Abstract

The utility model relates to a tool knife for removing semiconductor layers from cable, which belongs to the technical field of manual tools for electricians. The utility model is used for solving the problems of difficulty in removing semiconductor layers and low efficiency while a cable end is fabricated. The utility model is composed of a handle and a knife head, and is characterized in that a clamping groove of the knife head is arranged at the front part of the handle, wherein the knife head is positioned in the clamping groove of the knife head through a sliding fit, the contour of the tip of the clamping groove of the knife head is matched with the contour of a knife edge and the front part of the handle is provided with a jack screw for fastening the knife head. The utility model relates to a tool knife exclusively for removing semiconductor layers from cable and wire, and the extended length of the knife edge can be adjusted according to need, especially micro adjustment. When semiconductor layers of cable are removed, the extended length of the knife edge can be adjusted to be smaller than the thickness of semiconductor layers and thus the main insulation can not be hurt in the operation process. When the tool knife is used, both the fabricating quality and work efficiency of the cable end can be raised.

Description

Cable stripping layer guarded blade utility knife

Technical field

The utility model relates to a kind of maintenance tool, and the dedicated tool especially for cable, electric wire stripping layer belongs to electrician's hand-operated tools technical field.

Background technology

Communication, machinery, electric equipment often will carry out the wiring operation of cable, electric wire when construction or maintenance circuit, the line end top layer will be peeled off a segment length during wiring.Be provided with the semiconductor layer of the balanced electric field of one deck as the main insulating layer outside of the twisted polyethylene cable that is used for high voltage power distribution in a large number, making cable end need divest certain-length when (comprising medial head and terminals) semiconductor layer, this layer thickness only has 0.5 millimeter, when operating, the electrician use common electrician's knife to divest usually, cutting semiconductor layer shallow is difficult for divesting, and operating efficiency is low; Cutting-in then might injure the main insulating layer of cable, make non-uniform electric, gently then cause cable end to shorten useful life; Heavy then cable end is blown out, influence safety, the stable operation of cable.Aforesaid operations, even have the workman of working experience for many years situation with the main insulating layer cut wound can take place often also, and after main insulating layer was by cut wound, remedial measure can only be with sand paper knife-edge part to be polished off, make the main insulating layer attenuation, its result directly has influence on insulation property.Chinese patent 98800498.4 disclosed a kind of armoured cable that is exclusively used in cable peeling peeling embedding, but because of complex structure, make difficulty, reason such as be not easy to carry and be difficult to promote the use of.

Summary of the invention

The utility model is used to overcome the defective of prior art and provides a kind of simple in structure, swift to operate and do not injure the cable stripping layer guarded blade utility knife of inner layer material.

The alleged problem of the utility model is that following technical scheme solves:

A kind of cable stripping layer guarded blade utility knife, comprise handle of a knife 4 and cutter head 5 in the formation, its special feature is: described handle of a knife front portion is provided with cutter head draw-in groove 7, described cutter head is positioned at this cutter head draw-in groove, between the two for being slidingly matched, cutter head draw-in groove end profile and blade 5-1 profile phase coupling, the handle of a knife front portion is provided with the fastening jackscrew 6 of cutter head.

Above-mentioned cable stripping layer guarded blade utility knife, described handle of a knife is provided with standby cutter head storage tank 3, and described standby cutter head storage tank is extended and forms along handle of a knife length by the cutter head draw-in groove.

Above-mentioned cable stripping layer guarded blade utility knife, described handle of a knife afterbody is provided with jackscrew spanner slot 1, and jackscrew spanner 2 is arranged in described slot.

The utility model divests the problem of semiconductor layer difficulty, poor efficiency when making cable end, has designed a kind of cable, the electric wire stripping layer guarded blade utility knife of being exclusively used in, and this guarded blade utility knife blade leans out length and can adjust as required, and particularly trace is adjusted.When being used to divest the semiconductor layer of cable, can with the adjustment of blade extension elongation be slightly smaller than semiconductor layer thickness, when operation, just can not injure main insulation like this.Use this guarded blade utility knife can make the making quality and the operating efficiency of cable end all be improved.In addition, the utility model profile is small and exquisite, compact conformation, be easy to carry, make easy, cheap, and has the general utility functions of universal cutter.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is Figure 1A-A cutaway view.

The label of each parts is expressed as follows in the accompanying drawing: 1. jackscrew spanner slot; 2. jackscrew spanner; 3. standby cutter head storage tank; 4. handle of a knife; 5. cutter head; 5-1. blade; 6. the fastening jackscrew of cutter head, 7. cutter head draw-in groove.

Embodiment

Referring to Fig. 1～Fig. 3, the utility model is made of handle of a knife 4 and cutter head 5, be provided with dovetail groove along the handle of a knife length direction, cutter head can be seated in the groove and can move in groove, between the two for being slidingly matched, the position that this groove is positioned at the handle of a knife front portion is a cutter head draw-in groove 7, and cutter head is fixed in the cutter head draw-in groove by the fastening jackscrew 6 of cutter head; This groove is standby cutter head storage tank 3 to the part that handle of a knife extends, and can be used for storing standby cutter head.The handle of a knife afterbody is provided with jackscrew spanner slot 1, and jackscrew spanner 2 is arranged in described slot.Cutter head draw-in groove end profile and blade edge profiles are complementary.

When the utility model is used for cable stripping layer, utilize the jackscrew spanner to unclamp the fastening jackscrew of cutter head, thickness according to shell layer is adjusted the blade extension elongation, usually the blade extension elongation is advisable for the thickness 2/3rds of stripping layer, then the fastening jackscrew of cutter head is screwed, the position of cutter head promptly is fixed, handle of a knife is answered the vertical-rise cable operation during cutting cable, because the position-limiting action of cutter head draw-in groove end, make depth of cut certain, can not injure the phenomenon of cable main insulation, stripping layer operation quality and efficient all can improve greatly.The jackscrew spanner not the time spent can be inserted in the jackscrew spanner slot, the cutter head storage tank can be stored several standby cutter heads.

The utility model also has the general utility functions of universal cutter, carries very convenient.
