Magnetic pickup mechanism

The invention relates to a magnetic pickup mechanism. The magnetic pickup mechanism comprises a guide rod, a spiral spring, a guide base and an installation base, wherein the guide rod is arranged in the spiral spring in a penetrating mode, a flange is arranged on the upper portion of the guide rod, and protrusions are arranged on the lower portion of the guide rod; the upper end of the spiral spring abuts against the flange of the guide rod, the lower end of the spiral spring abuts against the installation base, and a magnet is fixed to the lower end of the guide rod. Guide grooves are formed in the side wall of the guide base, the guide grooves include at least one long groove and a short groove, the bottom of the long groove is communicated with the bottom of the short groove, the top of the long groove is higher than the top of the short groove, and the height difference H, in the length direction of the guide rod, between the top of the long groove and the top of the short groove is equal to or larger than that the attraction distance of the magnet; the protrusions of the guide rod are arranged in the guide grooves; the guide rod is arranged in the guide base in a penetrating mode, and the guide base is fixedly installed in the installation base. According to the magnetic pickup mechanism, an external power source or air source is not needed, and use cost is reduced; pickup is controlled through vertical movement of the magnet, and the magnetic pickup mechanism is small, exquisite and convenient to use.
