Abstract: An automatic biological sample library, includes a frame, an upper computer, a control system, a liquid nitrogen tank, an insulated chamber, a transfer container, a rotary-disk rotating module, a basket lifting module, a tray shoveling module, a tube picking module and a transfer module. The rotary-disk rotating module, the basket lifting module, the tray shoveling module, the tube picking module and the transfer module are electrically connected to the control system.

Abstract: Provided a vitrification freezing carrier includes a tube body of a hollow structure with an opened end provided with a matching part, a tube cap provided with a covering part of a hollow structure with one end closed and matching the matching part and provided with an extending part connected to the covering part, a carrying rod arranged on a side, facing an interior of the tube body, of the covering part and capable of extending into the tube body, and an auxiliary sampling mechanism including a carrier body provided with a locking part configured to be matched with the covering part to drive the covering part to move and an elastic reset assembly arranged on the carrier body and including a driving part and an elastic part driven by the driving part and capable of being selectively connected to the extending part in a matched manner.

Abstract: This invention provides a sunshade and a sunshade base thereof. The sunshade base, configured to be connected with a sunshade rod to support a sunshade top, the sunshade includes: a support, an upper side of the support is provided with a connection member for being connected with the sunshade rod; a moving assembly, rolling or sliding to drive the support to move; and a counterweight, the support has a counterweight area for supporting the counterweight. When the sunshade needs to be moved, it only needs to drive the moving assembly to roll or slide, thereby driving the support and the whole sunshade to move. Compared with the prior art in which several people is required to work together to move the sunshade, this invention greatly reduces the labor intensity of moving the sunshade, thereby making the moving of the sunshade more time-saving and labor-saving.
