In this embodiment, as shown in the figure, a spring is disposed in the buffer cylinder 3, and two ends of the spring are connected to the connecting rod 4 and the buffer cylinder 3 respectively.

In this embodiment, as shown in the figure, the angle range of the rotation of the mounting plate 2 relative to the buffering device is 0-90 degrees.

In the embodiment, as shown in the figure, the mounting plate 2 is provided with a first mounting hole 6 and a second mounting hole 7; the first mounting hole 6 and the second mounting hole 7 are both located at one end of the mounting plate 2 far away from the fixing and adjusting device.
