[0020] II. Assembly process of A-shaped folding clothes hanger:

[0021] Step 1: Fix the semicircular non-recess surface at the two lateral ends of the cross diagonal symmetry connector with the semicircular recess at one end of the main support rod using a short screw and a nut.

[0022] Step 2: Fix the semicircular recess at the two longitudinal ends of the cross diagonal symmetry connector with the semicircular recess at one end of the auxiliary support rod using a short screw and a nut.

[0023] Step 3: Fix the middle part of the hanging rod with the middle part of the main support rod and the auxiliary support rod using a long screw and a nut.

[0025] Step 5: Insert one end of the lock pin cylindrical lock core into the pin hole in the middle part of the main support rod, align the long straight recess on the cylindrical lock core with the lock pin screw hole, and screw the lock pin screw into the lock pin screw hole so that the lock pin screw is inserted into the long straight recess.

[0026] III. Introduction to folding principle

[0027] (1) When the cross-folded folding clothes hanger is unfolded, push the handle at one end of the lock pin inward, so that the cylindrical lock core at one end of the lock pin protrudes from the lock pin hole in the middle part of the main support rod and clamps the hanging rod, preventing the hanging rod from being folded downward.

[0028] (2) When the crosswise folding drying rack is folded, pull the handle of the lock pin to the outside, so that the cylindrical lock core of the lock pin is completely retracted into the lock pin hole in the middle of the main support rod. The hanging rod starts to fold downward. When the crosswise folding drying rack is completely folded, then push the handle of the lock pin to the inside, so that the cylindrical lock core of the lock pin is inserted into the lock pin hole in the middle of the hanging rod, locking the hanging rod from moving.

Claims
