[0033] In one embodiment, the driving mechanism includes a motor 18, and the motor 18 is fixedly installed on the rear side of the top of the storage box 2, the driving end of the motor 18 is fixedly installed with a second gear 17, the lower side of the outer wall of the rotating shaft 9 is fixedly installed with a first gear 16, and the first gear 16 is meshed with the second gear 17, and a protective box 8 is fixedly installed on the rear side of the top of the balance body 1, and the driving mechanism is located inside the protective box 8. The protective box 8 can effectively protect the driving mechanism to prevent it from being exposed and accidentally touched by the staff.

[0034] In one of the preferred embodiments, a drawer 3 is slidably installed inside the storage box 2 between the back side of the partition 4 and the rear side of the inner wall of the storage box 2 .

[0035] In one of the embodiments, the front and back sides of the placement plate 7 close to the balance body 1 are fixedly installed with limit blocks 19, the front side of the inner wall of the storage box 2 and the front side of the partition 4 are provided with sliding grooves adapted to the limit blocks 19, and the sliding grooves are slidably connected to the limit blocks 19, thereby achieving stable sliding contact between the placement plate 7 and the storage box 2.

[0037] The working principle of the utility model is as follows: the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing public power connection technology is not repeated in the text. When the balance body 1 needs to be calibrated, the staff first manually pulls the pull plate 6, and the movement of the pull plate 6 drives the placement plate 7 to move. The movement of the placement plate 7 drives the limit block 19 to slide on the inner wall of the storage box 2 and the slide groove on the front side of the partition 4. As the placement plate 7 is pulled out, the limit block 19 at the top of the placement plate 7 The weights 5 are all moved out to one side of the storage box 2, and then the control motor 18 starts to work. The driving end of the motor 18 drives the second gear 17 to rotate. Through the meshing of the second gear 17 and the first gear 16, the first gear 16 drives the shaft 9 to rotate. The rotation of the shaft 9 drives the cross rail 10 to move. The cross rail 10 drives the cylinder 12 to move through the electric slider 14. The cylinder 12 drives the electromagnet 11 to move through the cooperation of the mounting plate 13 and the buffer block 15. Therefore, the electric motor 18 can drive the electric motor 18 to move the electric motor 18. The magnet 11 rotates to the top of the placement plate 7, and at the same time controls the electric slider 14 to slide on the cross rail 10, and the moving radius of the electromagnet 11 can be adjusted. Therefore, with the cross rail 10 following the rotation of the rotating shaft 9, the electromagnet 11 can be adjusted to any position on the top of the placement plate 7 where the weight 5 is placed. After determining the position of the electromagnet 11, the cylinder 12 is controlled to start working. The driving end of the cylinder 12 drives the electromagnet 11 to move vertically through the mounting plate 13 and the buffer block 15, so that the electromagnet 11 is close to the corresponding weight 5, and controls The electromagnet 11 adsorbs the weight 5, and moves the weight 5 to the balance body 1 for verification and calibration through the movement of the electromagnet 11. After the verification and calibration are completed, the weight 5 can be reset to the placement slot 24 at the specified position on the top of the placement plate 7 through the electromagnet 11, and then the pull plate 6 is manually closed to store the weight 5 inside the storage box 2. The device uses the storage function of the weight 5 to prevent the weight 5 from contacting the outside world when not in use through the protection of the storage box 2, thereby ensuring the accuracy of the use of the weight 5 and accurate measurement results. Secondly, in order to improve the flexibility of the use of the electromagnet 11, the device introduces an electric slider 14, which can slide along the cross rail 10. By adjusting the position of the electric slider 14, the movement range and position of the electromagnet 11 can be effectively adjusted. This enables the electromagnet 11 to flexibly adsorb and release the weight 5 on the placement plate 7, providing convenience and flexibility of operation for users.

[0038] During the process of storing the weights 5, the pull plate 6 is closed on the side of the storage box 2, and the clamping columns 21 on the pull plate 6 will be directly clamped into the inside of the clamping groove 23 on the storage box 2, and the elastic clamping connection between the clamping column 21 and the clamping groove 23 is achieved through the elastic metal sheet 22 inside the clamping groove 23, which has a limiting effect on the position of the pull plate 6, making the placement of the placement plate 7 inside the storage box 2 more stable, ensuring the stable storage of the weights 5.

[0039] During use, the storage box 2 has its internal space divided into two parts by the partition 4. The space in front of the partition 4 can be used to store weights 5, and the space behind the partition 4 can be provided with a drawer 3 to increase a storage space, which is convenient for the staff to store other tools, thereby realizing the rational use of the space of the storage box 2 and improving its functionality.
