A method for eliminating horizontal offset of a traction testing device and a traction testing device thereof. The device comprises a first single arm cantilever (100) and a second single arm cantilever (100') having the same structure, and a substrate (300). The first single arm cantilever (100) and the second single arm cantilever (100') are disposed in parallel. Two terminals of the first single arm cantilever (100) and the second single arm cantilever (100') at the same side are fixedly connected. The other terminal of the first single arm cantilever (100) or the second single arm cantilever (100') is fixed on the substrate (300). A remaining unfixed free end of the single arm cantilever is connected to a testing tool (400) that has a hook (500). The present invention adopts an offset compensation structure of opposite horizontal displacement, thereby completely solving the problem of the horizontal offset of the unfixed free end of the single arm cantilever. If the testing tool is suspended by use of two sets of oppositely mounted cantilevers having the same structure and disposed in a vertical direction, the effect is better. |
