Description

Portable gun-shaped electrician's knife

technical field

The invention relates to a portable tool for electric power construction, in particular to a portable gun-shaped electrician's knife.

Background technique

In electric power construction, it is often necessary to peel off the sheath of the optical cable. Due to the lack of special tools for peeling the sheath of the optical cable, workers can only use a common paper cutter to peel the sheath of the optical cable in actual operation. Since the cutting depth cannot be controlled when the paper cutter is used, it is often easy to damage the optical fiber inside the optical cable, and it is easy to deviate when cutting the outer skin of the optical cable, accidentally injuring the fingers and back of the hand of the worker. Therefore, it is very necessary to design a kind of safe operation, portable optical cable sheath peeling special tool.

Contents of the invention

The invention solves the problems that the existing optical cable peeling tool is easy to damage the optical fiber, unsafe to operate and low in efficiency, and provides a portable gun-shaped electrician's knife.

The present invention is achieved through the following technical proposals: the portable gun-shaped electrician's knife includes a gun-shaped frame body, the frame body is composed of a groove-shaped gun body with an opening downward and a grip handle fixed at the right end of the gun body; The body is hinged with an L-shaped knife rest, and the bending part of the knife rest is hinged with the gun body. One end of the knife rest is kept parallel with the gun body in the groove shape of the gun body and leaves a gap. The end is fixed with a blade with a downward edge, and the other end of the knife rest forms an angle with the grip handle; above the hinged part of the gun body and the knife rest, a limiting groove is opened in the groove of the gun body, and the A limit screw with one end protruding out of the groove of the gun body is screwed in the limit groove; the end of the gun body in front of the knife rest is connected with a semicircular buckle with an opening downward, and the upper part of the buckle is connected with the gun body end. Head hinged. The knife holder is hinged in the grooved gun body, and the blade at the end of the knife holder can cut downwards by pulling the angle between the knife holder and the handle. The limit groove in the groove shape of the gun body can ensure that the rear part is not hindered when the knife rest rotates, and the limit screw can adjust the rotation angle of the knife rest, thereby controlling the cutting depth of the blade at the end of the knife rest. The end of the gun body is hinged with a semicircular buckle, which can be stuck on the outside of the optical cable and plays the role of fixing the position of the electrician's knife. When the outer skin of the optical cable needs to be cut longitudinally, the semicircular buckle is kept perpendicular to the gun-shaped frame and is stuck. For the outer sheath of the optical cable, when it is necessary to cut the outer sheath of the optical cable circularly, twist the buckle 90° and clamp the outer sheath of the optical cable.

The blade is a wallpaper knife blade. The tip of the blade is mainly used to cut the sheath of the optical cable. Using the wallpaper knife blade can break off the tip part by section after the tip of the knife is worn, and make full use of the tip of each section to cut the sheath. A return spring is connected between the other end of the knife rest and the handle. Return spring can reset knife rest.

The invention has the following advantages: 1. The structural design is ingenious, and the cutting depth can be controlled to ensure that the internal optical fiber will not be damaged; 2. The work efficiency is greatly improved, and the outer sheath of the optical cable can be cut longitudinally and circularly; 3. The operation is simple, fast, safe, and easy It will accidentally injure the operator.

detailed description

The portable gun-shaped electrician's knife includes a gun-shaped frame body, and the frame body is composed of a groove-shaped gun body 1 with an opening downward and a grip handle 2 fixed on the right end of the gun body 1; Knife rest 3, the bending part of described knife rest 3 is hinged with gun body 1, and one end of described knife rest 3 keeps parallel with gun body 1 in the groove shape of gun body 1 and leaves gap, and described knife rest 3 This end is fixed with the blade 4 with the cutting edge downward, and the other end of the knife rest 3 forms an angle with the grip handle 2; Open the limit groove inside, and in the limit groove, a limit screw 6 with one end protruding from the groove shape of the frame of the gun 1 is screwed; buckle 7, the top of the buckle 7 is hinged with the gun body 1 end.

During specific implementation, the blade 4 is a wallpaper knife blade. A return spring 5 is connected between the other end of the knife rest 3 and the handle 2 .

When in use, adjust the limit screw 6 to control the cutting depth of the tip of the blade 4 according to optical cables with different diameters and sheath thicknesses, and then adjust the buckle 7 to be perpendicular to the gun body 1, and the buckle 7 is stuck on the sheath of the optical cable , Pull the angle between the knife holder 3 and the handle 2, then hold the handle 2 tightly, pull the present invention along the axial direction of the optical cable, and the blade 4 can cut an axial slit on the outer skin of the optical cable. Then the buckle 7 is rotated 90°, and then the cable sheath is clamped, and the angle between the knife holder 3 and the handle 2 is pulled, the handle 2 is held tightly, and the circular rotation of the optical cable is made, the blade 4 can be placed on the cable sheath. Cut circular slits. Such two slits can successfully peel off the outer sheath of the optical cable without damaging the internal optical fiber.
