Machining and grinding device for medical instrument production

The machining and polishing device for medical instrument production comprises a supporting base, the top end of the supporting base is fixedly connected with a working machine body, the surface of the working machine body is fixedly connected with two sets of protection plates, and the inner side of the working machine body is slidably connected with a polishing wheel; supporting plates are fixedly connected to the inner sides of the two sets of protection plates, and a rotating handle is slidably connected to the inner side of one set of protection plates. Through connection between a limiting block and the rotating handle, the rotating handle can be conveniently limited, and the situation that normal grinding cannot be achieved due to rotation of the rotating handle during work is prevented; through connection between a limiting clamping ring and a connecting clamping groove, a limiting effect on a connecting sleeve rod can be conveniently achieved, the connecting sleeve rod is prevented from driving a fix
