Abstract
Description
Technical Field

[0002] Currently, the main method of measurement in the production process is to use fixed fixtures and torque wrenches. However, due to the diversification of car key shapes, a set of fixed fixtures cannot meet the measurement of various key models, so more fixed fixtures need to be invested. In addition, the measurement method using torque wrenches requires manual operation, and the data also needs to be recorded manually, which makes the entire measurement time-consuming. Furthermore, there are cases of omissions or errors in the manual data recording. Utility Model Content

[0025] Reference Figure 1-3 The detection mechanism includes a connecting sleeve 14 and a detection shaft 19. A coupling 17 is fixedly installed on the upper surface of the positioning vertical plate 12. A torque sensor and an angle sensor are installed inside the coupling 17.
