[0002] At present, during the construction of roads and bridges, it is necessary to set up formwork for structures cast in concrete. When setting up the formwork, tie rods are used to fix the inner and outer formworks. The traditional structure reserves holes on the inner and outer formworks respectively, passes one end of the tie rod through the two holes in turn, and then tightens it with a nut, thereby achieving a fixing effect between the formworks and preventing the formworks from loosening and falling off during the pouring process.

[0003] Patent No. CN218147823U discloses a pair of tie rods for fixing formwork in road and bridge construction. The device can fix formworks at different intervals by setting up a first tie rod, a second tie rod and a connecting pipe for use in combination, which not only saves time and effort but also ensures fixing efficiency. However, the width of the limit assembly cannot be adjusted in the above patent, resulting in the inability to adapt to formworks of different sizes, thereby affecting the construction efficiency.
