Specifically, the suspension bracket 4 is fixed on the base 1 after crossing the sliding rail 5 and is fixed by a screw, and the suspension bracket 4 is lowered as shown in fig. 3. One end of the fixing cavity 9 close to the driving device extends into the suspension bracket 4, and the fixing cavity 9 can pass through the suspension bracket 4 under the driving of the driving device. The digital display thickness gauge 8 is hung in the middle of the transverse plate of the suspension bracket 4 through the telescopic rod 7, the digital display thickness gauge 8 is positioned at one end of the fixed cavity 9 close to the driving device, and the testing needle of the digital display thickness gauge 8 can be inserted into the strip-shaped detection port 15 of the fixed cavity 9 when the fixed cavity 9 moves towards the digital display thickness gauge 8.

Namely, if the thickness value displayed by the digital display thickness gauge 8 is changed continuously in the change of the contact point between the cable insulation layer and the testing needle contact of the digital display thickness gauge 8, the thickness value is not uniform, and the extrusion quality of the insulation layer is poor; if the thickness value displayed by the digital display thickness gauge 8 is kept consistent in the change of the contact point of the cable insulation layer and the testing needle contact of the digital display thickness gauge 8, the thickness of the cable insulation layer is uniform, and the extrusion thickness of the insulation layer is accurate.

At this time, the lifting adjusting nut 13 is screwed, so that the arc-shaped positioning plate 10 horizontally clamps the cable at the strip-shaped detection port 15 of the fixed cavity 9. At the moment, the length of the telescopic rod 7 is adjusted, so that a testing needle contact of the digital display thickness gauge 8 is in contact with the core surface of the guide core of the cable, and the reading of the digital display thickness gauge 8 is zero during contact. At the moment, the torque motor 2 is started through the control switch 17, the torque motor 2 drives the translation threaded rod 3 to rotate clockwise, the sliding block 6 moves towards the torque motor 2 under the rotation of the translation threaded rod 3, the fixed cavity 9 moves along with the sliding block 6, and the testing needle of the digital display thickness gauge 8 is in contact with the section of the cable insulation layer and swings towards the moving direction of the sliding block 6. At this time, the test needle contact of the digital display thickness gauge 8 is in sliding contact with the surface of the cable insulation layer, and at this time, the displayed data on the digital display thickness gauge 8 is the rear degree of the cable insulation layer. Along with the movement of the sliding block 6, the contact point of the cable insulation layer and the testing needle contact of the digital display thickness gauge 8 is changed, so that the digital display thickness gauge 8 can detect the whole thickness of the whole sampling cable insulation layer, and the accuracy of the insulation layer thickness of the sampling cable can be accurately obtained. Namely, if the thickness value displayed by the digital display thickness gauge 8 is changed continuously in the change of the contact point between the cable insulation layer and the testing needle contact of the digital display thickness gauge 8, the thickness value is not uniform, and the extrusion quality of the insulation layer is poor; if the thickness value displayed by the digital display thickness gauge 8 is kept consistent in the change of the contact point of the cable insulation layer and the testing needle contact of the digital display thickness gauge 8, the thickness of the cable insulation layer is uniform, and the extrusion thickness of the insulation layer is accurate.
The cable fixing mechanism can realize the integral fixation of the sampling cable, and meanwhile, the cable fixing mechanism is arranged on the sliding block 6 which is arranged on the sliding rail 5 and can slide along the sliding groove, so that the cable fixing mechanism can horizontally move under the driving of the arranged driving device, and the cable can pass through the digital display thickness gauge of the arranged cable thickness detection mechanism during the movement, so that the digital display thickness gauge 8 can detect the whole sampling cable insulating layer.
