[0029] The following is combined with Figure 1-Figure 9 The present invention is described in further detail.

[0030] The embodiment of the present invention discloses a wire cutter for network engineering wiring. Figure 1-Figure 9 As shown, it includes a wire feeding wheel 1 and a main frame 2. The wire feeding wheel 1 is damped and installed at the left end of the main frame 2. When the wire is pulled out from the surface of the wire feeding wheel 1, the wire feeding wheel 1 generates resistance to the pulling out of the wire to ensure that the pulled wire remains straight. A double-rod top frame 3 is fixed above the main frame 2. Two movable side rods 4 are arranged between the double-rod top frame 3 and the main frame 2. Each movable side rod 4 is slidably connected to the double-rod top frame 3. A two-way threaded shaft 5 is penetrated through the front rotation of the double-rod top frame 3. The two movable side rods 4 are respectively threadedly sleeved on the two ends of the two-way threaded shaft 5. When the two-way threaded shaft 5 rotates forwards and backwards, the two movable side rods 4 can be driven to approach or move away from each other respectively. A plurality of fixed plates 6 are arranged between the double-rod top frame 3 and the main frame 2, and the ends of each two adjacent fixed plates 6 that are away from each other are respectively installed on the bottom surfaces of the two movable side rods 4.

[0032] The cutting structure 7 includes a block 71, the upper surface of the block 71 is fixed to the bottom surface of the adjacent fixed plate 6, and a double arc groove 75 is provided on one side of the block 71 close to the center line of the double-pole top frame 3. When the block 71 moves under the double-pole top frame 3, the wire will enter the double arc groove 75, and then when the block 71 moves with the movable side rod 4, the wire is gradually pulled into a curved wave shape. The two movable side rods 4 move synchronously, driving the length of the wire between the two adjacent blocks 71 to be the same. A vertical groove 74 is provided on one side of the block 71 close to the center of the double-pole top frame 3, and a cutting knife 72 is slidably inserted inside the vertical groove 74 to cut. A vertical edge rod 73 is fixed to the upper surface of the knife 72, and the upper end of the vertical edge rod 73 slides through the adjacent blocks 71 and the fixed plate 6 in sequence. The upper end of the vertical edge rod 73 is elastically connected to the connected fixed plate 6. Pressing plates 27 are provided on the front and rear sides of the double-rod top frame 3. The upper surfaces of the two pressing plates 27 are fixed by the bent frame 20. The bottom surface of the bent frame 20 is fixed with a power telescopic rod 19. The lower end of the power telescopic rod 19 is fixed to the upper surface of the double-rod top frame 3. When the pressing plate 27 moves downward by applying pressure to the vertical edge rod 73, the vertical edge rod 73 drives the cutting knife 72 to move downward to cut off the line in the double arc groove 75.

[0033] The bottom surface of the block 71 and the left and right sides of the cutting knife 72 are detachably mounted with an inner cavity plate 21, and one side of the inner cavity plate 21 close to the center of the double-rod top frame 3 is provided with an opening adapted to the double arc groove 75, and a double-sided toothed plate 22 is arranged inside the inner cavity plate 21, and the double-sided toothed plate 22 is elastically connected to the inside of the inner cavity plate 21, and the upper and lower sides of the double-sided toothed plate 22 are meshed with a torsion gear 23, and the torsion gear 23 is rotatably connected to the inner cavity plate 21, and the outer surface of the torsion gear 23 is fixed The skin cutting knife 24 is fixedly connected, and the two skin cutting knives 24 located inside the same inner cavity plate 21 are respectively located at the upper and lower sides of the opening of the inner cavity plate 21. The sides of the two skin cutting knives 24 located in the same inner cavity plate 21 that are close to each other are both semi-circular cutting knife-shaped structures. The upper end of the prism elastic telescopic rod 26 is located below the upper end of the vertical edge rod 73. The lower end of the cutting knife 72 is close to the connected block 71. The side is an inclined surface, and an inclined pusher is arranged above the end of the double-sided tooth plate 22 close to the double-rod top frame 3. The upper surface of the plate 25 and the inclined push plate 25 are fixed with a prismatic elastic telescopic rod 26. The upper end of the inner cavity plate 21 is slidably sleeved on the outer surface of the prismatic elastic telescopic rod 26 with the block 71. The upper end of the prismatic elastic telescopic rod 26 slides through the bottom surface of the fixed plate 6, and the pressing plate 27 moves downward and first contacts with the upper end of the prismatic elastic telescopic rod 26, pushing the inclined push plate 25 to move downward and pushing the double-sided toothed plate 22 to move. The torque gear 23 engages with the moving double-sided toothed plate 22 to drive the skin cutting knife 24 to approach the line. When the two skin cutting knives 24 merge, the skin cutting knife 24 will cut off the outer skin of the lines on both sides, and then when the pressing plate 27 continues to move downward, the prismatic elastic telescopic rod 26 is compressed, and then the pressing plate 27 pushes the vertical ridge rod 73 downward to drive the cutting knife 72 to cut the line. The disconnected position of the line can remove the cut outer skin of the line, and the inner cavity plate 21 is detachable. By replacing the inner skin cutting knife 24 with different semi-ring parameters, the outer skin of lines of different diameters can be cut.

