Description

Clamp belt shearing pliers

Technical Field

The utility model belongs to the technical field of the aviation is made and is maintained, a clamp is sheared pincers is related to.

Background

Some cables need to be disassembled during maintenance of the aircraft. In the process of disassembling the cables, since bundled cables are usually bundled with a clamping band, the clamping band is first cut off with diagonal pliers. The cable and the clamping belt are tightly bound, the insulating layer outside the cable is very thin, the thickness and the binding angle of a single cable inside a cable harness are different, the direction of the cable and the clamping belt cannot be guaranteed to be perpendicular to each other, meanwhile, the cutting edge of the diagonal pliers must exceed the inner side face of the clamping belt to cut the cable, and therefore the cutting edge of the diagonal pliers easily touches the cable in the cutting process of the clamping belt in actual operation to damage the cable.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a clamp shears pincers, can cut the cassette that ties up the cable through simple operation, can not injure the cable that the cassette was tied up simultaneously.

The technical scheme of the utility model is that:

a kind of clip ribbon cutting nippers, including hand grip, spindle 5 and jaw.

The handles comprise a handle a1 and a handle b2, and the jaws comprise a jaw a3 and a jaw b4; the handle a1 and the jaw a3 form an integrated clamp body structure, the handle b2 and the jaw b4 form an integrated clamp body structure, and the two clamp body structures are in an axisymmetric structure and are connected together through a rotating shaft 5 to form a rotatable structure.

The end surfaces of the jaw a3 and the jaw b4 are in a parallel and smooth state, the opposite surfaces of the inner sides of the jaw a3 and the jaw b4 are cutting edges, and the front end of each cutting edge is provided with a half groove; when the jaw a3 and the jaw b4 are clamped, the cutting edges are in a completely attached state, a complete groove 6 is formed at the front end of each cutting edge at the moment, the width of each groove 6 is 2.5-5 mm, and the length of each groove 6 is 2-3 times of the width. The edges of the cutting edges are all chamfered with 0.3mm round angles.

The outer end surface 8 of the jaw is 10-25 degrees to the axis of the tool whole body, and the inner end surface 7 of the jaw is 3-5 degrees to the axis of the tool whole body.

Furthermore, 6 length of recess of cutting edge front end of cutting nipper are 2.5 times of width, and this kind of proportion just in time can restrict the length that the tip of keeping silent deepened in the cable conductor, can enough guarantee to keep silent the interior sword and effectively cut the cassette, also can guarantee simultaneously when keeping silent the degree of depth to the cable conductor, can excessively not produce the extrusion to the cable, prevent the cable insulation damage.

Further, the outer end face 8 of the jaw is 15 degrees with the whole axis of the tool, the inner end face 7 of the jaw is 3 degrees with the whole axis of the tool, the convenience that the tool can be more suitable for the operation on the machine in the operation process can be guaranteed, and the angle is more favorable for the use of normal operators.

The utility model has the advantages that:

(1) The utility model has the advantages of simple structure is small and exquisite, and specially adapted cassette is cut off on the aircraft.

(2) The utility model has the advantages of simple structure firmly, not fragile and can use by high frequency.

Detailed Description

The following embodiments of the present invention will be further explained with reference to the accompanying drawings, but the present invention is not limited thereto.

The utility model provides a clamp belt shears pincers, can cut the cassette belt of tying up the cable through simple operation, can not injure the cable that the cassette belt tied up simultaneously. The clamping band cutting pliers comprise handles, rotating shafts 5 and jaws.

The handle comprises a handle a1 and a handle b2, and the jaw comprises a jaw a3 and a jaw b4; the handle a1 and the jaw a3 form an integrated clamp body structure, the handle b2 and the jaw b4 form an integrated clamp body structure, and the two clamp body structures are in an axisymmetric structure and are connected together through a rotating shaft 5 to form a rotatable structure.

The end surfaces of the jaw a3 and the jaw b4 are in a flush and smooth state, the opposite surfaces of the inner sides of the jaw a3 and the jaw b4 are cutting edges, and the front end of each cutting edge is provided with a half groove; keep silent a3 and keep silent b4 when pressing from both sides tightly, the blade is the laminating state completely, and the front end of blade forms a complete recess 6 this moment, and the width of recess 6 is 2.5mm, and the length of recess is 2.5 times of width. And 0.3mm round corners are all chamfered at the edges of the tool cutting edges.
