[0026] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a data cable cutting device, comprising two symmetrically arranged housings 302, a reset slide rod 301 fixedly mounted on one housing 302, the reset slide rod 301 slidingly engaging with the other housing 302, a reset tension spring 303 surrounding the reset slide rod 301, the two ends of the reset tension spring 303 being fixedly connected to the two housings 302 respectively, and a handle 304 fixedly mounted on each of the two housings 302.

A pressing strip 102 is slidably mounted on the fixed platform 103. One end of the pressing strip 102 is fixed with a rod-shaped fixing claw 101. An electric cylinder 106 is also fixedly mounted on one of the fixed platforms 103. A connecting frame 108 is fixedly mounted on the end of the telescopic rod of the electric cylinder 106. A hook part 1081 and an insertion part 1082 are fixedly provided on the connecting frame 108. A pre-loaded part is fixedly installed between the fixed platform 103 and the fixing claw 101. A compression spring 104 and a pre-compression spring 104 are wrapped around the extrusion bar 102. The extrusion bar 102 is provided with reverse teeth. The feed pin 109 is in contact with the reverse teeth. A sliding plate 105 is also fixedly installed on the fixed table 103. The sliding plate 105 is provided with two slide rails.

A locking plate 110 is also fixedly installed on the outer shell 302. One end of the locking plate 110 is provided with a through hole. The through hole is inserted into the insertion part 1082.

[0027] like Figures 3-7As shown, it also includes a cutting assembly, which includes two semi-circular gear ring brackets 201 respectively fixedly installed inside the two fixed tables 103. Each semi-circular gear ring bracket 201 is provided with a semi-circular gear ring 202. A movable gear 204 is engaged with the semi-circular gear ring 202. The movable gear 204 is rotatably mounted on a movable support plate 203, which is movably engaged with the semi-circular gear ring 202. A cutting worktable 209 is fixedly installed on the movable support plate 203. A lead screw 208 is movably installed on the cutting worktable 209. A blade 206 is fixedly installed at one end of the lead screw 208. The blade 206 interacts with the cutting worktable 209. An elastic component 207 is provided between 09 and 08. The other end of the lead screw 208 is slidably engaged with a free bevel gear 216 via a spline. The free bevel gear 216 engages with a conical rack 217. A first movable threaded block 213 and a second movable threaded block 214 are also slidably mounted on the cutting table 209. Both the first movable threaded block 213 and the second movable threaded block 214 are movably connected to both ends of a central rocker arm 212 via a linkage rocker arm 211. The central rocker arm 212 is rotatably mounted on the cutting table 209 via a central rocker arm bracket 210. The first movable threaded block 213 and the second movable threaded block 214 are threaded with the lead screw 208. In a coordinated manner, the movable gear 204 is fixedly mounted on the output shaft of the movable motor 205, which is fixedly mounted on the movable support plate 203. The conical rack 217 is fixedly mounted on the rack bracket 218, which is fixedly mounted on the outer casing 302. A lead screw bracket 215 is also fixedly mounted on the cutting worktable 209, and the lead screw bracket 215 is movably connected to the lead screw 208. The central rocker arm 212 is rotatably engaged with the central rocker arm bracket 210, which is fixedly connected to the cutting worktable 209. A pull rod support plate 224 is fixedly mounted on the cutting worktable 209, and the pull rod support plate 224 slides on the pull rod support plate 224. A pull rod 225 is connected, and a drive plate 222 and a hook plate 226 are fixedly connected to both ends of the pull rod 225 respectively. The drive plate 222 is fixedly connected to the first moving threaded block 213. The pull rod support plate 224 is in contact with the hook part 1081. A drive spring 223 is fixedly provided between the drive plate 222 and the pull rod support plate 224. The drive spring 223 surrounds the pull rod 225. A tension wheel bracket 219 is fixedly installed on the extrusion strip 102. A tension motor 221 is fixedly installed on the tension wheel bracket 219. A tension wheel 220 is fixedly installed on the output shaft of the tension motor 221. The tension wheel 220 is in frictional contact with the surface of the data cable 4.

[0028] The working principle of the data cable cutting device disclosed in this invention is as follows: During use, hold both handles 304 and pull apart the two outer shells 302. Pass the data cable 4 through the middle of the two outer shells 302 and through the two tensioning wheels 220, placing one end between the two fixing claws 101. Then release the handles 304, causing the two outer shells 302 to press against each other under the action of the return spring 303. At this time, the two fixing claws 101 will clamp the data cable 4, and simultaneously, the preload spring 104... Under the action of the two fixed claws 101, the data cable 4 will be pre-clamped. Then, the extension of the electric cylinder 106 is controlled. The telescopic rod of the electric cylinder 106 will drive the connecting frame 108 to move. The connecting frame 108 will drive the feed pin 109 to move through the L-shaped connecting rod 107. The feed pin 109 will move along the slide rail of the sliding plate 105, so that it contacts the reverse teeth on the extrusion bar 102. Then, the extrusion bar 102 will move together with the feed pin 109. At this time, the data cable 4 will be clamped between the two fixed claws 101.

[0029] When the two outer casings 302 are closed, the two tensioning rollers 220 will also come into contact with the data cable 4. Next, the two tensioning motors 221 are activated, and the two tensioning motors 221 drive the tensioning rollers 220 to rotate in opposite directions, so that the data cable 4 between the fixing claw 101 and the tensioning rollers 220 is in a taut state. During cutting, the movable motor 205 is activated. The output shaft of the movable motor 205 drives the movable gear 204 to rotate. The rotation of the movable gear 204 causes the movable support plate 203 and the components on the movable support plate 203 to rotate together on the semi-circular gear ring 202 (the semi-circular gear ring 202 is equipped with a slide rail, and the movable support plate 203 is slidably installed in the slide rail). The rotation of the movable support plate 203 causes the cutting worktable 209 to rotate. The rotation of the cutting worktable 209 causes the first movable threaded block 213 and the second movable threaded block 214 to rotate. Since the movement of the connecting frame 108 has already caused the hook plate 226 to separate from the hook pull part 1081, under the action of the drive spring 223, the first movable threaded block 213 will move towards one side of the lead screw 208 and through the linkage rocker arm 211 The action of the central rocker arm 212 brings the first movable threaded block 213 and the second movable threaded block 214 closer together and threadedly connected to the lead screw 208. When the free bevel gear 216 revolves, the conical rack 217 drives the free bevel gear 216 to rotate, which in turn drives the lead screw 208 to move vertically. The movement of the elastic component 207 drives the blade 206 to move. At this time, the blade 206 moves closer to one side of the data cable 4, thereby cutting into the outer sheath of the data cable 4. Therefore, every time the free bevel gear 216 revolves, the engagement position with the conical rack 217 drives the lead screw 208 to move, further allowing the blade 206 to cut into the outer sheath of the data cable 4, preventing a one-time cut into the data cable 4 and causing damage to the inner cable sheath. Furthermore, when the insertion part 1082 is inserted into the locking plate 110, it can prevent the two outer shells 302 from accidentally separating.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
