The friction cylinder 50 in the damping assembly 49 is less affected by factors such as temperature and environment, the damping effect is stable, and the damping force is simple to preset. The damping adjustment cylinder 52 is provided with an adjustment channel 58 and a second damping adjustment gap 59 extending along the axial direction, the friction cylinder 50 is mounted on the adjustment channel 58, an installation space is provided for the friction cylinder 50 through the adjustment channel 58, and the friction cylinder 50 is provided with the first damping adjustment gap 51 because the friction cylinder 50 is mounted in the adjustment channel 58, so that the width of the first damping gap A is reduced, the holding force of the inner wall of the friction cylinder 50 on the damping transmission rod 22 is increased, and the damping effect on the damping transmission rod 22 is further increased. Because the friction cylinder 50 is positioned in the damping adjustment cylinder 52, the second damping adjustment gap 59 penetrates through two ends of the damping adjustment cylinder 52 along the axial direction, the second damping adjustment gap 59 is communicated with the adjustment channel 58, two ends of the adjusting piece 60 are respectively positioned on two opposite sides of the second damping adjustment gap 59 and are connected with the damping adjustment cylinder 52, the width of the second damping adjustment gap 59 is further adjusted by the adjusting piece 60, the installation space of the damping channel is reduced, the friction cylinder 50 is further extruded by the damping adjustment cylinder 52, the width of the first damping gap A is reduced on the basis of the initial width, and further, the damping action is generated on the damping transmission rod 22, the damping action is adjusted through the adjusting piece 60, the damping action is adjusted only through operating the adjusting piece 60, and the damping adjustment operation is simple and quick.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present utility model, and these modifications and substitutions should also be considered as being within the scope of the present utility model.
