[0034] like Figure 3-Figure 5As shown, when the culture dish needs to be installed on the top of the positioning plate body 3, the bidirectional threaded rod 8 arranged inside the positioning plate body 3 is manually rotated, so that during the rotation, the bevel gear group 10 on the outer wall of the middle part drives the guide threaded rods 9 meshingly connected at the front and rear sides to rotate, and then the bidirectional threaded rod 8 and the positioning guide seat 11 threadedly connected to the outer wall of the guide threaded rod 9 are driven to slide synchronously outward, so that the positioning guide seat 11 is in the maximum range, thereby facilitating the subsequent installation of the culture dish;
[0035] Furthermore, the culture dish is placed in the middle of the top surface of the positioning plate body 3, and then the above steps are repeated in reverse, so that the rotating bidirectional threaded rod 8 and the guide threaded rod 9 drive the positioning guide seat 11 threadedly connected to the outer wall to slide inward, and the positioning guide seat 11 set at equal angles contacts the outer wall of the culture dish, so as to limit the position of the culture dish and prevent it from being displaced and flipped during the cleaning and rinsing process.
