Description

[0002] As Figure 1 shown in the figure, the existing structure of a product to be tested, such as the connecting rod of a clothes hanger, is usually composed of a main rod 1 and multiple support rods 2. The multiple support rods are welded on both side surfaces of the main rod. After welding is completed, it is necessary to detect the welding strength of the support rods to determine whether the welding strength meets the load-bearing requirements of the support rods. Currently, this detection process requires manual operation to separately perform tensile strength tests on multiple support rods through a tensile testing machine. The entire detection process is time-consuming and laborious, consuming a large amount of manual labor and having low detection efficiency. Summary of the Utility Model
