The internal sliding connection of the upper support plate 600 is provided with two limit rods 605, and the limit rods 605 are made of iron material. The lower support plate 601 is symmetrically provided with two limit grooves 602 at one end close to the upper support plate 600, and the The interior of the lower support plate 601 is also symmetrically fixed with two magnet blocks 603. When the upper support plate 600 and the lower support plate 601 are aligned with each other, the limiting rod 605 will be adsorbed into the limiting groove 602 under the action of the magnet block 603, so that the upper support plate 600 and the lower support plate 601 are locked in this way, and then the radar probe 2 is limited.

[0028] When the utility model is used, when a vehicle collides with another, the radar probe 2 will move quickly into the protective tube 1 under the action of inertia or when the radar probe 2 directly contacts the collision object. The radar probe 2 will squeeze the pushing ball 608 during the movement. When the pushing ball 608 is squeezed, it will push the pushing plate 607, so that the pushing plate 607 drives the limiting rod 605 to disengage from the limiting groove 602, thereby separating the upper support plate 600 from the lower support plate 601. After the upper support plate 600 is separated from the lower support plate 601, the radar probe 2 will quickly enter the protective tube 1 under the action of the pulling spring 7, thereby preventing the radar probe 2 from being damaged by the impact.
