Description

Technical Field

[0001] This invention relates to the field of electrical installation and fixing technology, specifically to an electrical installation and fixing device for electrical engineering. Background Technology

[0002] Electrical installation and fixing devices are key components in electrical engineering used to fix, support, and protect cables, lines, and equipment. Their core function is to ensure the overall safety and stability of the electrical system. Electrical installation and fixing devices provide uniform support force to cables through mechanical support and protection, preventing loosening, wear, or insulation damage. At the same time, the fixing devices can also adapt to different cable specifications through adjustment functions, reducing installation damage, extending cable life, reducing maintenance costs, and making line replacement and maintenance more convenient and safe.

[0003] After electrical wiring is completed, it is generally fixed using electrical installation and fixing devices. However, some electrical wires near the end need to be frequently removed and connected to equipment or lines in different locations. This requires leaving a certain length of wire exposed, which is not convenient for storage and concealment, and will create redundancy after wiring, which is not conducive to the safety of electrical installation. Furthermore, after the existing electrical installation and fixing devices are used to install and fix electrical wires, the length of the wires is often relatively fixed. After being dragged, the wires are easily damaged by external force. Moreover, when the connection point of the electrical wire is far away, the length is insufficient and cannot be adjusted, which is inconvenient for the safety and efficiency of electrical wiring. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an electrical installation and fixing device for electrical engineering, which can store and quickly reel in a portion of electrical wires by winding them up, and can automatically release the wires after pulling them, and can adjust the length of the released electrical wires to facilitate wiring with equipment or lines in different locations.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0006] An electrical installation and fixing device for electrical engineering, comprising:

[0007] The mounting base has a sliding mounting box on top, and the top of the mounting box has a cover. Inside the mounting box are a winding module, a wire feeding drive module, and a take-up module. The winding module has electrical wires wound and stored on it. After the electrical wires are pulled out of the wire feeding drive module, the winding module rotates to release the wires. Under the control of the take-up module, the winding module reverses to take up the wires.

[0008] The winding module includes a winding drum, one end of which is fixed to a rear support plate installed inside the mounting box, and the other end is rotatably provided with a rotating ring. The electrical wire is wound on the winding drum, and one end passes through the wire release hole provided on the rotating ring and is connected to the wire feeding transmission module, while the other end passes through the wire inlet hole provided on one side of the rear support plate.

[0009] Furthermore, the take-up module includes a take-up drum, which is installed in a mounting box on one side of the winding drum, and a drive gear is rotatably mounted at one end. One end of the rotating ring is rotatably mounted on a front support plate installed in the mounting box, and the other end is fitted with an external toothed ring that meshes with the drive gear.

[0010] Furthermore, a fixing plate is sleeved and fixed inside the take-up drum, and a spring is provided between one side of the fixing plate and the take-up drum. The drive gear shaft passes through the fixing plate and is connected to the spring, and the other end of the spring is connected and fixed to the fixing plate. After the drive gear rotates through the spring, it drives the outer gear ring to rotate in the opposite direction.

[0011] Furthermore, a check ratchet is fixedly sleeved on the transmission gear shaft, a locking block is provided inside the take-up drum, a limit groove is provided on the top, the top of the limit groove passes through the cover, the top of the locking block is slidably disposed in the limit groove and is provided with a control button, and a locking spring is provided between one side and the take-up drum, while the other side engages with the check ratchet.

[0012] Furthermore, the wire feeding transmission module includes a wire feeding cylinder disposed in the mounting box. The wire feeding cylinder is provided with a wire feeding hole corresponding to the axis of the winding cylinder, and a clamping wire feeding structure is provided inside the wire feeding hole. A transmission structure is provided on one side. After the electrical wire passes through the wire feeding hole, it drives the clamping wire feeding structure and drives the drive gear to rotate through the transmission structure.

[0013] Furthermore, the clamping and feeding structure includes a U-shaped clamp seat that is slidably disposed inside the feeding cylinder. Multiple U-shaped clamp seats are evenly disposed circumferentially inside the feeding cylinder. Clamping rollers are rotatably disposed inside the clamping clamp seat, and a telescopic tube is disposed between one side of the clamping clamp seat and the feeding cylinder. A clamping spring is disposed inside the telescopic tube.

