[0028] As shown in FIG. 10, the clothes drying support frame at the upper left side may also be rotated to a 30° upwards inclined position according to requirements, so that the clothes drying support frame positioned at the upper left side drives the third connecting disc in the corresponding angle adjusting mechanism to rotate to a third position, the second locking hole rotates to a position right against the corresponding locking block, the knob rotates in an anticlockwise direction to drive the arc-shaped guide strips to anticlockwise rotate to a fifth position by taking the rotating shaft as a circle center, the sliding block in the locking block outwards moves along the guide surface, the connecting block and the limiting block are driven to outwards move, the limiting block extends out of the corresponding first arc-shaped limiting hole, and the front end of the limiting block is inserted into the first locking hole in the third connecting disc when they are in the first position to lock the third connecting disc.

[0029] As shown in FIG. 11, the clothes drying support frame at the upper right side may be rotated to a 30° upwards inclined position according to requirements, so that the clothes drying support frame positioned at the upper right side drives the fourth connecting disc in the corresponding angle adjusting mechanism to rotate to a fourth position, the fourth connecting disc rotates to drive the locking surface to rotate to a position right against the corresponding locking block, the knob is continuously rotated anticlockwise so that the knob drives the arc-shaped guide strips to anticlockwise rotate to a sixth position by taking the rotating shaft as a circle center, the arc-shaped guide strips drive the corresponding locking block to continuously extend out, and the limiting block in the locking block is abutted against the corresponding locking surface to lock the fourth connecting disc.

[0031] When the unfolded clothes drying rack needs to be folded, the knob is clockwise rotated so that the locking block slides along the guide surface of the corresponding arc-shaped guide strip, the locking block retracts back into the corresponding first arc-shaped limiting hole, at this time, the third connecting disc is unlocked from the fourth connecting disc, the two clothes drying support frames positioned at the upper side may rotate to reach a stored state, next, the two clothes drying support frames positioned at the lower side are inwards rotated, and the first connecting disc and the second connecting disc are rotated to a stored position.

[0032] When the knob rotates, opposite acting force exerted on the knob when the sliding block in the locking block is in contact with the first guide surface, the third guide surface, and the fifth guide surface which are vertically arranged is smaller than opposite acting force exerted on the knob when the sliding block is in contact with the second guide surface and the fourth guide surface which are vertically arranged. Therefore, a user may conveniently distinguish the current angle gear of the angle adjusting mechanism through the knob rotating resistance.
