3. The limiting compression springs arranged at the two ends of the connecting shaft are mainly used for limiting the displacement change of the comb tooth gaps in the transverse movement, namely the width direction of the bridge deck.

4. Stop device below broach owner toothed plate, the steel backing plate and the tetrafluoro plate of button head bolt nut upper cover, with the flexible restriction of broach in the guide way within range, guarantee simultaneously to stride seam main part expansion gear board and can not rise and fall by a wide margin when leading to the car, play limiting displacement, avoid striding seam owner tooth flexible when the vehicle is current in-process to cause the telescopic system motion asynchronous, make the flexible volume of broach seam be in reasonable within range simultaneously.

5. The large inclined angle comb teeth on the main comb tooth plate and the auxiliary comb tooth plate can automatically clean the garbage in the comb tooth seams when the comb teeth stretch out and draw back, prevent the garbage from not being cleaned in time and influencing the energy accumulated by the bridge stretching displacement from being effectively released, damage to the stretching device and the bridge, potential safety hazards and traffic accidents,

this kind of novel three-dimensional diversified diversion broach telescoping device, than ordinary single function broach seam possess better shock resistance durability, the more efficient strength release function that freely stretches out and draws back to and longer bridge life and guarantee vehicle driving safety.
