[0024] When the connecting column 6 at one end of the traction sleeve 5 penetrates into the slot 4, the traction sleeve 5 is rotated to move the connecting column 6 toward the bottom of the slot 4. At this time, the side of the connecting column 6 squeezes the pressure plate 8 to shrink the multiple compression springs 9, and then the traction sleeve 5 is released. Under the rebound force of the multiple compression springs 9, the pressure plate 8 is driven to squeeze the outside of the connecting column 6, so that the connecting column 6 is fixed at the bottom of the slot 4, completing the connection between the traction sleeve 5 and the fixed sleeve 2.
