Referring again to Fig. 2 or Fig. 7, described fixing frame 5 has one first center hole 51, vertical component 52 and three limit position parts 53.Described vertical component 52 is erected on the bottom of fixing frame 5, and a hollow bolt 18 is arranged in vertical component 52; Described limit position part 53 described in three is erected on the left side of fixing frame 5, right side and top respectively, often this limit position part 53 is all equipped with one for locking the second locating piece 19 of described rocking arm 31.
Referring again to Fig. 2 or Fig. 8-10, described rocking arm 31 is provided with the second center hole 311 and the 3rd open-work 312; Described 3rd open-work 312 is positioned at the bottom of rocking arm 31, and described flexible axle 6 through hollow bolt 18, and is achieved a fixed connection with rocking arm 31 by described 3rd open-work 312; The top of described rocking arm 31 is upwards swelled, and forms a boss 313, to make two limit position parts 53 can locking rocker arm 31 better.Described cranking arm 32 has spread out spindle 321 and a locking hook 322, and this spreads out spindle 321 successively through described first center hole 51, second center hole 311, and is fixedly connected with described rocking arm 31 by one first locating piece 20; Described locking hook 322 be positioned at crank arm 32 tail end, this locking hook 322 is connected by governor spring 10 with described second joint 42.
Referring again to Figure 10-11, described return unit 7 comprises the first open-work 71, second open-work 72, torsion spring 73, two fixed component 74; Described first open-work 71 is positioned at the upper right of fixing frame 5; Described second open-work 72 is positioned on rocking arm 31, and described first open-work 71 and the second open-work 72 are linked by torsion spring 73; Fixed component 74 described in two all lays respectively at the left and right sides of rocking arm 31 below position second open-work 72.
Referring again to Fig. 2, described shutdown unit 8 comprises baffle plate 81, shutdown features 82 and a power source (not shown); Described baffle plate 81 is fixed on pull bar 2; Described shutdown features 82 links with power source, and this shutdown features 82 comprises an operation unit 821, and described operation unit 821 is located at baffle plate 81 front accordingly, and arranges in opposite directions with this baffle plate 81.When applying shutdown unit 8 and working; pulled by power source or promote shutdown features 82; the operation unit 821 pairs of baffle plates 81 in shutdown features 82 are made to impose one to reducing fuel injection quantity direction i.e. power to the right; pull bar 2 is forced to move right; thus engine stop is rotated; shut down the setting of unit 8, emergency shutdown and deficient oil pressure protection function can be realized.
Referring again to Fig. 1 or Fig. 5-6, when applying the present invention and working, one external force F1 is applied to rocking arm 31, speed setting parts 3 are rotated (counter clockwise direction namely shown in Fig. 1 is rotated) towards increasing fuel injection quantity direction, speed setting parts 3 rotate and cause governor spring 10 to move right, then governor lever 4 is driven to move right by governor spring 10, governor lever 4 moves right and causes correcting spring 9 to compress to the right simultaneously, namely correcting spring 9 compresses to described adjustment member 14 direction, due to correcting spring 9 have elastic force thus must cause shift fork 1 be subjected to displacement left namely to increase fuel injection quantity direction move, now shift fork 1 is in starting upgraded position (see Fig. 6), namely shift fork 1 is subjected to displacement left by previous declared working condition position (see Fig. 5), and be in starting upgraded position (see Fig. 6), and pull pull bar 2 namely to move to increase fuel injection quantity direction left by the bulb 13 of shift fork 1, thus the fuel injection quantity of Injection Pump (not shown) is increased, when after engine start, when rotating speed rising reaches certain value, sliding sleeve (not shown) can apply one to the right namely to the active force N (see Fig. 1) reducing fuel injection quantity direction to shift fork 1, namely shift fork 1 just moves to reduction fuel injection quantity direction to the right, and namely moved to reduction fuel injection quantity direction to the right by bulb 13 pushing drawing rod 2 of shift fork 1, thus reduction amount of fuel delivered of oil jetting pump, this process eliminates starting upgraded stroke S simultaneously, after rotating speed reduces, sliding sleeve (not shown) can be moved to the left, the active force N of sliding sleeve (not shown) to shift fork 1 also weakens gradually, shift fork 1 also can move towards increase fuel injection quantity direction simultaneously, governor lever 4 moves right, when to increase after certain fuel injection quantity i.e. governor lever 4 move right certain displacement time, governor lever 4 can be blocked by counteraction member 16, thus fuel injection quantity is no longer increased, so realize engine governed speed.
When speed setting parts 3 being locked in a fixed position with two second locating pieces 19 and not rotating, pull bar 2 also can remain unchanged after moving certain displacement, thus makes fuel injection quantity keep certain value, thus makes the rotating speed of motor keep fixing; In like manner, utilize two second locating pieces 19 that speed setting parts 3 are locked in different pivotal positions, the fuel injection quantity that Injection Pump keeps different can be made, different rotating speeds is kept from motor, therefore by changing the pivotal position of speed setting parts 3, and change the fuel injection quantity of Injection Pump, thus make the rotation speed change of motor or make engine stop.As can be seen here, locking the position of speed setting parts 3 by adjusting two second locating pieces 19, the two poles of the earth speed governing and the full distance speed regulating function of arrangements for speed regulation can be realized.
When to when applying directed force F 3 (see a Fig. 2) upwards through the flexible axle 6 of hollow bolt 18, flexible axle 6 can drive speed setting parts 3 to rotate to increase fuel injection quantity direction, by the transmission of a series of parts to this active force, pull bar 2 is finally caused to move to increase fuel injection quantity direction, thus the fuel injection quantity of Injection Pump is increased, therefore can realize remote function by flexible axle 6.And when the directed force F 3 put on flexible axle 6 disappears, under the effect of the torsion spring 73 in return unit 7, described rocking arm 31 can set back, thus pull bar 2 is also set back, and then the speed making the speed of motor also recover original.
