Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 7, a cable stripper includes a first clamping plate 11 and a second clamping plate 12 which are elastic, and an elastic portion 13 which connects the first clamping plate 11 and the second clamping plate 12 into a U-shaped structure, wherein the elastic portion 13 is a torsion spring or a plate spring; this U-shaped configuration facilitates clamping and spreading.

The first clamping plate 11 and the second clamping plate 12 are symmetrically provided with two rotating shafts 2; the opposite end parts of the two rotating shafts 2 are fixed with arc plates 3; the arc plate 3 can rotate relative to the first clamping plate 11 and the second clamping plate 12 through the rotating shaft 2. Thereby the arc plate 3 is more suitable for the arc surface of the cable.

A first slotted hole 4, a second slotted hole 5, a third slotted hole 6 and a fourth slotted hole 7 which penetrate through the arc plate 3 are arranged in a cross shape by taking the rotating shaft 2 as the center, and the first slotted hole 4, the second slotted hole 5, the third slotted hole 6 and the fourth slotted hole 7 are strip-shaped through holes; the first slot 4 and the second slot 5 are arranged in the direction of the axis a of the arc plate 3, and the third slot 6 and the fourth slot 7 are arranged in the direction of the axis b of the arc plate 3.

A first pressing plate 41 and a first stop block 42 which form a T-shaped structure are arranged in the first slot hole 4;

a second pressing plate 51 and a second stop block 52 which form a T-shaped structure are arranged in the second slotted hole 5;

a third pressure plate 61 and a third stop block 62 which form a T-shaped structure are arranged in the third slot 6;

a fourth pressing plate 71 and a fourth stop 72 which form a T-shaped structure are arranged in the fourth slot hole 7;

the first stop block 42, the second stop block 52, the third stop block 62 and the fourth stop block 72 are respectively connected with the arc plate 3 through springs 8; the first stopper 42, the second stopper 52, the third stopper 62 and the fourth stopper 72 can be raised higher with respect to the arc plate 3 by the action of the spring 8.

A cutting knife 43 is fixed below the first pressing plate 41, and further, the cutting edge of the cutting knife 43 faces to the opposite direction of the rotating shaft 2; a pressing wheel 53 is connected with the lower part of the second pressing plate 51 through a shaft, and hard wheel pricks 54 are arranged on the outer edge of the pressing wheel 53; a cutting knife 63 is fixed below the third pressing plate 61; a saw blade 73 is fixed below the fourth pressing plate 71. By the depression of the wheel pricks 54, the metal armor can be easily pierced and left with uniform voids on the metal armor.

The working principle is as follows: when using the utility model discloses the time, need earlier when cutting open the plastic of cable outside, can let pivot 2 on rotatory first splint 11 and the second splint 12, ensure that first splint 11 and second splint 12 can extrude first dog 42. Then, the first clamping plate 11 and the second clamping plate 12 are clamped and slid along the path of the cable, namely, the direction a in fig. 2, so that the plastic skin on the outer part of the cable can be cut. If a thicker plastic skin is encountered, the rotating shaft can be rotated first to enable the first clamping plate 11 and the second clamping plate 12 to clamp the pressing wheel 53, and then the wheel pricks 54 can prick more holes on the plastic skin. Then, the plastic skin can be cut open at a time quickly by continuing to break open the plastic skin with the cutter 43.

When it is desired to circumferentially cut the cable sheath, the first clamping plate 11 and the second clamping plate 12 may be clamped against the third stop 62 or the fourth stop 72. The plastic skin is broken by the cutting edge of the cutter knife 63 or the saw edge of the saw knife 73.

For the inner metal armor, the cutting knife 63 and the saw knife 73 can be continuously used for cutting off the metal armor. Since the metal armor is generally helically wound around the cable, it can be peeled off directly by hand.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
