We are experts in music stand phone holder, because our boss loves to play the trumpet. So we developed a series of trumpet phone mounts, music instrument score clips and lyrics phone stands. Live broadcasts and outdoor performances often use various types of live broadcast stands and music stands. We have focused on the development of round pipe clamps and powerful claw mount bases of different sizes of pole/pipe/tube/rod/handlebar mount, so that mobile phones can be installed on pipes of various sizes, such as tripod pipes on the tube of the selfie stick, on the handle of the stroller. 6-21mm/9-23mm/14-28mm/16-45mm pipe diameters can be clamped. Our round tube mobile phone clamp is made of nylon and corrugated fiber material with thick silicone gasket. It is of good quality, durable and tight clamping force. Not only can it be used to clamp round wind instruments, it can also be fixed on bicycle handlebars, suitcase trolleys, and subway bus handrails. Suitable for 4.5-6.5-inch mobile phones, you can freely rotate and adjust the angle 360 degrees or 720 degrees! Our round pipe clamps can be matched with different 1/4 ball heads, four-button ball heads, GoPro ball heads, 17mm ball heads, etc.! All mic stand phone holders can be freely matched and combined to meet everyone's different application scenarios! Small size, exquisite design, stable quality, cheap price, strong flexibility and wide application range, it is deeply loved by everyone and purchased in bulk!
