Referring to fig. 1, the supporting device includes a square base 1, four arc-shaped clamping plates 2 are arranged above the base 1, the four clamping plates 2 are located in the same horizontal plane, and the two adjacent clamping plates 2 are close to each other end to end. When needs are filled the natural gas, place the liquefaction jar and lie in the position in the middle of four pinch plates 2 on base 1, four pinch plates 2 are cyclic annular this moment and are located the circumference of liquefaction jar.

Referring to fig. 2, a cavity 11 is formed in the base 1, two driving assemblies 3 which are vertically distributed and perpendicular to each other are arranged in the cavity 11, each driving assembly 3 is connected with two clamping plates 2 which are oppositely arranged, and drives the two clamping plates 2 which are oppositely arranged to move towards a close direction or a separated direction, so that the liquefaction tanks with different diameters can be clamped.

Referring to fig. 1 and 2, a strip-shaped hole 12 is respectively opened at the position opposite to each clamping plate 2 on the upper surface of the base 1, the driving component 3 comprises a bidirectional screw 31 which horizontally penetrates through the base 1 and is positioned inside the base 1, and two ends of the bidirectional screw 31 are rotatably connected with the side wall of the base 1. Two parts of the bidirectional screw rod 31 with opposite rotation directions are respectively in threaded connection with a connecting plate 32, and the top of the connecting plate 32 upwards penetrates through the long-strip-shaped hole 12 and is fixedly connected with the lower surface of the clamping plate 2. The width of the connecting plate 32 is the same as the width of the elongated hole 12, so the side wall of the connecting plate 32 fits the side wall of the elongated hole 12, and the connecting plate 32 can slide stably along the elongated hole 12 when the driving assembly 3 drives the clamping plate 2 to move. One end of the bidirectional screw 31 protrudes out of the base 1, and a hand wheel 33 is fixedly connected to one end of the bidirectional screw 31 protruding out of the base 1.

When the liquefaction tank needs to be clamped, the hand wheel 33 is rotated and the bidirectional screw rod 31 is driven to rotate, the two opposite clamping plates 2 can be driven to move towards opposite directions when the bidirectional screw rod 31 rotates, and the liquefaction tank can be clamped when the distance between the centers of the two clamping plates 2 is equal to the diameter of the liquefaction tank.

Referring to fig. 2 and 3, when the clamping plates 2 are used for clamping the liquefaction tank, looseness may occur, which may cause the liquefaction tank to topple over, and in order to further reduce the possibility of the liquefaction tank toppling over, the tensioning assemblies 4 are arranged at the bottoms of the two opposite connecting plates 32, so that the possibility of looseness of the two opposite clamping plates 2 can be reduced.

The tensioning assembly 4 comprises a bushing 41 fixedly connected to one of the connection plates 32 and a connecting rod 42 fixedly connected to the other connection plate 32, the connecting rod 42 being slidably inserted with the bushing 41. The connecting rod 42 is fixedly connected with a limiting block 43 at the end part inside the sleeve 41, the diameter of the limiting block 43 is larger than that of the connecting rod 42, and the connecting rod 42 can be prevented from being separated from the sleeve 41 by arranging the limiting block 43.
