Continue to pull the handle 12 outward, the driver 10 drives the latch 20 so that the latch 28 breaks away from the fastening hole 202 of the frame 200 and retracts into the receiving member 40, at this time, the spring 60 is Stretching and deforming, at the same time, the locking member 20 drives the supporting member 30 to rotate and deforms the torsion spring 70 under pressure, and the handle 12 is further pulled outward, so that the functional module 100 can be taken out. After the functional module 100 is taken out, the handle 12 is released, and the spring 60 recovers to deform, so that the driving member 10 moves toward the receiving member 40 to reset, the torsion spring 70 recovers to deform, and the first torsion arm 72 pushes The support member 30 rotates to reset the locking member 20 and make the locking portion 28 protrude from the receiving member 40 , which is convenient for installing the functional module 100 next time.

在上述实施方式中，该扭簧70的作用是使该支撑件30转动而复位，可以理解，在另一实施方式中，可以使用其他弹性元件取代该扭簧70以实现该支撑件30的复位，例如，一两端分别设有扣钩的弹簧，其一端钩扣于该收容件40的第二侧壁43，其另一端钩扣于该支撑件30的第一端(靠近该锁扣件20的一端)。当该锁扣件20连动该支撑件30转动时，连接于该收容件40的第二侧壁43与该支撑件30之间的弹簧受拉变形。该弹簧恢复变形使该支撑件30转动而复位。In the above embodiment, the function of the torsion spring 70 is to make the supporting member 30 rotate and reset. It can be understood that in another embodiment, other elastic elements can be used instead of the torsion spring 70 to realize the resetting of the supporting member 30. For example, one two ends are respectively provided with the spring of buckle, and its one end is hooked on the second side wall 43 of this accommodating part 40, and its other end is hooked on the first end of this support member 30 (near this locking part 20 end). When the locking member 20 rotates in conjunction with the supporting member 30 , the spring connected between the second side wall 43 of the receiving member 40 and the supporting member 30 is stretched and deformed. The spring recovers and deforms so that the support member 30 rotates and resets.

综上所述，本发明锁扣装置的较佳实施方式使该功能模块100的装卸过程无需螺丝及其他工具，并且在抽取过程中，仅需一手拉动该手柄12便可完成解锁及将该功能模块100抽取出来，操作过程方便、快捷。To sum up, the preferred implementation of the locking device of the present invention eliminates the need for screws and other tools during the assembly and disassembly process of the functional module 100, and during the extraction process, only one hand is needed to pull the handle 12 to complete the unlocking and the function The module 100 is extracted, and the operation process is convenient and fast.
