It states right card middle part of holding tightly and is fixedly connected with telescopic rod hangers；The left free end for holding card tightly is fixedly connected with locking engaging lug, institute
It states the left middle part for holding card tightly and is fixedly connected with strut engaging lug, the strut engaging lug is located at same level with the telescopic rod hangers
On line, horizontal-clamping wedge is connected on the locking engaging lug, horizontal-clamping wedge is connected with the locking block.
In this structure, the horizontal-clamping wedge is an elongated band steel, and the free end of horizontal-clamping wedge is designed with slot hole, long
Vertical clamping wedge is installed, the vertical clamping wedge is wedge shape, wide at the top and narrow at the bottom in hole.
In this structure, the anti-down telescopic strut of interlocking includes outer tube, and outer tube is a pipe, and the right end of outer tube is set
In respect of connector, connector is flat, and connecting hole is provided on connector, and connecting hole is connected with the strut engaging lug by connecting pin
It connects, the installation of the outer tube other end screws hand handle, is fixedly connected in outer tube equipped with interior telescopic rod, the left end of the interior telescoping tube
There is hook, hook is connected with the telescopic rod hangers.
The utility model has the advantages of be：Due to this structure of the utility model, the utility model is embraced using left
Tight card and right two, holding card hold card tightly and hydraulic prop are held tightly, and centre is connected with telescopic strut, multiple monomers
Hydraulic prop gets up according to row or row interlocking, when having individual monomers hydraulic prop leakage, unloading occur, being detached from top plate, also not
It can topple over and hurt sb.'s feelings；When there is bump, because pillar is large area interlocking, hydraulic prop will not be pushed over, avoids getting over
Therefore occur, when use, is time saving, laborsaving, and easy to operation, using effect is good.
