DETAILED DESCRIPTION

[0030] See also Figure 1-3 In an embodiment of the present invention, a wire-opening device for an energy storage charging harness includes a shell 1, a handle 2 is fixedly connected to the middle of the outer wall of one side of the shell 1, symmetrical shells 3 are rotatably connected to the two sides of the shell 1, and the inner cavity of the shell 1 is elastically connected to a symmetrical positioning plate 17, and a symmetrical first balance retraction rod 13 is fixedly connected between the positioning plate 17 and the inner cavity side wall of the shell 1. The first balance retraction rod 13 can automatically retract as the position of the positioning plate 17 changes, so as to keep the positioning plate 17 stable when moving. A sleeve 19 is fixedly connected between the symmetrical positioning plates 17, and a blade 34 is provided in the inner cavity of the sleeve 19. A through slot 37 for cooperating with the blade 34 is opened in the middle of one end of the sleeve 19 away from the first balance retraction rod 13. The outer wall of the shell 1 is symmetrically provided with an adjustment mechanism for adjusting the length of the blade 34. When the output end of the adjustment mechanism is close to the handle 2, the blade 34 will gradually extend out of the through slot 37 and move in a direction away from the first balance retraction rod 13.

[0031] A screw rod 4 is rotatably connected to the middle of the upper end of the shell 3, and a clamping plate 5 is symmetrically arranged in the inner cavity of the shell 3. The clamping plate 5 and the inner cavity side wall of the shell 3 are also connected through a symmetrical second balancing contraction rod 13. The middle part of the clamping plate 5 located at the top is threadedly connected to the lower part of the screw rod 4, that is, the clamping plate 5 can be driven to move in the vertical direction by rotating the screw 4. The ends of the symmetrical clamping plates 5 away from the second balancing contraction rod 13 are fixedly connected to symmetrical cross bars 14, and the ends of the cross bars 14 away from the clamping plates 5 are fixedly connected to racks 16. A first gear 15 is rotatably connected to the middle part of the inner cavity side wall of the shell 3, and the first gear 15 and the rack 16 are meshed with each other, that is, when the screw 4 is rotated to drive the clamping plate 5 located at the top to move, the clamping plate 5 located at the top The cross bar 14 will drive the rack 16 located above to move synchronously, thereby driving the first gear 15 to rotate, thereby driving the rack 16 and the cross bar 14 located below to move synchronously, and then driving the clamping plate 5 located below to move synchronously, so that the clamping plate 5 can symmetrically approach or move away from the center position of the shell 3 synchronously, so that the energy storage charging harness that needs to be opened can be kept at the center position of the shell 3 after being fixed. Through the symmetrical arrangement of the shell 3 and the clamping plate 5, both ends of the part where the energy storage charging harness needs to be opened can be stably clamped, thereby avoiding the energy storage charging harness from bending due to its own gravity during the opening process, thereby causing the incision of the harness to be tilted and affecting the opening effect.

[0032] The end of the positioning plate 17 close to the first balancing retracting rod 13 is elastically connected to the inner cavity side wall of the shell 1 through a first spring, that is, the role of the positioning plate 17 through the elastic connection is only to make the lower end of the sleeve 19 fit closely with the surface of the wiring harness, and does not play a role in fixing the wiring harness. The lower end of the positioning plate 17 is rotatably connected with a plurality of symmetrical balls 18. When the energy storage charging harness is passed through the symmetrical clamping plates 5 during use, the positioning plate 17 will be lifted up due to the elastic connection when the energy storage charging harness passes through the distance between the symmetrical positioning plates 17, and automatically fits with the wiring harness surface. The outer skin of the wire harness is cut by rotating the handle 2 to drive the shell 1 to rotate 180°, and the outer skin of the wire harness is cut into pieces after the outer skin of the wire harness is cut. At this time, the outer shell 3 and the splint 5 clamp the wire harness and remain in a fixed state, and the outer shell 3 and the shell 1 are connected in rotation, that is, when the handle 2 and the shell 1 are rotated, the outer shell 3 and the wire harness remain in a fixed state, and the rotating ball 18 can facilitate the rotation of the shell 1 and the handle 2, thereby facilitating the cutting of the blade 34.

