A fixing seat 6 is fixedly installed on the inner side of the top wall of the placement box 3 on the left and right sides of the circular hole 5 by bolts, and a guide rod 7 extending left and right along the radial direction of the circular hole 5 is slidably installed on the fixing seat 6, a mounting plate 8 is fixedly installed on the inner end of the guide rod 7 by bolts, and a connecting seat 9 is fixedly installed on the inner side of the mounting plate 8 by bolts, and an arc-shaped plate 10 for clamping the culture dish 4 is integrally formed at the end of the connecting seat 9 away from the mounting plate 8, and a curved plate 10 for clamping the culture dish 4 is provided between the fixing seat 6 and the mounting plate 8, a first spring 11 is sleeved on the guide rod 7 between the guide rods 7, and a baffle 12 is fixedly installed on the outer end of the guide rod 7 by bolts. The baffle 12 can prevent the guide rod 7 from escaping from the fixing seat 6 inward; an electric cylinder 13 with a piston rod extending toward the circular hole 5 is also installed on the fixing seat 6, and the cylinder body of the electric cylinder 13 is fixedly installed on the fixing seat 6 by bolts. The piston rod of the electric cylinder 13 is arranged parallel to the guide rod 7, and a sliding hole 14 through which the piston rod of the electric cylinder 13 passes is provided on the mounting plate 8, and a baffle 15 located on the inner side of the mounting plate 8 is fixedly installed on the piston rod of the electric cylinder 13 by bolts.

[0022] Specifically, when placing the culture dish 4, the electric cylinder 13 is first contracted to drive the baffle 15 to move outward to the side away from the circular hole 5. When the baffle 15 contacts the mounting plate 8, the electric cylinder 13 contracts and drives the mounting plate 8 to move outward through the baffle 15. The mounting plate 8 drives the guide rod 7 to slide outward and compresses the first spring 11. At the same time, the mounting plate 8 drives the connecting seat 9 and the arc plate 10 to move outward, so that the distance between the two arc plates 10 increases; the culture dish 4 is placed in the circular hole 5, and then the electric cylinder 13 is extended to drive the baffle 15 to move inward to the side close to the circular hole 5, and then the first spring 11 in the compressed state is extended and pushes the mounting plate 8 to move inward, and the mounting plate 8 drives the connecting seat 9 and the arc plate 10 to move inward, so that the two arc plates 10 elastically clamp the culture dish 4. Figure 2 and Figure 3 As shown, the stability of the placement of the culture dish 4 is improved, and the culture dish 4 is prevented from being separated from the round hole 5 and overturned when the culture incubator is being transported or hit.

[0023] A support plate 16 for holding the culture dish 4 is provided in the placement box 3, and a vertically extending sliding rod 17 is fixedly installed at the bottom of the support plate 16. Two sliding rods 17 are arranged side by side on the left and right, and the upper ends of the sliding rods 17 are screwed into the bottom of the support plate 16. A sleeve 18 corresponding to the sliding rod 17 is fixedly installed on the inner side of the bottom wall of the placement box 3. The sleeve 18 extends vertically, and the lower end of the sleeve 18 is fixedly installed on the bottom wall of the placement box 3 by bolts. A through hole 19 for the sliding rod 17 to pass through is provided on the top wall of the sleeve 18, and a stopper 20 located in the sleeve 18 is integrally formed at the lower end of the sliding rod 17. A second spring 21 is sleeved on the sliding rod 17 located between the top wall of the sleeve 18 and the stopper 20, and a linkage mechanism for driving the support plate 16 to rise is connected between the connecting seat 9 and the support plate 16.

[0024] The linkage mechanism includes an inclined rod 22 connected between the connecting seat 9 and the supporting plate 16. When the connecting seat 9 moves outward, the supporting plate 16 is driven to rise through the inclined rod 22.

[0025] Specifically, two oblique rods 22 are arranged opposite to each other on the left and right sides, and two connecting plates 23 are welded opposite to each other on the left and right sides of the support plate 16. The lower end of the oblique rod 22 is hinged between the corresponding two connecting plates 23 through a first pin shaft 24 extending front and back; a second pin shaft 25 extending front and back is fixedly installed on the upper end of the oblique rod 22, and a mounting groove 26 is arranged at the bottom of the connecting seat 9. The mounting groove 26 is connected inwardly to the inner side of the arc-shaped plate 10, and waist holes 27 matching the second pin shaft 25 are arranged on the front and rear side walls of the mounting groove 26. The length direction of the waist hole 27 extends left and right along the length direction of the guide rod 7, and the waist hole 27 passes through the connecting seat 9 front and back. The front and rear ends of the second pin shaft 25 are respectively movably installed in the corresponding waist holes 27.

[0026] Specifically, when placing the culture dish 4, the electric cylinder 13 is first contracted to drive the connecting seat 9 and the curved plate 10 to move outward, so that the distance between the two curved plates 10 is increased. When the connecting seat 9 moves outward until the inner end of the waist hole 27 contacts the second pin 25, the connecting seat 9 moves outward and drives the second pin 25 to move outward synchronously, and then the connecting seat 9 pulls the support plate 16 up through the inclined rod 22 and compresses the second spring 21; the culture dish 4 is placed on the top of the support plate 16 through the circular hole 5, and then the electric cylinder 13 is extended, and the first spring 11 drives the connecting seat 9 and the curved plate 10 to move inward. At the same time, the second spring 21 is extended and drives the support plate 16 to descend, and the support plate 16 drives the culture dish 4 to descend. When the support plate 16 descends to contact the top of the sleeve 18, the connecting seat 9 and the curved plate 10 continue to move inward until the two curved plates 10 elastically clamp the culture dish 4.

[0027] Or when the culture dish 4 needs to be taken out, the electric cylinder 13 is contracted to drive the connecting seat 9 and the arc plate 10 to move outward, so that the distance between the two arc plates 10 is increased, and the two arc plates 10 first release the culture dish 4; the connecting seat 9 and the arc plate 10 continue to move outward, and when the connecting seat 9 moves outward until the inner end of the waist hole 27 hits the second pin 25, the connecting seat 9 moves outward and drives the supporting plate 16 to rise, and the supporting plate 16 drives the culture dish 4 to rise. Figure 4 As shown, it is convenient to take the culture dish 4 out of the circular hole 5.
