Abstract
The invention discloses a ratchet type reinforcing steel bar cutter comprising a base, a tool rest fixed to the base and a blade hinged to the tool rest. A ratchet gear is connected to the base in a rotatable mode. The blade is connected with a handle. The front end of the handle is in the shape of ratchet teeth, the ratchet teeth are meshed with the ratchet gear connected to the base. The lower portion of the handle is connected with an L-shaped shifting block. The other end of the L-shaped shifting block is tightly attached to the back of the blade. The rear end of the handle is in the shape which enables people to hold the handle by hand. The cutting edge portion of the blade is zigzag. A through hole and a groove which are used for reducing the weight are formed in the tool rest. Due to the fact that the ratchet structure is applied to the ratchet type reinforcing steel bar cutter, large shearing force can be obtained just through small human power, a good reinforcing steel bar shearing effect can be achieved, and production efficiency is high.
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 ratchet-type 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 ratchet-type reinforced shear, comprise base, be fixed on the knife rest on base, and the blade hinged with knife rest, a ratchet gear has been rotatably connected on base, described blade is connected with a handle, the front end of described handle is set to ratchet profile of tooth, with the ratchet gear engagement being connected on described base, the bottom of handle front end is connected with a L shaped shifting block, the other end of L shaped shifting block is close to the back of described blade, and the rear end of handle is set to the shape that can grip for staff.
As a kind of optimal way, the blade of described blade is set to zigzag.
As a kind of further optimization, on described knife rest, offer for alleviating through hole and the groove of quality.
As a kind of further optimization, on described handle, be provided with the spin-block for fixed handle position, on described base, be provided for placing the curved surface of spin-block.
The invention has the beneficial effects as follows: in reinforced shear, adopt ratchet structure, only need just can provide larger shearing force with less manpower, can obtain good bar cutting effect, production efficiency is high; On knife rest, be provided with for alleviating the through hole of quality, make the oeverall quality of reinforced shear little, be convenient to transportation; On handle, be provided with the spin-block for fixed handle position, make reinforced shear can not produce accident when not working, improved security.
Accompanying drawing explanation
Fig. 1 is the structural representation that reinforced shear of the present invention comprises base portion;
Fig. 2 is the structural representation that reinforced shear of the present invention does not comprise base portion;
In figure: 1, base, 2, knife rest, 3, blade, 4, ratchet gear, 5, handle, 6, L shaped shifting block, 7, spin-block, 8, groove, 9, through hole.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
Fig. 1 and Fig. 2 are in conjunction with being depicted as a kind of ratchet-type reinforced shear of the present invention, comprise base 1, be fixed on the knife rest 2 on base 1, and the blade 3 hinged with knife rest 2, the ratchet gear 4 that has been rotatably connected on base 1, offers on knife rest 2 for alleviating groove 8 and the through hole 9 of quality.The blade of described blade 3 is set to zigzag, blade 3 is connected with a handle 5, the front end of described handle 5 is set to ratchet profile of tooth, with ratchet gear 4 engagements that are connected on described base 1, the bottom of handle 5 front ends is connected with a L shaped shifting block 6, and the other end of L shaped shifting block 6 is close to the back of described blade 3, and the rear end of handle 5 is set to the shape that can grip for staff, on handle 5, be provided with the spin-block 7 for fixed position, on described base 1, be provided for placing the curved surface of spin-block 7.
As shown in Figure 1, during use, by the grip part of fixed handle 5 rear ends to turning clockwise, ratchet gear 4 rotates to counter clockwise direction by the handle 5 front end hook tooths of engagement, the L shaped shifting block 6 of handle 5 front end bottoms, for the power that blade 3 provides counter clockwise direction to rotate, can be cut off the reinforcing bar being placed in knife rest 2 and blade 3, only need just can provide larger shearing force with less manpower, can obtain good bar cutting effect, production efficiency is high; On knife rest 2, be provided with for alleviating groove 8 and the through hole 9 of quality, make the oeverall quality of reinforced shear little, be convenient to transportation.When not using, the spin-block on handle 57 can be placed on the curved surface arranging on base 1, handle 5 cannot, again to rotating clockwise or counterclockwise, guarantee the safety that reinforced shear is used.
