Anticreep chain movement；The effect for not installing fixed block, intermediate branch helix and teeth on anti-drop block in the last one link units is
The last one is not needed in connection chain link unit；Two are symmetrically provided on anti-drop block one end two sides in the last one link units
The effect on a inclined-plane that breaks ground, which is easy for anti-fall off chain, easier to be entered in soil；First in one of link units is oblique
Installed teeth cooperation on intermediate branch helix on block and the second skewback and adjacent link units, and the first skewback and the second skewback
The effect for being located at teeth two sides is cooperated with teeth two sides, to achieve the purpose that preferably to limit link units；The
The one L shape limited block other end stretches out the length dimension of the second guiding groove and the 2nd L shape limited block other end stretches out the first guiding groove
Length dimension it is identical effect be allow triggering arc plate release the first L shape limited block and the 2nd L shape limited block simultaneously
To the position-limiting action of link units；The length dimension that the first L shape limited block other end stretches out the second guiding groove is equal to triggering arc plate
The effect of thickness be that triggering arc plate is allowed to release the position-limiting action to link units of the first L shape limited block.
In use, when anchor pole is not used, guide rail is located in anchor bar body, and anti-fall off chain is located at straight in guide rail
In line segment, anchor pole can be made when entering in soil in this way, resistance is smaller；When anchor pole in use, anchor pole is put into thing first
In the hole first accomplished fluently on cob wall；Secondly the first operating stick of driving is moved, the first operating stick will will drive drive block movement, drive
Motion block will drive guide rail to move, and guide rail will be along the first guide groove movement, so that guide rail can move out anchor pole
Body；Guide rail at this time will face handle hole, the second operating stick is protruded into handle hole at this time, the second operating stick will be to anti-
De- one driving force effect of chain, when anti-fall off chain encounters the triggering arc plate installed in guide rail, triggering arc plate at this time will
To the first L shape limited block and the 2nd one active force of L shape limited block, the first L shape limited block at this time will be along the second guiding groove
Movement, the 2nd L shape limited block will be moved along the first guiding groove；The first L shape limited block and the 2nd L shape limited block of movement will
It is separated from the region of teeth, adjacent two link units at this time will be rotated around straight pin, so that anti-fall off chain can
To adapt to the arc section in guide rail, when the second operating stick is pushing anti-fall off chain to move out the arc section in guide rail, into straight
When line segment, the first L shape limited block at this time will be restored to original position, the limit of the 2nd L shape under the action of second spring
Block will be restored on original position under the action of third spring, anti-fall off chain at this time will the first L shape limited block with
Under the position-limiting action of 2nd L shape limited block, it is in linear state, so that soil will be will receive by moving out the anti-fall off chain of anchor bar body
The active force of earth achievees the purpose that anti-dropout so that anchor pole is not easy to fall off out of soil.
