This invention discloses an integrated small embedding cassette and its tissue bottle for a pathological tissue embedding cassette sorting system, comprising a tissue bottle and an integrated small embedding cassette; the tissue bottle includes a top cover and a bottom cover, the inner wall of the top cover having a threaded structure, and the top and bottom covers being detachably connected via the threaded structure; the integrated small embedding cassette is horizontally positioned inside the tissue bottle, and the bottom cover has a sealed cavity for containing liquid; the integrated small embedding cassette includes a body and a lid, the body and lid being integrally formed. This invention, through integrated structural design, integrates the traditionally separate tissue bottle and the integrated small embedding cassette into a coaxial assembly structure, eliminating the sample transfer step, significantly reducing operational complexity, and minimizing reliance on manual labor. By setting a sealed threaded connection between the top and bottom covers, formaldehyde gas leakage from formalin solution is effectively reduced, improving biosafety.

The utility model relates to a printing roller placing rack, which comprises a base and an abutting assembly, the abutting assembly comprises a bottom plate, a first abutting block and a second abutting block, the bottom plate is arranged on the base, the first abutting block and the second abutting block are both movably connected to the bottom plate, a clamping hole for accommodating a printing roller is formed between the first abutting block and the second abutting block, and the first abutting block and the second abutting block are movably connected to the bottom plate. The base comprises a first fixing part, a second fixing part and a telescopic part, grooves are formed in the first fixing part and the second fixing part, the telescopic part telescopically slides in the grooves, and a driving assembly is arranged on the bottom plate. The size of the clamping hole is adjusted by arranging the first abutting block and the second abutting block on the bottom plate, and the first abutting block and the second abutting block do opposite movement or back-to-back movement on the bottom plate, so that the plate roller containing frame can adapt to plate rollers of different lengths and different diameters, different containing requirements are met, and the use performance of the plate roller containing frame is greatly improved.

A mechanical and electrical positioning device includes a base, a first driving unit, a movable stage, a slider, a fixing component, a limiting component, and a pin. The movable stage is movably mounted on the base. Slide grooves are provided on the front and rear sides of the movable stage, and each slide groove has multiple first locking holes. The multiple first locking holes are evenly spaced along the length of the slide groove. The slider is slidably mounted in the slide groove and has a second locking hole that is directly opposite the first locking hole. One end of the pin is installed in the first locking hole, and the other end of the pin is placed in the second locking hole. This invention provides a mechanical and electrical positioning device that solves the problem that existing mechanical and electrical positioning devices, due to their simple structure, have a single fixing method and cannot be used to fix workpieces of different sizes or shapes. Furthermore, during workpiece processing, the workpiece is prone to movement, thus affecting the processing quality.
