Using the above scheme, it can preferably be suitable for some occasions for needing often to move water pump, be also applied for putting down
Normal occasion can limit the rotation of runner by docking for pin shaft and the spin-ended hole of runner, guarantee the static condition of water pump with this
Stablize；The convex cooperation offer with sliding slot is slided in operating process up and down, and sliding convex and annular groove cooperation limits and keeps pin shaft and stops
Trepanning or the grafting for connecing hole.
Further preferably are as follows: crown cap is arranged in the top of the pin shaft, is provided between the top cap and bottom plate and forces pin
Axis is detached from spin-ended hole and keeps and connect the second spring of hole grafting.
Using the above scheme, it avoids leading to pin shaft because of vibration because gasoline engine water pump is in movement or operation
Fall into spin-ended hole or be detached from bracket.
Further preferably are as follows: the annular groove is provided with the groove with sliding convex cooperation along the axial upper inside wall of perforation.
Using the above scheme, by the effect of second spring, pin shaft with can have when spin-ended hole grafting it is upward pre-
Pressure can prevent to slide convex turning to sliding slot due to gravity by the cooperation of groove.
Further preferably are as follows: the bracket includes the restocking connecting with wheel carrier, the undercarriage connecting with runner, is fixed on undercarriage
Telescopic rod between restocking and the damping spring being sheathed on telescopic rod, the upper and lower side of the damping spring respectively with it is upper
