point of middle screw thread chimb 531 and 102 groove of pressure wheel and incrementally increases, be from the central point of wheel shaft 51 to The contact point of screw thread chimb 531 and 102 groove of pressure wheel can be incrementally increased in rotation with moving down, and with move down height It is same, that is to say, that the central point of wheel shaft 51 is moved downwardly how many, while screw thread wheel 53 being driven to make in moving down rotation The contact point of screw thread chimb 531 and 102 groove of pressure wheel increases how many, make rotating turret 101 under the action of screw thread wheel 53 not It moves down, the first chimb 1071 is maintained at pressed status (as shown in figure 15) to pulley 103, thus can make pressure assembly 100 Always there is a downward pressure to be applied on suspension 50, and power source be transmitted to the right end of swinging frame 10 through drawstring 40, Raise 10 right end of swinging frame to lower swing left end simultaneously with suspension 50, at the same time, in 10 clockwise oscillation of swinging frame When, due to the unidirectional drive performance of ratchet mechanism 30, at this time main shaft 20 driven under the driving of subsequent drive unit ratchet 31 after Continuous to rotate counterclockwise, then band pawl 32 rotates clockwise swinging frame 10, and the front end of pawl 32 is slipped over from 31 back of tooth of ratchet, when convex Wheel 107 main shaft 20 be rotated by 171 ° after so that the first chimb 1071 is separated with pulley 103, the second chimb 1072 It copes with pulley 103 and separated state, 101 left end of rotating turret loses the state of being pressed down, pressure assembly 100 is applied with suspension 50 pressure releases only have the suspension 50 of the application of drawstring 40 and 101 pressure wheel 102 of rotating turret to be produced in 10 right end of swinging frame Raw gravity, while first gear 91 turns to part tooth and second gear 92 is disengaged from driving condition, so far driving unit It is simultaneously again at rear stage driving unit and downward in 10 left ends of gravity bottom moving frame of clump weight 13 to revert to original state It swings, driving unit is again introduced into rotate main shaft 20 and do work, and repeats the above course of work.It recycles repeatedly, so that two Under the mutual cooperation of a driving unit, main shaft 20 is able to lasting rotation and external output power.
