Wherein, the chest of drawers 100 can be clamped to the trunk 300 by a clamp (not shown) and located under the workbench 400 for use by users. The lock 44 of the chest of drawers 100 can pass through the workbench 400 and be exposed on the top surface of the workbench 400, so that the user can manipulate the lock 44 (such as: insert a key into the lock hole on the top of the lock 44) To control the modular locking device 4 to be in the locked position or the unlocked position. Furthermore, the above-mentioned trunk 300 above the chest of drawers 100 can be used to mount a screen or other medical devices (not shown in the figure).

It should be added that the above-mentioned drawers 21, 21' are described in terms of external dimensions, but each drawer 21, 21' itself can also be divided into multiple smaller compartments according to design requirements (as shown in Fig. 10).

To sum up, the modular locking device of the embodiment of the present invention can be applied to frames of different heights or drawers of different sizes through the combination of rotating parts. In other words, the user can assemble the frames according to different heights into various configurations required by the user, thereby achieving the effect of reducing costs.
