Description

A kind of putty knife

(1) technical field

The utility model relates to a kind of putty knife.

(2) background technology

Putty knife is a kind of hardware commonly used, and it is made up of working blade and handle, is used for the metope processing of swiping is made the metope neat and tidy, with working blade metope is handled during use.Existing putty knife is that the afterbody with working blade all is inserted in the handle, and working blade and handle are affixed by rivet.As everyone knows, operate not only complexity but also very hard when adopting rivet that two component are coupled together, therefore existing this putty knife assembles up complicated.In addition, the afterbody of existing its working blade of putty knife is deep into the end of handle, waste material, and cost is higher.

(3) summary of the invention

For overcoming complicated, the higher deficiency of cost of putty knife assembling in the prior art, the utility model provides a kind of putty knife simple, that cost is low that assembles.

The technical scheme in the invention for solving the technical problem is: a kind of putty knife, comprise working blade and handle, the afterbody of described working blade inserts the front portion of described handle, the afterbody of described working blade offers through hole, the end of described working blade afterbody is provided with arc notch, offer on the described handle with corresponding first screwed hole of described lead to the hole site and with corresponding second screwed hole in described arc notch position, described first screwed hole, be equipped with in the through hole and first screwed hole, first screw that through hole cooperates, described second screwed hole, be equipped with in the arc notch and second screwed hole, second screw that arc notch cooperates.

The beneficial effects of the utility model are: 1. adopt screw assembling working blade and handle, assemble easy.2. the afterbody of working blade only extend into the front portion of handle, and its rear end is adopted the circular arc cutaway structure especially, has saved material, and cost is lower.

(4) description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of working blade.

Fig. 3 is the structural representation of handle.

(5) specific embodiment

The utility model is described in further detail with specific embodiment below in conjunction with accompanying drawing.

With reference to Fig. 1,2,3, a kind of putty knife, comprise working blade 1 and handle 2, the front portion that the afterbody 3 of described working blade inserts described handle 2, the afterbody 3 of described working blade offers through hole 4, the end of described working blade afterbody 3 is provided with arc notch 5, offer on the described handle 2 with corresponding first screwed hole 6 in described through hole 4 positions and with corresponding second screwed hole 7 in described arc notch 5 positions, described first screwed hole 6, be equipped with in the through hole 4 and first screwed hole, first screw 8 that through hole cooperates, described second screwed hole 7, be equipped with in the arc notch 5 and second screwed hole, second screw 9 that arc notch cooperates.Working blade 1 and handle 2 are affixed by first screw 8, second screw 9.

Because adopt screw assembling working blade 1 and handle 2, therefore assembling is very easy.3 front portions that extend into handle 2 of the afterbody of working blade, its rear end is adopted the circular arc cutaway structure especially, has saved material, and cost is lower.
