The specific embodiment
As shown in the figure: on the installation shaft 7 of crosswise fixed setting, be socketed with bearing 6, be hinged with the acceleration arm 12 that stretches out on the bearing 6, the top ends of acceleration arm 12 is set up the synchronous pulley 8 that is driven by engine installation, the bottom of acceleration arm 12 is hinged with clamping plate 16, on clamping plate 16, set up synchronous pulley 18, winding synchronous belt 10 on two synchronous pulleys 18,8, be connected with the tightening device of two synchronous pulleys 18,8 on the clamping plate 16, one retractor device top is hinged on the installation shaft 7, and the bottom of this retractor device is hinged on the acceleration arm 12.
Above-mentioned engine installation is for being arranged on the frequency modulation motor 3 on the acceleration arm 12 by flange, synchronous pulley 8 is connected on the axle head of frequency modulation motor 3 by key and end cap 2.Described tightening device is the tensioning spring 13 that the bottom is connected connecting panel 15 tops, and the top of this tensioning spring 13 is arranged on the acceleration arm 12, also can be connected with pull bar 14 in tensioning spring 13 ends, and tensioning spring 13 is arranged on the connecting panel 14 by pull bar 14.
Retractor device comprises by support plate 11 and is hinged on cylinder 9 and piston rod 19 thereof on the acceleration arm 12, piston rod 19 bottoms are hinged on the support plate 11, piston rod 19 tops are goed deep in the cylinder 9, be fixed with the also outwardly directed obliquely installation portion 20 that is bending on installation shaft 7, cylinder 9 tops are hinged on the top ends of installation portion 20.
