Features [Wide scope of application] The flexible arm can be fixed at any angle, is simple and quick to use, and is widely used in mechanical calibration and technical measurement. [Stable performance] The base of the universal base holder is equipped with a permanent magnet alloy and a central locking mechanism with a lock spring. [Easy to use] The structure of the magnetic base holder stand is simple, easy to use and maintain, high sensitivity, stable and reliable. [Sturdy and durable] The outer shell of the magnetic base holder is made of high wear-resistant alloy steel, and the outer shell is chrome-plated, which can achieve rust-proof, durable and beautiful effects. [Safe and reliable] Opening/closing the magnetic base can be moved at any time without reaction force, avoiding damage to the instrument and workbench. 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.
