The cross section is a plane perpendicular to the first direction (ie, direction A in the figure). The guide groove 23 can also restrict the guide rail 313 from detaching from the guide groove 23 in a direction perpendicular to the first direction (ie, direction A in the figure).

In this way, the sliding connection between the second buffer block 2 and the buffer bracket 3 in the first direction (that is, the direction A in the figure) can be realized through the guide groove 23 and the guide rail 313, and it can also be connected along the first direction (that is, the direction A in the figure). When the position of the second buffer block 2 is adjusted in the direction A), the second buffer block 2 is restricted from the guide groove 23 in a direction perpendicular to the first direction (that is, the direction A in the figure) by the guide chute 23, for example, the second buffer block 2 can be prevented. The second buffer block 2 turns over relative to the buffer bracket 3 and breaks away from the buffer bracket 3 .

In this way, when the limiting rib 24 is placed in the limiting groove 314, and the second buffer block 2 and the buffer bracket 3 are in the state of being fastened by the fastening connection structure, the gap between the limiting rib 24 and the limiting groove 314 The limit can enhance the relative position holding force between the second buffer block 2 and the buffer bracket 3 along the first direction (that is, the direction A in the figure), and can improve the stability of the position. Moreover, in some cases, by rationally designing the depth and cross-sectional shape of the limiting groove 314, when the impact of the second buffer block 2 is too large due to collision or other reasons, the limiting rib 24 can be adjusted from the matching limiting rib 24 The groove 314 comes out and snaps into another limiting groove 314, and the impact caused by the collision can be alleviated by the movement of the second buffer block 2 along the first direction (ie, the A direction in the figure). For example, the depth of the limiting groove 314 is 0.5 -2.5 mm, such as 1-1.5 mm, the cross-sectional shape of the limiting groove 314 is semicircular, and its two ends along the first direction (that is, the direction A in the figure) are smoothly transitioned and connected.

At this time, the limiting rib 24 is located outside the limiting groove 314, and the second buffer block 2 and the buffer bracket 3 The relative position retention force is relatively small, but the height of the second buffer block 2 relative to the bottom of the limiting groove 314 is relatively high. It can move along the first direction (that is, the A direction in the figure), so that the limiting rib 24 enters the adjacent limiting groove 314, and the impact is first buffered by the movement of the second buffer block 2, and then the limiting rib 24 and the limiting rib 24 are connected to each other. The position limiting of the position groove 314 realizes the relative position fixation of the two again, which has a simple structure and strong practicability.

In the above-mentioned embodiment, besides the slope structure 22, the end of the second buffer block body 21 close to the first buffer block 1 can also be provided with a back support slope opposite to the slope direction of the slope structure 22. Between the slope structure 22 and the back support slope In this way, the contact area between the second buffer block 2 and the fixed block 31 can be increased through the corresponding part of the back support slope, without increasing the coverage of the slope structure 22, and avoiding the second buffer block 2 When moving along the first direction, the slope structure 22 interferes with the first buffer block 1 .
