Description

Hand saw capable of light guiding orientation cutting
Technical field
The present invention relates to handsaw, particularly a kind of hand saw capable of light guiding orientation cutting that when the sawing material, uses.
Background technology
This hand tools of handsaw is generally used during the sawing material in repair of machine, assembling.Traditional handsaw exists not enough, one handsaw wherein an end one screw and nut are arranged, play and strain and unclamp the saw blade effect, when promptly not sharp or fracture need to be changed when saw blade, need unscrew nut, saw blade is got from handsaw, load onto new saw blade then, again with nut screwing clamping; Thereby when changing saw blade, a pine one is tight, and promptly trouble is time-consuming again, and uses the nut profile less, and frequent operation easily causes operator's fatigue; It two is when need are adjusted the sawing angle, must pull down nut, can adjust, and its angle has 0 degree and 90 and spends both directions; It three is in the dark weak local operation of light, sawing position location difficulty.The applying date is that " a kind of saw frame " (notification number is CN2508920 Y) of the Chinese utility model patent ZL01271894.7 in December 05 calendar year 2001 seen accompanying drawing 3 with regard to the saw frame that belongs to this class formation; The front end of this saw frame 2 has a blind rivet 9, the other end has a circular seat 11, in the seat hole 12 is arranged, the front end of rolling cover 3 is connected with hole 12 by two protruded stigmas, be provided with fulcrum 6 in rolling cover 3, support brace 7 is provided with open slot, and open slot is enclosed within on the fulcrum 6, and be welded with nut 5 in the upper end of groove, be provided with adjustment screw 4 in nut 5, the front end of support brace 7 passes the breach of rolling cover 3 bottoms and stretches in the outside of saw frame 2, is provided with blind rivet 10 at its extension and forms, when changing or during the new clothes saw blade, only need to adjust adjustment screw 4, rolling cover 3 toward drop-down, is fixed on saw blade-holder on blind rivet 9 and 10 according to length of saw blade, then rolling cover 3 is upwards closed, can use.It is simple in structure, and make things convenient for during use, save time, though the problems referred to above one are made certain improvements, but still bother time-consuming; Especially this handsaw still fails to solve the above problems two, three, can't finish the conversion of sawing angle random, also can't finish at the dark weak place of light accurately orientation cutting on material, has influenced the function of handsaw.
Summary of the invention
Technical problem to be solved by this invention is time-consuming at above-mentioned trouble when changing saw blade, the nut profile is little, sawing angle adjustment scope is little, defectives such as sawing position location is inaccurate, and provide can convenient and swift replacing saw blade, the accurate hand saw capable of light guiding orientation cutting of orientation cutting position, conversion sawing angle.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
