The end of the second rack 3265 close to the center of the base 1 is bent toward the central axis of the gear column 327 and fixedly connected to a movable rod 3264. The movable rod 3264 slides through a side wall of the placement seat 3 close to the center of the base 1. The movable rod 3264 is fixedly connected to a limiting plate 3263.

[0043] During specific operation, when the placement seat 3 changes its position, the roller 3261 rolls along the variable diameter wheel 329. When it is at the scanning position, the diameter of the variable diameter wheel 329 becomes larger, which will cause the movable rod 3264 to shrink into the placement seat 3, and the spring three 3262 will be stretched.

Similarly, when it is at the loading point and the unloading point, the automatic return control of the spring three 3262 controls the movable rod 3264 to extend, and the gear column 327 is reversed. The sliding rod 3231 and the spring two 3232 cooperate to make the locking bar 321 elastic to avoid hard squeezing of the slice.

[0044] See also Figure 5 The loading component 42 includes a push plate 422 corresponding to any slice position in the slice arrangement frame 2 at the loading point, the push plate 422 is located on the side of the slice arrangement frame 2 at the loading point away from the center of the base 1, the push plate 422 is fixedly connected to a push rod 421 on the side away from the center of the base 1, the push rod 421 is fixedly connected to one end away from the center of the base 1 with two bending frames 423, the two bending frames 423 are fixedly connected to one end away from the push rod with a mounting strip 424 radially parallel to the base 1, and the mounting strip 424 is slidably connected to the outer wall of the guide frame 41 through a fixed block.

The pin shaft of any linkage gear 446 is also fixedly connected to the output end of the control motor 442. The control motor 442 is fixedly connected to the lower side of the mounting plate two 443.

[0047] During specific operation, the motor 442 is controlled to drive any one of the linkage gears 446 to rotate, so that multiple linkage gears 446 rotate synchronously, the linkage gear 446 close to the rack four 445 drives the rack four 445 to move, and the linkage gear 446 close to the rack three 441 drives the rack three 441 to move. An odd number of linkage gears 446 is set, which can better conform to the actual movement direction of the rack three 441 and the rack four 445.

[0049] During specific operation, the slices are elastically clamped by the elasticity of the spring 221, so that the slices can slide freely.

[0050] See also Figure 1 , Figure 5 and Figure 6 The step-lifting assembly 21 includes a guide frame 41 corresponding to the loading point and the unloading point and fixedly connected to the base 1. The slice arrangement frame 2 is slidably and limit-connected in the guide frame 41. The two adjacent side walls of the two guide frames 41 are provided with movable grooves 213. A connecting arc frame 211 is slidably connected between the two movable grooves 213.

[0051] During specific operation, the electric push rod 212 controls the connection arc frame 211 to rise, and the connection arc frame 211 drives the support plate 214 to continuously raise the slice arrangement frame 2, so that each layer in the slice arrangement frame 2 corresponds to the loading and unloading height one by one.

[0052] When in use: S1: Arrange the slices to be scanned in order and place them on the slice arrangement rack 2, and elastically clamp the slices through the elasticity of spring 1 221. The slice arrangement rack 2 can be set to multiple groups, half of which is used to load the slices to be scanned, and the other plate is not filled with slices. One of the slice arrangement racks 2 with installed slices is placed in the guide rack 41 at the loading point, and at the same time, a slice arrangement rack 2 without slices is placed in the guide rack 41 at the unloading point.

[0053] S2: The electric push rod 212 controls the connection arc frame 211 to rise, and the connection arc frame 211 drives the support plate 214 to lift the slice arrangement frame 2, so that the first layer in the slice arrangement frame 2 corresponds to the loading and unloading height.

[0054] S3: By controlling the motor 442 to drive any one of the linkage gears 446 to rotate, multiple linkage gears 446 can rotate synchronously, the linkage gear 446 close to the rack four 445 drives the rack four 445 to move, and the linkage gear 446 close to the rack three 441 drives the rack three 441 to move, and the rack three 441 drives the mounting bar two 432 to control the height limit plate 433 to drive the push plate two 434 to push the slices on the unloading point placement seat 3 into the slice arrangement rack 2 at the unloading point, and the rack four 445 drives the mounting bar one 424 to control the two crooked racks two 423 to drive the push rod 421 and the push plate two 434 to move to push the slices in the slice arrangement rack 2 at the loading point to the placement seat 3 at the loading point.

[0055] S4: S3 is performed twice each time, that is, the placement seat 3 rotates 180° to perform a scan. When the placement seat 3 changes its position, the roller 3261 rolls along the diameter-changing wheel 329. When it is at the scanning position, the diameter of the diameter-changing wheel 329 increases, which will cause the movable rod 3264 to shrink into the placement seat 3, and the spring three 3262 will be stretched. The shrinkage of the movable rod 3264 will drive the gear column 327 to rotate, and the rotation of the gear column 327 controls the two racks 1 325 to move along the guide rod 324. The rack 1 325 drives the locking bar 321 through the two crooked frames 1 322 to lock the position of the slice at the scanning point to ensure the uniformity of the slice scanning position. Similarly, when it is at the loading point and the unloading point, the automatic return of the spring three 3262 controls the movable rod 3264 to extend and reverse the gear column 327.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
