 determines the maximum cable diameter that the limiting area 120 can accommodate. The limiting mechanisms 110 can be set with different spacing distances to place cables of different diameters in different limiting areas 120. The specific setting of the limiting area 120 can be adaptively set according to the actual use scenario, and the embodiment of the present application does not impose specific restrictions on this. In this way, the layered arrangement of cables can be achieved to avoid friction damage between cables and prevent collision and wear between cables and external devices.

[0058] In the specific setting, the internal limiting mechanism 110, that is, the central limiting mechanism 110, is provided with a fixing component 210, and a driving member 221 is rotatably provided on the fixing component 210. Exemplarily, the driving member 221 can be a structure such as a motor, by relatively arranging at least two supporting members 222 in the radial direction of the motor output shaft; in this way, when the motor output shaft rotates, the two supporting members 222 move away from each other, or when the motor output shaft rotates in the opposite direction, the two supporting members 222 move closer to each other.

[0059] In a specific implementation, a plurality of cables are placed on the periphery of the central limiting mechanism 110, and are to be placed in layers in the limiting area 120 surrounded by two adjacent limiting mechanisms 110 from the inside to the outside. It should be noted that the central limiting mechanism 110 may be provided with a detachable connecting member such as a connecting rope, and the central limiting mechanism 110 is connected to the cable or other positioning structural member through the connecting rope to achieve the pre-positioning of the central limiting mechanism 110; in some embodiments, the friction between the cable and the central limiting mechanism 110 can also provide a clamping effect for the central limiting mechanism 110 to achieve the pre-positioning of the central limiting mechanism 110.

[0060] When used in the embodiment of the present application, the driving member 221 is rotated so that the two support members 222 are extended outward relative to the central limiting mechanism 110, that is, when the two support members 222 are away from each other, the remaining limiting mechanisms 110 are inserted into the support member 222 one by one through the end of the support member 222 away from the driving member 221, and a cable is placed between two adjacent limiting mechanisms 110.

[0061] In the embodiment of the present application, the support member 222 provides support force for each limiting mechanism 110, so that the relative position of each limiting mechanism 110 can be maintained under the action of the support member 222, and the protective device and the cable are pre-fixed; each limiting mechanism 110 can be manually pushed from the outside to the inside along the support member 222, so that each limiting mechanism 110 clamps the cable in the limiting area 120. In addition, illustratively, each limiting mechanism 110 is provided with a one-to-one corresponding fastening hole, and fasteners such as bolts are directly inserted into the fastening hole to clamp each limiting mechanism 110 and the cable. It can be understood that the pre-positioning of the central limiting mechanism 110 can be released after each limiting mechanism 110 and the cable are clamped and fixed as a whole.

[0062] In this way, it is possible to avoid manually adjusting the relative positions of the limiting mechanisms 110 one by one while manually lifting each limiting mechanism 110, so as to connect and fix each limiting mechanism 110 through fasteners. The embodiment of the present application can facilitate the operation of fixing the protective device and the cable as a whole, thereby improving the operation efficiency.

[0063] In some embodiments, the adjustment assembly 220 further includes at least two stoppers 223 , and the stoppers 223 are correspondingly connected to the support members 222 .

[0064] The driving member 221 is configured to, when rotating relative to the fixing assembly 210 , sequentially drive the supporting member 222 and the stopping member 223 to move toward the limiting mechanism 110 located inside, so as to clamp the cable in the limiting area 120 .

[0065] In the embodiments of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, each limiting mechanism 110 is inserted into the support member 222 one by one through the end of the support member 222 away from the driving member 221, and when all cables are placed in the limiting area 120, a stopper 223 is provided on one end of the limiting mechanism 110 located at the outermost end of the support member 222.

[0066] In a specific configuration, the end of the support member 222 extending out of the external limiting mechanism 110 has a stopper 2222, and the stopper 223 is correspondingly connected to the stopper 2222. Exemplarily, when the stopper 223 is a screw or a bolt, the stopper 2222 is a matching screw hole; or, when the stopper 223 is a pin shaft, the stopper 2222 is a matching pin shaft hole.

