The art development cuvette rotary heating station according to claim 6, characterized in that: the locking part comprises a locking rod for locking, a limiting rod is fixedly connected to the surface of the sleeve, the inner end of the locking rod is movably inserted into the limiting rod and penetrates into the sleeve, a wafer for limiting is fixedly connected to the surface of the locking rod, a second spring is wound on the surface of the locking rod, the two ends of the second spring are fixedly connected to the inner wall of the limiting rod and the outer wall of the wafer respectively, a butt joint block is fixedly connected to the surface of the movable rod, and a hole matched with the locking rod is formed in the inner wall of one side, deviating from the movable rod, of the butt joint block.

8. The art development cuvette rotary heating station according to claim 7, wherein: the inner end of the locking rod is designed in a spherical shape, and a chamfer is arranged on one side, close to the placing disc, of the butt joint block.

9. A technology development test tube rotary heating table according to claim 8, characterized in that: the telescopic surface still is provided with the pressing piece that is used for pressing the test tube, the pressing piece is close to telescopic one side fixedly connected with upset seat, the inner wall of upset seat rotates and is connected with the axostylus axostyle, the both ends fixedly connected with slider of axostylus axostyle, the surface winding of axostylus axostyle has the torsional spring, and the both ends fixed connection of torsional spring is at the inner wall of upset seat, the slider can be in the spout that the sleeve inner wall was seted up spacing slip, fixedly connected with spring three between spout inner wall and the slider outer wall.

10. A method of technically developing a cuvette rotary heating stand according to claim 9, comprising the steps of:

s2, after the test tube is inserted into the placing groove, the pressing piece rotates under the action of the torsion force of the torsion spring, so that the pressing piece is turned over to be in a horizontal state, the pressing piece presses the top end of the test tube, and meanwhile, the pressing piece is controlled to be capable of pressing the top end of the test tube all the time under the elastic action of the spring III,

s3, after the test tube is fixed, the movable rod, the first rotating rod and the first grinding sheet are controlled to move downwards by pressing the pressing block, the butt joint block moves downwards when the pressing block descends, a chamfer at one side, close to the placing disc, of the butt joint block is abutted to the inner end of the locking rod, the locking rod moves towards the direction of the limiting rod, when the first grinding sheet is in direct contact with the second grinding sheet, the butt joint block is inserted into a hole formed in the inner wall of the butt joint block under the elastic control of the second spring, and the first rotating rod is fixed,

s4, after the position of the first rotating rod is fixed, the motor is started to work, the motor controls the third rotating rod and the second gear to rotate, the first gear is controlled to rotate when the second gear rotates, at the moment, the first grinding sheet which is in contact with the second grinding sheet group can control the corresponding first rotating rod to rotate, and the placing disc and the heating sheet are controlled to rotate simultaneously,

s5, after the placing disc and the heating plate rotate, the corresponding control element is controlled, the output element on the sensor in the control element is used for sending a signal, the sensor in the heating plate receives and processes the signal, the heating plate is controlled to heat, the heating plate rotates while heating, liquid in the water tank can be rapidly heated, and the heating of the test tube is realized,

s6, after the heating is accomplished, close the motor, and through controlling the control element that corresponds, stop the heating plate the heating, through outside pulling locking lever afterwards for in the locking lever breaks away from the hole, under the elastic control through spring one this moment, make movable rod control bull stick one remove, make dull polish piece one and dull polish piece two relieve the contact, press the pressing disc through the upset at last, both can realize taking fast to the test tube.
