Abstract
The invention discloses a pincer type device for catching wild crabs efficiently. The pincer type device for catching the wild crabs efficiently comprises two scissor handles, wherein the two scissor handles are connected through a screw, the free ends of the two scissor handles are respectively connected with a scissor head, the ends, connected with the screw, of the two scissor handles are connected with opening and closing parts respectively, each opening and closing part is hemispherical, the two opening and closing parts can be combined to form a sphere, the screw is also connected with a pressing part, the pressing part is located in the spherical space formed by the opening and closing parts, and a pressing head is arranged at the free end of the pressing part. The pincer type device for catching the wild crabs efficiently has the remarkable advantages that due to the fact that the pressing part is arranged and a sucker device is arranged at the free end of the pressing head, when a large wild crab is found, the large wild crab can be pressed rapidly and firmly and be prevented from escaping; the hemispherical opening and closing parts can be opened or closed under the control of the scissor handles, the opening and closing parts are closed rapidly when the crab is pressed, the crab is dug together with silt, the wild crabs can be effectively caught, injuries to the crabs can not be caused, and workers are prevented from being pinched.
Description
Technical field
The present invention relates to catch the device of crab, particularly the wild crab device of the efficient seizure of a kind of jaw type.
Background technology
on sandy beach in the wild, mud bank, catch wild large crab (Carapax Eriocheir sinensis diameter 5-10cm) and there is certain difficulty, because on the one hand wild crab escape speed, once be found, escape soon, increased seizure difficulty, on the other hand, the large crab crab claw are strong strong, if free-hand seizure is easily crushed by the crab claw, cause certain seizure difficulty, increase work difficulty to the researcher who is devoted to crab research, mud bank ecological Studies.The wild large crab of existing seizure be mostly with hand and some simply excavate, the instrument of picking up catches, inefficiency, is also easily crushed by crab, is unfavorable for carrying out of scientific research.

The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, the thickness at the described folding parts place of mutually combining is 1 ~ 5mm.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, the thickness at the described folding parts place of mutually combining is 2 ~ 4mm.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, described combining pressing head is hemispherical, and described combining pressing head free end is provided with Acetabula device.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, described Acetabula device material is rubber.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, described shear shank, scissors handle, folding parts, pressing parts material are plastics.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, described scissors is provided with slip-proofing device inner side.
The wild crab device of the efficient seizure of a kind of jaw type, is characterized in that, described slip-proofing device is the rubber blanket of one deck with circular protrusion.
Usefulness of the present invention is: be 1. provided with pressing parts, and be provided with Acetabula device at combining pressing head free end, can rapidly it be pinned securely finding in wild large crab, prevent that it from runing away; 2. hemispherical folding parts can carry out folding by the manipulation of shear shank, close rapidly pinning after crab, and crab is risen together with silt one digging, effectively catch wild crab, and do not cause the damage of crab, also prevent that staff from being crushed; 3. this apparatus structure is simple, uses material environmental protection portable, can be widely used, and improves service efficiency.
Accompanying drawing explanation
Fig. 1 is that the wild crab device of the efficient seizure of jaw type of the present invention closes schematic diagram;
Fig. 2 is that the wild crab device of the efficient seizure of jaw type of the present invention is opened schematic diagram.
The implication of Reference numeral in figure:
1. shear shank, 2. scissors handle, 3. folding parts, 4. pressing parts, 5. Acetabula device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
In conjunction with Fig. 1, the wild crab device of the efficient seizure of jaw type of the present invention, comprise two shear shanks 1, described two shear shanks 1 connect by screw, an annular scissors of the each connection of free end of described two shear shanks 1 is 2, described two shear shanks, 1 connecting screw end connects respectively folding parts 3, described each folding parts 3 are hemispherical, and can be merged into one spherical, the thickness at described folding parts 3 places of mutually combining is 2mm, this thickness can efficiently insert in silt while contributing to folding parts 3 to close, and crab has been dug, and effectively prevents that it from escaping; Described screw is also connected with pressing parts 4, described pressing parts 4 are positioned at the diameter of Spherical Volume that folding parts 3 form, described pressing parts 4 free ends are provided with a hemispherical combining pressing head, described combining pressing head free end is provided with the Acetabula device 5 of quality of rubber materials, described pressing parts 4 for being pinned rapidly in finding wild large crab, prevent that it from runing away, the setting of Acetabula device 5 firm contact Carapax Eriocheir sinensis to a greater extent, effectively prevents that crab from slipping out and runing away.