[0014] Furthermore, the transmission structure includes a support frame disposed on one side of the wire feeding drum. A transmission rod and a transmission sleeve are rotatably disposed inside the support frame. A bevel gear structure is disposed at one end of the transmission sleeve. A bevel gear structure that meshes with one end of the transmission rod is disposed at one end of the transmission sleeve. A transmission gear is disposed at the other end. An internal gear ring is fixed coaxially on the drive gear. The transmission gear and the drive gear are not concentrically disposed, and the top of the transmission gear meshes with the inner side of the internal gear ring.

[0015] Furthermore, one of the U-shaped clamps is arranged horizontally and has a gear box on top. A transmission bevel gear is rotatably mounted on the bottom of the gear box, and a driven bevel gear that meshes with the transmission bevel gear is rotatably mounted on one side. The shaft of the transmission bevel gear is connected to the shaft of the corresponding clamping roller. The shaft of the driven bevel gear is connected to one end of the transmission sleeve by a key and is slidably mounted inside the transmission sleeve.

[0016] Furthermore, the mounting base is provided with a positioning module, which includes a positioning groove on the top of the mounting base. A top block is slidably disposed in the positioning groove. The top of the top block has an inverted V-shaped structure, and a spring tube is provided at the bottom. A positioning spring is disposed inside the spring tube. The mounting box is slidably disposed on the mounting base, and a positioning top groove that matches the top of the top block is provided at the bottom.

[0017] The advantages of this invention compared to the prior art are:

[0018] 1. This invention is equipped with a wire winding module, which can wind and roll up excess electrical wires onto a winding drum for storage, ensuring that the exposed electrical wires are of a moderate length, making wiring and connection convenient and easier to use. It also has an installation box to protect the electrical wires wound and rolled up on the winding drum, providing stronger protection and making the installation and fixing of the electrical wires safer.

[0019] 2. This invention is equipped with a wire feeding drive module, which can rotate the winding drum to release the wire by pulling the external electrical wire, thereby extending the usable length of the electrical wire and facilitating the connection of equipment or lines at greater distances. At the same time, the winding drum can be automatically rotated in the opposite direction by sliding the control button to rewind and store the excess electrical wire back into the installation box. This provides stronger adjustment capability for the electrical wire length, makes it more convenient to use, and makes wiring and connection more efficient.

[0020] 3. The present invention is equipped with a wire feeding transmission module, which can rotate the winding drum to release the wire by pulling the external electrical wire, thereby extending the length of the electrical wire and reducing the pulling and damage to the electrical wire after being dragged, making it safer to use;

[0021] 4. This invention uses winding to store electrical wires, which is less affected by the thickness of the electrical wires. It also has a clamping and feeding structure that can clamp and feed electrical wires of different thicknesses, making it more applicable, more versatile, and more convenient to use.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 6 As shown, an electrical installation and fixing device for electrical engineering includes a mounting base 1 for fixing, a mounting box 2 slidably disposed on the top of the mounting base 1, and a box cover 3 disposed on the top of the mounting box 2. A winding module 4, a wire feeding transmission module 5 and a wire take-up module 6 are disposed inside the mounting box 2. Multiple sets of the winding module 4, the wire feeding transmission module 5 and the wire take-up module 6 are disposed inside the mounting box 2, and each has a plug plate 8 disposed at the bottom. The electrical wire 7 is wound and stored on the winding module 4, and one end leaves the mounting box 2 through the wire feeding transmission module 5.

[0041] As described above, the mounting box 2 is detachably mounted on the mounting base 1. The winding module 4, the wire feeding drive module 5, and the take-up module 6 are installed and fixed inside the mounting box 2 via the insert plate 8. After the box cover 3 is connected and fixed to the mounting base 1, the mounting box 2 is fixed inside the box cover 3. The electrical wire 7 is stored by winding it around the winding module 4. After one end of the wire passing through the wire feeding drive module 5 is pulled, the electrical wire 7 is delivered through the wire feeding drive module 5, which drives the winding module 4 to rotate, thus releasing the electrical wire 7 wound on the winding module 4. The wire winding module 6 is used to prevent the electrical wire 7 inside the mounting box 2 (between the winding module 4 and the wire feeding module 5) from being pulled. It also lengthens and adjusts the electrical wire 7 outside the mounting box 2 and provides buffer protection when the electrical wire 7 outside the mounting box 2 is dragged. When the electrical wire 7 outside the mounting box 2 is pulled out too long, the winding module 4 is driven by the winding module 6 to rotate automatically and wind up the electrical wire 7. The electrical wire 7 outside the mounting box 2 becomes shorter, and the wound electrical wire 7 is rewound and stored on the winding module 4 for storage and protection.

