Abstract
The utility model discloses a kind of fixture of testing with live body crab, comprise a fixture for fixing crab body rear end and two nestings for fixing crab pliers, fixture is connected by elastic connecting strip with nesting, fixture is made up of the upper sandwich part for being pressed in crab body upper casing and the lower sandwich part for being pressed in crab body lower casing, in a certain angle between upper sandwich part and lower sandwich part, its advantage is better to the fixed effect of crab when testing, nesting difficult drop-off, can ensure carrying out smoothly of experiment.
Description
Technical field
The utility model relates to a kind of crab fixture, particularly relates to a kind of experiment live body crab fixture.
Background technology
In school, graduate scientific research activity, the research of research crab to aspects such as disease, molecular biology, morphology is all significant.When testing crab, because the large pliers of crab is rich in aggressiveness, damage to person can be caused to experimenter, so need to carry out binding process in advance to the large pliers of crab.Current modal binding mode is the joint of two the large pliers first entangling crab with rubber band, and then tests.There is following problem in above-mentioned traditional execution mode: owing to only entangling the large pliers joint of crab, so the large pliers quilt cover of crab still can experiencing small oscillating movements after living, binding loosely; Rubber band is easy to come off, and fixed effect is poor; In order to be wound around multi-turn rubber band, need professional to carry out bindings, difficulty is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good fixing effect, experiment live body crab fixture that operation easier is low.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fixture of testing with live body crab, it is characterized in that comprising a fixture for fixing crab body rear end and two nestings for fixing crab pliers, described fixture is connected by elastic connecting strip with described nesting, described fixture is made up of the upper sandwich part for being pressed in crab body upper casing and the lower sandwich part for being pressed in crab body lower casing, in a certain angle between described upper sandwich part and described lower sandwich part.
Described fixture also comprises an intermediate, and described elastic connecting strip is connected on intermediate, and described upper sandwich part and described lower sandwich part are all connected on intermediate.These parts of intermediate can increase the contact area of crab rear end and fixture, and fixture is not easily slidably reciprocated, and increase fixed effect.
Described upper sandwich part to include on first clamping piece on clamping piece and second, and described lower sandwich part includes first time clamping piece and second time clamping piece; In a certain angle between clamping piece on clamping piece and second on first, in a certain angle between first time clamping piece and second time clamping piece; On described first, on clamping piece, second, clamping piece, first time clamping piece and second time clamping piece are all connected on intermediate.The setting of four clamping bodies can increase the contact area with crab shell, makes fixing more firm.
On described first, on clamping piece, second, clamping piece, first time clamping piece and second time clamping piece are shaft-like.Shaft-like clamping piece reducing because fixture blocks the contact area increasing clamping piece and crab shell under to the prerequisite doing the impact that experiment causes, can strengthen fixed effect.
Angle on described the first upper clamping piece and second between clamping piece is 60 degree, and the angle between first time described clamping piece and second time clamping piece is 60 degree.Arrange like this and sandwich part can be made not easily to move, more firmly.
The angle of described upper sandwich part and lower sandwich part is 30 degree ~ 60 degree.The scope of 30 degree to 60 degree can wrap crab rear end part, and fixture is not easily slidably reciprocated, and increases fixed effect.
Described nesting is cylindrical generally, the inner hollow of described nesting; The front end of nesting is near the knee of crab pliers, and the rear end of nesting is away from the knee of crab pliers; The front end bore of described nesting is greater than the rear end bore of described nesting.After crab clamp brachiocylloosis, the diameter in tong arm knee is less than the diameter of tong arm middle, the form of the pliers that can more coincide of nesting caliber size, can strengthen binding effect.
Described nesting is made up of elastomeric material.Elastomeric material can be applicable to the large pliers of crab of different size, and good than stiff nesting of fixed effect.
Described upper sandwich part and lower sandwich part are all coupling on intermediate, are also provided with the back-moving spring for automatically closing upper sandwich part and lower sandwich part between described upper sandwich part and lower sandwich part.The power that fixture can be made initiatively to produce a compressing crab shell is set like this, increases fixed effect.
Described intermediate has the radian matched with crab body rear end.The radian of intermediate arranges and can make intermediate not easily crab rear end slip relatively, makes fixed effect better.
Compared with prior art, the utility model has the advantage of: during use, two nestings are inserted in two large pliers joints respectively, the tong arm of the large pliers of crab can not be mentioned, the clamp of the large pliers front end of crab leans against belly thereupon, cannot damage experiment personnel, the fixture place being in crab rear end is then connected to by elastic connecting strip.Nesting is under the effect of the pulling force of elastic connecting strip, and make on the one hand the large pliers of crab be fixed on the belly of crab motionless, fixed effect is better; Make the nesting difficult drop-off on the large pliers of crab on the other hand, ensure carrying out smoothly of experiment.
