Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present utility model 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
Mutually 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 head 2 are respectively
It is provided with blade 4, two cutter head 2 rear end is 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 extending, 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 one-to-one arc-shaped hole 11 of the first bearing pin 3, 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 is located at the same point between two cutter heads 2,
The distance between the second bearing pin 8 on same cutter head 2 and the first bearing pin 3 are less than the distance between the second bearing pin 8 and arc core 18.Institute
State arc core 18 to be located between the first bearing pin 3 and blade 4.When rotation blade 2, cutter head 2 is in arc-shaped hole 11 and the first bearing pin 3
Rotate around arc core 18 under constraint, if cutter head 2 is regarded as lever, arc core 18 is fulcrum.
In order to prevent cutter head 2 around the first bearing pin 3 rotation, two cutter head 2 is led to produce dislocation, can also be by the first bearing pin 3
Cross section is arranged to kidney-shaped or the Long Circle that length is more than 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
Arc-shaped hole 11, except being arranged on arc-shaped hole 11 on cutter head 2, can also be arranged on folder by the gap between plate 1 and cutter head 2
On plate 1.
As shown in Fig. 2 as the improvement to technique scheme, be additionally provided between described two clamping plate 1 one 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 being matched with straight pin 9 lateral wall, the described straight pin 9 side wall relative with two cutter heads 2 are respectively arranged with cutter head 2
It is respectively embedded in two grooves 10, efficiently avoid the situation that cutter head 2 produces dislocation.
As shown in 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 the distance to metal wire rod 17 for first bearing pin, lever ratio M=A/B, as shown in figure 4, due to this utility model
The fulcrum of described bolt clipper is arc core 18, the power arm a being formed therefore on cutter head be the second bearing pin 5 arrive arc core 18 away from
Be the distance that arc core 18 arrives metal wire rod 17 from, resistance arm b, lever ratio is m=a/b, due to arc core 18 be located at two cutter heads 2 it
Between, and be located 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, its
Result is more than lever ratio M for lever ratio m, and bolt clipper therefore described in the utility model is in the lever ratio identical situation of clamp handle 6
Under, more laborsaving than traditional bolt clipper.
As shown in figure 5, a cylinder being matched with straight pin 9 is respectively arranged with described two clamping plate 1 forward surface inserting
Groove 12, the two ends of described straight pin 9 are inserted in the slot 12 on two clamping plate respectively, so can hide 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, groove on another cutter head 2 10 and circle
Pin 9 side wall offsets, and reduces scattered number of parts, improves efficiency of assembling.
As shown in figure 5, being respectively arranged with the wear-resistant plastic being socketed on the first bearing pin 3 between described cutter head 2 and two clamping plate 1
Packing ring 13, the characteristic of wear-resistant plastic packing ring is that have certain elasticity and extremely low coefficient of friction, can improve clamping plate 1 and cutter head 2
Between the motility that relatively rotates.
As described in Figure 1, the axle center of described 3rd bearing pin 8 is located on the axis of symmetry of two second bearing pins 5.
As 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, permissible
Hang on wall, convenient for collecting.
Operation principle of the present utility model is：Carrying out shearing metal wire rod 17 using bolt clipper described in the utility model
When, cutter head 2 is rotated with arc core 18 for fulcrum, because the position of arc core 18 is arranged in the middle of two first bearing pins 3, breaks with tradition
Line tweezer is compared, and the power arm a of bolt clipper described in the utility model is longer, and resistance arm b is shorter, lever ratio m of cutter head 2 entirety
Then bigger, therefore, during shearing metal wire rod 17, more laborsaving than traditional bolt clipper.
