The specific embodiment
Referring to Fig. 1 and Fig. 2; Manually turning handle 15 is captiveed joint through semi-round key 14 with imput shaft 3; The disk of imput shaft 3 ends is captiveed joint with the drive pin 12 of lockplate 5; Locating dowel pin 13 on the lockplate 5 vertically passes the disk on the driven shaft 8 and places the spacing breach of disk, and foot throttle mechanism 7 is connected with driven shaft 8, and driven shaft 8 other ends are connected with the engine governed speed handle through driven rocking arm 16 and connecting rod.
Referring to Fig. 2; The overriding clutch that present embodiment adopts is the roller double rolling key clutch, and double rolling key clutch is made up of housing 1, recoil spring 9, pull back spring 10, roller 11, lockplate 5, locating dowel pin 13, drive pin 12, and said lockplate 5 outer rims are symmetrical set two breach; This breach is corresponding with drive pin 12 positions on the imput shaft 3; Lockplate 5 is consistent with imput shaft 3 center of gyrations, and lockplate 5 end faces are provided with a locating dowel pin 13, is arranged on the symmetric line of two breach; Said housing 1 is fixing on complete machine, and recoil spring 9 is positioned at imput shaft 3 end disc and the lockplate 5 corresponding grooves that are provided with.When hand throttle is handled; Drive imput shaft 3 through manual turning handle 15 and rotate, stir roller 11 through the drive pin on the imput shaft 3 12, roller 11 drives lockplate 5 through pull back spring 10 and rotates; Overriding clutch was in and surmounted state this moment; Locating dowel pin 13 on the lockplate 5 drives driven shaft 8 and rotates, and then drives driven rocking arm 16 and connecting rod rotation, rotates control throttle size thereby drive the engine governed speed handle; Manual accelerator is handled when stopping, and roller 11 is being locked at lockplate 5 on the housing 1 under the effect of pull back spring 10, and this moment, overriding clutch was in lockup state; Thereby realize the positioning action of hand throttle; All can drive lockplate 5 during the forward and reverse rotation of imput shaft 3 in this mechanism and rotate synchronously, when the drive pin on the imput shaft 3 12 was motionless, lockplate 5 can not be rotated by wedging; Realized the particularity of location, and handled light.