[0042] Combined with appendix Figure 3 Appendix Figure 5 Appendix Figure 14 As shown, the top of the mounting box 2 is open, and the bottom is provided with a mounting slider 21 and a positioning top groove 22. The mounting slider 21 is arranged horizontally from left to right, and a pair of positioning top grooves 22 are symmetrically arranged on the front and rear sides of the mounting slider 21. A mounting plate 23 is horizontally arranged inside the mounting box 2, and multiple mounting sleeves 231 are provided at the bottom of the mounting plate 23. Each mounting sleeve 231 is provided with a screw hole, and a through hole is provided on the side wall of the mounting box 2 corresponding to the screw hole of each mounting sleeve 231.

[0043] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 16 As shown, the top of the mounting base 1 is provided with a mounting groove 11 that runs through the left and right sides, and positioning modules 13 are respectively provided on the front and rear sides of the mounting groove 11. Fixing holes 12 are respectively provided at the four corners of the mounting base 1, and rubber shock-absorbing washers 14 are respectively provided at the bottom of each fixing hole 12. The mounting slider 21 is slidably disposed in the mounting groove 11.

[0044] Combined with appendix Figure 2 Appendix Figure 4 Appendix Figure 16As shown, the positioning module 13 includes a positioning groove 131 set on the top of the mounting base 1. A top block 132 is slidably arranged in the positioning groove 131. The top of the top block 132 has an inverted V-shaped structure and is adapted to the positioning top groove 22. A spring tube 133 is set at the bottom, and a positioning spring 134 is set in the spring tube 133. The mounting box 2 is slidably arranged on the mounting base 1. After the top block 132 is inserted and fitted in the positioning top groove 22, the mounting box 2 is positioned in the middle of the mounting base 1.

[0045] In the above description, the mounting base 1 is fixed with screws, and the mounting slider 21 is inserted into the mounting groove 11 and slid. The mounting box 2 presses down the top block 132 and slides on the mounting base 1 until the top block 132 pops up and is inserted into the corresponding positioning top groove 22. Then the mounting box 2 is positioned in the middle of the mounting base 1.

[0046] Combined with appendix Figure 6 Appendix Figure 7 Appendix Figure 8 As shown, the winding module 4 includes a winding cylinder 41, which is arranged laterally in the mounting box 2. One end of the winding cylinder 41 is fixed to the rear support plate 42, and the other end is rotatably equipped with a rotating ring 45. The rotating ring 45 is provided with a wire release hole 451 (the wire release hole 451 is located on the ring body of the rotating ring 45, and the hole diameter is larger than the thickness of the electrical wire 7, increasing the applicability). A wire inlet hole 46 is provided on one side of the rear support plate 42 (the hole diameter of the wire inlet hole 46 is larger than the thickness of the electrical wire 7, increasing the applicability). The rotating ring 45... The front support plate 43 is rotatably mounted on one end (the front support plate 43 is rotatably mounted relative to the rotating ring 45), and the other end is fitted with an external toothed ring 44. The bottom of the front support plate 43 is inserted into the insertion hole of the mounting plate 23. The bottom of the rear support plate 42 is provided with an insertion plate 8, which is detachably mounted in the mounting box 2. The electrical wire 7 is wound on the winding drum 41, and one end passes through the wire release hole 451 provided on the rotating ring 45 and is connected to the wire feeding transmission module 5. The other end passes through the wire inlet hole 46 provided on one side of the rear support plate 42.

[0047] In the above description, the outer toothed ring 44 drives the rotating ring 45 to rotate, causing the wire feeding hole 451 to rotate the electrical wire 7, increasing or decreasing the number of turns of the electrical wire 7 on the winding drum 41, thereby changing the length of the electrical wire 7 stored on the winding drum 41. The electrical wire 7 is retracted or lengthened by sliding in the wire feeding hole 451, and then sent out of the mounting box 2 through the wire feeding transmission module 5, adjusting the length of the electrical wire 7 on the outside of the mounting box 2.

