Fourth embodiment, on the basis of the first embodiment, referring to fig. 2 and 3, a worker rotates the first shaft 22 mounted on the first bracket 5 by driving, the first shaft 22 rotates and drives the first worms 23 slidably mounted at both ends of the first shaft 22 to rotate, the first worms 23 at both ends of the first shaft 22 are symmetrical to each other, so that if the first shaft 22 rotates and drives the first worms 23 to rotate, one of the first worms 23 drives the first worm wheel 24 mounted in cooperation therewith to rotate, the other first worm wheel 24 drives the first worm wheel 24 mounted in cooperation therewith to rotate in the opposite direction, the first worm wheel 24 rotates and drives the second disk 26 fixedly mounted with the same center to rotate, during a period when the worker does not rotate the first shaft 22, the second groove formed on the second disk 26 does not contact with the first pin 27 fixedly mounted on the first gear 6, so that the second disk 26 can freely rotate with the first gear 6, the arc-shaped slot can be set to a proper size so that the first gear 6 and the first disk 4 can rotate freely no matter what size of culture dish is placed on the first support 5 when the first shaft 22 is in the initial position, during the period from the first disk 4 starts to rotate (the arc-shaped slot does not contact with the first pin 27) to the first disk 4 starts to contact with the first pin 27 (the arc-shaped slot does contact with the first pin 27), the first disk 4 cannot rotate to drive the first gear 6, and therefore cannot drive the first clamping support 8 and the second clamping support 9 to rotate away from the center of the first lead screw 53, when the arc-shaped slot starts to contact with the first pin 27, the first disk 4 rotates to drive the first gear 6 to rotate away from the center of the first lead screw 53 synchronously through the first pin 27 and rotate the first gear 6 to a proper position, at the moment, a worker puts the culture dish to be mixed on the first bracket 5, because the first worm wheel 24 and the first worm 23 have self-locking function, the first clamping bracket 8 and the second clamping bracket 9 have no way to rotate towards the direction close to the center of the first lead screw 53 under the action of the first clamping spring 10, after the worker puts the culture dish on the first bracket 5, the worker reversely rotates the first shaft 22, the first shaft 22 drives the first worm 23 to reversely rotate, the first worm 23 reversely rotates the first worm wheel 24, the first worm wheel 24 reversely rotates the first gear 6, the first gear 6 drives the first gear 6 to reversely rotate, the first gear 6 and the second gear 7 reversely rotate under the action of the first clamping spring 10, the second disc 26 and the first gear 6 synchronously rotate in opposite directions until the first clamping support 8 and the second clamping support 9 contact with the culture dish, at the moment, the first disc 4 rotates, but the first gear 6 cannot rotate, and in the process that the first disc 4 is separated from the contact with the first disc 4 and the first gear 6 and returns to the initial position, the first disc 4 rotates, the first gear 6 keeps static, and the first clamping support 8 and the second clamping support 9 can be opened simultaneously by a worker operating the first shaft 22, so that the operation of the worker is more convenient;

preferably, the culture dish is fixed on the first support 5 by the elastic force of the first clamping spring 10, after the culture dishes of different specifications are fixed on the first clamping support 8, the elongation of the first clamping spring 10 is different, so that the clamping force applied to the culture dish is different, if the elongation of the first clamping spring 10 is too small, the clamping force applied to the culture dish is too small, during the rotation of the first disk 4, the first clamping support 8 and the second clamping support 9 may not fix the culture dish, so that the culture dish is shaken in disorder, and finally the mixing effect of the culture dish is poor,

we rotate the third lead screw 31 installed on the first bracket 5 by driving, as shown in fig. 3, two ends of the third lead screw 31 are provided with threads with opposite turning directions, so that the second brackets 28 at two ends of the first bracket 5 can move to a position close to or away from the center of the first lead screw 53 at the same time, when the second brackets 28 move to a position close to the center of the first lead screw 53 at the same time, the second brackets 28 and the culture dish can make the first gear 6 move to a direction away from the center of the first lead screw 53, so that the elongation of the first clamping spring 10 is lengthened, and the clamping force applied to the culture dish is increased to prevent the culture dish from shaking during the rotation of the first disc 4.
