Description

A kind of integral type putty knife

Technical field

The utility model is related to building, the paint auxiliary material instrument of decorative craft, particularly a kind of integral type putty knife.

Background technology

Putty knife is also referred to as scraper, is the commonly used hand-held tool of painter of building, decorative craft, its structure is typically by handle Constitute with the blade being fixed on handle, carry out scraping, the behaviour such as apply, fill out using the bottom surface layer that above can easily treat paint Make.

A kind of putty knife disclosed in Chinese Patent No. 200520118175.9, structure includes sheet knife, hilt, in knife Afterbody be provided with double wedge or concave tooth or crotch or hole or tapered, sheet knife located at the centre of hilt, and in hilt Corresponding position is provided with the groove that double wedge with knife or concave tooth or crotch or taper phase assemble, and knife has higher-strength by its afterbody with this Plastics handle hot pressing cast solid.But the tautness between the handle of this structure and blade is also undesirable, using a timing Between after blade easily occur loosen or situation about getting loose, in addition, its construction class is not high.

A kind of putty knife increasing putty knife shank intensity, structure disclosed in Chinese Patent No. 201220733458.4 It is made up of putty knife cutter head and putty knife handle of a knife it is characterised in that described putty knife handle of a knife is by carrying reeded handle of a knife epivalve and band Reeded handle of a knife hypovalve is constituted, and described handle of a knife epivalve is in that band groove surface is fixedly connected composition putty knife relative to shape with handle of a knife hypovalve Handle of a knife is overall；The afterbody of described putty knife cutter head is located in the groove of putty knife handle of a knife, and solid according to connector with putty knife handle of a knife Fixed connection.But the tautness between the handle of this structure and blade is also undesirable, using knife also easily occurred after certain time The situation that piece loosens, its construction class is not also high.

Content of the invention

In order to overcome existing putty knife to deposit after a certain period of use time, the situation that blade loosens or gets loose easily occurs, and its The not high defect of construction class, the purpose of this utility model is to provide a kind of improved integral type putty knife, can overcome existing The defect of technology.

The utility model solves its technical problem and be employed technical scheme comprise that：A kind of integral type putty knife, including handle Blade with being fixed on handle, is characterized in that：The handle core with some lug, nibs and note that described handle is molded by metal casting Make outside handle core plastic shaped body constitute and be by described lug, nib outside end face common with described plastic shaping external surface Constitute the outer surface of described handle, described handle core front end is fixedly connected by welding with blade rear end and welding position is Make to be formed integraty appearance between described handle core and blade through rubbing down.

Outside the handle that outside lug, nib described in technique scheme, end face is collectively formed with described plastic shaping external surface Surface, can be the smooth surface being formed through rubbing down.

Described handle core front end described in technique scheme and blade rear end can be provided with laterally projecting position, in handle core front end With after blade rear end welding, described laterally projecting position is cut away, so can ensure that the smooth of described welding position side Property.

End face outside described lug, nib described in technique scheme, can be portion end surface outside lug, nib or prominent Whole end faces outside rib.

The beneficial effects of the utility model：The handle core with some lug, nibs that is molded by metal casting due to described handle and The plastic shaped body that note is made outside handle core is constituted, and is by end face outside described lug, nib with described plastic shaping external surface altogether With the outer surface constituting described handle, described handle core front end and blade rear end are fixedly connected by welding and welding position It is to make to form integraty appearance between described handle core and blade through rubbing down, so the tautness between handle and blade is very Good, be not in the situation that blade loosens or gets loose；And the metal end outside described lug, nib shows out in described plastic shaped body Between outer surface, constitute the especially decorative aesthetics of novelty, its product specification can significantly improve.

Below in conjunction with drawings and Examples, the utility model is described in further detail.
