1, Stable Clamping: Pumping flexion installation artifact, clamping stable, fast and convenient installation. Precision threaded rod, smooth moving, large torque. Movable clamping head, clamping smooth, do not hurt objects. 2, Strong & Smooth: Pumping flexion installation auxiliary clamping structure to understand it, to better use it. Round plum knob, strong, smooth and doesn't hurt your hands. 3, Stainless Steel Material: selection of stainless steel, clamping object, not easy to deformation. coating, treatment. The anti-slip barrier pad is not easy to damage the material, the clamping is flat, the force is even, and the object is not hurt. 4, Thickened Design: The thickened clamping is stable and not deformed. It has stronger bearing capacity and is not easy to deformation and fracture. No need for extra clamp, including clamp itself, quick locating and fastening 5, Comfortable Grip: Soft edge plum knob grip comfortable, the overall curved design, rotation time and labor saving.
