[0002] The traditional tensile test tooling uses the head of bolt-like parts as a limit for tensile tests. However, the head of the hub bolt is small. When using the traditional tooling, the head of the hub bolt cannot bear the maximum load generated in the tensile test, and the tensile strength of the bolt cannot be measured.

[0003] In the prior art, the patent (CN221038373U) proposed a tensile test tooling for an automobile hub bolt, including a bolt body and an auxiliary device. The auxiliary device includes a first positioning seat, a second positioning seat, a first clamping seat, a second clamping seat and a connecting component. The first positioning seat is slidably connected to the bolt body, the second positioning seat is slidably connected to the bolt body, the first clamping seat is detachably connected to the first positioning seat, the second clamping seat is detachably connected to the second positioning seat, and the connecting component is arranged on the side of the first clamping seat close to the second clamping seat. When the tensile force of the bolt body is detected, multiple groups of bolt bodies are positioned through the first positioning seat and the second positioning seat. Then, an external tensile testing machine can respectively clamp the first clamping seat and the second clamping seat and pull them, so as to realize the tensile test of multiple groups of bolt bodies. Furthermore, when performing the tensile test of the automobile hub bolt, the tensile test of multiple groups of bolts can be realized simultaneously, which is more conducive to detection and use.

[0004] However, in the above prior art, the head of the hub bolt is small, and the head of the hub bolt cannot bear the maximum load generated in the tensile test, and the tensile strength of the bolt cannot be measured. Content of the Utility Model

[0006] To achieve the above object, the utility model provides a tensile test tooling for a hub bolt with a thin head, which includes a positioning seat, a first connection component, a second connection component, an installation component and an anti - detachment component.
