When the penetration rod 3 enters the connecting sleeve 2, the positioning block 1002 passes through the fixed shell 1001 and enters the placement hole 1006 for limitation. The electromagnet 1005 is started to push the limit plate 1003 with the same magnetic pole to slide along the limit shell 1004, thereby resisting the penetration rod 3 to cooperate with the clamping groove 504 and the positioning hole 505 to limit the position, which can improve the stability of the penetration rod 3 after positioning.

The internal spring of the support rod 501 pushes the sliding rod 502 to pass through the positioning hole 505 for re-positioning and improving the connection stability. The lower pressure ring 506 threadedly connected to the connecting sleeve 2 resists the sliding rod 502 to increase stability, and the clamping ring 6 clamps the sliding rod 502 through the clamping hole 7 The limiting operation is performed, and the supporting ring 9 threadably connected to the connecting sleeve 2 is rotated, and is rotatably connected to the locking ring 6 via the limiting rod 8, thereby improving the positioning stability of the sliding rod 502. When the protruding rod 3 enters the connecting sleeve 2, the positioning block 1002 passes through the fixed shell 1001 and enters the placement hole 1006 for limiting the position. At the same time, the electromagnet 1005 works to push the limiting plate 1003 with the same magnetic pole to slide along the limiting shell 1004, so that the positioning block 1002 contacts the placement hole 1006, and cooperates with the positioning hole 505 to position the sliding rod 502, thereby maintaining the stability of the positioning of the protruding rod 3.
