Description
Technical field
The present invention relates to cutting-tool engineering field, especially a kind of anticreep chopper being convenient to replacing handle of a knife.
Background technology
At least there are three large defects in the chopper be made up of blade and wooden handle of a knife: one is that wooden handle of a knife is easily deviate from cutter hoop; Two is that when meeting the fracture of wooden handle of a knife, the wooden handle of a knife scrapped often is difficult to take out in cutter hoop; Three be due to the axis of wooden handle of a knife and cutter hoop and blade direction inconsistent, the strength be used on wooden handle of a knife cannot be delivered on blade to greatest extent, a large amount of muscle power of waste.
Summary of the invention
The object of this invention is to provide a kind of chopper, thoroughly can solve the problem that wooden handle of a knife is deviate from, be convenient to again change handle of a knife, save a large amount of muscle power simultaneously
.
Technical scheme of the present invention is: the anticreep chopper being convenient to change handle of a knife be made up of blade and wooden handle of a knife, described blade is provided with two blocks of steel plates arranged in parallel with the knife back in the front end near the knife back, the right-hand member of described steel plate is welded on the left end end face of the first sleeve respectively, described first sleeve is provided with internal thread, the axis of the left end end face of the first sleeve is provided with manhole, and the left end of described manhole is provided with the first round boss.
The second sleeve is provided with, the external screw thread of described second sleeve and the screw-internal thread fit of the first sleeve outside the footpath of the second round boss of the left end of described wooden handle of a knife.
The axis of the left end end face of the second described sleeve is provided with screwed hole.
Be provided with hexagon socket head cap screw in described manhole and screwed hole, the bolt head of described hexagon socket head cap screw to be arranged in the first round boss and concordant with the left end end face of the first sleeve, and hexagon socket head cap screw screws in screwed hole through after manhole.
The length dimension of the second described sleeve is greater than the internal thread length dimension of the first sleeve, and the barrel that the second sleeve exposes the right-hand member of the first sleeve is provided with 2-6 small through hole, is respectively equipped with the screw hammering into wooden handle of a knife in described small through hole.
Described wooden handle of a knife, the second sleeve are consistent with the axis of the first sleeve and the blade direction of blade.
Blade is being provided with two blocks of steel plates arranged in parallel with the knife back near the front end of the knife back, be convenient to external hexagonal socket wrench and insert and to tighten between two block plates or to unscrew hexagon socket head cap screw.
Be provided with outside footpath due to the second round boss of the left end of wooden handle of a knife band externally threaded, with the second sleeve of the first sleeve screw-internal thread fit, be convenient to adopt pipe vice that the second sleeve is screwed in the first sleeve, and not easily deviate from the first sleeve, also be convenient to go out the second sleeve from the first sleeve inward turning simultaneously, easily complete the replacing of handle of a knife.
Length dimension due to the second sleeve is greater than the internal thread length dimension of the first sleeve, the barrel that second sleeve exposes the right-hand member of the first sleeve is provided with 2-6 small through hole, the screw hammering into wooden handle of a knife is respectively equipped with in small through hole, second sleeve, not affecting while the second sleeve screws in the first sleeve, can firmly be fixed on wooden handle of a knife by this structure.
Because the axis of the left end end face of the first sleeve is provided with manhole
,the left end of manhole is provided with the first round boss, the axis of the left end end face of the second sleeve is provided with screwed hole, the bolt head of hexagon socket head cap screw is arranged in the first round boss, hexagon socket head cap screw screws in screwed hole through after manhole, further the second sleeve and the first sleeve are fixed together, thoroughly solve the problem that wooden handle of a knife is deviate from.The bolt head of hexagon socket head cap screw is concordant with the left end end face of the first sleeve, can guarantee that hexagon socket head cap screw does not affect labor operation.Hexagon socket head cap screw is also convenient to adopt external hexagonal socket wrench to tighten or unscrew.
Due to wooden handle of a knife, the second sleeve and the axis of the first sleeve and the blade direction of blade consistent, the strength be used on wooden handle of a knife can be delivered on blade to greatest extent, saves a large amount of muscle power.
The right-hand member of two block plates is welded on respectively the left end end face of the first sleeve; Wooden handle of a knife is inserted the second sleeve, orders screw; Second sleeve is screwed in the first sleeve, tightens hexagon socket head cap screw, thoroughly can solve the problem that wooden handle of a knife is deviate from.When meeting the fracture of wooden handle of a knife, unscrew hexagon socket head cap screw, the second sleeve is gone out from the first sleeve inward turning, then easily can complete the replacing of wooden handle of a knife.Meanwhile, due to wooden handle of a knife, the second sleeve and the axis of the first sleeve and the blade direction of blade consistent, the strength on wooden handle of a knife can be delivered on blade to greatest extent, thus save a large amount of muscle power.
