Abstract
The utility model relates to a hole saw, in particular to an adjustable hole saw with a double-blade which is used to process wood and comprises a scale bar. The scale bar is provided with a main body. The bottom of the main body is provided with a center drill. Two ends of the scale bar are respectively provided with movable blade assemblies. The adjustable hole saw with the double-blade has the advantages of being compact in structure, adjustable and flexible in operation.
Description
Technical field
The utility model is a kind of hole saw, and the adjustable hole saw of particularly a kind of double-pole is used for wood processing.
Background technology
The function of hole saw of the prior art all is very single, and exists performance accuracy low, simultaneously incomparable exact position.
Chinese patent 200720175596.4 discloses a kind of alloy hole saw.Comprise location drill bit, circular cutter hub, welding-on a plurality of cutting edges, the clamp shaft at circular cutter hub openend, the cross section of said clamp shaft is a triangle, and said clamp shaft and said circular cutter hub are to be formed through cold extrusion by same metal material; Said location drill bit is inlaid in said circular cutter hub center and is fixed by screw.This structure function is single, does not have adjustability.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, and is simple in structure, and the adjustable hole saw of double-pole with adjustability.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The adjustable hole saw of a kind of double-pole comprises the chi bar, is provided with main body in the described chi bar, and the bottom of described main body is provided with centre drill, and the two ends of described chi bar are respectively equipped with movably blade assembly.
The blade assembly is used for regulating, locating and cut saw, and easy to operate, simultaneously easy to operate, flexibility is high.
As preferably, described main body is positioned at the centre bit of chi bar, is respectively equipped with yardstick on the chi bar at described main body two ends; Described blade assembly comprises tool rest and blade; Described tool rest and chi bar socket-connect, and described blade is located at the lateral wall of tool rest, and the bottom of described blade is outward-dipping.
As preferably, the top of described main body is inserted link, is with packing ring in the described inserted link, and the two side ends of described chi bar is respectively equipped with shrouding.
Therefore, the adjustable hole saw of a kind of double-pole that the utility model provides, compact conformation has adjustability, flexible operation.
