As shown in fig. 18, when the user pulls the handle 42 of the handle assembly 4, the arc-shaped driving arc 421 at the head of the handle 42 drives the driving sector 435 of the driving ring head 43, so that the driving square shaft 433 drives the linkage gear 46 to rotate. Then, the interlocking gear 46 takes the tab tooth 333 of the driving tooth block 33, so that the driving tooth block 33 descends, as indicated by F1 in fig. 18. Then, the linkage wire 34 simultaneously pulls the linkage block 341, the linkage block 342, the linkage block 343, the linkage block 344, and the linkage block 345, so that the five linkage blocks respectively move along the directions K1, K2, K3, K4, and K5, so that the locking posts 3412 on the linkage blocks 341, 342,343,344, and 345 are simultaneously disengaged from the corresponding locking hooks 22, and then the linkage blocks corresponding to the locking hooks 22 are unlocked. For the same reason, the other of the two wire drive systems S is unlocked in the same manner. Finally, all the linkage blocks are unlocked, and the user grasps the handle 42 to take down the whole cabinet door assembly 3, thereby completing the disassembly of the cabinet door.

When the cabinet door needs to be installed, the cabinet door assembly 3 is buckled on the frame assembly 2 again, then the handle 42 is rotated again, and all the linkage blocks can be locked again by the same principle.

Obviously, in the unlocking process, a user must operate with both hands to unlock all the linkage blocks. In the locking process, a user can operate with one hand, firstly, one of the two groups of steel wire driving systems S is started, and half of the linkage blocks are locked. Then, another group of steel wire driving systems S is started, and the rest half of linkage blocks are locked, so that the operation is convenient and fast.

Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