[0034] A positioning stop rod 8 is provided on the right side of the rightmost fixed plate 6 among the multiple fixed plates 6, and the positioning stop rod 8 is unidirectionally elastically rotatably connected to one of the movable side rods 4. The positioning stop rod 8 and the adjacent fixed plate 6 are respectively installed and connected to two movable side rods 4. The connection between the movable side rod 4 and the adjacent positioning stop rod 8 is set to a U-shaped open groove, and the two movable side rods 4 are symmetrically distributed front and back about the axis of the double-rod top frame 3.

[0035] Two longitudinal wheels 9 are arranged between the wire feeding wheel 1 and the double-pole top frame 3 and above the main frame 2. The two longitudinal wheels 9 are both rotatably connected to the left end of the double-pole top frame 3. Two vertical wheels 10 are arranged on the right side of the two longitudinal wheels 9. The two vertical wheels 10 are both rotatably connected to the left end of the double-pole top frame 3. The wire passes between the two longitudinal wheels 9 and the two vertical wheels 10. The position of the wire is limited. An active movable bar 11 is arranged on the left side of the double-pole top frame 3. The active movable bar 11 is located on the right side of the two vertical wheels 10. The active movable bar 11 is slidably plugged into the upper surface of the main frame 2. The right side of the active movable bar 11 is arranged There is a driven movable bar 14, and two positioning elastic telescopic rods 12 are fixed to the right side of the active movable bar 11. The other end of the positioning elastic telescopic rod 12 is fixed to the driven movable bar 14. The positioning elastic telescopic rod 12 has a tendency to push the driven movable bar 14 away from the active movable bar 11. A one-way threaded shaft 13 is arranged below the driven movable bar 14. The two ends of the one-way threaded shaft 13 are respectively rotatably connected to the two ends of the main frame 2. The lower end of the active movable bar 11 is threadedly sleeved on the outer surface of the one-way threaded shaft 13. The one-way threaded shaft 13 can drive the active movable bar 11 to move left and right by rotating forward and backward.

[0036] A wire clamping structure 18 is arranged on the right side of the driven movable bar 14, and a one-way threaded rod 15 is arranged above the driven movable bar 14. The rear end of the one-way threaded rod 15 is connected to the wire clamping structure 18, and the driven movable bar 14 is rotatably sleeved on the outer surface of the one-way threaded rod 15. Two tooth grooves 28 are arranged on the upper surface of the main frame 2, and an elastic damping plate 29 is meshed inside the tooth grooves 28. The upper end of the elastic damping plate 29 is fixed to the bottom surface of the driven movable bar 14. When the driven movable bar 14 moves with the active movable bar 11, the tooth structure of the tooth groove 28 continuously applies resistance to the elastic damping plate 29. When the active movable bar 11 moves to the left, the active movable bar 11 moves away from the driven movable bar 14. When the active movable bar 11 moves to the right, the driven movable bar 14 gradually approaches the active movable bar 11 under the resistance of the tooth groove 28 to the elastic damping plate 29.

