The shape of the first sphere 5 is adapted to the shape of the second sphere 9.

[0026] The working principle of the utility model is:

[0027] When the radar body 1 needs to be installed, the radar body 1 is moved. When the radar body 1 moves to a certain position, the first sphere 5 and the two second spheres 9 are squeezed. Under the action of the first sphere 5, the two second spheres 9 move to both ends along the sliding sleeve through the two moving rods 8 and the two first springs 11. Then the first sphere 5 continues to move. When the first sphere 5 and the two second spheres 9 are released from squeezing, the two second spheres 9 are restored under the action of the elastic force of the first springs 11, and the first sphere 5 can be fixed, thereby fixing the mounting frame 2 and the mounting box 6, and then fixing the radar body 1. When the radar body 1 needs to be disassembled, the connecting plate 14 and the pull rod 13 are pulled, and the movement of the pull rod 13 drives the moving rod 8 and the second sphere 9 to move, and the first sphere 5 can be released. The radar body 1 is restricted by the body 5, and then the radar body 1 can be disassembled by moving. When the two sides of the radar body 1 are squeezed or impacted, the object will first contact the protective plate 1202. When the object contacts the protective plate 1202, it will squeeze the protective plate 1202, thereby driving the protective plate 1202 to move. Since the first connecting seat 1203, the second connecting seat 1205 and the connecting frame 1204 are hinged to each other, when the protective plate 1202 squeezes the first connecting seat 1203, the two fixed plates 1206 are driven to approach each other through the connecting frame 1204 and the second connecting seat 1205, thereby squeezing the second spring 1209, causing the second spring 1209 to contract. The contraction process of the second spring 1209 can buffer the protective plate 1202, thereby achieving a protective effect.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
