[0036] A horizontal plate is fixed between the tops of the first vertical plate and the second vertical plate, and an adjusting mechanism is arranged at the top of the horizontal plate. The adjusting mechanism includes a driving assembly 9 and two push rods 10. The driving assembly 9 is arranged at the top of the horizontal plate. The two push rods 10 are arranged on the driving assembly 9, and each push rod 10 is in conflict with an insertion rod 5. The winding assembly 2, the rotating assembly 8 and the driving assembly 9 are all electrically connected to the controller.

[0037] Reference Figures 1 to 6As shown, the winding assembly 2 includes a winding roller 11, a first motor 12 and a first rotating shaft 13. The first motor 12 is inserted on the outer wall of the second vertical plate, and the first rotating shaft 13 is rotatably arranged on the second vertical plate. The winding roller 11 is fixedly arranged on the first rotating shaft 13, and the first rotating shaft 13 is fixedly connected to the output end of the first motor 12. A conveying hole 14 for the cable to pass through is opened on the top of the third vertical plate. The first motor 12 is electrically connected to the controller. When the cable defect detection is performed, the processed cable is firstly rolled onto the outer wall of the unwinding roller 1, and then the free end thereof passes through the tensioning wheel 6 on the left and passes through the conveying hole 14, and then the controller is started. The industrial camera 7 and the rotating assembly 8 are driven to rotate the industrial camera 7 to detect defects in the insulation layer of the cable. At the same time, the cable is manually pulled horizontally to the right until the insulation layer of the free end of the cable is detected. Then, it passes through another tensioning wheel 6 and is wound onto the outer wall of the winding roller 11 and fixed. Then, the first motor 12 is started through the controller. Since its output end is fixedly connected to the winding roller 11 through a rotating shaft, the rotating shaft is rotatably connected to the second vertical plate, thereby causing the winding roller 11 to rotate, and the cable delivered from the delivery hole 14 after detection is wound onto the outer wall of the winding roller 11, thereby realizing automatic material collection and avoiding manual collection.

[0038] Reference Figures 1 to 6 As shown, the rotating assembly 8 includes a second motor 15, a first gear 16 and a ring gear 17.

[0039] Reference Figures 1 to 6As shown, the driving assembly 9 includes a bidirectional electric push rod 18, two racks 19, two second gears 20 and two second rotating shafts 21. The two second rotating shafts 21 are rotatably arranged on the first vertical plate and the second vertical plate respectively.

Each rack 19 is slidably arranged on the top of the horizontal plate through a slide rail 22. The two output ends of the bidirectional electric push rod 18 pass through the two slide rails 22 and are fixedly connected to one end of the two racks 19 respectively. Each second gear 20 is fixed on a second rotating shaft 21. Each rack 19 is meshed with a second gear 20. The bidirectional electric push rod 18 is electrically connected to the controller. When the cracks in the insulation layer of the cable are not obvious, the bidirectional electric push rod 18 is started by the controller, so that its two output ends are extended outward. Since each output end is connected to a rack 19 is fixedly connected, each rack 19 is slidably connected to a slide rail 22, so that each rack 19 slides inside a slide rail 22 toward one end away from the two-way electric push rod 18. In addition, the two second gears 20 are fixedly connected to the two second rotating shafts 21, and each rack 19 is meshed with a second gear 20. Each push rod 10 is fixedly connected to a second rotating shaft 21 through a pipe clamp, and each push rod 10 is in contact with a plug rod 5, so that the two push rods 10 rotate from bottom to top to contact the plug rod 5. Since each plug rod 5 is fixedly connected to the inner ring of a bearing 4, and each bearing 4 is fixedly connected to a slider 3, each slider 3 is driven to slide up inside a slide groove, and further drives the tensioning wheel 6 on the plug rod 5 to rise, so as to increase the tensioning force of the entire cable, making the crack more obvious, so that the industrial camera 7 can take a clearer picture of the crack.

[0040] Reference Figures 1 to 6 As shown, a stopper 23 is fixedly provided at one end of each push rod 10 away from the second rotating shaft 21. The stopper 23 plays a limiting role when the push rod 10 rotates, and is also helpful to enhance the resistance force of the push rod 10 degree insertion rod 5, thereby enhancing the lifting effect of the tensioner wheel 6.

[0041] Reference Figures 1 to 6 As shown, two return springs 24 are fixedly provided between the inner top of each slide groove and the top of a slider 3. When the slider 3 slides up, the two return springs 24 are forced to contract and play a buffering role, ensuring that the two tensioning wheels 6 rise slowly to prevent the cables from being directly torn. When the slider 3 is reset, the two return springs 24 are reset to the initial state to ensure the next adjustment effect.
