Outbound, which nails on to wear, is connected to small pressure spring, and connecting pin is connected with the locking plate of pluggable rack gear by bindiny mechanism.The utility model is set
There is a rebound protective effect after setting small pressure spring, in the locked state, when back pulling gear check lock lever, locking plate will not horse back and tooth
Item separates, and needs an external force that could unclamp on wraping plate.Small pressure spring is separately positioned on the two sides of gear adjusting block.
Preferably, the bindiny mechanism includes the pull rod of the L-type to link together with connecting pin, pull rod is another
End is positioned on tray main body by pressing plate by fixing screws by pull rod pin connection locking plate, locking plate.Bindiny mechanism is by multiple portions
Part composition, is installed more convenient in this way.Rack gear is equipped with multiple teeth, in this way can be with multi-gear adjustment.
Preferably, being connected with the different spacing block set of length and buffering convex block, gear on the gear adjusting block
The lower part of adjusting block is lined with elastomer block.It can guarantee that gear adjusting block has cushion effect at runtime by elastomer block.
Preferably, being connect by pin one with pedestal in the middle part of the tray main body；Support base is connected by pin two
Wraping plate, the hole that wraping plate is connect with support base are set as kidney slot.Wraping plate can be limited by kidney slot.
Therefore, the utility model is utilized is arranged small pressure spring and elastomer block at gear adjusting block, it is ensured that locking plate exists
It will not be disengaged immediately when unlock, needing to press wraping plate could complete to separate, and seat is more comfortable when switching gear, structure letter
It is single, reasonable.