[0067] During actual use, the driving member 221 is rotated in the opposite direction so that the two support members 222 are both retracted inwardly relative to the central limiting mechanism 110, that is, when the two support members 222 are close to each other, the stop member 223 abuts against the outermost limiting mechanism 110 and moves toward the central limiting mechanism 110 along the support members 222; in this way, each limiting mechanism 110 moves from the outside to the inside along the support members 222 under the pushing action of the stop member 223, so that each limiting mechanism 110 clamps the cable in the limiting area 120, thereby avoiding manual pushing of each limiting mechanism 110 to move inwardly to clamp the cable, thereby improving the ease of use of the embodiment of the present application.

[0068] It should be noted that in the embodiment of the present application, the number of support members 222 is two, and the number of stop members 223 is also two. The specific structure and the number of stop members 223 used in the embodiment of the present application are not specifically limited, as long as the stop members 223 are connected one-to-one with the support members 222.

[0069] In some embodiments, the fixing assembly 210 includes a fixing base 211 and at least two fixing members 212 disposed on the fixing base 211 , one end of the fixing member 212 away from the fixing base 211 is connected to the limiting mechanism 110 located inside, and the driving member 221 is rotatably disposed on the fixing base 211 .

[0070] In the embodiments of the present application, Figures 1 to 3 As shown, exemplarily, the fixing seat 211 is a hollow structure, and at least two fixing members 212 are connected to the outer wall of the fixing seat 211 by welding or bonding, and the end of the fixing member 212 facing away from the fixing seat 211 can be correspondingly plugged in or abutted against the central limiting mechanism 110 by interference fit, so as to ensure that the fixing seat 211 can be firmly connected to the limiting mechanism 110.

[0071] In the specific configuration, a rotation shaft hole is provided on the fixing seat 211, and the driving member 221 is correspondingly connected in the rotation shaft hole so that the driving member 221 can rotate relative to the rotation shaft hole. By providing the fixing seat 211, the driving member 221 can be easily installed.

[0072] It should be noted that the embodiment of the present application does not impose too many restrictions on the specific structure of the fixing base 211 and the fixing member 212. For example, the fixing base 211 can be a circular or rectangular structure, and the fixing member 212 can be a cylindrical or prismatic structure. The specific structure can be adaptively set according to the actual usage scenario.

[0073] In some embodiments, the adjustment component 220 also includes at least two transmission members 224, the transmission member 224 includes a transmission part 2241 and a connecting part 2242 arranged at one end of the transmission part 2241, the transmission part 2241 is connected to the driving member 221, and the end of the connecting part 2242 away from the transmission part 2241 is rotatably inserted into the limiting mechanism 110 located inside, the connecting part 2242 is arranged corresponding to the support member 222, and one end of the support member 222 is rotatably connected to the connecting part 2242.

[0074] The transmission part 2241 is configured to drive the connection parts 2242 to rotate under the drive of the driving member 221 so that the two supporting members 222 are closer to or farther away from each other, and each limiting mechanism 110 is inserted into the supporting member 222 through the other end of the supporting member 222 in turn.

[0075] In the embodiments of the present application, Figure 2 and Figure 3 As shown, a transmission member 224 is provided on the driving member 221, and the number of the transmission members 224 corresponds to the supporting member 222 one by one; in the specific setting, the transmission member 224 includes a transmission part 2241 and a connecting part 2242. For example, the driving member 221 can be a motor, the transmission part 2241 can be a transmission shaft, and the transmission shaft is connected to the output shaft of the motor; the connecting part 2242 can be a threaded sleeve, one end of the threaded sleeve is connected to the transmission shaft, and a plug-in hole is correspondingly provided on the central limiting mechanism 110 so that the other end of the threaded sleeve can be inserted into the plug-in hole.

[0076] In a specific implementation, one end of the support member 222 facing the center of the limiting mechanism 110 is provided with a threaded section matching the threaded sleeve, and the threaded section is rotatably connected to the threaded sleeve via the plug-in hole.

