发明名称 Switch type on/off structure for hoisting magnetic disks
摘要 A switch type ON/OFF structure for hoisting magnetic disks has a handle turnable towards one side to demagnetize and towards another side to generate a magnetic force to attract and move a work piece. The handle is hinged on one end surface of a hoisting magnetic disk which also has a first detent member and a second detent member. The first and second detent members can stop the turning of the handle. The handle further has an extensible latch member at one side spaced from the handle at a selected interval. The latch member has a distal end slidable over the second detent member and extendable downwards to allow the second detent member to be wedged in the interval and anchored. Thereby the hoisting magnetic disk can provide the magnetic attracting force and hoist and move the work piece safer.
