L-squares.

Embodiment:

The leaf spring 10 that the utility model is a spool by housing 9 (being that upper shell and lower shell body are connected and fixed with bolt) and leaf spring axle 12 with gearwheel 13 seam of one two combination is formed, the leaf spring axle by Bearing Installation on output shaft 1, output shaft uses bearing fixing on housing, the ratchet 18 that leaf spring axle inside has spring 19 to push down withstands on the ratchet 21 of seam on the output shaft, there are the off-centre 15 fixing bearings 14 of inserting at the ratchet back side, in combination shell one side an axle 37 energetically is installed, the axle upper and lower is provided with free wheel device energetically, the outer surface groove that is with of its internal clickwork 26, spring and spring seat 28-29 that ball 27 and top ball are arranged in the groove, there is foreign steamer 25 in the ball outside, seam has lever 23 on the foreign steamer, the extension spring 30 that lever is hung on the bearing pin 31 is pulled on the bearing of eccentric installation on the output dog end, in the symmetrical holes on the outer wall steel ball 34 is arranged in the middle of the axle energetically, steel ball outside withstands on energetically axle and goes up in the groove in small gear 35 skirt sections of installing, steel ball the inside withstands on the mandrel 36 that is withstood by tightening silk 32 securing stage clips 33 in the axle energetically, the groove that loosens steel ball is arranged in the middle of the mandrel, the mandrel upper end has a push rod 44 to stretch out the starter housing, has the set square triangle 45 of startup to push down above.The leaf spring ragged edge has the induction piece 17 by extension spring 20 tensions, the induction piece seam is on timing axle 50, regularly an end of axle is inserted on the bearing pin of lower shell body, the upper end passes the timing sheet 53 by extension spring 48 tensions that upper shell is fixed with rotating plate 49 and slides, the screw of adjustment 51-52 is regularly arranged on the sheet, casing centre and output shaft are equipped with clutch base 8 with one heart, are slidingly fitted with clutch 6 by clutch sleeve 7, are the sliding sleeve 4 that release bearing 5 is fixed above the clutch.During installation, earlier clutch 2 is installed on the diesel engine belt pulley with one heart, and this starter that will install release spring 3 is fixed on the next door of diesel engine by support, and make this starter output shaft and belt pulley concentric, operating grip is installed in driver's next door, starts that pull bar 46 will start set square triangle 45 and L-square 57 is held simultaneously.When starting diesel engine, starting handle is pushed away forward, at this moment, pull bar is earlier moved cut-off clutch the top of clutch base to and sliding sleeve 4 and clutch 2 is meshed fully, and then will start set square triangle and depress push rod, after mandrel is forced into the end, steel ball moves in the groove of mandrel, and the gearwheel out of hand and engagement of the small gear on the axle rotates under the tension of leaf spring energetically, because the effect of ratchet, output shaft drives the diesel engine belt pulley and rotates, at this moment diesel engine starting.After the startup, the unclamp operation handle, this moment, regularly sheet 53 withstood cut-off clutch lever 54, and cut-off clutch can not separate, and resetted and start set square triangle, mandrel also resets under the effect of stage clip 33 simultaneously, the rotation of belt pulley drives output shaft and rotates, and the eccentric bearing of installing is done eccentric motion on the ratchet, and the small gear of energy being passed on the axle energetically by lever (resets owing to start set square triangle, steel ball is automatically with small gear and shaft locking energetically), small gear drives gearwheel and rotates to leaf spring energy storage again.When the leaf spring last lap begins to roll, because the effect of extension spring, induction piece drives regularly, and axle rotates, driving rotating plate simultaneously rotates, regularly sheet is because the regulating action of screw 51 makes regularly sheet throw off the lever of cut-off clutch according to the degree of rolling, and cut-off clutch resets under the effect of extension spring 47, clutch separates down with the effect that slides over release spring 3 simultaneously, and starter quits work.
