Abstract
The utility model discloses a reinforcing bar shears, including the casing, with this casing one end fixed connection's knife rest, with the movable carriage of this knife rest cooperation use to reach the balance handle with this casing other end fixed connection, its characteristics are: be equipped with ratchet gear and reduction gear system in the casing, ratchet gear and reduction gear system nibble the merga pass gear shaft and install in the casing, and ratchet gear is connected with and leads to the outer handle of casing still is equipped with the locating pin in the casing, it is articulated that knife rest and movable carriage pass through the swivel pin, is equipped with the cutting edge on the knife rest, and movable carriage one end is equipped with the cutting edge, and the movable carriage other end is equipped with the teeth of a cogwheel, and movable carriage's wheel increment passes through the effect and reduction gear system meshing of locating pin, and the outer one side of casing is equipped with ratchet gear's positive and negative spanner. The utility model discloses a ratchet gear and reduction gear system structure, it just can provide very big shearing force with less manpower only to need, can obtain fine reinforcing bar shears and cut the effect, can cut thicker reinforcing bar, the application scope guangZhou.
Description
Technical field
The utility model belongs to building implement technical field, especially relates to a kind of reinforced shear.
Background technology
Reinforced shear of the prior art is generally made up of cutter hub and handle, operation is painstaking, therefore many technical staff have made some improvements reinforced shear, such as patent application number is a kind of ratchet-type reinforced shear of 2013107029631, but this shearing force increased by single ratcheting manner is very limited, still very painstaking when running into the reinforcing bar of a little thick point, be therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of reinforced shear, and it has only needs less manpower just can obtain good shear effect, the feature of long service life.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of reinforced shear, comprises housing, the knife rest be fixedly connected with this shell one end, with this knife rest with the use of movable carriage, and the balance handle be fixedly connected with this housing other end, be characterized in: in described housing, be provided with ratchet gear and train of reduction gears, described ratchet gear and train of reduction gears are nibbled merga pass gear shaft and are arranged in housing, described ratchet gear is connected with towards the handle outside described housing, also alignment pin is provided with in described housing, described knife rest and movable carriage are movably hinged by swivel pin, described knife rest is provided with blade, described movable carriage one end is provided with blade, the described movable carriage other end is provided with the gear teeth, the gear teeth end of described movable carriage is engaged with train of reduction gears by the effect of described alignment pin, the outer side of described housing is provided with the positive and negative spanner of ratchet gear.
Above-mentioned a kind of reinforced shear, wherein, described housing two side bottom is provided with balance wing.
After adopting said structure, the utility model is compared to the prior art advantageously: the ratchet gear that the utility model adopts and train of reduction gears structure, only need with less manpower, just can provide very large shearing force, good bar cutting effect can be obtained, thicker reinforcing bar can be sheared, applied widely.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model does not comprise housing parts.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the utility model birds-eye perspective.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, see shown in Fig. 1 to Fig. 3:
Ratchet gear and train of reduction gears widely use at present, its structure and principle same as the prior art, repeat no more here.
A kind of reinforced shear, comprises housing 12, the knife rest 5 be fixedly connected with this housing 12 one end, with this knife rest 5 with the use of movable carriage 3, and the balance handle 11 be fixedly connected with this housing 12 other end.Ratchet gear 2 and train of reduction gears 9 is provided with in housing 12, ratchet gear 2 and train of reduction gears 9 are nibbled merga pass gear shaft 8 and are arranged in housing, ratchet gear 2 is connected with towards the handle 1 outside housing 12, alignment pin 6 is also provided with in housing 1, alignment pin 6 there is the groove provided constraints, knife rest 5 and movable carriage 3 are movably hinged by swivel pin 4, knife rest 5 is provided with blade (accompanying drawing does not draw), movable carriage 3 one end is provided with blade (accompanying drawing does not draw), movable carriage 3 other end is provided with the gear teeth 7, the gear teeth end of movable carriage 3 is engaged with train of reduction gears 9 by the effect of alignment pin 6, the outer side of housing 12 is provided with the positive and negative spanner 10 of ratchet gear 2, positive and negative spanner 10 controls feed or withdrawing, preferably, housing 12 liang of side bottoms arrange the balance wing 13 that can increase counterbalance effect.
During operation, reinforced shear is put in ground, balance handle 11 and balance wing 13 are developed with ground, as long as repeat to press handle 1 several times, just can reach the object of bar cutting, required manpower is far smaller than the shearing force needed for bar cutting.
Claims (2)
