As shown in the figure, the present invention is made up of actuating unit and link gear, in actuating unit, comprise main shaft 1, energy-stored spring 2, tooth bar 3 and mainshaft gear 4, energy-stored spring 2 roof pressures are on tooth bar 3, tooth bar 3 is meshed with mainshaft gear 4, mainshaft gear 4 links to each other with magnetic damp mechanism with transmission mechanism by one-way wheel mechanism, one-way wheel mechanism is by one-way wheel 5, roller 6 and spring 7 constitute, roller 6 and spring 7 are arranged in the breach 8 on one-way wheel 5 circumference, one-way wheel 5 is connected with main shaft 1 by key 9, the interior week of the periphery of one-way wheel 5 and gear bush 11 movingly, and the close-fitting mutually of the gear 10 in the periphery of gear bush 11 and the transmission mechanism.Magnetic damp mechanism is made of magnetic force line cutting device 12 and potentiometer 13, and the electric current that magnetic force line cutting device 12 produces links to each other with potentiometer 13 by lead, and mainshaft gear 4 connects transmission magnetic force line cutting device 12 by transmission mechanism.The embodiment of door closer-holder of the present invention comprises door closer and floor spring, under the assembling form of door closer, its link gear comprises the upper and lower connecting rod 14,15 that an end is hinged, last connecting rod 14 is hinged on the base 16 with the doorframe Joint, and the other end of lower link 15 is connected on the main shaft 1 of actuating unit.When opening the door, people's hand-power draws back or advances the fan door, because doorframe maintains static, makes mainshaft gear 4 rotations that are contained in the actuating unit in the fan door upper door closer housing, drive tooth bar 3 translations, make energy-stored spring 2 compressions, the storage elasticity energy is simultaneously because the single effect of one-way wheel mechanism, transmission mechanism is given in main shaft 1 not power transmission, magnetic damp mechanism is not worked, undamped power, and fan door is just opened with the speed that manpower draws back (or promotion).When the people lets go, energy-stored spring 2 releases energy, tooth bar 3 drives mainshaft gear 4 reverse rotations, drive the one-way wheel 5 of one-way wheel mechanism by key 9, under the effect of spring 7 power, one-way wheel 5 more tightens roller 6, gear bush 11 is given in power transmission, because gear 10 tight fits in gear bush 11 and the transmission mechanism, gear 10 rotations, and other gears at different levels that drive simultaneously in the transmission mechanism are done raising speed or reduction of speed rotation, magnetic damp mechanism work, magnetic force line cutting device 12 in the magnetic damp mechanism can adopt motor or generator, and the size of the electric current of generation is to reach by the resistance in the regulator potentiometer 13.Because the size of electric current influence the size of non-magnetic conductor, so when the resistance of potentiometer 13 is more little, then the electric current that passes through of coil is big more, so, damping force is also just big more, and the speed of closing the door is also slow more, otherwise the speed of closing the door is fast more.Under the assembling form of floor spring, when opening the door, people's hand-power draws back (or propelling) fan door, final drive shaft 17 rotates synchronously, drive shifting block 18 suitable (or contrary) clockwise rotations on the final drive shaft 17 in the floor spring, make positioning roller axle 19 translation forward, because train wheel bridge 20 and lower plate 21 are equipped with in positioning roller axle 19 above and below, so upper and lower clamping plate 20,21 are translation forward synchronously together also; Link to each other with upper and lower clamping plate 20,21 with double-screw bolt 23 because of core bar 22 front ends again, the rear end links to each other with slide block 25 with bearing pin 24, and that just drives slide block 25 translation forward, because energy-stored spring 26 front ends are installed in the inner housing 27 motionless, energy-stored spring 26 is compressed so, the storage elasticity energy.Meanwhile, because tooth bar 28 is connected with slide block 25 usefulness screws 29, also translation forward of tooth bar 28 so drives power transmission shaft 30 rotations, but because the single effect of one-way wheel mechanism, magnetic damp mechanism is not worked,, that is with regard to undamped power; Door just draws back the speed of (or propelling) by people and rotates.When the people lets go, energy-stored spring 26 releases energy, slide block 25 translation backward, drive core bar 22, go up lower plate 20,21, also translation backward of positioning roller axle 19, force shifting block 18 reverse rotations on the final drive shaft 17, the speed of its reverse rotation is just determined by magnetic damp mechanism that its course of work and principle and door closer are identical.
