In the present utility model, by providing a quick positioning component, when the plug block on the second power rail trolley is inserted into the card slot on the first power rail trolley, the outer shell on the outer wall of the plug block is also inserted into the positioning slot. The inner wall of the positioning slot first squeezes the second pin to form a compressed state, and the second pin displaces. The second pin drives the second pressing plate to displace. The second pressing plate squeezes both ends of the second spring to produce a compressed state. At this time, the second pin retracts into the interior of the outer shell. When the second pin and the positioning hole provided on the inner wall of the positioning slot are on the same horizontal line, due to the elastic force of the second spring, the second pin is pushed out of the interior of the outer shell and inserted into the positioning hole. Through this design, when effectively splicing the first power rail trolley and the second power rail trolley, it enables the first pin and the internal thread pin to be precisely on the same horizontal line as the jacks, greatly improving the splicing efficiency and having good use effects.
