Description

Amphibious crab catching device

Technical Field

The invention relates to the technical field of fishing gear, in particular to an amphibious crab catching device.

Background

Most species of crabs live in the sea or near-sea, and some live on fresh water or land. They rely on female crabs to produce small crabs, which produce many eggs each time, and the number of eggs can reach more than millions. Crabs rely on the earth's magnetic field to determine direction. The number of such biogenetic materials is complex and varies widely, often as many as 100 pairs. Common crabs include hairy crabs (river crabs, hairy crabs and clean water crabs), portunids and the like. The resources of the crabs in China are very rich,

with the improvement of living standard, the number of edible crabs is increased, and when wild or workers breed crabs are caught, in order to prevent clamping and catching personnel by claws and toes of the crab, a crab catching tool needs to be designed, so that the crab catching tool is beneficial to catching the crabs.

Disclosure of Invention

The invention aims to provide an amphibious crab catching device aiming at the existing problems.

The invention is realized by the following technical scheme: the amphibious crab catching device comprises a housing, wherein the upper part of the housing is connected with a handle sleeve, the inner cavity of the handle sleeve penetrates into the housing, a push-pull rod is arranged in the handle sleeve, the upper end of the push-pull rod is connected with a handle, the lower end of the push-pull rod is arranged at the inner top of the housing and is uniformly fixedly connected with a hinge seat in a triangular mode, the hinge seat is connected with an upper blunt end of a claw tooth through a pin shaft, the lower tip of the claw tooth extends out of the housing, the outer cambered surface of the claw tooth is integrally connected with a sliding rail, the sliding rail is clamped with.

As a further improvement to the scheme, the cover is hemispherical, the lower part of the cover is a round opening, and a plurality of holes are formed in the wall of the cover.

As a further improvement to the above scheme, the inner cavity wall of the handle sleeve is provided with three arc-shaped grooves, and a plurality of semicircular concave pits are arranged on the arc-shaped grooves at intervals.

As a further improvement of the above scheme, the surface of the push-pull rod is embedded with a top bead corresponding to the semicircular concave pit, a columnar hole is further formed in the push-pull rod, the columnar hole is formed in the push-pull rod on the inner side of the top bead, a spring is installed in the columnar hole, one end of the spring is connected with the bottom of the columnar hole, and the other end of the spring is connected with the top bead.

As a further improvement to the scheme, three sliding blocks are clamped on the sliding rail integrally connected with the outer arc surface of each claw tooth at intervals.

As a further improvement to the above solution, when a crab is found, the cover of the device is placed above the crab, the push-pull rod is firstly pressed downwards, the top bead slides in the arc-shaped groove of the handle sleeve, the lower end of the sliding block slides in a groove of the sliding block through three claw teeth and a sliding rail which are connected by a hinge, the three claw teeth extend out of a round opening at the lower part of the housing and are opened, then the crab is aligned, the push-pull rod is lifted to drive the claw teeth to close to clamp the crab, and when the top ball arranged on the push-pull rod slides in the arc-shaped groove of the handle sleeve, the top ball can sink into the semicircular concave pit of the handle sleeve along with the tension pressure of the spring every time the top ball slides for a certain distance to prevent the handle sleeve and the push-pull rod from sliding relatively, thus the opening and closing angles of the three claw teeth can be kept, and the hole arranged on the cover shell is convenient for catching crabs in water, the water in the housing is communicated with the water outside the housing, so that no pressure difference is ensured, and the crab can be conveniently caught.

Compared with the prior art, the invention has the following advantages: the crab catching device has the advantages of compact structure, reasonable design, novel and unique thought, and capability of being operated by personnel, crabs can be caught at the edge of a pool ditch or in water, the three claw teeth are triangular to clamp the crabs, so that silt can be leaked, and the operation in water is not hindered.
