Specific embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment:
A kind of rat brain sampler, as shown in figures 1 to 6, including tube body 1, rotation lid 2 and materials needle 3, the top of tube body 1 and
Bottom is open, and rotation lid 2 is covered on 1 top of tube body and rotation lid 2 is rotatablely connected with respect to tube body 1, and materials needle 3 is located at tube body 1
Interior and top is connect with rotation 2 bottom of lid, and materials 3 lower part of needle is equipped with materials hook 4.
In this configuration, rotation lid 2 and tube body 1 are accomplished that rotation, that is, rotate the rotation that lid 2 and tube body 1 can be opposite,
And rotating lid 2 is lid conjunction at the top of tube body 1, meanwhile, 3 top of materials needle is connect with rotation lid 2, in this way, in rotation lid 2
When rotation, materials needle 3 is just as rotation lid 2 rotates.Materials needle 3 lower part be provided with materials hook 4, materials needle 3 with
When rotating the rotation of lid 2, materials hook 4 will be rotated and then.The effect of the rotation of materials hook 4 is embodied in when being used to obtain brain,
Materials hook 4 can catch on brain, rotate brain with materials hook 4, promote taken position and brain main body and other positions de-
From.Meanwhile after taken position is separated with other positions, under the action of drawing materials hook 4, brain can be rested in tube body 1.With
It is sampled convenient for transfer tube body 1.
In addition, being equipped with push button 5 at the top of the rotation lid 2, connected at the top of push button 5 and rotation lid 2, and connect
Position is corresponding with materials 3 position of needle.Pressing push button 5, the brain in tube body 1 can be released, to carry out correlation test.
In order to improve above-mentioned structure, as shown in Fig. 2, being equipped with spiral helicine spire 6, spiral at the top of the materials needle 3
Portion 6 is the top spiralization by materials needle 3, and the surrounding of spire 6 is connect with rotation 2 bottom of lid, such spire
Main body there is no with rotation lid 2 connect；Meanwhile elastic portion 7, certainly, bullet are equipped in 6 corresponding position of spire on rotation lid 2
Property portion 7 is less than the outer diameter of spire 6, it is ensured that elastic portion 7 is in the drop shadow spread of spire 6；Then push button 5 is set to
7 top of elastic portion.In this way, when pressing pushes button 5, due to the presence of elastic portion 7, so that the stroke of push button 5 is longer,
And since the inside of spire 6 is there is no fixed, can pressing pressure and unfold downwards in push button 5, thus will materials needle 3
It moves down, achievees the purpose that set forth above.Will push 5 bottom of button be set as spherical surface, can be easier by spire 6 to
Lower pressing.
In order to improve the elasticity of elastic portion 7, setting 7 thickness of elastic portion is less than the thickness of adjacent regions on rotation lid 2.
As a further improvement, recessed portion 8 is formed relative to side rotation lid 2 at 7 top of elastic portion, pushes button
5 are located in recessed portion 8, and push the covering of button 5 and be equipped with button set 9, and button set 9 is elastic component.In this way, pushing button in pressing
When 5, not only facilitate, is also convenient for push button 5 and springs back, consequently facilitating pressing repeatedly.
In order to improve the ability that tube body 1 obtains brain, bottom is equipped with crawl tooth 10, the crawl tooth in the tube body 1
10 ecto-entads are arranged obliquely.
In addition, being equipped at least two in 2 side wall of rotation lid grabs ear 11, one-handed performance may be implemented.That is, index finger is in
Finger, which is placed on, grabs at ear 11, then pushes button 5 with thumb press, achievees the purpose that above-mentioned.
The sampler structure of the utility model is simple, and operation is also easier, can be improved and obtains brain samples from rat
Efficiency.
