The putty knife comprises the handle, the inserted joint part and the cutter body; after the structures of the three parts are molded separately, the cutter body is mounted on the handle through the inserted joint part; and the manufacturing of the product is completed. The novel putty knife has the advantages of convenient mounting, high production efficiency, reasonable structure and reliable application.
Description
Technical field
The utility model relates to the building finishing instrument, particularly a kind of novel putty knife.
Background technology
Present putty knife generally is made up of handle and the cutter hub two parts that are installed in the handle front end, when making, earlier cutter hub is positioned in the mould, thereby the plastic cement that reinjects forms the putty knife handle, this manufacture craft needs cutter hub is placed in the mould accurately in production engineering, and production efficiency is low relatively, and its materials that inject plastic cement are more, under the situation that resource worsening shortages, the prices of raw and semifnished materials rise steadily, can not satisfy social demand efficient, that economize on resources.
Summary of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of rational in infrastructure, novel putty knife of service-strong.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of novel putty knife comprises handle, plug connector and cutter hub, and the front end of handle has draw-in groove, and the back link of cutter hub is pegged graft by plug connector and is clamped in the draw-in groove.
Further, described handle has the hollow cavity that connects the front and back end, and described draw-in groove is positioned at the front end of this hollow cavity, the hollow cavity rear end of handle is provided with the tail plug, because handle inside is hollow cavity, thereby can save material, cost of production can effectively reduce.
The beneficial effects of the utility model are: because this putty knife is made up of handle, plug connector and cutter hub three parts, after the structure difference moulding of three parts, cutter hub is installed in the manufacturing that can finish product on the handle by plug connector, it is easy for installation, production efficiency is high, and rational in infrastructure, use reliable.

The specific embodiment
With reference to Fig. 1～Fig. 8, a kind of novel putty knife of the present utility model comprises handle 1, plug connector 2 and cutter hub 3, and the front end of handle 1 has draw-in groove 10, and the back link of cutter hub 3 is pegged graft by plug connector 2 and is clamped in the draw-in groove 10.
Further, described plug connector 2 comprises left fixture block 20 and right fixture block 22, between the back link of left and right fixture block 20,22 and cutter hub 3 positioner is arranged, and between the draw-in groove 10 of left and right fixture block 20,22 and handle 1 tightening device is arranged.
Wherein, as preferred implementation, positioner between the back link of left and right fixture block 20,22 and cutter hub 3 comprises the hole clipping 30 on the back link that is arranged on the reference column 24 between the left and right fixture block 20,22 and is arranged on cutter hub 3, left and right fixture block 20,22 is plugged in the draw-in groove 10, and the back link of cutter hub 3 is clamped between the left and right fixture block 20,22.
In addition, as preferred implementation, tightening device between the draw-in groove 10 of left and right fixture block 20,22 and handle 1 comprises the card platform 12 on the draw-in groove 10 rear end sidewalls and the protruding fixture block 26 of left and right fixture block 20,22 rear ends, after the left and right fixture block 20,22 of link is pegged graft and is entered draw-in groove 10 behind the clamping cutter hub, be held on the card platform 12 by protruding fixture block 26, thereby cutter hub 3 is fixed on the handle 1.
Further, fuse by connecting band 28 between the afterbody of described left fixture block 20 and right fixture block 22, make it to be convenient in process of production assembling.
In addition, as preferred implementation, described handle 1 has the hollow cavity that connects the front and back end, and described draw-in groove 10 is positioned at the front end of this hollow cavity, and the hollow cavity rear end of handle 1 is provided with tail plug 4, can save raw material, cost of production effectively can be reduced.
In addition, as shown in Figure 7, another embodiment of the present utility model, described handle 1 has the hollow cavity that connects the front and back end, and described draw-in groove 10 is positioned at the front end of this hollow cavity, and the hollow cavity rear end of handle 1 is provided with tail plug 4, the front end of described tail plug 4 is provided with one and struts post 40, the rear end that struts post 40 reaches to the inboard of the protruding fixture block 26 of left and right fixture block 20,22 rear ends, prevents that protruding fixture block 26 from moving inward disengaging card platform 12, makes mounting structure firmly, reliably.
After each component-assembled of the present utility model, promptly as shown in Figure 8, cutter hub 3 is by plug connector 2 fastening being fixed on the handle 1, and it is connected firmly, uses reliable, and cost of manufacture is cheap, production efficiency is high.
Certainly, the invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
