The specific embodiment

With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.

According to illustrated in figures 1 and 2, the described a kind of bag rod structure of present embodiment includes the metal side tube 2 of hollow, and metal side tube 2 is coated with end face and is foursquare plastic casing, plastic casing is formed by 1 clamping of two identical in structure U-shaped plastic sheaths, and U-shaped plastic sheath 1 is the one extrusion moulding; 12, one shortwall 12 ends of two shortwalls that U-shaped plastic sheath 1 includes a longwell 16 and is vertically connected on the same side, longwell 16 two ends are provided with connection-peg 11, and another shortwall 12 ends are provided with the inserting groove 17 that matches with described connection-peg 11; The retaining wall 111 that described connection-peg 11 includes plug 112 and is positioned at plug 112 outsides, described inserting groove 17 includes external groove sidevall 171 and internal groove side wall 172, external groove sidevall 171 closely offsets with retaining wall 111, and external groove sidevall 171 is provided with the circular arc bayonet socket 1711 that cooperates chucking with plug 112 towards internal groove side wall 172 1 sides; Be connected with a reinforcing wall 14 between each shortwall 12 inboard and longwell 16 inboards, reinforce between wall 14 and longwell 16, the shortwall 12 and surround isosceles right triangle; The inboard of longwell 16 is provided with three second supporting walls 15 of equidistantly arranging, and second supporting walls 15 in the middle of being positioned at is connected in the point midway of longwell 16, and the end of each second supporting walls 15 and metal side tube 2 surfaces offset; The inboard of shortwall 12 is provided with one first supporting walls, 13, the first supporting walls, 13 ends and metal side tube 2 surfaces offset; Described first supporting walls 13, shortwall 12, reinforce wall 14, longwell 16, second supporting walls 15 and surround pentagonal first cell body 101 successively, surround second cell body 102 of U-shaped between adjacent two second supporting walls 15 and the longwell 16.