[0048] Combined with appendix Figure 6 Appendix Figure 12 Appendix Figure 13 Appendix Figure 14As shown, the take-up module 6 includes a take-up drum 61. A bottom plate 8 is provided on the bottom of the take-up drum 61, which is housed in a mounting box 2 on one side of the winding drum 41. A fixing plate 63 is sleeved and fixed inside the take-up drum 61. One end of the take-up drum 61 is rotatably equipped with a drive gear 62 that meshes with an external gear ring 44. A spring-loaded spring 64 is positioned between the other end of the drive gear 62 and the fixing plate 63. An internal gear ring 66 is coaxially fixed on one side of the drive gear 62. The other side's rotating shaft passes through the fixing plate 63 and connects to the spring-loaded spring 64. The other end of the spring-loaded spring 64 is fixed to the fixing plate 63. After the drive gear 62 rotates via the spring-loaded spring 64, it drives the external gear ring 44 to rotate in the opposite direction. Rotating in the opposite direction, on the other side of the fixed plate 63, a check ratchet 65 is sleeved and fixed on the shaft of the drive gear 62. A locking block 67 is provided inside the take-up drum 61 and a limit groove 68 is provided on the top. The top of the limit groove 68 passes through the cover 3. The top of the locking block 67 is slidably disposed in the limit groove 68 and is provided with a control button 69. A locking spring 672 is provided between one side and the take-up drum 61, and a locking ratchet 671 that meshes with the check ratchet 65 is provided on the other side. After the check ratchet 65 and the locking ratchet 671 are engaged, the rotation of the drive gear 62 is restricted in one direction, and the elastic potential energy of the spring 64 cannot be released.

[0049] As described above, under the push of the locking spring 672, the locking ratchet 671 abuts and engages with the check ratchet 65, restricting the rotation of the drive gear 62 in one direction (reverse rotation is locked), and the elastic potential energy of the spring spring 64 cannot be released. After the drive gear 62 rotates, it drives the outer gear ring 44 to rotate, causing the rotating ring 45 to rotate and reducing the number of turns of the electrical wire 7 on the winding drum 41. The electrical wire 7, freed by the reduction in the number of turns, leaves the winding module 4 through the wire release hole 451, providing power for the length adjustment of the electrical wire 7 on the outside of the mounting box 2. When the electrical wire 7 on the outside of the mounting box 2 is too long, manually slide the control button 69 to compress the locking spring 672, and separate the locking ratchet 671 from the check ratchet 65. The spring spring 64 is restored and releases its elastic potential energy, automatically driving the drive gear 62 to rotate in the opposite direction, and the outer gear ring 44 to rotate in the opposite direction, increasing the number of turns of the electrical wire 7 on the winding drum 41, thereby increasing the length of the electrical wire 7 stored on the winding drum 41, and pulling back the electrical wire 7 on the outside of the mounting box 2, thus adjusting the length of the electrical wire 7 on the outside of the mounting box 2.

[0050] Combined with appendix Figure 6 Appendix Figure 9 Appendix Figure 10As shown, the wire feeding transmission module 5 includes a wire feeding cylinder 51 disposed in the mounting box 2. The bottom of the wire feeding cylinder 51 is provided with an insert plate 8, and a wire feeding hole 511 is provided through the front and rear of the winding cylinder 41. Inside the wire feeding hole 511, a clamping wire feeding structure 52 is provided, and a transmission structure 53 connected to the take-up module 6 is provided on one side. After the electrical wire 7 moves in the wire feeding hole 511, it drives the clamping wire feeding structure 52, and drives the drive gear 62 to rotate through the transmission structure 53.

[0051] Combined with appendix Figure 10 Appendix Figure 11 As shown, the clamping and feeding structure 52 includes a U-shaped clamp 522 slidably disposed inside the feeding drum 51. Three U-shaped clamps 522 are evenly arranged circumferentially inside the feeding drum 51, and one of the U-shaped clamps 522 is arranged horizontally. Each U-shaped clamp 522 has a clamping roller 521 rotatably disposed inside, and a telescopic tube 523 is disposed between one side and the feeding drum 51. A clamping spring 524 is disposed inside the telescopic tube 523. Under the action of the clamping spring 524, each clamping roller 521 abuts against the electrical wire 7. A toggle groove 512 is provided on the rear side of the feeding drum 51 corresponding to the horizontally arranged U-shaped clamp 522, and a toggle key 525 is fixedly disposed on the corresponding U-shaped clamp 522. The toggle key 525 is slidably disposed in the toggle groove 512.