[0033] See also Figure 4-6The adjusting mechanism includes an extension rod 31, a follower block 32 is threadedly connected to the lower part of the extension rod 31, a follower plate 33 is rotatably connected to the lower end of the follower block 32, and the lower end of the follower plate 33 is fixedly connected to the upper end of the blade 34. The upper part of the extension rod 31 is vertically slidably connected to the follower rod 20, and the inner cavity of the lower end of the follower rod 20 is fixedly connected to a cross key 35. The outer wall of the extension rod 31 is provided with a cross groove 36 used to cooperate with the cross key 35, and the cross key 35 is slidably connected to the cross groove 36. The upper end of the follower rod 20 is fixedly connected to a first annular tooth 26, and the outer wall of the first annular tooth 26 is provided with a second gear 28. The inner cavity of the second gear 28 is engaged with the first annular tooth 26. The outer wall of the housing 1 is provided with a symmetrical second groove 7 and a symmetrical first groove 6, wherein the second groove 7 and the second gear 28 are located in the same vertical plane, and the tooth plate 22 is slidably connected in the first groove 6, and the tooth plate 22 and the second gear The wheels 28 are meshed, that is, the toothed plate 22 will drive the second gear 28 to rotate during the process of moving along the No. 1 slot 6 toward the direction of the handle 2. At this time, the second gear 28 will drive the driven rod 20 to rotate through the first annular tooth 26, thereby driving the extension rod 31 to rotate. Since the extension rod 31 is threadedly connected to the driven block 32, the driven block 32 is driven to move in the direction away from the first balancing retraction rod 13, thereby driving the blade 34 away from the first balancing retraction rod 13, that is, during the process of fixing the wiring harness, the blade 34 is located in the inner cavity of the sleeve 19 and does not contact the surface of the wiring harness, so that the extension length of the blade 34 can be adjusted according to the thickness of the wiring harness skin, thereby avoiding damage to the internal tissue of the wiring harness during the process of opening the wire, that is, by controlling the reciprocating movement of the toothed plate 22 in the No. 1 slot 6, the length of the blade 34 extending out of the sleeve 19 can be controlled, thereby adapting to wiring harnesses with skins of different thicknesses.

[0034] See also Figure 7-9When performing the wire cutting operation, it is common to perform a circular cut on the surface of the wire harness to cut and separate the rubber surface of the wire harness surface. Sometimes, it is necessary to completely remove the surface of the entire wire harness. At this time, the circular cutting operation cannot meet the demand, and it is necessary to perform a cross-cut on the surface of the wire harness to completely separate the internal tissue from the surface. When the wire harness is cross-cut, after one end of the wire harness passes through the interior of the shell 1, since the wire harness and the shell 1 need to move relative to each other in the horizontal direction during cross-cutting, it is not necessary to clamp and fix the wire harness by the clamping plate 5 at this time. The orientation of the blade 34 is different during circular cutting and cross-cutting, so it is necessary to align the blade under different operating conditions. The blade 34 needs to be adjusted by rotating the blade 34 to change the direction of the blade, that is, the driven plate 33 needs to be rotated. Both sides of the upper end of the driven plate 33 are fixedly connected with symmetrical connecting and contracting rods 27. One end of the connecting and contracting rod 27 away from the driven plate 33 is fixedly connected with a connecting plate 30. The connecting plate 30 is rotatably connected to the upper outer wall of the driven rod 20. The connecting plate 30 is located below the first annular tooth 26. The upper end of the connecting plate 30 is fixedly connected with a second annular tooth 29. The inner diameter of the first annular tooth 26 is smaller than the inner diameter of the second annular tooth 29, that is, the inner wall of the second annular tooth 29 does not contact the driven rod 20. When the angle of the blade 34 needs to be adjusted, It is necessary to separate the second gear 28 from the first annular gear 26 and engage the second gear 28 with the second annular gear 29, so that when the toothed plate 22 drives the second gear 28 to rotate, the second annular gear 29 can drive the connecting plate 30 to rotate, thereby driving the driven plate 33 to rotate through the connecting retracting rod 27, thereby changing the angle of the blade 34, and the upper end of the second gear 28 is rotatably connected to the ring 25, and the upper end of the ring 25 is fixedly connected to the U-shaped rod 24, and the middle part of the arc plate 21 is provided with an arc groove 23, and the side of the U-shaped rod 24 away from the ring 25 is slidably connected to the arc groove 23, that is, when the arc plate 21 moves along the second groove 7 toward the direction where the handle 2 is located, When the tooth plate 22 is moved, it will drive the arc groove 23 to move synchronously, thereby driving the U-shaped rod 24 to move in the direction of the connecting plate 30, and then driving the second gear 28 to move toward the connecting plate 30, and then moving the tooth plate 22 again can drive the second gear 28 to rotate, thereby changing the cutting edge direction of the blade 34, and the side wall of the driven plate 33 is fixedly connected with a symmetrical protrusion 43, and the lower part of the inner cavity of the housing 19 is provided with a rotating groove 44 that is centrally symmetrical about the center position of the driven plate 33 for use with the protrusion 43, and the rotating groove 44 is a 90° fan-shaped, that is, when adjusting the angle of the blade 34, the driven plate 33 will be blocked by the side wall of the rotating groove 44 after rotating 90° and cannot continue to rotate.

