Abstract
The utility model relates to a hacksaw bow adjustable in angle. The hacksaw bow is composed of a bow frame with an integral board type structure, a fixed ratchet wheel fixedly connected with the bow frame, a screw rod mutually connected in series with the fixed ratchet wheel, a movable ratchet wheel connected with a screw rod key, a butterfly nut connected by threads, a taper hole sleeve mutually fixedly connected with the bow frame, an elastic connector pin which ensures both ends of a saw blade to be respectively and mutually connected with the screw rod and a butterfly taper plug, and a handle which is fixedly connected with the bow frame through bolts. As long as the butterfly nut is loosened, and the butterfly taper plug is rotated clockwise, the adjustment of the included angle between the saw frame and the saw blade plane can be realized. The utility model has the characteristics of good rigidity, steady and reliable holding of the saw blade, difficult break of the saw blade and convenient angle conversion.
Description
The utility model relates to a kind of small tool, is a kind of hacksaw bow of easy hue angle.
China's Patent Gazette for Utility Models the 4th is rolled up on No. 19 and is disclosed a kind of " six use saw bow ", one of its purpose is to be used for the sawing metal, its formation is handle, saw bow, saw blade three parts, its weak point is: saw bow and handle are telescopic two bodies, poor rigidity, saw blade is easily broken; When adjusting saw frame and interplanar angle, need to take out octahedra steel bolt, after rotation, insert steel bushing again, can realize the adjustment of its angle, obviously use inconvenience.
The purpose of this utility model provides a kind of integral rigidity good for the art that overcomes above-mentioned the deficiencies in the prior art just, and saw blade is frangibility not, and can conveniently adjust the hacksaw bow of saw frame and saw blade interplanar angle.
The purpose of this utility model is to realize like this, that is: easily the hacksaw of hue angle comprises saw blade and butterfly nut, it is characterized in that the shelf that has one to have whole plank frame, affixedly decide ratchet and taper hole cover on it, regulate the moving ratchet of shelf and saw blade interplanar angle jointly, be enclosed within the butterfly tapered plug in the taper hole cover with deciding ratchet, make saw blade and screw rod and the joining resilient pin of butterfly tapered plug, and a pair is by the handle of bolt and shelf Joint.
Because shelf adopts whole plank frame, saw blade is contained in screw rod and the butterfly tapered plug groove in addition, and mutual contact-making surface increases, and the rigidity of whole system is strengthened, and can significantly reduce breaking of saw blade; Because, with key and resilient pin moving ratchet, screw rod, saw blade, butterfly tapered plug are combined as a whole, thus as long as unscrew butterfly nut, clockwise rotate the butterfly tapered plug, just can realize the adjustment of angle between saw frame and the saw blade.The size of angle is decided the corner of ratchet relatively for moving ratchet, and the number of teeth of deciding ratchet is the angle number that saw blade can be adjusted, and the end tooth number of deciding ratchet is generally the 4-12 tooth.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the utility model monnolithic case figure;
Fig. 2 is the utility model assembling schematic diagram;
Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.
Referring to Fig. 1-2 the utility model is by the shelf 1 with whole plank frame, affixed with it (weldering or riveting) decide ratchet 4, with decide the screw rod 5 that ratchet 4 is connected in series mutually, with the moving ratchet 3 of screw rod 5 usefulness key connecting and the butterfly nut 2 of thread connection, taper hole cover 8 with shelf 1 Joint (weldering or riveting), make saw blade 7 two ends respectively with screw rod 5 and butterfly tapered plug 9 joining resilient pins 6, constitute by bolt 11 handle 10 with shelf 1 Joint.One end of screw rod 5 has keyway one, and the other end has a groove and pin-and-hole, and butterfly plug screw 9 one ends have one groove and pin-and-hole.Groove on screw rod 5 and the butterfly tapered plug 9 is used for being connected saw blade with pin-and-hole and uses.Handle 10 is made of plastics, all the other each parts by metal material as: steel, iron are made.
The utility model compared with the prior art, it is good to have a whole stiffness, blade holder keeps steady surely reliable, frangibility not, indexing is convenient, good looking appearance grips the advantages such as comfortable, is suitable for sawing metal usefulness.
