Abstract
Description
Technical Field
[0001] The present application relates to the field of electrical engineering technology, and in particular to a cable stripping device for electrical engineering. Background Art
[0002] In electrical engineering, cables are covered with an insulating sheath. When connecting the wire to a device, some of the insulation needs to be stripped to expose the conductor. The wire to be stripped is placed in a corresponding stripping hole of a wire stripper. The stripping hole's clamping mechanism secures the insulation, and then axial tension is applied to separate the insulation at the end of the wire from the internal conductor. This method relies on friction between the stripping hole and the insulation to achieve stripping. Its simple process and low equipment cost make it widely used in wire pretreatment.
[0003] However, during the stripping process, the aforementioned traditional wire stripping methods apply axial tension directly to the entire wire, causing non-uniform stress within the conductor. For highly ductile conductor materials such as copper and aluminum, wire deformation, reduced cross-sectional area, and even breakage are common. This wire deformation reduces the reliability of subsequent connection processes such as terminal crimping and welding, potentially leading to increased contact resistance, unstable conductivity, and even insulation breakdown or signal transmission anomalies in harsh environments such as high voltage and high frequency.
[0004] Therefore, the present application provides a cable stripping device for electrical engineering to solve the above problems. Summary of the Invention
[0005] The present application provides a cable stripping device for electrical engineering, which aims to solve the problems raised in the background art that the existing method of stripping the insulation layer by axial tension easily causes the wire to be subjected to non-uniform stress, thereby causing tensile deformation and reduction of cross-sectional area.
[0006] To achieve the above-mentioned object, the present application provides the following technical solution: a cable stripping device for electrical engineering, comprising a positioning tube 1, a movable tube 2 rotatably disposed at one end of the positioning tube 1, and a cutter 3 disposed inside the movable tube 2; To facilitate radial and axial cutting of the cable, the movable tube 2 is internally provided with an angle adjustment mechanism 4 for adjusting the angle of the cutter 3. The angle adjustment mechanism 4 can slide on the movable tube 2 along the cable axis and in a direction perpendicular to the cable axis. The angle adjustment mechanism 4 includes a fixed sleeve 41, a rotating shaft 42 rotatably inserted into the fixed sleeve 41 and connected to the top of the cutter 3, and a drive motor 43 fixedly mounted on the fixed sleeve 41. The output shaft of the drive motor 43 is fixedly connected to one end of the rotating shaft 42. The fixed sleeve 41 is provided with a right-angle positioning groove 44, and a positioning rod 45 fixedly connected to the rotating shaft 42 is inserted into the right-angle positioning groove 44. The adjustable angle of the cutter 3 achieves precise radial and axial cutting of the cable insulation layer, avoiding the problem of wire deformation caused by traditional tensile stripping, and improving the stripping quality and efficiency. The right-angle positioning groove 44 and the positioning rod 45 cooperate to quickly determine the cutting direction of the cutter 3, simplifying the operation process.
[0007] Preferably, three cutters 3 are provided, and the three cutters 3 are equidistantly arranged in an annular pattern on the inner side of the movable tube 2. The three cutters 3 are arranged in an annular pattern so that the cable insulation layer can be cut circumferentially at the same time, reducing the number of rotations for a single cut and improving cutting efficiency. The equidistant arrangement evenly distributes the cutting force, avoiding damage to the insulation layer or the conductor caused by excessive local stress.
[0008] Preferably, to improve the cutting efficiency of the cutter 3, the bottom of the cutter 3 is V-shaped, and the cross-sections on both sides are also V-shaped. The V-shaped bottom and cross-section design can concentrate cutting stress, reduce cutting resistance, make it easier for the cutter 3 to penetrate the insulation layer, and improve cutting efficiency. At the same time, it also reduces the contact area between the cutter and the cable, reduces frictional heat, and extends the service life of the cutter.
[0009] Preferably, to facilitate insertion of the cable into the positioning tube 1, the end of the positioning tube 1 away from the movable tube 2 is tapered. The tapered structure facilitates quick insertion of the cable into the positioning tube 1, reducing the difficulty of alignment during insertion; the guiding effect prevents damage to the cable from friction with the edge of the tube opening, improving operational convenience.
