In this embodiment, the metal baffle is located on one side of the rear baffle.

The large hole at the front end of the tooling shell is used to cover the fingers when the radio frequency cable is turned and cut during the process of stripping the radio frequency cable. A key chain can be added to the back for easy portability.

The concrete using method operation steps of this embodiment are as follows:

Step 1, according to the requirements of use, rotate the second screw to adjust the depth of the circular cutting and longitudinal cutting;

Step 2, in order to ensure accurate wire cutting, it is necessary to ensure that the cross section of the cable is perpendicular to the cable axis and is flat. Therefore, first insert the cables into the B, C, and D ring cutting holes in sequence, all against the metal baffle, to ensure that the three hole ring cutting processes are all carried out on the same plane. Medium, D hole cuts off the inner core, at this time, the cable section is perpendicular to the cable axis and flat.

Step 3, according to the requirements of use, adjust the distance between the metal baffle and the shell to ensure the length of stripping; rotate the second screw again to adjust the depth of the ring cutting and slitting;

Step 4, put the RF cable into the B hole of the ring tangent hole, the front end of the cable is against the inside of the metal baffle, and press the pressing plate with your fingers, so that the strong magnet can attract the second screw connected to the pressing plate;

Step 5, cover the finger hole with the index finger, and rotate the tooling for one week;

Step 6, move the pressing plate with the thumb to separate the bottom end of the second screw from the strong magnet, the first cutter leaves the cable sheath, and then pull out the RF cable; complete the loop cutting of the cable sheath;

Step 7: Insert the RF cable into the hole of the longitudinal tangent line A, press the pressing plate with your fingers, and use the second cutter to cut longitudinally; pull out the RF cable to complete the longitudinal cutting of the cable sheath;

Step 8, peel off the cut RF cable sheath by hand;

Step 9, the shielding net of the RF cable is spread out by hand to expose the cable dielectric layer;

Step 10, insert the cable with the exposed cable medium layer into the hole C of the ring tangent line, repeat steps 4 to 6, after the ring cutting is completed, remove the medium layer with needle-nose pliers; finally complete the wire stripping.

In the process of stripping, because the length of the outer sheath of the RF cable needs to be cut longer than required and the length of the dielectric layer of the RF cable, when the dielectric layer is cut, the dielectric layer of the RF cable extends into the C hole, and the diameter of the C hole is smaller than the outer sheath. Therefore, the outer sheath of the radio frequency cable is against one side of the outer casing, and there is a certain distance between this side of the outer casing and the first cutter. The distance can be limited by the thickness of the outer casing. In this embodiment, the distance is 3mm ; In this way, the outer sheath of the radio frequency cable and the dielectric layer of the radio frequency cable of different lengths are cut out.

After the stripping tool is completed, clean the blade with a cloth, press the button to make the strong magnet attract it, and restore the metal baffle to the original storage position, which is convenient for storage and carrying.

Brief working principle of the present invention:

1. A tool for stripping RF cables is to strip the RF cables through cutters in different holes on the tooling. The first cutter in hole B can cut the outer dielectric skin of the RF cable in a circular manner. , the second cutter in hole A can cut the outer dielectric sheath of the RF cable longitudinally, and then the cable sheath can be easily removed. The C hole is to circumscribe the metal inner core dielectric insulation layer of the RF cable, and then the stripped metal inner core dielectric insulation layer can be easily removed.
