The slider rod 421 is fixed to the edge portion 4232 through the corresponding fixing portion 4231, so that the snap rings 422 and 422 'and the chuck 423 are sequentially fixed to the slider rod 421 from top to bottom, and an accommodating space is defined by the inner sides of the snap rings 422 and 422' and the chuck 423. The storage chamber 41 is disposed in the receiving space from the upper end of the receiving space downward, so that the inner sidewalls of the two ring portions 4222, 4222' are closely attached to the outer sidewall of the storage chamber 41, and the bottom end of the storage chamber 41 is supported by the base plate 4233. The mounting rack 42 can protect the storage compartment 41 and prevent the storage compartment 41 from being extruded and deformed.

Referring to fig. 2 and 3, each of the slider rods 421 is provided with two

hinge joints

4211 and 4212, the two

hinge joints

4211 and 4212 are respectively located at the upper end and the lower end of the slider rod 421, the hinge joint located at the upper end of the slider rod 421 is an upper hinge joint 4211, and the hinge joint located at the lower end of the slider rod 421 is a lower hinge joint 4212.

Referring to fig. 1 and 2, each of the expanding structures 2 further includes an upper post rod 23 and a lower post rod 24, both the upper post rod 23 and the lower post rod 24 are connecting rods, one end of the upper post rod 23 is hinged to the second hinge portion 212 of the corresponding upper expanding rod 21, and the other end is hinged to the upper hinge portion 4211.

Referring to fig. 2, 4 and 5, the driving frame further includes an upper fixed tray 1 and a lower fixed tray 3, the edge of the upper fixed tray 1 is symmetrically provided with a plurality of first hinge lugs 11, the edge of the lower fixed tray 3 is provided with a plurality of second hinge lugs 31 corresponding to the first hinge lugs 11 in the vertical direction one by one, each of the second hinge lugs 31 includes a limiting spoke 312 and two suspension arms 311 disposed at two opposite sides of the limiting spoke 312, the first hinge portion 211 of each upper supporting expansion rod 21 is hinged to the corresponding first hinge lug 11, and the third hinge portion 221 of each lower supporting expansion rod 22 is hinged to the corresponding second hinge lug 31, so that the upper supporting expansion rod 21 can rotate with the corresponding first hinge lug 11 as a rotation base point, and the lower supporting expansion rod 22 can rotate with the corresponding second hinge lug 31 as a rotation base point. And the upper expansion rod 21 and the lower expansion rod 22 are hinged to the two corresponding suspension arms through rivets respectively, and the limiting spoke 312 is located at the outer side of the suspension arm 311 to prevent the lower expansion rod 22 from rotating excessively outwards. When the lower expansion rod 22 rotates excessively outwards, the expansion structure 2 is expanded excessively outwards, so that the contact spoke B excessively abuts against the elastic sleeve outwards to break the elastic sleeve or lose elasticity.

Referring to fig. 2 and 4, the upper fixing tray 1 is provided with an object inlet 12, an object inlet facing the object inlet 12 is provided on an upper end surface of the storage compartment 41, and a storage object (such as a coin) is put into the storage compartment 41 through the object inlet 12 and the object inlet.

When the storage compartment 41 is empty, the inner container 4 is in an initial position, and at this time, the expansion structure 2 is in the initial state, the expansion structure 2 is folded, and the first free end 213 and the second free end 223 are bent inward to be close to the inner container 4. As the number of the articles to be stored in the inner container 4 increases, the sum of the self weight of the inner container 4 and the total weight of the articles to be stored gradually increases, the inner container 4 sinks under the combined action of the self weight and the pressure of the articles to be stored, the inner container 4 sinks to drive the first hinge portion 211 to rotate relative to the corresponding first hinge lug 11 through the upper push rod 23, so that the upper expansion rod 21 rotates outwards and opens with the hinge portion of the first hinge portion 211 and the corresponding first hinge lug 11 as a base point, and simultaneously the inner container 4 sinks to drive the third hinge portion 221 to rotate relative to the corresponding second hinge lug 31 through the lower push rod 24, so that the lower expansion rod 22 rotates outwards with the hinge portion of the third hinge portion 221 and the corresponding second hinge lug 31 as a base point, at this time, the first free end 213 and the second free end 223 gradually get away from the inner container, that is, the inner container structure 2 is in the expanded state, thereby realizing the outward opening of the expansion structure 2. In the process that the first free end 213 and the second free end 223 are gradually far away from the inner container 4, the included angle between the upper ejector rod 23 and the corresponding upper expansion supporting rod 21 is gradually reduced, so that the upper end of the inner container 4 is gradually far away from the upper fixed tray 1, meanwhile, the included angle between the lower ejector rod 24 and the corresponding lower expansion supporting rod 22 is gradually increased, so that the lower end of the inner container 4 is gradually close to the lower fixed tray 3, the distance that the upper end of the inner container 4 is far away from the upper fixed tray 1 is equal to the distance that the lower end of the inner container 4 is close to the lower fixed tray 3, and therefore the inner container 4 moves between the upper fixed tray 1 and the lower fixed tray 3 to keep the distance between the upper fixed tray 1 and the lower fixed tray 3 unchanged.

So that the canister becomes laterally rounded and inflated but remains vertically at a constant height as the overall weight of the canister increases. The contact spokes B positioned on the outer sides of the upper expansion rod 21 and the lower expansion rod 22 are abutted with the elastic sleeve, and then the elastic sleeve is propped up to enable the elastic sleeve to be elastically deformed and to be expanded outwards, so that the storage tank can be changed in shape.
