[0024] The electrical connector housing is put on the outside of the clamping mechanism 5, and then the first bidirectional screw 505 in the clamping mechanism 5 is rotated. The first bidirectional screw 505 drives the two connecting plates 503 to slide on the center frame 501, and at the same time, the two connecting plates 503 are moved closer to or away from each other, thereby making the connecting plates 503 cooperate with the connecting rod 504, so that the contact plate 502 moves away from or close to the center frame 501, and the contact plate 502 can then contact the inner wall of the housing, thereby fixing the housing to facilitate the cutting and processing of the housing.
