At the same time, the shoulder portion 162 of the connecting portion 16 of the driving member 10 corresponds to the convex portion 26 on both sides of the locking member 20, which The first end of the sliding groove 164 of the driving member 10 (near the end of the handle 12) abuts against the protruding shaft 22 of the locking member 20, and the locking device securely fixes the functional module 100 to the frame 200.

Referring to FIGS. 5 and 7 , when the function module 100 needs to be removed, the handle 12 of the driving member 10 is pulled outward, so that the mounting shaft 80 is disengaged from the fixing portion 4124 of the sliding slot 412 of the receiving member 40 and The second end of the sliding groove 164 of the driving member 10 (the end away from the handle 12) abuts against the pair of protruding shafts 22. The handle 12 is further pulled outwardly, and the driving member 10 drives the locking member 20 to disengage the locking portion 28 from the fixing hole 202 of the frame 200 and retract into the receiving member 40. At this time, the spring 60 is The function of the functional module 100 can be removed by stretching and deforming the support member 30 and deforming the torsion spring 70 by further pulling the handle 12 outward. After the function module 100 is removed, the handle 12 is released, the spring 60 is restored to deform, the driving member 10 is moved to the receiving member 40 to be reset, and the torsion spring 70 is restored to deform. The first twisting arm 72 is deformed. The support member 30 is pushed to rotate, and the locking member 20 is reset to extend the locking portion 28 out of the receiving member 40, so that the functional module 100 can be installed next time.

The preferred embodiment of the locking device of the present invention eliminates the need for screws and other tools during the loading and unloading process of the functional module 100, and in the extraction process, the handle 12 can be unlocked and the functional module 100 can be extracted. Come out, the operation process is convenient and fast.

In the above embodiment, the role of the torsion spring 70 is to rotate the support member 30 to be reset. It can be understood that in another embodiment, other elastic members may be used instead of the torsion spring 70 to achieve the reset of the support member 30. For example, a spring with a hook at each end is hooked at one end The other end of the second side wall 43 of the receiving member 40 is hooked to the first end of the support member 30 (near the end of the locking member 20). When the locking member 20 rotates the supporting member 30, the spring connected between the second side wall 43 of the receiving member 40 and the supporting member 30 is deformed by tension. The spring is restored to deform so that the support member 30 is rotated to be reset.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
