Description

A kind of silicon rubber amendment knife

Technical field

The utility model is related to oral cavity medical apparatus, especially a kind of silicon rubber amendment knife.

Background technology

In oral medical field, silicone rubber impression is a common technology, it is necessary to silicon rubber before secondary stamp Mould is modified, to ensure the clear of secondary stamp.

It is existing be directed to mould amendment during, the general cutter hub that handle is formed with using one is installed using the handle front end Cutter head carry out the removal and amendment of unnecessary silicon rubber, but there is certain deficiency, existing knife in existing cutter hub in use Body is typically all that a handle end is provided with a cutter head, but during mould amendment, a cutter head can not be met Whole requirements of one complete makeover process, for example, remove and overflow the undercut type near ditch and abutment in bulk silicon rubber Making for silicon rubber can not all be made by a cutter head, therefore existing cutter hub needs frequent more tool changing in use Tool, use is very inconvenient.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art there is provided one kind is rational in infrastructure, meets molding requirement, It is easy to finishing, a kind of silicon rubber amendment knife simple in construction.

The utility model is adopted the technical scheme that：

A kind of silicon rubber amendment knife, including one handle, a side end of the handle, which is provided with one, to be used to overflow large area The cutter head that is cut off of silicon rubber, it is characterised in that：The end side of the handle is provided with a L-type handle of a knife, the L-type knife The upper end of handle is bent to the side of handle, and the upper end of the bending and handle are perpendicular, and the upper end of the bending is close to hand The inner side end of handle is provided with a barb type blade, the angle formed between the barb type blade and the upper end of L-type handle of a knife For 60 degree.

Advantage of the present utility model and good effect are：

In the utility model, the existing cutter head that the side end of handle one is installed is used in patternmaking process, large area is overflowed Silicon rubber cut off, L-type handle of a knife coordinates the blade of barb type, for overflowing undercut type near ditch and abutment to making Silicon rubber education amendment, cutter head and L-type handle of a knife are engaged, and meet whole requirements of existing molding, and barb type blade is arranged on L-type On the inside of handle of a knife, for improving its security for using process, prevent its in use barb type blade it is exposed to user The damage that member causes, the angle formed between barb type blade and the upper end of L-type handle of a knife is 60 degree, to reach suitable cut Chamfer degree, is easy to operating personnel to carry out cutting operation to silicon rubber.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

With reference to embodiment, the utility model is further illustrated, following embodiments are illustrative, be not limited , it is impossible to protection domain of the present utility model is limited with following embodiments.

A kind of silicon rubber amendment knife, including one handle 3, a side end of the handle, which is provided with one, to be used to overflow large area The cutter head 4 that is cut off of silicon rubber, innovation of the present utility model is that the end side of the handle is provided with a L-type Handle of a knife 1, the upper end of the L-type handle of a knife is bent to the side of handle, and the upper end of the bending and handle are perpendicular, the bending Upper end is provided with a barb type blade 2 close to the inner side end of handle, between the barb type blade and the upper end of L-type handle of a knife The angle α formed is 60 degree.

In the present embodiment, the preferable width of the barb type blade is 6mm.

In the present embodiment, fixed lid can be set with outside cutter head, by the way of cutter head and L-type handle of a knife also can be using activity installations, It is changed into demountable structure.

The course of work of the present utility model is：

The utility model is in use, operating personnel carry out large area by general cutter head to the silicon rubber mould made Amendment, to remove silicon rubber excessive in patternmaking process；Operating personnel need to only invert handle, using L-type without tool changing afterwards The barb type blade installed in handle of a knife carries out careful amendment to overflowing the undercut type silicon rubber near ditch and abutment, so as to complete The whole makeover process of mould.

Claims

1. a kind of silicon rubber amendment knife, including one handle, a side end of the handle, which is provided with one, is used for what large area was overflowed The cutter head that silicon rubber is cut off, it is characterised in that：The end side of the handle is provided with a L-type handle of a knife, the L-type handle of a knife Upper end bent to the side of handle, the upper end of the bending and handle be perpendicular, and the upper end of the bending is close to handle Inner side end one barb type blade is installed, the angle formed between the barb type blade and the upper end of L-type handle of a knife is 60 degree.
