Locking mechanism for communication module and communication device

A locking mechanism for a communication module, the locking mechanism comprising:

• a module frame, and a handle, a upper-and-lower bolt, a handle stopping mechanism and a handle self-locking mechanism, wherein the handle, the upper-and-lower bolt, the handle stopping mechanism and the handle self-locking mechanism are arranged on the module frame;
• wherein the handle is connected with the upper-and-lower bolt through the linkage mechanism of the upper-and-lower bolt;
• when rotating under the action of a force, the handle is moved with the upper-and-lower bolt through the linkage mechanism, and the communication module is inserted into or pulled out of communication device by the elastic function of the upper-and-lower bolt;
• wherein when the communication module is not inserted into the communication equipment, the stopping bolt on the handle stopping mechanism stops the handle and the handle is locked;
• when the communication module is inserted, the stopping bolt on the handle stopping mechanism separates from and releases the handle;
• and
• wherein when the communication module is inserted, the handle is closed, the bolt of the handle self-locking mechanism withdraws under the extrusion of a clamping seat on the module frame, the bolt clamps the clamping seat, and the handle is locked.
