If the distance between the first sleeper and the second sleeper is greater than the preset distance, the driving member is reversed, the bidirectional screw 1 is reversed synchronously, and the two moving plates 2 move away from each other, driving the two sleeper clamps 5 to move towards each other. The position of the first sleeper remains unchanged, and the second sleeper moves towards the first sleeper under the driving of the sleeper clamps 5. The distance display on the distance positioning member 8 is observed. If the distance displayed on the distance positioning member 8 reaches the preset distance, the distance between the first sleeper and the second sleeper reaches the preset distance, and the distance between the first sleeper and the second sleeper is adjusted by the preset distance. Then the driving member stops working, and the distance adjustment between the first sleeper and the second sleeper is completed. The second sleeper is fastened to the rail by a bolt. If the distance between the first sleeper and the second sleeper is less than the preset distance, the driving member rotates in the forward direction, the bidirectional screw 1 rotates in the forward direction synchronously, and the two moving plates 2 move towards each other, driving the two sleeper clamps 5 to move away from each other. The position of the first sleeper remains unchanged, and the second sleeper moves away from the first sleeper under the driving of the sleeper clamps 5. The distance display on the distance positioning member 8 is observed. If the distance displayed on the distance positioning member 8 reaches the preset distance, the driving member stops working, and the distance adjustment between the first sleeper and the second sleeper is completed.
