Coaxial contact fixing performance testing device

The utility model relates to a device for testing the fixing performance of a coaxial contact piece, and the device comprises a housing, an adapter, a connecting rod, a top sleeve, and a movable pressing block, the connecting rod is movably connected in the housing, the connecting rod is sleeved with a spring, the connecting rod is provided with an identification line, and the housing is providedwith an observation hole; the utility model has the advantages that the adapter is contacted with the positioning surface of the coaxial contact piece to be tested, the axial load is applied to the coaxial contact piece to be tested, the connecting rod is driven to retract inwards to enable the identification line to move towards the observation hole, and when the identification line moves into the observation hole, the coaxial contact piece is judged to be installed in place; therefore, the testing device only needs to observe the position of the mark line to judge whether the coaxial contactelement is fixed reliably
