Overload protection structure of electronic weighing instrument

The utility model relates to the technical field of electronic weighing instruments, and discloses an electronic weighing instrument overload protection structure, which comprises a weighing platform and a base, a hydraulic pump is arranged between the weighing platform and the base, a mounting seat is fixedly mounted on the bottom side of the weighing platform, and a mounting groove is formed in the top side of the base. Under the overload condition, in the process that the fixing rod and the first linkage rod continue to move, the linkage heads are mutually clamped to drive the second linkage rod to move downwards, the linkage effect is achieved, then the first rack is driven to move downwards, transmission is conducted under the action of the gear, the second rack is driven to move reversely, and therefore the rubber base is driven to ascend; therefore, the rubber block on the bottom side of the weighing platform is in contact with the rubber seat, a supporting effect is provided, buffering protection is f
