【Utility model content】
Main purpose of the present utility model is to provide a kind of simple rat brain slice device can effectively solve background skill
The problem of in art.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of simple rat brain slice device, including electric expansion bar, brain section plate and base, the chassis interior are set
Have an inner chamber, the bottom of the interior intracavitary is fixedly connected with electric expansion bar, the electric expansion bar output end by support with it is recessed
Being connected on the outside of groove, the groove both sides are fixedly connected with elongated piece and elongated piece top with groove top in same level,
The elongated piece of outside is connected with L-type groove and L-type groove is bonded with elongated piece of outer wall, is fixedly connected with the base top corner
There is cylinder, brain section plate is provided between the cylinder, the brain section plate both sides are connected by sliding sleeve with cylindrical outer side, described
It is provided with brain section plate and holds brain groove, cutting knife groove is formed between the brain section plate.
Further, the electric expansion bar is miniature electric expansion link.
Further, the periphery is provided with exact scale.
Further, the base top and groove top are in same level.
Further, the sliding sleeve side is connected with tightening knob.
Compared with prior art, the utility model has the advantages that：By the setting of electric expansion bar to cutting
Knife cut after rat brain slice, by controlling electric expansion bar, rat brain slice on groove and groove is integrally risen, be not required to
Brain section plate is removed, just allows staff easily to take rat brain slice away, without damaging, by holding setting for brain groove and groove
Put and the appearance brain groove shape on multilayer brain section plate is designed to place brain to be cut from top to down until in groove, and it is wherein several
Individual brain section plate is identical with brain maximum length to be cut and width, can play a part of support to brain to be cut, be easy to cut into slices, and groove
Entirety include elongated piece be less than on each brain section plate appearance brain groove entirety, can allow groove hold brain groove in move up and down,
Brain section is shifted out, can be by cylinder by the setting of cylinder and sliding sleeve according to the brain section of requirement of experiment different-thickness
Exact scale, moving sliding sleeve positions the different thickness of brain section, is fixed rotating tightening knob, meets staff
Demand, without the different-thickness according to requirement of experiment, look for the rat brain slice mould to match, save the time,
Both outer wall is bonded with elongated piece of setting by L-type groove, that is, prevent outside grieshoch from entering inner chamber, electric expansion bar is caused
Influence, groove top can be made in same level, smoothly to support brain to be cut with base top again, be easy to cut out uniformly
Brain section.
