AI Technical Summary
When traditional automotive repair data rulers rely on manual visual judgment and simple bubble level to adjust the level of the bottom pins of the first and second support rods, there are large errors in manual judgment and limited accuracy of the bubble level. This results in repeated adjustments to barely make the two pins close to level, which consumes a lot of time and effort and reduces work efficiency.
The system employs a leveling mechanism in conjunction with a laser reflector ball. By aligning the laser emitter with the laser reflector ball, the horizontal positions of the first and second support rods are precisely adjusted. Limiting blocks and scales enhance the stability and convenience of measurement. A sliding vernier caliper and a pull-out ruler are also included to accommodate different measurement needs.
It enables rapid and accurate measurement benchmark setting, improves measurement accuracy and efficiency, enhances the applicability and flexibility of the data ruler, and is suitable for automotive repair scenarios with high measurement accuracy requirements.
