[0049] Furthermore, when two sets of adjustable mounting components 8 need to be installed, the spacing and angles between the two sets of adjustable mounting components 8 can also be adjusted arbitrarily, which is more adaptable.

[0050] like Figure 4 and Figure 5 As shown, when loading the Dewar flask body 12, the device is first placed vertically on the side of the Dewar flask body 12. At this time, the main support rod 1 is vertically erected close to the Dewar flask, and then the Dewar flask body 12 is slightly tilted to make its bottom tilted, and the support plate 601 is sent to the bottom of the Dewar flask body 12 until the lower positioning seat 6 and the upper positioning seat 7 fit with the Dewar flask body 12, and then the Dewar flask body 12 is clamped into the L hole 1201 on the Dewar flask body 12, and the handle 9 is pulled to tilt the Dewar flask body 12 onto the lower positioning seat 6 and the upper positioning seat 7. After the universal wheel 5 falls to the ground, at this time, the Dewar flask body 12 has been fixed on the lower positioning seat 6 and the upper positioning seat 7, and the Dewar flask can be moved by pushing the device.

[0051] When unloading the Dewar flask body 12, in the same way, the device is vertically erected together with the Dewar flask body 12, and after being kept stable, the adjustable mounting assembly 8 is manually loosened to separate the adjustable mounting assembly 8 from the L hole 1201. At this time, the Dewar flask body 12 has been put down, and the device can be pulled open to complete the unloading.

[0052] Compared with the prior art, the simple Dewar flask transporting device of the utility model is easy to operate and can easily realize the movement and transport of the Dewar flask during short-distance transportation.

[0053] Through the lower positioning seat 6 and the upper positioning seat 7 with adjustable spacing and the adjustable mounting assembly 8 with flexible height adjustment, it is possible to support and fix Dewar flasks of various specifications, thereby facilitating the movement and transportation of Dewar flasks of different specifications.
