Description

A kind of rubber-insulated wire steel wire is driven a point instrument

Technical field

The utility model relates to the constructing technology field of cutting apart with instrument, refers to that especially a kind of rubber-insulated wire steel wire drives a point instrument.

Background technology

Covered wire cable mostly is single core, twin-core structure, also can make quadrature arrangement, and xsect is 8 fonts, and reinforcement is positioned at Liang Yuan center, can adopt metal or nonmetal structure, and optical fiber is positioned at the geometric center of 8 fonts.While out of doors covered wire cable being installed, in default of driving accordingly a point instrument, be often the strip of paper used for sealing that is torn by hand parcel reinforcement.The rupture surface that hand tears is uneven, and volume is not of uniform size.In the time being fit into connector, Chang Yinwei size unbalanced and cannot be applicable to heat-shrink tube, needs to open in addition point one section of covered wire cable thus.Can cause like this waste of covered wire cable.The problems referred to above are needed technological improvement badly and are solved.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, volume is little, easy to carry, and the effective rubber-insulated wire steel wire of covered wire cable steel wire stripping is driven to a point instrument.

For realizing the purpose of this utility model, intend by the following technical solutions:

A kind of rubber-insulated wire steel wire is driven a point instrument, it is characterized in that: comprise pedestal, open a point blade, the described point blade of opening is arranged on pedestal; Described pedestal comprises press handle and base, and the afterbody of press handle and base is connected, and between press handle and base, has spring.

Further, there is pickup groove at the described press handle position corresponding with base head, and pickup groove is vertical with base with press handle; On pickup groove, be equipped with vertical masonry joint, the described point blade of opening is arranged on position corresponding in seam, and point of a knife is given prominence to vertical masonry joint.When use, covered wire cable is put into pickup groove, press handle is pressed toward base direction, open point strip of paper used for sealing at blade pierces covered wire cable steel wire reinforcement place, firmly this instrument is firmly pulled along covered wire cable, or covered wire cable is pulled out again, can reach the effect that rubber-insulated wire steel wire is opened point.

Further, the end points of described vertical masonry joint is positioned on the perpendicular bisector of pickup groove broadside.Opening a point blade is arranged in vertical masonry joint, just because of the end points of vertical masonry joint is on the perpendicular bisector of press handle and base head broadside, thereby it is smooth to guarantee to open point two core edges of rear covered wire cable, and size equalization, can reduce like this because not of uniform size and cannot be applicable to unified heat-shrink tube, cause the situation of covered wire cable waste.

Further, top side and the outside of described press handle head are provided with screw, and the bottom side of base head and outside are also provided with screw, in described screw, are provided with dog screw.After opening a point blade and packing in vertical masonry joint, dog screw is packed in screw, prop up out a point blade, prevent blade because loosening after repeatedly using.

Further, described press handle is connected by pin with base afterbody.The setting of pin, can guarantee that the afterbody of press handle and base can move relative to doing circular arc, and the setting of spring can allow press handle and base after opening, can independently be returned to certain position, can person's one-handed performance easy to use.

When the utility model uses, now covered wire cable is put into pickup groove, press handle is pressed toward base direction, point blade of holding being arranged on press handle and base can block the strip of paper used for sealing that steel wire reinforcement goes out and be punctured, user pulls covered wire cable and this instrument during toward contrary direction, the core of covered wire cable can be divided into impartial two parts by neat, can increase the heat-shrink tube that is used in a class specification after covered wire cable is opened point, has reduced the waste of covered wire cable.In addition, the screw on press handle and base and dog screw, can complete out the fixing of point blade.

Fig. 1 is the utility model example structure schematic diagram.

Fig. 2 is that the utility model embodiment uses view.

Embodiment

Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.

In conjunction with Fig. 1 and Fig. 2, the utility model relates to a kind of rubber-insulated wire steel wire and drives a point instrument, comprises pedestal 1, opens point blade 2, and pedestal 1 comprises press handle 11 and base 12, the afterbody of press handle 11 and base 12 is connected by pin 18, between press handle 11 and base 12, has spring 13.Press handle 11 has pickup groove 14 with the corresponding position of base 12 heads, and pickup groove 14 is vertical with base 12 with press handle 11; On two pickup grooves 14, be equipped with vertical masonry joint 15, the end points of vertical masonry joint 15 is on the perpendicular bisector of pickup groove 14 broadsides, and the length of vertical masonry joint 15 is less than the length of pickup groove 14, highly equals the height of press handle 11 and base 12 heads; Open point blade 2 and be arranged on position corresponding in vertical masonry joint 15, point of a knife is given prominence to vertical masonry joint 15; Top side and the outside of press handle 11 heads are provided with screw 16, and bottom side and the outside of base 12 heads are also provided with screw 16, in above-mentioned screw 16, are provided with dog screw 17.The setting of spring 13, can allow press handle 11 and base 12 can independently be returned to certain position after opening, energy person's one-handed performance easy to use, and the setting of pin 18, can guarantee that the afterbody of press handle 11 and base 12 can move relative to doing circular arc.On the perpendicular bisector of the end points place pickup groove 14 of vertical masonry joint 15, thereby after guaranteeing to open point, two core edges of covered wire cable are smooth, and size equalization, can reduce like this because of not of uniform size and cannot be applicable to unify heat-shrink tube, cause the situation of covered wire cable waste.

When use, covered wire cable is put into pickup groove 14, press handle 11 is pressed toward base 12 directions, open the strip of paper used for sealing that point blade 2 punctures covered wire cable steel wire reinforcement place, firmly this instrument is firmly pulled along covered wire cable again, or covered wire cable is pulled out, can reach the effect that rubber-insulated wire steel wire is opened point.The utility model is simple in structure, but can solve preferably the existing defect of prior art, is worthy to be popularized.
