Abstract
The invention relates to a power construction portable tool, in particular to a portable gun-like electrician's knife, and solves the problem that an existing cable sheath peeling tool easily causes damage to optical fiber, is unsafe to operate and is low in efficiency.A technical scheme includes: the portable gun-like electrician's knife comprises a gun-like frame composed of a grooved gun body and a handle; a tool holder is hinged in the gun body, a bent portion of the tool holder is hinged to the gun body, a blade is fixed to an end of the tool holder, and the other end of the tool holder and the handle form an included angle; a grooved portion of the gun body in hinging connection with the tool holder is internally provided with a limiting groove in which a limiting screw is fastened; an end of the tool holder is hinged to a fastener.The portable gun-like electrician's knife has the advantages that the structural design is ingenious, cutting depth is controllable, and the optical fiber inside is never damaged; work efficiency is improved greatly, and a cable sheath can be cut vertically and circumferentially; the knife is simple and quick to operate and is safe and free of injuring an operator.
Description
Technical field
The present invention relates to power construction portable instrument, be specially Portable gun type electrician's knife.
Background technology
In power construction, it is often necessary to the operation that the crust of optical cable is peeled off, owing to lacking special cable sheath exfoliation tool at present, in practical operation, workman can only use common paper knife to carry out cable sheath exfoliation operation.Due to the degree of depth of incision uncontrollable when paper knife uses, often easily damage cable interior optical fiber, and when scribing cable sheath easy sideslip, accidentally injure workman's finger, the back of the hand.Therefore, designing a kind of safety operation, portable optical fiber cable skin peels off dedicated tool and is extremely necessary.
Summary of the invention
This invention address that existing cable sheath exfoliation tool is easily damaged optical fiber, operated problem dangerous, inefficiency, it is provided that a kind of Portable gun type electrician's knife.
The present invention is achieved by the following technical solutions: Portable gun type electrician's knife, and including gun-shaped support body, described support body is made up of the flute profile body of a gun that Open Side Down and the gripping handle being fixed on body of a gun right-hand member；L-shaped knife rest it is hinged with in the described body of a gun, the kink of described knife rest is hinged with the body of a gun, one end of described knife rest in the flute profile of the body of a gun with body of a gun keeping parallelism leave gap, this termination of described knife rest is fixed with the blade that cutting edge is downward, and the other end of described knife rest forms angle with gripping handle；Above the described body of a gun and knife rest articulated section, have stopper slot in the flute profile of the body of a gun, be screwed with one end in described stopper slot and stretch out the stop screw of body of a gun flute profile；The body of a gun termination in described knife rest front is connected to the semicircle buckle that Open Side Down, and the top of described buckle is hinged with body of a gun termination.Hinged knife rest in the flute profile body of a gun, pulls the angle portion between knife rest and gripping handle, and the blade of knife rest termination can cut downwards.Stopper slot in the flute profile of the body of a gun can ensure that during blade holder turns, rear portion is unobstructed, the stop screw adjustable knife rest anglec of rotation, and then controls the blade depth of cut of knife rest termination.Body of a gun termination is hinged with semicircle buckle, may be stuck in outside optical cable, plays the effect of fixing electrician's knife position, when needing longitudinally cutting cable sheath, semicircle buckle keeps vertical with gun-shaped support body, and blocks cable sheath, when needing annular cutting cable sheath, after buckle is reversed 90 °, block cable sheath.
Described blade is wallpaper cutter blade.Cutting cable sheath mainly uses the point of a knife part of blade, uses wallpaper cutter blade can break breaking nose part after corner wear section by section, makes full use of each joint point of a knife cutting crust.It is connected to back-moving spring between the described knife rest other end and gripping handle.Back-moving spring can reset by cutter setting frame.
The invention have the advantages that 1, smart structural design, depth of cut can be controlled, it is ensured that internal optical fiber will not be damaged；2, work efficiency is greatly promoted, and quickly longitudinal, annular can cut cable sheath；3, simple and quick, and safety, operator will not be accidentally injured.
Accompanying drawing explanation
Fig. 1 is longitudinal sectional view of the present invention；
Fig. 2 is buckle structure schematic diagram；
In figure: the 1-body of a gun, 2-gripping handle, 3-knife rest, 4-blade, 5-back-moving spring, 6-stop screw, 7-buckle.
Detailed description of the invention
Portable gun type electrician's knife, including gun-shaped support body, described support body is made up of the flute profile body of a gun 1 that Open Side Down and the gripping handle 2 being fixed on the body of a gun 1 right-hand member；It is hinged with L-shaped knife rest 3 in the described body of a gun 1, the kink of described knife rest 3 is hinged with the body of a gun 1, one end of described knife rest 3 in the flute profile of the body of a gun 1 with the body of a gun 1 keeping parallelism leave gap, this termination of described knife rest 3 is fixed with the downward blade of cutting edge 4, and the other end of described knife rest 3 and gripping handle 2 form angle；Above the described body of a gun 1 and knife rest 3 articulated section, have stopper slot in the flute profile of the body of a gun 1, be screwed with one end in described stopper slot and stretch out the stop screw 6 of the body of a gun 1 flute profile；The body of a gun 1 termination in described knife rest 3 front is connected to the semicircle buckle 7 that Open Side Down, and the top of described buckle 7 is hinged with the body of a gun 1 termination.
When being embodied as, described blade 4 is wallpaper cutter blade.It is connected to back-moving spring 5 between described knife rest 3 other end and gripping handle 2.
During use, optical cable according to different-diameter and skin thickness, regulate stop screw 6, controlling the depth of cut of blade 4 point of a knife, be then first adjusted to by buckle 7 and the body of a gun 1 vertical direction, buckle 7 is stuck on cable sheath, pull the angle portion of knife rest 3 and gripping handle 2, then holding with a firm grip gripping handle 2, axially pull the present invention along optical cable, blade 4 can cut out an axial slot on cable sheath.Then by buckle 7 half-twist, then blocking cable sheath, pull the angle portion of knife rest 3 and gripping handle 2, gripping handle 2 of holding with a firm grip, along optical cable ring rotation one week, blade 4 can cut out annular slot on cable sheath.Cable sheath can be peeled off and not damage internal optical fiber by such two slots smoothly.
