Tooth is raised, and the top of the interior bar is provided with mounting seat, and supporting plate is provided with mounting seat, the scalable support of teeth boss
The outside of bar is provided with installation set, and the side of installation set is provided with extension adjustment device, and the inside of the extension adjustment device passes through
Axostylus axostyle is provided with the ratchet used with teeth male cooperation, and the side of the ratchet is provided with rocker arm, and the top of rocker arm
Handle is installed, it is evenly distributed with the dowel hole run through on the telescopic pole below the interior bar, and interior bar bottom is determined
Support pin is installed in the pin-and-hole of position.
Preferably, four sides of the fixed anchor bottom are all provided with anticreep hangnail.
Preferably, the termination of the support pin is provided with fixing nut.
Preferably, the edge of telescopic pole top interior bar is provided with sealing ring.
Preferably, it is arranged with Anti-slip cover on the handle.
Compared with prior art, the beneficial effects of the utility model are：Under the mine roadway support expansion link relative to
Traditional supporting is more perfect with apparatus function, and structure is more stable, and the telescopic pole and extension adjustment device of setting can be with
The length of telescopic strut is adjusted according to demand, is easy to strut to apply to different environment, is improved the practicality of strut, setting
Supporting plate and the fixation anchor and fixed plate of bottom are easy to strut to be fixed in the tunnel of mine, are easy to mine roadway support
Construction usage, the stability and security of telescopic strut are improved, by being used cooperatively for ratchet and teeth bulge-structure, be easy to
The regulation of telescopic pole height, the dowel hole being equipped with can be fixed to interior bar, avoided because of top pressure
Situation that is excessive and causing interior bar decline, is easy to promote the use of.
