[0027] Different from the traditional four installation positions, the present application is further simplified to two installation positions. On the female head fixing plate 3, through the floating components 5 located at the two ends, the present application can achieve self-correction to a certain extent, which can solve the problem of relative position deviation during installation and the problem of Z-axis travel tolerance causing destructive damage to the interface during rigid insertion.
