As a result, when the anti-collision plate is impacted, the device cannot effectively slow down or alleviate external impact or vibration force. Therefore, a car swing arm with a stable structure is needed to improve the above problem. Utility Model Content

[0046] Among them, the plug-in block 302 will be plugged into the sliding groove 402. Since the top surface of the snap-in block 405 is designed to be arc-shaped, when the plug-in block 302 moves downward, the snap-in block 405 will be squeezed to compress the first spring 407. When the snap-in block 405 is aligned with the plug-in groove 303, the snap-in block 405 will be quickly snapped into the plug-in groove 303 under the action of the first spring 407, thereby achieving the benefit of quickly installing the protective component 3 on the device.

Under the action of the third spring 509, the positioning block 507 will be snapped into the limiting groove 304 to realize the positioning of the threaded rod 506. When the two limiting grooves 304 on the anti-collision plate 301 are inserted into the two positioning blocks 507, the two positioning blocks 507 will limit the positions of the anti-collision plate 301 and the threaded rod 506, thereby maintaining the integrity between the mounting ring 2, the buffer assembly 5 and the protection assembly 3;

[0050] At the same time, the plug-in block 302 will be plugged into the sliding groove 402. Since the top surface of the snap-in block 405 is designed to be arc-shaped, when the plug-in block 302 moves downward, the snap-in block 405 will be squeezed to compress the first spring 407. When the snap-in block 405 is aligned with the plug-in groove 303, the snap-in block 405 will be snap-fitted into the plug-in groove 303 under the action of the first spring 407, thereby achieving the benefit of quickly installing the protective component 3 on the device.
