Tay kẹp Extensor (phụ kiện – cần bộ extensors kit riêng)

Extra parts to add to an injection molded extensors kit (available from http://www.mathmechs.com) to make an extensor grabber toy. Designed by Will Segerman and me.

The plunger comes in three parts. The shaft part (with one thumb hole) should be inserted through the square barrel part (with two finger holes), and then the small cross piece glued onto the shaft part. The crosses on the small cross part and the square barrel part should come to meet when the shaft is pulled out as far as possible from the square barrel part.

Extensors are protected by US patent 11,702,327.
