When the second valve body 23 is in the air release state, the soft and hard adjusting device 4 is communicated with the air inlet 11 of the air source 1 through the second valve body 23, so that the soft and hard adjusting device 4 is contracted and deformed under the action of negative pressure, and the hardness of the soft and hard adjusting device 4 is increased, when the second valve body 23 is in the air inflation state, the soft and hard adjusting device 4 is communicated with the external environment or the air inlet 11 of the air source 1 through the second valve body 23, so that the soft and hard adjusting device 4 is recovered and deformed under the action of normal pressure or positive pressure, and the hardness of the soft and hard adjusting device 4 is reduced, when the second valve body 23 is in the pressure maintaining state, the soft and hard adjusting device 4 enters the pressure maintaining mode, and the hardness of the soft and hard adjusting device 4 is kept unchanged.
