[0049] The above-mentioned air holes 154 are used to cooperate with the elastic air cushion 152. When the elastic air cushion 152 is subjected to the pressure of the culture dish 2, the gas inside it will be discharged outward through the air holes 154, so that the elastic air cushion 152 will shrink accordingly.

[0050] See also Figure 7The movable turntable 16 includes an interface 161, a shell 162, a card ball 163, a limit seat 164, and a contact spring 165.

[0052] The above-mentioned locking ball 163 is used to cooperate with the contact spring piece 165. When the shell 132 is connected to the interface 161 and rotates, the limiting recess 131 and the top support spring piece 133 will be directly squeezed out with the locking ball 163 and the contact spring piece 165. The contact spring piece 165 is made of elastic material and has good elasticity. When the contact spring piece 165 is in contact with the top support spring piece 133, it will kiss the top support spring piece 133 in an arc shape.

[0053] The working principle of the above technical solution is described as follows:

[0054] When the present invention is in use, the staff will vertically place the culture dish 2 on the connecting groove 151, and the bottom of the culture dish 2 will directly contact the contact pad 153, which can effectively protect the bottom of the culture dish 2. The staff will press the culture dish 2 downward, and the contact pad 153 will be transmitted to the elastic air cushion 152 after receiving the pressure of the culture dish 2. After the elastic air cushion 152 is subjected to the pressure of the culture dish 2, the gas inside will be discharged outward through multiple air holes 154, so that the elastic air cushion 152 will shrink accordingly. The shrunk elastic air cushion 152 will wrap and attach to the outside of the culture dish 2, effectively limiting the position of the culture dish 2. The triangular frame 4 is sleeved on the positioning rod 3, and the positioning rod 3 is vertical to the tea set. Inserted on the socket 14, the triangular frame 4 is fixedly connected with the ferrule ring 5, and the triangular frame 4 drives the ferrule ring 5 to move downward under the action of the positioning rod 3, so that the ferrule ring 5 can be vertically sleeved on the culture dish 2, and effectively cooperate with the connecting groove 151 to limit the position of the culture dish 2, so as to prevent the culture dish 2 from shifting, so that the staff can stably observe the microorganisms inside the culture dish 2. After observing a culture dish, the staff is driven to rotate the mounting seat 12, and the mounting seat 12 is fixedly connected with the shell 132 through the docking piece 11, so that after the mounting seat 12 is subjected to the rotation force of manual rotation by the staff, it will drive the docking piece 11 and the shell 132 to rotate in the same direction;

[0055] The shell 132 will drive the limiting recess 131 and the supporting spring 133 to rotate together. The card seat B4 and the cavity C3 form a wavy structure, which can drive the mounting seat 12 to rotate at a uniform and stable speed, and the shell 132 is vertically clamped on the interface 161. During the rotation of the shell 132 on the interface 161, the lower slide B3 and the upper slide C4 are in contact with the card ball 163 and the contact spring 165. When the lower slide B3 is in contact with the card ball 163, the position of the card ball 163 is positioned and limited by the outer shell 162 and the limiting seat 164 to ensure that the card ball 163 will not be misplaced. The shell 132 can stably rotate on the interface 161, and the card ball 163 will be connected. The top is pressed on the lower slide B3. After being pressed, the lower slide B3 will be concave and shrink to squeeze the stacking member B2. After being pressed, the stacking member B2 will shrink inward and overlap each other. After the two stacking members B2 shrink at the same time, the elastic member B1 will shrink inward under the action of the stacking member B2, so that the lower slide B3 and the card ball 163 can be stably connected together. When the housing 132 is continuously rotating, the lower slide B3 will slide off the card ball 163. After the lower slide B3 is not squeezed by the card ball 163, the elastic member B1 will generate a rebound force to push outward when it is not pressed. The stacking member B2 will be opened outward due to the rebound effect of the elastic member B1, effectively pushing the lower slide B3 outward.

[0056] After the lower slide plate B3 slides out of the ball 163 and moves to the contact spring 165, the upper slide plate C4 will be pressed by the ball 163 when in contact with the ball 163, and the top pressure will be transmitted to the cavity C3. The opening and closing parts C1 on both sides of the cavity C3 will drive the connecting plate C2 to shrink along with the movement of the cavity C3, and the connecting plate C2 will disperse and transmit the pressure to the corrugated spring member C5. The corrugated spring member C5 will shrink inward after being compressed. The inside of the triangular support C6 is in a tight state and is not easy to deform after being compressed, so that the cavity C3 and the ball 163 will be effectively supported, so that a relative counter pressure will be generated between the cavity C3 and the ball 163 and connected together. When the shell 132 continues to rotate, the upper slide plate C4 will slide out from the ball 163 and move to the contact spring member 165. The corrugated spring member C5 will instantly generate a rebound force when not under force, so that the two connecting plates C2 will be outward. The connecting plate C2 drives the opening and closing member C1 to open outwards, and the cavity C3 opens outwards under the action of the opening and closing member C1 and the connecting plate C2 to push the upper slide C4 outwards. After being pushed out, the upper slide C4 will contact the contact spring 165. After the contact spring 165 is subjected to the pushing force of the upper slide C4, it will bend into an arc shape and kiss the upper slide C4 together. The mounting seat 12 is driven to rotate on the interface 161 through the socket B4 and the cavity C3 in cooperation with the shell 132, and the base 17 is fixedly installed on the workbench, so that the shell 132 can be stably rotated inside the shell 162, and the position of the culture dish 2 on the mounting seat 12 can be rotated and adjusted. The staff can quickly and effectively observe and compare the culture dishes 2 on the mounting seat 12 one by one, to ensure that the culture dishes are not easily confused during observation and replacement, and effectively improve the staff's observation efficiency of microorganisms.

[0057] In summary, the present invention adopts the combination of an adjustment device, a culture dish, a positioning rod, a triangular frame, and a clamping ring to form a new microbial fermentation culture dish. The culture dish is installed on the slot, and the clamping ring is sleeved on the culture dish, which effectively cooperates with the slot to limit the position of the culture dish. When the staff adjusts the position of the culture dish, they will apply force to the mounting seat, and the rotating adjustment member will receive the rotational force transmitted by the mounting seat and rotate on the movable turntable, effectively adjusting the position of the culture dish, so that the staff can quickly and effectively observe the microorganisms on multiple culture dishes one by one, making it less likely that the culture dishes will be confused.
