Fig. 3 illustrates a schematic structural view of a magnet holder 23a according to some embodiments of the present disclosure. Fig. 4 illustrates a structural perspective view of a magnet holder 23a according to some embodiments of the present disclosure.

As shown in fig. 3 and 4, in some embodiments of the present disclosure, the brackets (e.g., bracket 20a, bracket 20 b) may also include a magnet holder (e.g., magnet holder 23a, magnet holder 23 b). The magnet holder (e.g., magnet holder 23a, magnet holder 23 b) can be used to carry a driving magnet (e.g., driving magnet 30a, driving magnet 30 b).

In order to clearly illustrate the structure of the magnet holder, in some embodiments of the present disclosure, the structure of the magnet holder is illustrated by taking the magnet holder 23a as an example.

As shown in fig. 3 and 4, the magnet holder 23a may include mounting holes (e.g., mounting holes 231a, 231b, 231c, 231 d). The elastic means (e.g., elastic means 22a, elastic means 22b, elastic means 22c, elastic means 22 d) may include springs (e.g., springs 221a, 221b, 221c, 221 d), support columns (e.g., support columns 222a, 222b, 222c, 222 d). Springs (e.g., spring 221a, spring 221b, spring 221c, spring 221 d) are disposed within the mounting holes (e.g., mounting hole 231a, mounting hole 231b, mounting hole 231c, mounting hole 231 d). The support columns (e.g., support column 222a, support column 222b, support column 222c, support column 222 d) are in abutment with springs (e.g., springs 221a, 221b, 221c, 221 d). The support columns (e.g., support column 222a, support column 222b, support column 222c, support column 222 d) are at least partially disposed within the mounting holes (e.g., mounting holes 231a, 231b, 231c, 231 d) and are connected at the top to the sliders (e.g., sliders 21a, 21b, 21c, 21 d).

In some embodiments of the present disclosure, the mounting holes (e.g., mounting holes 231a, 231b, 231c, 231 d) may include laterally disposed stop holes (e.g., stop holes 2311a (not visible), stop holes 2311b (not visible), stop holes 2311c, 2311 d).

The base 10 may be a rectangular plate, and at least one adjustment slide rail (e.g., adjustment slide rail 40a, adjustment slide rail 40 b) and at least one adjustment slide block (e.g., adjustment slide block 50a, adjustment slide block 50 b) are disposed on the base 10. The adjustment slide rails (e.g., adjustment slide rail 40a, adjustment slide rail 40 b) are provided at two short sides of the base 10, respectively, and the adjustment slider (e.g., adjustment slider 50a, adjustment slider 50 b) is provided on the adjustment slide rails (e.g., adjustment slide rail 40a, adjustment slide rail 40 b). The brackets (e.g., brackets 20a, 20 b) are disposed on the adjusting sliders (e.g., adjusting sliders 50a, 50 b) and can move back and forth along the adjusting slide rails (e.g., adjusting slide rails 40a, 40 b) under the driving of the adjusting sliders (e.g., adjusting sliders 50a, 50 b), thereby adjusting the position of the driving magnet.

In some embodiments of the present disclosure, the vacuum magnetic drive car 100 may also include a slide bar (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d). The slide bars (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d) are adjustably slidably coupled to adjustment holes (not shown) of the brackets (e.g., bracket 20a, bracket 20 b), and one end (e.g., the upper end as shown) is fixedly coupled to the magnet holder (e.g., magnet holder 23a, magnet holder 23 b) and can be used to adjust the distance of the drive magnets (e.g., drive magnet 30a, drive magnet 30 b) from the vacuum cart 200.

Those skilled in the art will appreciate that while the slide bars 80a, 80b are shown mounted on the support 20a and the slide bars 80c, 80d are shown mounted on the support 20b in FIGS. 1 and 2, the slide bars may be in a one-to-one correspondence with the supports.

In some embodiments of the present disclosure, the slide bars (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d) may include threads (not shown) that couple with adjustment hole threads (not shown) of the brackets (e.g., bracket 20a, bracket 20 b) that can be used to adjust the distance of the drive magnets (e.g., drive magnets 30a, drive magnets 30 b) from the vacuum carrier 200 by threadably adjusting the magnet holders (e.g., magnet holders 23a, magnet holders 23 b).

In some embodiments of the present disclosure, vacuum magnetic drive car 100 may also include mounts (e.g., mount 60a, mount 60 b). The mounting seats (e.g., mounting seat 60a, mounting seat 60 b) are fixedly connected to the other end (e.g., lower end as shown) of the slide bar (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d).

In some embodiments of the present disclosure, the vacuum magnetic drive car 100 may further include a fixation nut (e.g., fixation nut 70a, fixation nut 70b, fixation nut 70c, fixation nut 70 d).

For example, the slide bars (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d) slide downward, driving the mounts (e.g., mount 60a, mount 60 b) downward, increasing the distance between the driving magnet and the vacuum specimen carriage, thereby disengaging the vacuum specimen carriage from the vacuum magnetic drive carriage 100. The slide bars (e.g., slide bar 80a, slide bar 80b, slide bar 80c, slide bar 80 d) slide upward, driving the mounting blocks (e.g., mounting block 60a, mounting block 60 b) to move upward, and after turning the fixing nuts (e.g., fixing nut 70a, fixing nut 70b, fixing nut 70c, fixing nut 70 d) in place, fixing the mounting blocks (e.g., mounting block 60a, mounting block 60 b) in place, reducing the distance between the transmission magnet and the vacuum sample carrier, thereby coupling the vacuum sample carrier with the vacuum magnetic drive car 100, and being driven by the vacuum magnetic drive car 100.
