Description

The handle of a knife of putty knife

Technical field

The utility model relates to the handle of putty knife, relates in particular to a kind of handle of a knife with putty knife of outer coating layer structure.

Background technology

Putty knife is one of instrument the most frequently used in the building finishing.In the prior art, its handle of a knife is generally a solid wooden unit, and the metal handle of cutter hub is inserted in the wooden unit.In use, handle of a knife loose or dislocation very easily.In order to address the above problem, on December 19th, 2007 Chinese patent (application number: CN200620155596.3) disclose a kind of putty handle of a knife, by lower cover, the loam cake that engages with lower cover and the fuse that can insert in the lid, the corresponding symmetry of described loam cake and lower cover; The cutter drum position of described upper and lower cover front end is provided with cutter drum cover.It has overcome problems more of the prior art, but because the buffering effect of handle of a knife itself is unsatisfactory, as user during in long-time use, causes the injury of user's hand easily.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of handle of a knife of putty knife, and the handle of a knife comfortable feel of this putty knife is good.

To achieve these goals, the handle of a knife of putty knife of the present utility model, comprise loam cake, lower cover and clamping head, upper and lower cover is interlocked, and is provided with limited impression relatively in the anterior inboard of this upper and lower cover, and is provided with breach relatively at the front end bonding surface of upper and lower cover, described clamping head is contained in the described limited impression, at the slot that is axially arranged with of this clamping head upper edge handle of a knife, the front opening of this slot is corresponding with described breach, is coated with the external coating of flexible plastic at the external surface of described upper and lower cover.

After adopting technique scheme,, when the user holds handle of a knife, not only help firm gripping, and when the application of force, can obtain suitable buffering, increased comfortableness because external coating adopts the soft plastic material to make.

As the preferred embodiment of technique scheme, be respectively equipped with outwards outstanding positive stop lug boss at the upper surface of described loam cake and the soffit of lower cover, this positive stop lug boss passes described external coating, and concordant with this external coating external surface.Positive stop lug boss can avoid external coating and upper and lower cover to rotate mutually.

Preferred embodiment as technique scheme, in the anterior limited impression of described upper and lower cover, be provided with limited post relatively, on described clamping head, be provided with through hole accordingly with this limited post, when described upper and lower cover fastens, described two limited posts insert respectively in the through hole on the clamping head, and leave the gap between the termination of two limited posts.By limited post clamping head firmly is installed in the limited impression.

As another preferred embodiment of technique scheme, two head breadths of described slot, middle narrow, so that insert cutter hub.

The utility model has the advantages that: the handle of a knife of putty knife has cushioning effect, and comfortable feel is good; And the metal handle chucking of cutter hub can be made the cutter hub difficult drop-off.

Further the utility model is illustrated below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 is the structural representation of the utility model embodiment;

Fig. 3 is the sectional view along A-A line among Fig. 1;

Fig. 4 is the zoomed-in view at I place among Fig. 3.

The specific embodiment

Referring to Fig. 1 to Fig. 4, the handle of a knife of putty knife is made of loam cake 1, lower cover 2, clamping head 3 and external coating 4, and upper and

lower cover

1,2 is a hollow arc lid, and shape is symmetry substantially.Be provided with alignment pin on the bonding surface of loam cake 1, the corresponding locating hole that is provided with on the bonding surface of lower cover 2 closely fastens upper and

lower cover

1,2 by alignment pin and locating hole.Anterior inboard at this upper and

lower cover

1,2 is provided with limited impression relatively, is provided with limited post 8 in this limited impression relatively, and is provided with breach 5 relatively at the front end bonding surface of upper and

lower cover

1,2.

Referring to Fig. 2,3 and Fig. 4, the shape of clamping head 3 and size cooperate with limited impression, clamping head 3 upper edge handle of a knifes be axially arranged with slot 3a, two head breadths of this slot 3a, the centre is narrow.On this clamping head 3, be provided with the through hole that inserts for described limited post 8.When upper and

lower cover

1,2 fastened, two limited posts 8 inserted respectively in the through hole on the clamping head 3, and leave the gap between the termination of two limited posts 8.Slot 3a on the clamping head 3 is corresponding with the breach 5 on the upper and

lower cover

1,2, can insert the slot 3a from breach 5 with the metal handle 9a that guarantees cutter hub 9.Because of the thickness of slot 3a is suitable with metal handle 9a, and the width in the middle of the slot 3a is slightly less than the width of metal handle 9a, and therefore, metal handle 9a is made the cutter hub difficult drop-off by among the firm slot 3a that is stuck in clamping head 3.

External surface at upper and

lower cover

1,2 is coated with external coating 4, and the polyvinyl chloride of external coating 4 usefulness environment-protecting asepsis is the material injection mo(u)lding, and polyvinyl chloride is a flexible plastic, to increase the comfortableness of feel.Be respectively equipped with outwards outstanding positive stop lug boss 6 at the upper surface of loam cake 1 and the soffit of lower cover 2, this positive stop lug boss 6 passes external coating 4, and concordant with these external coating 4 external surfaces, makes external coating 4 difficult drop-offs.
