Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a plant group DNA draws kit based on magnetic bead method dismouting bar magnet of being convenient for, including test tube 1, the upper end fixedly connected with test tube 1 mouth of pipe is followed 2, test tube mouth is along 2 upper end fixedly connected with mounting 3, the one end fixedly connected with locating part 4 of mounting 3, the inside swing joint of mounting 3 has fixture block 5, mounting 3 and fixture block 5 are connected for the block, one 6 of the upper end fixedly connected with connecting piece of

fixture block

5, 5 side fixedly connected with agitator sleeve 7 of fixture block, fixedly connected with spiral bulge 8 on the inner wall of agitator sleeve 7, swing joint has bar magnet 9 on the inner wall of agitator sleeve 7, spiral groove 10 has been seted up on bar magnet 9's the outer wall, spiral groove 10 and spiral bulge 8 are threaded connection, two 11 of the upper end fixedly connected with connecting piece of bar magnet 9, test tube 1's lower extreme fixedly connected.

Further, the test tube mouth is less than test tube 1's internal diameter along the internal diameter of 2, and the diameter of fixture block 5 is greater than the test tube mouth along the internal diameter of 2, is favorable to letting stirring cover 7 put in test tube 1 the time, and the test tube mouth can block fixture block 5 along 2.
