Description

A cable peeling device and method of using the same

technical field

The invention belongs to the technical field of cables, and in particular relates to a cable peeling device, and also relates to a method for using the device.

Background technique

A cable is a wire that transmits electricity or information from one place to another, made of one or more conductors insulated from each other and an outer insulating protective layer. When wiring the cable or making the cable head, the outer insulation layer needs to be removed.

At present, the existing peeling method is to use a wallpaper knife to peel off the cable skin, but the direction of the wallpaper knife is not easy to fix during the sliding cutting process, and it is easy to slip off and scratch the hand. At the same time, when peeling the unarmored cable with a wallpaper knife, it is a test of the operator's skill. Too much force will easily damage the cable core, and too little force will not be able to peel off the cable sheath at one time.

Therefore, in view of the problem that the existing manual wallpaper knife cannot effectively peel the cable and is unsafe, it is an urgent problem to develop a cable peeling device that can effectively peel the cable.

SUMMARY OF THE INVENTION

In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a cable peeling device, so as to solve the problem that the cable cannot be effectively peeled by manual use of a wallpaper knife and is unsafe.

The technical solution adopted by the present invention to solve the above technical problems is: a cable peeling device, comprising a snap ring, a tool holder, a tool handle and a blade, the tool holder is mounted on the snap ring, and the tool handle is rotatable Installed on the knife holder, the blade is detachably installed on the knife handle, the snap ring is provided with a cutting opening and a cutting groove at a position close to the knife handle, and the knife handle can be between the cutting opening and the cutting groove After the rotation is performed and the cutting direction of the blade changes after the rotation, a positioning mechanism is installed on the snap ring. When the snap ring is sleeved on the cable, it is positioned by the positioning mechanism; the inclination angle of the blade is controlled by the rotation of the knife handle on the knife holder, so as to realize the height adjustment of the blade, so that the cutting depth of the blade can be controlled to adapt to different types of cables; by setting The cutting edge and the cutting groove, the knife handle rotates between the two, first, place the knife handle in the cutting port, at this time, the cutting edge of the blade faces the axial direction of the cable, and slides along the axial direction of the cable to scratch the cable skin An axial incision is made, and then the handle is turned to place the handle in the cutting groove. At this time, the cutting edge of the blade faces the radial direction of the cable, rotates around the cable, and cuts off the cable sheath. Reversing the direction, you can easily realize the cable peeling operation. In addition, the traditional manual hand-held wallpaper knife peeling and easily scratching hands and other unsafe phenomena are avoided, and the safety is improved.

Further, the tool rest includes a connecting column and a rotating bracket, the connecting column is fixedly installed on the snap ring, the rotating bracket is rotatably mounted on the connecting column, and the rotating bracket is located outside the snap ring.
