[0029] Working principle:

[0030] When the first bushing 310 needs to be installed, the mounting rod 305 is inserted into the connecting seat 301, and the mounting rod 305 extrudes the elastic plates 303 in the process of insertion, so that the elastic plates 303 are expanded outward by the rotating rod 304 and the coil spring, so that the mounting rod 305 can be completely inserted into the connecting seat 301, and the mounting rod 305 extrudes the clamping block 307 in the process of insertion, so that the clamping block 307 extrudes the rotating shaft 308, so that the rotating shaft 308 stretches the first spring 5, when the mounting rod 305 is inserted, the elastic plates 303 are reset under the action of the elastic force of the coil spring, and the rotating shaft 308 is reset under the action of the elastic force of the first spring 5, and the elastic plates 303 are close to the mounting rod 305 in the process of resetting, so that the clamping block 307 is inserted into the clamping groove 306 formed in the mounting rod 305, then the rotating shaft 308 is rotated, so that the rotating shaft 308 drives the arc-shaped elastic piece 309 to rotate, the inner wall of the clamping groove 306 is abutted by the arc-shaped elastic piece 309, and the friction between the arc-shaped elastic piece 309 and the inner wall of the clamping groove 306 can also be increased, so that the mounting rod 305 and the connecting seat 301 are fixed, when disassembling, the rotating shaft 308 is rotated, so that the arc-shaped elastic piece 309 is separated from the inner wall of the clamping groove 306, then the elastic plates 303 are outwardly bent, and the mounting rod 305 can be taken out from the connecting seat 301

[0031] When the vehicle vibrates, the impact force extrudes the first bushing 310, so that the first bushing 310 extrudes the damping rod 202 through the mounting rod 305 and the connecting seat 301, so that the damping rod 202 slides along the sleeve 201, so as to drive the second spring 204 to contract through the tray 203, and the resistance of the viscous liquid in the sleeve 201 and the elastic force of the second spring 204 are balanced, so as to achieve the effect of buffering and damping.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