[0010] Preferably, to reduce damage to the cable conductors by the cutter 3, a limiting slot 421 is defined within the rotating shaft 42, a limiting slide 422 is disposed within the limiting slot 421, a connecting rod 423 fixedly connected to the limiting slide 422 is slidably inserted into the end of the rotating shaft 42 remote from the drive motor 43, the connecting rod 423 being fixedly connected to the cutter 3, and a first spring 424 fixedly connected to the end of the limiting slide 422 remote from the connecting rod 423 is disposed within the limiting slot 421. The elastic expansion and contraction of the first spring 424 provides the cutter 3 with a buffering function during cutting. When the cutter 3 contacts the internal conductors, the spring compresses and drives the cutter 3 back, preventing excessive cutting and damage to the conductors.
[0011] Preferably, to prevent the cable from moving during the cutting process, the positioning tube 1 is provided with a fixing mechanism 5 for fixing the cable in position. The fixing mechanism 5 includes a clamping plate 51 arranged relative to the inner side of the positioning tube 1. A guide rod 52 fixedly connected to the clamping plate 51 is slidably inserted into the positioning tube 1. An auxiliary push plate 53 is fixedly connected to the end of the guide rod 52 away from the clamping plate 51. A second spring 54 is sleeved on the guide rod 52 between the auxiliary push plate 53 and the positioning tube 1. The clamping plate 51 clamps the cable to prevent axial or circumferential movement of the cable during cutting, ensuring accurate cutting position. The second spring 54 automatically resets the clamping plate 51, facilitating rapid loading and unloading.
[0012] Preferably, to increase friction between the clamping plate 51 and the cable insulation layer, a non-slip pad 511 is fixedly connected to the end of the clamping plate 51 away from the guide rod 52. The non-slip pad 511 has anti-slip grooves on the side facing the cable. The non-slip pad 511 and the anti-slip grooves increase friction between the clamping plate 51 and the cable insulation layer, preventing the cable from slipping during clamping and improving secure fixation. This is particularly suitable for cables with smooth surfaces.
[0013] Preferably, in order to improve the stability of the cutter 3 in cutting the cable insulation layer: a correction mechanism 6 for centering the cable is provided on the movable tube 2, and the correction mechanism 6 includes a ring sleeve 61 that moves axially on the movable tube 2 and an inner gear ring 62 rotatably provided in the ring sleeve 61, and three gears 63 that are meshed with the inner gear ring 62 are rotatably provided in an annular array inside the ring sleeve 61, and a rack 64 that is meshed with the gear 63 is inserted into the ring sleeve 61 through a radial through groove, and a splint 65 is fixedly connected to the rack 64 toward one end of the cable, and a worm gear 66 is provided on the outer fixed sleeve of the inner gear ring 62, and a worm 67 that is meshed with the worm gear 66 is rotatably inserted into the ring sleeve 61, and a guide groove 21 for axial and radial movement of the rack 64 is provided on the movable tube 2, and the fixed sleeve 41 is fixedly inserted on the splint 65. By adjusting the position of the clamping plate 65, the cable axis is aligned with the axis of the movable tube 2, ensuring that the cutter 3 always cuts perpendicularly to the cable surface, improving cutting stability and accuracy, and avoiding incomplete cutting or wire damage due to eccentricity.
[0014] Preferably, to reduce friction between the clamping plate 65 and the cable, a ball bearing 651 is embedded in the clamping plate 65 on one side thereof, symmetrically rotating toward the cable. The ball bearing 651 converts sliding friction between the clamping plate 65 and the cable into rolling friction, reducing resistance to cable movement during calibration, preventing the clamping plate 65 from scratching the cable insulation, and making cable center calibration more flexible and smooth.
[0015] Preferably, the peeling device further includes a control system 7, comprising a controller 71 fixedly mounted on the collar 61 and an operating panel 72 disposed on the controller 71. The controller 71 is electrically connected to the operating panel 72 and the drive motor 43. The operating panel 72 is provided with a plurality of control buttons and a display screen. This integrated control system enables automated operation, allowing the user to input cutting parameters (such as cutting angle) through the operating panel 72 and monitor the cutting process in real time, thereby enhancing the intelligence level and ease of operation of the device.
