Abstract

The utility model relates to a wire stripping knife. An upper clamp knife (3) is reversed 7-shaped; a lower clamp knife (11) is 7-shaped; the back portions of the upper clamp knife (3) and the lower clamp knife (11) are locked by a lock ring (2); the front portions of the upper clamp knife (3) and the lower clamp knife (11) are bended to form an upper inclined plane (5) and a lower inclined plane (10) which are opposite to each other; and the cutting edges formed by the upper inclined plane (5) and the lower inclined plane (10) are respectively provided with an M-shaped edge (6) and a W-shaped edge (9). Compared to the present stripping clamp, the double-strand wire stripping knife is advantageous in that the structure is simple, carrying is convenient, falling is prevented, etc.

Description

A kind of twinax cable bark knife

[technical field]

The utility model relates to a kind of electric wire bark knife, especially relates to a kind of twinax cable bark knife.

[background technology]

Known, in order to prevent that the position of electric wire beyond the non-interface from Lian Dianhuo occurring and wounding personnel, the electric wire outside will be provided with one deck electro-insulating rubber skin usually, the electro-insulating rubber skin of link need to be removed when using a bit of, in order to connect circuit; What use at present is wire stripping pliers, due to a lot of operating locations in the high-altitude, small space etc., wire stripping pliers are very heavy, and not only carry inconvenience, easily injure in case come off the staff that the bottom coordinates by a crashing object.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of twinax cable bark knife, the utility model has the advantages such as simple in structure, easy to carry, fall arrest with respect to existing wire stripper.

In order to realize described goal of the invention, the utility model adopts following technical scheme:

A kind of twinax cable bark knife, comprise upper clamp knife, lower clamp knife and lock ring, upper clamp knife, lower clamp knife are respectively " " " shape structure and reverse " " " shape structure, the rear portion of upper clamp knife and lower clamp knife locks by lock ring, is respectively equipped with " M " shape edge of a knife, " W " shape edge of a knife on the cutting edge that ramp relative after the anterior bending of upper clamp knife and lower clamp knife, lower inclined plane form.

Described twinax cable bark knife is provided with downward lengthening blade at the middle part of " M " of upper clamp knife bending end shape edge of a knife.

Described twinax cable bark knife is provided with at the middle part of " W " of lower clamp knife bending end shape edge of a knife and upwards lengthens blade.

Described twinax cable bark knife is outside the corresponding lower clamp knife bending of the upper clamp knife bending end inner face of described upper clamp knife and lower clamp knife end; Wherein the ramp of upper clamp knife inboard is blade, is blade outside the lower inclined plane of lower clamp knife.

Described twinax cable bark knife, described lock ring are columnar structured, and the two ends up and down of columnar structured lock ring are stuck on the top and bottom, rear portion of upper clamp knife and lower clamp knife by flanging respectively, are provided with the perforation of perforation on lock ring.

Described twinax cable bark knife is provided with non slip surface on the upper side of upper clamp knife.

Described twinax cable bark knife is provided with non slip surface on the bottom surfaces of lower clamp knife.

Owing to having adopted technique scheme, the utlity model has following beneficial effect:

Twinax cable bark knife described in the utility model, utilized the principle of nail clipper, by with upper clamp knife bending end ring shifting to install around lower clamp knife bending end, the twinax cable that makes utilizes the utility model peeling fast when peeling, comparatively practical and convenient, the utility model is not only easy to carry, and cost is very low, is beneficial to power department and promotes the use of.

[description of drawings]

Fig. 1 is perspective view of the present utility model.

Fig. 2 is the counter structure schematic diagram outside upper clamp knife bending end inner face of the present utility model and lower clamp knife bending end.

In figure: 1, perforation; 2, lock ring; 3, upper clamp knife; 4, non slip surface; 5, ramp; 6, " M " shape edge of a knife; 7, lengthen blade downwards; 8, upwards lengthen blade; 9, " W " shape edge of a knife; 10, lower inclined plane; 11, lower clamp knife; 12, upper clamp knife bending end; 13, lower clamp knife bending end.

[embodiment]

By the following examples can be detailed explanation the utility model, open the purpose of this utility model is intended to protect all technological improvements in the utility model scope,

1 or 2 described twinax cable bark knives by reference to the accompanying drawings, comprise upper clamp knife 3, lower clamp knife 11 and lock ring 2, upper clamp knife 3, lower clamp knife 11 is respectively " " " shape structure and reverse " " " shape structure, be provided with non slip surface 4 on the upper side of upper clamp knife 3, be provided with non slip surface 4 on the bottom surfaces of lower clamp knife 11, the rear portion of upper clamp knife 3 and lower clamp knife 11 is by lock ring 2 lockings, described lock ring 2 is columnar structured, the two ends up and down of columnar structured lock ring 2 are stuck on the top and bottom, rear portion of upper clamp knife 3 and lower clamp knife 11 by flanging respectively, be provided with the perforation 1 of perforation on lock ring 2, relative ramp 5 after the anterior bending of upper clamp knife 3 and lower clamp knife 11, be respectively equipped with " M " shape edge of a knife 6 on the cutting edge that lower inclined plane 10 forms, " W " shape edge of a knife 9, the middle part of " M " shape edge of a knife 6 of wherein said upper clamp knife bending end 12 is provided with downward lengthening blade 7, the middle part of " W " shape edge of a knife 9 of described lower clamp knife bending end 13 is provided with and upwards lengthens blade 8, the corresponding lower clamp knife bending end of upper clamp knife bending end 12 inner faces 13 outsides of described upper clamp knife 3 and lower clamp knife 11, wherein ramp 5 inboards of upper clamp knife 3 are blade, and lower inclined plane 10 outsides of lower clamp knife 11 are blade.

implement twinax cable bark knife described in the utility model, when using the utility model, twinax cable is inserted between " M " shape edge of a knife 6 and " W " shape edge of a knife 9, thumb firmly presses down the non slip surface 4 of upper clamp knife 3, upper clamp knife bending end 12 described " M " the shape edge of a knife 6 of upper clamp knife 3 just separates the inside and outside two-layer skin of twinax cable with lower clamp knife bending end 13 described " W " the shape edge of a knife 9 of lower clamp knife 11, just can utilize downward lengthening blade 7 after two-layer skin inside and outside taking off and upwards lengthen blade 8 operations the crust of twinax cable is a bit of in cutting, then utilizing blade on " M " shape edge of a knife 6 and " W " shape edge of a knife 9 outside lower inclined planes 10 and ramp 5 that crust is divided slices off, but then just wiring work, the utility model is simple in structure, rope can be through during operation in the perforation 1 of lock ring 2 and be suspended on loins.

The utility model does not describe part in detail and is prior art.
