The first arc-shaped clamping plate 9 abuts against the edge of the socket 3.

[0024] Please refer to Figure 1 and 4Before the stress test, the plug 2 and the socket 3 need to be fully connected, and then suspended between the support seat 4 and the traction seat 5, and the two drag plates 7 are first driven to approach each other by the second driving mechanism, so that the drag plate 7 drives the second arc-shaped clamping plate 10 to fit the surface of the plug 2, and one side of the second arc-shaped clamping plate 10 is in contact with the edge of the socket 3, and then the two limit plates 6 are driven to approach each other by the first driving mechanism, so that the limit plate 6 drives the first arc-shaped clamping plate 9 to fit the surface of the first arc-shaped clamping plate 9, and the surface of the first arc-shaped clamping plate 9 is in contact with the edge of the socket 3, and then the staff keeps the positions of the socket 3 and the plug 2 unchanged, and slightly adjusts the position of the traction seat 5 by the cylinder 8. Move a distance in the direction away from the plug 2, at this time, the drag plate 7 drives one end of the first arc-shaped clamping plate 9 to be pulled out from between the plug 2 and the second arc-shaped clamping plate 10, and makes the surface of the first arc-shaped clamping plate 9 contact the protruding part of the plug 2, and then slightly open the two drag plates 7 through the second driving mechanism, so that the first arc-shaped clamping plate 9 does not contact the side of the plug 2, and the plug 2 and the socket 3 can be released at this time, and the plug 2 and the socket 3 can be kept suspended under the pulling force of the first arc-shaped clamping plate 9 and the second arc-shaped clamping plate 10 respectively, and finally, the traction seat 5 is continuously moved in the direction away from the plug 2 by the continuous output of the cylinder 8, so as to pull the connection between the plug 2 and the socket 3 for stress testing.

[0025] The first driving mechanism includes a first threaded rod 11, a first motor 12 and a first rotating shaft 13. The first motor 12 is fixed to the bottom of the support seat 4. The first rotating shaft 13 is rotatably set on the surface of the support seat 4. The first threaded rod 11 is rotatably set on the surface of the support seat 4. The limiting plate 6 is threadedly connected to the surface of the first threaded rod 11. The second driving mechanism includes a second threaded rod 14, a second motor 15 and a second rotating shaft 16. The second motor 15 is fixed to the bottom of the traction seat 5. The second rotating shaft 16 is rotatably set on the surface of the traction seat 5. The second threaded rod 14 is rotatably set on the surface of the traction seat 5. The dragging plate 7 is threadedly connected to the surface of the second threaded rod 14. The surfaces of the first threaded rod 11 and the second threaded rod 14 are both provided with smooth sections 17. The first rotating shaft 13 and the second rotating shaft 16 are respectively connected to the two smooth sections 17 through a bevel gear set 18.

[0026] See also Figure 2 and 3, the first motor 12 and the second motor 15 can respectively drive the first rotating shaft 13 and the second rotating shaft 16 to rotate through the bevel gear set 18, and the first rotating shaft 13 and the second rotating shaft 16 can respectively drive the first threaded rod 11 and the second threaded rod 14 to rotate, so as to realize the movement of the limiting plate 6 and the dragging plate 7, thereby respectively realizing the horizontal limitation of the plug 2 and the socket 3. The purpose of selecting screw drive is to be able to accurately adjust the horizontal positions of the limiting plate 6 and the dragging plate 7, so that the first arc-shaped clamping plate 9 and the second arc-shaped clamping plate 10 can respectively move a relatively accurate stroke.

[0027] The surface of the base 1 is fixedly provided with a T-shaped track, and the bottom of the traction seat 5 is provided with a chute 20 matching the T-shaped track.

[0028] Please refer to Figure 1 and 3 , when the traction seat 5 moves, it can move synchronously on the surface of the T-shaped track 19 through the chute 20. The T-shaped track and the chute 20 can play a guiding role in the movement process of the traction seat 5, and the bottom of the traction seat 5 will not contact the surface of the base 1 during the movement process, so the interference caused by this part of the friction can be excluded. And when the traction seat 5 moves, it can drive the roller 22 to move synchronously through the bracket 21. Since the bottom of the roller 22 is in contact with the base 1, a rolling friction force can be generated between the roller 22 and the base 1 at this time, minimizing the influence on the stress test process under the condition of ensuring the stable translation of the traction seat 5.
