Loss prevention magnetic core clamping device

The utility model discloses an anti-damage magnetic core clamping device which comprises a supporting foot and a supporting plate, the supporting plate is installed on the top of the supporting foot, movable grooves are formed in the two sides of the supporting plate, a rotating disc is installed on the front face of the supporting plate, and a protective shell is installed on one side of the supporting plate. By installing the protective shell, a worker can place a magnetic core to be clamped and machined in the protective shell, the cotton pad is soft and can wrap the magnetic core, and then the worker needs to hold the pull belt to pull the cover plate anticlockwise to rotate with the connecting rod as the circle center under the supporting of the supporting plate, so that the cover plate covers the top of the protective shell; therefore, the effect of preventing the magnetic core from being adsorbed to outside metal impurities is achieved, and a storage space is provided for the magnetic core to be clampe