[0016] This application uses a cutter with adjustable angle to achieve precise radial and axial cutting of the cable insulation layer, avoiding the wire deformation problem caused by traditional tensile wire stripping, and improving the stripping quality and efficiency; the limiting effect of the right-angle positioning groove on the positioning rod can ensure that the cutter maintains a stable angle during the cutting process, improving the integrity of radial and circumferential cutting and the straightness of axial linear cutting, while reducing manual adjustment errors, and significantly improving the automation level and processing accuracy of the wire stripping operation.
[0017] This application utilizes a first spring's elastic connection to allow the cutter to float axially along the rotating shaft during cutting, creating an "elastic cutting" mechanism. When the cutter contacts the cable's internal conductors, the reaction force from the conductors compresses the first spring, causing the cutter to automatically retract, preventing the blade from directly cutting into the conductors. This effectively protects the conductor's integrity and is particularly suitable for thin-diameter cables where the difference between the insulation and the conductor diameter is small.
[0018] This application uses a manually operated auxiliary push plate to drive the clamping plate to clamp the cable, and a second spring provides a reset force, enabling rapid clamping and release. The clamping plate's securement of the cable effectively prevents deviations in the cutting position caused by axial movement or circumferential rotation of the cable during cutting, ensuring that the cutter precisely targets the target area. The spring reset design eliminates the tedious adjustment steps of traditional mechanical clamps, improving operational efficiency and making it suitable for rapid positioning of cables of varying outer diameters.
[0019] This application utilizes manual adjustment of the worm gear to synchronously control the radial movement of the three clamping plates, precisely aligning the cable axis with the axis of the movable tube. This eliminates the problem of uneven force on one side of the cutter due to cable eccentricity, ensuring consistent cutting depth and a smooth cut surface. After centering, axial cutting requires only moving the ring to drive the cutter in a straight line along the cable axis, eliminating skewed cutting paths caused by cable deviation and improving the consistency of stripping quality.

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0023] Example 1 This embodiment provides a cable stripping device for electrical engineering, such as Figure 1-7 As shown, the peeling device includes a positioning tube 1, a movable tube 2 rotatably arranged at one end of the positioning tube 1, and a cutter 3 arranged on the inner side of the movable tube 2; wherein, the positioning tube 1 and the movable tube 2 are both made of transparent material (such as acrylic plate).
[0024] In order to facilitate radial and axial cutting of the cable: an angle adjustment mechanism 4 for adjusting the angle of the cutter 3 is provided inside the movable tube 2, and the angle adjustment mechanism 4 can slide on the movable tube 2 along the axis of the cable and in a direction perpendicular to the axis of the cable. The angle adjustment mechanism 4 includes a fixed sleeve 41, a rotating shaft 42 rotatably inserted in the fixed sleeve 41 and connected to the top of the cutter 3, and a drive motor 43 fixedly installed on the fixed sleeve 41. The output shaft of the drive motor 43 is fixedly connected to one end of the rotating shaft 42. A right-angle positioning groove 44 is provided on the fixed sleeve 41, and a positioning rod 45 fixedly connected to the rotating shaft 42 is inserted inside the right-angle positioning groove 44. The adjustable angle of the cutter 3 enables precise radial and axial cutting of the cable insulation, avoiding the wire deformation caused by traditional tensile stripping and improving stripping quality and efficiency. The right-angle positioning slot 44 limits the positioning rod 45, ensuring that the cutter 3 maintains a stable angle during the cutting process, improving the integrity of the radial and circumferential cuts and the straightness of the axial cuts. This also reduces manual adjustment errors and significantly enhances the automation and processing accuracy of the stripping operation. When radial cutting is required, the drive motor 43 drives the rotating shaft 42 to rotate clockwise, and the positioning rod 45 slides along the horizontal section of the right-angle positioning slot 44, aligning the plane of the cutter 3 with the cable axis. The cutter 3 then moves radially toward the cable, and the movable tube 2 rotates to drive the cutter 3 to complete the circumferential cut. When axial cutting is required, the drive motor 43 drives the rotating shaft 42 to rotate counterclockwise, and the positioning rod 45 slides along the vertical section of the right-angle positioning slot 44, aligning the plane of the cutter 3 with the cable axis. The cutter 3 then moves axially to complete the longitudinal cut. This coordinated control of angle and movement direction achieves a combined cutting function.
