[0037] Example 2:

[0038] Reference Figures 1-5The bottom of the mounting box 201 is provided with a gripping component 3, which includes an adjustment box 301. A stepper motor 302 is fixedly installed on one side of the inner cavity of the adjustment box 301. A positive and negative threaded rod 303 is fixedly installed on the output shaft of the stepper motor 302. Adjusting screw blocks 304 are threadedly connected to both sides of the surface of the positive and negative threaded rod 303. A connecting rod 306 is fixedly installed at the bottom of the adjusting screw block 304. A second electric push rod 307 is fixedly installed at one end of the connecting rod 306. A support plate 308 is fixedly installed at the output end of the second electric push rod 307. The front and rear sides of the inner cavity of the support plate 308 are fixedly installed with... There is a third electric push rod 309, and an extension plate 310 is fixedly installed at the output end of the third electric push rod 309. A guide block 305 is fixedly installed on the top of the adjusting screw block 304. A guide groove is opened in the inner cavity of the adjusting box 301. A limit plate 311 is fixedly installed at the bottom of the connecting rod 306. A ventilation hole is opened on the surface of the limit plate 311. A positioning bearing is fixedly installed on the other side of the inner cavity of the adjusting box 301, and the positioning bearing is rotatably connected to the positive and negative threaded rod 303. There are four third electric push rods 309 and four extension plates 310. The surfaces of the support plate 308 and the extension plate 310 are both provided with inclined grooves.

[0039] In this embodiment: by setting up a gripping component 3, the distance between the pallet 308 and the limiting plate 311 can be adjusted by controlling the extension and retraction of the second electric push rod 307, which is convenient for adjustment according to the height of the cargo box. The position of the extension plate 310 can be adjusted by controlling the extension and retraction of the third electric push rod 309, which is convenient for adjustment according to the width of the cargo box. The distance between the two pallets 308 can be adjusted by controlling the forward and reverse rotation of the stepper motor 302, which is convenient for adjustment according to the length of the cargo box. The guide block 305 works in conjunction with the guide groove to limit the adjustment screw block 304, making the adjustment screw block 304 stable when moving.

The four third electric push rods 309 and the extension plate 310 form four sets of positioning components, which can support the bottom of the cargo box from all sides.

[0040] The implementation principle of this utility model is as follows: In use, by controlling the extension and retraction of the third electric push rod 309, the position of the extension plate 310 can be adjusted to facilitate adjustment according to the width of the cargo box. By controlling the extension of the second electric push rod 307, the pallet 308 is pushed downward, thereby driving the third electric push rod 309 and the extension plate 310 downward, so that the two pallets 308 are located on both sides of the cargo box. The stepper motor 302 is turned on to drive the positive and negative threaded rod 303 to rotate. The positive and negative threaded rod 303 drives the two adjusting screw blocks 304 to move closer to each other through the threads on both sides of the surface, so that the pallets 308 and the extension plate 310 are inserted into the bottom of the cargo box, and the limiting plate 311 is in contact with the sides of the cargo box. Controlling the retraction of the second electric push rod 307 can drive the pallet 308 to move upward, thereby driving the top of the cargo box to be in contact with the top of the inner cavity of the limiting plate 311, thus making the cargo box stable.
