In a specific application scenario, the device is placed on the ground or a platform, whether the device is in a flat state or not is judged by observing the horizontal correction disc 26, and when the pointer of the horizontal correction disc 26 is not in the center position, the device is not placed stably, and the adjusting assembly 25 needs to be adjusted so as to avoid errors in subsequent bearing operation.

It should be noted that, there is the difference in height ground or platform that the device was placed, and it is relatively poor directly to place its stable state of back with the device, can lead to the landing and the bearing of article to appear the error because of rocking of device at the in-process of weighing afterwards, utilizes the adjustment subassembly to adjust the state of placing of device, makes it satisfy different operational environment, and four independent telescopic movable stay bars 2501 can adjust according to the environmental requirement of reality respectively, the adjustment step: rotating the adjusting knob 2507 causes the adjusting gear 2505 to rotate and engage with the vertical tooth 2504, so as to drive the movable supporting rod 2501 to move up and down, and sequentially adjust the four adjusting assemblies 25 according to the pointer change of the horizontal correcting disc 26, and finally, the pointer of the horizontal correcting disc 26 points to the center vertically and upwards.

When the device is used, the device is placed on the ground or a platform, whether the device is in a flat state or not is judged by observing the horizontal correction disc 26, when the pointer of the horizontal correction disc 26 is not at the central position, the device is not stably placed, the adjusting components 25 need to be adjusted, the adjusting gear 2505 is rotated to be meshed with the vertical teeth 2504 by rotating the adjusting knob 2507, the movable support rod 2501 is driven to move up and down, the four adjusting components 25 are sequentially adjusted according to the pointer change of the horizontal correction disc 26, finally, the pointer of the horizontal correction disc 26 points to the central position vertically upwards, then, an object is placed on the device for weighing operation, the object is placed on the object bearing plate 301, the movable limit block 902 moves downwards under the stress due to the weight of the object in the placing process, the limit spring 903 is compressed to generate elastic deformation, the uncompressed movable limit block 902 keeps the original state, at the moment, the movable limiting block 902 pressed downwards and the movable limiting block 902 kept in the original state form a groove matched with the shape of the object, so that the object is limited on the object bearing plate 301 to avoid moving, meanwhile, after the object bearing plate 301 is pressed, the base 8 rotates on the rotating rod 10, the object bearing plate 301 deflects, the return spring 12 is stretched to generate elastic deformation until the bracket 5 forms a supporting force for the base 8, the two object bearing plates 301 are in a horizontal state, in the process, the inner connecting plate 302 is accommodated in the inner connecting groove 303 under the tensile force of the accommodating spring 309, after weighing is completed, the object is moved away, due to the elastic force of the return spring 12, the two object bearing plates 301 are reset to be in an inclined state, the inner connecting plate 302 slides out of the two inner connecting grooves 303, the accommodating spring 309 is pulled to generate elastic deformation, the rubber connecting block 306 is in an arc shape, and the liquid remained on the object bearing plates 301 can slide downwards and gather in the liquid flowing groove 304, and finally from flowing liquid hole 305 landing, gliding liquid is collected in getting into album liquid box 2301 from falling liquid board 2302, because stock solution chamber 2303 is in sealed environment after rubber buffer 2304 blocks up, liquid can increase album total weight of liquid box 2301 in stock solution chamber 2303, two album liquid boxes 2301 are located the both sides of device and are the symmetric distribution, the range of weight increase is the same to the whole weight of device increases, the whole stability more of device.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
