Brain tissue freezing embedding box

The utility model discloses a brain tissue freezing and embedding box, and provides the following scheme aiming at the problems that the existing square box has a quick tissue package, is difficult to take out, is easy to cause tissue damage, cannot effectively fix and adjust the tissue orientation, has a liquid nitrogen frostbite risk and the like, the brain tissue freezing and embedding box comprises a vertical rod and four U-shaped square boxes, and the bottom of the vertical rod is fixedly connected with a cross-shaped plate; the four U-shaped square boxes are connected with the cross-shaped plate in a clamped mode through clamping assemblies. According to the brain tissue freezing device, brain tissue can be blocked through the two side plates, meanwhile, the stability of connection between the side plates and the U-shaped square boxes is guaranteed through the first magnets and the second magnets, the application range of the device can be widened through the arrangement of the U-shaped square boxes, an
