8. circuit fuse protector according to claim 7, it is characterised in that: the medium position of the constraint block is provided with Trigger ramp, the distance between trigger ramp and bottom plate are directed toward vertical plate two by vertical plate one and are gradually reduced, and sliding block is close to vertical plate 21 Offered on end face with mounting groove two connect and positive open trough opposite with trigger ramp, the vertical plate two is close to sliding block one end Face is provided with positive triggering inserted link opposite with open trough, by extruding of the triggering inserted link to trigger ramp, force constraint block along Mounting groove two overcomes the elastic force effect slide downward for shoring spring, and constraint block is released to the rotational restraint of block, constraint block around Its rotation axis is rotated close to vertical plate two and is detached from wing plate two, and compressed spring two will drive sliding block multiple far from the sliding of vertical plate two Position；

The constraint block is provided with reset magnetic stripe at the top of one end face of block, and block is made of ferrimagnet, it is described about It is provided with reset inclined-plane at the top of beam block, resets the distance between inclined-plane and bottom plate and is gradually increased along the direction vertical plate two of vertical plate one.
