The right end of the rack 8 is not in contact with the sealing plate 102 in a natural state that the second spring 105 is not compressed, and the second spring 105 and the first spring 104 are in a natural state, the number of turns of the second spring 105 is larger than the number of turns of the first spring 104 in the same length, and the diameter of the spring wire of the second spring 105 is also larger than the diameter of the spring wire of the first spring 104, so that it is obvious that the stiffness coefficient of the second spring 105 is larger than that of the first spring 104, as shown in fig. 5, when the rack 8 is pushed to the right, the second spring 105 can push against the sleeve rod 103 to move under the condition of incomplete compression, and therefore, the rack 8 cannot be in contact with the sealing plate 102 on the premise that the sleeve rod 103 still has a moving space.

The working principle and the using process are as follows:

firstly, fixing a gasket 2 and a cushion 5 on the top of a sleeper 1, clamping a rail 17 between fixture blocks 21, in an initial state, rotating a rotating column 6 to buckle a sleeve buckle 61 at the end part of the rotating column 6 to a curved buckle 151, in the rotating process of the rotating column 6, a gear 7 is meshed with a toothed rod 8, so that the toothed rod 8 extends into an inner cavity of a first oil cylinder 9 to push a double-pass piston 10, when the double-pass piston 10 is pushed, a piston rod of the double-pass piston 10 pushes a sliding frame 3 positioned on one side of the rail 17 to slide, an oil cavity space of the first oil cylinder 9 positioned on the right side of the double-pass piston 10 is reduced, so that hydraulic oil is pressed into a second oil cylinder 12 along an oil guide pipe 13 to push a piston rod of the second oil cylinder 12 to move, the piston rod of the second oil cylinder 12 drives the sliding frame 3 positioned on the right side of the rail 17 to slide to the rail 17, and finally, the fastener 4 on both sides are contacted with the fixture blocks 21, and rotates to finally press the bottom of the track 17 to fix the track 17;

if the sleeve buckle 61 of the rotating column 6 is not buckled with the arc buckle 151 at the moment and needs to continue rotating, the toothed bar 8 still provides thrust for the two-way piston 10, so that the second spring 105 is compressed, the two-way piston 10 is not moved until the right end of the toothed bar 8 props against the sealing plate 102, and the sealing plate 102 can re-block the unsealing piston 101 due to the thrust of the toothed bar 8;

when the sliding frame 3 needs to be contacted with the rail 17 for fixing, the clamping piece 15 is pulled, the arc-shaped buckle 151 and the sleeve buckle 61 are released, the rotating column 6 is lifted, the rotating column 6 rotates, the gear 7 drives the rack bar 8 to retreat, the two-way piston 10 retreats, the blocking block 1014 is separated from blocking the opening at the left end of the second through hole 1017 due to the oil pressure effect at the left side of the two-way piston 10, the hydraulic oil at the left side of the two-way piston 10 enters the right side of the two-way piston 10 through the second through hole 1017, the hydraulic oil in the second oil cylinder 12 can flow back to the first oil cylinder 9 along the oil guide pipe 13, and the sliding frame 3 retreats the fastening piece 4 to be separated from the rail 17 in the process, so that the fixing is released.
