[0010] Furthermore, the outer wall of the connecting rod and the inner wall of the adjusting tube are in contact with each other.

[0011] Furthermore, the position of the threaded hole corresponds to the position of the threaded groove.

[0012] The beneficial effects of the buffer overhead guard connection assembly of the utility model are as follows: the adjustment tube, the connection device and the support rod can cooperate to adjust the height of the overhead guard to meet different usage needs; the overhead guard is fixed by the support rod and the top of the overhead guard can be disassembled for easy later maintenance; the top plate, the guide rod, the buffer spring, the guide hole and the overhead guard plate form a buffer part, which can buffer the impact force of the goods and reduce damage; the limit device can fix the overhead guard plate to prevent the vibration generated during operation from shaking the overhead guard off; after removing the limit device, the overhead guard plate can be removed upward from the limit rod, so that the buffer spring can be maintained and replaced, avoiding damage to the buffer spring caused by long-term use and reducing the replacement cost at the same time.
