The invention has the following remarkable beneficial effects:

1. the starting rod is moved downwards, the pressure sleeve is pressed downwards by the starting rod, the pressure sleeve and the suction disc are communicated in a sealing mode, so that the pressure inside the pressure sleeve and the pressure inside the suction disc are increased, after the pressure is increased, the elastic film is extruded by air, and the elastic film is in contact with the road surface due to elastic deformation of the elastic film, so that a closed space is formed among the elastic film, the suction disc and the ground, and the sealing performance between the suction disc and the road surface is enhanced;

continuing to move the starting rod downwards, driving the suction disc to move downwards by the starting rod, discharging air among the elastic film, the suction disc and the ground, and sucking the suction disc on the road surface;

the actuating rod is only required to be moved to trigger a series of parts, so that the suction disc is quickly and stably sucked on the road surface.

2. The supporting rod is used for strengthening the supporting effect of the supporting tube.

3. The air is replaced by oil, and the oil has poor volatility, so the service life is long.

4. When the starting rod is moved, the starting rod can be moved downwards in a labor-saving manner only by moving the switch rod downwards, and after the suction disc is sucked to the road surface, the stop rod is rotated to clamp the switch rod, so that the starting rod is fixed, and the suction disc keeps suction.

5. Because a plurality of safety protection devices are needed in actual work, two adjacent safety protection devices can be fixedly connected with a matching piece through the clamping piece, and the fixing effect of the safety protection devices can be enhanced.

6. The manual downward movement of the starting rod is replaced by the downward movement of the permanent magnetic chuck, and the magnetic property of the permanent magnetic chuck is opposite to that of the magnetic force column, so that the starting rod can be pushed to move downwards for a short distance, and the device can be quickly and conveniently fixed on the road surface.

7. When the baffle is changed into cotton cloth, the invention can be rolled up when being dismantled, so that the occupied space of the invention is reduced, the transportation is more convenient, and the working efficiency is enhanced.

8. After the cotton cloth is impacted, the softness of the cotton cloth can reduce the damage to pedestrians; the shear thickening liquid in the filling pipe can be quickly changed into solid to resist the impact force of pedestrians.