[0077] When the embodiment of the present application is actually used, the driving member 221 is rotated to synchronously drive the transmission shaft to rotate, so that the threaded sleeve rotates relative to the plug hole, so that the threaded section on the support member 222 rotates relative to the threaded sleeve, so that the support member 222 can be extended from the inside to the outside or retracted from the outside to the inside. By providing the transmission member 224, it is easy to realize the driving member 221 driving the support member 222.

[0078] In the embodiment of the present application, two supporting members 222 are relatively arranged, and two transmission members 224 are correspondingly arranged. It should be noted that the threaded segments on the supporting members 222 and the threaded directions of the threaded sleeves are specifically arranged according to the actual scene, and the embodiment of the present application does not limit this, and ensures that the threaded segments on each supporting member 222 match the threads of the corresponding threaded sleeves, and at the same time ensures that the two supporting members 222 can move away from or approach each other under the drive of the driving member 221 and the transmission member 224.

[0079] In some embodiments, the driving member 221 is a first bevel gear, the transmission portion 2241 is a second bevel gear, and the connecting portion 2242 is a screw rod.

[0080] The support member 222 has a rotating portion 2221 , and the rotating portion 2221 is rotatably connected to the screw rod to drive the support member 222 to rotate relative to the screw rod.

[0081] In the embodiments of the present application, Figures 2 to 5 As shown, in a specific implementation, the driving member 221 is a first bevel gear, which is rotatably connected to the fixing seat 211, and the transmission part 2241 of the transmission member 224 is a second bevel gear meshingly connected to the first bevel gear, and the axes of the first bevel gear and the second bevel gear are perpendicular. Exemplarily, the rotation ratio of the first bevel gear and the second bevel gear is set to 1:1.

[0082] In the embodiment of the present application, the connecting portion 2242 of the transmission member 224 is configured as a screw rod, and the screw rod is coaxially arranged with the second bevel gear, one end of the screw rod is connected to the second bevel gear by welding or key connection, and the other end of the screw rod is rotatably inserted into the central limit mechanism 110. In addition, a rotating portion 2221 is provided at one end of the support member 222 facing the driving member 221 by an integrated molding method, and the rotating portion 2221 is illustratively a hanging member having a threaded hole, and the threaded hole matches the thread on the screw rod.

[0083] In actual use, the hanging piece on the support member 222 is hung on the screw rod through the threaded hole, and the second bevel gear is driven to rotate synchronously by rotating the first bevel gear, so that the screw rod rotates relative to the center limiting mechanism 110. At this time, the hanging piece on the support member 222 rotates relative to the screw rod, so that the support member 222 can extend from the inside to the outside or shrink from the outside to the inside, so that the two opposite support members 222 can move away from or approach each other.

[0084] In this way, by setting up the gears to transmit each other, the driving member 221 and the transmission member 224 are arranged compactly, and the threaded connection between the hanging member and the screw rod is used to ensure reliable transmission between the transmission member 224 and the support member 222.

[0085] In some embodiments, the cable protection device provided in the embodiment of the present application further includes a knob 230. In a specific configuration, the knob 230 is disposed on the fixing seat 211 and connected to the first bevel gear. In this way, it is convenient for an operator to drive the first bevel gear to rotate by the knob 230, thereby improving the convenience of use.

[0086] In some embodiments, at least three limiting mechanisms 110 include a first limiting assembly 111 , the first limiting assembly 111 includes a first base 1111 and at least one first limiting member 1112 , and the first limiting member 1112 is disposed around an outer wall of the first base 1111 .

[0087] One end of the fixing member 212 facing away from the fixing seat 211 is fixedly connected to the first base 1111 , and one end of the first limiting member 1112 facing away from the driving member 221 is inserted into the supporting member 222 via the supporting member 222 .

[0088] like Figure 4 and Figure 5 As shown, at least three limiting mechanisms 110 include a first limiting assembly 111. In the embodiment of the present application, the first limiting assembly 111 is the limiting mechanism 110 located at the center. Specifically, the first limiting assembly 111 includes a first base 1111 and at least one first limiting member 1112. Exemplarily, the first base 1111 is a hollow columnar structure, and the first limiting member 1112 is arranged on the outer wall of the first base 1111 in an axial direction around the first base 1111.