[0052] Combined with appendix Figure 9 Appendix Figure 10 Appendix Figure 11 Appendix Figure 12 Appendix Figure 14 As shown, the transmission structure 53 includes a support frame 537 disposed on one side of the wire feeding drum 51. A transmission rod 535 and a transmission sleeve 534 (arranged perpendicularly to each other) are rotatably disposed within the support frame 537. One end of the transmission sleeve 534 is provided with a bevel gear structure, and one end of the transmission rod 535 is provided with a bevel gear structure meshing with one end of the transmission sleeve 534. The other end is provided with a transmission gear 536 that is not concentric with the drive gear 62, and the top of the transmission gear 536 meshes with the inner side of the internal gear ring 66. A toothed part is provided on the top of the horizontally arranged U-shaped clamp 522. The gear box 531 has a transmission bevel gear 532 rotatably mounted at its bottom, and a driven bevel gear 533 rotatably mounted on one side to mesh with the transmission bevel gear 532. The shaft of the transmission bevel gear 532 is connected to the shaft of the corresponding clamping roller 521. The shaft of the driven bevel gear 533 is connected to one end of the transmission sleeve 534 by a key and is slidably mounted inside the transmission sleeve 534. A gear housing 538 is mounted on the support frame 537 corresponding to the drive gear 62. After the gear housing 538 abuts against the take-up drum 61, the drive gear 62 is arranged inside the gear housing 538, with one side exposed to mesh with the outer gear ring 44.

[0053] In the above description, after the electrical wire 7 passes through the wire feeding hole 511, each U-shaped clamp 522 slides and compresses the clamping spring 524 (the position of the U-shaped clamp 522 after sliding is different for electrical wires of different thicknesses 7), so that each clamping roller 521 abuts against the electrical wire 7. The horizontally arranged U-shaped clamps 522 drive the gear box 531 to move, so that the driven bevel gear 533 shaft slides in the transmission sleeve 534, pulling the electrical wire 7 outward. After it moves in the wire feeding hole 511, each clamping roller 521 rolls with the wire feeding hole 511, and then drives the internal gear ring 66 to rotate through the transmission structure 53, so that the drive gear 62 drives the external gear ring 44 to rotate, and reduces the winding of the electrical wire 7 on the winding drum 41. The number of turns, due to the reduction in the number of winding turns, frees the electrical wire 7 and leaves the winding module 4 through the wire release hole 451. This provides electrical wire 7 for length adjustment on the outside of the mounting box 2, preventing the electrical wire 7 from being pulled between the winding module 4 and the wire feeding transmission module 5. After the spring 64 returns to its original state and drives the drive gear 62 to rotate in the opposite direction, it drives the corresponding clamping roller 521 to roll in the opposite direction through the transmission structure 53, assisting the electrical wire 7 on the outside of the mounting box 2 to be retracted into the mounting box 2. Manually sliding the toggle key 525 outwards can cause the corresponding U-shaped clamp 522 to drive the clamping roller 521 to leave the electrical wire 7, breaking the influence between the electrical wire 7 and the transmission structure 53, making it easier for the electrical wire 7 to be arranged in the mounting box 2.

[0054] Combined with appendix Figure 6 Appendix Figure 9 Appendix Figure 13 Appendix Figure 15 As shown, the insert plate 8 passes through the mounting plate 23 and is arranged between the side wall of the mounting box 2 and the corresponding mounting sleeve 231, and the insert plate 8 has a through hole corresponding to the screw hole of the mounting sleeve 231.

[0055] As described above, after the insert plate 8 passes through the mounting plate 23, the insert plate 8 is fixed between the side wall of the mounting box 2 and the corresponding mounting sleeve 231 by screws, so that the corresponding winding module 4, wire feeding transmission module 5 and wire take-up module 6 are detachably installed and fixed in the mounting box 2.

[0056] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 16 As shown, the cover 3 is movably sleeved on the mounting box 2, and the side wall is provided with wire grooves 31 corresponding to each wire inlet hole 46 and wire delivery hole 511 to avoid the electrical wires 7. The front and rear sides of the cover 3 are respectively provided with fixing sleeves 32, and the top surface of the mounting base 1 is provided with mounting screw holes 15 corresponding to the fixing sleeves 32.

