Before connecting two cables to each other, the insulation of each cable must be stripped to a suitable length so that the conductors of the cables can be connected to each other. In order to achieve this purpose, various tools have appeared and have been introduced in the market. However, these conventional tools are difficult to peel off since they are operated by hand.

1 and 2, the cable peeler according to the present invention comprises: a hollow cylindrical cutter holder 1; Cutter 5; And shaft 7. The cutter holder 1 is entirely made of metal by casting, has a larger diameter first half 2 to accommodate cable 6 (see FIG. 5), and smaller to couple to an electric hand drill 8 It has a tail 3 in diameter. The protrusion 4 protrudes from the outer peripheral surface of the first half 2 of the cutter holder 1. A cutter mounting groove 41 is formed on the top of the protrusion 4 and extends into the first half of the cutter holder 1. The screw hole 42 penetrates the protrusion 4 and is formed in the cutter seating groove. The cutter 5 is seated in the cutter seating groove 41 and is firmly fixed to the screw hole 42 by the screw 9. When the cutter 5 is installed, a part of the cutter protrudes into the first half 2 of the cutter holder 1. The rear part 3 of the cutter holder 1 has a side threaded hole 31, so that a locating screw 32 for fixing the shaft 7 to the rear part 3 can be fixed to the side threaded hole 31. The shaft 7 has a front half 71 for connecting with the rear end 3 of the cutter holder 1; A trailing portion 74 (see FIG. 5) for engaging with the chuck of the electric hand drill 8; And a collar 72 between the first half 71 and the trailing end 74. Most of the plurality of concave holes 73 are formed in the outer circumferential surface of the first half 71 of the shaft 7 and are arranged at different distance intervals in the longitudinal direction from the collar 72. When the front end 71 of the shaft 7 is inserted into the rear end 3 of the cutter holder 1, the locating screw 32 is inserted into the side threaded hole 31 of the rear end 3 of the cutter holder 1 and into one of the concave holes 73 of the front end 71 of the shaft 7. By threading, the shaft 7 is firmly fixed to the cutter holder 1. The diameter of the collar 72 is larger than the inner diameter of the rear end 3 of the cutter holder 1, so that the collar 72 stops on the outside of the cutter holder 1 when the first half 71 of the shaft 7 is fully inserted into the rear end 3 of the cutter holder 1 . In addition, as the engagement point between the locating screw 32 and the first half 71 of the shaft 7 changes from one concave hole 73 to the other concave hole 73, the distance between the cutter 5 and the shear of the first half 71 of the shaft 7 changes relatively. do. Therefore, by adjusting the distance between the cutter 5 and the first half 71 of the shaft 7, the insulator 62 of the cable 6 can be cut to the desired length.

Referring to FIGS. 3 and 4 together with FIGS. 1 and 2, the cutter 5 is made entirely of special steel, the center of which is a screw hole 53 which is connected to the screw hole 42 of the protrusion 4 by the above-described screw 9. To have. The first half of the cutting surface of the cutter 5 is finished with two cutting blades, namely, the first cutting blades 51, 52 and the second cutting blade 54 in parallel. The first cutting edges 51, 52 have a gentle slope 51; And a major cutting edge 52 bent downward and protruding from the front end of the inclined portion 51. The gentle slope 51 points outwards. The major cutting edge 52 is connected inward and connected to the second cutting edge 54. As the cutter 5 rotates with respect to the cable 6, the gentle slope 51 moves along the outer surface of the insulator 62, and the major cutting edge 52 forces the insulator 62 to a predetermined depth. As the major cut edge 52 exerts a force towards the insulator 62, the gentle slope 51 blocks over the outer surface of the insulator 62, so that the cutting depth of the major cut edge 52 can be limited to a predetermined range. The second cutting edge 54 is longer than the first cutting edges 51 and 52 and has a substantially arcuate wheel angle. When the primary cutting edge 52 exerts force on the insulator 62, the second cutting edge 54 also exerts a force to cut the insulator to a constant depth as well as to remove the insulator 62 from the conductor 61.

Referring again to FIGS. 2 and 5, when the cable 6 is inserted into the cutter holder 1 and stopped at the first half 71 of the shaft 7, the rear end 74 of the shaft 7 is secured to the electric hand drill 8. Before operating the electric hand drill 8, the cable 6 must be held in place against the rotational movement or held firmly in the hand. When the electric hand drill 8 is actuated, the shaft 7 is driven to rotate the cutter holder 1 with respect to the cable 6 so that the cutting edges 51, 52, 53 of the cutter 5 push the insulator 62 of the cable 6 out of the conductor 61. During the peeling operation, the peeled insulator is thrown out of the cutter holder 1 through the cutter seating groove 43.
