[0029] The box cover 2 is composed of a U-shaped frame 21 and a sealing plate 22. The sealing plate 22 is installed in the U-shaped frame 21 and can be adjusted in the length direction of the box body 1. One side of the sealing plate 22 is provided with a taking and placing opening 221 penetrating up and down for taking and placing the hair follicles. When the sealing plate 22 slides left and right along the U-shaped frame 21, the position of the taking and placing opening 221 on the sealing plate 22 changes synchronously. When the taking and placing opening 221 moves to align with a certain storage compartment 01, the hair follicles in the storage compartment 01 can be taken and placed. The remaining storage compartments 01 are covered by the remaining part of the sealing plate 22, so that the excessive loss of cold in the remaining storage compartments 01 is reduced. In addition, when the sealing plate 22 is retreated to the limit position in the U-shaped frame 21, the taking and placing opening 221 is shielded and plugged by the top surface of the box body 1. At this time, the taking and placing opening 221 is not aligned with any storage compartment 01, and the sealing plate 22 covers and plugs the top of all the storage compartments 01, so that the effective heat preservation is provided.
