Still further, still include vertical shrink-proof mechanism, vertical shrink-proof structure at least one vertical support rod, vertical support rod is located the inside of absorption chamber 6.4, its bottom is connected in the stereoplasm structure of absorption chamber 6.4 bottom, the back of top laminating load-bearing groove 6.1, the effect that so sets up lies in, when load-bearing groove 6.1 is by the jack-up, it breaks away from vertical support rod, the jack-up of load-bearing groove 6.1 is not influenced this moment, and the recovery in-process, if extrusion amplitude is too big in earlier stage, probably load-bearing groove 6.1 can take place to inboard deformation and the extrusion carries the broken piece to lead to its breakage this moment, perhaps can't maintain the horizontality and lead to blood flow, it makes it maintain the not shrink of horizontality to support the cell wall board of load-bearing groove 6.1 through vertical support rod.
Still further, as shown in fig. 5, the top surface of the bearing mechanism 6 includes a bearing groove 6.1 in the central area and an arc-shaped deformation portion 6.7 surrounding the bearing groove 6.1, when the squeezing portion 6.5 is not squeezed, the arc-shaped deformation portion 6.7 bends downward, and when the squeezing portion 6.5 is squeezed to a certain extent, the arc-shaped deformation portion 6.7 bends upward as a whole, at this time, as shown in fig. 7, the bearing groove 6.1 is located at the highest position, and the arc-shaped deformation portion 6.7 makes the deformation of the top surface regular and can make the bearing groove 6.1 located at the highest point, and at the highest point, the top surface is still in a horizontal state.
In the embodiments of the present invention, after the glass slide 7 is adsorbed on the carrying groove 6.1, the pressure in the adsorption chamber 6.4 is negative relative to the external environment, but after vacuum pumping, the external pressure is sharply reduced, and at this time, the pressure in the adsorption chamber 6.4 becomes positive, and at this time, the pressure in the adsorption chamber 6.4 may lift up the glass slide 7 and allow the gas to flow away therefrom, further, the adsorption chamber 6.4 communicates with the outside through a channel, and an automatic valve mechanism is disposed in the channel, as shown in fig. 6 and 8, the automatic valve mechanism includes a hard plate 13 and an elastic plate 14, the hard plate 13 and the elastic plate 14 are respectively connected to opposite sides in the channel, the ends of the two are butted to seal the channel, and the end of the elastic plate 14 is butted to the outside of the end of the hard plate 13, when the squeezing portion 6.5 is not squeezed, as shown in fig. 6, the elastic plate 14 and the hard plate 13 are butted to close the channel, and when vacuum pumping, the inner side pressure is small, the inner side pressure is greatly deformed, and the hard plate 13 is separated from the inside of the adsorption chamber 6.4, and the gas escape from the adsorption chamber 7 is not adversely affected, as shown in fig. 6.8. Moreover, because a large amount of gas escapes, when the outside environment is recovered from vacuum to normal, the inside of the adsorption cavity 6.4 is substantially vacuum, and the vertical anti-shrinkage mechanism well supports the bearing groove 6.1 to prevent the inside from collapsing and deforming.
Furthermore, the abutting portion of the hard board 13 is provided with an expanding portion 13.1, and the expanding portion 13.1 abuts against the elastic board 14, so that the contact area between the hard board and the elastic board 14 is increased, and the sealing effect is improved.
As an alternative, the automatic valve mechanism comprises two elastic plates 14 which are butted together, and this has the advantage that when the outside environment is restored to normal by vacuum, the elastic plates 14 can deform inwardly so that the gas re-enters the adsorption chamber 6.4, and the negative pressure reached in the adsorption chamber 6.4 is actually the deformation pressure of the elastic plates 14.
In another embodiment of the present invention, a blood film forming mechanism 8 is further disposed in the box 3, the blood film forming mechanism 8 is configured to form a blood film from a blood drop on the slide 7, and as is common, the blood film forming mechanism 8 includes a push piece, and the push piece moves from one side to the other side of the slide 7 to form a blood film from the blood drop, and optionally, the blood film forming mechanism 8 may be a smearing mechanism or a similar structure in the background art.