[0089] In a specific implementation, the fixing seat 211 is located in the first base 1111, and one end of the fixing member 212 facing away from the fixing seat 211 is connected to the inner wall of the first base 1111. Exemplarily, a plug-in hole is provided on the first base 1111, and a first mounting hole 1114 is provided through the first base 1111 and the first stopper 1112 in a radial direction, and the first mounting hole 1114 and the plug-in hole are arranged adjacent to each other, so that after the rotating portion 2221 of the support member 222 is sleeved on the connecting portion 2242 of the transmission member 224, one end of the connecting portion 2242 facing away from the transmission portion 2241 is inserted into the plug-in hole, and the stopper 2222 of the support member 222 passes through the first mounting hole 1114; in this way, the fixing assembly 210 is reliably connected to the first base 1111, and the support member 222 can move relative to the first mounting hole 1114 under the drive of the transmission member 224.

[0090] In the embodiment of the present application, a plurality of heat dissipation holes 114 are provided at intervals on the first base 1111. By providing the heat dissipation holes 114, when the cable is clamped in the protective device and transmits electrical energy, the heat of the cable itself can be dissipated through the heat dissipation holes 114. In addition, the plurality of heat dissipation holes 114 can also reduce the overall weight of the first base 1111, thereby preventing the device from being too heavy and dragging the cable.

[0091] In some embodiments, at least three limiting mechanisms 110 include at least one second limiting assembly 112, the second limiting assembly 112 includes at least two second limiting members 1121, the two second limiting members 1121 form a limiting ring, the limiting ring is inserted on the support member 222 through one end of the support member 222 away from the driving member 221, and the limiting ring is located outside the first limiting member 1112.

[0092] The limiting area 120 includes a first limiting area 121 , and the outer wall of the first limiting member 1112 and the inner wall of the limiting ring form the first limiting area 121 .

[0093] In the embodiments of the present application, Figure 1 , Figure 2 and Figure 6 As shown, the second limiting assembly 112 includes at least two second limiting members 1121. Specifically, the two second limiting members 1121 are arranged to form a limiting ring, and a second mounting hole 1124 is provided on each second limiting member 1121 by punching or the like, that is, two opposite second mounting holes 1124 are provided on the limiting ring, and the limiting ring is inserted on the two supporting members 222 from the supporting member 222 toward one end of the stop portion 2222 through the two second mounting holes 1124.

[0094] It should be noted that the limiting ring is coaxially arranged with the first limiting member 1112, and the limiting ring is located outside the first limiting member 1112, so that the outer wall of the first limiting member 1112 and the inner wall of the limiting ring form a first limiting area 121 for placing the cable.

[0095] In the embodiment of the present application, the second position-limiting assembly 112 further includes a guide member 1125, which is disposed on one of the two second position-limiting members 1121, and the guide member 1125 is located on at least one end of the second position-limiting member 1121; at least one end of the other of the second position-limiting members 1121 is provided with a guide groove 1126, and the guide groove 1126 is correspondingly connected to the guide member 1125. In this way, when the two second position-limiting members 1121 move toward the first base 1111 on the support member 222, the guide member 1125 is connected to the guide groove 1126 to provide guidance when the two second position-limiting members 1121 are surrounded to form a position-limiting ring.

[0096] In the embodiment of the present application, exemplarily, the number of the second limiting components 112 is two, and the two second limiting components 112 are sequentially mounted on the support member 222; that is, one of the second limiting components 112 is formed together with the first limiting component 111 to form a first limiting area 121, and is simultaneously formed together with the other second limiting component 112 to form a third limiting area 123, and the third limiting area 123 is also used to place cables.

[0097] It can be understood that the third limiting area 123 is formed by the two second limiting components 112, and the number of third limiting areas 123 depends on the number of second limiting components 112, which can be multiple. It is adaptively set according to actual usage requirements and is not limited to the embodiment of the present application.

[0098] In some embodiments, at least three limiting mechanisms 110 include a third limiting assembly 113 , which includes at least two second bases 1131 and a third limiting member 1132 disposed on the inner wall of the second base 1131 , and the two second bases 1131 form a protective cover.

