In the pulling-out process, after the detection box 2 reaches a specified position upwards, the detection program is automatically completed, at this time, the friction rod 5 is separated from the reciprocating control rod 704, so that the friction rod 5 loses the fixing effect on the wear-resistant outer ring 401 in the detection process, the wear-resistant outer ring 401 moves upwards under the effect of the residual elastic potential energy, as most of the spring potential energy has enabled the detection box 2 to rise to complete detection, the residual elastic potential energy only can raise the electric connector by one third of the height, the detection personnel can pull out the electric connector outwards after knowing that the detection is completed, the reverse acting force generated by pulling-out action performed at this time is transmitted to the detection box 2 through the transmission component 4, the detection box 2 is restored downwards to the initial position under the effect of the inverted sloping plate 702, the whole detection process is completed, and all potential energy in the interior is completely consumed.
Secondly, the problem that the piece to be detected is easy to move in the detection process is solved;
in the process of inward movement of the bottom inclined blocks 701 on two sides under the action of the gear worm 703, the reciprocating control rod 704 moves synchronously inwards along with the bottom inclined blocks 701, the top of the flat inclined block 7042 is provided with a plurality of inclined slotted holes, the slotted holes have upward movement trend when moving inwards, the friction rod 5 is pushed to move upwards, the top of the friction rod 5 is contacted with the wear-resistant outer ring 401 to achieve the effect of fixing the outer surface of the electric connector, when the detection of outward movement of the reciprocating control rod 704 which is restored to the original state is completed, the inclined slotted holes do not have upward pushing force on the friction rod 5, and the friction rod 5 does not have the effect of preventing the rotation of the wear-resistant outer ring 401.
