[0032] The clamping assembly 3 is arranged in the through hole 11 of the top surface of the box body 1, so as to enhance the stability of the EP tube and prevent the EP tube from being tilted or leaking.

[0033] The locking assembly 4 is arranged on the side wall of the box cover 2, so as to realize automatic buckling and fixing of the box body 1.

[0034] Specifically, in the embodiment, the box body 1 is arranged in a rectangular structure, and the inner portion thereof is hollow, so as to store a cold medium such as an ice bag, thereby realizing low-temperature storage of the EP tube on the box body 1 and improving the protection effect.

[0035] The fixing groove 12 is further formed on the inner side wall of the through hole 11 and extends to both sides.

[0036] The clamping assembly 3 includes a clamping plate 31 arranged in the fixing groove 12, one end of the clamping plate 31 extends to the center of the through hole 11 and is connected with an arc-shaped plate 32, the end surface of the arc-shaped plate 32 is provided with an elastic pad, the elastic pad can be a silica gel pad, a rubber pad or a medical cotton, the other surface of the arc-shaped plate 32 extends to the inside of the fixing groove 12 and is vertically provided with a sliding groove 36 on the end surface, and a groove structure matched with the fixing groove 12 is further arranged between the side wall of the clamping plate 31 and the side wall of the fixing groove 12, so that the clamping plate 31 can only move horizontally in the fixing groove 12.

[0037] The insertion groove is further arranged on the side wall of the lower half of the through hole 11, and a connecting portion 33 is slidably arranged in the through hole 11, the upper half of the connecting portion 33 is arranged in a cylindrical shape and is provided with a hinge seat at the center of the top surface, the lower half is arranged in a rectangular shape and is provided with a circular connecting hole at the center of the bottom surface, a screw thread is further arranged on the inner wall of the connecting hole, and the screw thread is movably matched with an adjusting rod 37, the bottom end of the adjusting rod 37 vertically extends to the bottom surface of the box body 1 and is provided with an adjusting cap 38, so that when the adjusting cap 38 is twisted, the adjusting rod 37 and the connecting portion 33 can be moved vertically downward or upward through the screw thread matching structure.

[0038] In the structure, the top surface of the hinge seat is provided with a pair of folding frames 34, and the two folding frames 34 are symmetrically arranged, wherein a single folding frame 34 is composed of a connecting plate A 341 and a connecting plate B 342, the bottom end of the connecting plate A 341 is movably connected with the hinge joint, the top end of the connecting plate A 341 and the bottom end of the connecting plate B 342 are movably hinged, the top end of the connecting plate B 342 is movably hinged with the back surface of the sliding block 35, the sliding block 35 is slidingly assembled in the sliding groove 36, and the side wall of the connecting plate B 342 is further provided with a positioning pin, and the two ends of the positioning pin are fixedly connected with the side wall of the fixed groove 12.