[0025] Three cutters 3 are provided, arranged equidistantly in a circular pattern on the inner side of the movable tube 2. The three cutters 3 are distributed in a circular pattern on the inner side of the movable tube 2 at 120° intervals, forming a symmetrical cutting structure. During circumferential cutting, cutting forces are simultaneously applied to the cable insulation layer in three directions, evenly distributing the cutting resistance. This prevents insulation tearing or localized stress concentration caused by single-point cutting, and improves the flatness of the cut surface. Compared to a single cutter 3 requiring 360° rotation, the synchronous operation of the three cutters 3 reduces the circumferential cutting time to one-third, significantly improving wire stripping efficiency and making it particularly suitable for batch operations. As the movable tube 2 drives the three cutters 3 to rotate around the cable axis, the blade of each cutter 3 contacts the outer surface of the cable. Utilizing the geometric symmetry of the circular array, a continuous, closed cutting path is formed during the rotation process. When the movable tube 2 rotates 120°, the three cutters 3 jointly complete a 360° circumferential cut, eliminating the need for repeated rotation. Combined with the radial positioning of the angle adjustment mechanism 4, a quick and complete circumferential cutting operation is achieved.
[0026] To improve the cutting efficiency of cutter 3: the bottom of cutter 3 is V-shaped, and the cross-sections on both sides are also V-shaped. The V-shaped design of the bottom of cutter 3 (including the bottom tip and the two side bevels) can convert the vertical pressure during cutting into a horizontal force component, reducing the axial thrust required to cut into the insulation layer, making the cutting process more labor-saving and efficient. The V-shaped tip can accurately pierce the surface of the insulation layer, and the V-shaped bevels on both sides guide the blade to cut in the predetermined direction, reducing cutting deviation, while also reducing the contact area between cutter 3 and the insulation layer, reducing frictional heat, and extending the service life of cutter 3. For insulation layers of different thicknesses, the V-shaped structure can adaptively adjust the cutting depth to avoid excessive cutting and damage to the wire. During cutting, the V-shaped tip first contacts the cable insulation layer, and the stress concentration at the tip causes the insulation layer to rupture. Then, the V-shaped bevels on both sides extend the cutting path along the rupture. Since the V-shaped bevel forms an acute angle with the surface of the insulation layer, the cutting force can be decomposed into a pressure perpendicular to the bevel and a thrust parallel to the bevel. The latter pushes the cutter 3 to slide radially or axially, and uses the wedge mechanics principle to achieve "small force for large cutting effect", reducing the operation difficulty and increasing the cutting speed.
[0027] In order to facilitate the insertion of the cable into the positioning tube 1: the end of the positioning tube 1 away from the movable tube 2 is in the shape of a tapered tube. The end of the positioning tube 1 away from the movable tube 2 is designed to be in the shape of a tapered tube. Its tapered structure can guide the inserted cable, and the cable axis can be automatically aligned with the axis of the positioning tube 1 without manual precise alignment, lowering the operating threshold; the smooth transition surface of the tapered end reduces the friction between the cable surface and the tube end, avoiding scratches on the insulation layer caused by hard contact during the insertion process, and is especially suitable for lossless insertion of thin-walled or highly flexible cables. The end of the positioning tube 1 away from the movable tube 2 is flared. When the cable is inserted, the tapered end guides the center of the cable to automatically align with the axis of the positioning tube 1, reducing manual alignment errors and allowing the cable to smoothly pass through the positioning tube 1 to reach the cutting position.
