Referring to fig. 1-6, the present invention provides the following technical solutions: special stripper of flexible mineral insulated cable metal sheath, which comprises a bracket 1, first drum 3 and second drum 4, mounting hole 2 has been seted up to the rear side of support 1, there is square frame 6 inside rear side of support 1 through 5 fixed mounting of connecting rod, the inside of square frame 6 is provided with two live-rollers 7, the middle part of two live-rollers 7 is all seted up flutedly 8, there are first fixed block 9 and second fixed block 10 on the rear side upper portion from the top down of square frame 6 fixed mounting in proper order, threaded rod 19 is run through to the inside of first fixed block 9, the bottom of threaded rod 19 is rotated with the top of second fixed block 10 and is connected, the week side cover of threaded rod 19 is equipped with screw plate 11, the front side of screw plate 11 and the preceding of square frame 6 move sideslip and be connected, the bottom of screw plate 11 is provided with cutterbar 12, first drum 3 and second drum 4 all cooperate with mounting hole 2, first drum 3 and second drum 4 all pass through the rear side fixed connection of bolt and support 1, the internal rotation of first drum 3 has drum screw thread section of drum 13, the inside fixed mounting of second drum 4 has circle cover 14.

Wherein the middle upper surface of support 1 is provided with steel wire 15, and during the use, pass the upper portion of steel wire 15 with the cable, make the shell after the cutting pass the lower part of steel wire 15, pull cable and shell simultaneously, make shell and cable separation.

Wherein the front side of support 1 is provided with solid fixed cylinder 16, and the inside front side of solid fixed cylinder 16 is provided with spacing section of thick bamboo 17, and spacing section of thick bamboo 17 is removable, makes the cable laminate more, reduces the shake of cable, and the stability that keeps moving improves the cutting.

Wherein the top of the threaded rod 19 is provided with a turning handle 18.

Wherein the outer material of the rotating roller 7 is rubber.

Wherein the central axes of the mounting hole 2 and the recess 8 coincide.

During the use, can change according to the form of sheath, when the sheath is the spiral sheath, adopt first drum 3, fix first drum 3 in the inside of mounting hole 2 through the bolt, the inside screw thread section of thick bamboo 13 of first drum 3 and the outside cooperation of spiral sheath, when the spiral sheath removes, screw thread section of thick bamboo 13 is driven the spiral sheath and is rotated, such design makes spiral sheath and screw thread section of thick bamboo 13 zonulae occludens, prevent that the sheath is not hard up, when the sheath is smooth pipe, adopt second drum 4, guarantee with the laminating nature of sheath, guarantee the accuracy of cutting.

The cutter 12 comprises a cutter seat and a cutter 21, the cutter seat is fixedly connected with the thread plate 11, and the middle part of the cutter 21 is connected with the cutter seat through a rotating shaft 20. The connecting mode of the rotating shaft can enable the cutter to automatically adjust the angle of the cutter according to the change of stress along with the rotation of the metal sheath, and finally the cutter is more labor-saving in the cutting process, and the cutting surface is smoother. Preferably, the bottom of the part of the cutter above the rotating shaft is flat and has no cutting edge, and the bottom of the part of the cutter below the rotating shaft has a cutting edge. Further preferably, the portion of the cutter located below the rotating shaft is thinner in thickness closer to the rotating roller 7, forming a blade. The rotating shaft is equal to the fulcrum of the lever, and the part without the blade is pressed on the cutter seat to provide supporting force for the part with the blade. Preferably, the second scheme includes that the rotating shaft is connected with a motor rotating shaft, the motor rotating shaft drives the rotating shaft to rotate, and the rotating shaft drives the cutter to rotate, so that the cutting angle of the cutter is controlled. Preferably, when the second cylinder 4 is used, the motor drives the cutter to make an angle between the extending direction of the cutting edge of the cutter and the central axis of the metal sheath less than 5 degrees to complete the axial cutting, and then drives the cutter to make an angle between the extending direction of the cutting edge of the cutter and the central axis of the metal sheath 87 degrees to 90 degrees to complete the radial cutting. When the first cylinder 3 is used, the motor drives the cutter to the same extending direction of the cutting edge of the cutter as the spiral direction of the thread of the metal sheath to complete axial cutting, and then drives the cutter to the same extending direction of the cutting edge of the cutter as the angle of 87-90 degrees with the central axis of the metal sheath to complete radial cutting. In order to facilitate the sleeving of the second cylinder 4 and the first cylinder 3 on the cable, the second cylinder 4 and the first cylinder 3 are preferably each made by splitting two sub-parts. Therefore, the two sub-parts are buckled on the cable respectively, then the two sub-parts are fixed together, and the two sub-parts can be fixed through the flange or limited together through the mounting hole 2. The motor can be arranged, the motor can also not be arranged, under the condition that the motor is not arranged, a through hole can be arranged on the part, above the rotating shaft, of the cutter, a blind hole is arranged on the cutter seat, the position of the cutter is adjusted manually to align the through hole with the required blind hole, and then a limiting bolt is inserted into the through hole and the blind hole to fix the position of the cutter. Through rationally setting up the blind hole, can play the effect of adjustment and restriction cutter position equally. The number of the through holes is less than one, preferably two, and a gap is formed between the two through holes, so that the distance of the limiting bolt is pulled open by the two through holes, the stress of the limiting bolt is dispersed, and the whole structure is firmer. The end of the part of the cutter below the rotating shaft is provided with a hook 22 bent to the rotating roller 7, and the hook 22 is utilized to pierce the metal sheath and generate pulling force on the basis of cutting, so that axial cutting is more easily completed. The hook is also preferably provided with a blade. Preferably, a cutting edge is arranged on one side, facing the rotating shaft, of the hook, a groove with a downward opening is formed in one side, facing the rotating roller 7, of the hook, an electric heating wire is arranged in the groove, the electric heating wire leaks out of a notch of the groove, a side groove is formed in one side, far away from the rotating roller 7, of the cutter, and the electric heating wire penetrates through the side groove and is connected to the power supply module. So that the plastic or rubber part outside the metal sheath is melted away using the heating wire. The bottom of the part of the knife located below the axis of rotation preferably extends first away from the rotating roller and then towards the rotating roller 7. Thereby forming an inclined plane and using the inclined plane to pierce the metal sheath more conveniently. Meanwhile, the metal sheath is turned outwards by the inclined plane.
