Every time I wash my hair with a shower head, I need a person standing beside me to help me hold the flush, otherwise the result of one-handed operation is that the collar is soaked. The shower buckle on the wall is not only high but also immovable, so it is.....

This small suction cup is inspired by the computer's suction cup camera. The snap suction cup at the bottom can firmly suck the hook part on the smooth surface of the object. (Although you can't suck it all the time, washing your head should be enough)
The hook part is wrapped with soft rubber and is easily deformed by the metal core strip, so that you can pinch it as you like...
Usually hang a shower head, hang clothes, hang a bag, or even hang a mobile phone (as long as you don't stay up late to watch a movie, otherwise you are likely to see half of the mobile phone hit your face).
Let's have a few clumsy renderings and look forward to your advice.

The suction cup is transparent soft silicone, which can provide better suction

The surface material of the press buckle for extruded air is also soft rubber, which provides appropriate pressure and increases the loss resistance of the maximum stress point of this small product.
