Description
Technical field
The invention belongs to hardware & tools technical field, particularly to a kind of bolt clipper.
Background technology
Bolt clipper is generally used for shearing the metal wire rod that diameter is less, and traditional bolt clipper includes two pieces of folders being oppositely arranged
Plate, is provided with two mutually opposing cutter heads between two clamping plate, two cutter heads are hinged by first bearing pin and two clamping plate respectively,
Two cutter head front portion opposite sides are respectively symmetrical blade, and there are pincers two cutter head rear ends by second hinge respectively
Handle, the front end of two clamp handles is provided with the support arm extended towards, and two Arm portion are overlapping and lap is by the 3rd bearing pin
Hinged, during use, manually open two clamp handles, now two clamp handles rotate around the 3rd bearing pin, and the rotation of clamp handle drives second
Bearing pin rotates, and the second bearing pin drives the rear end of two cutter heads mutually to draw close, and two cutter heads rotate rotating around corresponding first bearing pin, two cutter heads
Blade be separated from each other, after metal wire rod snaps between two blades, manual closing two clamp handle, two cutter heads the most gradually close up, directly
Cut off to by metal wire rod.
The cutter head of tradition bolt clipper can be considered a lever with the first bearing pin as fulcrum, and clamp handle can be considered as one with the
Three bearing pins are the lever of fulcrum, by the combination of two levers, form second lever, are greatly exaggerated the lever ratio of entirety,
Although by the structure of current second lever, being greatly enhanced the shearing force between two blades, reduce shearing metal wire
Be applied to the power in two clamp handles required for material, but current bolt clipper in use required for the power that is applied in clamp handle the most very
Greatly, one man operation, it is difficult to long lasting for work.
Summary of the invention

Detailed description of the invention
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
Bolt clipper as shown in Figure 1, including two pieces of clamping plate being oppositely arranged 1, has been arranged side by side two phases between two clamping plate 1
The most opposed cutter head 2, two cutter heads 2 are hinged with two clamping plate 1 by first bearing pin 3 respectively, and the anterior opposite sides of two cutter heads 2 is respectively
Being provided with blade 4, two cutter head 2 rear ends are hinged with clamp handle 6 by second bearing pin 5 respectively, and the front end of two clamp handles 6 is provided with phase
To the support arm 7 extended, two support arms 7 partly overlap and lap is hinged by the 3rd bearing pin 8, described cutter head 2
On be provided with and the first bearing pin 3 arc-shaped hole 11 one to one, described first bearing pin 3 is arranged in described arc-shaped hole 11,
And can slide along arc-shaped hole 11 length direction, the arc core 18 of described each arc-shaped hole 11 same point between two cutter heads 4,
The distance between the second bearing pin 8 and the first bearing pin 3 on same cutter head 2 is less than the distance between the second bearing pin 8 and arc core 18.Institute
State arc core 18 between the first bearing pin 3 and blade 4.When rotation blade 2, cutter head 2 is at arc-shaped hole 11 and the first bearing pin 3
Rotating around arc core 18 under constraint, if cutter head 2 is regarded as lever, then arc core 18 is fulcrum.
In order to prevent cutter head 2 around the first bearing pin 3 rotation, two cutter heads 2 are caused to produce dislocation, it is also possible to by the first bearing pin 3
Cross section is arranged to length and is more than kidney-shaped or the Long Circle of arc-shaped hole 11 width.
Described arc-shaped hole 11 is arranged on cutter head 2, keeps the attractive in appearance of bolt clipper profile, is more prevented from dust and enters folder
Gap between plate 1 and cutter head 2, except being arranged on arc-shaped hole 11 on cutter head 2, it is also possible to arc-shaped hole 11 is arranged on folder
On plate 1.
As in figure 2 it is shown, as the improvement to technique scheme, be additionally provided with one between described two clamping plate 1 and be parallel to
The straight pin 9 of the first bearing pin 3, this straight pin 9 is concentric with arc core 18, and the two ends of straight pin 9 are connected on two clamping plate 1, and two
The groove 10 matched with straight pin 9 lateral wall, the sidewall that described straight pin 9 is relative with two cutter heads 2 it is respectively arranged with on cutter head 2
It is respectively embedded in two grooves 10, efficiently avoid cutter head 2 and produce the situation of dislocation.
As it is shown on figure 3, the power arm A that traditional bolt clipper is formed on cutter head 2 be the second bearing pin to the first bearing pin away from
From, resistance arm B is first bearing pin distance to metal wire rod 17, lever ratio M=A/B, as shown in Figure 4, due to of the present invention
The fulcrum of bolt clipper be arc core 18, the power arm a therefore formed on cutter head is second bearing pin 5 distance to arc core 18, resistance
Arm of force b is the arc core 18 distance to metal wire rod 17, and lever ratio is m=a/b, owing to arc core 18 is between two cutter heads 2, and position
Between the first bearing pin 3 and blade 4, therefore resistance arm b is less than resistance arm B, and power arm a is more than power arm A, and its result is thick stick
Bar is than m more than lever ratio M, and bolt clipper the most of the present invention, in the case of the lever ratio of clamp handle 6 is identical, breaks than tradition
Clamp more laborsaving.
Insert as it is shown in figure 5, be respectively arranged with a cylinder matched with straight pin 9 on described two clamping plate 1 forward surfaces
Groove 12, the two ends of described straight pin 9 are inserted in the slot 12 on two clamping plate respectively, so can be hidden straight pin 9, it is also possible to letter
Change the installation of straight pin 9.
Described straight pin 9 is fixedly connected in the groove 10 on a cutter head 2, the groove 10 on another cutter head 2 and circle
Pin 9 sidewall offsets, and reduces scattered number of parts, improves efficiency of assembling.
As it is shown in figure 5, be respectively arranged with, between described cutter head 2 and two clamping plate 1, the wear-resistant plastic being socketed on the first bearing pin 3
Packing ring 13, the characteristic of wear-resistant plastic packing ring is to have certain elasticity and extremely low coefficient of friction, can improve clamping plate 1 and cutter head 2
Between motility in relative rotation.
As described in Figure 1, the axle center of described 3rd bearing pin 8 is positioned on the axis of symmetry of two second bearing pins 5.
As it is shown in figure 1, described clamp handle 6 tail end is arranged with sleeve 14, sleeve 14 is provided with rough anti-skidding lines
15, stability during hand-held clamp handle 6 can be improved；Sleeve 14 tail end is additionally provided with hanging hole 16, when bolt clipper leaves unused when, permissible
Hang on wall, convenient for collecting.
The operation principle of the present invention is: when utilizing bolt clipper of the present invention to carry out shearing metal wire rod 17, cutter head 2
Rotate with arc core 18 for fulcrum, owing to the position of arc core 18 is arranged in the middle of two first bearing pins 3, with tradition bolt clipper phase
Ratio, the power arm a of bolt clipper of the present invention is longer, and resistance arm b is shorter, and lever ratio m of cutter head 2 entirety is bigger, because of
This, when shearing metal wire rod 17, more laborsaving than traditional bolt clipper.
