Component No. 1, the component No. 1 includes a column, a driving rod is passed through the interior of the column from top to bottom, a cross handle is installed above the driving rod, a worm is arranged below the driving rod, a worm wheel is meshed with the outer wall of the worm, a nut pair is connected to the inner wall of the worm wheel, a screw is arranged inside the nut pair, and a block is connected to one end of the screw.

Preferably, the second component includes a fixing plate, a damping spring and a guide groove are installed on one side of the fixing plate, a guide rod is inserted into the inside of the guide groove, and a mounting plate is installed on the end of the guide rod away from the guide groove.

Preferably, the column is provided with a hole corresponding to the driving rod, and the worm gear is fixedly connected to the nut pair.

Preferably, the cross handle is fixedly connected to the driving rod, and the upright column is provided with a hole corresponding to the block.

Preferably, the screw rod is fixedly connected to the block, and the fixing plate is fixedly connected to the column.

Preferably, two ends of the damping spring are fixedly connected to the fixing plate and the mounting plate respectively, and the guide groove is fixedly connected to the fixing plate.

Preferably, the guide rod is slidably connected to the guide groove, and the guide rod is fixedly connected to the mounting plate.

Compared with the prior art, the beneficial effects of the utility model are:

Through the setting of component No. 1, the new safety fence can first cast an inverted "T"-shaped groove with concrete, insert the column into the groove, and turn the cross handle. The cross handle drives the driving rod to rotate, the driving rod drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the nut pair to rotate, the nut pair rotates the lead screw to move toward the outside of the column, and the lead screw drives the block to move toward the outside of the column, so that the block is stuck in the groove to fix the position of the column. During subsequent disassembly, replacement and maintenance, the cross handle can be rotated in the opposite direction to pull the column out of the inverted "T"-shaped groove. The operation is simple and quick, which saves a lot of time and reduces labor intensity.

This new type of safety fence is equipped with component No. 2. When a car deviates from its route and hits the mounting plate, the shock-absorbing spring will dissipate energy and reduce vibration. Under the action of the shock-absorbing spring, the impact force of the car on the safety fence is reduced, thus avoiding large-scale damage to the car. The guide rods and guide grooves play a guiding and supporting role.
