Hello I am now working on a project to improve a crimping tool primarily used to connect polybutene pipes to brass-copper fittings, the crimp action being deformation of the copper sleeve to fully accentuate the pipe.

As I was browsing patents looking for inspiration, I came across an idea: Aperture mechanism.
Aperture Mechanism

Is it possible to accommodate such a mechanism for a handheld tool to supply force in compression. It looks promising at first because if I am able to design it, then it can be used to crimp pipes of various sizes.

Any thoughts and comments?