[0057] As described above, after the mounting box 2 is positioned in the middle of the mounting base 1 by the positioning module 13, the box cover 3 is closed and detachably fixed to the mounting base 1 by screws, so that the mounting box 2 is fixed inside the box cover 3, and the box cover 3 protects the winding module 4, the wire feeding transmission module 5, the wire take-up module 6 and the electrical wire 7 inside the mounting box 2.

[0058] In a specific implementation of this invention: the mounting base 1 is fixed on the mounting positioning, and the mounting box 2 is arranged in the middle of the mounting base 1 through the positioning module 13. After the wire feeding transmission module 5 and the wire take-up module 6 are respectively installed in the corresponding positions inside the mounting box 2, the electrical wire 7 is arranged on the winding module 4. One end of the electrical wire 7 is passed through the wire inlet hole 46 and the wire outlet hole 451 in sequence, leaving a certain length of electrical wire 7 (the length of electrical wire 7 left is the length of the electrical wire 7 to be stored and the length of the electrical wire 7 on the outside of the mounting box 2). (The sum of the two), manually rotate the outer toothed ring 44 to make the rotating ring 45 rotate and drive the electrical wire 7 to wind onto the winding drum 41 (leaving a section of electrical wire 7 outside the rotating ring 45), install the winding module 4 in the corresponding position in the mounting box 2, and set one end of the electrical wire 7 through the wire feeding hole 511. Slide the toggle key 525 to make the corresponding U-shaped clamp 522 drive the clamping roller 521 to disengage from the electrical wire 7, disconnecting the electrical wire 7 from the transmission structure 53, and facilitating the arrangement of the electrical wire 7 in the mounting box 2. To prevent the rotating ring 45 from rotating when the electrical wire 7 passes through the wire feeding hole 511, the cover 3 is closed and detachably fixed to the mounting base 1 with screws, thus fixing the mounting box 2 inside the cover 3. The cover 3 also protects the winding module 4, the wire feeding transmission module 5, the take-up module 6, and the electrical wire 7 inside the mounting box 2. Pulling one end of the electrical wire 7 increases the length of the electrical wire 7 on the outside of the mounting box 2, facilitating connection to equipment or lines. During this process, the transmission structure 53 drives the drive gear 62 to rotate. Turning the spring 64 tightens the spring. After the wiring is completed, the control button 69 on the top of the sliding cover 3 compresses the locking spring 672 and separates the locking ratchet 671 from the check ratchet 65. The spring 64 is restored and releases its elastic potential energy, automatically driving the drive gear 62 to rotate in the opposite direction, and the outer gear ring 44 to rotate in the opposite direction, thereby increasing the number of turns of the electrical wire 7 on the winding drum 41 and pulling back the electrical wire 7 on the outside of the mounting box 2, so that the length of the electrical wire 7 on the outside of the mounting box 2 is adjusted to a suitable length.

[0059] When the electrical wire 7 on the outside of the mounting box 2 is dragged or is too short, the electrical wire 7 on the outside of the mounting box 2 is pulled. When the electrical wire 7 passes through the wire feeding hole 511, it drives the clamping roller 521 to rotate, and drives the drive gear 62 to rotate through the transmission structure 53. This causes the outer gear ring 44 to rotate, and reduces the number of turns of the electrical wire 7 on the winding drum 41. The electrical wire 7 is lengthened and supplied to the wire feeding transmission module 5, which increases the length of the electrical wire 7 on the outside of the mounting box 2 and reduces the external force pulling on the electrical wire 7, thus protecting the electrical wire 7.

[0060] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0061] The working principle of this invention is as follows: The electrical wire 7 is wound around the winding drum 41 inside the mounting box 2 for storage and protection. At the same time, the mechanical transmission module converts the pulling action of the electrical wire 7 into gear rotation, causing one end of the electrical wire 7 to rotate around the winding drum 41. This increases or decreases the number of turns of the electrical wire 7 on the winding drum 41, thereby changing the length of the electrical wire 7 stored on the winding drum 41. The released electrical wire 7 is then provided to the wire feeding transmission module 5 for feeding, achieving the effect of adjusting the length of the electrical wire 7 on the outside of the mounting box 2 and preventing dragging.

[0062] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
