Fixinig plate is provided in slot, the both ends of fixinig plate have been separately formed through-hole, screw, the screw are both provided in each through-hole
It is then passed through valve rod fixing groove bottom across through-hole and is fixed by nut；The valve rod forms key with the fixed one end of butterfly plate
Slot, is molded on butterfly plate fluted accordingly, and a flat key is inserted into keyway and groove.
By designing above：When valve rod loosens, it is not required to butterfly type valve to be separated and pneumatic executive item, it is only necessary to twist in outside
Tight nut can fasten valve rod, greatly facilitate rundown process, improve working efficiency；By the design of keyway, groove and flat key,
It is rotated without pin to realize.
The utility model is further arranged：It is provided with gasket between the fixinig plate and the bottom of valve rod fixing groove and makes fixation
The both ends of piece form locking gap with valve rod fixing groove bottom.
By above-mentioned design, fixinig plate both ends slight bending can be made, so that nut with some power of pre-add when mounted
It is tighter, and due to slight deformation, make the direction of screw stress also fine rotation, so can pneumatic locking effect.
The utility model is further arranged：The upper end of the screw is hexagon, and the both ends of the fixinig plate are molded anti-rotation
Slot, anti-rotation groove are hexagon.
By the design of anti-rotation groove, when tightening nut, screw is fixed automatically, and thus facilitate nut tightens work
Make, facilitates installation.
The utility model is further arranged：The bottom of the fixed platform forms hook, and spanner is hung on hook.
By above-mentioned design, when needing to repair and tighten nut, do not need it is pretty troublesome look for spanner, so that work is become
It must be more convenient.
The utility model is further arranged：Hanging groove is formed in the middle part of the spanner, spanner is hung over by hanging groove on hook.
By forming the design of hanging groove in the middle part of spanner, to enable spanner to hang on hook, and hanging groove setting is being pulled
In the middle part of hand so that spanner the space occupied smaller.
The utility model is further arranged：One end of the spanner forms square groove, and the other end of spanner forms hexagonal
Straight slot.
By the different design in both sides, it is adapted to different nuts and consumer's hobby.