[0028] To minimize damage to the cable conductors caused by the cutter 3, a square retaining slot 421 is defined within the rotating shaft 42. A square retaining slide 422 is positioned within the retaining slot 421. A connecting rod 423, fixedly connected to the retaining slide 422, is slidably inserted into the end of the rotating shaft 42 remote from the drive motor 43. The connecting rod 423 is fixedly connected to the cutter 3. A first spring 424 is positioned within the retaining slot 421 and fixedly connected to the end of the retaining slide 422 remote from the connecting rod 423. The elastic connection of the first spring 424 allows the cutter 3 to float axially along the rotating shaft 42 during cutting, creating an "elastic cutting" mechanism. When the cutter 3 contacts the cable conductors (e.g., if the cutting depth exceeds the insulation thickness), the reaction force of the conductors compresses the first spring 424, causing the cutter 3 to automatically retract, preventing the blade from directly cutting into the conductors. This effectively protects the conductor's integrity and is particularly suitable for thin-diameter cables where the difference between the insulation and conductor diameters is small. Cutter 3 is fixedly connected to a square limiting slide 422 via a connecting rod 423. The square limiting slide 422 slides within a square limiting slot 421. A first spring 424 provides an initial preload to maintain the cutter 3 in its normal cutting position. When the cutting depth exceeds the thickness of the insulation layer, the conductor exerts a reverse thrust on the cutter 3, pushing the square limiting slide 422 to compress the spring and slide along the square limiting slot 421. The cutter 3 then retreats until the blade only acts on the insulation layer. When the cut is complete, the spring's return force returns the cutter 3 to its initial position, achieving adaptive control of the cutting depth.
[0029] The stripping device also includes a control system 7, which consists of a controller 71 fixedly mounted on the collar 61 and an operating panel 72 mounted on the controller 71. The controller 71 is electrically connected to the operating panel 72 and the drive motor 43. The operating panel 72 is equipped with multiple control buttons and a display screen. The integrated control system 7 enables automated and intelligent operation of the stripping device. Users can input cutting parameters (such as the angle of the cutter blade 3) through the operating panel 72. The controller 71 drives the drive motor 43 according to preset programs or real-time instructions, ensuring coordinated operation of all components. The display screen displays operating status (such as motor speed and fault alarms) in real time, facilitating user monitoring and debugging, reducing manual operation errors, and improving device usability and consistent processing accuracy. The control buttons on the operating panel 72 convert user commands into electrical signals, which are transmitted to the controller 71 (such as a PLC or single-chip microcomputer). The controller 71 analyzes the signals through an algorithm and sends speed and direction commands to the drive motor 43. The display screen visualizes device status through a human-machine interface (HMI), supporting real-time parameter adjustment and fault diagnosis.
[0030] Example 2 Different from Example 1, in order to prevent the cable from moving during the process of cutting the cable insulation layer: a fixing mechanism 5 for fixing the position of the cable is provided on the positioning tube 1, and the fixing mechanism 5 includes a clamping plate 51 relatively arranged on the inner side of the positioning tube 1, and a guide rod 52 fixedly connected to the clamping plate 51 is slidably inserted on the positioning tube 1, and an auxiliary push plate 53 is fixedly connected to the end of the guide rod 52 away from the clamping plate 51, and a second spring 54 is sleeved between the corresponding auxiliary push plate 53 and the positioning tube 1 on the guide rod 52. The clamping plate 51 can be driven to clamp the cable by manually operating the auxiliary push plate 53, and the second spring 54 provides a reset force to achieve rapid clamping and loosening. The fixation of the cable by the clamping plate 51 can effectively prevent the cutting position from being offset due to axial movement or circumferential rotation of the cable during the cutting process, ensuring that the cutter 3 acts accurately on the target area; the spring reset design avoids the cumbersome adjustment steps of traditional mechanical clamps, improves operating efficiency, and is suitable for rapid positioning of cables with different outer diameters. When the user squeezes the auxiliary push plates 53 inward, they drive the clamping plates 51, via the guide rods 52, radially along the inner wall of the positioning tube 1 until the plates 51 contact the cable insulation, securing the cable through friction. Once cutting is complete, the auxiliary push plates 53 are released, and the elastic force of the second spring 54 pushes them outward, simultaneously releasing the clamping plates 51 and releasing their grip. The symmetrical structure of the clamping plates 51 ensures even distribution of clamping force, preventing cable deformation caused by unilateral force.
