[0041] In this embodiment, when adjusting the position of the buffer block 40, the rotary knob 30 is rotated around the axis of the connecting rod 50, and through the cooperation between the screw rod 60 and the rotary knob 30, the screw rod 60 is driven to reciprocate up and down along the axis of the connecting rod 50, so that the buffer block 40 can adjust its position according to the spacing gap between the vehicle tailgate and the vehicle body, avoiding that the buffer block 40 cannot play a buffering effect when the vehicle tailgate is closed on the vehicle body. Through the above buffer block 40 whose position can be adjusted, it can adjust its position according to different spacings, improving the overall adaptability and greatly enhancing the overall practicality.
[0042] Specifically, two groups of elastic plates 51 are arranged on the outer wall of the connecting rod 50, and the two groups of elastic plates 51 are symmetrically arranged;