[0099] The third limiting member 1132 is inserted on the supporting member 222 through one end of the supporting member 222 away from the driving member 221 , and the protective cover is located outside the limiting ring.

[0100] The limiting area 120 further includes a second limiting area 122 , and the outer wall of the limiting ring and the inner wall of the third limiting member 1132 form the second limiting area 122 .

[0101] In the embodiments of the present application, Figure 1 , Figure 2 and Figure 7 As shown, the third limiting assembly 113 includes at least two second bases 1131 and a third limiting member 1132 coaxially arranged around the inner wall of the second base 1131. Specifically, the two second bases 1131 are surrounded to form a protective cover, and a third mounting hole 1134 is provided in the radial direction through the second base 1131 and the third limiting member 1132 by punching or the like, that is, two relative third mounting holes 1134 are provided on the protective cover.

[0102] In a specific implementation, the protective cover is coaxially arranged with the first base 1111, and the protective cover is inserted on the two support members 222 from one end of the support member 222 toward the stop portion 2222 through the two third mounting holes 1134, and the protective cover is located outside the limiting ring so that the outer wall of the limiting ring and the inner wall of the third limiting member 1132 form a second limiting area 122 for placing the cable.

[0103] In the embodiment of the present application, a plurality of heat dissipation holes 114 are also provided at intervals on the second base 1131 . The functions and effects of the heat dissipation holes 114 are the same as those of the heat dissipation holes 114 on the first base 1111 , and will not be elaborated herein.

[0104] In some embodiments, the first limiting member 1112 has a plurality of first limiting portions 1113 spaced apart from each other, and the second limiting member 1121 has a plurality of first accommodating portions 1122 spaced apart from each other and a plurality of second accommodating portions 1123 spaced apart from each other on two opposite sides, and the first accommodating portions 1122 and the first limiting portions 1113 are arranged correspondingly so that the first accommodating portions 1122 and the first limiting portions 1113 form a first limiting sub-area.

[0105] The third limiting member 1132 has a plurality of second limiting portions 1133 arranged at intervals, and the second limiting portions 1133 are arranged corresponding to the second accommodating portion 1123, so that the second accommodating portion 1123 and the second limiting portions 1133 form a second limiting sub-area. Both the first limiting sub-area and the second limiting sub-area are used to place cables.

[0106] In the embodiments of the present application, Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the first position-limiting portion 1113 corresponds to the first accommodation portion 1122, and the second accommodation portion 1123 corresponds to the second position-limiting portion 1133. Exemplarily, the first position-limiting portion 1113 and the first accommodation portion 1122 are matched arc grooves to form a first position-limiting sub-area, and the second position-limiting portion 1133 and the second accommodation portion 1123 are matched arc grooves to form a second position-limiting sub-area.

[0107] It is understandable that the first limiting area 121 includes a plurality of first limiting sub-areas, and the second limiting area 122 includes a plurality of second limiting sub-areas. In this way, each first limiting sub-area and each second limiting sub-area is used to place a single cable, so as to ensure that each cable can be arranged separately, further improving the protection effect of the embodiment of the present application.

[0108] In some embodiments, the limiting mechanism 110 further includes an assembly part 1135 , and the assembly part 1135 is disposed in a one-to-one correspondence with the second base 1131 , and the assembly parts 1135 are disposed adjacent to each other to fix the second base 1131 .

[0109] In the embodiments of the present application, Figure 1 , Figure 2 and Figure 7 As shown, an assembly part 1135 is provided on the outer wall of the second base 1131 , and the assembly parts 1135 on the two second bases 1131 are arranged adjacent to each other. Exemplarily, the assembly part 1135 has a bolt hole.

[0110] In actual use, by rotating the driving member 221, when the stop member 223 drives the third limit member 1132 and the second limit member 1121 to move toward the first limit member 1112 relative to the support member 222, each limit member clamps the cable in the limiting area 120, and then passes through the bolt holes on the two adjacent assembly parts 1135 in turn through fasteners such as bolts to connect the two assembly parts 1135, thereby reliably fixing the two second bases 1131, thereby adding further connection points to the cable protection device provided in the embodiment of the present application, so as to enhance the stability of the connection between the device and the cable.
