Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a tool for quickly testing cables. Background Art

[0002] Non-destructive testing of cables refers to tests performed without damaging the wires and cables, such as conductivity, contact resistance, insulation resistance, etc. Destructive testing refers to tests performed while damaging the wires and cables, such as tensile strength, voltage resistance, combustion performance, etc. Non-destructive testing generally uses electronic instruments to measure wires and cables, such as ohmmeters, voltmeters, ammeters, oscilloscopes, etc. Destructive testing generally uses physical instruments to operate on wires and cables, such as universal tensile testing machines, high-voltage generators, combustion boxes, aging boxes, etc.

[0003] For example, in a cable testing tool with the authorization announcement number "CN210774102U", the user manually places the cables in the slots of the cable fixing group, and manually turns the second screw, so that the second screw drives the fourth screw to rotate under the action of the hinged rod, so that the second fixing seat moves upward, which is convenient for the user to fix the cable. However, the cable fixing seat is used to fix the cable for testing. Since the position and shape of the cable fixing seat are fixed, it is not suitable for fixing cables of different sizes, which has high limitations. At the same time, the staff shakes the handle to drive the thread to rotate so that the slider slides to tighten the cable. When the cable is too long, the staff needs to shake the handle multiple times to reach the position, which makes the cable testing work slow. Utility Model Content

[0026] Cable quick test fix and deploy work:

[0027] When the cable needs to be tested, the two ends of the cable are respectively placed in the grooves processed on the surfaces of the multiple clamping plates 201, and then the two bolts 9 are rotated upward.
