Bar is just right with starting shaft, the fixing starter toothed wheel combination of another handss, and one holds the handle of assembling accessory, is pressed downward the same of torsion spring
When, turning handle, drive the combination rotation of Kick-start axle, realize sector gear and starter toothed wheel group that Kick-start axle group is closed
The starter toothed wheel closing engages according to matching requirements, by after the taking-up of torsion spring assembling accessory after engagement, you can ensure on torsion spring inner ring
Limited post be close on sector gear.During dismounting, reverse use can complete the dismounting of torsion spring, still possess efficient and convenient and
The feature of safety.
The accessory of the present invention is that the construction featuress being specifically designed for torsion spring in motorcycle Kick-start mechanism design, for anti-
Rush torsion spring in starter mechanism auxiliary install, enable to torsion spring can be more prone to, safety compression and torsion, conveniently apply
Power and ensure that force equilibrium, conveniently makes the combination of Kick-start axle and starter toothed wheel combination be in just engagement.Avoid
Cause torsion spring resilience to hurt sb.'s feelings in installation process, and make install more labor-saving, convenient and fast it is ensured that torsion spring install peace
Quan Xing, improves production efficiency.This accessory has filled up the vacancy that engine assembly is similar to torsion spring assembling accessory, makes the assembling of torsion spring
More convenient, more laborsaving, safer, faster.
