[0002] The vehicle-mounted scales on the market mainly use column-type weighing sensors, which connect the two ends of multiple column-type weighing sensors to the frame and the bottom of the truck bed respectively to weigh the goods in the truck bed. In order to maintain the weighing accuracy of the vehicle-mounted scale, the vehicle-mounted scale needs to be calibrated and maintained regularly to ensure its weighing reliability and accuracy.

[0003] In the prior art, since the vehicle-mounted scale is not easy to disassemble, cargo of standard weight is usually placed on the truck bed, and the measurement accuracy of the vehicle-mounted scale is evaluated by comparing the sensor reading with the actual weight of the cargo. Although this method is intuitive, it is inconvenient to operate: the loading and unloading process of the cargo is time-consuming and labor-intensive; cargo of a specific weight can only be accurately detected within a limited range of the vehicle-mounted scale, and the accuracy detection effect of the weight outside this range cannot be guaranteed; therefore, the present application provides an accuracy detection device for a vehicle-mounted scale.

[0010] Furthermore, a linear electric cylinder is installed between the two slide arms to control the two slide arms to slide relative to each other.

[0011] Furthermore, the fixed end and the movable end of the linear electric cylinder are rotationally connected to the handle I and the handle II respectively.

[0012] Furthermore, guiding slopes are arranged on the inner sides of the two insertion arms.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
