[0050] Specifically, the driving member 114 is a device that can facilitate the user to rotate the extrusion structure 11, such as a handle 1141, a gear and rack mechanism, etc. In this embodiment, the handle 1141 is preferred. The handle 1141 can be arranged in an L shape or with a circular ring, etc. The user can easily grasp it. The handle 1141 is connected to the end of the extrusion structure 11. Rotating the handle 1141 can drive the extrusion structure 11 to rotate around the first rotating shaft 111. The rotation is realized through the handle 1141, and the structure is simple.

[0051] In some embodiments, the driving member 114 can be a gear and rack mechanism, which is composed of intermeshing gears and racks. The rack is arranged in the grain storage device through a guide rail. The gear is arranged at the end of the extrusion structure 11.

[0059] In some embodiments, as shown in Figures 1-10 The food storage device further comprises a movable placement plate 3 arranged to support and move the storage part 2, so that the opening part 21 of the storage part 2 moves to the gap 13 between the pressing structure 11 and the abutting structure 12, or moves away from the gap 13.

[0060] Specifically, the placement plate 3 can be a flat plate or a wavy plate. The placement plate 3 is arranged to move, such as to slide, rotate, or be driven by a gear, and can support and move the storage part 2. During the movement, the opening part 21 of the storage part 2 can move to the gap 13 or move away from the gap 13. The placement plate 3 can facilitate the access to the storage part 2 and protect the bottom of the storage part 2.

[0068] Specifically, when the user rotates the handle 1141, causing the squeezing structure 11 to squeeze the opening 21 to the contact structure 12 to seal the opening 21, the squeezing action causes the squeezing structure 11 to tend to rotate around the first rotating shaft 111. The locking structure provides a reverse force to the handle 1141, keeping the squeezing structure 11 in a squeezing state. The locking structure can be a snap-fit ​​structure or a torsion spring structure. This design is simple and can prevent accidental operation.

[0069] In some embodiments, such as Figures 1-10 As shown, the grain storage device also includes a support 4, which includes two opposing n-shaped support rods 41.

The opening 21 allows access to the gap 13 through the hollow portion of the n-shaped support 4. Here, the hollow portion is... Figure 6 As shown at point C, when the user stores storage unit 2, through... Figure 6 The hollow section indicated by C places the storage section 2 on the placement plate 3. The opening 21 passes through the gap 13. The user rotates the extrusion structure 11 by operating the handle 1141, thereby sealing the opening 21.

[0071] Furthermore, two n-shaped brackets 4 are arranged opposite each other, and the storage section 2 is placed on the upper side of the placement plate 3. The bottom of the n-shaped brackets 4 is connected to two overlapping parts that support the placement plate 3. The overlapping parts can be plates or columns. The placement plate 3 can move relative to the overlapping parts to allow the storage section 2 to be entered or removed.

[0072] Further, the side of the two n-shaped supports 4 can be provided with a protective plate, which can store the storage part 2 more safely; or the side of the two n-shaped supports 4 is hollow, and the user can directly take the storage part 2 when the storage part 2 is in a non-sealed state.

[0073] In some embodiments, the center axes of the extrusion structure 11 and the contact structure 12 are parallel, two ends of the extrusion structure 11 and the contact structure 12 are connected by connecting rods respectively, the other side end is also connected by a connecting rod, and the extrusion structure 11 and the contact structure 12 can rotate around the first rotation shaft 111 and the second rotation shaft 122 respectively, and the length of the connecting rod can ensure that the extrusion structure 11 can form a gap 13 after moving away from the contact structure 12.
