Description
The utility model relates to a kind of saw to various metals, nonmetallic materials and adds instrument, promptly makes things convenient for coping saw.
Common coping saw, because being bent telescopic movable, the back of a bow connects, when changing saw blade, the bending of bow arm need be shortened, bring great inconvenience to the user, and need saw thicker thing sometimes and just can't use, the scope of application is subjected to bigger restriction, saw blade is difficult for fully tension in addition, and is fractureed easily.
The utility model is at above-mentioned existing problems, and its purpose is to provide a kind of mounting or dismounting more convenient and saw blade can fully be strained makes things convenient for coping saw according to bar.
The utility model is changed the structure of traditional coping saw, on handle, be provided with one rotating " L " movable rotation arm, by this pivoted arm handle and saw blade are flexibly connected, thereby can change saw blade easily, and pipe is designed to core barrel, can deposit many standby saw blades in it, but and cantilever saw blade is installed, to carry out various special saws processing.
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the structure chart of the utility model pivoted arm (4).
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model is by handle (1), the saw blade (6) that links to each other with handle (1) and pipe (7) and bow side arm formations such as (8), handle (1) is provided with one can be around " L " movable rotation arm (4) of bearing pin (5) rotation, saw blade (6) is installed on the pivoted arm (4), and saw blade (6) is regulated degree of tightness by the screw rod (3) that is connected on the handle (1)." L " movable rotation arm (4) one ends are movably connected on by bearing pin (5) that handle (1) is gone up, the other end is connected on the handle (1) by nut (2), screw rod (3).Pipe (7) is designed to hollow pipe, can deposit the multi-disc saw blade in it, and saw blade can be pulled out, and an end is fixing by screw (9).When saw blade is installed, only divide to screw screw rod (3), pivoted arm (4), pivoted arm (4) just rotates around bearing pin (5), thereby fully tension of saw blade (6).When tearing saw blade open, as long as unscrew screw rod 3, pivoted arm (4) is just loosen around bearing pin (5) rotation, and saw blade just can take out.When pull out a standby saw blade in right amount from hollow pipe, fully screw trip bolt (9), just can be to carried out special saw processing by the saw thing.
The utility model novel structure has convenient, laborsaving, the characteristics efficiently of dismounting saw blade, uses Convenience, reliable operation, being easy to make, is that a kind of saw that is suitable for adds instrument.
