Further, the front end of described steady pin is provided with the first opening, the short transverse of described first opening is parallel with the short transverse of front fixed part, described steady pin is provided with the first through hole, the second screw is provided with in described first through hole, described second screw upper driving is provided with nut, saw blade is arranged in the first opening, with the second screw, saw blade is fixed in the first opening, after tightening nut, two madial walls of the first opening are adjacent to saw blade, make saw blade have two clamping faces, when sawing, what prevent the swing of saw blade to wear and tear and cause fractures.
In order to make the rotation of the easier handsetting gear of user, further also comprise handle, described gear is rotatably installed in rectangular through-hole by rotational pin, the two ends of described rotational pin are rotatably installed on the two side of rectangular through-hole respectively, described gear is fixedly mounted on rotational pin, the rectangular through-hole sidewall of described rotational pin one end has the second through hole, and one end of described handle is fixedly connected with one end of rotational pin through the second through hole.
Further, on described steady pin, the both sides of the first opening are equipped with the second opening, and nut is plane with contacting of nut, become face contact by linear contact lay, make fixing more firm.
Further, two side planes of described tooth bar are provided with cut, add the friction of tooth bar two side plane, make tooth bar fixing more firm.
Assembling and use flow process:
Before using, the first opening is put at the two ends of saw blade, the first screw be tightened on pin, make two madial walls of the first opening be adjacent to saw blade; Rotate counterclockwise handle, gear rotates counterclockwise under the drive of handle, and gear driven tooth bar slides backward, and tooth bar slides backward and saw blade is tightened, and screws the second screw, makes the end of the second screw compress tooth bar, carries out saw pin after making tooth bar fixing.When saw blade changed by needs, by the second screw loosening, clockwise handsetting gear, makes tooth bar move forward, and saw blade loosens, and unloads more convenient, changes saw blade and is easier to.
The beneficial effects of the utility model are: the utility model uses the drive method of rack pinion to control the degree of tightness of saw blade, and structure is simple, easy to operate, avoid and use wing nut fastening, wing nut easily drops to loss, separately need join wing nut and use, increase the problem of working time and cost; Saw blade has two clamping faces, and when sawing, what prevent the swing of saw blade to wear and tear and cause fractures.
