On be provided with perforation the second circular hole effect be easy for installation straight pin；The periphery of middle branch helix side is installed on fixed block
Effect on end face is easy for installation teeth；The effect that middle branch helix periphery is circumferentially uniform to be provided with many a teeth is
Coordinate with the first L-shaped limited block and the second L-shaped limited block, so as to achieve the purpose that spacing chain link unit motion；First L-shaped is spacing
Block is slidably installed with the second guiding groove, and first L-shaped limited block one end stretch out the second shifting chute effect be easy for it is spacing
The movement of teeth, the effect that the first L-shaped limited block other end stretches out the second guiding groove are easy for triggering arc plate triggering anti-fall off chain, from
And anti-fall off chain is caused to be adapted to the arc section in guide rail；Second spring is located in the second guide groove, the installation of second spring one end
In the second guide groove, the effect that the other end is installed on the second guide block is just with being acted on to one restoring force of the second guide block；First
Skewback one end is installed on the fortune that the effect that the first L-shaped limited block is stretched out on the end face of second shifting chute one end is easy for limitation teeth
It is dynamic；Second L-shaped limited block is slidably installed with the first guiding groove, and the first shifting chute is stretched out in second L-shaped limited block one end
Effect is easy for the movement of limitation teeth, so that adjacent link units movement is restricted, so that anti-fall off chain can
With in linear state, the effect that the second L-shaped limited block other end stretches out the first guiding groove is coordinated with triggering arc plate, so as to arrive
The purpose for the arc section being adapted to up to anti-fall off chain in guide rail；3rd spring is located in the 3rd guide groove, the 3rd spring one end peace
In the 3rd guide groove, the effect that the other end is installed on the 3rd guide block gives the 3rd guide block one restoring force effect；Second skewback
One end is installed on the effect that the second L-shaped limited block is stretched out on the end face of first shifting chute one end and is easy for having played with teeth cooperation
The position-limiting action of effect；The effect of non-installation side journal stirrup is easy for the promotion of the second operation lever on anti-drop block in first link units
Anticreep chain movement；Not installing the effect of fixed block, middle branch helix and teeth on anti-drop block in last link units is
Last need not be in connection chain link unit；Two are symmetrically provided with anti-drop block one end two sides in last link units
The effect on a inclined-plane that breaks ground is easy for anti-fall off chain and easier can enter in soil；First in one of link units is oblique
Teeth cooperation, and the first skewback and the second skewback are installed among on block and the second skewback and adjacent link units on branch helix
The effect positioned at teeth both sides is coordinated with teeth two sides respectively, so as to achieve the purpose that preferably to limit link units；The
The one L-shaped limited block other end stretches out the length dimension of the second guiding groove and the second L-shaped limited block other end stretches out the first guiding groove
The identical effect of length dimension be so that triggering arc plate can release the first L-shaped limited block and the second L-shaped limited block at the same time
To the position-limiting action of link units；The length dimension that the first L-shaped limited block other end stretches out the second guiding groove is equal to triggering arc plate
The effect of thickness be so that triggering arc plate can release the position-limiting action to link units of the first L-shaped 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, it can so cause anchor pole when entering in soil, resistance 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 operation lever of driving is moved, the first operation lever will drive drive block to move, and 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 operation lever is stretched into handle hole at this time, the second operation lever will give anti-
One driving force effect of de- chain, when anti-fall off chain runs into the triggering arc plate installed in guide rail, triggering arc plate at this time will
Give the first L-shaped limited block and the second L-shaped limited block one active force, the first L-shaped limited block at this time will be along the second guiding groove
Movement, the second L-shaped limited block will be moved along the first guiding groove；The the first L-shaped limited block and the second L-shaped limited block of movement will
The region of teeth is separated from, adjacent two link units at this time will surround straight pin rotation, so that anti-fall off chain can
To adapt to the arc section in guide rail, when the second operation lever is promoting anti-fall off chain to move out arc section in guide rail, into straight
During line segment, the first L-shaped limited block at this time will return to original position under the action of second spring, and the second L-shaped is spacing
Block will be returned on original position under the action of the 3rd spring, anti-fall off chain at this time will the first L-shaped limited block with
Under the position-limiting action of second L-shaped limited block, in linear state, so that soil will be subject to by moving out the anti-fall off chain of anchor bar body
The active force of earth, so that anchor pole is not easy to come off out of soil, achievees the purpose that anti-dropout.
