The present invention relates to a multi-type pole fixing device. More specifically, a 4:3 screen and a 16:9 screen can be selectively installed by using the pole fixing device, so that a user can simply view a video conference, a lecture, or a film. In addition, the pole fixing device can be attached to the outer surface of an outdoor camping vehicle or a vehicle using a magnetic structure, so that the pole fixing device can be simply used and easily carried by the user. The multi-type pole fixing device includes: a pole fixing member including a front case having installation holes formed in corners of a square body and inclined at a predetermined angle, having two coupling grooves and coupling protrusions formed at mutually different angles inside the installation holes, and having a pole insertion hole formed in a square outer surface, and a rear cover having the same shape as the front case and having two fixing protrusion and fixing grooves formed at mutually different angles in the installation holes; upper and lower coupling terminals coupled to the coupling grooves of the front case, provided therein with pole coupling holes formed at mutually different angles, and having fixing pieces provided at rear portions thereof with holes and coupling protrusions provided at an outer surface thereof; a cover plate installed on the installation holes of the front case and the rear cover, and having insertion holes matched with the pole coupling holes of the upper and lower coupling terminals; a rectangular fixing plate screwed with an outer surface of a support plate as the support plate having a coupling groove, in which the magnetic structure is inserted and installed, is integrated with a rear surface of the rear cover; and a plurality of coupling members provided with threads so that a stand-type pole is screwed with the outer surface of the support plate. |
