The invention relates to a channel clearing and collateral activating
massage bed with a spine protection function, which comprises a
bed frame, a
bed surface, a sliding block, an elastic supporting plate, a traction
rope, a movable rod, a self-
rotating disc and a movable plate, and a switching
assembly comprises a first rotating shaft rotationally connected with the edge of the self-
rotating disc, a second rotating shaft movably matched with the self-
rotating disc and a rotating plate. The
threaded rod is manually rotated to drive the rectangular rod and the connecting plate to drive the rotating plate connected with the second rotating shaft to generate angle change, so that the first rotating shaft and the second rotating shaft at the eccentric point of the rotating disc are driven to get close to each other or get away from each other. When the first rotating shaft and the second rotating shaft get close to each other, the two sliding blocks move in the same direction in cooperation with the movable plate, and therefore movement of the position of the elastic supporting plate is achieved; when the first rotating shaft and the second rotating shaft are far away from each other, the two sliding blocks move close to each other or far away from each other, so that the arching
radian of the elastic supporting plate is changed, and switching between a position adjusting mode and a
radian adjusting mode is achieved.