[0035] A symmetrical first slide groove 12 is provided on one side of the upper and lower ends of the handle 2. The first slide groove 12 and the No. 1 groove 6 are located in the same vertical plane. A first slider 9 is slidably connected to the inner cavity of the first slide groove 12. The end of the first slider 9 close to the shell 1 is connected to the middle of the end of the tooth plate 22 close to the handle 2 through a No. 1 rope 8. The end of the tooth plate 22 away from the No. 1 rope 8 is elastically connected to the side wall of the No. 1 groove 6 away from the handle 2 through a second spring. The upper and lower ends of the handle 2 are provided with a second slide groove 11 corresponding to the No. 2 groove 7. The inner cavity of the second slide groove 11 is slidably connected to the second slider 10. The end of the second slider 10 close to the shell 1 is connected to the arc plate 21 close to the handle 2 is connected by a No. 1 rope 8, and the end of the arc plate 21 away from the No. 1 rope 8 is elastically connected to the side wall of 7 away from the handle 2 by a third spring. By sliding the first slider 9, the toothed plate 22 can be driven by the No. 1 rope 8 to move along the No. 1 groove 6, thereby driving the blade 34 to extend out of the housing 19, and the second slider 10 can drive the arc plate 21 to move, thereby pushing the second gear 28 to fit with the connecting plate 30, thereby changing the angle of the blade 34, and when pulling the first slider 9 to continue to adjust the angle of the blade 34, it is only necessary to continue pulling the first slider 9 until it cannot move and then stop, at which time the blade 34 has just rotated 90°.

[0036] See also Fig.10, the tooth plate 22 and the arc plate 21 need to keep their positions fixed after moving to ensure that the extended length and angle of the blade 34 remain stable, that is, the first slider 9 and the second slider 10 need to keep their positions fixed after moving. A plurality of slots 38 are provided in the middle of the bottom wall of the inner cavity of the first slide 12 and the second slide 11. The plane where the upper end of the first slider 9 is located is higher than the plane where the upper end of the second slider 10 is located. The first slider 9 and the second slider 10 only differ in height, and the rest of the structures are the same. By symmetrically arranging the first slider 9 and the second slider 10, the first slider 9 and the second slider 10 on the upper and lower sides of the handle 2 can work independently. For example, when only the outer skin of one side of the wiring harness needs to be cross-cut, only one blade needs to be adjusted. The length and angle of 34 can be, and the other blade 34 can be located in the casing 19. The middle part of the upper end of the first slider 9 is rotatably connected with a rotating plate 40. A notch 41 is provided on the upper part of the first slider 9 near the side of the No. 1 rope 8. The notch 41 is located below the rotating plate 40. The notch 41 facilitates the rotation of the rotating plate 40. The middle part of the lower end of the first slider 9 is vertically slidably connected with a block 39. The upper end of the block 39 is connected to the lower end of the rotating plate 40 by a No. 2 rope 42. A groove for matching the block 39 is provided at the lower part of the first slider 9. The upper end of the block 39 is elastically connected to the top of the inner cavity of the groove by a fourth spring. The lower end of the block 39 is provided with an inclined surface. The vertical distance between the two ends of the inclined surface is greater than the inner cavity height of the slot 38. The block 39 is connected to the slot 38. 8, in the process of the first slider 9 moving away from the shell 1, the inclined surface is lifted up by the side wall of the slot 38, so that it shrinks into the slot. After the first slider 9 moves to a suitable position, the block 39 is re-engaged in the slot 38 to fix the first slider 9. When it is necessary to release the limit of the first slider 9, the rotating plate 40 is rotated and lifted, thereby driving the second rope 42 to move and causing the block 39 to shrink into the slot and separate from the slot 38. Under the elastic action of the second spring, the first slider 9 will automatically reset. Since the structure and function of the first slider 9 and the second slider 10 are the same, the movement and limit of the second slider 10 can be derived from the description of the first slider 9, and no further description is given here. Since the blade 34 will contact the wiring harness after extending out of the housing 19, at this time It is not convenient to adjust the angle, so it is necessary to adjust the blade 34 when it is in the sleeve shell 19, that is, first pull the second slider 10 to drive the arc plate 21 to move so that the second gear 28 is fitted with the connecting plate 30, and then pull the first slider 9 to rotate the blade 34 90°, release the limit of the second slider 10, and then pull the first slider 9 again to adjust the extension length of the blade 34. When the device is not working, make the second slider 10 away from the housing 1, even if the second gear 28 is in a position fitted with the connecting plate 30, it is convenient to adjust the angle of the blade 34. If there is no need to adjust the angle, then you only need to release the limit of the second slider 10 first, and then pull the first slider 9 to adjust the extension length of the blade 34.When the angle needs to be adjusted, the first slider 9 is first pulled to adjust the angle of the blade 34, and then the limit of the second slider 10 is released and the first slider 9 is pulled to adjust the extension length of the blade 34.
