Abstract

The utility model relates to a round tray type plastic cable stripping knife. The knife is provided with a movable tray 8 which can rotate and is sheathed on the outer wall of the inner circle of a fixed tray 2, and a claw 5, a longitudinal cutting rod sheath 13 and a ring cutting rod sheath 14 which form an included angle of 120 DEG on the circumference and are connected with the movable tray into a whole by a sliding screw 9 and a locking thread tie are arranged on the fixed tray. A knife head 3 and a knife rod 1 are inserted together by heterotype interfaces, and a nut 6 for adjusting the advancement of the knife adjusts the depth of the advancement of the knife to cut the outer sheath of a cable around the cable or cut the outer sheath of a cable in the longitudinal direction, so the utility model flakes off the rubber outer sheath of a cable head when the utility model is used for installing the rubber cables of various specifications.

Description

Plastic cable stripping knife

The present invention relates to the cutter that a kind of rubber and plastic overcoat cable peeling is used, is that a kind of rubber plastic cable that can apply to all size isolates the bark knife of peeling cable head rubber and plastic overcoat off when wiring is installed.

At present, be widely used in the cutter that the peeling of various rubber and plastics cover cable end is used, be hook hilted broadsword that installation personnel grinds with stalloy or general electrician's knife, use extremely effort, labour intensity is big, is difficult for when exerting oneself grasping, work efficiency is low, and scratches finger easily and cause personal injury.

The object of the present invention is to provide a kind of simple in structure, easy to operate, safe and reliable, the disc type rubber plastic cable bark knife that efficient is high.

The present invention is achieved in that the rubber plastic cable bark knife is made up of the screw of fixed disk, claw, knife bar, vertical circular cutter and various different purposes.Movable disk is contained on the fixed disk, can left-right rotation, and claw and knife bar cover are in screw in the movable disk slideway of rotation and drive and be synchronized with the movement.When being stuck in the outer round surface of cable, system is fixed on movable disk on the fixed disk with locking screw, adjusts the depth of cut of circular cutter or longitudinal knife again, rotates or be pulled outwardly the moving knife tool, and the rubber plastic cable cover is cut off and peels off.

The concrete structure of invention is provided by following examples and accompanying drawing.Fig. 1 is the structural representation of the disc type rubber plastic cable bark knife of proposition according to the present invention.Describe the details and the operating position of the concrete device that proposes according to the present invention in detail below in conjunction with Fig. 1.

As can be seen from Figure 1, the movable disk 8 of rubber plastic cable bark knife is set on the fixed disk 2, the two by locking screw be 10 and sliding screw 9 be connected as a single entity.Claw 5, rip cutting knife bar cover 13, ring cutting knife bar cover 14 place respectively on the inside and outside circle of fixed disk 12, in the through hole insertion fixed disk by inside and outside circle, and are under the constraint of sliding screw 9.Because the conduit of three same trajectories is arranged on the movable disk 8, when rotating movable disk 8, make the swing offset of movable disk 8 become the advance and retreat displacement of claw 5, rip cutting knife bar cover 13, ring cutting knife bar cover 14.The inner peak of claw 5, vertical cutter knife bar cover 13, ring cutting knife bar cover 14 always is on three Along ents of same circumference, and forms 120 ° of angles, its central axis is the center of circle by fixed disk 2 all.Knife bar 1, cutter head 3 are connected as a single entity by a special-shaped groove, are arranged in the centre bore and cutter head groove of knife bar collet 13,14, adjust advance and retreat cutter nut 6, can make cutter head 3 inside and outside moving.Knife bar 1 outer end head is provided with the size that scale demonstrates the advance and retreat cutter.Sliding screw cover 7, pin hold-down screw cover 12 is enclosed within respectively and plays the fixing effect on the screw rod.The steel ball 4 main resistances that reduce in cutter rotation and the drawing process that rise.

During use, turn the advance and retreat cutter and adjust nut 6, make vertical circular cutter all fall back on knife bar cover 13, in 14, rotate movable disk 8 and make claw 5, rip cutting knife bar cover 13, ring cutting knife bar cover 14 outer moving, be enclosed within then on the position that cable need cut, left-handed movable disk 8, make claw 5, rip cutting knife bar cover 13, cable sheath is close on the top of ring cutting knife bar cover 14, and tightening the movable disk locking screw is 10, allows movable disk 8 tightly be fixed on the fixed disk 2, adjust the circular cutter insertion depth according to the thickness of rubber plastic cable sheath, rotate a week along the cable cylindrical, observe and whether cut, recall to circular cutter, in circular cutter knife bar cover 14, ring cutting is finished.Turn longitudinal knife advance and retreat cutter adjustment nut 6 and to desired depth, reposefully the central axis of cutter para-electric cable is pulled out, peel cable cover(ing) along otch and get final product.

Description of drawings: 1 knife bar, 2 fixed disks, 3 cutter heads, 4 steel balls, 5 claws, 6 advance and retreat cutter adjusting nuts, 7 sliding screw covers, 8 movable disk, 9 sliding screws, 10 locking screws system, 11 slideways, 12 locking screw covers, 13 rip cutting knife bar covers, 14 ring cutting knife bar covers.
