Referring to fig. 1 to 5, the present invention provides a technical solution: the test tube rack for preparing the exosome of the targeted osteosarcoma cell in the embodiment mainly comprises the following structures: the upper end of base 1 is close to the fixed fagging 2 that is provided with two sets of symmetries of border position department, and the top of two sets of fagging 2 is connected with back shaft 3, the surface both ends of back shaft 3 are close to fagging 2 position punishment and do not fixedly be provided with first rotation wheel 4 and second and rotate wheel 5, first rotation wheel 4 and second rotate and are provided with multiunit rack 8 between the wheel 5 edge, and it has magnetic shaft 7 to alternate in the middle of the top of rack 8, magnetic shaft 7 is located first rotation wheel 4 and second and rotates wheel 5 edge both ends and all be provided with retainer plate 6, rack 8 hangs on first rotation wheel 4 and second rotation wheel 5 through magnetic shaft 7, the bottom of base 1 is provided with four sets of universal wheels 12, all set up recess 9 in the middle of the edge around the surface of base 1, and the fixed axle 10 that is provided with in the middle of recess 9, running-board 11 has been cup jointed on the fixed axle 10.

Utilize four groups of universal wheels 12 to remove this reserve test tube rack to the assigned position, running-board 11 includes footboard portion and installation department, the installation department is the rubber material and cup joints on fixed axle 10, then step on running-board 11 to the foot down, make running-board 11 rotate sixty degrees backward on the fixed axle 10 of recess 9, make the bottom and the ground contact increase frictional force of running-board 11, thereby fix this reserve test tube rack, if need remove, then step on running-board 11 to the foot that makes progress, with running-board 11 forward rotation sixty degrees, running-board 11's rotation range is thirty degrees back and forth.

Rack 8's top includes with 7 assorted axle sleeve portions 801 of magnetic force axle, the surface of magnetic force axle 7 is provided with a plurality of groups magnetite, the iron core has all been inlayed to the corresponding position department of internal surface of axle sleeve portion 801, magnetic force axle 7 is located 5 marginal both ends of first runner 4 and second runner, make magnetic force axle 7 and rack 8 along with rotating, and rack 8's top sets up 7 assorted axle sleeve portions 801 of magnetic force axle, magnetic force axle 7's surface is provided with a plurality of groups magnetite, the iron core has all been inlayed to the corresponding position department of internal surface of axle sleeve portion 801, magnetite and iron core inter attraction, reduce rocking of rack 8 when getting and taking reserve test tube, but rack 8's gravity is greater than the appeal between iron core and the magnetite, so when first runner 4 and the rotation of second runner 5, rack 8 is decurrent state all the time.

The placing rack 8 is provided with a plurality of groups of linearly arranged placing grooves 802, the placing grooves 802 sequentially comprise a first groove 8021, a second groove 8022, a third groove 8023 and a fourth groove 8024 from large to small according to the size, the upper side and the lower side of the first groove 8021 are respectively provided with the second groove 8022, the third groove 8023 and the fourth groove 8024, and the placing grooves are regularly arranged to facilitate distinguishing standby test tubes.

The outer surface of rack 8 is provided with built-in groove 803 near standing groove 802 position department, and the inside of built-in groove 803 is provided with spring 805, the free end fixed mounting of spring 805 has semicircle board 804, semicircle board 804 extends to the centre of standing groove 802, and the area of semicircle board 804 is half of the cross-sectional area of standing groove 802, in rack 8 from the top down process, semicircle board 804 is located the centre of standing groove 802 all the time because the elasticity of built-in groove 803 in spring 805, can avoid reserve test tube lid to empty the leakage that leads to the exosome culture of target osteosarcoma cell in the rotation process, when placing the test tube with the bottom of test tube gently push semicircle board 804 to built-in groove 803 inside can, place and accomplish later half circular plate 804 because the elasticity of spring 805 is automatic to bounce back.

The working principle is as follows: in actual work, the standby test tube placement rack is moved to a designated position by four groups of universal wheels 12, the pedal plate 11 comprises a pedal part and a mounting part, the mounting part is made of rubber materials and is sleeved on the fixed shaft 10, then the pedal plate 11 is stepped on by a downward foot, the pedal plate 11 rotates sixty degrees backwards on the fixed shaft 10 of the groove 9, the bottom end of the pedal plate 11 is in contact with the ground to increase friction force, the standby test tube placement rack is fixed, if the standby test tube placement rack needs to be moved, the pedal plate 11 is stepped on by an upward foot, the pedal plate 11 rotates sixty degrees forwards, and the rotation range of the pedal plate 11 is thirty degrees forwards and backwards; after the test tube rack is moved to a specified position and fixed, the first rotating wheel 4 and the second rotating wheel 5 are rotated, the magnetic shaft 7 penetrates through the top of the rack 8, the magnetic shaft 7 is located at two ends of the edges of the first rotating wheel 4 and the second rotating wheel 5, the magnetic shaft 7 and the rack 8 rotate along with the rotation, a shaft sleeve part 801 matched with the magnetic shaft 7 is arranged at the top end of the rack 8, a plurality of groups of magnets are arranged on the outer surface of the magnetic shaft 7, iron cores are embedded in corresponding positions of the inner surface of the shaft sleeve part 801, the magnets and the iron cores attract each other, the shaking of the rack 8 when a standby test tube is taken is reduced, but the gravity of the rack 8 is larger than the attraction force between the iron cores and the magnets, and therefore when the first rotating wheel 4 and the second rotating wheel 5 rotate, the rack 8 is always in a downward state; the placing grooves 802 of the placing rack 8 are divided into a plurality of grooves, namely a first groove 8021, a second groove 8022, a third groove 8023, a fourth groove 8024 and more grooves 8024, which are regularly arranged to facilitate the distinction of standby test tubes, and the first groove 8021, the second groove 8022, the third groove 8023 and the fourth groove 8024 are all inclined; in the process from top to bottom of the placing rack 8, the semicircular plate 804 is always located in the middle of the placing groove 802 due to the elastic force of the spring 805 in the built-in groove 803, so that leakage of an exosome culture of a targeted osteosarcoma cell caused by toppling of a standby test tube cover in the rotating process can be avoided, the semicircular plate 804 can be slightly pushed to the inside of the built-in groove 803 by the bottom of a test tube when the test tube is placed, and the semicircular plate 804 automatically rebounds due to the elastic force of the spring 805 after the test tube is placed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