[0037] One end of the one-way threaded rod 15 located in front of the driven movable bar 14 is threadedly sleeved with a threaded gear 16, and the threaded gear 16 is rotatably connected to the front of the driven movable bar 14. An adjusting tooth plate 17 is tangentially arranged above the threaded gear 16. The adjusting tooth plate 17 is located on the right side of the double-rod top frame 3. The adjusting tooth plate 17 is elastically connected to the right end of the double-rod top frame 3. The wire clamping structure 18 includes a groove bar 181 and two wire clamping rods 182. The front end of the groove bar 181 is fixed to the rear end of the one-way threaded rod 15, and the upper surface of the groove bar 181 is groove-shaped. The groove-shaped structure of the groove bar 181 is rotatably installed with a bidirectional threaded rod 183. The lower ends of the two wire clamping rods 182 are respectively threadedly sleeved on the two ends of the bidirectional threaded rod 183. When the threaded gear 16 is engaged with the adjusting tooth plate 17, rotation is generated, and the threaded gear 1 6 pushes the groove bar 181 backward by meshing with the one-way threaded rod 15, and stops moving backward when the clamping rod 182 contacts the positioning stop rod 8, so that the distance between the thread head and the adjacent cutting structure 7 is equal to the distance between the two adjacent cutting structures 7, ensuring that the length of the thread head cut out is the same as the length of the thread cut at the middle position. The middle position of the two-way threaded rod 183 is rotatably sleeved with a wire support frame 187, the lower end of the wire support frame 187 is fixed to the groove bar 181, and the upper end of the wire support frame 187 is T-shaped. The upper ends of the two clamping rods 182 are slidably sleeved on the front and rear ends of the wire support frame 187, and the wire passes through the top of the wire support frame 187. When the two clamping rods 182 are close to each other, the height of the wire is fixed, so that when the block 71 moves, the taut wire can move into the double arc groove 75.

[0038] An inner prism shaft 184 is fixed to the front end of the bidirectional threaded rod 183, and a synchronous gear 185 is slidably sleeved on the outer surface of the inner prism shaft 184. The front end of the driven movable bar 14 is rotatably sleeved on the rear end of the synchronous gear 185, and an offset tooth plate 186 is meshed below the synchronous gear 185. The left end of the offset tooth plate 186 is fixed to the front end of the active movable bar 11. When the active movable bar 11 moves to the right, the tooth groove 28 applies resistance to the elastic damping plate 29 and the driven movable bar 14, so that the active movable bar 11 first approaches the driven movable bar 14 relatively when moving to the right, driving the offset tooth plate 186 to mesh with the synchronous gear 185 to rotate the inner prism shaft 184 and the bidirectional threaded rod 183, and the two clamping rods 182 are meshed with the bidirectional threaded rod 183 to approach each other and clamp the thread head.

[0039] The working principle is as follows: the wire to be cut is wound onto the surface of the wire feeding wheel 1, and the one-way threaded shaft 13 is rotated to mesh with the active movable bar 11 and move to the left, driving the clamping rod 182 to move to the right side of the vertical wheel 10, pulling the wire end through between the two longitudinal wheels 9 and the two vertical wheels 10, and then when the active movable bar 11 moves to the right, the tooth groove 28 applies resistance to the elastic damping plate 29 and the driven movable bar 14, so that the active movable bar 11 first moves relatively close to the driven movable bar 14 when moving to the right, driving the misaligned tooth plate 186 to mesh with the synchronous gear 185 to rotate the inner prism shaft 184 and the bidirectional threaded rod 183, and the two clamping rods 182 are engaged with the bidirectional threaded rod 183. The threaded rods 183 mesh with each other and approach each other to clamp the thread head. Then, when the active movable bar 11 continues to move to the right, the thread head line is pulled to continuously pass between the front and rear rows of blocks 71. Then, the bidirectional threaded shaft 5 is controlled to rotate and mesh with the movable side rod 4, driving the two rows of blocks 71 to move away from the double-rod top frame 3 after approaching the double-rod top frame 3. After pulling the corresponding blocks 71 in contact with the line, the line is pulled gradually into a bent and wavy shape. When the line contacts the blocks 71, it is located in the double arc groove 75 and stops moving after the two movable side rods 4 move the required distance. When cutting, the pressure plate 27 is controlled to move downward and push the cutting knife 72 downward by pushing the vertical edge rod 73 to cut the line.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
