A plurality of intermediate magnetic blocks 204 are provided between the first magnetic block 203 and the second magnetic block 206. When the motorcycle vibrates during driving, the telescopic rod 202 will slide in the mounting rod. Due to the repulsive effect between the magnetic blocks, the motorcycle will have a good buffering effect. At the same time, since the action range between the magnets is relatively small, the telescopic rod 202 can have a good buffering effect within a smaller sliding range. When the telescopic rod 202 slides back, the air between the end of the telescopic rod 202 and the outer shell 1 will be compressed, thereby generating a damping effect, making the telescopic rod 202 slide back more slowly, thereby achieving a buffering and shock-absorbing effect for the driving of the motorcycle. On the other hand, for different In order to meet the driving needs, the user can change the buffering effect of the device by adding different numbers of intermediate magnetic blocks 204 between the first magnetic block 203 and the second magnetic block 206.

When the connecting head 201 needs to be removed, the user can adjust the position of the fixing seat 205 by rotating the driving screw 209. When the fixing seat 205 moves to conflict with the connecting head 201, the two sides of the fixing seat 205 will push the locking block 501 through the hemispherical ends on the side of the locking block 501, so that the locking block 501 slides and releases the locking state with the connecting slider 505. At this time, the connecting head 201 can be removed, which is convenient for operation.

When the sliding sleeve 401 moves to the inner positioning hole 405 and is aligned with the corresponding positioning column 406, the positioning column 406 will be embedded in the positioning hole 405 to fix the current position of the sliding sleeve 401. The buffer spring 402 connected between the end of the sliding sleeve 401 and the telescopic rod 202 can not only provide additional buffering effect for the device, but also adjust the shock absorption effect of the telescopic rod 202 during the return process, so that the use of the device is more flexible. At the same time, when the sliding sleeve 401 needs to be adjusted, the user only needs to press the release block 404 to release the engagement state between the positioning column 406 and the positioning hole 405, which is convenient for operation.

[0024] When the present invention is in use, first, a telescopic rod 202 is slidably connected in the outer shell 1, a first magnetic block 203 is fixed at the end of the telescopic rod 202, and a second magnetic block 206 fixed in a fixing seat 205 is provided on a connector 201 located at the rear end of the outer shell 1, and a plurality of intermediate magnetic blocks 204 are provided between the first magnetic block 203 and the second magnetic block 206. When the motorcycle vibrates during driving, the telescopic rod 202 will slide in the mounting rod, and due to the repulsive effect between the magnetic blocks, the motorcycle will have a good buffering effect. At the same time, since the action range between the magnets is relatively small, the telescopic rod 202 can have a good buffering effect within a smaller sliding range. When the telescopic rod 202 slides back, due to the contact between the end of the telescopic rod 202 and the outer shell 1, The air between the two ends of the telescopic rod 202 will be compressed, thereby generating a damping effect, making the sliding back of the telescopic rod 202 more gentle, thereby achieving a buffering and shock-absorbing effect for the motorcycle.

When the fixing seat 205 moves to conflict with the connecting head 201, the two sides of the fixing seat 205 will push the locking block 501 through the hemispherical ends of the side of the locking block 501, so that the locking block 501 slides and releases the locking state with the connecting slider 505. At this time, the connecting head 201 can be removed for easy operation. In order to facilitate the rotation of the first gear 207 to adjust the position of the fixing seat 205 and achieve the adjustment of the buffering effect, the mounting head 301 located on the connecting head 201 is used to connect and fix with the motorcycle.
