It moves the side of spring 23；In two 24 moving process of fixture block, when two fixture blocks 24 be moved fully to it is right on adjusting slider 15
When two adjusting 27 insides of guide groove answered, user is corresponding rectangular by adjusting square groove 31 corresponding on the first swing rod 2
Drift drives the first swing rod 2 so that the first swing rod 2 is moved up and down relative to adjusting slider 15；By adjusting the upper of the first swing rod 2
Lower movement can adjust spacing of first swing rod 2 between 3 one end of the second swing rod and adjusting rod 22；Because double leval jib transmission is former
Reason, spacing of the first swing rod 2 of change between 3 one end of the second swing rod and adjusting rod 22 can change the first swing rod 2 and swing
In the process in the case where swinging same angle, the first swing rod 2 is transmitted to the amplitude of fluctuation on the second swing rod 3；It can change
The velocity of rotation of output shaft 9；When spacing of first swing rod 2 between 3 one end of the second swing rod and adjusting rod 22 increases, pass through
The amplitude of fluctuation that input shaft 4 is transmitted on the second swing rod 3 will increase；So that the amplitude of fluctuation of third swing rod 7 increases；I.e.
17 amplitude of fluctuation of arc driving plate increases, and the velocity of rotation of output shaft 9 becomes larger；That is the first swing rod 2 close to 3 one end of the second swing rod with
When spacing between adjusting rod 22 increases, the velocity of rotation of output shaft 9 becomes larger；By adjusting the first swing rod 2 close to the second swing rod 3
Spacing between one end and adjusting rod 22 can adjust the output power of speed changer；Realize speed changing function.
The empty effect with rectangular adjustment hole 13 in adjusting side opened on mounting shell 1 in the present invention is that people is facilitated to adjust first
The position relationship of swing rod 2 and adjusting slider 15；First the first swing rod 2 is moved in adjustment process and is opened on mounting shell 1
Adjusting side's sky and 13 matched position of rectangular adjustment hole, are then being adjusted.
Specific implementation mode：When the speed changer that people are designed using the present invention, pass through manual adjustment adjusting slider 15 first
With the relative position of the first swing rod 2；Then driving input shaft 4 rotates, and input shaft 4 can drive the 4th swing rod 5 around 4 axis of input shaft
Line rotates；The rotation of 4th swing rod 5 drives the 5th swing rod 6 to swing；5th swing rod 6, which is swung, drives the first swing rod 2 around adjusting rod 22
Axis rotation；The rotation of first swing rod 2 drives the second swing rod 3 to swing；Second swing rod 3 swing on the one hand drive third swing rod 7 around
The swing of fixing axle 16；On the other hand second swing rod 3, which is swung, drives arc driving plate 17 to be swung around fixing axle 16；Arc drives
The swing of plate 17 will drive second gear 8 to rotate；The rotation of second gear 8 drives output shaft 9 to rotate；I.e. input shaft 4 drives output
Axis 9 rotates.
