Abstract
The utility model discloses a kind of dental drill drill handle of a knife, including handle of a knife body, described handle of a knife body is column structure, described handle of a knife bodies top is provided with that to set fluted, described handle of a knife body that semicylinder junction is provided with arc with the semicylinder of handle of a knife body integrative-structure and described semicylinder medium position domatic.Generally, the utility model has the advantages that design structure is reasonable, and manufacturing cost is low, and production efficiency is high.
Description
Technical field
It the utility model is related to a kind of dental drill drill, and in particular to a kind of dental drill drill handle of a knife.
Background technology
At present, common dental drill drill（Drill bit）Usually handle of a knife and drill are formed in one the drill of structure, due to whole
Its production cost is larger for wolfram steel for body material, is not easy to save cost.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and reasonable, the manufacturing cost that provides a kind of design structure
It is low, a kind of high dental drill drill handle of a knife of production efficiency.
In order to realize the purpose of this utility model, what the technical solution of the utility model was realized in：A kind of tooth
Bore drill handle of a knife, including handle of a knife body, described handle of a knife body be column structure, described handle of a knife bodies top be provided with and
The semicylinder of handle of a knife body integrative-structure and described semicylinder medium position set fluted, described handle of a knife body with
It is domatic that semicylinder junction is provided with arc.
The tapered structure of hypomere in described handle of a knife body.
Beneficial effect is caused by the utility model：The utility model is to separate drill drill bit and handle of a knife, by this
The handle of a knife that utility model is related to is designed, and the handle of a knife after manufacture is welded in into one, knife by drill bit again by welding manner
Handle is stainless iron material, and the cost of manufacture is greatlyd save compared with wolfram steel.By the design of the utility model handle of a knife, in handle of a knife
The top of body sets a semicylinder being structure as a whole with handle of a knife, and a groove, and semicolumn are set on semicylinder
The link position of body and handle of a knife body is provided with that arc is domatic, improves the intensity of handle of a knife body on the whole, semicylinder is set
Meter can be such that handle of a knife is firmly fixed on tooth machine, and hypomere in handle of a knife body is designed as boring by second of handle of a knife body design
Shape structure, it can be more convenient when welding drill head.
Generally, the utility model has the advantages that design structure is reasonable, and manufacturing cost is low, and production efficiency is high.
