Description

A kind of duplex arm bolt clipper

Technical field

The utility model relates to the technical field of hardware & tools, refers to a kind of bolt clipper especially.

Background technology

Bolt clipper is mainly made up of cutter head, joint arm and handle, and cutter head and joint arm are interconnected by screw, and handle is arranged on the end of joint arm, and two cutter heads are movably connected by bolt by two clamping plate, and two joint arms are also interconnected by screw.Its operation principle is: when needing to shear object, open two handles and joint arm, two cutter heads also and then open, and between cutting edge object being put into two cutter heads, then firmly close, two cutter heads also and then close up, until cut off by reinforcing bar.Due to said structure, although joint arm has certain leverage, can reach labour-saving function, when shearing thicker object, operator needs larger strength, and operation is extremely required great effort.

Utility model content

Technical problem to be solved in the utility model is: provide one can labour-saving duplex arm bolt clipper more.

For solving the problem, the technical solution adopted in the utility model is: a kind of duplex arm bolt clipper, comprise the upper cutter head being positioned at front end, lower cutter head and the upper handle and the lower handle that are positioned at rear end, upper cutter head and lower cutter head are movably connected by two clamping plate and bolt, also comprise front upper joint arm, front lower joint arm, rear upper joint arm and rear lower joint arm, front upper joint arm and front lower joint arm are hinged, rear upper joint arm and rear lower joint arm are hinged, the rear end of described upper cutter head and the front end of front upper joint arm are hinged, the rear end of lower cutter head and the front end of front lower joint arm are hinged, the rear end of front upper joint arm and the middle part of rear upper joint arm are hinged, the rear end of front lower joint arm and the middle part of rear lower joint arm are hinged, upper handle is arranged on the rear portion of rear upper joint arm, lower handle is arranged on the rear portion of rear lower joint arm.

Preferably, the sidepiece of described rear upper joint arm is provided with adjustment screw, and adjustment screw is inconsistent with the inwall of rear lower joint arm after penetrating rear upper joint arm.

The beneficial effects of the utility model are: above-mentioned duplex arm bolt clipper, by the structure of duplex arm, defines second lever active force, and when shearing thicker object, operator can save required strength, easy and simple to handle.

Detailed description of the invention

Below by specific embodiment, a kind of duplex arm of one described in the utility model bolt clipper is described in further detail.

As Fig. 1, shown in Fig. 2, a kind of duplex arm bolt clipper, comprise the upper cutter head 1 being positioned at front end, lower cutter head 2 and the upper handle 3 and the lower handle 4 that are positioned at rear end, upper cutter head 1 and lower cutter head 2 are movably connected by two clamping plate 5 and bolt 6, also comprise front upper joint arm 7, front lower joint arm 8, rear upper joint arm 9 and rear lower joint arm 10, front upper joint arm 7 and front lower joint arm 8 are hinged, rear upper joint arm 9 and rear lower joint arm 10 are hinged, the rear end of described upper cutter head 1 and the front end of front upper joint arm 7 are hinged, the rear end of lower cutter head 2 and the front end of front lower joint arm 8 are hinged, the rear end of front upper joint arm 7 and the middle part of rear upper joint arm 9 are hinged, the rear end of front lower joint arm 8 and the middle part of rear lower joint arm 10 are hinged, upper handle 3 is arranged on the rear portion of rear upper joint arm 9, lower handle 4 is arranged on the rear portion of rear lower joint arm 10.

Preferably, the sidepiece of described rear upper joint arm 9 is provided with adjustment screw 11, and adjustment screw 11 is inconsistent with the inwall of rear lower joint arm 10 after penetrating rear upper joint arm 9.The opening and closing degree between rear upper joint arm 9 and rear lower joint arm 10 can be regulated by adjustment screw 11, thus regulate the closure of this doubly-linked arm bolt clipper.

Operation principle of the present utility model is: during use, operator's both hands force upper handle 3 and lower handle 4 outside, cutter head 1 and lower cutter head 2 are opened, object is placed between upper cutter head 1 and lower cutter head 2, inwardly closed upper handle 3 and lower handle 4, rear upper joint arm 9 and rear lower joint arm 10 are synchronously inwardly closed, the rear end of front upper joint arm 7 and front lower joint arm 8 is driven inwardly to close, front upper joint arm 7 and front lower joint arm 8 are rotated with pin joint, namely the front end of front upper joint arm 7 and front lower joint arm 8 is outwards opened, in drive, the rear end of cutter head 1 and lower cutter head 2 is outwards opened, upper cutter head 1 and lower cutter head 2 rotate with bolt 6, the front end of namely going up cutter head 1 and lower cutter head 2 inwardly closes, by object pinch off.It, by the structure of duplex arm, defines second lever active force, and when shearing thicker object, operator can save required strength, easy and simple to handle.

The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
