The automatic cable tensile strength detector according to claim 5, further comprising a telescopic rod, wherein one end of the telescopic rod is fixedly connected with the second ring of the movable clamping member, and the other end of the telescopic rod is fixedly connected with the second ring of the fixed clamping member.
7. The automatic cable tensile strength tester according to claim 1, wherein the conveying assembly comprises:
the two connecting rods are fixedly connected with the two clamping parts which slide in a collinear way on the fixed clamping piece in a one-to-one correspondence manner;
the two conveying wheels are respectively connected with one connecting rod in a rotating mode, rotating shafts of the two conveying wheels are parallel, and the two conveying wheels are symmetrical about the axis of the first circular ring;
two gears, each of which is coaxially and fixedly connected with one of the conveying wheels;
the third driving unit is used for driving any one conveying wheel to rotate;
when the clamping parts on the fixed clamping piece synchronously slide away from the center of the first circular ring, the two conveying wheels synchronously slide to the center of the first circular ring to extrude the cable, and the two gears are meshed and matched to enable the two conveying wheels to simultaneously and reversely slide to convey the cable.
8. The automatic cable tensile strength tester according to claim 7, wherein the third driving unit includes a servo motor, the servo motor is slidably disposed on the first ring, the sliding direction of the servo motor is parallel to the sliding direction of the conveying wheels, and a power output end of the servo motor is coaxially and fixedly connected to any one of the conveying wheels.
9. The automatic cable tensile strength detector according to claim 1, wherein the movable clamping member further has a vertical downward moving pre-tightening stroke in front of the detection stroke, and in the pre-tightening stroke, at least one of the fixed clamping member and the movable clamping member pre-clamps the cable to straighten the section of the cable to be detected;
when the movable clamping piece moves to the junction of the pre-tightening stroke and the detection stroke, the fixed clamping piece and the movable clamping piece clamp the fixed cable.
