Description

Putty knife

Technical field:

The utility model is a kind of putty knife, relates to the manual tool technical field, relates in particular to builing industry manual tool technical field.

Technical background:

Now it is made up of sheet cutter (1), hilt (2) and lock ring (3) Chang Yong putty knife as shown in Figure 1, and wherein the cutter tail (11) of cutter inserts hilt (2), and lock ring (3) is arranged at the front end of hilt (2), and by it cutter (1) and hilt (2) lock ring is integral.This putty knife through the decoration of the wall decoration of the building of being everlasting, window glass, add and adopt man-hour, be widely used owing to it is simple in structure, inexpensive, simple for production, the main disadvantage of this kind putty knife is that wooden handgrip intensity is low, the tightening force of poor flexibility, lock ring is very limited, so stressed back cutter and hilt are easy to break away from, application life is short, and is uneconomical, especially needs broad and stressed greatly the time when the cutter head position, the disadvantage that breaks away from is just more outstanding, therefore must be improved.

Summary of the invention:

The object of the present invention is to provide a kind of simple in structure, easy to make, cutter and hilt can disengaging, the putty knife of long service life, good economical benefit.

The purpose of this utility model is to realize like this, a kind of putty knife, include sheet cutter (1), hilt (2), wherein the cutter tail (11) of cutter is located at the centre of hilt (2), cutter tail (11) portion that it is characterized in that cutter is provided with double wedge (111), or recessed tooth (112), or crotch (113) or hole (114), or be pre-small post-large taper (115), hilt (2) is one to have the plastics handle of strong intensity, and its centre is provided with and cutter tail (11) and double wedge (111) thereof, or recessed tooth (112), or crotch (113) or hole (114), or the groove (211) of taper (115) phase assembly, or groove (212), or groove (213), or groove (214), or groove (215) and cutter are integral (2) injection moulding by its cutter tail (11) portion and plastic knife.

Advantage of the present utility model is: simple in structure, easy to make, and be subjected to force intensity big, long service life, good economical benefit, use value height.

The specific embodiment:

Embodiment 1

By Fig. 2 a, 2b, Fig. 3 a, shown in the 3b as seen, its cutter head portion (12) of the putty knife of present embodiment 1 is for being wide flat-shaped, and by the curved curve transition in both sides (13) to afterbody (11), afterbody (11) is the herring bone shape, be provided with double wedge (111) in the both sides of afterbody (11), the corresponding section, centre of hilt (2) is provided with the groove (211) of joining with afterbody and double wedge, and the teeth groove structure of phase assembly thus and afterbody (11) and plastic knife handle (2) injection moulding all-in-one-piece structure, make cutter and hilt not only overcome the disadvantage of easy disengaging, and make it increased greatly by force intensity, thereby make putty knife long service life of the present utility model, the intensity height, effective, the scope of application is wide, has been widely used in building wall and has decorated, glass decoration and making, in the operations such as furniture decoration and flowers cultivation.When the width of the head (12) of its cutter is 8-12 centimetre particularly 9-11 centimetre the time, it not only can have the fine force intensity that is subjected to, and the increase of Job Operations face, thereby can in making such as hollow glass, increase work efficiency greatly and application life, thus make it have good economic benefits.

Embodiment

2,3

Only be that by the difference of visible it and embodiment 1 shown in Fig. 4 a, 4b, Fig. 5 a, 5b, the 5c double wedge (111) of cutter afterbody (11) and the groove (211) of hilt (2) change into recessed tooth (112) and groove (212) or crotch (113) and groove (213), its act on and benefit all with

Embodiment 1 is suitable.

Embodiment 4

By shown in Fig. 6 a, the 6b as seen, because cutter afterbody (11) is provided with at least one perforate (114) at itself and plastic knife handle (2) when injection moulding is integral, its hole (114) locates just have plastics to be pressed into, and overcomes cutter and the easy disadvantage that breaks away from of hilt and increases application life thereby also can reach.

By Fig. 7 a, 7b as seen, the cutter afterbody (11) of cutter (1) is designed to pre-small post-large taper (115), hilt (2) is gone up the corresponding for this reason cone tank (215) of corresponding groove (215) design, and both same injection mouldings are integral with this, it can realize the object of the invention too.

In addition by shown in Fig. 2 b as seen, for the ease of putty knife is preserved, can on its hilt (2), be provided with one and hang the hanging hole (22) that putty knife is used; For the ease of use, operation, can be made in handgrip (2) and upper and lowerly be the curved flat circular arc body in plane, both sides, and can be provided with the concave surface (21) that can place finger at the front end place of handgrip (2).
