Description

A kind of novel scraper

Technical field

The utility model relates to a kind of scraper, is specifically related to a kind of novel scraper.

Background technology

Scraper, also known as trowel, is repair the instrument the widest at most that uses in type, there are tack, tip and round end etc. several, the bigger plane being mainly used to repair molding sand (core), excavation waters rising head, cutting groove and casting rib, finishing sand base and soft or hard casting bed, the strengthening nail of mould surface is lifted into sand mold etc., and scraper is the main tool of scraping, owing to the shape of workpiece is different, therefore it is required that scraper has different shapes, generally it is divided into plane scraper and curved surface scraper two class. Traditional blade construction more complicated, processing and manufacturing is inconvenient, adds manufacturing cost, be therefore badly in need of a kind of structure simple, be convenient to processing and manufacturing, simultaneously easy to use, the novel scraper that practicality is high.

Practical novel content

The utility model is for the problems referred to above, it is provided that a kind of structure is simple, be convenient to processing and manufacturing, simultaneously easy to use, the novel scraper that practicality is high.

The technical scheme in the invention for solving the above technical problem is:

A kind of novel scraper, wherein, comprise handle of a knife and be arranged on handle of a knife right-hand member scrape cutter hub, described cutter hub of scraping comprises interconnective blade and body of tool bit, described scraping is provided with opening groove in cutter hub, and described opening groove extends in body of tool bit from the left end of blade, the upper surface of described body of tool bit is provided with inclined-plane and inner concave, and the right-hand member of described body of tool bit is provided with point of a knife.

Further, the side of described body of tool bit has upper circular arc shaving, and another side of described body of tool bit has lower circular arc shaving.

Further, described upper circular arc shaving and lower circular arc shaving intersect at point of a knife.

Further, there is on the upside of the right-hand member of described opening groove upper deep-slotted chip breaker limit, on the downside of the right-hand member of described opening groove, there is lower arcuate slot limit.

Further, the surface of described handle of a knife has anti-skidding line.

Further, described point of a knife has angle A, and described angle A is 35 °～45 °.

Further, described angle A is 40 °.

The utility model has the advantages that:

1. the utility model structure is simple, easy to use, durable in use;

2. the utility model scope of application is relatively wide, and practicality is stronger;

3. volume of the present utility model less, be convenient to carry.

Except object described above, feature and advantage, the utility model also has other object, feature and advantage. Below with reference to figure, the utility model is described in further detail.

Accompanying drawing explanation

Form the part of this description, show preferred embodiment of the present utility model for understanding accompanying drawing of the present utility model further, and be used for principle of the present utility model is described together with description. In the accompanying drawings:

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

Fig. 2 is top view of the present utility model;

Fig. 3 be of the present utility model scrape cutter hub local structure schematic diagram; And

Fig. 4 be of the present utility model scrape cutter hub again one local structure schematic diagram.

Wherein, figure is labeled as:

10 it is handle of a knife, 20 it is blade for scraping cutter hub, 21,22 be body of tool bit, 221 be upper circular arc scraping, 222 be lower circular arc scraping, 223 be inclined-plane, 224 be inner concave, 23 be opening groove, 231 be upper deep-slotted chip breaker limit, 232 be lower arcuate slot limit, 24 for point of a knife.

Specific embodiment party formula

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Referring to figs. 1 to Fig. 4, a kind of novel scraper as shown in Figure 1, what comprise handle of a knife 10 and be arranged on handle of a knife 10 right-hand member scrapes cutter hub 20, described cutter hub 20 of scraping comprises interconnective blade 21 and body of tool bit 22, described scraping is provided with opening groove 23 in cutter hub 20, and described opening groove 23 extends in body of tool bit 22 from the left end of blade 21, as shown in Figure 2, the upper surface of described body of tool bit 22 is provided with inclined-plane 223 and inner concave 224, the right-hand member of described body of tool bit 22 is provided with point of a knife 24, described Novel scraping knife structure is simple, is convenient to processing and manufacturing.

As shown in Figure 3, the side of described body of tool bit 22 has upper circular arc shaving 221, and another side of described body of tool bit 22 has lower circular arc shaving 222, described Novel scraping cutter hub long-pending less, be convenient to carry.

The right-hand member of described upper circular arc shaving 221 and lower circular arc shaving 222 intersects at point of a knife 24 so that described novel scraper is easy to use, practicality is stronger.

Having upper deep-slotted chip breaker limit 231 on the upside of the right-hand member of described opening groove 23, have lower arcuate slot limit 232 on the downside of the right-hand member of described opening groove 23, the described novel scraper scope of application is relatively wide, and purposes is more.

As shown in Figure 2, the surface of described handle of a knife 10 has anti-skidding line, in use, avoid described novel scraper and user is produced potential safety hazard.

As shown in Figure 4, described point of a knife 24 has angle A, and angle A is 35 °～45 °.

Preferably, described angle A is 40 ° so that described point of a knife 24 not easily damages, durable in use.

These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations. All within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
