Abstract
The utility model discloses a kind of use for laboratory scissors be convenient to loading end and used, comprise the first blade, the first in command, the second blade, the second in command and rotating shaft, described first blade is straight transitions between the center line of two sections of described rotating shaft two ends, or the angle between this center line of two sections is 175-180 °, angle on described second blade between the center line of two sections of described rotating shaft two ends is 140-160 °, and described second blade bends to the direction away from the described first in command near one section of the described second in command.The utility model by by the angle design of one of them blade between the center line of two sections of rotating shaft two ends for being less than 160 °, thus make two blades when opening, the height of its cutting mouth distance loading end is much smaller than conventional scissors, when cutting, cropped material need not be too high apart from loading end, its distortion is little, so improve cutting accuracy.
Description
Technical field
The utility model relates to a kind of scissors, particularly relates to a kind of use for laboratory scissors be convenient to loading end and used.
Background technology
Scissors is the twolip instrument of the sheets such as cutting cloth, paper, steel plate, rope, round steel or thread-shaped body, two-edged interlocks, can folding, specifically comprises two blades, two handles and rotating shaft, connected by rotating shaft between two blades, two handles are installed on the rear end of two blades respectively.
For a long time, scissors changes a lot of structure according to application demand, the length of such as blade and width, the size of handle and material etc., and these change the purposes extending scissors, make it apply convenient.But, all also there is a problem in conventional scissors, each exactly blade is straight transitions between the center line of two sections of rotating shaft two ends, or the angle between this center line of two sections be 175-180 ° basic close to straight transitions, this structure is in the ordinary course of things without any problem, but on desktop equivalent-load face during cutting, the height of the extended distance loading end of its cutting mouth that is between two blades is larger, cropped material can be made to be raised in cutting place so higher, thus cropped material appearance distortion to a certain degree can be made, and then reduce the accuracy of cutting.
Utility model content
The purpose of this utility model is just to provide a kind of use for laboratory scissors being convenient to loading end use that can improve cutting accuracy to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of use for laboratory scissors be convenient to loading end and used, comprise the first blade, the first in command, the second blade, the second in command and rotating shaft, described first blade is straight transitions between the center line of two sections of described rotating shaft two ends, or the angle between this center line of two sections is 175-180 °, angle on described second blade between the center line of two sections of described rotating shaft two ends is 140-160 °, and described second blade bends to the direction away from the described first in command near one section of the described second in command.
As preferably, the angle on described second blade between the center line of two sections of described rotating shaft two ends is 150 °.
Further, the upper inner side near the described first in command of the described second in command is provided with projection.Like this, just make the first in command and the second in command contact with each other when the first blade and the second blade overlap, be convenient to the complete closed of scissors.
The beneficial effects of the utility model are:
The utility model by by the angle design of one of them blade between the center line of two sections of rotating shaft two ends for being less than 160 °, thus make two blades when opening, the height of its cutting mouth distance loading end is much smaller than conventional scissors, when cutting, cropped material need not be too high apart from loading end, its distortion is little, so improve cutting accuracy, is particularly useful for laboratory.
Accompanying drawing explanation
Fig. 1 is the front view being convenient to when use for laboratory scissors that loading end uses is in closure state described in the utility model;
Fig. 2 is the front view being convenient to when use for laboratory scissors that loading end uses is in opening described in the utility model;
Fig. 3 is the front view of conventional scissors when being in opening.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the use for laboratory scissors being convenient to loading end use described in the utility model comprises the first blade 1, the first in command 4, second blade 2, the second in command 7 and rotating shaft 3, angle on first blade 1 between the center line of two sections of rotating shaft 3 two ends is 175-180 °, basic is straight transitions, angle on second blade 2 between the center line of two sections of rotating shaft 3 two ends is 150 °, also can be other angle between 140-160 °, and the second blade 2 bends to the direction away from the first in command 4 near one section of the second in command 7, inner side near the first in command 4 on the second in command 7 is provided with projection (unmarked in figure).The thumbhole 5 of the first in command 4 center and the finger insertion hole 6 of the second in command 7 center is also show, general insertion forefinger and middle finger in finger insertion hole 6 in figure.
As shown in Figure 2, during application, to treat that the material (not shown) of cutting is placed on loading end 9 (such as desktop, table top etc.), hand-held scissors carries out cutting, and the height of cutting mouth 8 (crossing namely between the first blade 1 and the second blade 2) the distance loading end 9 of scissors described in the utility model is less; Comparison diagram 3, if by conventional scissors, then its cutting mouth 10 is obviously greater than scissors described in the utility model apart from the height of loading end 9, is about about 3 times.So scissors described in the utility model can make materials to be clipped try one's best loading end 9 when cutting, thus makes the distortion of materials to be clipped less, and cutting accuracy is higher.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
