an improvement on logic boy's answer:
pin type:
block trigger:https://www.instructables.com/id/K_NEX-GUN/
true trigger:https://www.instructables.com/id/The_El_Diablo_Assualt_Pistol_R_45/
sear trigger:https://www.instructables.com/id/SR_commado_v1/

slingshot type:
high-tension:https://www.instructables.com/id/knex_smallish_cannon/
sniper (light sear):https://www.instructables.com/id/SR_V2/
tomboyrme trigger (specialised sear):https://www.instructables.com/id/Knex-carbine/
ratchet:https://www.instructables.com/id/The_Sipriani_Rifle/
counter-tension:https://www.instructables.com/id/Knex-light-crossbow/

and if you want to be picky, the trigger on the corner crossbow is considered a high tension sear trigger. and the counter-tension trigger i showed is an outer mech, the other ones are inner-mechanisms.
Ok lets see.
for pin type guns:
Block trigger-Killerk's https://www.instructables.com/id/K_NEX-GUN/
True trigger-The jamalam's https://www.instructables.com/id/Storm-221-V24-Battle-Sniper/
Sear trigger-DJ Radio's https://www.instructables.com/id/SR_commado_v1/

for slingshots its a bit harder
Ratchet system-Viccie.B 1993's https://www.instructables.com/id/The_Sipriani_Rifle/
No real name but Y connector triggers-Viccie.B 1993's https://www.instructables.com/id/The_White_Tiger_V2_Rifle/
there are others but most of them atre one offs
True triggers ------TBAP
Block triggers------knex cannon
Sear triggers-------Sipriani
Sipriani does not have a sear trigger. It has a slingshot ratchet trigger.
