Then, the end cover 3 is closed, and the end cover 3 and the box body 1 are locked. The buckle 4 is closed, at this time, the slider 551 descends along the guide rail 550, and the support spring 559 is compressed; when the circular oil storage tube 13 and the strip oil storage tube are taken out from the box body 1, the end cover 3 is rotated, and the support spring 559 recovers its deformation during the process, the slider 551 rises along the guide rail 550, the limit seat 552 rises, the column 53, the circular shock-absorbing layer 54 and the circular oil storage tube 13 extend out of the circular oil storage hole 52, the strip barrel 63, the strip shock-absorbing layer 64 and the strip oil storage tube extend out of the strip oil storage hole 62, and there is no need to pull them out manually, which greatly improves the convenience of taking.

[0055] In a possible embodiment, the plugs 556 are arranged corresponding to the connecting holes 511, and a circular oil storage tube 13 is placed in the column 53, the bottom plate 554 is deflected, and the plugs 556 are away from the connecting hole 511; after the circular oil storage tube 13 and the strip oil storage tube at this position are taken out, the bottom plate 554 is deflected during the resetting process of the support spring 559, plugging the plug 556 and closing the connecting hole 511 at this position.

[0056] In a possible embodiment, a circular limiting groove 5541 is provided on the bottom plate 554 away from the bottom hinge shaft 553, and the circular limiting groove 5541 can clamp the bottom of the circular oil storage tube 13 for positioning, and a shock-absorbing layer is fixedly provided on the upper end of the bottom plate 554 to protect the bottom of the circular oil storage tube 13 and the strip oil storage tube, thereby enabling all-round shock-absorbing protection for the circular oil storage tube 13 and the strip oil storage tube.

[0057] In the specific implementation, when the circular oil storage tube 13 and the strip oil storage tube are placed in the box body 1, the lock 4 is opened, the end cover 3 is rotated, the column 53 and the circular shock absorbing layer 54 are placed in the circular oil storage hole 52, the strip cylinder 63 and the strip shock absorbing layer 64 are placed in the strip oil storage hole 62, and the circular oil storage tube 13 is placed in the column 53, and the strip oil storage tube is placed in the strip cylinder 63. The column 53, the circular shock absorbing layer 54 and the circular oil storage tube 13 are connected with the strip cylinder 63 and the strip oil storage tube. The circular shock-absorbing layer 64 and the strip oil storage tube press down the bottom plate 554, and the bottom plate 554 drives the connecting shaft 558 and the deflection shaft 555 to deflect, and the plug 556 is away from the connecting hole 511. The heat flow or cold flow generated by the heating and cooling device 7 enters the circular oil storage hole 52 and the strip oil storage hole 62 along the connecting hole 511, and then the end cover 3 is closed, and the end cover 3 and the box body 1 are sealed by the lock 4. At this time, the slider 551 descends along the guide rail 550, and the support spring 559 is compressed;

[0058] When taking out the circular oil storage tube 13 and the strip oil storage tube from the box body 1, open the lock 4, rotate the end cover 3, and the support spring 559 will recover its deformation. The slider 551 will rise along the guide rail 550, the limit seat 552 will rise, the column 53, the circular shock-absorbing layer 54 and the circular oil storage tube 13 will extend out of the circular oil storage hole 52, and the strip barrel 63, the strip shock-absorbing layer 64 and the strip oil storage tube will extend out of the strip oil storage hole 62. After taking out the circular oil storage tube 13 and the strip oil storage tube at this position, the bottom plate 554 will deflect during the resetting process of the support spring 559, blocking 556 and closing the connecting hole 511 at this position.
