At the same time, the guardrails 702 protect the sides of the extension plates 701, preventing the agricultural products from falling during the weighing process and ensuring the safety of the weighing operation.

[0041] In this embodiment, a charging unit 5 is arranged on the machine body 1. A connection port 501 is arranged on the machine body 1. A storage battery 502 is arranged inside the connection port 501 and is electrically connected to the connection port 501 through a circuit. The storage battery 502 provides power for each electronic element in the machine body 1. The storage battery 502 is connected to a cover plate 503, and the cover plate 503 is connected to the connection port 501 in a buckle connection manner.

[0042] In actual use, the user can place the storage battery 502 in the connection port 501 to supply power to the machine body 1. When replacing the storage battery 502, the user can pull out the cover plate 503 and the storage battery 502 from the connection port 501.

The positioning mechanism 8 is used to fix the driving mechanism 6, which ensures that the driving mechanism 6 will not displace or shake during work, thereby ensuring the control of the position of the extension plates 701.

[0046] The driving mechanism 6 comprises a frame 601, two rod bodies 602, two connecting plates 603, two circular rollers 604, two plate bodies 605 and two limiting grooves 606. The frame 601 is in the shape of a trapezoid. Two slide rods 607 are fixed below the scale disc 4, and both slide rods 607 pass through the frame 601, so that the frame 601 can only slide along the slide rods 607.

The connecting plates 603 are connected with the rod bodies 602.

[0047] In actual use, when the user needs to adjust the size of the scale disc 4, the frame 601 can be pushed, and the frame 601 drives the round roller 604 to rotate in the limiting groove 606 during the movement, at this time, the two rod bodies 602 move away from each other, and the two extension plates 701 are synchronously moved by the same distance during the movement of the two rod bodies 602, so that the extension distance of the two extension plates 701 is synchronously adjusted, which is convenient for the user to operate.

[0048] In the embodiment, the positioning mechanism 8 comprises two limiting plates 801, a top plate 802, two positioning grooves 803, two clamping blocks 804, two first blocks 805, two second blocks 807, two inserting rods 806 and a plurality of inserting grooves 812. The two limiting plates 801 are connected with the scale disc 4. The top plate 802 is attached to the two limiting plates 801, and the top plate 802 is connected with the frame 601, and the top plate 802 can drive the frame 601 to move synchronously during the movement. The two positioning grooves 803 are processed on the top plate 802, and the clamping block 804 is slidably connected between the positioning groove 803. The two ends of the clamping block 804 are respectively connected with the first block 805 and the second block 807, and the mutually close sides of the first block 805 and the second block 807 are respectively attached to the upper and lower sides of the top plate 802, so that the inserting rod 806 can only move linearly along the positioning groove 803. The first block 805 is connected with the inserting rod 806, and a plurality of inserting grooves 812 are equally spaced on the limiting plate 801. The inserting rod 806 can be inserted into different inserting grooves 812 according to different use requirements, and the positioning of the driving mechanism 6 is realized through the cooperation of the inserting rod 806 and the inserting groove 812.

[0049] In actual use, the user can press the two second blocks 807 to move towards each other, at this time, the inserting rod 806 is separated from the inserting groove 812, at this time, the user can push the frame 601 to move linearly to adjust the position, when the frame 601 is adjusted to the appropriate position, the user can pull the two second blocks 807 to move away from each other, at this time, the inserting rod 806 is inserted into the corresponding inserting groove 812 for fixation, the positioning of the driving mechanism 6 is realized, and it is convenient for the user to operate.

[0050] In the embodiment, the positioning mechanism 8 further comprises a back plate 809, two limiting rods 810, two springs 811 and two protrusions 808.

The springs 811 play a role of elastic reset in the whole positioning mechanism 8, when it is needed to adjust the position of the insertion rod 806, the elastic force of the springs 811 can be overcome to make the second block 807 drive the insertion rod 806 to be pulled out of the insertion slot 812; after the insertion rod 806 is inserted into the insertion slot 812, the springs 811 provide a certain elastic force to make the insertion rod 806 keep in contact with the insertion slot 812, prevent the insertion rod 806 from being accidentally pulled out, and ensure the reliability and stability of the positioning mechanism 8.

[0051] In actual use, when the user needs to release the locking of the positioning mechanism 8, the two protrusions 808 can be pulled to move towards each other, at this time, the two protrusions 808 overcome the elastic force of the springs 811 to make the insertion rod 806 separate from the insertion slot 812, so as to allow the driving mechanism 6 to drive the extension plate 701 to adjust the position again; and in the locking process, the elastic force of the springs 811 ensures that the insertion rod 806 is stably inserted into the insertion slot 812, avoids the positioning failure caused by vibration or other external force, and ensures the stability and reliability of the electronic scale in the weighing operation.
