Since the thread directions at both ends of the screw 601 are opposite, the screw 601 thread drives the two second sliders 602 to move in opposite directions, thereby quickly adjusting the distance between the two second sliders 602, and then the two third sliders 603 can fix cables of different diameters, which increases the flexibility and applicability of the detection device.

[0025] As a technical optimization solution of the utility model, two third guide rods 606 are fixedly connected to the second clamp 305, and two adjacent second sliders 602 are slidably connected to the same third guide rod 606. The second slider 602 is fixedly connected to the second guide rod 605, and the third slider 603 is slidably connected to the second guide rod 605; the setting of the second guide rod 605 and the third guide rod 606 respectively guides the third slider 603 and the second slider 602, thereby increasing the stability of the movement of the third slider 603 and the second slider 602.

[0026] As a technical optimization solution of the utility model, the driving structure 2 includes two slide rails 201, and the operating table 1 is fixedly connected with two slide rails 201, one of which is rotatably connected with a screw rod 203, and the other slide rail 201 is fixedly connected with a first guide rod 204, a first slider 205 is threadedly connected to the screw rod 203, and another first slider 205 is slidably connected to the first guide rod 204, and the two first sliders 205 are fixedly connected with the same mounting rod 202, and the detection structure 3 is installed at the bottom end of the mounting rod 202, and the operating table 1 is fixedly connected with the first slider 205.

[0027] As a technical optimization solution of the utility model, a pressure sensor 301 is installed at the bottom end of the mounting rod 202, a connecting sleeve 302 is installed at the bottom end of the pressure sensor 301, a first clamp 303 is threadedly connected to the bottom end of the connecting sleeve 302, a first roller 304 is rotatably connected to the first clamp 303, two second rollers 306 are rotatably connected to the second clamp 305, the two second rollers 306 are symmetrically distributed about the middle of the second clamp 305, a cable is installed in the groove of the second roller 306, and the first roller 304 is in conflict with the top surface of the cable; when both ends of the cable are fixed on the fixed structure 6, the cable slides into the grooves of the two second rollers 306 synchronously, and then passes through the mounting rod 202 The movement drives the pressure sensor 301, the connecting sleeve 302, the first clamp 303 and the first roller 304 to move downward, and the first roller 304 contacts the cable downward, and the cable is bent and deformed by continuously applying pressure to the cable. The setting of the first roller 304 and the two second rollers 306 has a guiding effect on the cable. When the driving structure 2 drives the first roller 304 to apply pressure to the cable, the cable contacts the first roller 304 and the two second rollers 306 and drives the three rollers to rotate, thereby reducing the friction between the cable and the test data, thereby making the test data more accurate. Then the pressure sensor 301 detects the pressure on the cable through the reverse force of the cable on the first roller 304, and then transmits it to the computer end to obtain the test data.

[0028] As a technical optimization scheme of the utility model, a knob 8 is rotatably connected to the mounting seat 5, and the end of the knob 8 is threadedly connected to the connecting rod 7.

[0029] When the utility model is in use, the cable is first pressed downward from the top of the fixed structure 6, so that the two ends of the cable are respectively engaged between the two adjacent third sliders 603. During the movement, the cable resists the two third sliders 603 and slides to both sides respectively. The third slider 603 drives the spring 604 to contract, so that the third slider 603 performs preliminary fixing of the cable, avoiding horizontal displacement of the cable and increasing the stability of the cable. At the same time, the sliding of the third slider 603 and the elastic deformation of the spring 604 allow the cable to have vertical sliding space under the pressure of the detection structure 3, preventing the third slider 603 from interfering with the testing work of the detection structure 3 on the cable. When it is necessary When testing cables of different diameters, the rotating rod 607 is rotated, and the rotating rod 607 drives the screw 601 to rotate. Since the threads at both ends of the screw 601 are in opposite directions, the threads of the screw 601 drive the two second sliders 602 to move in opposite directions, so that the distance between the two second sliders 602 can be quickly adjusted, and the two third sliders 603 can be fixed to cables of different diameters, thereby increasing the flexibility and applicability of the detection device; the second guide rod 605 and the third guide rod 606 are respectively provided to guide the third slider 603 and the second slider 602, thereby increasing the stability of the movement of the third slider 603 and the second slider 602 When both ends of the cable are fixed on the fixed structure 6, the cable synchronously slides into the grooves of the two second rollers 306, and then the motor 206 is started, the motor 206 drives the screw rod 203 to rotate, the screw rod 203 thread drives the first slider 205 to slide downward, the first slider 205 drives the installation rod 202 to move downward, and at the same time, the installation rod 202 drives the first slider 205 on the first guide rod 204 to slide, and the installation rod 202 is driven to move by the two first sliders 205 sliding in the slide rail 201, so that the movement of the installation rod 202 is more stable; when the installation rod 202 moves, it drives the first The roller 304 moves downward, and the first roller 304 contacts the cable downward, and the cable is bent and deformed by continuously applying pressure to the cable. The first roller 304 and the two second rollers 306 are arranged to guide the cable. When the driving structure 2 drives the first roller 304 to apply pressure to the cable, the cable contacts the first roller 304 and the two second rollers 306, and then drives the three rollers to rotate, thereby reducing the friction between the cable and the cable, thereby making the test data more accurate. Then, the pressure sensor 301 detects the pressure on the cable through the reverse force of the cable on the first roller 304, and then transmits it to the computer end, thereby obtaining the test data;The setting of the connecting sleeve 302 facilitates the installation and removal of the first clamp 303, and facilitates the replacement of the first clamp 303 with different structures; when installing the second clamp 305, the connecting rod 7 at the bottom of the second clamp 305 is engaged with the mounting seat 5, and then the knob 8 is turned to make the end of the knob 8 threadedly connected with the connecting rod 7, so as to quickly complete the installation of the second clamp 305, thereby facilitating the installation and removal of the second clamp 305. ;
