The invention discloses a firmly connected foldable construction fence, which comprises a first fixing frame, a second fixing frame, connecting hole pieces, screws, a third fixing frame, a joint seat, fixing bolts, a support rod, a fixing rod, and a
screw thread. Holes, Connection Blocks, Round Hole Blocks, Shock Springs, Threaded Posts, Thin Sheets and Reflective Strips. The present invention is simple in structure, easy to install, convenient for users to fold and disassemble, is beneficial for full-
package transportation, has the function of shock absorption and buffering, is beneficial to the protection of thin plates, is convenient to replace partially damaged thin plates, and avoids the damage caused by overall dismantling and replacement. The waste of material, by removing the connecting holes, it is convenient for the first
fixed frame and the third
fixed frame to rotate respectively against the front end of the second
fixed frame to achieve the effect of folding and placing, and the damping spring is arranged on the rear end of the sheet and According to the shrinkage of the shock-absorbing spring, the shock-absorbing and buffering effect of the thin-plate sheet is achieved when it is impacted by the outside, which is beneficial to the protection of the thin-plate sheet.
