In the example of fig. 6 and 7, the two locking members 105 are arranged at 90 ° intervals around a longitudinal center line where the trigger member 104 is disposed, the trigger member 104 includes two trigger portions 114 and two insertion portions 113 arranged at 90 ° intervals around the longitudinal center line, the two trigger portions 114 and the two insertion portions 113 respectively correspond to the pressed ends 110 of the two lever members 103 in the longitudinal direction, and the two insertion portions 113 respectively correspond to the two locking members 105 in the longitudinal direction, so that the trigger member 104 inserts the two locking members 105 while driving the two lever members 103 to pivot synchronously in the direction of gripping the light source control box 300, and the two locking members 105 lock the trigger member 104 while the two lever members 103 grip the light source control box 300, thereby synchronously spacing the two lever members 103.

In one embodiment, as shown in fig. 6 and 7, each lever assembly 103 further includes a limiting frame 124, and in a state that the two lever assemblies 103 jointly clamp the light source control box 300, the limiting frames 124 of the two lever assemblies 103 jointly limit the position of the cell culture plate 200 in the lateral direction, so that the cell culture plate 200 and the light source control box 300 are aligned in the longitudinal direction.

In the past when installing cell culture plate 200, the rib of cell culture plate 200 below is difficult to accurately insert in the draw-in groove of light source control box 300 top, leads to the unable inseparable laminating of up end of the interior spotlight board of cell culture plate 200 of light source control box 300 after installing, leads to the light source between the micropore to interfere with each other, and this embodiment is through setting up spacing 124, under the state of lever assembly 103 chucking light source control box 300, adopt clamping jaw 401 of arm 400 to place cell culture plate 200 between two spacing 124, two spacing 124 play the effect of rectifying to cell culture plate 200's position, make cell culture plate 200 can closely laminate with the spotlight board of below, avoid the problem emergence of light source interference between the micropore.

When the cell culture plate 200 is aligned with the light source control box 300, the side surfaces of the cell culture plate 200 are attached to the inner side surfaces of the two limiting frames 124, in this case, if the clamping jaw 401 of the mechanical arm 400 presses down the cell culture plate 200, the placing table 102 will be driven to move downward, when the placing table 102 contacts the trigger piece 104, if the placing table is pressed down continuously, the pressed end 110 of the lever assembly 103 will have a tendency to rotate downward, but because the limiting frames 124 of the lever assembly 103 are attached to the cell culture plate 200, the limiting frames 124 and the vertical arms 109 will be blocked by the cell culture plate 200 and cannot rotate along with the pressed end 110.

To avoid the stop 124 blocking downward rotation of the pressed end 110, in one embodiment, as shown in fig. 11 and 12, the inventors design the upright arm 109 and the horizontal arm 108 of the lever assembly 103 to be pivotally connected to allow relative rotation therebetween, and a tension spring 125 is connected between the horizontal arm 108 and the upright arm 109.
