Problems solved by technology

[0002] At present, when grinding a drill bit, two fingers are usually used to pinch the drill bit and grind it on the grinding wheel of the grinder, which has a great potential safety hazard. Grinding on the grinding wheel on the spiral cutting edge is very easy to cause the finger to be damaged by the spiral cutting edge on the drill bit, because there is no hand guard on the current drill bit, so the finger holding the drill bit is easily damaged by the grinding wheel, which is easy to wear to use the passive

Abstract

Provided is a machine tool drill hand-guard structure. The drill hand-guard structure comprises a lock screw, guard plates are arranged on the lock screw, a blind hole and a guard bar, a drill is arranged on the blind hole of the guard bar, the drill is fixed to the blind hole through the lock screw, and an abrasive disc is arranged on the drill. The machine tool drill hand-guard structure has the advantages that the guard plates are arranged on the guard bar provided with the lock screw and the blind hole, the drill is inserted and fastened in the blind hole of the guard bar, and therefore when a user holds the guard bar to grind the drill on the abrasive disc by fingers, the guard plates can protect the fingers, holding the guard bar, of the user, then the fingers of the user are not prone to being damaged by a spiral cutting edge and the abrasive disc of the drill, and the problems of drills in the prior art can be solved. Thus, the machine tool drill hand-guard structure has the advantages of being good in use effect, simple in structure, and easy to manufacture, implement and popularize.

Description

technical field [0001] The invention relates to a machine tool drill guard, in particular to a machine tool drill hand guard structure, which belongs to the technical field of machine tool drills. Background technique [0002] At present, when grinding a drill bit, two fingers are usually used to pinch the drill bit and grind it on the grinding wheel of the grinder, which has a great potential safety hazard. Grinding on the grinding wheel on the spiral cutting edge is very easy to cause the finger to be damaged by the spiral cutting edge on the drill bit, because there is no hand guard on the current drill bit, so the finger holding the drill bit is easily damaged by the grinding wheel, which is easy to wear To use the passive. Contents of the invention [0003] The object of the present invention is to provide a hand guard structure for a drill bit of a machine tool, which overcomes the above-mentioned defects of the existing drill bit, thereby bringing convenience in us...
