Abstract

The invention discloses a wood drill with a check ring. The wood drill with the check ring is simple in structure, safe in use and high in drilling efficiency. The wood drill comprises a drill body; the front end of the drill body is a cutting edge, the drill body is provided with a spiral dust discharge groove, and the tail end of the drill body is provided with a drill shank used for being clamped. The wood drill is characterized in that the circular check ring is installed at the front end of the drill shank. When the wood drill with the check ring is used, wood dust which is upwards discharged from the dust discharge groove is stopped by the check ring, and the splashed wood dust falls off beside drilled holes; besides, in the drilling process, the depth of the drilled holes can be conveniently controlled by allowing the front end of the check ring to abut against wood on the surfaces of hole openings, and therefore the drilled holes can be uniform in depth.

Description

Carpenter's auger with back-up ring

Technical field

The invention belongs to wood working tool, particularly the boring carpenter's auger with back-up ring of carpenter.

Background technology

Because carpenter's auger is than drilling metal is large by the brill cutting output of fluted drill, feed speed is fast, solid capacity is many, particularly for the hard timber of drilling material, discharge wood chip can scatter and splash, easily enter in operator's eyes or near tooling device, cause the infringement to the injury of human body or tooling device.

Summary of the invention

The object of this invention is to provide a kind of simple in structure, use safety, the carpenter's auger with back-up ring that drilling efficiency is high.

In order to reach above-mentioned requirements, the present invention is achieved by the following technical solutions: it includes brill body, and the front end that bores body is cutting edge, bores and be shaped with spiral chip area with it, at the tail end that bores body, be shaped with the drillstock for clamping, it is characterized in that, at the front end of drillstock, circular back-up ring is installed.

Described back-up ring has circular groove for middle, is shaped with the through hole matching with drillstock in groove.

According to the carpenter's auger with back-up ring of such scheme manufacture, in use, the wood chip of upwards discharging from chip area is stopped by back-up ring, the wood chip sputtering drops on holed side, and when drilling, can utilize the front end of back-up ring to touch the degree of depth that facilitates keyhole at the timber of vent surface, make boring in the unified degree of depth.

Accompanying drawing explanation

Fig. 1 is the front view with the carpenter's auger of back-up ring;

Fig. 2 be carpenter's auger with back-up ring before back-up ring after shimming, state diagram during boring.

In figure: 1, bore body; 2, cutting edge; 3, chip area; 4, drillstock; 5, back-up ring; 6, groove; 7, through hole; 8, pad.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Fig. 1 is the structural representation with the carpenter's auger of back-up ring.As seen from the figure, it includes bores body 1, the front end that bores body 1 is cutting edge 2, bore on body 1 and be shaped with spiral chip area 3, at the tail end that bores body 1, be shaped with the drillstock 4 for clamping, front end sleeve at drillstock 4 has circular back-up ring 5, and described back-up ring 5 has circular groove 6 for middle, is shaped with the through hole 7 matching with drillstock 4 in groove 6.In use, drill chuck is clamped drillstock 4, utilizes back-up ring 6 front ends to the feature of cutting edge 2 fixed length, and can utilize length that pad 8 adjusts L as shown in Figure 2, reaches the object that facilitates the keyhole degree of depth.

Claims

1. with the carpenter's auger of back-up ring, it includes brill body, and the front end that bores body is cutting edge, bores and is shaped with spiral chip area with it, at the tail end that bores body, is shaped with the drillstock for clamping, it is characterized in that, at the front end of drillstock, circular back-up ring is installed.

2. according to the carpenter's auger with back-up ring described in claim l, it is characterized in that described back-up ring has circular groove for middle, is shaped with the through hole matching with drillstock in groove.
