Scissor excavation and catch the instrument of wild crab
Technical field
The present invention relates to and catch crab instrument, particularly a kind of scissor excavation and catch the instrument of wild crab.
Background technology
Sandy beach in the wild, mud bank catch wild crab and there is certain difficulty, because wild crab is hidden darker on the one hand, multidigit is in silt depths, on the other hand, wild crab escape speed, once be found, escape soon, and how small wild crab is, add seizure difficulty, to being devoted to, crab is studied, the researcher of mud bank ecological Studies adds work difficulty.Mostly the wild little crab of existing seizure is to carry out excavating and catching, inefficiency with hand and some simple digging tools, is also easily crushed by crab, is unfavorable for carrying out of scientific research.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of scissor excavation and catching the instrument of wild crab, wild crab can be excavated and the wild crab of Quick Catch, prevent crab escape.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of scissor excavation and catch the instrument of wild crab, it is characterized in that, comprise cover body, the wall of described cover body is hollow structure, the top of described cover body is provided with two shear shanks, two described shear shanks are connected by screw, two shear shank free ends are respectively connected with scissors handle, one of them scissors is being provided with a scoop, any one shear shank stiff end is connected with folding parts by attaching parts, two described folding parts are respectively 1/4th spherical, and synthesize a hemispherical, two described folding parts are positioned at the wall chamber of cover body lower end hemisphere portion, in a state of use, two described folding parts leave in chamber, cover body lower end, in cover body end synthesis hemispherical, and are connected to form spherical structure with cover body lower end hemisphere portion, the material of described scoop is stainless steel.
Scissor excavation and catch the instrument of wild crab, it is characterized in that, the terminal edge of described cover body is provided with a circle fixture, is fixed in silt for making cover body.
Scissor excavation and catch the instrument of wild crab, it is characterized in that, face and the cover body lower end of described fixture are at an angle.
Scissor excavation and catch the instrument of wild crab, is characterized in that, the angle ranging from 15 ° ~ 30 °.
Scissor excavation and catch the instrument of wild crab, it is characterized in that, the material of described cover body is transparent plastics.
Scissor excavation and catch the instrument of wild crab, it is characterized in that, described scissors is provided with slip-proofing device inner side.
Scissor excavation and catch the instrument of wild crab, it is characterized in that, described slip-proofing device is the rubber blanket of one deck circular protrusions.
Usefulness of the present invention is: be 1. hood-shaped by catching the tool design of wild crab, can when finding wild crab the very first time covered, prevent it from escaping; 2. be provided with and can stretch and the folding parts of folding, and handled by scissor handle, after covering wild crab, it can be risen together with silt one digging on the one hand, escape after preventing crab from piercing silt, easy to use on the other hand; 3. be provided with a circle fixture at cover body terminal edge, fixture inserts silt, and cover body is more easily fixed in silt, more effectively prevents wild crab from escaping; 4. on scissors handle, be provided with a scoop, convenient wild crab of excavating in hole, catches rapidly after being also convenient to dig out crab, raises the efficiency.
Accompanying drawing explanation
Fig. 1 is scissor excavation of the present invention and the instrument schematic diagram catching wild crab;
Fig. 2 is scissor excavation of the present invention and the instrument catching wild crab schematic diagram when using.
The implication of Reference numeral in figure:
1. cover body, 2. attaching parts, 3. folding parts, 4. shear shank, 5. scissors handle, 6. fixture, 7. scoop.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Composition graphs 1, scissor excavation of the present invention and catch the instrument of wild crab, comprise cover body 1, described cover body 1 wall is hollow structure, described cover body 1 top is provided with two shear shanks 4, two described shear shanks 4 are connected by screw, two shear shank 4 free ends are respectively connected with scissors 5, one of them scissors is provided with a scoop 7 for excavating the wild crab of ensconcing in silt 5, any one shear shank 4 stiff end is connected with folding parts 3 by attaching parts 2, two described folding parts 3 are respectively 1/4th spherical, and synthesize a hemispherical, two described folding parts 3 are positioned at the wall chamber of cover body lower end hemisphere portion, described cover body 1 terminal edge is provided with a circle fixture 6, be fixed in silt for making cover body, the face of described fixture 6 and cover body 1 lower end are the angle of 15 °, described cover body 1 material is transparent plastics, light and easily to see cover body 1 clearly inner, the material of described scoop is stainless steel, described shear shank 4 can move in folding, drives sliding up and down of attaching parts 2, thus drives sliding up and down of folding parts 3 further, can handle the folding condition of folding parts 3.
Composition graphs 2, scissor excavation of the present invention and catch wild crab instrument in a state of use, two folding parts 3 leave in chamber, cover body 1 lower end, in cover body 1 end synthesis hemispherical, and are connected to form spherical structure with cover body 1 lower end hemisphere portion.
Scissor excavation of the present invention and catch the instrument of wild crab, except said structure, its difference is, the face of described fixture 6 and cover body 1 lower end are the angle of 30 °; Institute's scissors is provided with the pad (figure on not shown) of one deck with several circular protrusions inner side on 5, is same as anti-skidding.
Scissor excavation of the present invention and catch the instrument of wild crab, except said structure, its difference is, the face of described fixture 6 and cover body 1 lower end are the angle of 20 °.
Scissor excavation of the present invention and catch the instrument of wild crab, its using method is specific as follows:
When mud bank finds the cave of wild little crab in the wild, can excavate with the scoop 7 of instrument one end, in time excavating wild little crab, with instrument of the present invention, little crab is covered immediately, make it escape, then open shear shank 4 immediately, folding parts 3 are released in chamber, cover body 1 lower end, and close formation hemispherical, silt is dug by the folding parts 5 closed, can effectively prevent wild crab from escaping; After catching crab, then close shear shank 4, the folding parts 3 closed are opened, crab is put into vessel.
The instrument of the wild crab of seizure of the present invention puts into production, and tries out, respond well, is applicable to using widely.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
