Abstract
The utility model relates to a connecting rod of a hole saw, in particular to a connecting rod of a carbon steel hole saw used for woodworking, which comprises a main body, a center drill is inserted in the main body, the hole saw is sleeved in the main body, and the hole saw is fixed with the center drill. The connecting rod of the hole saw has the advantages of simple structure, convenient disassembly and assembly, strong stability, good concentricity and prolonged service life.
Description
Technical field
The utility model is a kind of hole saw extension bar, and particularly a kind of carpenter uses the carbon steel hole saw extension bar of hole saw.
Background technology
Hole saw extension bar in the prior art, dismounting inconvenience, and assembling relative complex, operate not easy, and intensity height own, location difficulty.
Chinese patent CN200920046928.8, a kind of improved hole saw connecting rod is disclosed, hole saw is a kind of specific purpose tool of punching, between existing hole saw head and the connecting rod is that the employing center is threaded, the pin location, but its deficiency is that when pin inserts locating hole the center is threaded, and part is very difficult tightens fully.This utility model structure relative complex, and dismounting inconvenience.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of carpenter's of being used for carbon steel hole saw extension bar is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of carbon steel hole saw extension bar comprises main body, is plugged with centre drill in the main body, is with hole saw in the described main body, and described hole saw and centre drill fix.Be fit to the carpenter and use the carbon steel hole saw, adopt the quality carbon steel manufacturing, the bulk heat treatmet sclerosis, the centering of carbon-bearing steel center bit, good concentricity, easy for operation, dependable performance.
As preferably, described hole saw and main body are fastened by hexagonal nuts, and described centre drill and main body are by screw apical grafting mutually, and described centre drill is located at the centre bit in the hole saw.Hole saw is quick and easy for installation, simultaneously the tightness height.
As preferably, the afterbody of described centre drill is a shank, and described shank is the triangle clamping bar.The triangle clamping bar is fit to the carpenter and uses the tightness height.
As preferably, described main body and centre drill are respectively carbon-steel parts.
Therefore, the carbon steel hole saw extension bar that the utility model provides, simple in structure, easy accessibility, stability is strong, and good concentricity increases the service life.
