DETAILED DESCRIPTION

[0035] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will be a clear and complete description of the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0037] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present application is usually placed, which is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", etc. are only used for differentiation, and cannot be understood as indicating or implying relative importance.

[0039] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0040] Cell culture plates are a commonly used laboratory consumable, available in different sizes to fit various culture plates (48-well / 24-well / 12-well / 6-well). Because cell culture plates are very thin, they are inconvenient to handle, especially after culturing in the plate. They adhere to the bottom of the plate and are difficult to separate, making them very easy to break when removed. Therefore, a specific handle is needed to remove the cell culture plates.

[0041] For example, CN211999664U discloses a cell slab gripping device. Although the device can grip cell slabs, it has the following drawbacks during use. First, during use, the slabs adhere to the bottom of the culture plate, making it difficult to separate the lower surface of the slabs from the bottom of the culture plate. Direct gripping can easily damage the slabs. Second, during use, it is not easy to adjust the gripping distance, making it inconvenient to use slabs of different sizes.

[0042] To address the aforementioned technical deficiencies, the inventors have provided a cell-climbing slide holding structure and a climbing slide.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings:

[0044] Firstly, such as Figures 1-5 As shown, this utility model embodiment provides a cell smear holding structure, including: a first clamping plate 1 with a tongue-shaped end, the cross-section of which is arc-shaped, and a groove 14 formed on the tongue-shaped end; a second clamping plate 2 detachably connected to the first clamping plate 1, the end of the second clamping plate 2 being a thin sheet structure and bent toward the tongue-shaped end; both the first clamping plate 1 and the second clamping plate 2 are made of stainless steel and have a certain deformation capability; wherein, as Figure 6 As shown, when gripping the climbing plate 16 inside the culture plate 15, the first clamping plate 1 and the second clamping plate 2 are pressed so that the tongue-shaped end of the first clamping plate 1 abuts against the top edge of the climbing plate 16, and the end of the second clamping plate 2 abuts against the bottom edge of the climbing plate 16. This gripping structure allows for better adaptation of the tongue-shaped end to the shape of the climbing plate 16, reducing damage during gripping. Simultaneously, the groove 14 reduces the contact area between the tongue-shaped end and the surface of the climbing plate 16, preventing potential damage to the front of the climbing plate 16. Finally, the thin-plate structure further increases the force-bearing range of the climbing plate 16, solving the problem that direct gripping of the climbing plate 16 by existing gripping devices easily leads to damage.

[0045] Furthermore, the first clamping plate 1 includes a first connecting portion 101, a first pressing portion 102, and a first clamping portion 103. The first clamping portion 103 is a tongue-shaped end. The first pressing portion 102 is fixedly connected to the lower end of the first connecting portion 101, and the first clamping portion 103 is fixedly connected to the lower end of the first pressing portion 102. The second clamping plate 2 includes a second connecting portion 201, a second pressing portion 202, and a second clamping portion 203. The second clamping portion 203 is a thin sheet structure. The second pressing portion 202 is fixedly connected to the lower end of the second connecting portion 201, and the second clamping portion 203 is fixedly connected to the lower end of the second pressing portion 202. A buffer is also connected between the first pressing portion 102 of the first clamping plate 1 and the second pressing portion 202 of the second clamping plate 2. The buffer can buffer the pressing force and reduce the pressing force on the climbing plate. Specifically, in one embodiment, such as... Figure 1 and Figure 3 As shown, the buffer is preferably a spring 13; in another embodiment, the buffer is preferably elastic silicone. The spring or elastic silicone can absorb part of the impact force during clamping, reducing damage to the climbing sheet 16 and the cells thereon.

[0046] like Figure 3 As shown, the holding structure also includes an adjustment device, which is disposed between the first clamping plate 1 and the second clamping plate 2. The adjustment device is used to adjust the relative position between the first clamping plate 1 and the second clamping plate 2. Specifically, a connecting groove 3 is provided at one end where the first clamping plate 1 and the second clamping plate 2 are connected. The connecting groove 3 is a long strip structure. The adjustment device includes a first adjustment component, which is disposed in the connecting groove 3 and is used to adjust the relative position between the first clamping plate 1 and the second clamping plate 2. When the first adjustment component rotates clockwise, the first clamping plate 1 and the second clamping plate 2 move closer to each other and abut against each other. When the first adjustment component rotates counterclockwise, the first clamping plate 1 and the second clamping plate 2 move further apart from each other. In this embodiment, the first adjustment component includes a limiting block 4, a first gasket 5, and a connecting pin 6. One end of the connecting pin 6 is disposed on the second clamping plate 2 through a connecting groove 3, and the other end is screwed to the limiting block 4. The first gasket 5 is disposed at the end of the limiting block 4 near the first clamping plate 1. The first adjustment component is used to adjust the vertical position of the first connecting part 101 and the second connecting part 201. By rotating the limiting block 4 clockwise, the first gasket 5 is pressed against the left end face of the first connecting part 101, thereby limiting the connection between the first connecting part 101 and the second connecting part 201, thereby adjusting the distance between the lower end of the second clamping part 203 and the lower end of the first clamping part 103.

[0047] The adjusting device further comprises a second adjusting assembly, a first connecting hole 11 is formed in the middle part of the first clamping plate 1, a second connecting hole 12 is formed in the middle part of the second clamping plate 2, the first connecting hole 11 corresponds to the second connecting hole 12, and the second adjusting assembly is arranged between the first connecting hole 11 and the second connecting hole 12 and used for adjusting the distance between the first clamping plate 1 and the second clamping plate 2.

[0048] In application, the up-down positions of the first connecting part 101 and the second connecting part 201 are adjusted through the limiting block 4, the first gasket 5 is pressed against the left end face of the first connecting part 101 by rotating the limiting block 4 clockwise, and then the first connecting part 101 and the second connecting part 201 are limitedly connected, so that the distance between the lower end of the second clamping part 203 and the lower end of the first clamping part 103 is adjusted; then, the first pressing part 102 and the second pressing part 202 are pinched, and the first clamping part 103 and the second clamping part 203 are used to clamp the climbing sheet 16, since the cross section of the first clamping part 103 is arranged in an arc shape and the groove 14 is formed in the first clamping part 103, the first clamping part 103 can reduce the contact area with the front surface of the climbing sheet 16 when the climbing sheet 16 is fixed by cooperating with the second clamping part 203, so that the damage to the cells on the front surface of the climbing sheet 16 is reduced, and meanwhile, the second clamping part 203 is used to extend into the space between the climbing sheet 16 and the culture plate 15, so that the lower surface of the climbing sheet 16 is separated from the culture plate 15.

[0049] In the second aspect, the embodiment provides a climbing sheet, which comprises a climbing sheet body and is held by the cell climbing sheet holding structure as described above.

[0050] Finally, it should be noted that: the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit the protection scope thereof, although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that: after reading the utility model, the skilled in the art can still make various changes, modifications or equivalent replacements to the specific implementation manner of the invention, but these changes, modifications or equivalent replacements are all within the protection scope of the claims of the invention to be approved.
