Abstract

The utility model relates to a safety scraper, comprising a gripping unit and a blade at the front end of the gripping unit. The utility model is characterized in that the gripping unit (1) comprises a first shell (11) and a second shell (12) fitted-positioned with the first shell (11), the blade (3) is extension-type, positioning inside the cavity between the first shell (11) and the second shell (12). Compared with the prior art, the utility model has the advantages that: the blade of the utility model can be adjusted to control the extension and positioning; when the scraper is unused, the blade can be retracted into the cavity of the gripping unit; when the scraper is used, the blade can be extended out; therefore, not only the normal use is ensured but also the hidden danger of injuring others is effectively avoided.

Description

A kind of safety-type scraper

Technical field

The utility model relates to the instrument on a kind of clean article surface, relates in particular to a kind of Clean-safety-type scraper.

Background technology

The existing scraper kind that is used to remove metope, desktop, road surface or other article surface burs is a lot, external form is different, but generally all comprise gripping member and be arranged at the blade that grips the end of seing before, blade is generally all fixed, not flexible, can not change easily, as Chinese utility model patent: ZL93201654.5, a kind of " structure improved scraper " (its publication number: CN2148794Y) is disclosed, just like Chinese utility model patent: ZL98219095.X, denomination of invention is " scraper " (its publication number: CN2354700Y).

Above-mentioned patent is all improved on gripping member, make that operation is easier and comfortable when using, but fixed blade setting is not improved, bring inconvenience not overcome thus, the first, blade is sharper, scratches other people easily in the time of idle, owing to there is not attached protection structure, blade also damages easily; The second, blade is difficult for changing, and after the general breaks down, whole scraper just abandons, and the product loss is big, is unfavorable for environmental protection; The 3rd, when transportation and storage, blade takes up space bigger, increases transportation and storage cost.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of difficult scuffing other people, the safety-type scraper of environmental protection at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this safety-type scraper, comprise gripping member and be positioned at the blade of described gripping member leading section, it is characterized in that described gripping member comprises that first housing reaches second housing that cooperates assembling with this first housing, be provided with a telescopic sliding part of arch movably between described first housing and described second housing, this sliding part leading section is connected with one and is suitable for the tool rest that described blade is settled, described sliding part is provided with button portion, accordingly, described first housing is provided with and is fit to the endoporus that described button portion moves forward and backward, and described button portion exposes to described first housing, by described arch sliding part, described blade is arranged in the cavity between described first housing and described second housing telescopicly.

Locate for ease of blade during use, also be provided with protuberance on the described sliding part, accordingly, described first housing is provided with the side opening that is fastened with described protuberance.

Locate for ease of blade when idle, described sliding part rearward end is provided with feet, and accordingly, described second inner walls is provided with the stop part that stops described feet.

Compared with prior art, advantage of the present utility model is: blade of the present utility model can be regulated and control its flexible location, in the time of idle, but blade indentation gripping member inner chamber, when using, blade is extended next, is guaranteeing to have avoided scratching other people hidden danger effectively under the normal prerequisite of using like this; Also greatly reduce simultaneously because blade exposes the probability that causes blade impaired; Moreover when transportation and storage, blade indentation gripping member inner chamber has reduced taking up space, and has reduced the cost of transportation and storage; At last, after the breaks down, can change from tool rest easily, make the loss of gripping member reduce, be beneficial to environmental protection.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment: referring to figs. 1 to Fig. 6, safety-type scraper in the present embodiment comprises gripping member 1 and is positioned at the blade 3 of gripping member 1 leading section, gripping member 1 comprises first housing 11 and cooperates second housing 12 of assembling with first housing 11, consider easy to assembly, first housing 11 also is furnished with first tabling piece 13 chimeric with it, second housing 12 also is furnished with second tabling piece 14 chimeric with it, is arranged in the cavity between first housing 11 and second housing 12 blade 3 extension types.

Telescopic structure is specific as follows, also be provided with an arch sliding part 2 between first housing 11 and second housing 12, sliding part 2 leading sections are connected with one and are suitable for the tool rest 4 that blade 3 is settled, tool rest 4 is provided with a pair of buckling parts 42 and a pair of card division 41 that is suitable for blade 3, and blade 3 is provided with the draw-in groove 31 of card division 41 screens simultaneously; Sliding part 2 is provided with button portion 21 and a pair of protuberance 22, protuberance 22 is positioned at button portion 21 both sides, protuberance 22 has a motion inclined-plane 221 and a vertical plane 222, accordingly, first housing 11 is provided with and is fit to the contralateral exposure 112 that endoporus 111 reaches and protuberance 22 is fastened that button portion 21 moves forward and backward, equally, a contralateral exposure 112 is positioned at endoporus 111 both sides, and button portion 21 exposes to first housing 11; Sliding part 2 rearward end are provided with feet 23, and accordingly, second housing, 12 inwalls are provided with the stop part 121 of barrier support pin 23.

Telescopic structure can also adopt structure common in the prior art to substitute, and enumerates no longer one by one here.

Operation principle: when idle, in the blade 3 indentation gripping members 1, in the time of use, firmly promote button portion 21 forward, sliding part 2 moves forward, along the inclined-plane 221 that moves of protuberance, side opening 112 and protuberance 22 clampings, thereby location sliding part 2, scraper just can be devoted oneself to work like this; Finish using, firmly push button portion 21 downwards, because sliding part 2 arches have certain elasticity, cause protuberance 22 to break away from side opening 112, give a hard push backwards then and move button portion 21, run into until the feet 23 of sliding part till the block piece 121 of second housing, remove external force, blade 3 is with regard to indentation gripping member 1 like this, and sliding part 2 returns to state when leaving unused.
