Abstract
The invention discloses a grading steel bar shear which comprises a base, a handle hinged to the top end of the base, a movable cutter and a fixed cutter, and the movable cutter and the fixed cutter are hinged to the front end of the base. The front end of the movable cutter and the front end of the fixed cutter are respectively provided with a U-shaped cutting edge used for shearing steel bars, a groove or a through hole is formed in the portion, close to the hinging portion to the top end of the base, of the handle, the rear end of the movable cutter is movably embedded in the groove or the through hole, the movable cutter and the fixed cutter are provided with through holes used for reducing weight, the front end and the rear end of the movable cutter are connected through a pin shaft, and the movable cutter and the fixed cutter are made of 50CrV.
Description
Technical field
The present invention relates to a kind of hand-operated tools, especially a kind of reinforced shear that cuts off reinforcing bar.
Background technology
Reinforced shear of the prior art is generally comprised of cutter hub and handle, and operation is painstaking, and the meeting of the cutter hub of this structure is because stressed reason easily be damaged, and greatly reduce the service life of product, has improved use cost.
Summary of the invention
Technical problem to be solved by this invention is: a kind of classification reinforced shear is provided, only need just can obtains good shear effect with less manpower, production efficiency is high, long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of classification reinforced shear, comprise base, with the hinged handle in base top, with the hinged movable segment distance of pivot point that described handle is set of base front end.
As a kind of optimal way, it is characterized in that, on described handle, near offering groove with hinged position, base top, the rear end of moving knife is flush-mounted in groove movably.
As a kind of optimal way, it is characterized in that, on described handle, near offering through hole with hinged position, base top, the rear end of moving knife is flush-mounted in through hole movably.
As a kind of further improvement, on described moving knife and stationary knife, offer lightening hole.
As a kind of optimal way, the front-end and back-end of described moving knife connect by bearing pin.
As a kind of optimal way, the material of described moving knife and stationary knife is 50CrV.
The invention has the beneficial effects as follows: in reinforced shear, adopt hierarchy setting, can in the situation that not changing decreased food, take lever principle as basis, change the pivot point position of handle, realize the object of gradation reinforcing, after can dividing several times reinforcing by a reinforcing bar, cut off, rapid operation, can obtain good bar cutting effect, and production efficiency is high; On moving knife and stationary knife, be provided with for alleviating the through hole of quality, make the oeverall quality of reinforced shear little, be convenient to transportation.
Accompanying drawing explanation
Fig. 1 is the structural representation of classification reinforced shear of the present invention;
In figure: 1, base, 2, handle, 3, moving knife, 4, through hole, 5, lightening hole.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.This embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Figure 1 shows that a kind of classification reinforced shear of the present invention, comprise base 1, with the hinged handle 2 in base 1 top, moving knife 3 and the stationary knife hinged with base 1 front end, the front end of described moving knife 3 and stationary knife offers respectively the U-shaped cutting edge for shear reinforcement, on described handle 2 near offering through hole 4 with hinged position, base top, the rear end of moving knife 3 is flush-mounted in through hole 4 movably, on described moving knife 3 and stationary knife, offer lightening hole 5, the front-end and back-end of described moving knife 3 connect by bearing pin, and the material of described moving knife 3 and stationary knife is 50CrV.
During work, first handle is opened to position as shown in Figure 1, then handle 2 is rotated to counter clockwise direction, the moving knife rear end being embedded in through hole 4 produces displacement, from the front end of through hole 4, move to the rear end of through hole 4, in this process, moving knife 3 rotates to an angle, and by the U-shaped cutting edge of offering on moving knife 3 and stationary knife, reinforcing bar is cut off.Adopt this set can in the situation that not changing decreased food, take lever principle as basis, change the pivot point position of handle, realize the object of gradation reinforcing, cut off rapid operation after can dividing several times reinforcing by a reinforcing bar.
Claims (6)
