Description
Technical field
The utility model relates to a kind of portable fish otolith hand sand instrument and carrying device.
Background technology
To fish classification and measure the fish age and often often judge by the morphological feature etc. of observing scale and otolith.Even come off because fish body scale is easily impaired in environment, regeneration scale cannot reflect really the fish body age, fish body otolith is difficult for damaged, is therefore the first-selection that we accurately judge the fish body age, certainly, if scale and otolith can be had more to convincingness in conjunction with meeting.
At present, in the time judging the age by otolith, need to carry out grinding process to it, only be polished to and to a certain degree just can obtain result more accurately.And conventional method is to take hand-held otolith to polish on sand paper, the method speed is slower, and quality is relatively not ideal enough, also can have the harm that staff is produced to damage.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is the portable fish otolith hand sand instrument and the carrying device that provide simple in structure, easy to use.
The technical scheme that the utility model adopts is:
A kind of portable fish otolith hand sand instrument, comprise the sleeve pipe of gripping handle, pressing lever and hollow, described sleeve pipe embeds and is fixed on gripping handle bottom, and described pressing lever penetrates and removable being fixed in sleeve pipe from sleeve bottom, and the bottom of described pressing lever is provided with flexible pressing face.
As the further improvement of technique scheme, described flexible pressing face is made up of native paraffin.
As the further improvement of technique scheme, the cross section of described sleeve pipe hollow space is regular hexagon, and the outer wall of described pressing lever is the regular hexagon mating with sleeve pipe hollow space.
As the further improvement of technique scheme, the top of described pressing lever outer wall is provided with elastic sheet metal, on described elastic sheet metal, is fixed with hemispherical projections, and described sleeve pipe is provided with the locating hole coordinating with projection.
As the further improvement of technique scheme, described gripping handle is provided with slip-resistant texture.
A kind of carrying device of portable fish otolith hand sand instrument, comprise chassis and upper cover, the middle part on described chassis is provided with instrument and places post, described instrument is placed post and is provided with handle putting hole, on described handle putting hole, be placed with gripping handle, described instrument is placed post and/or chassis is provided with some pressing lever putting holes, on described pressing lever putting hole, is placed with pressing lever.
As the further improvement of technique scheme, described each pressing lever putting hole is not of uniform size.
As the further improvement of technique scheme, described chassis is connected with upper cover threaded engagement.
The beneficial effects of the utility model are: the utility model utilizes flexible pressing face to replace staff to pin otolith to polish on sand paper, it is easy to use, can not produce damage to staff and otolith, carrying device is provided with some pressing lever putting holes, for placing the pressing lever of all size, because pressing lever and sleeve pipe are dismantled and assembled structure, experimenter can select different pressing levers to polish for the otolith varying in size, and has improved operating efficiency and quality of experiments.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model milling tools;
Fig. 2 is the installation diagram of sleeve pipe and pressing lever;
Fig. 3 is the schematic diagram of carrying device;
Fig. 4 is the structural representation on chassis.
Detailed description of the invention
As shown in Figure 1, a kind of portable fish otolith hand sand instrument, comprise the sleeve pipe 3 of gripping handle 1, pressing lever 2 and hollow, sleeve pipe 3 embeds and is fixed on gripping handle 1 bottom, pressing lever 2 penetrates from sleeve pipe 3 bottoms and removable being fixed in sleeve pipe 3, and the bottom of pressing lever 2 is provided with flexible pressing face 4.The material of this flexible pressing face 4 is taking native paraffin as main component, refine and form through techniques such as solvent dewaxing and de-oilings, suppleness is moderate, can highly imitate the suppleness of human finger, utilize in use this flexible pressing face 4 to press down otolith, otolith can be partly trapped in press surface fixing, improve the convenience of bruting process.According to the size of different otoliths, flexible pressing face 4 can be made different surface areas as required, to form all size model, and the different big or small Fish otoliths of being convenient to polish.
Preferably, the cross section of sleeve pipe 3 hollow spaces is regular hexagon, and the outer wall of pressing lever 2 is the regular hexagon mating with sleeve pipe 3 hollow spaces, and in the time that sleeve pipe 3 is inserted in pressing lever 2 top, orthohexagonal shape effectively prevents the rotation of pressing lever 2.
As shown in Figure 2, in the present embodiment, the top of pressing lever 2 outer walls is provided with elastic sheet metal 5, is fixed with hemispherical projections 7 on elastic sheet metal 5, and sleeve pipe 3 is provided with and projection 7 locating holes that coordinate 6.Pressing lever 2 sleeve pipe 3 interior when mobile elastic sheet metal 5 move until hemispherical projections 7 moves to locating hole 6 positions just thereupon, make pressing lever 2 with sleeve pipe 3 at axial restraint.When pressing lever 2 need to be removed, make it to leave locating hole 6 by lower convexity 7 gently.
Preferably, gripping handle 1 is made up of rubber mass, not cracky, and its skin has slip-resistant texture, and grip feeling is comfortable, and antiskid function is strong.
