[0030] The limiting mechanism 4 includes a limiting unit and a transmission unit;

[0031] The limiting unit is used to provide a limit for the connection between the connecting rod 2 and the supporting rod 3;

[0032] The transmission unit is used to provide power for the movement of the limit unit;

[0033] The limiting unit includes a limiting groove 401, a limiting block 402, and a movable block 403;

[0034] The limiting groove 401 is provided on the outer wall of the support rod 3, and the limiting groove 401 is used to provide a space for inserting the limiting block 402;

[0035] The limit block 402 is axially slidably installed in the inner cavity of the connecting rod 2, and the limit block 402 is used to cooperate with the limit groove 401 to provide connection limit for the support rod 3 and the connecting rod 2;

[0036] The movable block 403 is fixed to the end of the limit block 402 and is located on the inner wall of the connecting rod 2. The movable block 403 is used to drive the limit block 402 to move synchronously.

[0037] The transmission unit includes a rotating ring 404, a torsion spring 405, a stop rod 406, and a guide groove 407;

[0038] The rotating ring 404 is rotatably sleeved on the outer wall of the connecting rod 2, and the rotating ring 404 is used to drive the supporting rod 406 to rotate synchronously;

[0039] The two ends of the torsion spring 405 are respectively fixed to the inner wall of the connecting rod 2 and clamped to the top of the rotating ring 404. The torsion spring 405 is used to provide a restoring elastic force for the rotating rotating ring 404.

[0040] The push rod 406 is fixed at the bottom end of the rotating ring 404 and extends to the inner cavity of the guide groove 407. The push rod 406 is used to give thrust to the guide groove 407 during the rotation process;

[0041] The guide groove 407 is provided on the outer wall of the movable block 403, and the guide groove 407 is used to transmit the rotation thrust from the pair of abutment rods 406 to the movable block 403;

[0042] A socket is provided at the bottom of the connecting rod 2 to connect with the bottom end of the supporting rod 3 , and one end of the socket is electrically connected to the internal system of the weighing platform 1 through a wire.

[0043] In this embodiment: when this device is used, by giving a rotational force to the rotating ring 404, the rotating rotating ring 404 will synchronously drive the support rod 406 fixed at the bottom to rotate synchronously, and the torsion spring 405 clamped at the top will also be subjected to a rotational torque from the rotating ring 404. The rotation of the support rod 406 will give a rotational thrust to the guide groove 407, and the guide groove 407 is forced to drive the movable block 403 to move toward the inside of the connecting rod 2. The movement of the movable block 403 synchronously pulls the limit block 402 to move until the limit block 402 moves out of the end of the limit groove 401. At this time, an upward pulling force can be given to the connecting rod 2, thereby separating the connecting rod 2 from the support rod 3, and the limit block 402 and the movable block 403 will also be reset under the torsion of the torsion spring 405, thereby achieving the purpose of quickly separating the connecting rod 2 and the support rod 3, so that the support rod 3 can be in a flat state, which is convenient for carrying the support rod 3 and the weighing platform 1.

[0044] Please refer to Figure 1-Figure 3 There are two limit blocks 402 and movable blocks 403, which are symmetrically distributed on the inner wall of the connecting rod 2. The inner wall of the limit groove 401 matches the outer wall of the limit block 402. The inner wall of the weighing platform 1 is formed with a sliding groove for axial movement of the limit block 402 and the movable block 403. The outer wall of the guide groove 407 is inclined as a whole, and the inner cavity of the guide groove 407 matches the outer wall of the support rod 406.

[0045] In this embodiment: through this structure, the rotational force can be transmitted to the push rod 406 when the rotating ring 404 rotates. Since the guide groove 407 is inclined and symmetrically distributed on the outer wall of the movable block 403, the rotating push rod 406 will give a pulling force to the movable block 403 and the limit block 402, so that the two limit blocks 402 synchronously enter the inner cavity of the connecting rod 2 and separate from the limit groove 401.

[0046] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
