[0025] Specifically, the inside of the box 1 is provided with a cavity, and the container is placed in the inside cavity of the box 1 when it is not used, thereby reducing the occupied space. The lower part of the upper cover 2 is provided with a height adjusting structure, so that the height of the container can be adjusted by adjusting the upper cover 2. By rotating the handle, the rotating rod 4 is rotated, and the two bevel gears I 5 connected to the two ends of the rotating rod 4 are also rotated. The two bevel gears II 8 are driven to rotate by the two bevel gears I 5 respectively. The threaded rod 7 can be limited by the cooperation between the fixing block 6 and the inner wall of the box 1, so that the bevel gear II 8 can drive the threaded rod 7 connected thereto to rotate when rotating, so that the two threaded blocks 9 connected to the outside of the threaded rod 7 start to move. The external threads of the threaded rod 7 are symmetrically arranged, so that the two threaded blocks 9 will move closer or farther away from each other, and at the same time, the support rod 10 connected thereto will move at one end, and through the connection between the other end of the support rod 10 and the upper cover 2, the upper cover 2 will be pushed to move, so that the height of the upper cover 2 changes, thereby changing the height of the container 20, facilitating the weighing operation of users of different heights.

[0026] Referring to Figure 3 The fixing assembly comprises a limiting frame 11, a limiting groove 13 is formed in the left and right sides of the inside of the limiting frame 11, a moving block 15 is slidably connected in the limiting groove 13, a pull rod 16 is fixedly connected to one side of the moving block 15, a spring 14 is sleeved outside the pull rod 16, one end of the spring 14 is fixedly connected to the inner wall of the limiting groove 13, the other end of the spring 14 is fixedly connected to the outside of the moving block 15, a clamping plate 18 is fixedly connected to the other end of a connecting rod 17 fixedly connected to the other side of the moving block 15, and a limiting block 19 is fixedly connected to the outer two ends of the clamping plate 18. The outer sides of the two limiting blocks 19 are slidably connected in the inside of the limiting frame 11, and a plurality of supporting legs 12 are fixedly connected to the bottom of the limiting frame 11.

[0027] Specifically, by pulling the pull rod 16 on both sides of the limiting frame 11, the moving block 15 can be driven to slide inside the limiting groove 13, and the limiting groove 13 limits the movement of the moving block 15 and the spring 14 connected therein, so that the moving block 15 is compressed while moving, and drives the connecting rod 17 to move, the connecting rod 17 drives the clamping plate 18 to move, thereby expanding the gap between the two clamping plates 18, then the container 20 is inserted between the two clamping plates 18, and then the pull rod 16 is loosened, at this time the spring 14 begins to recover and releases elastic potential energy to push the moving block 15 to move, so that the two clamping plates 18 clamp and fix the container 20, and the supporting legs 12 support the limiting frame 11, and the supporting legs 12 are in contact with the electronic weighing instrument 3, so that the container 20 does not shake after being fixed, thereby ensuring the stability during weighing and improving the detection accuracy, wherein the limiting frame 11 limits the movement of the limiting block 19, so that the clamping plate 18 can maintain a horizontal state during movement, ensuring good clamping effect.

[0028] Referring to Figure 1 , the upper portion of the electronic weighing instrument 3 is provided with the container 20, the upper portion of the container 20 is provided with the intermediate cylinder 21, and the upper portion of the intermediate cylinder 21 is provided with the grain cylinder 22.

[0029] Specifically, the measured grain is injected into the grain cylinder 22 to realize the addition of the grain, then the switch between the grain cylinder 22 and the intermediate cylinder 21 is opened, so that the grain enters the intermediate cylinder 21, which is convenient for subsequent quantitative measurement of the grain, and finally the switch below the intermediate cylinder 21 is opened, so that the grain enters the container 20, and the container 20 completes the constant volume of the grain, and the electronic weighing instrument 3 can be used for weighing, which can ensure the accuracy of the weighing.

[0030] Working principle: when using the device, due to different heights of users, the placement height of the container will also be different, which makes the container 20 more likely to shake during operation, the handle can be rotated to rotate the rotating rod 4, thereby driving the two bevel gears I 5 connected outside the rotating rod 4 to rotate, the two bevel gears I 5 drive one bevel gear II 8 to rotate, thereby driving the threaded rod 7 connected with the bevel gear II 8 to rotate, so that the two threaded blocks 9 connected outside the threaded rod 7 begin to move, and the support rod 10 connected outside the threaded blocks 9 moves, the support rod 10 supports the upper cover 2, so that the height of the upper cover 2 changes, thereby changing the height of the container 20, which is convenient for users of different heights to perform weighing operation.

[0031] By pulling the pull rod 16 on both sides of the limiting frame 11, the moving block 15 can be driven to slide in the limiting groove 13, thereby compressing the spring 14, and moving the connecting rod 17 through the moving block 15, thereby expanding the gap between the two clamping plates 18, then inserting the container weight cylinder 20 between the two clamping plates 18, then releasing the pull rod 16, at this time the spring 14 restores to its original state and pushes the moving block 15 to move, so that the two clamping plates 18 clamp the container weight cylinder 20, ensuring the stability during weighing measurement, improving the detection accuracy, then the measured grain can be injected into the grain cylinder 22, then the switch between the grain cylinder 22 and the middle cylinder 21 is opened, so that the grain enters the middle cylinder 21, finally the switch below the middle cylinder 21 is opened, so that the grain enters the container weight cylinder 20, after completing the constant volume, the electronic weighing instrument 3 can be used for weighing, which can ensure the weighing accuracy.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
