This is the design that Deere used on wagons that works quite well.
The bottom of the telescoping tongue is open so that part #13 catches the end and you cannot pull the tongue out of the tube should the latch release. I had some latches like #6 bent and then welded a 2" of 5/8x1-1/2 flat for the latch to catch on. I bought the spring #7 from Deere. I measured the parts I had on a wagon.
IIRC the outer tube is 4x4x3/16 wall and the inner slide is 3-1/2x3-1/2x3/16. I used a reach I had from a wagon I had lengthened for the inner tongue but could easily have used a square tube and cut a slot for the emergency stop.
