Abstract

The utility model relates to an adjustable hand cable stripper which is suitable for serving as a hand tool for stripping outer covers of cables, etc. A cross beam is fixedly connected with a guide rod which forms a sliding fit with a guide frame, and an n-shaped frame is formed. The cross beam forms a sliding fit with an eccentric cutting tool assembly. The guide frame is fixedly connected with a guide wheel shaft which forms a sliding fit with a guide wheel. The cutting tool assembly comprises a slide barrel which forms a sliding fit with the cross beam. A bulge is arranged in the slide barrel for limiting the rotation of a sleeve barrel which forms a sliding fit with the slide barrel. Springs are arranged in the slide barrel and on the upper end of the sleeve barrel. The sleeve barrel forms screw connection with a hollow screw which forms a sliding fit with a bearing liner. An eccentric cutter forms a sliding fit with the bearing liner. The cross beam is provided with a sloping handle. The utility model has the advantages of convenient operation, high safety and high work efficiency.

Description

The manual adjustable cable-stripper

The utility model relates to a kind of manual adjustable cable-stripper, is applicable to the hand-operated tools of making cylindrical object crusts such as strip cable.

At present, the strip cable crust is many to carry out with electrician's knife, has following problem: firmly determined by staff because of the degree of depth of incision cable sheath, be difficult for grasping, easily the cut wound cable core; When the thickness of quilt stripping cable skin was big, electrician's knife was difficult for cutting stripping, and easily hurts operator's hand; In the time of need peeling off the cable skin of longer size, effort, time-consuming; Cut when shelling the cable skin of fixing on the wall,, operate very inconvenient because of cannot see by wall any face; Existing stripping cable instrument only is applicable to the cable that diameter is less, can't satisfy the needs of real work.

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, a kind of manual adjustable cable-stripper safe, quick, easy to carry is provided, thereby increases work efficiency.

Realize that the technical measures that the utility model is taked are that this cable-stripper is constructed as follows: crossbeam and guide rod are connected, guide rod and saddle are sliding fit formation " Contraband " shape framework, and the crossbeam other end is equipped with eccentric toolbox; The slide cartridge of vertical square hole and assembly is sliding fit on the crossbeam, slide cartridge endoporus and sleeve are sliding fit, the slide cartridge endoporus is provided with spacing preiection, prevent the sleeve rotation, the step of slide cartridge upper end prevents that eccentric toolbox from coming off, be provided with spring to regulate the cutting force of cutter in slide cartridge and between the sleeve upper end, the outer one side of slide cartridge is provided with sour jujube bar tooth, be abutted against with ratchet hinged on the crossbeam, make toolbox can stop at the height and position of arbitrary needs, in the plane vertical, be provided with the inclination handle with " Contraband " shape framework, being convenient to can be convenient when vertically cutting cable, operation cosily, guide wheel shaft and guide wheel that the saddle opposite side is connected are sliding fit, place in the V-shaped groove that two guide wheels constitute by the stripping cable to reduce friction.

The utility model has the advantages that: regulate hollow screw, can more accurately locate the degree of depth of cutter head incision cable, because sleeve and spring in the adjustable eccentric toolbox can adapt to the needs of cutting the various complicated shape cable sheaths of stripping; Easy to operate, particularly in that to cut stripping convenient especially when being fixed on the cable of the less occasion in the first-class operating space of wall.

Fig. 1 is an example structure partial cutaway of a utility model front view, Fig. 2 is that partial sectional view is looked on the right side of Fig. 1, Fig. 3 is the vertical view of Fig. 1, Fig. 4 is the A-A partial sectional view of Fig. 1, Fig. 5 is the stereogram of the utility model operating state, Fig. 6 be eccentric cutter cut the stripping one section cable skin walk the route schematic diagram.

Below in conjunction with accompanying drawing structure of the present utility model and embodiment are described further; this cable-stripper is constructed as follows: see Fig. 1; Fig. 2; crossbeam 1 is through the pin 2 that rises; hollow pins 3 is connected with square guide rod 4; guide rod 4 is sliding fit with the square hole of saddle 5; the guide rod cross section; the corresponding hole of crossbeam and saddle also can be triangle; selling 19 is abutted against with hinged ratchet 6 one ends of saddle 5 and the sour jujube bar tooth of guide rod; the other end is abutted against through spring 18 and saddle; lower end of the guide rod is provided with step B; to prevent that saddle from coming off from guide rod; crossbeam; guide rod; saddle connects and composes " Contraband " shape framework; see Fig. 4; the slide cartridge 9 that the crossbeam other end is provided with vertical square hole and eccentric toolbox is sliding fit; slide cartridge endoporus and sleeve 24 are sliding fit; the slide cartridge inner headed face is provided with protruding E; circumferentially be sliding fit with the vertical slot edge on the sleeve periphery; with the rotation of restriction sleeve; the slide cartridge upper end is provided with step C; to prevent that eccentric toolbox from coming off from crossbeam; top in slide cartridge; the upper end of sleeve is provided with spring 23; its effect is to adjust the active force of cutter to workpiece; its cushioning effect can protect cutter not to be destroyed; see Fig. 3; the outer one side of slide cartridge is provided with sour jujube bar tooth; with sell 21 hinged ratchet 16 1 ends on the crossbeam 1 and be abutted against; the stage clip 20 that is provided with in the ratchet other end and crossbeam 1 groove is abutted against; sleeve 24 endoporus and hollow screw 25 are threaded; hollow screw endoporus and bearing shell 27 are sliding fit; bearing shell and eccentric cutter 10 are sliding fit; cutter 10 is abutted against in the upper surface of bearing shell 27 through open card bad 26, makes point of a knife according to being subjected to the difference of force direction can carry out 360 ° of rotations.See Fig. 2, Fig. 3, in crossbeam other end square hole center line and the plane vertical, be provided with inclination handle 7 with " Contraband " shape framework, handle inserts in the groove of crossbeam 1 boss, through little axle 22, fixedly cap 17 is connected, little axle is sliding fit with locking cap, hole on locking cap and the crossbeam boss is tight fit, nut 8 is threaded with the handle step, inclined-plane on the end face of nut step and the crossbeam boss is abutted against, handle is provided with ramp projections D above the middle part, during operation, mother is referred to can make things convenient for, cosily spur cable-stripper by on the inclined-plane of protruding D.Saddle 5 opposite sides are connected with guide wheel shaft 13 through the pin 14 that rises, hollow pins 15, and guide wheel 12 is sliding fit with guide wheel shaft 13.
