Abstract

The utility model relates to a series combined putty scraper with a universally-used flexible handle. The utility model is characterized in that: the utility model consists of a series scraper and a handle. The series scraper consists of a knife blade and a knife handle. The shape and the size of all the knife handles are the same; the handle is provided with a knife handle cavity, and a positioning structure A is arranged on the knife handle cavity; the positioning structure A is in cooperation with a correspondent positioning structure B on the knife handle so as to achieve axial-direction positioning connection. The utility model designs a series combined putty scraper with a one-handle multiple-knives structure. The cooperation between the handle and a plurality of knifes is realized through the crossing-over connection of the knife handle and the handle as well as the positioning structure (or fixed structure). The positioning structure can not only guarantee the stability and reliability of the scraper during working, but also ensures the convenience in knife exchange. The utility model therefore overcomes the defects of series combined putty scraper due to repeated operation, and greatly reduces the packaging volume of the series components. The utility model ulteriorly facilitates the transportation, carrying and storage for the utility model.

Description

The series of combination hacking-out knife of band universal handle

Technical field

The utility model relates to manual hardware ﹠ toolss such as hacking-out knife, is specifically related to a kind of series of combination hacking-out knife structure with general flexible handle.

Background technology

Hacking-out knife often uses in installation, fitting-out work and paint application as a kind of manual hardware ﹠ tools.Existing hacking-out knife generally is made of blade and the handle that is fixed on handle of a knife, the handle of this scraper is permanent fixedlying connected with blade, if manufacture one group of serial hacking-out knife that blade size is different with specification, need on each blade, to fix a handle, more convenient although this way uses, must need a plurality of handles unexpectedly, it is bigger not weigh volume like this, and carry, collect also inconvenience, in case breaks down, it is discarded together then to connect handle.From another angle, the serial hacking-out knife of one group of different size in actual use, can not use simultaneously generally speaking for a people, handle of fixed installation neither be essential on each blade concerning serial hacking-out knife in other words, for this reason, the utility model from the use of serial hacking-out knife, pack, carry, analysis-by-synthesis such as collection, conceived a kind of series of combination hacking-out knife, to improve prior art with general flexible handle.

Summary of the invention

For achieving the above object, the technical solution adopted in the utility model is: a kind of series of combination hacking-out knife with general flexible handle, to form by one group of series scraper and a handle, and scraper is made up of blade and handle of a knife, and the shape of each handle of a knife is identical with size; Handle is provided with the handle of a knife chamber, and the handle of a knife chamber is provided with location structure A, and this location structure A cooperates the formation axial location to be connected with the location structure B of handle of a knife corresponding site.

Related content in the technique scheme is explained as follows:

1, described " one group of series scraper " is meant the scraper series of being made up of the hacking-out knife of two kinds of different sizes and size at least, and the different size of scraper is formed by blade shapes, size or its structure.Here it is emphasized that in described one group of series scraper allows two kinds of specifications and measure-alike scraper to exist.

2, described " handle " is meant and is versatility handle arrangement of above-mentioned serial scraper outfit.

In the technique scheme, described location structure A and location structure B are a kind of upperseat concept descriptions, specifically include following situation of change:

1, location structure A is the elastic bumps structure, and location structure B is hole or depression, and when handle of a knife inserted the handle of a knife chamber, the elastic bumps structure headed in hole or the depression from the side.Such as, shown in accompanying drawing 1 and accompanying drawing 2, the elastic bumps structure is made of the steel ball and the spring that embed in the handle body, and when handle of a knife inserted the handle of a knife chamber, steel ball headed in the hole or depression of handle of a knife from the side.

2, location structure A is the movable latch structure, and location structure B is hole or breach, when handle of a knife inserts the handle of a knife chamber, movable latch is inserted the hole or the breach of handle of a knife.

3, location structure A is a bolt structure, and location structure B is hole, groove or breach, when handle of a knife inserts the handle of a knife chamber, screw is stretched into hole, groove or breach.

4, location structure A is a chip architecture of the spring, and location structure B is plane or depression, and when handle of a knife inserted the handle of a knife chamber, spring leaf relied on elastic force roof pressure position tool shanks.

5, location structure A is colluded with button by elasticity and constitutes, and location structure B is hole button or groove button, and when handle of a knife inserted the handle of a knife chamber, elasticity was colluded and anchored the position with hole button or groove and cooperates the disengaging of pressing button hook.

In the technique scheme, can bear slight knocking in order to make hacking-out knife, inlay an end iron at the root of handle, end iron extends to handle of a knife chamber root in handle, and contacts with handle of a knife.In order to make hacking-out knife be convenient to hang, laterally be provided with at the root of handle and wear hanging hole.In order to make handle have good hand feeling, handle to be made inside and outside double-deck envelope form, its ectomesoderm is a soft layer.

The utility model operating principle is: one group of series hacking-out knife is designed to a handle multitool structure, and the handle of a knife of a plurality of scrapers made with a kind of specification and form, be connected with the interchangeability of handle by handle of a knife in use and the multiple tool cooperation of location structure (or fixing) realization one handle, thereby solve the defective that serial hacking-out knife handle repetition is brought.Its location structure should guarantee the scraper stability and the reliability in when work, guarantees the convenience of tool changing again.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, the utility model with an original cutter one shank type fixedly hacking-out knife be improved to a handle multitool structure, therefore concerning serial scraper, significantly reduced the serial component packaging volume, make transportation, carry and collect convenient.

2, the utility model serial component is owing to saved a plurality of handles, and manufacturing cost descends thereupon, has also avoided some unnecessary wastes.

3, the utility model adopts general handle of a knife chamber and location structure to cooperate with handle of a knife, and the plug tool changing is flexible, easy to use, and assembling and positioning is reliable.

4, the utility model adopts the mode of inlaying an end iron at the root of handle, makes hacking-out knife can bear slight percussion power, can bring into play the scraper effect better like this.

In sum, the angle that the utility model disposes from a handle multitool is improved existing scraper and is improved, and analysis-by-synthesis has obtained tangible good effect under the prerequisite that does not influence serial scraper use, therefore creative.
