Abstract

The utility model relates to an improved cable cutter, which is suitable for cutting copper-aluminum armored cables and mainly comprises a fixed cutting board. The improved cable cutter is characterized in that the cutting edge of the fixed cutting board has a straight port shape; five indented R circular arcs are uniformly distributed at the circular arc portion of the straight port; the fixed cutting board is connected with a rotary cutting board via cutter frame pins; a tooth support block is fixed to the fixed cutting board via pins; a fixed handle is fixed to the fixed cutting board via fixing pins for a connecting block; a movable handle is connected with the fixed cutting board via an eccentric shaft seat board and a rotating shaft for a push block; the end portion of the push block is connected with arc support teeth via the rotating shaft; and teeth at the edge of arc support teeth are engaged with teeth at the edge of the rotary cutting board. With a reasonable integral structure, the improved cable cutter adopts unique knife-shape design and guarantees that the cross section of a cable cut is smoother and is not deviated and deformed after already used for a long period of time. The handle is flexibly stretched out and drawn back, and the structure of a locking unit can ensure that the handle is not likely to slip, so that the cutting operation is rapid and labor-saving during the practical construction. The improved cable cutter, with high practicability, is convenient to operate and easy to popularize and can be widely applied in the electric power industry, the traffic industry, the communication industry, the building industry and other industries.

Description

Improved cable is cut

Technical field:

The utility model relates to improved cable to be cut, and is applicable to shear copper aluminium armored cable, its compact conformation and sturdy and durable; Adopt unique cutter type design; Guarantee that the cut cable cross section is more smooth, handle scalable being difficult for skids, and both sheared brisk laborsaving; Be easy to carry again, be widely used in industries such as electric power, traffic, communication and building.

Background technology:

Along with the raising of industry such as electric power, traffic, communication and building to installation requirement, the user needs the smooth cable of shear surface to cut instrument and replaces cutting machine.After present cable was sheared cable, cable cross-section was sharp arc, and utmost point out-of-flatness causes in the construction and also will handle again end, and is flat with the hacksaw saw; In addition, easy skidding appears in the handle cut of cable in the constructing operation process.So still need further improve to existing cable shear structure, make that its structure is more reasonable, satisfy the demand on the market.

The utility model content:

The purpose of the utility model is to provide improved cable to cut, and can shear copper aluminium armored cable material, and its compact conformation and sturdy and durable adopts unique cutter type design, guarantees that cut cable is more smooth, and long-term use can not depart from distortion; In addition, also increase the handle inside that cable cuts and all be provided with locking device, can make the phenomenon that can not skid in the work progress, overcome the shortcoming and defect that exists in the prior art.

To achieve these goals; The technical scheme of the utility model is: improved cable is cut, and it mainly comprises fixedly knife plate, it is characterized in that: the edge of a knife of described fixedly knife plate is straight degree of lip-rounding shape; Straight mouthful of circular arc position is provided with five indent R circular arcs that are uniformly distributed with; Fixedly knife plate is connected with the rotation knife plate through the tool axis nail, and the edge of a knife of described rotation knife plate is the continuous helical line, and supporting tooth block is fixed on fixedly knife plate place through the axle nail; Fixed handle is fixed on fixedly knife plate place through connecing piece with steady pin; Flexible handle is connected with fixing knife plate with rotating shaft through eccentric shaft seat board and pushing block, and the end of pushing block is connected with rotating shaft and arc support tooth, and the teeth at arc support tooth edge and the teeth of rotating knife panel edges are meshing with each other.

The improved cable of the utility model is cut, and the product reasonable integral structure adopts unique cutter type design, guarantees to shear smooth, and telescopic handle is flexible, and locking device can guarantee that handle is non-slip, has very strong practicality, and is easy and simple to handle, is easy to apply.

Fig. 2 is the part-structure sketch map of the utility model

Fig. 3 is the edge of a knife shape enlarged diagram of the fixedly knife plate of the utility model

Among the figure: (1) fixedly knife plate (2) rotation knife plate (3) tool axis nail (4) supporting tooth block (5) axle nail (6) eccentric shaft seat board (7) arc support tooth (8) pushing block (9) rotating shaft (10) flexible handle (11) connects the outer steel pipe of the interior steel pipe of piece (12) fixed handle (13) steady pin (14) (15) (16) outer collar (17) rubber sheath (18) clamp ring (19) pin

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done following detailed description the in detail.

The utility model is that improved cable is cut, and like Fig. 1, Fig. 2, shown in Figure 3, it mainly comprises fixedly knife plate (1); It is characterized in that: the edge of a knife of described fixedly knife plate (1) is straight degree of lip-rounding shape; Straight mouthful of circular arc position is provided with five indent R circular arcs that are uniformly distributed with, and its shape and structure can guarantee that shear surface is smooth, and fixedly knife plate (1) is connected with rotation knife plate (2) through tool axis nail (3); The edge of a knife of described rotation knife plate (2) is the continuous helical line; Its shape and structure can make to be sheared laborsavingly, and supporting tooth block (4) is followed closely (5) through axle and is fixed on fixedly knife plate (1) and locates, and fixed handle (12) is fixed on fixedly knife plate place (1) through connecing piece (11) with steady pin (13); Flexible handle (10) is connected with fixing knife plate (1) with rotating shaft (9) through eccentric shaft seat board (6) and pushing block (8); The end of pushing block (8) is connected with arc support tooth (7) with rotating shaft (9), and the teeth at arc support tooth (7) edge are meshing with each other with the teeth at rotation knife plate (2) edge, and it adopts the ratchet-advance structure; Mechanical strength is high; Operating physical force is little, and described fixed handle (12) and flexible handle (10) are socketed to form by interior steel pipe (14), outer steel pipe (15), outer collar (16), rubber sheath (17) successively, is equipped with clamp ring (18) and pin (19) between the outer collar (16) of described fixed handle (12) and flexible handle (10) and the interior steel pipe (14); This kind locking device structure can stretch flexibly, occurs skidding in the time of can preventing constructing operation again.
