As Figure 10, shown in Figure 11, release the embodiment 3 of energy safty device, release the embodiment 3 of energy safty device, comprise the dunnage 63 of rotating position between clutch handle 11 small ends be assemblied on the housing 1 and the housing, and the torsion spring 62 that is connected between dunnage 63 and the shell 1, dunnage 63 is the inclined-plane with the fitting surface of clutch handle 11 small ends. when clutch handle 11 is pressed, the small end of clutch handle 11 lifts, dunnage 63 is supported on below the small end of clutch handle 11 by the torsion spring effect, clutch handle can not be automatically reset, wait to start finish after, push dunnage 63 contacts and clutch handle resetted the constraint of clutch handle 11 small ends.

As shown in Figure 12 and Figure 13, release the embodiment 4 of energy safty device, comprise the torsion spring 72 that is connected between the pressing plate 71 that rotates position between the clutch handle 11 long ends be assemblied on the housing 1 and the housing and pressing plate 71 and the shell 1, pressing plate 71 is provided with the locking plate 73 that extends towards clutch handle 11, locking plate 73 is provided with the groove 74 of joining with clutch handle 11 cards, and is excessive by the inclined-plane between the end of locking plate 11 and the groove 74.When clutch handle 11 is pressed, the long end handle body of clutch handle 11 falls and enters along the inclined-plane of locking plate 73 in the groove 74 by locked and can not reset, wait to start finish after, push pressing plate 71 and can drive locking plate 73 releases and clutch handle 11 is resetted and join by sloped roof with locking plate again.

Working procedure of the present utility model and principle are:

Just around thermal energy storage process: the crank insertion is just shaken in the hole outside axle 6 clockwise, just first on axle 6 drives clutch shaft gear 7, clutch gear 8 around driving gear 5 ', drive, driving wheel 17 by clutch gear 8 are done and are clockwise rotated, whirlpool spring axle 29 rotates with driving gear shaft 18, and whirlpool spring 31 is tightened at this moment.On the whirlpool spring 31 full after, driving wheel 17, clutch gear 8 with just around ratchet 5 interlockings, just finish around energy storage.

Pre-boot process: finished to move decompression handle 12 around energy storage originally, after the decompression backguy adjustment pressurized handgrip axle 13 with projection depress little push pedal 14, wobble gear push pedal 16 is depressed in little push pedal 14, and wobble gear push pedal 16 is rotated and promoted wobble gear clutch pellet 28 is that the center swing is meshed itself and starter receiver 3 with its eccentric shaft.If any the interlock error, lazy-tongs start compensation.The elastic force that the correct back of engagement rod 24 is subjected to self to connect torsion spring rotates and falls also block on the swivel stop of fixing on the wobble gear clutch pellet 28 25.During decompression meter plate 15 be subjected to self rotate the upper end with the torsion spring effect and enter in the groove on decompression handle axle 13 side faces, decompression handle 12 is in the neutral position, rod 24 passes through to be connected in swing pull bar 37 drives 10 swings of clutch lock tube and is in the open position, the diesel engine reduction valve is opened, the timing insurance is closed, and pre-boot process is finished.

Exempt to shake start-up course: after pre-boot process is finished, with clutch handle under the hand 11, the clutch release, the whirlpool spring discharges, and it is first around ratchet 5, just around driving gear 5 ', wobble gear 27, starter receiver 3 rotations, simultaneously that driving wheel 17 rotates counterclockwise drive, plate 15 rotated the constraint of releasings to decompression handle axle 13 when timing wheel 20 clockwise rotated it on timing shifting block 22 pushing tow decompression meters, decompression handle 12 is subjected to spring tension to fall down to reset, diesel engine reduction valve closure, and diesel engine can start.On this moment clutch axle sleeve 36 or the shell (according to release can safty device embodiment select) on release can safty device with the clutch handle locking, clutch handle can not reset.

Automatic thermal energy storage process: starter is in the energy state of releasing, after diesel engine works well, the user moves the release mechanism of releasing the energy safty device, release and can safty device the axial limiting of clutch handle or clutch movable axis be disengaged, clutch handle 11 is subjected to the spring force effect and self-return, clutch gear 8 and clutch shaft gear 7 lockings, energy storage begins automatically.Starter cup 3 drives wobble gears 27, just around driving gear 5 ', clutch shaft gear 7, clutch gear 8, do and clockwise rotate by drive, the driving gear 17 of clutch gear 8, whirlpool spring axle 29 rotates with driving gear shaft 18, this moment, the whirlpool spring 31 was tightened.Driving gear 17 drive timing gears 20 rotate counterclockwise simultaneously, when automatic energy storage is nearly finished, the timing insurance is opened by timing shifting block 22, timing shifting block 22 pushing tow rods 24 rotate and the restrained end of 24 pairs of swivel stops 25 of rod are lifted, the wobble gear clutch pellet 28 at swivel stop 25 places is subjected to self to connect under the elastic force effect of spring and resets around eccentric shaft 38 counter-clockwise swings, and the wobble gear 27 of wobble gear clutch pellet 28 outer rings is separated automatically with starter receiver 3.Connect pull bar 37 simultaneously on the rod 24 and promote 10 rotations of clutch lock tube and locking clutch handle 11.Whole process is finished, the diesel engine proper functioning, and the starter driving mechanism separates.
