[0060] Working principle: When in use, the push handle 16 is pushed to move the device to the use position through the universal wheel 17, and the first cylinder 51 is retracted. During the retraction process, the first slider 53 on the mounting seat 52 moves along the first slide groove 54, and the end of the support plate 4 away from the connecting plate 3 will tilt downward until it contacts the ground. At this time, the user can move the liquefied tank along the inclined surface to the support plate 4 and place the liquefied tank into the placement groove 11. Under the elastic force of the second spring 105, the two second clamping plates 104 clamp the lower part of the liquefied tank, and the first cylinder 51 is extended to turn the support plate 4 back to a horizontal state. The height of the first clamping plate 93 is adjusted by the second cylinder 8, and then the threaded rod 62 is driven to rotate by turning the knob 64, and the threaded rod 62 drives the threaded block 63 along the slot 6 1 moves, thereby driving the moving plate 7 to move, and then driving the second cylinder 8 and the first clamping plate 93 to move in the direction close to the liquefied tank. After the first clamping plate 93 contacts the liquefied tank, continue to turn the knob 64, the second cylinder 8 and the mounting plate 91 continue to move in the direction of the liquefied tank. At this time, the first spring 94 is compressed, and the first clamping plate 93 is subjected to the elastic force of the first spring 94, so that the first clamping plate 93 clamps the upper part of the liquefied tank, thereby improving the clamping stability. At the same time, the reinforcing plate 13 extends out of the movable groove 12 to support the bottom of the supporting plate 4, and drives the fixing plate 15 to lean towards the ground through the third cylinder 14 until the fixing plate 15 contacts the ground, thereby supporting the first bottom plate 1 and the second bottom plate 2, thereby improving the supporting effect and improving the stability during the filling process of the liquefied tank.
