It depends on which book you use as a reference.

If using Xanathar's, then no, that book fumbled on tinker's tools despite having the artwork on its page that would align with other depictions of what tinker's tools should have been.

If you just use the PHB, tinker's tools are used for EXACTLY what you would be looking for.
Go to page 37.
"Tinker: You have proficiency with artisan’s tools (tinker’s tools). Using those tools, you can spend 1 hour and 10 gp worth of materials to construct a Tiny clockwork device"
