Features Smooth universal painted chrome arm can be fixed at any angle, easy and quick to use, widely used in mechanical correction and technical measurement. Switch on/off magnetic base to move at any time without reaction force, avoiding damage to the gauge and working desk. The base is equipped with a permanent alloy magnet and a central locking mechanism with anti-loose springs. Concise structure, easy to use and maintain, high sensitivity, stable and reliable. Made of highly wearproof alloy steel, the shell is chrome‑plated to achieve rust‑proof, durable and beautiful results. Description:Magnetic base holder also known as universal base holder is widely used in the machine manufacturing industry, which is also used in various scientific research institutions. There is a cylinder with a bar-shaped permanent magnet inside it. And the position of the outer base is a soft magnetic material, which is a kind of ferrite material that is easy to magnetize or demagnetize in the weak magnetic field. Features:1.
