Design a latch mechanism

Job ID: 32595642

Budget: €8 – €30 EUR

I need a geometry of a latch mechanism used to lock and release a lifting tong.
Job consist to draw 3D model of the mechanism only and to verify by simulation the correct function and 2D drawing of the wheel and hook (lifting tong must be neglected). 3D file shall be provided by a STEP files and 2D drawing by dxf or dwg (2007) files. Units shall be millimeters.
Is not important the software that you will use (SW, Inventor...) and is not important the dimensions of the parts. For example you can start with a wheel of 100 mm diameter.

You can find and example of the mechanism on the following video:
