打氣筒轉接頭（立式打氣筒）

Went through two camping trips before I misplaced the original, and this spare screws on exactly like it should. The bayonet fitting clicks into my pump without any wobble, so inflating the tent mattress took no extra effort.

Glad I could order this as a spare — my original got buried on a campsite somewhere, and the screw-on connection to the tent valve is just as snug as I remember. Bayonet side clicks into my pump without any wobble, so inflating the mattress took no time at all.

The bayonet fitting locks onto my floor pump perfectly, no wobble at all. Screwing it onto the tent valve took seconds, and it feels solid enough to survive a few camping trips without getting lost again.
