Furthermore, the cutting edge design of the present invention allows the shear force to be directly transmitted to achieve the effort-saving effect. The first plier body and the second plier body can be made of 3.5mm metal plate, so that the angle of the cutting edge design under the pivot member is conducive to the grinding process, and greatly reduces the grinding cost, prevents stab wounds, and increases the shear force, thereby achieving the purpose of cutting the steel cable and the riveted aluminum wire tail sleeve.

Description

Wire rope cutter

The present invention relates to cutting tools, in particular to a wire cutter, the blade is set at the lower end of the pivot, and the design is conducive to the grinding process, and greatly reduces the grinding cost and increases the ability to cut the steel cable, safe and keep the steel cable section flat. In addition, the pivot has the function of clamping the thread tail sleeve. In addition, the thimble in the pivot can be manufactured and shaped by a punching screw heading machine, so that the product of the present invention can be produced quickly, reduce manufacturing costs, and increase profitability. Product advantages.

Check that the wire cutters currently used to cut steel ropes such as the Republic of China Patent No. M459957 and No. M540032. In addition to the function of cutting steel cables, this type of thread cutter can also be used through the central pivoting piece. The inner top pin is clamped to the tail sleeve, so that the steel cable is combined with the tail sleeve.

However, the conventional device has the following disadvantages:

1. The sharp pliers mouth is set on the top of the pliers body. If the user is not careful or is looking for a tool, it is easy to be stab wound. This type of design should be avoided to prevent work safety accidents.

2. The pliers mouth is too far away from the pivot axis in the middle, instead it enlarges the distance of the arm of force, and cutting the steel cable requires a large force. When the steel cable is cut, the rebound force generated is strong, which makes the user inconvenient to use.

3. Accept the foregoing, because the jaws of the pliers enlarge the distance of the arm of the force, the shearing force is not smooth, and it is easy to cause the cross section of the steel cable after being cut to be uneven.

4. There is a block in the center of No. M459957 that can clamp the tail sleeve. By rotating the clamp body, the pressing piece can be clamped to the thread bushing. However, the special shape of the pressing piece must be manufactured through powder metallurgy. The manufacturing cost is high and the powder metallurgy products inherently have the lack of excessive strength, so the compression piece is easy to break and damage.

5. Because the force arm of the pliers mouth of the aforementioned case is too long, the thickness of the pliers body must be increased in the design. After measurement, the thickness of the pliers body in the previous case must be at least 4 mm or more, but the manufacturer’s manufacturing has also been added virtually. Cost and product weight add intangible costs to subsequent packaging and transportation.

How to improve the lack of conventional technology is a subject of active development for related industries.

The main purpose of the present invention is to provide a cable cutter, the detailed structure of which includes a first pliers body and a second pliers body, a fixing piece, a pivot member, and three abutting modules; The first pliers body is provided with a first grip, a first cutting edge, and a first coupling plate from bottom to top. The center of the first coupling plate is provided with a pivot end, and the first pivot end is used as the center and radially arranged Three L-shaped fixed ends, and three radially arranged screw holes are provided on the first joint plate; the aforementioned second pliers body is sequentially provided with a second grip, a second cutting edge and A second connecting plate, a three-leaf connecting part is arranged in the center of the second connecting plate, and the connecting part can define three guiding areas. In addition, the outer side of the connecting part is provided with radially arranged guiding edges; The pivot member penetrates the first pliers body, the second pliers body, and the fixing piece, so that the first pliers body and the second pliers body produce a shearing action, and the opposite first cutting edge and the First The two cutting edges form the jaws for cutting the steel cable and are arranged below the pivot member. The center of the pivot member is a hollow cylindrical structure. The direction of the pivot member is the axis, and it is on the radial wall. Three perforations are provided; the aforementioned abutment modules all include a thimble and a spring, the thimble has a cap and a needle, the spring is sleeved on the needle, the needle penetrates the through, the cap There is a joint area to be combined with the L-shaped fixed end of the first pliers body, and the cap part abuts against the guide area of the second pliers body; the fixing piece is arranged on the second joint of the second pliers body The board is provided with three straight holes through three screws respectively penetrated into the straight holes, and the aforementioned screws behind the guide edges are screwed to the screw holes of the first coupling board.
