Abstract

The utility model relates to a pair of multifunctional mechanical shears for cutting wires, which is composed of a cutter frame rotary shaft, a fixed cutter frame, a left blade, a right blade, a rotary cutter frame, eccentric propelling teeth, an eccentric bracket, a stopper, a right hand toggle handle, a left handle, a left hand toggle handle, a splicing screw cap, a right handle, and positioning devices for the handles, wherein, the fixed cutter frame and the rotary cutter frame are provided with dismountable cutting blades with double cutting edges. A group of simple positioning devices which are composed of annular grooves and springs are arranged in the left and the right hand toggle handles. The utility model can be used for cutting cable wires, steel core cables, steel wire cables and low carbon round steel, and gained cross sections are basically round. The utility model has the advantages of artful structure, light weight, small size, simple operation, portability, large shearing force, etc., and is an ideal tool for electric and mechanical execution.

Description

Multi-functional mechanical formula conductor cutter

The utility model relates to a kind of multi-functional mechanical formula conductor cutter that cuts off cable, steel core cable, flexible steel wire, low-carbon (LC) unit steel that is mainly used in.

Domestic prior mechanical conductor cutter adopts the Bars rod principle, and volume is big, and is very heavy, only adapts to cut off general cable; That supplies on the market cuts energetically, and except that heaviness, the scope of application is also very held under the arm narrow, the first steel of a little low-carbon (LC)s that can only break.The two is all powerless to the cut-out of steel core cable and flexible steel wire.Also have a kind of mechanical type conductor cutter abroad, smaller and more exquisite, but also only be suitable for the cut-out of general lead and cable.Though its inside has gear graduation to change force mechanisms, because of it does not have detachable double blade blade, can't implement to cut off to steel core cable, flexible steel wire, low-carbon (LC) unit steel, in case the edge of a knife is blunt, also can only whole scissors be scrapped.

The purpose of this utility model has provided a kind of small and exquisite, can cut off the multi-functional mechanical formula conductor cutter that cable, steel core cable, flexible steel wire, low-carbon (LC) do not have steel.

Scheme of the present utility model is to realize like this.

It is by knife rest rotating shaft, immovable support, left blade, right blade, rotating turret, the eccentric tooth that advances, eccentric stent, retainer, right hand toggle, left handle, the left hand toggle is pieced together tight nut, and right handles and handle positioner are formed, and positioner is made up of a plurality of cannelures and spring.Left blade wherein is to be fixed on the immovable support by screw, and right blade is to be fixed on the rotating turret by screw, and rotating turret is to socket-connect with the knife rest rotating shaft, there is the eccentric tooth that advances the right handles upper end, there is eccentric stent inside, and right handles is with right hand toggle outward, and left handle is with the left hand toggle outward, the left hand and right hand toggle all is provided with pieces together tight nut and handle positioner, and the handle positioner is made up of a plurality of cannelures and spring.Gu second end sideline profile of tooth and the retainer kissing of movable knife rack connect.

Below preference in conjunction with the accompanying drawings the utility model is elaborated, Fig. 1 is the utility model multi-functional mechanical formula conductor cutter sketch, stirs rotating turret (5), and the workpiece of desire cut-outs is placed left and right blade (3,4) centre.The moving right handles (14) of plate by eccentric stent (7), drives the eccentric tooth (6) that advances then, rotating turret (5) and blade (4) is rotated, (its structure is same as the prior art with principle) to the center.Right handles (14) repeats repeatedly to pull, and progressively realizes cut-out work, up to cutting workpiece.When desire realizes cutting off work for the second time, retainer (8) need only be pressed, rotating turret (5) just energy freely rotates for 360 °.Rotating turret (5) is stirred in retainer (8) displacement, can begin the work of cut-out for the second time.Go round and begin again, can carry out cutting work respectively.

If it is bigger to be cut off workpiece, can draw back right hand toggle (9) and left hand toggle (11), new cannelure 13a is enclosed within on the spring 13b, can change big operational torque like this, use laborsaving.Handle location structure (13) can prevent the disengaging of left and right gloves handle (9,11) and left and right handle (10,14).

Blade (3) (4) by trip bolt (16,15), is fastened on immovable support (2) and the rotating turret (5) respectively, and is blunt as blade, and detachable the replacing is also detachable after use is loaded onto in grinding again.The section that is cut off workpiece is circular substantially.

The utility model has the advantages that and can cut off bigger cable such as steel core cable, flexible steel wire etc., is electricity In gas, the mechanical execution, realize the ideal tools of particular range rupturing operation.

Claims

1. multi-functional mechanical formula conductor cutter, it is characterized in that: by knife rest rotating shaft (1), immovable support (2), left side blade (3), right blade (4), rotating turret (5), the eccentric tooth (6) that advances, eccentric stent (7), retainer (8), right hand toggle (9), left handle (10), left hand toggle (11), piece together tight nut (12), handle positioner (13) and right handles (14) are formed, left blade (3) wherein is to be fixed on the immovable support (2) by screw (16), and right blade (4) is to be fixed on the rotating turret (5) by screw (15), and rotating turret (5) is to socket-connect with knife rest rotating shaft (1), and there is the eccentric tooth (6) that advances right handles (14) upper end, and there is eccentric stent (7) inside, the outer right hand toggle (9) that is with of right handles (14), outer left hand toggle (11), the left side of being with of left handle (10), right hand toggle (11,9) all has the tight nut (12) of assembly and handle positioner (13), and handle positioner (13) is made up of a plurality of annular solid grooves (13a) and spring (13b), and second end sideline tooth pattern of immovable support (2) and retainer (8) kissing connect.
