Gag lever post on hand.
As further describing for above-mentioned technical proposal：
Six limited blocks form hexagonal structure.
As further describing for above-mentioned technical proposal：
Expansion plate there are two being arranged altogether in each fixed plate, and vertical center line pair of two expansion plates about fixed plate
Claim.
As further describing for above-mentioned technical proposal：
There are six the screw rod is arranged altogether, and the angle of six screw rods between any two is 60 degree.
As further describing for above-mentioned technical proposal：
The bayonet of the rotating bar and groove top is rotatablely connected.
In the utility model, first, sleeve body is internally provided with six limited blocks, and the inside of six limited blocks is equal
It is rotatably connected to screw rod, the side of screw rod is provided with fixed plate, then fixed plate is led to for six sides on the outside of fixed screw
Crossing adjustable mode makes fixed plate is fixed more to stablize, and preventing it, screw falls off in the rotation, secondly, screw rod
Inside open up fluted, the top of groove is rotatablely connected by bayonet and rotating bar, and the underfill of rotating bar has flowing
Liquid passes through the extruding of rotating bar, you can pushing plate is driven to be moved to both sides, you can pushes expansion plate, therefore such setting
It can adapt in the screw of different pore size size, practicability is stronger.
