Now prevent secondary pulse device 82 and jump bit 83 from being dropped downwards along spacing slide rail 81；
Position under being located at support column 822 relatively due to jump bit 83, therefore the impact head 833 of jump bit 83 can directly and pedal
Crank shaft contact on shaft holder 9, that is, realize impact test of the impact head 833 to crank shaft, simultaneously because impact head 833 is right
The impact of crank shaft, crank shaft can give the acting in opposition of impact head 833, cause gravity block 831 to break through the folder of elastic clip tight set 832
Tight effect and sliding certain distance again fix by relative support post 822 along support column 822, again during, prevent secondary pulse
Device 82 can also slide certain distance along limit track 81, due to Action of Gravity Field, prevent secondary pulse device 82 and jump bit 83
Can it is upper slide to a maximum height after fall again, it is anti-now because jump bit 83 be located at the more top position of support column 822
Only secondary pulse device 82 and jump bit 83 jump bit 83 behind whereabouts will not contact crank shaft, but be supported by support column 822
On impact base 824, secondary pulse of the jump bit 83 to crank shaft is avoided.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