[0031] In order to increase the friction between the clamping plate 51 and the cable insulation layer: the end of the clamping plate 51 away from the guide rod 52 is fixedly connected to an anti-slip pad 511, and the side of the anti-slip pad 511 facing the cable is provided with anti-slip grooves. The anti-slip pad 511 is made of a material with a high friction coefficient (such as rubber), and the anti-slip grooves on its surface (such as serrated or grid-like) can be embedded in the tiny pits on the surface of the cable insulation layer to form a mechanical bite, which significantly increases the static friction between the clamping plate 51 and the cable, and can effectively prevent the cable from sliding even in the case of high-speed cutting or large-diameter cables. The anti-slip design avoids the positioning failure problem caused by insufficient friction of traditional smooth clamping surfaces, and improves the reliability of the fixing mechanism 5. When the clamping plate 51 clamps the cable, the elastic material of the anti-slip pad 511 first adheres to the cable surface to fill the gaps in the irregular curved surface, and then the anti-slip grooves and the convex and concave structures on the surface of the insulation layer are interlocked to increase the contact area and friction coefficient. According to the principles of friction mechanics, the tooth-shaped design of the pattern can convert the clamping force into resistance in multiple directions, suppressing the axial and circumferential displacement of the cable and ensuring the stable position of the cable during the cutting process.
[0032] Example 3 Different from Example 1, in order to improve the stability of the cutter 3 in cutting the cable insulation layer: a correction mechanism 6 for centering the cable is provided on the movable tube 2, and the correction mechanism 6 includes a ring sleeve 61 that moves axially on the movable tube 2 and an inner gear ring 62 rotatably provided in the ring sleeve 61, and three gears 63 that are meshed with the inner gear ring 62 are rotatably provided in an annular array inside the ring sleeve 61, and a rack 64 that is meshed with the gear 63 is inserted into the ring sleeve 61 through a radial groove, and a splint 65 is fixedly connected to the rack 64 toward one end of the cable, and a worm gear 66 is provided on the outer fixed sleeve of the inner gear ring 62, and a worm 67 that is meshed with the worm gear 66 is rotatably inserted into the ring sleeve 61, and a guide groove 21 for axial and radial movement of the rack 64 is provided on the movable tube 2, and a fixed sleeve 41 is fixedly inserted on the splint 65. Manual adjustment of the worm 67 synchronizes the radial movement of the three clamping plates 65, precisely aligning the cable axis with the axis of the movable tube 2. This eliminates uneven force on one side of the cutter 3 caused by cable eccentricity, ensuring consistent cutting depth and a smooth cut surface. After centering, axial cutting requires only moving the ring 61 to drive the cutter 3 in a linear motion along the cable axis, eliminating skewed cutting paths caused by cable deviation and improving consistent stripping quality. Rotating the worm 67 engages the worm gear 66, driving the internal gear ring 62, which in turn drives the three gears 63 to rotate synchronously. These gears 63 engage the rack 64, causing it to move radially along the guide groove 21, thereby moving the clamping plates 65 toward or away from the cable. The three clamping plates 65 are spaced 120 degrees apart. Synchronous adjustment pushes the cable toward the center until the clamping plates 65 evenly contact the cable's outer surface, effectively aligning the cable axis with the equipment axis. After calibration, the ring sleeve 61 moves axially along the movable tube 2 and drives the cutter 3 to perform stable axial cutting through the fixed sleeve 41 .
[0033] To reduce friction between the clamping plate 65 and the cable, balls 651 are symmetrically mounted on the side of the clamping plate 65 that rotates toward the cable. Balls 651 convert sliding friction between the clamping plate 65 and the cable into rolling friction, allowing for fine-tuning of the cable's position during centering, reducing resistance and preventing insulation wear caused by hard friction. The spherical design of balls 651 ensures point contact with the cable surface, reducing contact stress and protecting the thin-walled insulation from damage. It also allows for more flexible movement of the clamping plate 65 and improves the response speed of centering. When the clamping plate 65 moves radially under the drive of the correction mechanism 6, balls 651 contact the outer surface of the cable and rotate freely. The rolling resistance of balls 651 is much smaller than sliding friction, allowing the cable to adjust its position with minimal external force until it is evenly contacted by balls 651 on all three clamping plates 65. Even if the cable rotates slightly due to force during cutting, balls 651 rotate with it, maintaining a dynamic fit between the clamping plate 65 and the cable without compromising centering accuracy.
[0034] The wiring diagram of the drive motor 43 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to actual use, so the control method and wiring layout of the drive motor 43 are no longer explained in detail.
[0035] The control method of this application is controlled by the controller 71. The control circuit of the controller 71 can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. This application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.
[0036] It should be noted that the various standard parts used in this application are all available on the market, and non-standard parts can be specially customized. The connection method adopted in this application is also a very common means in the mechanical field and will not be repeated here.
[0037] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
