Abstract

The cable with stripping pliers includes handle and blade as well as characterized holding hook, pressure spring, regualting screw nut and feeder inside the handle. The holding hook, the pressure spring and the regulating screw nut are set successively in the lower part of the handle and the holding hook can move freely relative to the handle. The present invention has the advantages of simple operation and high efficiency, and can be used in radial cutting, spiral cutting and longitudinal cutting with controlled cut depth and is suitable for cutting and stripping cable wires of different diameters and different insulating layer thickness.

Description

Cable wire stripper

The invention relates to a cable stripper, in particular to a cable stripper which is suitable for cables with different diameters and can control the cutting depth and direction.

In electrical installation, the commonly adopted wire stripper for stripping the outer skin of the cable is generally completed by two blades fixed on a jaw, the structure is not easy to master the stripping depth, the excessive force can cut copper wires to damage insulation, the small force can not strip the cable skin because of incomplete cutting, the work efficiency is influenced, the function is single, and the use is not convenient enough.

The invention aims to provide a cable wire stripper which can be suitable for cutting different diameters, different insulating layer thicknesses and different cutting directions and can control the cutting depth.

The technical scheme of the invention is as follows: a cable wire stripper comprises a clamp handle, a blade, and is characterized by further comprising a clamping hook, a pressure spring, an adjusting nut and a feeding device arranged in the clamp handle, wherein the clamping hook, the spring and the adjusting nut are sequentially arranged at the lower part of the clamp handle, and the clamping hook can freely move up and down relative to the clamp handle; wherein,

the bottom of the clamping hook and the lowest part of the clamp handle opposite to the clamping hook are respectively provided with a V-shaped groove;

the outer surface of the clamp handle is provided with a plurality of V-shaped grooves;

the feed device also comprises a fine adjustment nut which can accurately master the feed depth.

The invention has the advantages of quick and convenient use and high working efficiency, can realize radial cutting, can realize spiral cutting and longitudinal cutting only by simple rotation, can control the cutting depth, and is suitable for cutting and stripping cables with different diameters and different insulating layer thicknesses.

The invention is further illustrated by the following examples in connection with the accompanying drawings.

Fig. 1 is an external view of the present invention.

Fig. 2 is a cross-sectional view of the present invention.

Fig. 3 is a cross-sectional view a-a of the present invention.

Fig. 4 is a detail of the pawl of the present invention.

As shown in figure 1, the lower part of the clamp handle 1 is sequentially provided with a clamping hook 2, a spring 3 and an adjusting nut 4, the clamping hook 2 can freely move up and down relative to the clamp handle 1 (the clamping hook cannot freely rotate under the action of a V-shaped groove 16 and a screw 14), and thus the clamping hook can be adjusted to adapt to cables with different diameters. The pressure spring 3 is pressed between the clamping hook 2 and the adjusting nut 4, and provides the clamping hook 2 with a proper clamping force for clamping the cable. The adjusting nut 4 is screwed on the forceps handle 1, the relative position of the forceps handle 1 and the clamping hook 2 is adjusted according to different cable diameters, and a V-shaped groove is respectively arranged at the bottom of the clamping hook 2 and the lowest part of the forceps handle 1 opposite to the clamping hook, and is used for clamping a small-diameter cable during cutting. The outer surface of the clamp handle 1 is provided with a plurality of longitudinal V-shaped grooves, the clamp handle 1 is rotated to change the relative position of the clamp handle and the clamping hook 2, and the clamp handle is tightly propped by a screw 14, so that circumferential cutting, spiral cutting and longitudinal cutting can be realized. As shown in figure 1, the position is radial cutting, the forceps handle can be longitudinally cut and peeled by rotating 90 degrees, and can be spirally cut and peeled by rotating a smaller angle.

As shown in fig. 2, the holder 1 has a feeding means, and an insert 13 (a general wallpaper insert, commercially available) is fixed to the holder 10, and a protruding insert hanging post 17 is provided on the lower portion of the holder 10, and the insert 13 is hung thereon. Two pawls 12 are mounted at the lower end of the push rod 11, the pawls 12 are opened by a thin spring wire 15, the push button 5 is twisted on the push rod 11 by a thin thread, and the cutter holder 10 is pushed to drive the blade 13 to move downwards by pressing the push button 5.

The fine adjustment nut 6 is connected with the push rod 11 through threads, and the push rod 11 can be pushed to move up and down by rotating the fine adjustment nut 6. When the blade 13 is brought into contact with the stripped cable, the feed depth can be accurately grasped by rotating the fine adjustment nut 6.

The pressing sleeve 9 is fixed on the clamp handle 1 by a puller screw 8, the puller screw 8 is loosened, and the pressing sleeve 9 is taken out, so that the tool holder 10 can be taken out to replace a new blade. The dull-ground blade can be pinched off gradually without grinding.

The feed device is fixed to the handle 1 by two sets of screws as shown in fig. 3.

The clamp handle 1 and the clamping hook 2 can be made of hard aluminum alloy, and the tool holder 10 is preferably made of engineering plastics.

When the pliers are used, a cable is placed in the clamping hooks, the cutting direction is adjusted, the adjusting nut 4 is rotated to enable the lower end of the pliers handle to be in contact with the cable and apply appropriate pressure, the cable is clamped in a cavity formed by the upper V-shaped groove and the lower V-shaped groove, the pressing button 5 is pressed to enable the blade to be in contact with the cable, the nut 6 is finely adjusted through the knob to obtain an appropriate cutting and stripping depth, when the pliers are used, the cable with a large diameter and good rigidity is cut in a circumferential direction or a spiral direction, and the cable with a small diameter and poor rigidity is cut and stripped in a longitudinal direction.
